Considering This

Yah,,,this is one of my concerns as traction with my car now is an issue with 245's and FI,...and the fix adds more cash to the equation with fender rolling and or skirts wider tires and wheels.

How do you know its going to twist its frame ?

Ekanoo is launching his 1k hp/800tq 2j gt86 with full slicks, he never mentioned frame twisting

He never mentioned how much extra steel he put in the car to stiffen it either....what's your point?

Not that much , my point is how do you know this frame will twist without providing evidence

Rather than have $40k+ wrapped up into a frankenstein BRZ with an LS1 motor, I'd just go ahead and buy a C6 Z06 with 505hp or 2010+ C6 Grand Sport with a Dry Sump LS3 for the same price.

The C6 Z06 only has a curb weight of 3130 lbs (about 300 some lbs more than the BRZ/FRS), but much better setup for a high HP motor, and can fit a nice 315 size rear tire out back.

if the purpose was to own a car, that would probably be the smarter way to go. i think anyone considering a swap's idea is to build a car, like a project. it's about the project, not owning the result of it.

Yeah, I get that; it's fun to build projects and make it your own. Just personal opinion, but I have "built" several cars, including a 300whp turbo Civic, 608rwhp Cobra, and a few track cars.

For me, with the first car I built (turbo civic SI), it was frustrating when I had $25k into the thing total (including the cost of the car) and could have bought a bone stock Z06 that outperformed it. I then got an 03 Cobra, spent only like $3-4k extra on bolt-ons, and had a dead reliable 600rwhp monster. I probably spent a tad more in total on the Cobra setup than I had into my turbo civic "build", but I had double the power, and it was much more satisfying.

Personally, I'd rather start with a fast car and do a few bolt-ons rather than a complete build, but like I said, to each his own.

I sold a 2012 Boss Laguna Seca to do this project,..... It was extremely capable and a much better platform (performance wise) than a ZN6, specially with some Kenny Brown parts thrown at it. I want something different. Like I said earlier,...I love Corvettes,....but they are a dime a dozen.

I'd be concerned about the fuel consumption with a V8 in the 86/BRZ.

A V8 with a 50 litre fuel tank means you're going to be visiting the gas station pretty often.

the ls can be set up to get very good gas mileage. the fuel tank size should not be an issue. Driving non aggressively I would expect low to mid 20's around town and mid 20s to low 30's highway. This is a guesstament.

Ok,.....it's official......have struck a deal to do a LS1 swap on my FRS. The only big issue right now is power steering which will have to be be figured out as no one is sharing and no kit has addressed this yet,....everything LS engine wise will be OEM except maybe stiffer valve springs. Talking with the tech at Track Works at Ft.Worth as far as the balance of the car if anything it should improve,....the weight difference engine wise is negilable,... a Tremec T56 transmission going in,.. which is a great deal heavier than the Aisin but, the added weight is more centered and rearward .....see nothing put positives and no negatives for the swap except the cost. Will be selling a bunch of parts on my current setup piece meal or,. as a package as soon as they come off.....built forged engine 9.5 to 1 compression, transmission, turbo kit, DSS carbon fiber driveshaft, Perrin oil cooler, .....etc....etc....to anyone interested.

Additions that were just installed below.

What motor are you going to start with? LS1 would probably be the easiest to find, but LS3's are getting more and more common, LS7 would be nice but they are still pretty spendy.
