Wanna race?! We can put your theory to the test.

Sure! Autocross?

[sweetfrs]

has anybody here even driven a frs or brz with over 240 whp? most of you will say no. till you do this you don't need to even think about 2jz or v8 swaps

[Dipstik-sportech]

Sure, I'll be sure to install my r comps. You do know the throttle isn't a light switch right? I don't have to use all 500whp from the moment I touch the throttle.

[Pete156]

Yes, I do. Have you run autocross with this setup (In the rain)?

[Dipstik-sportech]

Not in the rain but I have auto crossed it on my 560 tread wear nittos and guess what..... I beat all the stock FRS/brz's and placed 2nd in the street tire class. It's all in how you use the power and how good of a driver you are to be able to control it. Any other questions?

[Pete156]

I haven't lost to a stock 86 either, with street tires. That's not saying much. If you live in the PNW you pretty much have to run in the rain.

[Dipstik-sportech]

We lucked out and none of our events were rained out. Off boost my car makes no more than stock power so it stands to reason, on part throttle it will be as easy to drive as stock.

[Reaper]

This is why the lsx wins over the 2jz. More usable power. A lsx frs would probably be easier to drive than my 450+whp fa20.

[Pete156]

I imagine when you do come into boost on an autocross course it must take some extreme right foot control. Good on ya for getting out there and performing with that setup.

[Dipstik-sportech]

It's a crowd pleaser that's for sure on the street tires.

[Reaper]

It's all in the tune. Boost by gear, rampable boost and per gear traction control are all a click away in ecutek. But a large displacement na v8 will always be easier to drive then a fi 4 cylinder of the same hp. Trust me, my first tune made power too quick with my gtx28.

To say there is nothing left of the 86 is also not even remotely true. The only thing different is the engine and trans.

Oh well.......... steps out to shop to actually build cars.

Ha! The axles, differential, suspension, drive shaft, brakes, and all associated components will need work to support that much torque reliably to the ground. Essentially only the body of the twin will remain...

If you think these stock parts will hold up under that kind of stretch then you have a rude awakening coming

If it's just for the challenge of hitting 500 hp yourself then have fun.

Why do you need a sports car when a Prius will do? Why do you need a car at all when a bike or your own 2 feet will do?


See how stupid that sounds?

Kind of like those two guys working on their 1-2 year long "2JZ Project". @slicktop @Drift&Drag Is it really worth it to dump that much money and time into this chassis?? Not only that, but what about utilizing the power behind the build. Both engines are over built for what this car can handle. SMFH What a waste!! lol

Considering the size of the tires you can stuff under this chassis and how beefy the suspension really is, you're simply 100% wrong.

Naturally aspirated high displacement engines FTW

Sure, if you like single digit gas mileage

Depends on gearing and power levels. I've heard this line before and watched Supras absolutely destroy them...

Still, if you want to go fast it's hard to make a compelling argument against bikes. Unless, of course money is of absolutely no concern.

Depends, with how many trucks and SUVs with idiots behind the wheel around here, a bike is a death wish...

Also, basically you're swapping a Twins body onto a GM car, almost nothing except the look of the car will remain in order to put that kind of power down on a consistent basis.

You make it sound like you can't get decent sized rubber under this car, and that it's magically going to snap the chassis in two. It's been consistently proven the chassis is very overbuilt on this car.

Maybe on a car without any tuning that gives full boost in first gear. We've been able to get real traction control with different boost levels per gear for decades now...

Not to be off topic here, but I feel this car to be even more fun only needs 20-40 more hp. I'm surprised nobody has done an FA20F swap from the new wrx or jdm legacy gt or something...

Won't fit, would make less power than adding FI to our FA20 because of the dual fuel system we have, etc...

- Axles I dunno of failures from power (lots of failures from being too low, just like the WRX/STI crowd). So what, get beefier ones.


- Differential is the same size as the old MKIII Supra IIRC, so it will take it just fine. Oil cooler will help on high speed runs though.


- Suspension is fine (unless of course you're putting in a much heavier engine, so then you need springs to match)


- Drive shaft is fine and if it needs to be stronger it's no big deal as everyone is swapping them anyway.


- Brakes, there are bolt on options for this and people with stock power are even going to BBK's so I fail to see your point.


THIS CAR WAS DESIGNED TO BE TUNED. They knew all of this stuff would happen and it's why the aftermarket support for this car is huge. Want to stay stock? Good for you, but you're in the minority...
