Upgrade an rb25neo

[Tekitsune]

Hello, just just bought an 1999 enr34 with a stock rb25neo and I'm looking to upgrade the engine to 500whp I know some basic things but wondering if there are things I'll need to do to upgrade the stock block and all the bits and pieces to achieve this.

Although the best way will be to put in an LS7. Why anyone would mess with an RB when they live in the country where the LS7 was built is a mystery that can never be solved.

I frequently tell people interested in buying a GTR to either pick a 996 Turbo or E92 335i 6MT. Either one is close enough to being what you wanted from a GTR while being much, much cheaper. I just have brain damage and had to have one anyways.

They aren't, but it depends on what interests you about an R32-R34. If it's the front engine I6 turbo that tunes well with a manual transmission an E92 335i 6MT is so incredibly cheap. You can get a super clean one for 20-25k USD tops. Put an LSD in it, tune it, have fun with it. If it's the general idea of AWD + turbo and a manual transmission the 996 Turbo is absolutely much more expensive, it's less practical but it's also basically a complete track-ready car from the factory. At least the Mezger doesn't have heaps of oil control issues. And in the US the 996 Turbo and R33 GTR are roughly the same price these days. 996 maybe a bit more now that the hype has abated for old Skylines here.
