FA20 - A, Thats F20 Quick Math
 

We've been up to no good! This was a complete mock up we did to make a mount kit. Mounts are in production!

Up next will be K Series mounts, then we will finalize our Honda engine swap ECU plug and play package! Stay tuned!

Saw this on FB, pretty cool swap.

Schweeeet :D

TELL EM MANS NOT HOT

Sacrilege!!

But if you put in a Honda J-series...the newer ones..we may actually save weight perhaps. And I know them pretty good and they are reliable as hell.

I am all in then baby,

Wow, that's the cleanest swap (of an s2k engine) I have seen!!! Nice work!

I loved my ap1! That VTEC song!

:w00t:You guys are tearing it up!

I do like the S2000 despite the Jeckyl and Hyde personality. Not so sure I would deliberately transplant that personality into the FRS.

Power gains would only be found above the VTEC threshold at 6000 rpm?

I am not saying that it is a bad swap ( looks well executed) but I would need to have the value proposition of this swap explained to me a bit more.

K swap the world!

Jeckyl/Hyde personality is purely a function of VTEC transition at 6000rpm. Tune to move it to 5000rpm or wherever torque is equal on either set of lobes eliminates the stupid VTEC "kick". In my '01, I never notice it because I'm almost never in VTEC on the street, and always in VTEC at the track :)

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

Lol!:cheers:

Cleanest mock up?

The value of this swap is the same value of every swap we have done so far. They're all the same reason: They are a building block toward something better. 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.

I wonder how differently it will handle compared to the fa20.

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

PEMDAS!

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.

next on the list

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. :cry:

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

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

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

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.

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.

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.

The F20C swap will be with the stock S2000 transmission. They are decent up to 500-600. And the best part is, unlike a CD009, T56, etc, it fits in the stock tunnel without the use of a 10lb sledge hammer!

Will the k20/24 be using the s2k tranny aswell?? If so im gonna start finding a motor and tranny soon..... also for ecu plug and play package will you guys be using Motec or Kpro ???

If you're using j/y parts maybe engine/trans costs aren't all that significant. But I recently put brand new forged stroker LS3 and T56 Magnum transmission in the FD and I noticed the outflow of $$$$$! That was after the old j/y LS2 swap developed cracks in #7 piston ringlands and the j/y F-bod T56 in addition to being balky in general started popping out of 3rd at the track at the most inopportune times :(

Meanwhile the engine and trans in my '01 S2000 are fine at 253k miles after 10 years of daily-driving and many track days.

I would not hesitate to swap a used j/y F20C/M6 into a car for street/track fun.
I don't think I'd do it with an LS-swap again though, for my usage.


In reality, surprisingly to me even the '17 BRZ with 4.3 diff doesn't feel any more "punchy" for the situation you describe than my '01 S2000, maybe less so. Partly due to the AP1 trans being shorter-geared (numerically higher) but also due to the fact that you're already running into the FA20 torque dip by 3500rpm, whereas in the S2000 the torque is pretty flat up to 6000.

IMO F20C (or F22C) into FT86 should be a pretty brilliant swap. If it came like that in 2013 I would have bought one then instead of waiting til just a few weeks ago!

I'll probably just save up for this lol

S2000 Transmission is the likely candidate. We would do something similar to our MoTeC package where the factory dash, power steering, abs, etc all work :)

Sounds greats, when will we get to kno pricing on the plug and play package? Gonna start lookin for tranny and K24 asap been waiting for this kit since the 86 was out.

If I keep my BRZ...

Guilty as charged. I do miss my RC quite a bit but I don't think there's any left in circulation to buy anymore :(

Our normal price on the 2JZ and LSX MoTeC kit is $5895. We are trying something new to attempt to shave the price down significantly without losing any of the benefits, it will take a little extra time for us to develop but it will be worth the wait for the consumer hopefully :cheers:

Perfect cant fucking wait!!!

It would be sweet if the price for your kit plus a used engine/tranny was sub $10k +/- for a DIYer looking to do their own install...not including tidbits and incidentals like engine/tranny tuneups, small fixes (like broken sensors, hoses, etc), new parts (like clutches/flywheels) and after the sale of the stock motor/tranny. This would make a swap comparable in cost to FI on a built motor, but with more reliability and probably higher power potential.

looking at the m150 data...
 

Once this is developed, wouldn't the same harness be usable for the sr20det as well with some sensor plug changes?
