Rb25 makes 500hp

[GT 1]

Now that i have ur attention. I have a fully rebuilt Rb25 most of which has been modifed excluding the standard cams. im looking to achieve that 500hp figure. Most of everything has been dun to the motor, i kno its vague, but has any1 hit the 500 hp mark atw? what camshafts are adviseable if i don't want to modify anything else (ie cylinder head clearance machining, up-rated valve springs, special retainers, solid lifter kit)?

If it does hit 500hp atw ... u all will definitely be detailed

thanks

500hp = 373kW

At the wheels.

It's been done on a 25 but it's up there.

You would prob. need something higher up like Tomei 264? Hopefully not 272...

Well i have made 421rwhp with a leaking manifold on pump fuel. Rb25 with standard Det cams. I would love to see the magical 500hp. Good luck with it.

i think he means 500 engine hp

there are a few who have got close, and gone beyond that.

500hp oout of 2.5 is a good effort.

wat turbo set-up ?

that's the most important factor.

I'm thinking of going 30(31) bottom end

it's just easier

Which part was complicated about 500 hp atw, inasnt? I think that means at the wheels, mate

500rwhp is absolutey nuts, u'd need to tub the rear just to get traction

[BU5TER]

Why's that ben yeah its not great in the wet but you'd be suprised what semi slick tyres and throttle controll can do for traction, its spins when you want it to hahaha

By nuts I meant... "dammmn im still having fun with only 270rwhp, double that would be out of this world"

Instead of those floor mats that say "Get in, sit down, shut up and hangon" you would need "Get in, sit down, shut up and i hope you brought a spare pair of undies"

the highest you can go up to i have been informed is 264 degrees of rotation, before you have to machine the head, get new lifters and valve springs

tomei cams don't make a 264 they only make 260 and 270 or 272 (don't quote me on this though)

hks have 256, 264

whats been mentioned to me is that the 264 cams will be enough to get ya 500hp, anything more then 264 is really for darg machines with 700+ hp

mmm I'm 99% sure I've got Tomei 264 cams

[APA]

i they pon cams or the other ones that tomei make?

coz i have read direct from the tomei website that for rb25det there is no listing of a 264 only 270 anyways if your correct then tomei and hks both have 264

adrian

mind you tomei definately do make 260 degree cams so maybe thats what u have?
