ok so im getting ready to dorp in a G23 in to my integra and just thought id see if you guys had any tips for me.... ill put up pics later. i went with the F23a1 block bored to 87mm K20 pistons and H22a1 head with stock valve train.... (for now) im using my tranny thats in the integra now and my CR should be round 11.7:1 not sure what the HP will be but when i know y'all know to. thats not me in the car its my buddy that helped with the b18 head gasket

Sounds interesting hurry and get her done.. i got pretty much the same setup but the f23a5 block with prelude type S pistons... and pretty dope headers... the head is a JDM h22 stock but i wanna dyno soon and we can see whats up..I don't recomend the k20 pistons.. My compression is around 12.5:1 and that is with the stock h22 clearance .006 out of the hole with my custom copper HG... im sure I could mill alittle more to raise it but mine is a daily driver on pump gas.... So i will be waiting so see your results....

Keep it Pimpin Pimpin...

i got after market k20 pistons from wiseco witch i hear is a good brand, as far as the exhaust goes i got a manifold from an H23..... i pretty sure a B-series wont bolt to it so do i need the down pipe from the F-series or the H-sreies??? and as the build gets under way ill take some pics and maybe a video when its done... im also thinking about doin an AWD conversion i have the know how i just need the parts

cdownin

Aren't k20 pistons 86 MM.. you must be getting after market oversize ones correct .. Make sure you clay your engine because the way the Heads are shaped are different.. there various threads where people do this and bend valves.. And nice pics good job cleaning the head and block..

turbociv910

your head is not finished... i hope you know that.

DA9racer

yeah i still have to clean it up a bit

turbociv910

.. this is the proper way to machine the head for a G build.

DA9racer

ok thanks ill have to do that.... is there an easy way to do it myself or do i have to take it back to the shop

turbociv910

hmm.. interesting. (saving pic)

Looks good to me. The extra machine work (red arrows) was unnecessary though. The oil's going to drain straight out of the holes in the head into the over-sized returns in the block. Another .050" is not going to make a whole lot of difference. Good luck with the build. Be sure to retune and post results.
