ey I was wondering if anyone here has swapped in a 3sgte from a usdm turbo here, I'm sure someone has here. I was wondering if the wiring harness needs to be extended with a usdm 3s, or if any other modifications are necessary.

o, btw, this isn't Jim, this is his friend Mike

thanks guys

Yes it does its the same as the JDM 3stge swap, just less HP.

not only less hp but it would be impossible to find one with less then 80,000 miles on it unlike the jdm ones that come with around 40,000 or less.

My JDM engine had 45,000. Main reason ppl go JDM its actually harder to find a USDM engine.

you dont need to extend the harness. even with a jdm engine.

when i took my 5s out, i cut a hole in my firewall, right behind where the ecu is. that way the cables have a direct path to the ecu. i think this is better then extending, because u dont have to worry as much about those wires coming loose and causing you problems.

^ Agreed.

hmm some intersting posts her but firstly you can get the jdm ecu and hook it up to the usdm 3sgte to acheive a 25 hp gain you only need to run higher octane fuel. secondly i never knew the usdm second gen 3sgte was set up for a right hand drive....
