I am looking to upgrade my turbo to something that has a higher power output than the stock RB20 turbo. I track/AutoX/Solosprint my car, so I am trying to find the best turbo for that application.
I am aiming for 200-220rwkw, but don't want it to hit full boost (.8-1 bar) after 3500rpm. Currently my car hits 1 bar at 2900, with an FMIC and cat back 3'' exhaust.
I drove a GTR at autoX yesterday which is fully built with gt2860's and an R34 N1 block. The spool comes on WAY to late to even be competitive at the track.
So basically I am looking for the best trade-off between quick spool and power output. Obviously I will have supporting fuel/exhuast/ecu/internal mods for the turbo. I am just looking for turbo information, nothing else.
The one turbo that stands out atm is the HKS Gt2530 due to it's "bolt-on" feature and which apparently can hit 210ish rwkw. Does anyone run this turbo, and what kind of spool am I looking at with one.
Are there any other suggestions for an internally gated turbo for an RB20DET (HCR32). If I HAVE to I can purchase a new manifold, but if it's bolt on all the better.
Thanks!
