I have an ultimate racing bottom mount log manifold. I was wondering if anyone knows if a Precision 6262 JB turbo will fit or not. I know it would be recommended that I just get an ELT or SW but I don't feel like spending all that much on my daily but want around 450-500 (for now-more later) I know that my manifold is probably what's holding me back more so than my turbo, but it can always be changed later.

Thanks!

 

Not sure of fitment but i know with my pfab log and 6262 .82 ar, i made 436hp and 301 fl lbs. now i have a allen built short block and hope to make 500. i will say this there is nothing wrong with a log manifold or JB turbo. my honest opinion it will outlast all other stuff and still make awesome power. now precision im not sure about. but JB is better then BB for a daily. just remember dont set a hp goal or figure to reach just set a reliable goal and be happy with what you have!! good luck with everything.

 

The 6262 will fit your current manifold (just be sure to get the t3 exhaust housing with whatever discharge you have on your current turbo). What compressor cover are you running currently?

 

So many contradictions in that post.

"Hey, I drive this every day, but I want to make sure I can make more than 2x the power it came with"

 

Thanks! I appreciate the advice. Hoping to hit at least 450 on pump gas but anything more than now I'll be happy with.

Hm, not too adept in turbos but I'm guessing the compressor cover refers to the .63 a/r. Was looking into a .82 6262, but I guess if I have to get the .63 it can't be helped. Thanks for your input!


This post was pointless, you provided no help whatsoever, but since you'd like to troll, I will clarify for you.
The S2000 is daily driven for now until I complete my full 2JZ-GTE swap in my N/A supra. Then I will daily drive the supra and go for as much power as I can on the S2000. Then if ever has an engine failure; simply rotate, build the supra and get another daily.
Thank you for nothing, have a nice day.

 

.63 a/r (a/r is the area/radius ratio) is a common exhaust size. What size is your compressors inlet? 3" is common with the 'E' covers (which typically have a .60 a/r and typically have a 2" discharge (outlet)); 4" inlet is common with the 'SP' covers (typically have a .70 a/r and a 2.5" discharge (outlet))

To answer your question, you could go with either the .63 or .82 exhaust side (among other options).

 

How to calculate the area radius ratio (a/r):

 

What kind of spool up were you getting out of that setup? when were u making peak torque?

 

Peak boost at 14.5psi was between 5-6k and peak torque at 7k rpm. That was with an f22 though. I feel like the f20 would have outperformed the f22 and been better overall.

 

Thanks, I've learned something new today, I'm going to try that out next time I head to the shop that my car is at. Haha.
