I believe all they did was shot-peening for the gears. I wouldn’t expect significant improvements to strength in those gears, but maybe all the little changes to all elements in the transmission will add up.

IAG getting interesting…

I was hoping someone would look at making a "kit" to make this relatively simple. Question now will be whether this will be a kit for a complete motor swap (and with or without all the ECU, electronics, etc.), long-block or short-block.

Fingers crossed this isn't just vaporware, because my ideal path is still a 2.4L swap rather than forced induction... ;)

I would love to keep my Edelbrock and just have the 2.0L heads machined and keeping using the SC. If not, I’ll just do a built IAG 2.0L.

Oh yes baby! Come on IAG. I will drop some coin on this if its cheaper than the K24 swap and dose not need significant re-wire etc...

My custom twin supercharger will likely bolt right up to the fa24, so if the swap becomes viable with or without the fa20 heads, it might be a go for me.

Although I would prefer to be able to use the fa20 heads, since I already have a spare set, could sell the working fa20 in the car and would only have to pay for an fa24 short block.

4th gear vs 3 gear. Also He has a vortech which nothing is home down low but it does show what the new 2.4 can do. Can't wait to see it with Tune and e85 only.

Additionally the SC car only made 240whp on 91. Add the widebody and big heavy 3 piece IG wheels the result seems legit.

Any word from IAG about progress?

I emailed them maybe a month ago, and they wouldn't officially say they were even working on it. They just said "we're not working on anything for the new BRZ/GR86 yet". ;)

The supercharger should bolt in place on the 2.4 using the 2.4 heads. The exhaust manifolds bolt right up from first gens.



From what earlier reports have shown, the crank trigger wheel isn't compatible with first gen ECU's, and it looked like the design is different enough that you can't just swap on a first gen trigger wheel. It looked like a second gen ECU is needed, but if someone is going to make parts that work with the first gen ECU and physically bolt to the 2.4 then it could get interesting.

Supercharger bolts to the intake ports, not the exhaust. Real test is the first gen intake manifold bolting on.

Exactly. The intake ports are different
