also, the f23 has a floating wrist pin, while th h22 has a pressed wrist pin.....still no info on the f22 wrist pin. If it's the same as the f23 then the 2g DSM pistons have the same wrist pin size.

holy crap... I've been debating on wether or not to try to find some oem pistons to do this with... it was just a crazy idea I had a while ago, I didn't even think it was feasable... Good thinking hatchninja! Why are honda people so ghetto...?Shift_BOOST

its the HMT way. its fun to be cheap sometimesOriginally posted by 92exComment

Most Honda people aren't ghetto, it may look it, but to me it's innovation. It's not always about looks, it HAS to perform! Hatchninja obviously spent some time thinking and this amazing idea came out. Pure genious. Can't believe how innovative you guys are!
There's nothing wrong w/ HMT style, we're not all made of money! ^ That's right Eric!

been researching like such a nerd!!
ok....apparently there is a 2.4L n/a version (stroked, same 85mm bore) of the 4g63, the DSM guys build a wicked 2.4 turbo motor using the 4g63 pistons but they get a machine shop to move the wrist pin location.
So, if the wrist pin location is too low, resulting in too high of compression, it can be moved up to drop compression.
But if it's too high, ultra low (unusable) compression, i don't know if it can be moved.
I revealed my spying on DSMtuner.com and asked them how much the stroker guys move the wrist pin.
ANSWERS SOON!!!!H.S.A.E.

middle of the wrist pin to top of the piston measures 35mm. The wrist pin itself has an ID of 15.2mm and the pistons wrist pin hole is about 21.2mm. And i must be on some natural high cause they are dished and there are 4 reliefs lol. I'll post pix later. Anything else?Knowledge is power...in EVERY sense of the word

just found this on DSMtuner
so here's what we got so farthis prolly sounds like a stupid question but does anyone know how to remove the connecting rod from the piston from a 2g car? im feeling pretty stupid, i also might just be missing something

The wrist pin needs to be pressed out to get them apart.

4g63 (2nd gen) piston
85mm bore
22mm pressed wrist pin
f22 piston
85mm bore
22mm (i think, f23, h23, and h22 are) pressed wrist pin
funny that i now know more about the 4g63 piston.H.S.A.E.

yeah, do you have any f22 pistons (and/or rods) to measure in comparison.H.S.A.E.

pm'd those guys....pretty ironic that we were able to measure the dsm pistons before the f22 pistons.H.S.A.E.

my brain thinks so ghettofabulously. It's crazy. I'm always like "there has to be another cheaper way to do this"Originally posted by 92ex

http://www.ariaspistons.com/products...om.pistons.pdf
Bottom of page 4 gives some info on the F22A pistons...middle of page 5 are the 4G63 pistons.
May not be what you need, but I figured it'd help.

hmmm
i may have to try this swap... i already have a set of 4g63 pistons in my garage.Comment

cool idea guys...keep the research going! if we can figure out a way to get stronger rods ::cou-CYRO-ough:: we can have a built block pretty damn cheap!Comment
