You can find some good posts here about it, using the search, that list the HP increase of the different kinds. I believe you will gain about 5-7HP on that engine.

I agree, with headers and full exhaust you may get 5-7whp, 8-10HP crank if you are lucky. With just headers you may make a few HP.

I'd expect to make 120-122KW on your next dyno but who knows, could be more, be surprised if it's less.

You in Australia, I'm just wondering because of the Eunos name and you referring to KW instead of HP?

I just bought headers off ebay, was a b---- to fit but worked out nicely. Going to get a dyno and stuff soon. Still need to get the exhaust modified to fit though. No muffler = loud as hell.
