Even look for something like a HKS 2530, will be super responsive still and give you the power your after.
Probably wont need larger injector's, deffinatley go a larger front mount.
Dont forget to, that with big 35"s you will show a lower figure on the dyno, changing to smaller tyres to get it tuned will result in the 200rwkw easier.
Last option is more expensive but try and get a RB30 bottom end.
