my friend plans on building a block and boosting it. he says he wants

b20b1with stock type r head
8.9:1 weisco
eagle rods
ram horn mani with a gt32
and e85

what kind of power could be made on this set up?

 

depends on the injectors and fuel system.
need more specifics.

 

1000cc injectors and a 1000 fuel pump

 

Six.

 

Which GT32?? There are a few variations of them so more info would really help. I know i ran an STC built GT3255b and made some pretty good power. If its a Shodan turbo, i'm sure you'll have no problem pushin past 400whp. I'd be worried about those stock B20 sleeves...

I think it's quite generous.

What is a 1000 fuel pump?

 

the block is aebs sleeved

the turbo is a stc gt3251e

 

you are never going to find a straight answer. go to a dyno or look up other peoples builds.

 

PM TheShodan and see if he can give you an idea. He should have records of the dyno testing for that turbo

 

why not a gt35r, seen lots of good dyno sheets on the net.

price, the GT32 is journal bearing.

and to answer the OP's question you should be able to max out the turbo with this setup

 

Who'd you get the turbo from? Your screen name doesn't seem familiar.

 

ill ask my friend.

so were looking at around 600hp on E?

 

i'm guessing 156whp.. but only if it has madd vtec yo

Not on the GT3251...you're looking around 450whp max.

Cool. Just curious. The hammer was meant for me btw not the OP.

 

450WHP no i should be able to make more than that.

 

No. This turbo's capability is no more than about 400whp maximum. If it is truly a GT3251, it will do only that. That turbo was not designed for top end power, only as a low rpm midrange power setup. Putting a "ramhorn" w/ that static compression will only create disappointment if it is truly a GT3251.

Limitations are limitations. Once a turbo reaches its peak there is nothing you can do but get a bigger turbo.

 

ugghhh....Im so sick of these "how much power will this make" threads....I wish people would just listen.....you design your setup around how much power you want to make, not the other way around

Nope...definitely not. The GT3251 is basically a trimmed down 57 trim. It was meant, as TheShodan stated, for quick spool and midrange power. I had another variant of it, the GT3255b, which is a little more geared toward the top end, but still a tad smaller than the 57trim. With the power it made on my setup at 10.5psi, i would have only guessed it to be capable of 435-445whp. Since your turbo is smaller, you will have a hard time breaking 415-425whp. What you need to do is snag a Borg Warner S256. That way you'll be set to make 500+whp. If you need more room, look into the S362.

 

well that sucks i dunno if i wanna go with a bw turbo i like my garrett alot
