I was just saying if i were to do a swap i'd swap in a motor that was NOT a 2JZ, Honda or LS motor.

Oh so you were agreeing with me lol. I'm sorry I totally didn't get it now I see what you are saying.

LOL, same.

Easy killer, I don't want to turn this into a ford vs chevy debate. I never said LS motors are blowing up left and right. LS motors are ALL great, particulary the LS7 and LS3 (in my opinion) its just not what I would choose for this application. I like the Boss motor even more, and would rather pay $11,000 for it than have an LS3. For this specific project. You are just going to have to live with that lol. Then again I would also MUCH rather haven LS9 than a Boss 302 engine in this car, and I would MUCH MUCH rather have a brand spanking new Corvette ZO6 than an FT86 with ANY motor lol. Hell I'd take a 500 hp Z06 over a 650 hp GT500

I know the LS3 rocks. I just like the Boss even more. OK?????

The Ford engine will have a much higher c.g., you know. Not likely to fit, anyway...

But anyway, the problem with the FR-S/BRZ platform is that even with a very short 2.0 flat-4, the weight distribution is 53/47 with two occupants and a full tank. It'll be 55/45 with a driver and half a tank. Just about any engine swap is going to move the c.g. forward a fair amount, not so good for putting down serious power...

Thats not a bad idea. It would be a better pontiac/saturn solstice/sky then gm made lol Not that they were terrible, I actually enjoyed the Sky Redline I drove, they were just horribly impractical, even with the top up.

With the reliability issue what I was really alluding to is durability under abuse, and not for drag racing I meant continuous lapping at the track. A stock LS3 or a stock 'base' Coyote 5.0 will theoretically break long before the stock Boss motor under racing conditions. Sure you could build an LS3 up to be as tough as the Boss motor and even more powerful if you wanted, and people do just that all the time, but the Boss motor is track ready as is, with a warranty.

Eh, the cog wouldn't move that far forward. It would certainly be higher than stock, but in this car it would still be very low regardless. I would do a full overhaul of the car if I were to commit to the project. Wider wheel base, wider body (fenders anyway), huge sticky rubber, low tight fully adjustable suspension, etc. I would make the car extremely light and stiffen the hell out of the already very stiff chassis (including full roll cage).

Would it be worth it? Doubtful. Awesome? I'd say definitely. Lol

would this fit?




lol

Depends on your fabrication skills I suppose

Reminds me of my favorite "modded" off-roader I bumped into. Riding ATVs in KY with some friends we were met coming the other way by a Suzuki Sumuri on a custom frame with tractor tires and a Cummins school bus diesel engine! Sadly I did not have a camera.

It was like meeting Sasquatch! The driver stopped and shared some "homebrewed alcohol" with us. I abstained.

What engine would you choose??

Has anyone been able to fit a H6 into one of the twins?

There is actually one japanese shop car with an H6 in it, but I think it was the older EZ30/6, not the newer EZ36R.

Out of curiosity I looked into this swap for a little while, and it seems like it might be just as much work as any other swap. Although some places quote that Japanese car as using the stock trans, saying it bolted up. I couldn't find enough info on the bolt patterns of either the FA20 or the EZ36R to say whether it is possible before my curiosity ran out though. The most I got out of it is that the newer EZ36R would be the best bet, although the older EG33 is pretty cheap and has been done a number of times into a bunch of different vehicles.

I believe @PERRIN has some experience with an EZ30 swap...

But I think the bottom line is that it would probably run somewhat more expensive than an LS swap.

EDIT: found the car from Japan

With the H6 swap you do keep the horiginal design for the car with a engine that has a very low center of gravity.

Looking at the Vorshlag LS swap, it doesn't look to sit all that much higher:




Don't get me wrong, I love the idea of an H6 in this car. I think it would be awesome. I just think it would be one of the more expensive options. As far as power goes, just about any stock LS engine will rip the H6 pound for pound. I think to make it worthwhile, the EZ36 will have to be built and blown, which is yet more investment.

Like I said, I love the idea, and if I had an unlimited budget I would absolutely consider it. But I would probably also consider a Porsche first.
