Looking good man! Looks like a ton of work too. Good luck. I want to add a JRSC at some point next year also.
Where did you get your a3 JRSC? Street or Race?

Re: ep3 k20a2 jrsc build
That's an A/F ratio code. You need to reset your Kpro injector setting to 650cc (please don't tell me you're using the Powercard).
What header are you using? I'd also ditch the Greddy exhaust for something better, or at least cut out the bottlenecks and weld in 2.5" piping.
Also - that was really f*cking stupid to swap the oil/water pumps like that. I'm pretty sure the a2 motors have different flow rates for the pumps, and you've lost the beneficial oil cooler (it's not that great anyway, but it's better than not having one - especially with hot supercharger oil flowing through your engine).

Re: ep3 k20a2 jrsc build
^ the a2 oil/water pump wont work on the a3jrsc, the jrsc will hit the manifold. an it isnt just only me that swap the oil/water pump. i would be really happy if i could use the a2 oil/water pump to keep my motor colder, but later on the future ima get me a mini radiator n stuff to connect to the charger to keep it twice as cold.

Re: ep3 k20a2 jrsc build
^ I read up on that as well when I was shopping around for one. The side mounted design of A3 jrsc's like that. If you have dc5 spec jrsc, it's a different story.
Oh Nemo, I just found a mini version of Nemo in my daughter's toy box, lol...
One more thing, if you ever sell your wheels, LMK!!!!!!!!!
