ca18det rev limiter problem - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

alright so i just finished throwing in this ca18det swap in my s14 . i upgraded the stock turbo to a gt28 turbo , i am noticing when i drive the car , 1-3 gears are fine when i get to 4th gear and hit about 3100 rpm with the throttle fully open nothing happen after that point until i go under the 3100 rpm mark. its usually right before the boost kicks in in those high gears.

and when i get to 5th gear i can not exceede about 2500 rpm .

i am not sure if this would link to a maf problem. or a boost problem .

but i can pretty much red line the car in the first 3 gears and boost no problem.

some input would be nice ! thanks ZILVIA PEEPS.

unplug your speedo.. might fix it if its speed cut

get injectors (like 550cc/min from an rb), an SR20DET or Z32 TT maf, a new fuel pump, and someone to map that before it dies.

I hope you are not using that with the oem FMIC too ...
