If you are looking for a good turbo-able stock motor for a low price, I think the the Prelude S/Accord F22 motor is a great choice.

 

if you would like i have a complete h23 (minus starter/dizzy cap/ac/a few small odds+ends) that needs a rebuild(you could just save money and build it up for turbo since that's what you'll be doing anyway, that way you're not paying for a working motor you'd still have to build), i'll sell you it for 200+shipping

 

I would do a search for more info. There are so many variables to that question. No matter who you ask and no matter what engine you put in you will end up spending alot of money. So it's best to do a thorough search before you even start.
The first step is to determine what kind of numbers and what application you are looking for. That will help you determine what engine family you want.

One word of advice... do it right the first time, and think before you start buying.

thanks for the advice

 

Compression isnt the only factor you want to consider when looking for a good base for boost. The H23 isnt a good choice for turbo IMO, the F22 is an even worse choice. Both are blocks with a lot of cylinder pressure to start with due to the large stroke and fairly short rod. Add boost into the mix and your not leaving yourself a very wide margian of error.

The large stroke of the H23/F22 blocks isnt the ideal set up for turbo. Generally you want a bottom end with a higher r/s ratio for reasons Ive covered time and time again on this board. Stroke isnt necessary for boost, all the HP and TQ you need is created via the turbo. All your doing with stroke is sacrificing efficency which isnt something you want to do with a turbo motor.

The F22 block is a big waste of time. Unless you are going to sleeve it and run a bore size of at least 87mm (if you plan on running an H head) your going to put a lot of effort into building something that "just works." Ive covered this subject as well a few times in this forum as well.

So for boost, either a H23 block with H22 crank and rods or a straight H22
