Ok, did a search but can't find anything. I just sold one of my friends a base 2000 Prelude. While deciding what direction to take it in I mentioned the Type S to him. I realize that this is (correct me if I'm wrong) mainly different cams, pistons, rods, header. Is that right? Does anyone know what kind of gains to expect? Has anyone tried out just the cams or header?

I'm trying to figure out if it's worth it to crack the motor open for 10-20 hp difference. Also, does anyone know the compression ratio difference?

Any help would be greatly appreciated.

Thanks!

 

I too, want to know about the type s cams,rods and pistons. Any data would help.

 

You should be able to get 10-20 hp out of a US spec engine with just bolt-ons (Cold Air Intake, Header, Exhaust, Pullies, V-AFC). So IMHO, it's not worth it to open up the motor if your goal is to equal the output of the TypeS...

I gained 12hp at the wheels with just a header and cat-back exhaust...

Great comparison of the differences between the H22 and the Spec S... enjoy.

 

interesting

 

Are ya sure you got a full 12 hp jus from that??? Did you dyno it or what

 

Yeah. Mugen catback and Mugen header gave me 173.5whp vs 162.8whp stock. Peak gain was over 12whp and over 8lbft.. I did a pretty detailed post on my dyno plots and comparison here last fall. Try a search for the post...

If your friend has a base, he would be better served to try to buy a JDM S-spec engine/tranny. 220PS (same as type S) w/ the added bonus of a factory LSD. No ATTS unit to worry about.
