has this been posted yet? according to this site HKS previewed a stroker kit and cams for the FA20 engine.

HKS stroker kit: keeps the 86 bore and increases stroke to 90mm. comp ratio is lowered 10.5:1 for boosted applications.

Valcon camshafts: IN 260 degrees (stock is 252) EX 266 (stock is 260), lift is 12mm (stock 11mm). because you need four this is probably gonna cost a lot.

Good to see some engine work finally. I'm a little disappointed the stroker kit lowers the compression... What about those that wanted a full n/a build?

guess we'll have to keep waiting for high comp pistons. with d4s, i wonder if they'll be able to make pistons that are even higher than 12.5:1? it's cool though to have confirmation that the engine can be stroked to at least 90mm. the F22C with a similar stroke redlines at 8200 rpm. i wonder how the F22C's torque curve compares to the FA20?

Not sure on the F22, but here is a dyno of a stock F20 (red line) vs a stock FA20. (pink line)

hmmm since the fa20 already makes 160 lb/ft, with a stroker can we expect even more torque than the f22c which makes 162 lb/ft? what would the displacement be at 86x90?

IDK how much all of this will cost, but i love it!!!!!

Nice to see some engine work. Too bad this will cost $4k. I'll wait for more options hopefully from kelford, bc and cosworth.

I am disappointed as well that the pistons lower compression. But happy to see options like this arriving. And probably lots more options to come, some of which will keep stock or higher compression ratio.

I like keeping a square block but glad to see this out.

caaaaammms only big upgrade i want for this car honestly. ive done enough turbo setups for now

Finally cams and they arent much different than stock. I'll keep my money until bigger gains can be had.

Surely getting some high comp pistons onto this setup wouldn't be that difficult?

Finally cams!

Kinda sad really - i was hoping to see the HKS stroker toss it in the 2.2L region.

But yes, the old addage is that theres no replacement for displacement. With displacement comes torque. Dont expect anything insane, but i would estimate about 10-12 more hp and 8-10 more torque throughout the entire rpm range. coupled with the cams and some head work, 30ish more hp in the 8000 rpm range.
