so i just bought a 92 Lude' with an f22a. It's a great fun little car, but i want to get more power out of it. Right now i just put on a Greddy High Flow exhaust and an AEM intake. Do you know of any other ways to get more horsepower out of it without swapping it to h series? thanks

 

Well, you don't necessarily need to go all the way to h series, but you can source just an h22 head and bolt it on the f22 block making it a "g22".
Bolt pattern is exactly the same and you can find DIY instructions for the swap in the Prelude FAQ.
