it all depends on what your looking for in a motor i guess. for the s2k the F20c is a perfect match, for a vette the LS6/7 is a perfect match.

 

dude, i dont think anyone has been put a chevy LSx motor in a miata. definitely would be a great idea compared to a mustang 5.0 motor

Lsx = aluminum, good for roa and drag racing
5.0 = iron, aka big heavy POS, great for drag racing

regardless, i think its better to have a peaky motor in a road race application, of course with proper gearing and driving. too much torque can be annoying trying to pass someone through a turn.

 

considering the manufacturer of the s2k, yes the motor is a perfect match.

but, there is someone on our forums with an LSx swap in his s2k. not running yet, but he was able to get near stock weight distribution, plus it weighs less than a stock s2k considering his weight reduction.

Chevy motor ftw?? maybe, it might just be too powerful to really run hard at a track.

 

I think F20C would be the way I'd go. I think it'd be a good match for the car as it was originally designed. Nothing against V8s, but that's such an obvious been-there-done-that swap, I wouldn't do it just on that reason alone.

I think this is probably one of the ultimate track setups for this platform.

 

well you have to look at this:

the F20c is forged from the factory. it responds very well to boost. just look at IP'd cars. 3mm HG, EMS, 3in=400whp+, 500whp with few other supporting mods, for about the same cost as swapping the whole engine.

the reason its a popular swap for RX7's and other cars due to their less than idea stock motors. in the s2k application it really isnt justified, IMHO.

 

Bull pucky. I wouldnt want an LS1 in my S2000 as much as I would want a F20 in my Z06

 

My choice

 

We have an s2ker who has already done this:

First, it's the V8 engine + tranny that weighs 200 lbs more, not the engine alone. The V8 is smaller but not lighter than the Miata 4-banger. And since the weight of the short block is more to the rear than the front, and a new rear diff is installed, F/R weight distribution isn't thrown off that much actually.

I thought it had to be the Ford 302 because of tranny fitment issues (ie Ford bellhousing is compatible). Has anyone done an LS swap, cause I've never heard of that.

 

A bullshit statement! The LS engine has the power advantage due to MUCH larger size. One is a LARGE pushrod engine while the other is a small DOHC engine that revs to 9K - apples, oranges. Is a Harley's engine better than a sports bike's? Apples, oranges.

Personally, I like my 8,9K-revving engine just fine. To me, FC>LS.
