I would skip on that pos skunk2 IM for sure. Go with AMS, Magnus or JMF. Change out your cams for kelford 280 or gscS3's, get some 2150cc injectors and a 6262, 6266 or 40R.

 

I'm really happy with Buschur's turbo kit+6466 on my car. It made just over 700awhp on their dyno with ~E70 and without David leaning on it much.

That's running their 2.3RPM and head. Running just the BR ported stock IM and ported stock TB.

Cosworth M2 cams too, fwiw.

 

ive been hearing a lot of negatives and positives about the skunk 2. i know the biggest problems were fitment issues and cast problems. from what i heard these problems were fixed. Recently saw my buddies new one and seemed to fit perfect and looked like a real nice cast. and yea ill be swapping out the cams and also doing an e85 with the 2150's

 

If you get a skunk 2 get the stm works done to it

 

You've received some good advice thus far. LISTEN TO WHAT PEOPLE ARE TELLING YOU OR DON'T ASK FOR ADVICE

I will add mine as well.


DO
-Bigger cams are a NECESSITY! I would go with what ER calls GSC S2R's. I don't think Greg @ GSC 'lets' them call those cams that, but they are S2's with a little bonus. You especially need larger cams because of the bigger displacement.
-Double pumper is a must.
-FIC 2150, ID2000 or MAP2000 injectors



DON'T
-3794 - Way too big! So laggy = no fun
-I would avoid precision turbo's all together - stay with a modified Garrett.
-I'd personally ditch the cam gears. It's not necessary to tune the cam timing and they present the opportunity to fail and destroy the motor. Just IMO.
-Exedy twin. Ditch it now. Seriously. Read my build thread if you want to see how fast my fresh rebuilt started slipping. Don't upgrade to the triple. Upgrade to an 8 leg quartermaster street clutch
-Turbosmart e-boost - Don't do it. Get Ecu based boost control or a Hallman MBC
-Boomba throttle body - No, don't do it. They idle like crap, no matter what. Junk.



I would highly recommend the new CBRD LMP GT3584 kit. My car makes 683 on a mustang and should be about 770 on a dynojet based on conversion numbers and my injector duty cycle. If I added an intake manifold, it would almost certainly be well over 800whp on a dynojet.

I can explain any of my advice in greater detail if needed. Don't be stupid and avoid the advice of people with experience. Can't stress that enough.
