How much HP will gain to tune k20a3 with out swap engine? thx

Ummm, what???

I think he's asking what is the max HP you can get from tuning a K20A3 without swapping it out for something else. I could be wrong though. :confused:

that is the most terribly put question i have ever seen!

He's Filipino, guys. I'm sure his English is better than my whatever-the-hell-they-speak-over-there. Spanish maybe? Mi espanol no es muy bueno.

Anyway, I don't know shit about K engines.

yeah he should post this is the rsx forum

yeah he should post this is the rsx forum

well, my engine is originally K20a3 from factory in a civic 7gen body!!

K20a3 - 160 hp -Civic SI/RSX
K20a2- 200 hp - RSX Type S
K20a - 220 hp - JDM RSX Type S

All which come with DOHC Vtec or I-Vtec
Capable of handling all the extras you want to throw at them. There is no need to swap a K series motor unless your going to buy another K series motor better then you K20a3, which would mean getting the JDM Type S motor which is selling for 5k right now. You have a great motor just work at it. No need to check the RSX sites, just check around for Civic SI's and what horse power gains they are getting and what mods you would have to do to achieve that. Also do some investigating of your own before you post, and after that go to www.7thgencivic.com (http://www.7thgencivic.com) to do some searching.
