and both the 4g64 and 2.4+ size engines shouldnt really go past 8k. the pistons are moving too fast and heat up too quickly, so high RPMs are not good on them.
No the 4g64 and 4g63 bore is pretty much the same . The 4g64 as a taller deck height aka the cylinders are longer.

Not that I know of. I feel it is really too much displacement for a 4 cylinder. Possible bore and stroke for a 2.6? I wouldn't go north of 2.3 with this engine IMHO.
Toyota have a 2.7L 4 banger.
This is definitely an extreme build. I don't see the point of it thought. Most of the high HP Evo are 2.0-2.2L. If you really want something wicke for the road course, you can always get a well built, proven 2.0L engine and have your tranny build with really tall gears.
We have some dyno sheets around here somewhere. Ill see what I can dig up.

low down torque and response is the key and what we should have in the end product .
I have a 2.16 stroker now to be exact , and rev to 7000rpm with it - dont need anymore because that also has awesome spool up and this one should be even better but just produceing more power with the bigger turbo and displacement

Your not on the wrong track just......derailed. 4g64 has a 86.5mm bore with a 100mm stroke, the 4g63 has a 85mm bore and a 88 mm stroke ,the main difference has to do with the significant increase in stroke, thinning the walls 1.5 mm will make it weaker, how much so I am unsure.
Your comment about why you cannot rev these motors that fast is due to the change in the dynamics of having a significantly different stroke/rod length combination, and has NOTHING to do with pistons heating up too fast.

Not an evo but a an 2g. My buddy just got a 2.4 and He said he order the crower stroker making it a 2.6. I am pretty curious on how that turns out myself

Will it be a twin scroll set up?

That's nuts. I've never heard anything like that. Can you post where you read that. Not calling you out, I'm just curious.
