AKIRA Posted January 6, 2004 Share Posted January 6, 2004 how difficult is it to swap an MPFI engine into a SPFI loyale auto? what do you have to switch, ecu, (engine Of course) what else? Link to comment Share on other sites More sharing options...
Scrub2k Posted January 6, 2004 Share Posted January 6, 2004 I Think that you can use the SPFI ecu, everything else should just be a direct swap. Link to comment Share on other sites More sharing options...
archemitis Posted January 6, 2004 Share Posted January 6, 2004 spfi ecu wont work you would have to swap wiring motor and computer. fun stuff, good luck. Link to comment Share on other sites More sharing options...
JonOfScio Posted January 6, 2004 Share Posted January 6, 2004 engine manfiold ECU wiring possibly fuel pump, if the GPH/PSI is different between the types of fuel systems... I don't know and I'm too lazy to look it up. As far as I know, the MPFI EA82 has the injectors in the manifold... so you wouldn't actually need to tear the engine apart or even take it out. Unless you wanted to rebuild it. And the SPFI block has higher compression to it, so to MPFI an SPFI block isn't at all bad. Later on, you could swap the MPFI ECU for a turbo ECU and add the turbo/related parts (resulting in a 9.5:1 CR EA82 turbo engine) Which has been done. (actually, was a turbo engine with switched pistons. same idea) Link to comment Share on other sites More sharing options...
archemitis Posted January 6, 2004 Share Posted January 6, 2004 except there is no diff between the na and turbo computers, just a wire you ground or power i for get Link to comment Share on other sites More sharing options...

AKIRA Posted January 7, 2004 Author Share Posted January 7, 2004 sorry, You have the wrong Idea, this isn't a performance thing for the Loyale, I should have explained that, I think I can get a MPFI engine for about $100 and I would like to put it in my brat, If it would also work in the Loyale my dad would be more likely to get it for me, as it would be awhile until we could put it in, so if the loyale dies we could use that engine in it, whew, biggest run-on sentence ever!

archemitis Posted January 7, 2004 Share Posted January 7, 2004 i think it would be just as much work to make it work in the loyale as the brat. if the loyale dies, throw that brat motor in there, and use the mpfi in the brat. Link to comment Share on other sites More sharing options...
MorganM Posted January 7, 2004 Share Posted January 7, 2004 If the MPFI is a good deal I see why that would motivate your desicion but honestly the MPFI is overly complex for little to no gain. Would be much easier swaping and working on an SPFI or a carbed engine IMHO. You can really strip down the SPFI and carbed models to just bare minimal function and get it working in no time. Just my 2 cents. Seeing a BRAT with an MPFI engine would be neat tho Link to comment Share on other sites More sharing options...
CIS Subaru Posted January 9, 2004 Share Posted January 9, 2004 TURBO Brats have MPFI engines, so just find a pic of one if you want to see a MPFI Brat. Link to comment Share on other sites More sharing options...
AKIRA Posted January 9, 2004 Author Share Posted January 9, 2004 okay, thanks. I think I'll still get the MPFI, but just for the Brat. -AK. Link to comment Share on other sites More sharing options...
