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

[shingles]

Cracks me up... people use all kinds of excuses as to why not to swap an LSx into xyz. CoG, angular momentum, too much power for the street... who cares? I used to be one of those that looked down on the LSx. But the fact is, it IS a great engine. In fact I am contemplating a swap into my e30 chassis. And really, do you think the average driver on this very forum can tell the difference between the CoG, etc etc on the track, much less the street?

I mean, if the car is so perfect, why are these same people buying cheap coilovers, swapping springs on to stock damper, getting sway bars, exhausts, intakes, etc.

It's a hobby people... you like x, others like y. Stop the hate already.

An LS swap would require a different transmission, rear end, suspension, exhaust and brakes at a minimum. Not worth it and obviously the car would be ruined. Build a low compression FA20 with lots of boost instead and leave the GM trash where it belongs.

Lol so much ignorance...

I have had 2 people buy the LS3 engine and trans combo when they were on sale. So it looks like at least 2 more will be running them soon. Unless it was for a different car I didn't ask. I really like the idea of 430hp. It is however an expensive swap that will take a lot of hours to complete.

I've talked to my mechanic who is an ls fan. The biggest unknown is the ecu. Getting a different motor to work with all the other oem systems is apparently bloody hard.

Getting the motor in and running isn't hard. Being a boxer engine bay, we've been blessed with ample room.

I'm reintereeted in this now, as soon as I saw 60lbs.

FI add 30lbs.

The beauty of modding is that we're all free to do whatever we want so long as the bank account doesn't disagree. If you happen to be a purist that's fine as it pertains to your car but there is no need to get the panties in a wad over other people's choices.

I do have to laugh about the " lazy pushrod powered" comment. I can think of many words to describe the LS7 that sits in my garage next to the FRS and "lazy" isn't one of them.

The brakes on this car are just fine for 400hp turbod cars but you think they need to be changed for an ls motor?

Exhaust will be custom and it will be cheap to make. All you need is two flowmaster mufflers and some straight pipe. A shop local to me does it for a few hundred bucks including the cost of the mufflers. SO not any more expensive than the 1500 ark grip "performance," exhaust

Building a low compression fa20 and buying a turbo kit would cost somewhere in the neighborhood of 8-10k with labor and tuning new clutch etc

which is about the same amount it would cost to buy a used LS motor, and tranny, drive shaft, wiring harness etc

You obviously have nothing insightful to add to the thread so go jerk yourself off in the fa20 fanboi section of the forums.

"obviously the car would be ruined" shows pure ignorance. What would ruin the car? The instant torque? The insane reliable amounts of power? The comparable gas mileage? The nearly identical weight distribution? The additional 80 lbs?

You wouldn't HAVE TO use a difference box/shaft/diff. You could adapt the box to an LS easily enough.

Yep; if you look at WGP they are using the OEM diff.

This is almost entirely wrong. Custom driveshaft isn't anymore expensive if you're already planning on CF/AL and will mate to the factory rearend. 60 pounds isn't going to drastically alter anything as far as suspension configuration---sure you can dial it in better if you've got adjustable, but I've seen plenty of people with other mods that add more weight under the hood without alteration. You're saying an LS swap requires brakes, but not the low-comp balls-out turbo build?

I believe the current LSX swaps DID use a T56 transmission instead, but I've seen plenty of these swaps in other chassis where someone makes a billet bellhousing adapter, etc and the stock trans is retained.

A new FA20 engine costs what? $7K? LSX is cheap and reliable at vastly higher power levels, and I could have a HANDFUL for the same cost as replacing the factory 2.0. I know what I'll be doing in a few years, but to each their own.

I just started releasing information about the Hydra EMS for the FRS but motor swaps have always been a niche we work within. You can drop in an LS V8, Subaru H6, EJ257, or Supra 6 and not have to touch your OEM wiring nor lose ABS, power steering, stability control, dash function due to fu CAN bus compatibility.

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.

Thanks,

The scenario above is ideally the ethical way to do the engine swap, especially if the chassis has outlasted the engine and the manufacturer no longer offers parts & support for the engine.

id rather see a 2jz or a rb26det
