according to Precision the setup has been done before, the backpressure isnt that big an issue and they actually recommended the T4. So I dunno. I have N20 to get the job done however I get there, It WILL make 4 digits at the wheels. No new pics yet, nothing too pic worthy, Im so broke Its on hold and Im buying parts piece by piece...
On a 370ci engine a PT88 at 21 psi was making 54psi backpressure. That was at 878rwhp..... On a 408, probably will be near 62-65psi.

****, I called precision again, and this time talked to a different person on the phone, and he seemed pretty pissed that someone sold me this turbo, got my phone number, and said he would call me back.....this is NOT good.... I just did all this damn fabrication to make the damn thing fit and its not even going to work for me?! I dont even know if I can fit anything bigger in there! Ill have to make a whole new DP, cut the T4 flange off, and weld on my T6 flange, then how do I know the hot side parts will even be big enough or not?! they are only 1 5/8" primaries and 2" crossover pipe and collectors. ........ I should just pull the 355 LT1 out of my Z28 and put it in there! lol jk

Well I talked to someone at FI... (yes dont gripe too much Dr. Turbo lol 
jk)
looked at a few pics, I think running a FI-9155 would be the best choice.. because what Im looking at now after re-educating myself (I dont know **** about turbos!!) is either an 850rwhp motor with head gasket issues.... OR a free breathing 1300rwhp motor with no issues... the choice is pretty aparent! looks like Im back to breaking out the lincoln 175!

Wow I never even heard of Ohio Forced Inductions untill now..... all I can say is.... Im going to be sick! exactly what I needed for the same price I paid for the PTK pile of garbage.. and its made with better materials, I could have just bolted it on and made 1300 rwhp on this 402.

well all I can do is run it how it is with the lil PT88 and once I get back to iraq ill order a big stuff 3, and an Ohio Forced Inductions kit fitted for an FI-9155 with 5" downpipe. Then toss in a good 'glide and converter and she should really ******* honk for a street car! It has long been a dream to run 8s with a street legal car, and for a 22 year old to build one on a soldiers budget, well Im proud of myself lol.
