bullseye turbo selection suggestions

[bobob729]

well i'm looking into buyin a bullseye turbo for the rb25 and was wondering if anyone has any suggestions? i want to be able to spool fully by 3800 and be able to make about 450 whp right now and room to go higherany suggestions we mapped it out on the compressor map and the s258 looks pretty decent but looking for other feed back from other people.thanks matt

the Borg Warner S256 would be a great turbo for the power goals that you seek and should be able to flow enough air to have you in full boost by 3800-4000 RPM's. Many honda's run this turbo in street apps for the quick spooling characteristics.

I have an S362 in a twin scroll setup that should be finished in about a week.

If it doesn't spool quick enough for me then I might have to go a tad smaller. We shall see how it does.

well please let me know my deciding factor is the s258 or s362 so i would really like to know how the s362 spools

anybody else i think i'm gonna go with the s259 just cause of how it spools but i would really like to know how the s362 spools anybody else?

I'm still not done with my setup....while my car was up in the air on a hydraulic car lift...the lift broke. So my main concern was getting it down safely. But soon...

In the meantime, take a look at this thread:

This guy has an S362, but, he's having some issues with his setup. Once ironed out it should RIP.

FWIW I think the S258 is probably a great turbo for your plans. Quick spooling and can still support about 550whp (100 more than your initial goal). It is much like a 3076r (which I am also a fan of) but slightly larger.

As a side note are you dead set on the BW turbos? Otherwise the new PTE stuff also looks really good.

D'oh! Hopefully you get it down safely! </threadjack>

Yes, thank god. We got it down last night. Was a PITA.

I don't care if the lift gets fixed...I'm finishing the rest of the work with a floor jack on the GROUND!

honestly yes i'm set on the bullseye turbos just for the fact that i can get them cheap from a dealer here in town so......that and they spool faster than the gt30r so....i had a precision on my 300zx and honestly it's a good turbo but the seals are already bad and it's barely over a year old and half the year it wasn't on the car so......that and it had shaft play when i recieved it brand new(they said this was normal)
