10v rev limiter

spink · 22-06-12, 08:03 PM

anyone know where they are on a b reg 2 ltr ?i always thought it was the rotor arm that did this but on this engine it is a solid rotor with no mechanism.runs and drives 100 percent but rev limiter is too low

Out of interest what rpm are you being cut at?

spink · 22-06-12, 08:14 PM

about 4k maybe less,quite annoying (btw B reg is 1984 to 1985 for any overseas viewers)

According to the B3 haynes manual it is so until 1989. when it changed to KE-jetronic with hella ICU.

Sounds like the car has a 4 cylinder fuel pump relay fitted

My very first KV engined CQ had a limiter that tended to 'slip' Redline was 6,400 but then slipped down to 4k so I had it reset and quite quickly it dropped down to 4k again so I had the mechanic remove the limiter on the promise that I didn't blow the engine!
