I've been looking at engine swaps for the last two weeks and was wondering how much more work is envoled in puttinga H23 vtech into my 91 lx thanjust getting an h22. Are there any real advantages one enginehas over the other? Will the H23 justboltinlike the H22or will i need to make modifications?A little off topic, butI wasalso lookingaboutan F22Z2. CanI even get a F22Z2 in the US and is itreally that much betterthanmyF22A1?

 

envoled should be involved. Sorry, it's late here.

 

Never heard of the F22z2.

H23vtec is the same swap as the H22, just a larger stroke.

 

Hi there

The F22Z2 is the Euro/UK 2.2 VTEC lump - Have it in my Accord here in the UK, Its an ok engine, tunable to about 315/320 bhp with a Treadstone Turbo kit and uprated internals @ 15 psi comes with 147 bhp standard. (I have not done it - a friend has though). I was thinking about going that route but my friend has suggested trying to locate/import an F22B1 lump as its going to be easier to source parts when going for the Turbo upgrade.

Hope that helps a bit

 

If you're going a turbo route you'll want the F22B2 (non-VTEC). Having VTEC kick in is going to screw up your turbo tune.

 

Thanks for the informations guys. SinceI seriously doubtI can get a F22Z2 imported for less then it would cost to get a h22 or h23 I guessthat's the end of that. I'd reallylike totry and get a h23 v-tec because it seems to be rarer then most swaps. I want to know more about the swap beforeI've fully decided though.Can anyone tell me what all will have to be replaced to make theh23 v-tecswap possible? Also I read somewhere that all the h23 v-tecs have electric power steering because they're all jdm, so can it be modified to use hydraulic power steering? Can my car be modifiedto use the electric power steering if the engine can't be?

 

I highly doubt you'd even want to try and make electric power steering work on your car.

If you plan on using the H23vtec, most if not all of the PS components from your F22 should bolt right onto the H23 block.

 

If electric power steering was the only wayit would workI was just going to leave it off the car.

 

Just a few more questions. I plan onkeeping my f22 tranny unlessI can find a h23 v-tecthat is already been swapped from the stock AT to a MT. SoI needto know ifI canuse the parts off my f22 tomount my 5spd trannyorwill Ineed to get other parts to get it to fit. Also what all willI need todo theswap right the first time? Axles, tranny mount,or any other parts that will have to be changed during the swap. I know I'll need a new ecu sodoes anyone know what ecuI should use?

 

Your tranny will bolt up fine, so will the mounts, and axles. Since you have a 91, convert the motor to OBD1 and use a P28 ecu with a tuning program of your choice.
