Hey all
I have a built rb30 bottom end running je pistons, spool rods and nitto pump.
The engine builder is in the process of changing from rb25de head running a t04z to a pretty much standard 26 head with only hks springs.
I also have the -9's, ces dumps and port matched standard 26 manifolds that where on the 26 head.
Now I'm after some advice or suggestions on my turbo options
I can either just use the -9's which will add a fair bit of complexity to it all or
have a new rb26 flange welded to my existing rb25de setup's manifold which is a very high quality jap stainless job or possibly weld, drill and face some tabs on the ex Mani to suit the 26's different pattern.
Motor is in a cefiro and I'm intending now for it to be track only and used for general thrashing, drifting, hill climbs and khana's and will be changing to e85 also.
I'm unsure if perhaps the -9''s will choke it up and be the limiting factor?
I'm running Nismo twin Plate clutch and standard rb25 box and don't really want to have to be replacing boxes all the time so power goal is around the 350-400kw mark
Cheers much
