Okay, right now my car has the origional H23 w/ intake, header, exhaust, cam gears, stage2 clutch, aluminum flywheel, crank pulley, and plug wires. If I swapped over to an H22 (due to high miles on the H23) would these parts all be transferrable? Also, I have another H23 from my last Prelude (r.i.p.) When I researched this last year, it seems like people said that the H22 head could be put on, but that it's not even worth the time or money. But since i've been looking at posts on it this year, people are just like (yeah, just throw the head on there & install the VTEC oil jets for the bottom of the pistons. Well, I definately have the time, and the extra H23 block. Is there a company that sells a gasket kit made for the conversion? Has anyone found a website that has a step by step of the conversion that I could look over? thanks!!

 

i dont think the tranny will be a direct fit from h23 to h22, not sure.

 

trannys from the h22, h23 and f22 are all swapable

 

yup

 

i have a h23/h22a frankenstein motor in my 93 prelude but it unfortunally it just got totalled out and it was a bad mofo. i have time slips for 13.4 sec 1/4 mile on 18inch Nitto neo gen tires. it is the baddest honda motor conceviable i give damn what anyone says or thinks. i will help you out or give you any advice you need if u want b/c trust me no bullshitting,off top u will love it the torque is absolutly amazing and when Vtec kicks in it is pure evil, u just have to watch ur redline if u keep stock internal in the h23 block. well got to go but hit me up with an reply or email lude_crs_9398@comcast.net - the 93 is for my block and 98 for the head - what can I say prelude rule

 

lude_dude_9398 your saying your h23/h22a frankenstein is pulling 13.4 without turbo?

i was also thinkin about doing a frankenstien setup with turbo though

i read a previous post about some1 who did it and i was looking for a vtec head and some other parts to do it.

 

i've heard that if you put a h22 head on a h23 block, it's not good for the life of the engine. Cause the redline for a h23 is lower then the h22. The h23 isn't suppose to rev as high as the h22. Same goes with the integra ls-vtec engine. If i were you, I would swap a h22 in there and start fresh again.

 

I heard the h23 block is already plumbed for VTEC, unlike the popular LS/VTEC and CRVTEC hybrids... external oiling is NOT required.

all you gota do is pull the plugs out of the vtec oiling channels


woo hoo

after a couple weeks of research i now believe this is a good idea

 

the h23 block is the toughest built honda motor for one reason. the block has a web style design that no other honda block has got and maks it super strong. they are bad about spinning rod bearing if you are ruff with them. but i seen them take alot of punishment before they go. I got laser-cut custom spec crank and then balanced and blueprinted my block so until i got badass pistons and rods i would have to worry as much. it just varys depending on driver and engine.

 

h23 are plumbed for vtec but with mine i opted to run a external 7/8'' oil line directly to the head so i wouldnt have to mess with block. as far as the redline goes in h23/h22 motors and LSvtec motors of course the blocks cant redline as high as there vtec heads allow them but that can be fixed with rods,pistons, and balanced and blueprint job. then they are capable of turning as many rpms as the rods and pistons are rated for. The payoff is the incrediable tourqe from the motors with the addition of vtec.
