My Twin 20G Build

[20G_VR4]

Hey guys, I thought I'd post this thread up here to share pictures and keep my progress on this car updated as often as possible for you. There is a lot of custom work done to this car which I am willing to discuss. I am also very open to criticism, suggestions, questions, and anything else that can contribute not only to my build, but the community as a whole.

Alan, is it ok that I post the link to my old thread on 3si as a reference? I know there were a lot of important questions and topics discussed, and it would be a waste to just throw it away.

I am going to also reserve the next couple posts to keep the pictures in a nice, orderly and presentable fashion to track the progress from the beginning to the very end.

[Mr Faust]

AHHHHH Holy shit that is badass, you're doing a fine job with all that fabrication :O

[DocWalt]

Hot damn. That is badass. Great fab work!

[20G_VR4]

Markoverclock from Turbochargers.com is doing 99% of the fab work. I just installed the seats and thats about it. I give him a helping hand whenever he needs is, but I dont have the technical expertise to do any of the fab work shown in the pictures. In fact, you can see him in some of the pictures. It has taken 2 1/2 years so far working a couple hours on a few Sundays each month. This actually went from a simple header/turbo fab into an all out build. The might as well syndrome kicked in very early on.

[thor'svr4]

dam thats a lot of custom work!!!! i really like how those seats match the stock charcoal / tan interior. how do the seats feel?

[FstAsVR4]

AMAZING job are you sticking with the 3.0? What power gains are you expecting? (sorry if this was already answered on 3si I just saw this)

[FastOldGuy]

Looks like you are going in the right direction.

[20G_VR4]

the seats feel comfortable, but sit a bit high on the rails. Im 5'10, and my head is about an inch and a half away from the headliner.

From what I researched, the motor is stock, but the rods looked polished when we pulled off the oil pan, and also had some kind of stamp on them, but Mark couldnt tell because of bad lighting. Also, the 109,000 mile block has no signs of scarring, scratches, detonations, or anything. It was actually very clean when we pulled off the heads. I talked to all the previous owners, but they all said that nothing had been done to the car besides regular maintenance. The motor is going to stay stock for a while, as I dont really have the funds for a built block.

We are going to tune it using 93 pump gas as well as E85. We're hoping for 600awhp on E85, which shouldnt be too hard to do. I just dont want to push it past that to keep the block alive. In a year or two, ill upgrade to a built 3.1L

[PsykoGamer]

this is just an awesome build...maybe it should be moved to the Projects link though? Might be easier for people to find if they want to check out progress instead of it getting buried in the forum :). Definitely want to follow this to see how it turns out myself. Looks sick.

[a2j]

nice work.

[92RT-TT]

That is awesome. You make me want to do a crazy build someday! keep up the good work.

[lawdogg]

Maveroverclock can weld. Looks fantastic. You gonna spin it up higher than 7k?

[20G_VR4]

yea, mark can pretty much turn these cars inside out and put them back together, no sweat. Im going to rev it to about 8-8300, but no more. Once again, the stock crank probably wont be able to handle much more than that, so i dont plan on stressing the motor too much until i can build it.

[KeithMac]

Very nice work!.

[Atrosity]

mmm....looks slow! :)

[20G_VR4]

Im sorry for not updating you guys in a while. The car is almost done. I don't have any current pictures, but we should have the car started and on the dyno by the end of May. My senior year of pre-med has been kicking my ass, so I haven't been able to finish it as quickly as I wanted. Here's a teaser pic from a few weeks ago. Its more complete now than what is shown...

man good luck thats like 40g's

[GTO Assassin]

Insane!

Scotty

[Turbo Beast]

Hope you guys replace that oilcooler, looking good!

[20G_VR4]

I still have the stock oil cooler; no aftermarket ricer parts here. Im building this 20G beast right.

but seriously, I'll replace the oil cooler if oil temps get too high, but I feel that the stock one will be adequate with nothing in the way of its airflow. The FMIC pipe is routed underneath and behind it, so its got a clear shot through the bumper. Its pretty much the only stock part left bolted to the motor, apart from the stock bottom end itself.

