Can it be done? Can anyone help me with it?
Just thinking about some possibilities for my 91 SR/SE 4WS.

 

Yes, it can be done, however it will not bolt right on. You can put an H22 head on but you will need to modify it so it can work. I don't recommend it though because the B21 has a relatively weak bottom end compared to most Honda motors. I was considering puttong a VTEC head on my car (90 Si), but it wouldn't make sense due to worn piston rings. My advice if you want serious performance...... H22

 

actually, a better choice would be a B20A. it can be done, it has been done.
B20A bottom is pretty good, even for FI. B16 head would be the best choice, but you would need to do modifying to make it fit.

 

I've heard of enough people attempting to do it, but I have never heard of a completed, running, and reliable one yet. I think it really isn't worth the time and money to do it. BUT, if you are still interested, Tom from http://www.Ludespeed.com was and may still be making kits and doing the headwork to do that.

Edit: Nevermind, it looks like Tom isn't even doing turbo kits anymore either. You could email him to get his opinion on it though.

 

Still check out Tom's site because he still has all the articles on there. I thought of doing the same thing too, but an h22 just sounds like more fun! If you want some power, go to http://www.hmotorsonline.com to pick up a motor and then check out http://www.placeracing.com to get the parts to drop it in. For about $3800 you can buy almost all you need. I know we are not all made of money, so thats why I am waiting for a long time to get one! Let me know what you decide on and what works out for you.
