Possible for our FA20s to have the Torque Curve of the FA20DITs?

Ask moto east but think you can use it on stock with normal pulleys! Of course they will prob recommend a built motor,but from what I remember reading; they ran it for a year on stock motor. This is what I'm prob coining to do! This or jacksons racing with 4.88 gears! Should give it a nice kick down low and still have about 150 mph top end if it's redlined to 8000. Should be plenty for this car

I personally hate this cars first gear and im at 4.1, i dont understand how anyone would want the gears to be smaller.

Yea figured first gear will be useless just trying to make the other gears more responsive. Don't know first is boost then I'll see how things go maybe no gears at all. "You don't know unless you know"-

Oh and I was thinking of raising first and second gear with the Cisco transmission set. Did a little figuring and should make fist and second close to the 4.56 gear ratio if you use the 4.88 gears and transmission set. So maybe that with help out!�� And make it close ratio tuboot

Did more research an apparently the kit is capable of 500+whp? If that's true, I'll most likely be going this route, I'll definitely look to see if it can be used on stock with a less agressive tune (:

Don't think you'll see quite 500 but a little over 400 maybe 450

So correct me if I'm wrong, if I go with a bigger twin-scroll turbo as I'm beginning to sense I'm going in the wrong direction, it would give me a good balance between low end torque and good power on the upper limit with headroom to grow with a built motor?



Loving the idea of this kit, although it is a bit more expensive that I'd hope to go, definitely an option

Full race is pricey right off the bat, but you get a monster manifold that will take track abuse. This isn't cheap to produce. Their kits also are as complete as you can get with an EFR and all the bells and whistles. Any other kit will cost close to the same when you spec it with the same level of components.

No SC kit will hit 500whp. Not 400 whp on a calibrated dynojet. Turbo only to hit anything above that. That isn't to say a 400 whp SC isn't a complete blast on the street. The instant response makes it feel like a v8. But a 500 whp turbo is a whole different beast altogether. Once you cross that 400 whp threshold you have to factor in the transmission. If you aren't willing to do a swap ($$$) or at least upgraded gears, then you won't get to use the 500 whp very much. We know, we've done several 500+ whp builds and most of them end up going through a trans pretty quick. In the end it isn't a big deal to go through a stock BRZ transmission once a year now that they are about 500-1000 used, but it is still rather inconvenient when it lets go as you're walking away from a 911 turbo or a modified GTR.

I ran a 28RS and loved it, peak torque was 4100 if I remember right, that was also with a .86 hot side.

@moto-mike give us a transmission solution!