[boosted3s]

I'm jealous

[93SlugTT]

omg! my i want.

sooooo, i am going to need to know

1. what wheels are those.
2. when the car is done
3. where to find it
4. when your not going to be home
5. do you own a dog and if yes, does he like steak
6. where are the keys.

1. 18x8.5 front, 18x9.5 rear 5Zigen FN01R-C
2. Hopefully it will be tuned and running on both 93pump and E85 by mid May
3. Houston, Tx.
4. I am usually out every day from 7am-7pm or later.
5. I have a 1 and a half year old pitbull. Loves steak and possibly human flesh.
6. The keys are always in my pocket.
6. Did you forget what you were saying while thinking about possibly stealing my car? haha

[93SlugTT]

lol

yes, but i will leave my 15g, semi built bottomend new everything stealth tuned to e85. i think it will be by 500mark. steak for dog..check. hotwire 101 book, check lol mapquest check

[IPD]

subscribed. i'll be the resident pessimist on the performance of 20g's on a 3.0L engine--i'll believe it when i see it. i would expect much greater results from an extra .5L. i just don't think a 3.0 can gobble that much air.

[93SlugTT]

even if it doesnt spool until 4900, it will be a highway monster. even with the old school 20g turbo lol.

[a2j]

so 20Gs wont fit like 16Gs do?

[vr4tune]

Send your 20g's to Matt (snakeskinner) for some billet compressor, titanium aluminide turbine wheel love. That will hep with spool time.

[Pensky3thousand]

Send your 20g's to Matt (snakeskinner) for some billet compressor, titanium aluminide turbine wheel love. That will hep with spool time.

I can attest to this. My Ti/Al 16g's start spooiling at like 2krpm lol.
Good luck with everything. I'm interested to see results.

[IPD]

if that's on a 3.0L...DAYUM! i think i'll probably end up sticking with chinabay turbos for my stroker...i like not having boost at idle. :)

[93SlugTT]

boost at idle is the greatest,

acts like a supercharger, power of a turbo lol

its a win/ win.

i think its all the piping is done right, along with a stright intake into each turbo. ( blow though) it will spool around 3-4 which will be a monster. be creeping on some supra's

[93SlugTT]

also i forgot to say something, I am not 100% sure, but i think the harness is wrong, and with it being bolted down like that wouldn't it break your shoulders since the harness bars alot alittle movement to theres a sudden stop to the body. or something along those lines, i thought i heard something about that then on the news some kid died from that. but im not 100% sure how it was set up but i think it was something like this

The harness point should be above your shoulder. Just like normal seat belts.

[20G_VR4]

I fixed that issue today. Those pics are pretty old. I installed a roll bar and got most of the motor put back together.

I really want Ti/Al 20gs, that would be awesome, but for now im going to see what this setup can do. Im shooting for 600awhp on E85. Next year, Ill throw in a built motor, Ti/Al 20Gs, and push it.

[familyMAN]

Wow! Looks awesome! Very tidy.

[VR-4 0wnz j00]

Nice cage, that should make nice mounting points. Looking forward to you finishing the build.

[20G_VR4]

If anyone can help, I need the jumper harness that goes from the 6-pin connector (pictured below resting on the front wastegate) to the temp sensors on the radiator.

http://a7.sphotos.ak.fbcdn.net/hphotos-ak-snc6/208469_551804668688_182702853_31296710_3983887_n.j pg

Thanks,

[20G_VR4]

i just want to update you guys with what's left to do:

Get fans working (need the jumper harness to them or find a way to wire them in)
Install Crank and accessory pulleys and belts
Install 300m output shaft and billet tcase
Clean and install charge pipes
Install Fuel Bulkhead
Wire up water temp, oil temp, oil pressure, IAT, and MAP sensors
Weld in a throttle stopper
Reinstall seats
Install rear rotors and SSB brake lines all the way around
Reinstall Hood and Front Bumper
Prep motor and start and tune the car on E85

I think that pretty much sums it up.

