:bonk:

I don't know why this just didn't use that engine in the first place...
Yep, already been said.
You find a way to make that work....

S54
 

There's NO WAY it would fit and it would be way too heavy for this car, but I miss this motor...

BMW S54

I'm surprised no one said a couple of SR20s but they do pull a premium



































before Race Wars

True story...
Haha! Indeed!

No way it would fit, but the 1.6 liter supercharged MINI Would be great. (The 210 HP John Cooper Works version). Plenty of power, nice and easy to modulate power delivery, and nice sound effects.

4g63. because racecar.

I'll take the H6 from a 911 turbo. Don't know the engine designation.

i never knew motors like this existed. when the ls1 first came out and i rode in a friend's car, i thought cutting off 2 cylinders would make it a pretty sweet 6 cylinder for the base 4th gen camaro. probably 260-270hp in a v6 in the late 90's wouldve been sweet

Subaru flat6 EZ36D might be interesting. In fact, I like the idea of either of the turbo flat4 OR the NA flat6 engines from Subaru making into some later MY or special version like an STi. Coolest would be if they brought the big guns with a new OEM turbo flat6... One can dream.

I think though the easiest to do in the short term would be an EJ207 or EJ257. I especially like the idea of the EJ207. Those are pretty damn stout.

If money were not an issue any Formula 1 Engine would be the way to go. Crank that to 17K RPM and a magical symphony of teddy bears, unicorns and rainbows will bleed from your ears.

I was just thinking of an Sr20det, seems small enough to fit withouth issue, then again i could be far from right. I also thought of the 20v 4AGE that were swapped into the original 86s. Is is really hard to just throw in an STI motor in? I would think the swap would be almost drop in?

Yes! I totally forgot about the 4A-GE! I'm thinking it would be a fairly easy swap.

From my experience, STi motors are super finicky. I wouldn't be surprised if the swap was just a simple drop-in, but I also wouldn't be surprised if it turned into the swap from Hell.

Just gonna throw it out there: Cosworth YB.

2jz or ls1.

2JZ swaps have been said and done.

Will an LS1 even fit?

2jz is what i personally want =), and the ls1 will with a little elbow grease.

There ya go!

I like LS1 idea if it fits. That has been going into lots of cars as swaps and makes alot of easy, simple NA power.

Chevy small-block swaps have been done, and they are a little unimaginative. The more unique the engine swap, the better I think it is.

LS motors make a lot of N/A power because of their sheer size, but their power per liter is a tad unimpressive in my own opinion.

I agree, not very imaginative, lots of people doing it in lots of different cars now... But it's simple, easy, reliable power. I imagine this chassis with 350-400 NA hp and I think it would be pretty awesome.

True story...

Mugen MF408S -- 4.0l naturally aspirated V8 putting out 590 hp at 9,500 rpm and 383 ft/lbs of torque at 7,500 rpm. Oh, and the entire engine only weighs 289 lbs.

Here are a few more engines to add to the list.

1. Audi 4.2l V8 (32v) found in the Q7, A6, A8, S5, B7, and R8 -- 414hp at 7,800 rpm and 317 ft/lbs of torque at 5,500 rpm.
2. Audi 2.5l R5 (20v) found in the RS3 and TT RS -- 402hp at 5,400-6,500 rpm and 354 ft/lbs of torque at 1,600-5,300 rpm.
3. Suzuki 3.6l V6 (N36A) found in Nobuhiro 'Monster' Tajima's Suzuki XL7 "Pikes Peak" Special -- 1,007hp at 8,500 rpm and 752 ft/lbs of torque at 6,250 rpm.

Hmmm...how about this?

Cosworth YB, anyone?

Lee and the guys at Motus are cooking up some seriously badass stuff down there in Birmingham. They're good people. :clap:

I've been talking with Lee on and off for the past few months about KMV4 crate engine details, and, to tell you the truth, I cannot wait for it to be released as a crate engine. I have a 1974 Ford Mustang that is yearning for a new powerplant to replace the sad and lackluster 2.3l.

2UR-GSE in a GT86

That combination would be virtually unbeatable, and I do think Toyota should release a special edition version of the GT86 with the 2UR-GSE powerplant.

I honestly love this motor, and I think it would be a great swap candidate because it's on par with the Cosworth YB, they are a dime a dozen, and the tuning potential is near limitless! My favorite version of this engine was the 405hp variant found in the 2004 Mitsubishi Lancer Evolution VIII FQ400.

Yeah, because that would be street friendly...

I do like the idea of using an F1 motor though. Personally, I would detune the motor to around 500-600hp and have it redline at 8,000-9,000rpm.

For how much though? Im guessing that would be around the GTR price range. Well, as long as they slap in a SC with the version, i'll be happy to empty my pockets out.:D

If this car had this engine, i'd name the car "chop suey".:D

$55k. It'll have the performance to rival a lot of other super-cars on the market, and it should be super fun to drive.

$55k on top of the frs price huh? hmm...dang! i dont wanna lose my AC in the process.:(

No, $55k would be a reasonable MSRP if Toyota ever did produce a GT86 with the 2UR-GSE engine and manual transmission.

I dont think that it'll be the cheap. I mean how much is an IS-F? And considering that the gt86 is in demand toyota would bump-up the price, specially with a whole new powerplant. im pretty sure it'll be GTR pricetag and they'd release it as a lexus brand.

IS-F's are about $62k. So, you might be right: a GT86 with a 2UR-GSE might be priced to compete with the GT-R. I doubt Toyota will ever produce such a car, but we all can dream, right?

Yeah, all we can do is dream. Unless i find a trashed IS-F and buy the engine and slap that in my FRS, then do some tweeking and tadah!! im living the dream.:D
