AWD conversion/engine build

In for the elaboration!

yeah I might be a little high. Maybe 250 is more likely. I plan on adding a walbro and running 13 psi this winter. Maybe a Sure-Win Exhaust since they are out there so cheap now. That should get closer to 300whp.

What do you think about a cutout? I drive 15k/yr DDing the VR4 and I like the quiet/non droning sound on the highway, but I want to help out the power. I thought about a DP and E cutout?

your build list is basically what I want, minus the built engine/trans, Emanage, and 19T's (substitute Fresh long block/stock trans/braced Xfer, 16T's, Blow Thru MAFT/SAFC2)

END thread jack. Maybe Ill PM you and not clutter up your thread.

I cant wait to AWD my stealth. I need to find someone who can weld :P

Sorry I haven't elaborated sooner. The custom lines are just way smaller than stock. There is usually a good bit of air in the stock lines while in the custom ones there isn't. I think the oil is more forced out of the smaller lines so when pressure builds up in the crankcase it can put too much pressure on the turbo seals. The stock ones have a bunch of room in them so if you get some gases back through them the air can compress and if it pushes through the seals it isn't a line full of oil it's just some air. This isn't a technical explanation but just some of the issues I've been checking into. Ether way they are WAY smaller so it can't be a good thing.

Mike VR3.9 has one and he seems to like it a lot. I think he had some good HP numbers to back it up also.

Just thought I’d give a little update on my car. The machine shop didn’t seat the VSS well enough so some started coming off the guide and causing the car to smoke. So I had to replace them and while I was at it I did some other stuff like new O2 sensors and installed the new EBC/scan tool. Got the car running great but I guess I got in too big of a hurry and didn’t tighten the timing tensioner pulley down well enough. I started hearing a noise coming from the engine, pulled over and popped the hood. Since I can’t run timing covers I could see the belt flopping around so shut it down immediately. It was pretty disheartening to say the least.

Saturday I got the tension back on the belt and rotated it around to TDC. The rear bank wasn’t off by much if any at all but the front was pretty far off (intake cam). Sunday I set the timing back correctly and compression test was all 150-160 except cylinder #3 was down to 125. Did a leak down test and could hear air coming from the intake. So pulled the head and tested the valves via diesel fuel. Looks like I got pretty lucky and only bent one valve. I thought I’d at least have 2 bent but nope, just one. I was able to take a valve from a spare head and it sealed better than the valves in the cyl that had 160 in the compression check. I was pretty happy about that!

I guess all and all I was pretty lucky considering I got careless and in a hurry with the timing belt. I’m not going to make that mistake again. I could have got away with just setting the timing and running it but 125 was just too far off for my comfort and I do plan to race the car. I might be able to have it back together today or tomorrow.

Nice catch, could have been devastating.

yes! Almost every time I've heard of this happening it usually means heads being rebuilt at the least. I know for the most part running timing belt covers is a good idea but in this case I knew exactly what it was at 1st glance and shut it off. I'm lucky as hell to have only one valve bent.

I can't wait to see this build in person again. I'm glad the timing issue didn't cause any major engine damage. I'd love to run without covers myself just for the look of it, but I fear small rocks and stuff like that. I guess in your case since you can't, it was indeed a life (motor) saver!

Wow, you came a long way from asking me conversion questions, while we were in the little cramped garage drinking beer and talking about hotwings. I'm sad I never got to take a ride with the N/A turboed engine, I always imagined it being a bit torquey. The digital display on the RPM indicator is pretty trick, I love that front I/C pipe too, my factory peice doesn't fit correctly with my 2 core. I have to figure out my car now so I can come see the car paul.

geez paul, how many places did you whore this thread?
