So after grenading the b20 me and my buddy got to chatting. We can get a j30 for 150 from our local upick. Was searching for a b but they are getting rare around here unless you buy full cars. I noticed that the J engine sits on the same side as the k engine. Also k24 flywheel fits a j engine. We also know for a k20a3 gearbox and shifter linkage for 300. Does anyone know if the spline is the same between k24 flywheels and a k20 input shaft? Also will the clutch and pressure plate from the a3 5 speed gearbox fit the k24 flywheel? We are thinking about the possibility of making an adapter plate here so we can mate the 2. I know the tl type s 6 speed is what a lot of people want, and I also know that I should search after a j32a. But I'm cheap and am thinking this could actually be done. Or are we just smoking too much weed?

J trans do break as easy as the k-series when torques applied.

Ooooops I meant do not break as easy, damn typing and proof reading 

In other words J-trans> K-trans. for strength

Was reading up about making a "J2K" adapter plate a while back.  The issue from what I was reading (again, I never got to put my hands on a car with each motor at the same time) seemed to be on the J-series, the starter hangs over the trans, nice and out of the way, while on the K-series the starter faces the other way (towards the engine).  Not a problem with a 4 cylinder, but it likely would be with a V6.

It would have to be more than an adapter plate.  You'd have to hack up the bellhousing a bit to put a different starter on there.

My guess is he wants CHEAP first, power holding second.

A j-series manual box is not cheap.

No it is not, my brother paid 1k for his and that was considered cheap....

In the grand scheme of transmissions 1K is cheap for a transmission... Just saying.

Exactly a grand is hardly expensive for a low mileage clean transmission. These dont come from throw away cars. It's also not the most common one in the world either.


When we are looking at lets say a b series hydro transmission it's a 15+ year old unit that most likely needs to be cracked open for bearing replacements/seals etc. When done right there is no way to do this stuff on the crackhead budget unless you just throw in stuff and hope for the best.


I like the j series stuff the transmission from what i gather does not have a recall on the 6spd unlike most of the small geared k series stuff. If the transmission handles a 3500 pound car throwing it in a 2000 pound civic with a driver that doesnt miss gears left and right thing should be pretty bulletproof.

If you have a means to get in on auto auctions such as Klodies, you can pick a good six sp cheap.

I local Hondaphile (Chad) picked up an Accord V-6 w/ 6sp with 40k on the meter for like $2k.

Turn around sold parts of interior, engine, exhaust, front brakes ended up spending nothing on the 6spd, just time.

Most people also dont have the luxury of parting out cars in their front yard either

Fastest j swap is a auto civic on a stock motor! Line pressure anyone.

IIRC Fred's freeEMS is powering an accord with an auto-J with a big ass turbo. In the end the heft of the larger motor wont' win any handling contests so you won't need the gears for corners, and the torque can actually benefit you when not changing gears as much.

Having a strong/fast auto Civic/Teg for a DD would actually be nice.

The idea here is what I have available to me on a low budget. I know a machinist he makes up adapter plates for a few v8's and jeeps. I figured he can tackle something like this. Second of all I can get the k trans and j engine for just over 500. I like to do shit cheap for fabrication experience plus the fact that I did it. Will it hold together? Probably not... Will there be a J swap in my car for under a grand... Quite possibly.

Like I said above, what are you going to do about starter?

Is that a true tt setup or a compound setup?

The thing with melt vs crack is this: If you have minor detonation (pre-ignition is a different thing, btw) the shock waves knock the skin of cool gas off of the piston (and chamber) and remove a layer of insulation thus over a few cycles allowing it to get really hot and then melt. If it's not so minor you just break things outright with no chance of such overheating before other major damage is done.

Wow, never knew that. Disruption of the boundary layer to cause melting is something I never would have imagined. I might start reading all your posts over there to find more of your uncontrollable knowlagabilities.
