IIRC the Precision 91.5 can be had with a F or G wheel. The F wheel is 111mm turbine(IIRC) and the G wheel is a 130mm turbine. IIRC the S500 91 has a 109mm turbine.

I would use the S591, or the 91.5 with the F wheel.

both will make more than the stock heads can hold without pushing.

dragrex

so pretty much the same crap if you look at it as.... 111mm vs 109mm
not much difference?

dragrex

lol yeah i hear you there

dragrex

dose anyone think that my motor is to big for a 88mm turbo?

No, not for a Large Frame 88mm turbo. The PTE X275 turbo would be perfect as would the S500 88. The S500 88 91 and 94 are all built on the same chassis just different size compressor wheels.

Also I did some research on this, I could not find one place that specified the actual mm size for a F trim or a G trim turbine. I might be wrong in thinking this, but maybe the F trim is a 98mm turbine and the G trim is a 111mm UNLESS you go into the thumper chassis turbo's that use the F trim or G trim and then they are either 111mm or 130mm. I've also heard from some that the only difference in the F and G is the exducer mm size.

Jose, or Josh if you see this can you clarify?

Thanks for all your help on this first off!!!!
I'm kind of wanting to stay around 2,000 for the turbo and I see them 275 88mm turbos are like 3600 bucks!!! I see some people like this guy with a s88 ( not sure if it's the 488 or the 588) running low 9's at what I would call low boost and his turbo he says in his for sale ad is a -S88 AirWerks Turbo – T6 flange, 1.3 A/R here is his post https://ls1tech.com/forums/vehicle-c...camaro-ss.html let me know what you think

That is the S500 chassis turbo. Should have the 109mm turbine. Again I'd like for Jose at Forced Inductions or Josh@kyturbo to confirm this, but I think that's right.

FWIW a local X275 racer, he has a 357 C.I." Ford Motor that Pete Harrell used in his SSO car years ago. They refreshed it and put it in chad's fart (ford+dart=fart) with a borg warner S500 but it had the old cover with the 98mm turbine wheel. He went 4.99@145 with that turbo. He has since switched to the PTE X275 turbo and has gone as fast as 4.93@149 IIRC. 3450 pound car. Should run 7.50's in the 1/4. I'd say with half the boost he runs you should be able to run 8.90's if not mid 8's with a good enough short time.

Here is the thread I was looking for where Jose from Forced Inductions explains all the differences in the S500 GT-55 and PTE F and G trim turbine wheels.

I've been impressed with the BW stuff. I ran an 82mm a few times and it is impressive.

I don't think you can go wrong with either, but as someone else said, heads are going to be your problem.

I'm thinking the bw 88 for my car also

dragrex

At what psi/boost level can I expect to push water? I understand it can push water een at low boost but what are people usually getting up to? Also where is a place that sells the bw588 that can offer a great price and line me up with the correct a/r???

konceptracin

I think you should buy the 88 and the 91 and let me know what works best for you lol

dragrex

TTT any turbo experts?

I'm pretty sure a s88 is a 400 based unit, I think they call it a s400hp88 for clarification now. I believe its a borg warner turbine with a garret based compressor wheel.

s88 does not equal S500SX4-88, there is a s500-88 now, but the old s88 is 400 based. I believe this is why the names changed to cut down the confusion. the link that the op provided is a turbo that was built in 07-08. Forced inductions were the only ones I know of selling the 500 series back then (older version) under the FIX name. the turbo you linked to came out late 2011.

Yeah I'm confused now forshure..... why the he'll do they need 100000000 "88mm turbos". Lol
