Stroked KA

Post by **tl1000sga** » Mon Oct 27, 2003 1:53 am

Anyone know if this has ever been done or if there are any kits to raise the displacement?

The KA already has a long stroke to begin with... I personally wouldn't want to raise it further cause it would make you lose RPMs spent in boost. I would however look to increase the bore.

stroking the ka is not usually a very good idea..it's already overstroked(limiting revs). I don't know if anyone makes a kit, the best way to do it prolly is by boring.

Nissan already did it for you. It's called the QR25 lol.

Err, Why cant we EDIT our Post's anymore? Anyways, you could drop a bunch of cash and make a crank custom made for you.

Yeah I didn't think about the fact that it already had a good stroke, but you can't gain a lot of displacement by boring one. Or can you?

i am in the process of buiding my ka22de. fully counterweighted crankshaft as well. It will be like the medium fj that was never built. I really wish there was a nissan oem rod that was 170-175mm and used the l, z series journal width and diameter, i can only wish.

oh and i have a ka 2.5l in my car right now.

How did you accomplish the 2.5? Bored? How much?

Ya you can gain plenty...and the KA has a cast iron block so you don't have to worry about sleeving..

91.1mm bore, although the ka is a cast block, the bore are not siamesed and a few passages come very close to the walls. I would not suggest going over 91mm, and thats on a na application, if your wanting to go turbo dont even think of it. This engine is a test so i have been running it very very hard, also running 10.6:1 cr. It has passed with flying colors so if anyone wants a 10.5-10.6:1 high compression 2502cc build let me know. I cant wait till i have my 2.2 under the hood

is the 2.2 turbo or not?
