Thanks for the info. At this point, I'm just going to get the '95 engine. I simply want to get the car onto the road for him with the minimal amount of fuss.

I'm not an expert on this, but I'll take a stab at it: Swapping the ECU is a pain, you'll want to keep the 97 one. The 97 ECU doesn't control the VICS flaps in the intake manifold, so you'd either have to leave them fixed in one position or find some kind of RPM-based switch to control them. You might have to do some wire splicing to get the various sensors hooked up -- not sure if all the connectors are the same or not. The 99 uses a returnless fuel system, and the fuel rails don't interchange, so you'd either need to find a way to put the 97 FPR onto the 99 rail (not sure if it fits in place of the 99's pulse damper or not), or go with an aftermarket rail. You'll want a 97 alternator, since the 99 one is controlled by the ECU and the 97 ECU doesn't do that. > Another data point is that I'll need to put a header onto it.

I was thinking a stock one from FM salvage, or > maybe a cheap one off of fleabay, I don't think the 99 header will bolt up to the 97 exhaust (at least, all the aftermarket companies sell different exhausts for the two cars, and presumably they wouldn't if they didn't have to). A 97 header would probably work, although you might need to be creative with the EGR pipe. You might also want to check the smog laws in your state regarding swapping motors between cars. Neither of these swaps would be legal in California (although I doubt anyone would ever notice), dunno the laws in other states. --Ian _______________________________________________ Miatapower mailing list [email protected] http://list.miatapower.net/cgi-bin/mailman/listinfo/miatapower
