coupe Posted January 19, 2011 Share Posted January 19, 2011 Hi Gang Im in the middle of stripping and fixing a turbo ea 82 (1988 spider manifold) that has blown head gaskets. If i wanted to replace the motor with a mpfi 82 (1989 normal manifold). is it achievable. I assume i have to replace the exhaust, computer plumbing to airbox. Is there anything else. Can i use the spider manifold. Any information would be appreciated. Cheers Pete Link to comment Share on other sites More sharing options...
skishop69 Posted January 19, 2011 Share Posted January 19, 2011 Correct, you'll need the donor exhaust 'Y' pipe, the ECM and harness for it, airbox/ductwork and I believe you can use the spider intake. Something with the TPS (throttle position sensor) has to be rewired IIRC from what I've seen here. Something to do with the throttle stop portion of the sensor that tells the car when it's at idle.

MilesFox Posted January 19, 2011 Share Posted January 19, 2011 you could build your turbo heads on an spfi block, and find the right intake boot and be done. The ecu should work the same. there would be a pinout on the ecu harness that grounds out to identify the ecu for turbo or not. Link to comment Share on other sites More sharing options...

Cheers Pete hi, i switched a turbo engine to a mpfi engine ,I am still using the original intake and wiring and ecm that was with the turbo car. so i think you only need change the exhaust and a few things like vac hoses , air intake , and block off the water pipe from turbo on the intake. i have been driving this car as a DD for 2 yrs and the original ecm , afm, inj's, and stuff works just fine.

coupe Posted January 20, 2011 Author Share Posted January 20, 2011 well i stripped the heads off the turbo. First thing i find is the previous owner has tried to put chemi weld or some type of sealant through the motor before he sold it to me, most of the cooling system is nearly completely blocked. this was a overheat waiting to happen. The bores are screwed, they are pitted and rusted. The motor got hot enough to actually miss shape the cam belt boxes they are all slightly melted. So its put in the mpfi motor and out with the turbo. I will have to see if the spider manifold will match up or its a standard mpfi for me lol.
