Just use the rb25det but don't build it just replace with the other 2 you have spare if it goes bang haha

why rev's?

[O2 Autosports]

I'm guessing cause it sounds cool.

Rb 20 crank in 25 block with gtr or stronger rods and custom forgies would rev hard and hold together.

[dreadr31]

Makes the gears abit longer and i love limeter

Normal 300kw 25 is getting abit boring

Thinking of working neo24 for its soild head with 20 crank and rods, low comp, porting

Not sure what cams valve springs to use or type hmmm

[O2 Autosports]

sounds good. some 290 degree cams maybe?

[The Dan]

You'd be mad to put in anything less than 320 degree

a few mm off the crank isnt going to make it rev like a sport bike.

what about oil control + the 11ty billion other problems that will surface

[R31Nismoid]

Ye there is some serious investment that needs to go into the head.

Just a set of springs really isn't going to cut it for extended 9000rpm+

Well 290 degree cams give you 1000rpm response over any other choice according to some around here, so they should be the first items purchased!

espesially is they have JUN or HKS stamped on them..

No other 290deg cams will do it though

Yer just wanting to see people experience they have had im off to japan end of the month thinking of going to tomei and getting a shoping list happning

[Luke_GTS-T]

buy an s2000?

[dreadr31]

Proply go a rotary over that but i dont have a shed full of honda or mazda junk haha

Want good power at high rpm

[JustinP]

Hahaha.... But seriously you want revs and you don't care about power or response... Buy a Honda with vtec yo, or for even more fun, go an give yourself a tax audit.

[dreadr31]

Well i want 300kw@high rpm i use my 32 for comption drifting so a s2000 is not what im looking for haha

[zebra]

standard RB20 rods, 400hp and 10k rpm...please post video of the 1st full power run

[dreadr31]

Yer will do just need more info

[The Bogan]

Or use the money you will need to spend on it rev to 9k for any extended period without lunching itself on 5 stock motors with boltons like most skidders do.

Lunch a motor, swap in a new one, simple.

Do that.

[dreadr31]

Yer thats what i do

But it not what i should do its what i want to do

and i want a crazy reven rb makes noise

[N1GTR]

The most insane RB track car I've ever heard, as well as a large amount of guys from the drifting in melbourne was powered by a stock RB25.

Of course if it had 290 degree cams and a smaller stroke crank with custom rods and pistons it would've been better
