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...

Lonewolf 06-28-2013 08:36 PM

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
