The FRS is swapping badges but what engine would you swap into it?

How about two Kawasaki 1,200cc four cylinder motorcycle engines mated into a V8 via a flat plane crank?

I’ll take TWO.

The Evora V6

I have a secret fantasy of dropping one of these into a BRZ.

boring and obvious - but the already turbo’d 2.0 flat 4 out of the WRX - still don’t really understand why that never happened...

Isn’t that kind of just the Camry v6? That sounds weirdly possible.

you even need to swap the motor. just bolt on the turbo bits to that block. they both use the FA 20

Yeah that’s weird. I imagine it’s some kind of contractual thing and Toyota and Subaru are each waiting for each other to make the first move.

Basically, but with a supercharger

You mean like... towing it on a trailer behind the BRZ? lol. I don’t think there’s a universe where that fits.

Nick Has an Exocet > Supreme Chancellor and Glorious Leader SaveTheIntegras 02/04/2016 at 00:20

Yeah, it sounds plausible. Like... could be done from the factory.

There is only one engine wish to place in that car. At some point I will put a voodoo V-8 in one of those things. I really hope they release crate motors of them otherwise I must wait for the demise of a 350 and that would make me sad.

I was just having these thoughts this evening...

the EZ30D/EZ36D Boxer 6s are only 20lbs/18lbs heavier than the stock FA20D (so I’ve been told). I’d probably start with a later model EZ30D as a straight swap, then build it up and turbo it when I got bored.

I mean, listen to it...

Ford Econoost 3 cylinder for gas consumption of course.

Who am I kidding, two Ford Ecoboost 3 cylinders mated together for ultimate 90s Japanese inline 6 and twin turbo perfection.

Actually its a bit harder than that. The WRX turbo setup would drag along the ground as the engine is mounted much lower in the BRZ. Also you would need to switch to a front mount inter-cooler as the BRZ lacks the hood scoop, and the hoods that have them either are not fully functional or dont lead to where the top mount inter-cooler sits.

meh, raise the BRZ up. there goes your ground clearance issue.

and run no hood. there goes your top mount fitting issue :D

Yeah, I just spent a while googling the dimensions of the s85 and came up with nothing.

So basing off an s65 it should come out to about 917mm in length (probably shorter since that’s the entire engine length being counted as only 4 cylinders). There are people who have swapped 2jz engines which are about 787mm. It would be about 130mm longer. I imagine it might work?

Cooling would probably suck though.

I’d prefer to keep it at its current height, but after owning one for over 3 years now I’m ready for it to have a bit more power, luckily the after market has this car covered. If I to go really crazy with it I would go with the twin-charged build a company did in Australia.

think the sarcasm might have gone over you a bit...thought it would kick in when i mentioned the no hood part....

I know LS is the right answer, but ecoboost even though it’s fucking expensive as hell.

Drop something, anything in it. I owned one for 3 years and sold it when my brother in law beat me in a drag race with his Jeep. It’s not fast/fun enough to justify sitting so low to the ground with zero visibility. I had more almost accident close calls with that car than any I’ve owned. I couldn’t tell you how many times Jane Doe merged over on top of me in her Escalade because she couldn’t see me beside her. The days of low and slow sports cars are behind us folks.

I’d put a BRZ engine in it.

It’s not that simple, I think the compression ratio is different but also the turbo is too low from the fa20dit to be installed in the twins so would end up being destroyed

refer to my other comment to the other guy. just jack the car up lol

Subaru EZ30 3.0-liter flat 6. Just listen to it

!!! UNKNOWN CONTENT TYPE !!!

Don’t know why they had to put those silly badges on the intake manifold but whatever

The car isn’t set up for a tall high-CG engine or the implications of that on the front pedestrian crash standards that mandate so many inches of space under the crushable hood.

It is a subaru chassis.

FA20DIT is the natural choice. 275-296hp tune. (Toyota would re-designate the engine 4U-GTSE. (current FA20 is 4U-GSE, without the T)

The other engine, which I wish would apply... but all the less likely now that even PORSCHE is dialing over from flat-6 engines to turbocharged flat-4s in the 718...

EZ34R. (Toyota might call this 5U-GSE, or perhaps 6U-) It doesn’t yet exist, but here is how to build one...

Take the EZ36D short-block from the 3.6 Liter Subaru. De-stroke the crankshaft and con-rods to 86mm, same as the FA20/4U-GSE and leave the bore the same at 92mm. this yields 3430.2 ccs, 3.43 Liters.

Take the old EZ30R cylinder heads and replace the AVLS valve lift system with toyota’s Valvematic valve lift management system, in concert with the dual AVCS cam-timing management system (likely very similar between Subaru and Toyota engines anyway.), and add direct injector ports for D4-S compounded direct and port fuel injection, with a suitably performance oriented compression ratio.

Tune the cam profiles for a bit of performance, make sure the clutch, gearbox, and rear diff are up to the task, (R180 or R200 TORSEN rear diff, perhaps, with individual rear brake torque vectoring management...)

The EZ short block is roughly 2 inches longer than the FA/FB flat-4 block, due to the EZ having a shorter cylinder pitch dimension (cylinder center to adjacent cylinder center). Hardly a hurdle to overcome. Moving the battery to the back of the car would probably offset some of the relatively minor weight bias change. If it gets anywhere NEAR 100hp/L, which the M97-family Porsche 3.4L base engines could do also, we are talking 340 horsepower... Focus RS territory, when WRX STI isn’t even that high. The WRX STI could use the same engine... or even turbocharge that 3.4 flat-6 for even more power.

All of the sudden, an FT86 car with a 2.oT flat-4 or a 3.4 flat-6 upgrade, with somewhere between 275-345 horsepower, and LOADS more torque, and still ~3000lbs or a hair under... would go from an after-thought to the head of the class of affordable performance coupes. Power-to-weight would exceed the V6 and Turbo-I4 Mustangs and Camaros, and maybe ALL of the Dodge Challengers short of SRT/Hellcat... and could potentially edge out the 3200-ish lb. 350-hp Nissan 370Z for less money.

If Camaro and Mustang can offer 3 engine options, why can’t Toyota offer 4U-GSE, 4U-GTSE, and 6U-GSE engines?

Build it.

And for the love of anything interesting... build it as a folding top car.

With an 86mm stroke length, even the 3.4L version of the car can have the number still apply in the name.

GTS-86. S for Spyder.
