HKS Premium Day 2013: FA20 stroker kit and cams
 

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!

:thumbsup:

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.

The cams aren't much larger than factory, but they are likely designed to utilize the different piston speeds of the stroker kit. That would make sense. But the aftermarket should have cams out soon that will not lose any power anywhere appreciable, and help hold the top end a little better.

12mm lift and around 270* duration should do quite well with the high compression. A higher duration cam with less aggressive ramp profiles can probably rev quite well on the stock valvetrain as well.

What I would like is increased compression, same capacity, more power/torque at high revs, don't care about low revs, "because race car".

I'm guessing the cams are for a turbo engine.
Because otherwise why would you bother changing them for such a small change in duration. I'm waiting for 280+ to be released.

Apparently when testing a possible bore increase they found that there was not enough margin to do this safely, hence the stroker kit only.

thats what darton sleeves are for ;)

^^ This. ^^ I would love to see a 2.2L stroker. I have difficulty justifying the cost of rebuilding an engine with all those parts for a measly increase in displacement. For example, I could spend $4k on a 7AG stroker kit for my MR2, which increases displacement to 1900cc using a 7A-FE block and 4A-GE head. Or I could just get forged pistons and rods for the 7A block and still have ~1850cc for about $1k.

I would love to see some cams making peak power up to 220Hp.That be nice and hearing the cam notes on the exhaust exit

bore and stroke for a 2.4 OR AT LEAST 2.3 PLEASE...

Any updates on this?

This engine will see a lot of development,....just stand bye.

???
What else is there to keep this car NA and get the most power besides this stroker kit, a tune, pulleys, intake, exhaust, downpipe, light weight rims, light weight flywheel, ditch junk in trunk, carbon drive shaft, bigger throttle body, headers, dry carbon exterior parts, light weight battery.

am i missing anything to make this car faster in a straight line?

i cant seem to find any other parts to make power

Final drive

so not much for NA right now

Have a look HERE

(sorry to bring up an old thread, was looking for it for another reason then saw this post)

BUMPING AN OLD THREAD! where r those cams & stroker kit?! :(

HKS Stroker + HKS GT SuperCharger??
 

Light weight racing seats or better yet, bucket seats(5kg for super light ones).
Stock seats(in my car at least) on the BRZ's are around 19/20kg.. EACH.
Easy 10kg lost per seat imho. I need to make the switch soon also.


As for the stroker kit, imaging if this were paired to the HKS GT Supercharger kit.. I wonder what kinda GAINZ would be achieveable from such a combo...

How i can buy this camshaft ?

I think I may have missed it...but whatever came of these parts?

Bump.
Any updates?
I'm keen on price if anyone knows(full kit)

i think they're the same parts that are being used for this evasive motorsports build. http://www.ft86club.com/forums/showthread.php?t=65202

here are the specs but i don't see a price anywhere
