Dont rev it over 7500 and don't hit the rev limiter, it'll live.

I'd put a crank collar on it though personally.

think about it u got the motor apart any way so you mine as well, like this guy at work rebuilt some kia sh*t box and re used some of the piston rings??? lol stupid aye, but yer do the crank since it is apart.

i left my crank... hks pistons, eagle rods, balanced bottom end... 9k isnt a problem for it.. but i replaced my balancer for an ATI one..

builder said my bottom will live beyond 9k without raising a sweat... its in the balance i reckon

ah i spose if it can handle it no need to spend the xtra money i guess, how much kw u thinkn of making?

[Bumblebee]

me?? about 500awkw

hoping.. it will more than likely be more like 450-470awkw... depends how much i can get outta the hks gt-rs'

Im looking at 500-600hp on my stock crank. Just linished and fitted with a JUN crank collar. Save your money

just out of curiousity is anyone running the n1 pump without the collar? I didn't like the looks of the collars as you have to carve down the standard crank so it fits on then drill holes in the crank, which didn't sound like it'd do many favours to the crank strength >< the n1 pumps fit onto the standard 32 crank, just not fully on (like about 2/3rds of the way on)

thanks for all the replies guys ive just bought a 33 crank, will the standard 32 oil pump fit? i thought it did but ive heard from others that it wont. the oil pump was replaced 10000kms ago

Stongly suggest not to do that, the inner gear will crack over time, not enough engagement on the crank. There are pics on what happens to the oil pump gear.

Can't see why a stock r32 pump wouldn't fit on. Wouldn't it drive all of the pump with an r33 crank?

oh really? i've seen them crack under stress and that sort with the collar kits as well :S Will have to make a decision eventually, builds being done atm (very slowly), but at least the n1 pumps will take more flack before letting go than the standard ones will, either way i spose

sum1 told me that the standard oil pump sits on about as much as the n1 would anyway? can sum1 confirm

I'm sure the stock pumps do too, they only engage like 5mm or so of the crank.

ahh ok, thanks for that