[Modern 3kGT]

Subscribed for the results... Good Luck! Great Work!

John

[20G_VR4]

All the wiring is done except for the fans. I still need to find a way to bypass the jumper harness or get a new one. We were going to prime the motor and start it last night; I had a video camera ready, but the ECU fuse blew right before we were ready and we didnt have any more 15amp fuses.

Whats left?

Weld in throttle stopper
Reinstall seats and glovebox
Install 300m output shaft and billet tcase
Install rear rotors and SSB brake lines all the way around
Reinstall Hood and Front Bumper
Start the car and tune it on E85

Unfortunately, I have finals this week and a wedding to go to next week. Looks like the car wont be started till 3 Sundays from now

[milkshakes]

Holy god.

Your engine bay is sex.

[IPD]

Holy god.

Your engine bay is sex.

agreed. it's almost as pimp as buell's.

[STLVR4]

agreed. it's almost as pimp as buell's.

Its nice for sure but I wouldn't go that far...

[Chatzvr4]

Very nice high end job! Glad to see someone that is very good with thier hands taking pre med. The bay looks so clean i am thinking you scrubbed in before hand lol

[20G_VR4]

Just got the motor together last night. Spent 3 hours from 12am-3am trying to start it with little luck. We can get it past start up but it wont idle :(

Markoverclock loaded a map from his stealth onto my EMS, but adjusting it is a bitch. I was wondering if anyone can provide me with a solid base map to at least help me get my car idling?

I have PTE 780cc/min injectors, 272 cams, 90mm throttle body, twin walbros, and TD05-20Gs. If anyone has anything remotely close, please help me out! I would greatly appreciate it!

--

Whats left to do?

Install Billet Transfer Case
Install rear rotors and SSB brake lines all the way around
Start, Idle, and Tune
Reinstall front bumper and hood
Reinstall Glovebox and seats

[20G_VR4]

Quick Update. Got her running Sunday, but ran into a few snags.

My BOV isnt opening, forcing air back towards the turbos, so I'll need to get a new spring for it. Also, one of my injectors isnt spraying any fuel. Im going to call IPS today and see what I can do about replacing it or maybe the set.

Otherwise, its nearly finished. I just need to put the interior, front bumper, and hood back together.

Pics and vids of it running and together should come up sometime next week.

[AdamVR4]

When do you anticipate being ready to race? Any interest in meeting at San Antonio Raceway? It's about time Houston had another fast 3S :)

[20G_VR4]

Ill be able to come up anytime after August 1st, provided I get a decent tune on it. It should be back on the streets this coming weekend as long as I get those few minor issues fixed.

[n2nsanity]

Wow! Subscribed.
I hate you....

[my923ksl]

build looks very nice, what type of fans are you using?

She's a whole car again. Ran into a thousand and one small gremlins when trying to start her this weekend and managed to fix them all. Getting her registered and throwing in a new alternator so I can take her on the road to tune her tonight. Pics plus vid coming up tomorrow!

PS, she sounds awesome... except the walbros are a little too loud for my liking at idle, but who can complain with the way it sounds at WOT?

[IPD]

#1 reason why i bought two densos for my new build. walbro is LOUD.

[futurevr4man]

wow nice build!! i am doing 20g's as well so im curious as to your spool times and power output. you gonna go balls to the wall with the pump and stay semi-mild on e85? how much boost you think you will pull off before knocking on pump?

if you want a 3.1L i have one you could snag! pm me if you are interested!

[AudibleSilence]

You're bringing that beast to the TX gathering right?

[20G_VR4]

PM me details and ill be there.

[AudibleSilence]

Nice PM sent!

[familyMAN]

How do you like those seats? Did you lose any headroom?

