Rb20 Maf Repair

Some of you may have seen my RB20 powered RX-7 or my RB20 powered 48 Studebaker, shown elsewhere here. If not, you can see the build details on my website stilettoman.info in the automotive section

I have been plagued with electrical / engine management gremlins in the RX-7, finally bit the bullet and bought a Wiring Specialties harness. That solved many of the problems, but it would still cut out momentarily at random times. I got the analysis software from Concept Z, and it showed that the MAF signal was going away when the engine cut out. I was told that "you cannot repair a MAF, just buy a new one". After consuming some "brain enhancer medication" (bourbon) I decided to find out what this mysterious device looks like on the inside. I started by removing the connector plug, which pulled out fairly easily. The solder connections came off very easily and I noticed that one of the connections left no trace of solder on the copper contact. My immediate reaction was that this was my problem. I cleaned everything, reassembled it and resoldered the connections. The car now runs flawlessly.

I realize this may be a very rare occurrence, but just thought I should pass this on in case any of you Wizards of Oz like to spend your money on medication rather than car parts.

      rb26, build year ? check my math

      By Butters · Posted

      found this on the forum , suggests I am in the range  ----------------------------- From the segmented (potentially incorrect) information I've found that;  Early R32: RB26000XXXX to RB26002XXXX  Mid R32: RB26003XXXX (V-Spec I RB26-03XXXXX - Reference Classic Register) Late R32: RB26004XXXX (V-Spec II RB26-042XXXX - RB26-045XXXX - Reference Classic Register) Early R33: RB26005XXXX Mid R33: RB26006XXXX (as per the engine in this R32 V-Spec II, which is what I'm concerned about from legitimacy perspective) Late R33:  RB26007XXXX Early R34 (2000+):  RB26008XXXX ----------------------

      Now as I understand it the engine numbers are sequential for the rb26.  EG stamped - RB26040100A is a 40,100 engine.    Now they made between 1988 and 1994 43,834 R32 GTR's  In 1994 they made 7,464 r32 gtr's.  So if you have a ~37,000++ number RB26 it's "safe" ish to assume its an 1994 motor and a long nose crank ?    The long nose crank being introduced somewhere in Feb of 1993.

      By morboost · Posted

      what exhaust, intercooler, turbine housing? I don't get this part ngk 7’s spark plugs (tuner refused to tune with 8’s for my car) why is the keyboard operator telling you what parts go in your car comes of as controlling, controls your engine, your tune, your horsepower.
