ruparts Posted June 25, 2009 Share Posted June 25, 2009 hi, the car is a 87 sedan with ea82t /5-spd, heads are not good, so i was wondering if putting a N/A mpfi in where a 82t was supposed to be would work ok? i know the computer is some different , and other parts like intake plumbing , exhaust. would the maf sensor be ok, anyone tried this ? i have all the parts needed except heads for a mpfi engine. any "good" mpfi heads for sale? just looking for a easier fix for this one. Thanks, jim Link to comment Share on other sites More sharing options...
Gloyale Posted June 25, 2009 Share Posted June 25, 2009 I have this setup in my 89 GL turbo wagon. All you need really is a set of N/A pistons to put in the block, an N/A y-pipe with an O2 bung, and to work out an intake from MAF to the throttle body. Might be able to adapt the SPFI intake tube or find a setup on an NA 4 cyl XT. The turbo ECU seems to be able to run the engine just fine, if perhaps not ideal. Oh yeah, and a good set of heads. You could look into having you'res welded. Don't worry about the cracks between the vavles, just get the ones in the exhaust port. Link to comment Share on other sites More sharing options...
ruparts Posted July 4, 2009 Author Share Posted July 4, 2009 hi, thank you for the help, i now have a enginebut a couple of little questions. 1, what did you do to close off the water tube from the thermostat housing that goes back to the turbo? 2, did you modify a spfi intake tube or would it be easier to find a mpfi intake tube setup ? just a few vacuum / pressure hoses to sort out and i think everything else is ok.

Thanks again for your help I used an NA MPFI intake off a 88 XT, so I had no water line to plug, but it could easily just be capped off. I used an MPFI intake boot too, but you could use an SPFI one with the rubber sleeve that joined the aluminum pipe to the Throttle body left on the Throttle body as a spacer (SPFI throttle body is larger Diameter, so you need the spacer to make the boot fit) MAF works fine, but please, put High comp pistons in it or you will have NO power.

idosubaru Posted July 9, 2009 Share Posted July 9, 2009 other than the compression issue, another annoying thing is all the proper vacuum tubes. getting all the plumbing right is annoying as the hoses can be different from motor to motor/turbo-to-non turbo/and auto to manual.
