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

 

you will need h series everything... I will sell you the JDM header that you see in my thread for a deal.. let me know..

 

lol comment

 

G23 AWD integra sounds sick right....... you'll see ive already started getting some of the parts that ill need

 

h23 header willnot work..use stock h22 or go aftermarket

 

Like to see this when finished.

ok guys heres some pics..... im about to start to put the engine together

 

and some more pics

 

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..

 

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

 

yeah i still have to clean it up a bit

 

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

 

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

 

did you look at Pirates g build how too thread?

 

no i didn't see it you got the link

 

here's your link: https://honda-tech.com/forums/honda-prelude-4/new-frankenstein-engine-%3D-g23-f23-h23-write-up-long-56k-beware-1046336/

good luck with your build.

 

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.

thanks bro... the build is almost done ill hvae some pics in a few days and im hoping this weekend ill be ready for install

 

Good build,hope to see it finish

almost got the block back together but having trouble with the water pump. i can't find a place that will press it for me... can i just use the F-series or do i have to pess on the H22 cog
