It is a rather silly idea, in this man's opinion, to swap in another 4-cylinder engine, when the one that comes with the car is fully capable of doubling it's stock horsepower and destroying the tranny and diff., on stock internals.

I dont get why people say, "Ya I love 4cyc I dont like 8cyc!" What the hell? They are both motors, do you think somehow an 8cyc is worse than a 4? Its annoying when people dont like "American" and "V8" for almost no reason.
V8 roar > Vtec
When I see posts asking about crazy swaps and sky high HP, I would love to see it happening but 99% of the time its just somebody dreaming.

if you really want to dump the BP/B6 for another 4cyc there is an sr20 or a s2000 motor. Both swaps have been done before on a miata. They take a crap load of work but at least you can get some info for that on the net.

if you wanna stay with a 4 banger go with an sr20det which has been done a couple of times or something i havent seen done an f20 c from an s2000 if youre a honda fan .the s2k stock runs 13.8 gets great gas mileage and the s is about 400 pounds heavier then a miata

Ok thank's now I know that youd don't like the idea of puting the srt-4 engine in the miata. I've only asked about it because it isn't a very expensive engine. I've seen the sr20det swap before and it looks nice. Does anybody know how much heavier this is from stock?
EDIT:it is 2300lbs. sorry. didn't read carefully.

theres an s2k swaped one on m.net some where, the guys said it wasent any faster then his 1.6 on boost ,the only upside was that it doesent get hot like a turbo car during autocross, i would just keep the 1.8 you have, quick question have you ever riden in a 300+hp miata? if you do you might not still think you need 400hp, just my 2cents good luck on the build one way or the other

Yes, but isn't the KL-DE lower compression, working pretty well out-of-the-box with boost? Then again, if I had the time and money to do an engine swap, either engine I put in would get forged internals, so I guess that's a moot point

There's a guy on mx6.com (Fastest95PGT) that has a stock ZE that makes 317whp/287wtq @ 8.5psi. The car is megasquirted, but other than that, the engine is relatively unmolested. The setup i described above is capable of much more.
