Rb20 Strenghtning Bottom End

[rb20powersilvia]

help!! CONFUSED

My cars in the smash repaire's getting work done and a paint job. Im thinking now is a good time to take out the engine and give it a good freshen up bottom end and maybe head.

Ive read the engine is capable of making 400hp. im aiming at 280kw atw well around that figure and i wanna know what should i do to the bottom end without putting a big hole in the wallet.

My mechanic told me nitrate the crank and something else to do with it.

Also new bearings and rings. But if the bores have score marks, will have to bore it out and get oversized pistons.

Can anyone recommend or give me any advice on what i should do to the bottom end without going to crazy as ive read even the standard bottom end with more then 100,000km's travell'd can get a little more than 300kw's atw.

Is there a midway between standard pistons and forgies?

Will the rods be ok ive heard something about prepping?

Will the rb20 gearbox hold up with the occassional squirt of this power.

Cheers.

The standard bottom end is good enough as long as it's healthy.

Read some of the RB20 posts. These engines take a nice beating with little problems if it's thrashed the right way. As far as your gearbox, it may need some work.

my rb20 was making 288rwkw's for a good bit there before it mysteriously melted a hole in the ringlands. <_<

if anything rebuild it with some forgies and good management, old girl will hold the power properly tuned.

bottom ends go bang when drifting

Out of interest, what goes bang? Pistons, bearings. A bit more info would help, like the the power they were makign and whether the oiling, cooling etc were std
