Best Single Turbo Options For Built 2.6l Rb26

[underground]

Hey Everyone,

I was offered a Trust Single Turbo Manifold from a fellow forum member for an extremely reasonable price, and could not turn it down. Due to the fact we already have issues with the stock twins clearing the steering parts, I feel this should resolve these issues, and keep us from having to pull the motor everytime something goes wrong on the exhaust side of the car.

I'm now changing directions, and will be selling the twins.

I'd love to see 650-700whp out of this turbo, as I dont know my 240SX will take much more.

I can't put 400whp to the ground, so there is no need shooting for another 500-600whp on top of that. (Even though my block was built for it.)

Due to the fact I just blew half my turbo budget on a manifold, I will be sticking with something journal bearing to save cash. I can always upgrade later, but getting my car back on the street is my first priority.

I'd be curious to hear your suggestions.

is it the 3 bolt trust flange or a t3 / t4 flange?

It's been modified to a raised T4 divided flange, so that the previous owner could use his GT42R setup. It was on a R32 GTR Drag Car.

The wastegate piping was modified to fit a HKS 60mm wastegate.

Here are some photos for the manifold.

with the t4 flange you prob best with the t04z but that might be abit over the top for the powere your chasing?

Yes, I am leaning toward the T04Z myself.

you will want something that is twin scroll for sure. The T04Z doesnt work as well in a twin scroll as some of the GT wheels becuase it uses a P trim 11 blade turbine wheel (gt are 10 blade).

my advice is a twin scroll 40R housing on a 4088 non ball bearing... great bang for the buck. it will have much better response than the 66.5mm/84mm 72 lb/min t04z becuase its a lower trim (64.5mm/88mm)

Hum, what about the smaller GT42 non ball-bearing version?

How would that compare?
