There are two models of engine in this year one is a 1.1 liter
and the other is a 1.3 liter both rotary engine
you can identify them like this

the 1.1L engine is a 4 brl carbureted engine
the 1.3L engine is fuel injection

yours is a 12a = 1.1 liter rotary carbureted engine
the 1.3l is a 13b engine code fuel injected

Have a great day !!!!

MY 1984 GS CARB RUNS GOOD, STARTS GOOD WON'T IDLE BELOW 1500 RPMS, CLEANED CARB, ALL JETS CLEANED, JUST GOT IT AND WONDER IF SOMETHING NOT SET OR CONTROL HOSES ON WRONG, I HAD A 1984 NEW AND A 1985 YEARS...


Replace your fuel filter first, cheap and easy to rule out, probably needs it anyways. Could also be a massive vacuum leak. On that year's carb there are 2 adjustments... Here's a page on idle tuning: http://sterlingmetalworks.com/tuning_the_nikki.htm

I would like to identify a block # of 1m0525 5vp.


from what i find , the format of the number is incorrect. Engine ID Code Example: V0107CLJ i can find meanings of the "m0525" but nothing on the first 1. and the suffix code is 3 letters. so from what i worked out, the "m" would be from the mexico plant. and the "0525" would be the engine build date, may 25th, no year stamp. the "5vp" is what's got me. there's only 4 suffix codes i found that start with numbers and none are 5vp. the closest i found on just the "vp" without the "5" would be a "vr" listed as a 350 1969 with 4 barrel carb out of a c-20 or c-30. the closest i could find for "5vp" would be "suf" and there were 2. both listed as 305's 1984. one out of a monte carlo and one out of a firebird.
