Mazda 91 Lx to Mazda gtx swap--->new member
Hey guys, glad to be apart of the club protege scene. Seems legit haha
Lets get to bisiness, It all began when i bought my first mazda fimilia car, a 1992 ford escort gt. Fell in love with the car and had plans of turboing it and such. I did my research and learned about all the great interchange parts that mazda famillia has to offer and so my quest began. I Found out about the mazda 323 gtx engines and though it would be grand to put one of those in my escort. The 1.8 bp26 I would cheak craigslist every once in awile for them (never really expected much) but one day i stumbled acrost a 1991 mazda protege lx with a 1.8 bp26 swap (came out of the mazda 323 gtx as you well know) for 1200$ and about a 30min car ride. Went to cheak it out and seemed legit. I cheaked it out and the guy was running it without the turbo. N/a setup with the stock lx injectors with lx stock mass air flow running on the bp26 (gtx) ecu. It ran like a champ to (don't understand why). I asked why the turbo wasn't on it. He said the guy that sold it to him said it was blowing out black soot out the exaust and running real rich when the turbo setup was on. (The good news was the turbo (vj20) setup and injectors were in the trunk) He said just needed a fuel pressure regulator and it would be good to go. Needless to say i bought the Car for 850 and drove it home with plans of swapping it into the Scourt.
To save time, cause get to up for work tomorow at 430am ill shorten this s*#% up.
I decided to keep the engine in the lx because the body/chassis was in alot better shape then my escort gt (and i bought it with an r-title unknowingly) so it wouldn't be worth it.
I bought an intercooler kit and piped it in myself, threw the turbo on it with the gtx blacktop injectors, and the jdm mass air flow that came with it on the car. After some test runs the car was running really really rich (and was blowing black soot like he said) and came to the conclusion it was the mass air flow because when i stuck the stock lx mass air flow it would run lean. The guy who owened it before me bought a 1.6 mazda gtx reman mass air flow instead of the 1.8 mazda gtx mass air flow. *smack head*
So considering i couldn't find a jdm 1.8 323 gtx mass air flow anywhere i decided to get a SAFC-II and control the air/fuel ratio manually. I can't really do much considering i need a a/f ratio gauge. So im waiting on a AEM Eugo in the mail currently then i can get to work (should be here in 2 days)
I am just cureous about what you guys think about using the wrong maf with the right ecu and trying to make it work by using a SAFC. I have the stock lx maf which runs it too lean, and the 1.6 gtx maf that runs it too rich. Which would be better to use (the1.6 is bigger and i would gain some hp because of the bigger diamater.)
Ill post some pics and update tomorow, gtg, chow