[20G_VR4]

The seats are really comfortable for a light seat... certainly not the worst ive sat in. I lost a lot of headroom with the brackets. With a helmet, Im roughly an inch or less from the headliner.

[familyMAN]

Any way to tilt them back more for a bit more head room?

Car looks great by the way! I'll be digging into a "mini-me" Green 1st Gen TD05 car soon:) Smaller set up though...evo3 w/E85.

[20G_VR4]

Ive run into some problems while tuning with mark. Every time I get the turbos to start spooling, it runs out of fuel and goes way lean. I have 4psi by 3300rpm, but run out of fuel, even when mark has rescaled the map and added over 33% more fuel. Mark and I were thinking it might be one of the fuel pumps. They are horridly loud; unlike anything I've ever heard. I can hear them over the exhaust at cruising. Also, after the fuel pumps prime the system at key on, the fuel pressure rises to 40psi and then bleeds off. After turning the car off, the fuel pressure also bleeds off pretty quickly.

I dont know what else it could be. Can anyone with any knowledge about this help? thanks!

[mb3000]

Shooting in the dark here, but what are you using as your return fuel line?

[n2nsanity]

mine's pretty loud too. loudest fuel pump ive ever heard in my life lol
i thought something was broken for a while

you checked the return line and regulator?

[futurevr4man]

fuel pressure bleeding off is very normal on these cars.

start tracing your fuel lines. you might be right on a pump being bad

[DuTTch]

what pumps are u running?

[20G_VR4]

twin walbros. one new, one used. im using the stock feed line as the return. I have no leaks whatsoever under the car. I thoroughly checked it. Im almost positive its that used pump. Ill be swapping it out for a new one tonight and hopefully be able to build some boost.

[DuTTch]

check your orings, make sure they seated right

[20G_VR4]

will do. ill let you know what happens tonight.

[20G_VR4]

Cleaned out the gas tank and was running awesome on 10psi with a 10.5 afr and 14 degrees of timing. I even accidentally overboosted once to 17.8psi @ 4800rpm and it ran like a raped ape with afrs and timing still the same. Eventually, I was tuning at 10psi in 3rd gear and about two seconds after I let off and started coasting I heard a metal clanking noise and the motor died. Spun bearing mod.

Towed it back to marks house and I guess Im building the motor earlier than I expected...

We pulled the heads and everything looked fine. 150+ psi compression on all cylinders. Timing was perfect. Turbos were seized. Mark took them apart and found bearing material in them.

[futurevr4man]

i cannot believe that! DANG! thats sucks! first night out and all...

im gonna go ahead and re-say that i have that built 3.1L bout to come out of the car. 12,000ish miles and it works perfect.

[vr3.9]

Really sad to hear this. Do you have any idea what the cause was. Dented oil pan? Just general wear finally pushed to hard?

[n2nsanity]

wow, that sucks. looked like everything was going great too
at least you got to enjoy it for a little while

[20G_VR4]

oil pan was fine and we completely cleaned it out and made it look brand new before we put the car together. I think it might have been general wear and we just finally gave it more than it could handle.

[j2k4]

Really tough break.

Hope your wallet is fully-charged.

[CoreyB]

Sorry to hear that. Spun bearing mod sucks balls.

[Sin'sVr4]

damn that sucks man. thats why i redid my bottom end with forged internals. gl man. hope you get it all sorted out

Damn. You didn't inspect the bearings when the pan was off? This was an original block?

[markoverclock]

original block with 109k. Didnt pull caps or mains to inspect:shake2:

[markoverclock]

mine's pretty loud too. loudest fuel pump ive ever heard in my life lol
i thought something was broken for a while

you checked the return line and regulator?


After we got the bad tank cleaned out we could no longer hear them, and help good pressure after shut off.

[NOMIEZVR4]

oh man...what a bummer...:(

Ive been there and done that...not fun..

[green-lantern]

Oh damn! That sucks!

