I'd be interested if it was for the DE. Althought I might go the crazier route and swap an SOHC into an S14. I like to be different.

My car is in the restoration phase right now but it would definately be great to know I could get this stuff when I'm ready for it.

I am in the process of researching (search and subscribe :)) and have found some parts that I like.

Package deals are good and competition for these packages are great.

I have a DOHC and wouldn't mind seeing what you have to sell.

How about some low compression short blocks for turbo applications, on the KA24DE. I think there would be more of a market for turbo shorts blocks on the KA than for high compression NA setups for the E. Could be wrong though.

Oops I forgot to mention. I want a low compression block for turbo apps.

KA20? How much destroking are we talking about here? That would be quite a bit I think. Do the math and get back to me...I was thinking by destroking to ~90mm from 96 that you would still have a KA22 or KA23 depending on the bore.

You actually know a place to get the KA20 cranks?

And don't you think that an 89.5mm bore would be preferable to allow for re-using the block?

I don't know what you are speaking about but this is one of the most interesting threads I am a part of.

Destroking for higher rpms?

Yes, but it's been discussed in detail at FreshAlloy over a year ago. They were thinking that it might be possible to use L and Z series motors' cranks in the KA, but found it wasn't.

There was a KA20DE however that never made it to America. Using that crank would definitely allow for some very cool possibilities and let the KA rev much higher I would think.

Of course, with a custom billet balanced crank, titanium rods, and different cams, I think with stock stroke and maybe slightly longer rod length, the KA would rev to 8,000. That's just an assumption though.

"The KA engine is different than the L Series. Both rod and Mains are different than the L-Series. None of the L-Series cranks will fit either of the KA blocks (truck or 240SX).

Not only are the rod shells narrower but the locking tab is on the opposite side from the L-Series rod. The rear crank register of the KA motor is different than the L-Series. All of the work done here on the KA engines was done with the OE crank. I do not know of any other crank that will fit in the KA blocks. "

But good luck anyways...you might find something they missed.

Why would you want to lower it?

It's already at what...9.0:1 or along those lines? That, to me, is great for a turbo motor. Many people go with 8.5:1, but tuning is more important.....no reason you can't keep the 9:1.

deviousKA wrote:yes that negates the ability of using ka rods, the information in that thread does not give me any reason not to continue my process. we will see how it goes.

if it is totally impossible, there is still possibility of using a l/z block, which could be stronger anyway.


I hope you do find something! Good Luck and keep us posted.

hey, i remember that email!;)

i'm not trying to discourage you deviousKA, but what you are trying to accomplish is going to require A LOT of work. i and several other ka24e enthusiasts (not just the people in that one FA thread) have exhausted the idea of building a destroked hybrid ka24e. it's not impossible, but it's just way too much work. you're pretty much building an engine from scratch. everything you try to use will need to be modified or custom made.

as exciting as it may seem to be able to offer a killer all motor detroked ka24e, you'll find that when you do pull it off, it'll be way too expensive to attract most buyers.

good luck.

well, did a quick search on the good ole google. KA20DE is a standard motor in the J-spec and NZ/AUS spec frontier and the new nissan caravan model. I bet you'll be able to pick them up for peanuts.

I am having a guy send me a 91 DOHC headgasket. we'll see if it lines up to my 89 SOHC head gasket. If it does, its open season. next stop is a Z20E shortblock and some custom lenght timing chain, and a set of 88mm bore 300zx pistons.
