I've got a 95 prelude with a 98 h22, from everything that i have been told and learned, the h23 realy is shitty to work with, ive have no problems with my h22 though

 

a h22 civic would rock your teg. b series people always cut it down and the h series people always cut the b series down. everyone likes what they have and thinks its the best thing on the road both are good motors and can do awesome.

dsm's have more problems than i can count. i used to have a 1g wich was the 4g63. sold it though b/c it was just nontop problems. the 4g64 had alot of crank problems though and the worst years were 95-97 if i remember right? also if your talking about a dsm swap then you have the wrong. its' more common to see the 4g63 swapped in.....its the most desired and stronger.

 

yeah that one was a little long but i was just stating my opinion since everyone else did.

 

I'm a huge fan of the h-series. One of the shop cars we are about to put out is a built h22a turbo hatch so I'm in no way hating on h series but I also think the h23vtec is a waste of time for the average person. The extra power gained through more displacement is lost in the inability to rev high. I too am familiar with the big stroke dsm motors but the same thing applies, they are always having problems and are expensive to upkeep if you have to pay someone to work on it.

 

well if it is a waste of time for the "average person" to do the vtec head swap on a h23.... then would it be smart just to go with a turbo on a h23a.... arent they lower compression anyways? (which is overall better for a turbo set up.) the H- series engines are all closed decks so that makes them very sturdy and sleeving a h-series engine would kind of be a waste of money? i gave my boy a h23a for x-mas and we both were curious. he is dropping it in a 95 civic coupe and i have a h22a that i am puttin in a 94 prelude. ..... we are both pretty much set on a turbo set up now.

 

Yes the early h-series stuff is closed deck but the sleeves are FRM which does not like 2618 forged aluminum pistons which is what most turbo and nitrous pistins are made out of. 4032 alloy seems to work with the frm sleeves if the clearances are perfect. The 4032 is as forgiving as 2618 when it comes to FI tuning. Alot of people sleeve h22as just to get a conventional iron sleeve so they can run any piston they want.

 

so you are saying that i should sleeve my h22a....before i turbo it..... for sure? running any performance rods and pistons would mess the block up or what? i was thinking about just getting rods and low compression pistons.... havin the cylinders honed and the block cleaned..... then reassembling it and with that done my engine should run fine.....but is that not smart? and is there any problem with running low compression pistons for like 6 or so months before i can afford a turbo set up? what exactly... and i mean everything in true honesty should i do before i turbo it? i know a lot but i want to double check and learn more before messing my engine/car up..? thanks

 

In my post above I meant that the 4032 is NOT as forgiving as the 2618. As for the definite need for resleeving we are kinda trying to figure that out. We have a turbo h22a hatch with JE pistons (2618 I believe) on the stock sleeves. Everything is running fine now but there is no way of seeing the skirts of the pistons to see if they are galling until it is torn down.

Running the low comp pistons in the motor before turbo won't necessarily cause any problems but don't expect the car to be faster than it was before the build.

I'll try and call Wiseco on Monday and check on how there slipskirt pistons have been running in FRM sleeves and what alloy they are.

 

shouldnt you be doing an all night motor swap?