For some reason I've missed this thread and just read it all. It was almost heartbreaking to read the SB part. :( Sorry bud, clean the parts well and get a new oil cooler.

[TajMan]

dang
good work though mr. fabricator, you're like my hero
some day I'll do things that nice

[20G_VR4]

Ray Pampena's Stage III 6G72 came in last Wednesday, and I'm starting to tear into her tonight to remove the blown block. I'll be cleaning out all the entire oil system and replacing everything that I can (i.e. oil cooler, lifters, etc). Hopefully, I'll have her running again within the next few weeks. Unfortunately, I'll only be able to work on her on Sundays :(

[keo92stealth]

how did u blow it up? sorry if u already stated. i didnt read the thread.

[futurevr4man]

spun bearing keo.

still interested in results. congrats on the pampena motor. he is the man!

[markoverclock]

Ill be doin some work on it after work, probally mostly cleaning parts to transfer them onto the new engine. She should be done in a few weeks at most. First thing got to get the old engine out. :p And order some of those nice spal fans, lol. Cant have the summer heat in Tx fighting us. I have to tune with A.C. lol.

[keo92stealth]

that sucks but atleast you have the pampena shortblock. hands down probably the best 3l out there. im very interested as well to see how it performs when finished!

[mb3000]

Mark, what would you charge for a set of headers like that?

[markoverclock]

Mark, what would you charge for a set of headers like that?

Those werent cheap collectors, they are SPD collectors at $230 each. I have since made a jig to make full collectors, so i would say to make some like that again, your looking at about $500 each for some one offs. also the v-bands are male and female. My new single kit will have a equal length header design in software then made on the car, these ones are very very close that you see in his car.

I was working on turbos tonight they should be done rebuilt by tomorrow.

[mb3000]

Dear god that's practicly stealing!

Can you divulge any more details on the single kit?

[20G_VR4]

The car is almost buttoned up. Just need to get the glove box back in and she's all ready. Did a decent tune to wastegate pressure (~8.5psi), with no knock and almost no timing, and she's already quite the car.

I can't give markoverclock enough credit for everything he has done. He really knows these cars inside and out.

I'll try to get some pics up soon.

[J. Fast]

Congrats on the build. Some nice looking work there!

[FeaRpb]

I hope to see this car, you and Mark at the Texas Gathering.

[20G_VR4]

I hope to attend, but I'm constantly haunted by small problems with this car. We replaced a boot on a spark plug wire because the spark burned a hole through the side, then all of a sudden the dash and tail lights start going out. We have taken apart the dash, removed the radio, disconnected the active aero, etc, etc, done everything we could, and it still keeps blowing the tail light fuse. Am I missing something?

Also, for some reason, both my coolant hard pipes are leaking at the water necks through the couplers (stock coolant hoses cut to make couplers), so I may have to get some new couplers.

[n2nsanity]

A while back I had a problem with the tail light fuse repeatedly blowing. It ended up being my rear defroster wire shorting out somehow. I think it's a green wire that runs from the hatch, up the passenger side floor. I don't remember how I figured this out, but I either disconnected the rear defroster at the glass or yanked the whole wire out.

Ugh, that sounds like a nightmare. Good luck tracking everything down. At least come dyno on Nov 10th :)

[markoverclock]

depends on what i have going on. and if i got the cash i would like to go. but uncertain right now on the funds asspect.

yah we disconnected it in the rear, but didnt disconnect it under the floorboards. Were exactly is that wire ran and where does it end up at so we could just disconnect it at a plug or something up front.

[markoverclock]

and we still need to replace the one of the fans with a spal fan before it goes on any trips.

When you have time to put my car back together, money will fall into your hands, lol !

lol, waiting on machine shop, supra had to get new pistons and machine block. prolly like 2-3 weeks out guesstimating

[Marshall Taylor]

Mark,

Thanks for the update. My garage queen (car) needs your magic touch.

[ja3gt]

Heard a little about this, this weekend anything new?
