mx-3 v6 engine

[rerhard]

would it fit in a festiva? it's a k8 engine, i'm not sure if it's too different from the b series engines.

It has nothing to do with the B series engines, as it is a V6 engine and the B series are 4 cylinders. And no, it won't fit unless you're willing to do some major surgery to the whole car; heck, a BP barely fits, so as far as V6s go, you're better of putting it in the back.

A K series swap has been widely discussed, but to my knowledge, never done. It would require some serious surgery to be successful.

It is a tiny V6. Same displacement as the BP. 1.8. But nobody has done it. Bigger than would fit in the bay.

The K8 has the same footprint as the 2.5 that is in the probe or mx-6. If someone were to attempt the swap it would be best to use a KLZE, because it is ~200HP versus the K8s 120, and it is the same size.

Like he said, you can't just think an engine will fit just because of its displacement; the K8 is basically a de-bored and de-stroked version of a KL, that's why they have the same physical size and about every external part interchange between the two. Another example of your reasoning would be to think a Toyota 2ZZ-GE 1.8 from a Celica GTS would fit an Echo because it is just 0.3 liters bigger, but in reality it won't fit without major firewall surgery and maybe even a little frame trimming; that motor is huge for a 1.8!!!

I've thought about it. I went and measured a 2.5L out of a Probe and then measured the Festiva engine bay.
I think it will fit in the but it will be close.
KL Engine;
W - 25"
H - 25.5" bottom of oil pan to top of engine
H - 18" from center of crank to top of engine
L - oops forgot to get that one
Festiva engine bay - 25"
firewall to center of engine 14"
front brace to center of engine 11"
Even if you have to modify the firewall, so what. So did Matt, when he put the BP in his blue car.
You would have to use the transmission from the MX3 since the KL engines use a different bolt patten on the bell housing.
The MX3 front track is about a 1.5" wider than the Festiva so I'm not sure what to do about the drive shafts.
There may be enough play in them to allow them to be used in the Festiva. Or maybe use Aspire lower control arms on the Festiva. I think they are 3/4" longer.

Thanks for the clarification guys.

Suppose the engine physically fits in the engine bay, did you check out if the transmission placement would allow the right axle angles (IE if the engine is too far back or in front of the engine compartment for example)?
