Re: What does it take? Do the headers have problems with stress cracks?

Re: What does it take? Man that gives me a lot of help... was that on the new motor or the stock? **edit: I see that was stock motor no nitrous... what kind of setup were you running?

What does it take to make approx. 400 hp to the wheels in a Sy/Ty? Also, what about how fast would a 400hp ty run in the quarter?

Who has the highest horsepower... Single Turbo Built v6 Sy or Ty? also, what kind of quarter mile times did it run? -Nick

Re: Gt35r? Eric... I just want to make sure I understand this correctly. If I have a 12psi actuator on the turbo and ran a manual boost controller... the max boost would be 24psi correct? Nick

Re: Gt35r? thanks man.... hopefully I can get this project underway soon!

Where can I pick up a GT35R with the Sy/Ty housings? I think this is the turbo I have finally decided on.... also can I get different wastegate springs for it?

Re: Stock boost? Okay I have been thinking about it... I know the stock 17c will be fine for my application FOR NOW, but would I be better off just putting the GT35R on it from the get go? I have been thinking about keeping the boost real low.... but seing that my weak points are the cast...

Re: Stock boost? Yeah I had to go back and edit my last post.... had something else on my mind. So what could I do to keep the max boost at 7-9 psi? Boost controller and a new wastegate spring?

Re: Stock boost? Well, since my ECM doesn't have a boost controller in it.... I think I am going to need an aftermarket boost control.... maybe something digital. If I ran no boost control and relied on the stock wastegate... what would be the max boost?

Re: Stock boost? The best part about the tuning is that the 01+ S-Series have a LS1 style ECM. LS1Edit works on my truck.... so when I get it all running I got a guy here locally that tunes for the GM Performance division. I'd like to keep the boost at 8 psi for now, I still need to figure...

Re: Stock boost? The MAF shouldn't be too much of a problem. I mean guys are running 12lbs with a s/c on the stock MAF. Getting fuel into it is going to be the hardest obsticle. Our stock manifolds only accomodate 19/hr injectors just like the 5.7 L98 Vortec motors. I have found a MPFI...

Re: Stock boost? New lower compression forged pistons are planned..... L35 heads flow better.. L35 rods are pretty damn beefy....as for a cam I am getting one from CompCams so I can get rid of the valve overlap.... since the turbos seem to like it better. so the only other area that needs...

Re: Stock boost? There is no way I would even be able to fuel 14.7 with the stock 19lb/hr injectors. To me the weakest part right now is going to be the 4L60-E. Whats the difference between the Sy/Ty block and my L35 block?

Re: Stock boost? See I am getting ready to drop a turbo setup on my 2003 Blazer Xtreme. To start out... I would like to limit the boost at 7-8 psi until I get my new intake manifold to upgrade the injectors (Mercruiser MPFI intake). Everyone keeps telling me to get the next turbo up for a...

Re: Stock boost? Is this 14.7 psi with or without a boost controller?

Forgive me for being a noob on this.... but what is the stock max boost (unmodified SyTy from factory)? Also, what would be the next step up on the turbo, if I wanted to go larger?
