Honestly, you should stick with doing a turbo motor swap, those things are lethal when setup right. If not, the 5.3 might be a better choice depending on how much weight you can save. Weigh the stock motor, then select your motor based on weight, so the car will still handle like stock as far as weight ratio. Good luck, post some pics when you get it.

so wait a second. you want to put a 5.3 LS motor in a supra chassis?

now its one thing for the RX7 guys to do this swap, because the stock rotaries in those cars are crapola, but theres nothing wrong with a supra motor. if you want it to haul ***, and you want to do a motor swap, why not just pick up a 2JZGTE. you can get them turn key for around $3000. you can easily get 500 hp or more to the wheels with stock twins, stock fuel system etc.

there are even turbo kits available for the stock NA motor that make over 400 to the wheels.

unless you just have more money than you know what to do with, and are dead set on the dare to be different category, i would seriously look into staying with the 2JZ platform, they are awesome motors, with awesome potential.

and for your "stuck in the 60's" ignorant uncle, show him this. 1000 hp - stock motor.

That would make a cool LS1 swap car!

It's stick with an aluminum car motor to keep the weight down.

Sell the body to a ricer and build something else, or replace the 2JZ with a new one and turbocharge it. I have 1 buddy with a 9 second '94 TT and another with a 10 second 2JZ-GTE powered Lexus SC300. Those motors are simply ridiculous, and the Supra is probably the one car on earth that could be considered "downgraded" after an LSx swap.

Not to start a huge LS1>Supra argument here, but I wanted to ask why that 1000hp supra only ran high 9's?

I have a friend in the low 9's with WAY less power... is it just the powerband on the motor or is it harder to make the supra chassis hook?

well i agree that that is the million dollar question for supra owners. although the near 160 mph trap speed is impressive, everyone seems to have their own excuse as to why the et's dont quite match. maybe the independent rear suspension...3600 lbs...etc. the 6 speed cars seem to require a bit of finesse off the line. you have an engine/turbo combo that has a hp/tq curve that looks more like mt everest on paper, usually not reaching the meat of the band till 6500 rpm, and only lasting untill 8500 or so.

my point was that you can get an awesome real world vehicle with the parts it came with, much easier and cheaper than an obscure, intensive engine swap.

So are you seriously selling the supra?? I might be interested in it, shoot me an email with some pics. As for the supras monster dyno numbers, yes, they are more of a peak power not a real powerband number like our cars will have when turbo'd. That is why they are highway killers, you only use 4th-6th in the upper rpms... There is nothing like big V8 torque though, especially combined with high HP numbers....

Talking LS1 Supra............

If it were me, I would do it in a heartbeat. You obviously know a thing or two about LS1 engines, stick with what you know. Build it!! I can hear the die-hard supra fans whining already.

why spend the extra cash to buy a 2JZ, modify it, and tune it, when you have a perfectly good smallblock ready to be turbo'd? You can easily match the potential of the 2JZ for a smaller investment, whether you're looking for 500hp or 800hp-especially in your situation when you have much of it readily available. Plus much more of the powerband will be usable. Now that i've started paying attention and see that you are selling it, forget it!

I'd definitely drop an LS1 in there, turbocharged of course. Those Supra guys would be all excited how the new "prodigy" supra is hanging the tires out of the hole and running great times -- but sounds "really funny"

You got the car for nothing, you have a 5.3 "laying around", you know your way around a toolbox. I think this is called a "no brainer".
From the responses here I would do it for no other reason than to **** the Supra guys off. (I'm cranky, it's Monday)

Go for the 5.3 Turbo set up i guarantee you can make 500 hp easy and unlike the 2gayzgt motor or whatever you won't have a dyno sheet that looks like "Mt. Everest" as somebody mentioned, also you won't become one of the infamous Supra drivers who constantly find themselves saying "wanna race from a roll?" Not to mention you can make that 500 hp without running 22 pounds of boost or more. Its always cool to have something unique and why not put the engine you have lying around to good use?
