Re: up grade Nissan RB30E 3.0L Straight Six
Razor GTR is pretty much on the money. The RB 30 was used both in the commodores and many 31 skylines. It is not probably as strong as the 26 but is still a strong bottom end and can handle some serious power especially with good pistons etc. I know a 33 GTR with a Rb30 block and 26 head that has over 450rwkw and running a single custom turbo and pulls hard from 4000rpm to 9500rpm. However this is a very expensive upgrade. If you are looking to turbo the engine try to pick up a cheap one already with a Turbo set up on it and look to upgrade Turbos stc but just don't go too full on. I am unsure how the comp was dropped in the Turbo motors but would think it was to do with head gaskets etc.
