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.

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

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+

sounds good. some 290 degree cams maybe?

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

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.

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

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.

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

    • Yep, the closest base tune available was for the GTT, I went with that and made all the logical changes I could find to convert it to Naturally Aspirated. It will rev fine in Neutral to redline but it will be cutting nearly 50% fuel the whole way.  If I let it tune the fuel map to start with that much less fuel it wont run right and has a hard time applying corrections.  These 50% cuts are with a fuel map already about half of what the GTT tune had.  I was having a whole lot of bogging when applying any throttle but seem to have fixed that for no load situations with very aggressive transient throttle settings. I made the corrections to my injectors with data I found for them online, FBCJC100 flowing 306cc.  I'll have to look to see if I can find the Cam section. I have the Bosch 4.9 from Haltech. My manifold pressure when watching it live is always in -5.9 psi/inHg
    • Hi My Tokico BM50 Brake master cylinder has a leak from the hole between the two outlets (M10x1) for brake pipes, I have attached a photo. Can anyone tell me what that hole is and what has failed to allow brake fluid to escape from it, I have looked on line and asked questions on UK forums but can not find the answer, if anyone can enlighten me I would be most grateful.
    • It will be a software setting. I don't believe many on here ever used AEM. And they're now a discontinued product,that's really hard to find any easy answers on. If it were Link or Haltech, someone would be able to just send you a ECU file though.
    • Yes sir am asking is there possible way from aem tuner from wiring pins 
    • Have you checked cam to crank timing and confirmed balancer marks are correct?
