Want this question answered?
on top of the upper intake there is a screw. it can be used to adjust idle speed.
13b or 13b turbo
engine core - about 90kg's.
the American 13B-S5 has 200hp the JDM 13B-S5 (which is what I have) has 220
My 91 rx7 idles at 1000-1200, which i believe is the norm.
Depends, which engine is in the 85, 13b or 12a?
140 nm
Gsl= 12A , Gsl-se 13B.
the idle up and down is due to the idle air control . coolant runs through it telling the engine what the air temp is and adjust intake air according to coolant temp .. or you might just need to make sure there is enough coolant in the system . as for smoke there could be a stuck open oil metering valve or injector or a bad oil seal . master Mazda tech .
Mazda's 13B for the 1986-88 RX-7 made 146hp without a turbo and 185hp with a turbo.
Turbos gone bro :S
on the 13b engine it should be behind the waterpump, just below the thermostat.
