Kpro is essential, attempting to run a stock A2 ECU will create a dog that a bolt-on equipped A3 will walk all day long every day!

I was going to go that route but when all the costs are figured out the complete A2 swap was the same price

I agree Doug. I wish Tim (aka Gearhead Geek) was still around. He moved onto his WRX and hasn't looked back. His head swapped Ep3 hauled balls. I rode in Sam's (ShadowMD) K20a2 Ep3 and then rode in Tim's and although Sam's was definitely faster, Tim's K20a2 head swapped K20a3 was no slouch.

Oh, and for those inquiring.....

K20a2 head with rocker assembly, cams, all pins = $500-$900
or
K24a2 head with rocker assembly, cams, all pins = $200-$500

OEM Honda K20a2/K20a3 head gasket = around $110
ARP head studs = around $150
Misc. = $30-$90
Kpro = $900


So like Doug said, it's not cheap. But if you get the head cheap and/or you already have Kpro, it isn't that horrible. Plus you'll need the K20a2 head anyways, when you upgrade to a K20a2/K24a1 Frankenstein!

I was searching for something and this popped up. What a blast from the past. I can't believe that was about 7 years ago. I had to make a new login because my old username is longer than allowed now. :tehe:
