F22 compression increase

[evac]

I've got a 91 lx with I/H/E, aem pullies and a holed-out cat. Is it worth it for me to increase compression? What's the cheapest way to do this?

You shouldnt have hollowed out your cat. It causes Flow stagnation and decreases low end power and overall performance. It act likes a hollow box and wont help you out any. I would chunk that thing. It be better to get a straight pipe or go on ebay and get a 50 dollar high flow cat.

If you want to increase your compression I believe you can do it with head gaskets. I know they make some that can lower so theres a starting point. I think your money would be better spent doing something else though. Myabe a fpr and fpr gauge would be nice. Just some food for thought.

mill the head...30 would be good.

edit: thinner head gasket..

[dru_gsr]

but how much of a gain do you really notice with that? i think you have to do other mods to really notice the true gains of the mill.

nope...not to raise compression?!??? you'd want a THINNER gasket to raise compression. think about it. closing the space between the piston and the chamber in the head would increase compression.

oops meant thinner.

I didn't know they made thinner gaskets. : Know where I can find one?

i've never seen one for the accord f-series motor...spoon and mugen make them for b series and h22 and f20b tho :

i had a friend just get a cheapo head gasket from autozone, then take it apart so it's just 2 layers instead of the 4 or 5 layers. then sprayed it w/ copper. ghetto rigged....lasted him a month

rule of thumb

for every 0.1:1 compression you raise.. 1% overall power increase.
