i have been told that i can make a prelude (a 90 2.1 Si) into a vtec motor by changing the head to a vtec head (like a 93 or later) and change the ecu. is that all? what about the crank, the intake, or anything else? is it really that simple? or is it more complex? what about the tranny? will it be able to handle the change in power?

Tom is still working it out, I think. E-mail him.

yes you can.... but it requires modification of the quench areas due to different bores.

 

It is pretty complicated, yet well worth it. When I get a new engine I might do it too.

 

thank you clockworks - the site had exactly what i was looking for for information - do you, or anyone else know of any sites that i can go to for suspension and body kits for the 85 prelude and the 89 prelude generations?

This site is made by antonio, I have his car now, but you will find it very helpful. It is a later model prelude, but they are very simular.

I also recommend http://www.hondaprelude.com/ search though your year prelude, and get ideas, it is very helpful.
