an fe3? that would be a pretty nice swap.

As for 6 cylinder motors, it seems like there was someone on the miata.net forums who was working on a 3.4L 6 swap from ... um a rover or something? Idk though ... something about a high revving 4 banger is what makes the miata what it is. It wouldnt feel right with torque at 1k

if only there was a miata trans capable of handling all the power this imaginary motor was able to produce under boost without the use of adapter plates.

it would be too good to be true

I still think a Maz KL with twin turbos would be sweet after seeing the KL swap photos. There's a guy with an mx3 running a single turbo KL making near 400whp... tho trannies don't last long.

Flipside just shoved a CA18 DET in an AE86. They have a conversion kit available as well.

The Vr6 is absolutely one of the hottest sounding engines ever built. They sound even better with 18 psi shoved down their throat.

I bet!

So being that you're probably best to answer this question WOT, is there anything you can foresee as a huge headache for someone trying to accomplish this swap?

The new generation of Honda motors spin the right way.
I'd like to see an SR20VE swap. An alloy NA 4cylinder making 230whp would be very nice in a Miata.

Are the VR motors iron? Can't seem to recall. I'd like to see a built NA VR6... something about an equal length header with 6 runners is very appealing.

VR6 would certainly be original. I like the idea of waiting for them to mazda speed the new Miata motor with a DISI head and getting that bad mother swapped in.

I <3 the new Disi system...so much good engineering, and no need to swap to larger injectors. (not to mention i don't think there could possibly be injectors with more PSI).

Low end torque would be pretty bomb, for well drifting anyway...torque that doesn't stop would be great.

On a side note though, my plans for my own block is not to bring torque down lower (though I do plan for quick spooling turbo. so i do to a degree) but rather when all is said and done I plan to boost and rev to 8700. Not incredi-high but still safe IMO. Along the way I will def. need a coolant re-route else as RPM find themselves over 7000 things might get melty.

As in a 3 rotor?

I'd agree if it weren't for the size weight and cost.

Actually it isn't that big of a deal if you keep them NA.

20B = big, heavy, long, unreliable, expensive, inefficient. Next?

engine codes are meaningless to me... what car is that from? S2000? I know the S2000 swap has been done before with positive results.

RSX motor. Not F22 (s2000) unfortuantly. Both spin the right way though... doubtful its worth the time fabricating though.

Do the Honda motors come with the big *** body kit and the annoying APC wing?

No, they come with underglow, short shifters, cold air and catbacks. The wing and body kit is something you get added on in your apartment parking space.
