There's a 92 prelude auto tranny being sold on craigslist near me for dirt cheap, I only care about the motor in it. I've looked all over the internet and forums and found that the 92 auto tranny is an h23a1. Now I was hoping for the h22a but both motors are closed deck which is what I want. And from what I've researched it seems the h23a1 is more for vtec N/A than turbo. BTW I'm building this motor ground up, everything to handle turbo with no worries. But if I'm building the motor ground up will it matter which motor I get? I'm going to talk to this guy tomorrow (saturday the 17) so quick feedback would be great. Thanks and I'm only posting this cuz I need some experienced input quick, otherwise I would research for a couple more days or over the weekend and really narrow it down. Thanks again.

 

H22>H23

FYI, H23A1 = No VTEC.

 

you can always get a h22a head.

 

There's more to it that that buddy.....
Compression comes in at 9.3:1

 

ok so forget this post cuz I'm now gonna do some more research on the f22 motor cuz i've been hearing it is also an option. I plan on building whatever motor I'm getting for a 9:1 compression ratio with everything being rebuilt from ground up. I wish someone could make a thread on all the possibilitys of each motor and the pros n cons. But for now I will do more n more research because a lot of money will be involved in this project and I want to do it right the first time. And my bad on the h23a1 saying vtec, I know its not and that was noob, but thanks.
