#282638 Nice! You should get some K20A2 cams for your A3 and you'll add more power. I saw a dyno sheet once with that and it was an awesome gain.

The car looks good though!

#282674 From some one who has a k20a3, sell it and get an a2. if you go with any k you would need kpro, but if you get the a3 ecu kpro'd your stuck with the a3. it will not work with the a2 or a/z/z3. so i would get the better k before you get balls deep into a a3. a b16 makes the same power, or even a b20. both easier to swap and both easier to make power with.


nice car btw :thumb:

#282710 thanks everyone... i didnt buy the a3 i just have it for some reason...so i figured i would put it to use. but i was thinking of just doing the simple b16 route. the b16 is probably lighter also correct?

#282712 yes i believe so. The a3 can make power with boost but converting a eg's wiring over just isnt worth it.
