I got my setup from japandomesticmotor.com, dealt with Wais. I got a full engine swap package, only thing I had to buy outside of the engine purchase was the avcs wiring harness. I paid $3500 shipped for my 2003 ver 8 engine including a down pipe and ecu. The intercooler was missing the recirculation valve, he sent one out as soon as informed him of it been missing, no hassle no run around. I could have purchased a ver 8 spec c from him for $3900 shipped.
I definitely recommend them, they also have a 60 day return policy vs the 30 days all the other JDM vendors seem to have.
I installed a gates racing timing belt kit, oem thermostat, NGK iridium BKR7EIX #2667, oem oil filter and semi synthetic oil for initial start up and later changed to rotella t6. I also got a Tomei down pipe and a borla hush catback. It was very simple to just add a couple of inches to the intermediate pipe to get the U.S market catback to work with the JDM length down pipe.
Check out oakos.com for the gates timing belt kit, they had the best price.
