I heard you can put a mass airflow sensor off of a six cylinder onto a 22re for improved peformance? what year of six cylinder and what vehicle? It wont make it run rich or anything? will it still smog?

Per Jeff Mosk - dunno if this applies to the 22RE:

The 1982 5MGE Supra AFMs are supposed to be plug-and-play with the 22RTE, while the 1983-1985 AFMs from the same motor require the circuit board swap I document on my site. I say "supposed to be plug-and-play" because I haven't done this swap myself and therefore haven't verified the results, but I believe this has been pretty well established by others.

I heard you could take a MAF out of a six cylinder celica (a 1980 something model) and it was a bolt in upgrade, they looked almost identical but the six cylinder MAF flowed more for a couple extra ponies

It only needs to flow more if it is a restriction. On a stock 22RE, the AFM is not a restriction. On a modified 22RTE, the AFM can be a restriction.

Otherwise, as Darin quoted from my site, the 1982 Supra 5MGE AFM is plug and play for 1986-1988 22RTE motors, but will obviously need some tuning to work. It has also been used with 22REs from similar years. The 1983-1985 5MGE AFM can also be used, but the output signal is the inverse of the 22RE/RTE signal, so unless you swap over the 22RE/RTE resistor board, it will put out the low signal when it should put out the high signal, and vice versa. This means at wide open throttle, it will tell the ECU the motor is idling, and at idle, it will tell the motor to send enough gas for wide open throttle.

Clear?

Bottom line: unless you are making more than 160 rwhp, you don't need this mod.

the *other* thing to mention is that toyota tended to match the size of the AFM to the size of the TB.

Changing the AFM without changing the TB size, you're still pushing air through a small hole. It's best to change both.

You can get a relatively bolt-on TB from a similar year Celica, but it doesn't have an IAC, requires some porting of the upper plenum, and modification of the throttle linkage.

Consider going to a late model upper plenum first, then if you have the HP to warrant it, consider the AFM/TB mod. The AFM.

Sorry to hijack your thread but I didn't want to start a whole new thread on the same subject. I was wondering if anyone can find a link on how to relocate the afm to the battery side? I have been searcing everywhere and I can't find any info on it.

Thanks,
Brian
