hey everyone!

[IPD]

I'm collecting parts as things go on sale and I can snatch them cheap. Still haven't decided where I really want to go with the car. Probably a 3.1 with big td04s. I can't decide, all these sweet TD05 builds around right now. I wish there was a way I could use your strocker pistons, and if I want to go bigger later just install one of your cranks.

the pistons would be the same...assuming you already had a large enough bore. it's the rods/crank that are different.

I was under the assumption his stroker used a 75 crank and his special pistons and you could use any 72 rods of your choosing.

depends on which stroker you're talking about & how you wanted to do it. personally, if i was building the rest of the bottom-end, i wouldn't use stock pistons. and the 75 crank doesn't fit in a 72 block.

Sorry mis type on my cell phone. I meant 74 crank ray specially machines then uses his pistons. Here is a thread from the other site about it, I don't know if there is a thread here.3.5L 6G72 this is what im building for my car! -

I’ve had my car for well over ten years now, and the engine is getting a little tired. I think it’s time for a ground up rebuild. I’ve been reading up on what people have been doing with these platforms lately and I’m in total shock. The numbers people throw around these days are unheard of from when I did my first build. I’ve heard a lot of high numbers, but not much on the subject of longevity. I was thinking a Pampena Motorsports 6G72 3.5 liter stroker setup is a good start. My next question would be; what is the highest horsepower/torque target that I can shoot for on this setup and still expect modest reliability? Any advice or links on the subject would be welcomed.

The 3.5L 6G72 stroker uses special pistons with the piston pin moved closer to the top, stock sized 6G72 rods, and a custom cut/balanced 6G74 crank. I posted pics of my stroker pistons in the last few posts of that thread so you can see what I'm talking about. If I were to do it again I would probably just build a 6G74 3.5L motor because if anything happens to my stroker crank where it's not useable I'm out over $2k for another one all ready to go. The machine work and balancing is very expensive whereas a 6G74 crank is $900 new and much less used. On a 6G74 worst case scenario you would just need a new crank and balancing which wouldn't be as bad. It's $3749 vs $5749 between the two motors.

Ray made 1100AWHP on his 6G72 stroker motor without any problems as he checked the bearings multiple times to see what kind of abuse they were getting. That being said I wouldn't run one of those motors at that power level because if you make one tuning error it will destroy your bearings before you know it. Ray knows how to tune these cars so he never had a problem. If you had a billet crank instead I wouldn't be as worried since they're much more forgiving. I'm not too sure what the highest hp/tq it will reliably support since there's too many factors to consider to get an average for the stroker crank. 5-600AWHP would be a breeze. 700-800AWHP would be doable but you wouldn't have to worry so much about the motor as you would every other part on the car breaking/failing. Lol.

i plan to run 550-600awhp on 16g's with my 3.5L at ~20psi pure pump--for the rest of eternity.

Hey Ray, Man I don't have to tell you what's going on with my car. Hopefully you will get some free time to finish her up. Looking fwd to seeing what kind of power those GT 3076r's make on that 3.5L. Also I'll call you next week to talk about checking the transmission out to make sure the cluch will handle all the power.

TurboSinceBirth,

>Thanks for the reply. You have given me a lot to think about. Since I have some time before I start collecting parts, I am going to read up on some of the better builds on the forums. I just needed a target power range as a starting point to set my sights on.

Since I am having a kid in late Jan and was preparing for that, my cars been sitting. Everythings ready to go, just needs to be run down to you for a high load tune. My IPS tranny is coming and the plan was to send that over to you with the Supercar center diff and have the front diff swapped out for the one with the right gears in my tranny which is also a Kormex LSD. It might just be better to drop off the car and trans and have you do the tune and the tranny work together. I want to get the new tranny braced and ready for a little abuse. I am just sort of at a crossroads with the car where I really dont have time for it or to even joy ride it, but I still love the car and enjoyed it so much in the last 15 years its hard to give up. I am just afraid its goign to rust away under its cover now after being taken care of so well for so many years.
