Garrett turbo ideas for my gs-r...help!
I'm currently in the process of a turbo project for my gs-r b18c1 with a c5 block...I'm deffinitly getting a Garrett turbo I'm just torn between wut model I actually want...Im shooting for 350-375 whp with a very fast spool an incredible reliability...I plan on spending anywhere between 1300-1500 just for the turbo...I'm torn between two models in particular one being the gt3037r aka "gt30r" and the gt3076r...I'm also open for any other suggestions and will specify the internals im using if you guys are interested...

Any help is appreciated but please no b.s

Thanks
Josh

 

disco potatoez

 

Lol wut a DORK!

 

whats a fast spool for you?

 

think im kidding?

 

The turbo might be at a stretch for 375, but people seem to make 300 easy on them. Spool is "quick"

 

no your right

a gt28r series like a gt2860-60rs-and71r

fast spool within the 350hp range

 

the two turbochargers 3037r and 3076r are one in the same just a different name. the "disco potato" referenced above is a gt28rs, its possible but would be hard pressed to make 375whp. the gt3076r would be an excellent choice if you want 375whp now and room to grow later.

 

ok question for the post above me... on spoolinerformance.com the gt3037r "gt30r" claims to be "faster spooling" then the 76r and "very good for 4 cyl aplications"... u say theyre basicly ther same but you dont think the 37r has a slight advantage by any means?

also looking at ar ratings i know the science behind it but for a b18c which would b the best rating for someone whos shooting only for 350-375 with quick boost response? .63?

 

smaller AR is going to give you more down low and better response, bigger AR is geared more for top end.

 

i understand that but do you think the .63 ar rating will be almost too small and when it comes to topp[ end ill end up losing power?..keep in mind im only looking for 350-375

 

no not at all, .63 seems to be a very common ar.

 

i took a quick look at spoolin's website and never saw them say the 3037 spools faster. if they said it spooled faster they would be lying.

 

i apalogize i did not mean to say i seen that quote on spoolinperformance.com i mean to say i was told that...you think the 76r is faster?

 

 

apparently you arent getting it they arent 2 different turbochargers. it is the same turbocharger with 2 names.

 

I'm using a GT3082R with a mitsubishi big 16g exhaust housing. It spools right around 3000-3100 rpms for me and i'm at full boost around 3900-4000rpms. I'm running a built poorman's at 320 whp with no loss of boost at the top.
