It sounds like you have it all covered, the "PAIR" system will have to be bypassed.

The PAIR system has to do with the airflow delivery to the intake manifold and was set up on the Type I's to help emissions, kind of like an EGR valve. There is a hose that comes out from the firewall the connects to the back of the Type I manifold. When I got my swap done back in 2006, the shop reused my Type I manifold (without my permission) so they would have a place to reconnect the hose. The Type II manifold has better flow characteristics than the Type I so I wouldn't suggest doing this. All you have to do is plug the hose that connected to the back of the old manifold, and you can use the Type II one with no problems. Hope this helps.

I just saw this, here you go:

“1. Removing the PAIR system. The Type 1 uses an air injection setup that the Type 2 doesn't use. On the Type 1 there is a pipe from the PAIR valve to the driver's side exhaust manifold. As long as your Type 2 comes with the exhaust. manifolds you will eliminate this pipe easily. If you had to reuse your Type 1 exhaust. manifolds for some reason then you would need to block off the hole for the pair pipe. You also need to cap off the vacuum line that controls the PAIR valve since it is no longer used.

In addition, you will need to swap over your existing USDM engine wiring harness, the main connectors on the JDM harness are on the wrong side for our purposes. Also you will want to swap over your passenger side valve cover. The USDM valve cover has a temperature sensor on the back that the JDM motor lacks. Simply swap the valve covers and the problem is solved.

2. Yes. The issue has to do with the layout of their cars, being right hand drive. The ecu and wiring is on the opposite side, regardless of Type 1 or 2. Swapping the harness and valve cover takes care of it so it's not really a big deal.

9. Plug off the #7 hose that used to plug into the Pair valve. for diagrams go to DV8's website. Also, swap the passenger side valve cover.

Make sure if you need to order parts for you motor that u order them for a 94-95 GS sedan or 93-95 coupe. If your mechanic gives you some b.s. about not being able to use the Type II manifold, slap him, seriously, and slap him hard, you do not need to remove ANYTHING in order for the swap to work other than the pass valve cover and completely remove the Type I pair system, also, have him use the Type I crank pulley, it is lighter than the Type II. Dont let him b.s you about emissions, my JDM Type II with US Type I ecu passed sniffer here in WI and I can scan a copy of my test if he needs confirmation. Hope this helps, if you have anymore questions feel free to ask.

I hope this helps.

Tranny and ECU

Alright guys, It's been a while since anyone has posted on this topic. But, does anyone know a good source for the TypeII ECU? Never have understood why they don't include the ECU with the motor. Also, I'm assuming my 5spd tranny will bolt right up?
