Has any FRS/BRZ fallen to LS V8 engine swap?

Times they have changed my friends

I have thought about an LS swap myself.....just because I can with the Hydra EMS. The problem is that even a front mounted turbo kit, front mount intercooler, and larger radiator hurt the car's balance in race form. It has more to do with the fact there isn't enough weight in the rear but I think for most street guys or track day people it's not going to bother them much.

Any chance that a rear transaxle could be adapted to mate with an LS motor? Even if it meant refabricating the tunnel at the expense of the back seat and or trunk utility?

[Element Tuning]

I don't think the width transaxle would fit between the OEM saddle tanks so you would have to add a fuel cell.

I'd like to know more about using the can bus method. Every one over here is saying its years away.

Well Hydra EMS specializes in plug and play engine management and not universal units. Since most current cars have CAN computers with increasing reliance it only made sense to develop the Hydra to utilize the CAN systems so you don't lose the coolant gauge, tachometer, speedometer, stability control, abs, air conditioning, and the power steering. We've actually been devoping it for a few years since the Subaru platform has used CAN with increasing functionality over the years.

So the Hydra has a CAN chip that is capable of communication with the OEM Can system. Each manufacturer has unique CAN systems so you have to have the equipment and more importantly an engineer to reverse engineer it. Once you find all the adresses, the data, and how the oem uses it, you can then get your computer to keep it happy or to make improvements and changes. We've actually made a number of improvements that prevent the stability control while racing from tuning back on even after its been disabled.

As far as I know the Hydra EMS is the only plug and play replacement ECU that is OEM CAN compatible along with being fully direct and port injection capable. CAN systems are much too advanced to not utlize them in your stand-alone engine management.

I think some testing has been done and the m1 is running with di not sure it's released to the public thou

I 99% of the time hate American cars, engines, parts, etc. but when they've done something right, they've done something right. and that goes for the LS engine. the cons are paled in comparison to the pros vs FA20.

I dont understand the "borrowed" part...

Not going to lie an LS swap is something I've been contemplating. Just need the cash to do it so it'll be a while. Here's to hoping the kits become more affordable...

[Element Tuning]

It will never be affortable, it will be for the guys that have the $$$ and feel its worth it to be different. Now If you happen to have a Z06 motor laying around it wouldn't be too expensive then Ha ha

Now building an FA20, fitting a turbo kit, and building up the fuel system isn't cheap either and this is where it might not be much more to do the motor swap vs. a build/turbo.

[bakerr6]

I think it all depends on the amount of fabrication you can do yourself.

There is a company in Atlanta, Electron Speed, who did the Motec for the Stout Racing FRS which controls both DI and PI, but that's not really plug and play.

interesting, there is another car with a TRD supercharger running it too.

Motec are actually developing a plug and play system ( on their site) for the 86's Motec.. YUMMM

[Element Tuning]

...and have you looked at how much Motec wants for their other M1 plug and play CAN bus application, without direct injection and simultaneously port injection? Only $7500 eek!!!!! I would stick to the Motec exhaust

FRS and BRZ owners complain about spending $1200 on tuning their car.

I'm just going to go header and catback with an E85 tune, lightweight flywheel and pulleys and lightweight brakes (uprated, natch) and light wheels for more performance. More honing what's already there than replacing or repurposing.

However, horses for courses. There will absolutely, definitely be a difference in angular moment and CoG if you change to a V8 but if you're going to do it, an LS is about the best choice you could make. Just keep the plastic inlet manifold to save weight and go with tubular headers for the same reason. Consider eliminating A/C, too, and relocate the battery, and you save a lot of the weight difference.

Another option is a supercharger, lots of people making 300whp with just a supercharger, headers and a tune and at a the end of the day that comes out about the same price as an LS swap if you do it right, or use a new engine-- But, the LS has more scope for further modification. Personally I wouldn't want more than 350hp crank in this chassis, but, that's me-- Do as you please, I won't call you names.
