Engine parts list to rebuild h23a vtec blue top?

Ok i just bought my 12 year old son a 92 prelude si for $500 bucks and it came with a jdm h23a vtec engine in it. I tried do some research on what parts I need to rebuild the engine but didn't get a complete answer. If anyone can please lead me on the right path. I know the head is a h22a but what block gasket kit do I need and what pistons, bearings, crank, timing kit, and rods? I heard everything can be h22a parts. Can someone send me a link or website? I can do the rebuild myself just need the parts.

Re: Engine parts list to rebuild h23a vtec blue top?

download prelude manual and study it and sites like hondapartsnow.com have parts lists

you have take it to machine shop anyway (resurface & honing) so you can talk with the professionals there also

everything else is H22 but rods are H23 then you have to think do you want put there Type S pistons or normal ones.. bearings you have to measure after honing and when you open the engine you'll see do you need open or closed deck head gasket there

and then protip: get first some slower car for your son that he learns to drive before youll give em lude to be smashed

Thanks.....

So everything is h22 but rods.. got it...

Anything else I should know?

I just want it to be all stock. Nothing too crazy and then he can do whatever with his own time and money when he turns 16. But I just want a project for him to keep him busy.

Re: Engine parts list to rebuild h23a vtec blue top?

get all the seals and gaskets (remember valve seals), timing belt stuff, clutch kit, LMA's could be wise to change also while youre there

this is a good upgrade (auto tensioners arent that good):
https://www.kstuned.com/products/h22-timing-tensioner

Id let machine shop to check the head & block.

which ecu you have there?
how about transmission rebuild?

oh and if you need to change pistons get H22A4 ones, theyre better than A1's and USDM 99-01 cams are better than ones from previous models
But still I think that the most cheapest way is to get JDM Nippon Racing Type S piston kit than try to hunt good USDM ones, even when those are spare part pistons, theyre really good (everybody uses them - OEM quality)

Thanks...
Yes I know about the tensioner that's a for sure thing...
And according to the guy and from me checking the ecu is from that actual 92 prelude si p13....
I know I need to get the right way. By chance you know which one is best but won't cost much I heard a bunch of different ones.....
I plan on dropping a LSD tranny in btw....
Thanks for the piston info.....

I plan on taking any advice into consideration when it comes time and thanks for any info you guys give.

Re: Engine parts list to rebuild h23a vtec blue top?

H22A4 ecu would be better one for that engine unless you get chipped ecu with tune

Synchrotech has transmission parts/kits

Ya I'll get that way if not I was looking into a chipped p72 ecu that can be programmed to the specific engine or that of a h22a4 so I see which is cheapest.

Also the transmission that's in it right now is from that prelude si and the car has 320k miles lol so ya it needs to be replaced.

Re: Engine parts list to rebuild h23a vtec blue top?

Does anyone know of a complete master rebuild kit for h22a4? I heard mixed things about the eBay rebuild kits that they sell. Some say they are horrible some say they are ok. But if not where can I get a decent reliable kit. Complete though with gaskets and pistons with bearings and oil pump etc.

Re: Engine parts list to rebuild h23a vtec blue top?

My second option I have been looking into is a f20b swap. For 1700 i get a complete engine with LSD tranny, ecu, and wiring harness. Engine roughly 30k miles. Sounds really good. I know some people might say it's not as bad or it can be. I just want a reliable car for my son nothing too crazy so has anyone ever done the whole swap into the si? Anything special that needs to be done?
