a) TY, do you have any of your dyno charts scanned on the Internet?

b) How much do FMAX kits usually retail for? (stage I or II)

c) What are the major difference between the 1993 and 1995-1998 KA24DE?

I'll answer the third question. 91-94 motors have an external coil, different emissions controls, and the 240/248 degree cams. They also have the secondary butterflies in the intake. 95-98, internal coil, 232/232 degree cams. The MAF is a little larger, the catalytic converter is mounted directly off the manifold. Aside from the emissions changes through out each year, everything else remains unchanged from these setups.

I'm going to have to argue the secondary butterflies in the intake on 91-94 Ka's. This is not true. I have a 1993 and this past summer I had the intake manifold off for a little over two months polishing. No butterflies what so ever in there.

How do you get around this (or do you have to) when placing a '95 motor into an S13? I know most everything else (MAF, other sensors) can just be swapped, but what about the distibutor?

Thanks - Brian

Swap it, that is what I did.

All you have to do to swap an S14 motor in an S13 is swap the intake manifold and distributor off the S13 motor onto it and drop it in.

Are there any major differences in the head design between S13 and S14 KAs? ergo, would it be a bad idea to buy a used '91 head, have it ported w/ 5 angle valve job, etc?
If this is a plausible idea I may well hit a junkyard and do it.. Please let me know.

Most do. Maybe not all.

Everything I have ever heard/seen shows that all S13's have the secondary butterflies. Have you owned your 93 since it was new? If not, then you don't now for sure if someone else removed it.

I'm not too sure, but from the looks of things, I really doubt someone removed it..the thing was totally stock when I bought it a year ago..hell even had the stock head unit..lols

I'll have to back Blitzkrieg on this one. I have a 93 as well and it has no butterfly's in the intake manny. Could be something Nissan found to not be needed during the 92-93 model change.

Is there a large vacuum actuator on the back of the manifold? I've seen a 93 that didn't have them either, because it had a 95 upper plenum on it. The guy who had it before had done it for some reason. Still, I've seen them on at least 13 91-94 cars, so maybe it's only a coastal thing, or something. I can't see why it would be an optional item, it takes a lot of extra time to put it on.

Late '93 KA's butterfly valve was removed... Nothing to be alarmed. '94 KAs also are missing the SCV.

Yes, several of them, but I don't have a good link to them right now. You'd have to search for them in older posts.

Here's one of T.Y.'s dyno charts from a while back...I believe at 11 psi?

Yeah, I didn't look at the picture carefully until after I posted it, and I was too lazy to go back and edit the post. I'm impressed that I remembered the right number!

Here's the one at 15psi with 91 octane pump gas.
