Cool! Good luck with the build. Still keeping it boosted?

akoutmos · Oct 1, 2012

Still debating that. Gonna build the motor bare bones at the moment as a proof of concept. If it doesn't work i don't wanna spend too much money. That and i will be able to tune the motor for low comp and share the base map if people want it.

changing out the pistons for low compression ones? g23 boosted would be nice

akoutmos · Oct 1, 2012

With the H22 head on the F block, the comp ratio goes down to like 8.45:1 (according to the comp ratio calculators). Which would be good for boost. On the other hand i wanna dabble with a high comp all motor build so i can get a little experience with that too. IDK yet what i'm gonna do. For now i just wanna put the G23 together and make sure it runs

BTW anyone have an H22 header for the cheap?

I've been considering this myself. I would like the dohc with vtec and all that, but i want the solid bottom end of the f23. I'll be keeping an eye on this thread for sure.
Why not dabble a bit with higher compression forced induction? isnt that a little less reliable, but a lot more power opportunity?

DarkSideAccord · Oct 1, 2012

i believe the pistons from the rsx type S works... easy way to bump up the compression

Pretty sure ur right. K20 pistons fit in the f block supposedly. I'm following Bolis' G23 build guide. It's the link in the first post. Did you follow pirate mcfred's?
