[ST185RC]

i just checked the math, FA20-A = A(F20-1)...

PEMDAS!

[pgranberg11]

any interest in developing a kswap? I'm waiting for one of those to come out. kmiata apparently is working on something, but when I saw this I got excited and thought it was a kswap. lol sick swap nevertheless.

Leave it to the Toyota guy to check your math.

Wanna buy my 185?

I'm sure there are parts you may be able to source from the kmiata guys or at least a good starting point on what needs to be fabbed. (not saying you guys aren't great at what you do, but why try to reinvent the wheel lol). They are doing some interesting stuff. Last time I saw them at the track they had the kmiata swap with a transmission adapter to fit a bmw transmission to support the high horsepower k series since the miata trans only goes so far. They offered me ride, but they were still working out the quirks with the bmw trans adapter. lol good luck got be subbed!!!

is it an RC? mine died in a fire, literally.

Honestly a k24/k20 would be pretty bad ass in this car.

[Takumi788]

How about a SR20DET swap kit? I miss my SR.

This car with a Honda engine.... Would have bought it from factory like that

Bone stock 185 with no rusts

I guess since you are in Canada its easier to get an RC

So, are you using the stock transmission or bringing the Honda transmission over?

Which is harder, sorting out where to fit an s2000 trans in the brz/86 tunnel or sorting the connection between the AP1/2 and the subaru/toyota/aisin transmission?
I read somewhere that the transmissions are similar (at least) between the two cars. Interested in how this got addressed. Must be easier than sourcing and then wedging a t56 Magnum XL in there.

FA20s (reliable ones) that are built and boosted are fun, until about 400-450 your trans breaks. Then you need to buy a built trans. The money you spent on a built FA20, turbo kit, and built transmission, could have been spent on a swap. Then, instead of being maxed out, which the FA20 would be at that point, now you have a platform that will max out much higher. We did a turbo s2K for a customer that made 650 whp on the stock engine and trans. The only weak point at that power level in an S2000 is the diff. The FT86 differential has been known to hold 700+. This swap will cost half what a 2JZ swap costs when we're done with our kit. It will also make less than half the power, but then you'll have a stepping stone to build onto later that won't let you down like the FA20 always does.

The stock transmission is "trash" regarding handling high HP, so they definitely will be using something other than the stock one, whether it's the S2K one or another adapted one like a CD009.

240hp > 200hp
greater reliability (perhaps debatable)
9000rpm screamy engine vs. 7400rpm tractor sounds

But at the end of the day, not that much less $$$ or effort than the LS swap. The fact is that in any swap the engine and gearbox hardly factor in the final cost since it is all the details and surrounding cast that consume the $$$

For a daily driver, you would end up driving with less torque in the 2500 to 4000 rpm where most of us drive. I want MORE torque in this band since torque is what pushes you back in the seat. An extra 100 or so lb-ft would give me great linear acceleration from light to light as I conduct my daily driving chores. My current build pretty much gives me exactly that in a 2700 lb package.
