what types of up grades are there for k20a3 and is it worth upgrading and what horse power can i achieve with the k20a3

 

It's kind of the bastard engine. Turbokit is really your only feasible option.

 

Well I have a 04 SIR with the K20A3 and I'm at about 178 hp and 150 ft/lbs With all the bolt ons and tuning. (Greddy E-manage, Injen CAI, Alpha werks header, Evo 2 exhaust, Heat shield, Hyper Voltage and grounds) I bet there is more power in it to get a strong 200 to the wheels with some more tuning. I have beat a RSX type S and some Mazda 3s and Tyburons. If you want more than that you could get more out of cams (if you can find them) but if you want the easyer way and could end up being about the same amount of money with more power, go with the turbo and tuning.

 

go with the turbo and the k-pro it will work wonders for you
