How To Build A Tuff 20

[RB power]

hi all

just wondering what is needed internally to build a rb20det to produce over 300rwkws?

are there any little tricks of the trade to building a solid rb?

what oil and water pump should i run?

what brand pistons,rods,bearings,bots are recommended?

whats the max lift cams i can run with the standard valve springs?

i have the turbo, injectors,exh mani, gate, pump and pump already.

cher cher

Please read the Forced Induction Guide.

Is has a link to a thread about 260rwkw+ for the RB20.

Its over 6-7 pages in length so its possible some of the information is in that thread.

Personally, i think you are wasting your money

don't be so harsh on the RB20 Ash, you know it's got the minerals to keep other engines honest ;-)

lol Goran! Reply to the FA mail you donkey

You know the RB20/300rwkw is well above a 5000rpm adventure.

Not my cup of tea

Probably...but if you have pistons, clean up the top end with some baby cams and some tweaking of inlet/outlet and chamber...nothing dramatic as ti not lose bottom end. The make sure you havbe oil pressure and temp well under control...then 1.5bar up a GT30R will net you close to 300rwkwsand still be pretty driveable

A GT30 you'll be running ~25psi for 300rwkw

Thats a LOT of boost for not a large amount of power and even running a ball bearing its gonna be very harsh

Remember i ran 270 @ 17psi....

eh not quite man, i pulled 288rwkw on 17psi...and this was on a motor with poor compression.

its possible to do but there may be cheaper ways to go about this.

if you are interested in 'beasting' up the old rb20 take a look at my rebuild thread...ive done everything but rods in the motor.

Are you in Aus Carl?

[carl h]

nope, im a damn yankee apparently here in the states.

let me tell you how much fun it is trying to source rebuild bits that you guys can walk into any auto parts store and get...

Thought as muhc, youre 280rwkw probably is around our 240rwkw from what we have seen

[carl h]

boooo.

i dont believe in dynojets like most guys round here, either dyno dynamics or mustang...its bout right .

hey mate

if you wanna know how to build a tough rb20 pm dan ( 3lit3_32 )

his rb20 was good for almost 270rwkw (if not more) with a stock head.

he has almost finished mine which is almost identical to his but with head work done.

he would be more than happy to point you in the right direction
