I current am debating which turbo to change to i currently have a g35r with 1000cc precision injectors. But since i caged my Integra now im looking to making more power and making it more of a race car. My manifold is a T3 flange so im looking at doing a billet 67mm turbo. what kind of power numbers have you guys seen and what ets on a B series.

what injectors would i need to use and will my precision 750hp intercooler be big enough? and will one single Tial 44mm wastegate be enough or should i need two?

Or i can ditch the t3 manifold and do a t4and start fresh and go for the s372.

it sees some street duty but i currently dont have a chute or dogbox tranny.

let me know what you guys think or what you have seen from other peoples builds

 

i think it ultimately comes down to what type of class you are trying to race in...67mm or 72mm class?

Exactly.

The billet 6765 will make ~850-900whp, the S372 can make around 950-1000whp.

 

I would do the 67. Either way you'll need either some ID1000's at 100psi base or some 2000cc injectors if you want some big power. Since it sees a fair amount of street time I'd say go with the dual bosch pumps or the walbro/bosch setup. But like already mentioned, it all comes down to what class you want to run and what your power goals are.

 

I have dual walbros now. I seen those 2000cc injectors they look good but spendy. I think i might need a 60mm wastegate as well? What are people getting out of b series with that billet 6765 turbo ball bearing.

 

I was going down the same road as you.

With my dsm, I decided to go with the S372 route, on a divided T4 manifold with twin 44's. My car is built as an 'outlaw' car, but Im not going to be running 8s, and we don't have that class up here anyways, and I doubt I will drive down to the US to compete very often, so I just built it to be as fast as possible.

You can't go wrong either way, there both great turbo's. The PTE turbo will be more money (BB), but you can stay T3, with the T4 you will need another manifold/wastegate etc, but you can sell your old manifold. So it might end up being about the same price difference.

Goodluck!

 

yeah the bb 6765 is 1700 and the s372 in 1100 but my manifold is good and i can pull my motor without taking the turbo off. my car is still a street/strip car so i dont want to slow of a spool. but i know for the buck if i was going to build an all out race car and had a strong tranny then i would just go s372 and go for low 9s and 165mph times

 

6765, id1000s and leave your wg and downpipe how they are. make it a simple change not a crazy one

 

well i dont want to put it on a dyno and find out i need more wastegate then have to retune and cost me more money. i think i might do the 2000s and go with e85 what do you think

 

on high boost you won't need more wastegate. if its a street/strip car, 67mm all the way, chances are you won't be happy with a s372 in that case.
