Aiden, the motors yours. I can probably get it out to you at Oran Park at that NSWRRC supersprint if you're still going to it. Give me a call on 02-9631-2043 & we'll arrange when to pick it up.

LZ or an OS giken 1.6

What about using a ga16 from a pulsar. not sure if there is a rwd box for it though

i was thinking maybe Z18 block as they are the same height as L20b arent they?

and probably also have the bigger main journal size that the L20b has meaning that the z24 crank would go in easier

I honestly cant see the z24 crank in an l18 block with 207.85mm deck height
it would mean itll need l24 rods at 133mm, 27mm piston comp height and
rod stroke ratio will be 1.375 impossible.

I do believe an L20b goes in with 31.75mm pistons giving 1.547 but needs the
skirt to be modified to miss the counterweights.

Full sleeving/grouting an L18 to 91mm will give 2237cc

Must be using the L20b block which is 20mm taller.

ive got 2 CA18de's, neither of them have oil squirters and both have crank girdles
apparently its only the early CAs that dont have the girdles


where would you find rods short enough to fit in an L18 with Z24 crank? the pistons in my L18 nearly hit the crank and its only an L20b crank

what an awesome way to extend the life of an old L series into the new millenium!

Love to put one in an 1200 coupe.

Aiden, I'll talk to my friend, see if he has any plans for this motor, will PM you with the answer. I bet Chris P would know an old diesel mechanic that can explain the liners for you. I found the SR20 liners on an American website when I was looking for KA24DE pistons, but can't remember the website.
D , the guy with the L18 can be contacted at Waterhouse Auto Care on 02-4721-7227, ask for Jamie. I tried to pick his brains, but he needed to build a motor for the next weekends rally, so I wasn't going to interrupt him for too long. He uses the 120Y in state rallies & khanacrosses, & as I was selling him a Z24 crank, I think he'd be willing to do this conversion for other people.He did mention that crow cams had some blank camshafts, but he just used the standard cams in his motor.

Aiden glad to see the dream is still alive now thanks to Paul :)

Found another thread somewhere saying the ca18de blocks also have
the oil squirter just not setup. Dont know what that means but there
are parts galore at the moment.

Interesting to hear about the l18 twin cam ka hybrid I didnt know anyone
finished the twin cam conversion for this head let alone on a shorter
l18 block which would be an awesome way of getting around the rules for
racing and the street, no pollution gear.

Hi Paul, yeah i'd be interested in the CA, doesn't matter if its in bad nick, I would be rebuilding it anyway. I'd be happy to sling you some cash for it as well if you want. What's the deal with the liners to make it two litres? I'm guessing they'd be well into the water jackets?
