search a little more. there is a page around here somewhere that has pretty detailed instructions.
main points to this swap. Not all of the wires are long enough so you'll have to stretch them to their destinations or reroute OR lengthen.
Also this is the big thing. You will use the dx throttle body. the iacv on the ex manifold is different. If you WANT you can go through the hassle of wiring it up but its not going to make any difference in performance and its alot easier to just use a rubber hose to connect the outlets on the ex iacv as a bypass. you could even make a block off plate if your creative enough. other than that just drain fluids. disconnect everything. unbolt the old manifold. swap over your throttle body. OH OH OH i forgot. when you swap your throttle body, you will need to use the throttle pulley off of the ex tb. its easy to take off. and you need an ex throttle cable. bolt the new setup back up. make adjustments with wires and plug everything back up.
im still having a problem with high idle when i first crank the car and its cold outside but it goes away after warming up. no big deal. ill get around to fixing it later. if you have any questions let me know.
if i left anything out or this made no sense excuse me cause im typing in a hurry before i leave work.
Later,
brian
