Peak Power On Standard Internals

[nemo]

Just wanting to know the limits of a rb26 before u should put forged internals in it, or what power has people got in their rb26 with standard internals, mine has 315kwatw.

Stock R33 bottom end before I rebuilt it (not due to failure of bottom end, just crank keyway) managed 352RWKW for ages no probs and reved her up to 8500rpm. Serviced it every 5000k and then 3000k's though, oil and filter.

600HP at the crank is a well known limit for a stock bottom end.

Rods are good for 400rwkw plus.

Pistons are pretty good, but will only take so much detonation/poor tuning before they fail.

Crank will take a lot, cars running up to 1000hp.

Oil pump and drive is a big problem with 32 cranks especially.

Blocks are good for a lot, unless bored out excessively, 1991,1992 had issues with cracking. N1 block (24U) is the serious block for big power...

Thats a quick rundown, other guys will add what I have missed. There is also a s%#t load of info when you do a search too.

Cheers.

How far are people confident of pushing the standard rod bolts?

I watched a dvd from japan with an 800hp rb26 drift car w t88 on stock bottom end. Lasted for quite a few hard laps and didnt blow on the show.

na i didnt even think about it, sorry guy and gals.

so with what i have read and researched 315kwatw is a safe power output for my `93` 32gtr?

the next stage of my car mods will be a engine rebuild but not for another 6-8 months (to raise funds), ive had garrett gt2860r turbos put on about 3 months ago and with them running at 40% ( about 10lb boost) the car still made 315kwatw, when they tuned it i told them i wanted it at a very safe level for standard internals but really when it comes down to it i have know idea whats on the inside, for all i know it could be chocka block full of jun parts.

and if anyone wants to know martin donnan tunes my car

cheers

Usage makes a huge difference my 32gtr let go on the track making 427 hp at the wheels on a stock bottom end

I suspect would still be kicking hard of it wasn't used on the track. No oil mods just a catch can and baffled rocker covers!

next on will have all the oil control mods under the sun. there is a huge thread on oil control mods for drift track on here just search

sydneykid started the thread I think.

we ran cats race car (r32 gtr engine with 100,000+ kms) at 340rwkw for 2 seasons in da before she killed it doing donuts

[nemo]

whats a good $$$ figure for a engine rebuild with all forged bottom end and rebuild head?

[GTRsean]

10k plussssssssssssssssss

Dirtgarage would be one of the guys to ask......

[R31Nismoid]

bottom end plus a top end touch up (not a top end rebuild)

7-9k depending.

Top end upgrades come to probably near the same

[Bumblebee]

ive spent around 20k... lol

I remember seeing her in da dvd serious performance 7; seemed so innocent but she will blow your bottom end.

Not bad mate; pretty much a whole car worth.

[Bumblebee]
