just need some quick answers since i can't seem to find it

1. Whats the physical size of the engine in the s2000. Height, Width, Length wise......or Volume. Size of Engine bay in S2000 i'm assuming should relate to this.

2. The physical size of a Chevy LS6 engine. Height, Width, Length....or volume.

 

Good luck. It's hard enough just to find weights let alone dimensions.

LS6 weight: 497 lbs

F20C weight: 326 lbs

 

well i did say i couldn't find the info...;-)

i just want to see comparatively how much volume does the F20C take up......

i know that people at the miata forums swap in Ford 5.0, LS1's, chevy 3.4 v6......because they are "compact" and i think a few said the F20C probably won't fit in there engine bay. That plus engine cost.

i mean...how much bigger can the F20C be volumetrically?

assuming the weight difference in the engines you found is because of Iron vs. Aluminum......the 150lbs weight difference don't reveal the true volume of both engines.

 

the f20c is actually pretty small. I think it's a little bigger than the D16 (yep, D16 SOHC).

I think the reason it may not fit in the miata is the transmission length.

When they say LS1s are "compact" they are still relatively large, yet "compact" for a ~6L engine. To fit the 302 in the old miata, you had to cut part of the frame.

Also, I believe that there are custom bell housings to adapt different engines to the Miata. No such thing exists for Miatas for the F20C.

also, why would anyone want the chevy 3.4? That thing is a turd. I guess it must be cheap.

 

Note that there is a 50 lb weight difference between the manual trans LS1 (~500lb) and the auto version of the motor (~450lb). Both weights are reported to be "dressed" but you never really know what all is included with that weight. I also don't know why their is a 50lb difference between the auto and manual.

As for the 3.4, as installed it's a lame motor. However, this little thing has lots of potential. As is, it's only a bit heavier than the Miata's 1.8 but it's got almost twice the displacement yet it's smaller in dimension. Sure it's not lots of hp/L but it's a lot more liters in the same space. From what I've read it's easy to get ~240 Hp and good torque out of that little motor. Also, for those with money to burn, GM makes an alloy race block for that motor. You then have a 3.4L V6 that's smaller than the stock 1.8L I4 and weighs less yet produces over 100 more hp. Chances are the gas mileage does suffer.

actually the 3.4 v6 should get around 30 mpg.........it's better then the miata's 1.8 in fuel economy.

it also uses regular fuel unlike the miata's need for premium.
