I've heard u cant get 1045 kits anymore

Well the original question was as quoted above... And Wiseco would have probably removed them from their website if not available, although I could be wrong...

Either way,Big Joe wants to know what size the sleeves/block could/would be in mm's and would still allow him to Bore to 1075cc's.

The answer would be 1045cc's 2.795/71.00mm's

thanks..the guy said its less than 71 and more than 70. painted black, but i dont fking care.

KZZONE's current listing doesn't show a 1045cc line item for Wiseco or otherwise.
Am thinking 71MM bore is 1045cc.

If a well-worn "1045" is being considered for boring to 72MM, am thinking it wouldn't hurt to measure with bore gauge to assure enough meat remaining in each liner. It's getting pretty thin at 72MM, especially where FSM says max is 71MM.

Would defer to Kraz1's opinion about this.

Good Fortune!

I've run 30psi of boost on a 1015 block bored to 1075 with 9to1 pistons, that's a dynamic compression ratio exceeding 17to1. NO problem!

Isn't this a typical stock 1015cc KZ1000 block that started life at 70mm and which has since worn to something less than 71mm?

KHI provided two piston over-sizes for KZ1000, the first being 0.5mm and the next being 1.0mm.

Presupposing normal wear, the less than 71mm should allow boring to 72mm for 1075cc.

Good Fortune!

Joe when you get that busa can I have your kz

whats a busa? never heard of it.:dry:

Joe, depending on labor for the installation vs. the price of a used block you are going to have bored anyways, it might be cheaper to have someone install sleeves into your current block.

Nevermind, looks like the sleeves APE sells are all big block sleeves.

well theres your answer joe!
do a stock rebuild with welded crank and replace anything worn.throw a set of 8:1 1015s in there with a stock head with good valve springs and stock cams with a turbo!
you can tune it to run just like a stock motor in hot weather or crank a few lbs of boost into it and have an instant 1075 killer on pump gas
