Hey John

Differences between us and jspec:

Us: 165 hp 165 tq, 9:1 comp - kl01, kl07 ecu and kl02 VAF
Jspec: 200hp 165hp , 10:1 comp - chipped ecu or kl31/kl36 ecu needed

Depending on what jspec motor you get (curve neck) it will have the same cams as the us spec motor.

I get my motors from jdm source.. U should be able to get a curve neck for 8-900 shipped taxes in to a loading dock in vancouver.

Or you can get a DE from pick n pull and drop that in with the stock DE ecu and VAF and be good to go

I got the ecu chipped by probinator @ "probegtze@hotmail.com" email him for more info, hes slow to reply. I would recommend that route if you have some time. If not try to hunt down a KL31/KL36 ecu from probetalk or mx6.com. DO not buy a ecu from JDM source as they may give you a wonky one or overcharge. They are going for less then 140 now. The difference between the two ecu's is negligible, one is a Auto ecu and one is a MTX ecu apparently. Either way, they work the same. They both come from the Jap MX6 paired with the straight neck motor.

Probinator will be able to chip our ECU so that your VRIS points match (if you go with the plug and play curve neck). KL31 or 36 will have the incorrect points but it will still haul a--.
