Re: ca18det rev limitor
With the amount of info available I'm going to guess boost cut.

Re: ca18det rev limitor
1) Set your timing properly before you nuke your rebuilt motor.
2) Do you have the stock T25? running stock boost? I'm guessing not.
Boost cut: When your MAF maxes out the ECU cuts fuel to prevent the over-boost as your fuel system cannot support that much air into the motor.
PS: You say it's the rev limiter, but it could also be that your cam timing is out one tooth and the motor simply cannot increase rpm - this is a common mistake when working on CA's.

Re: ca18det rev limitor
Kwl will do but i got a feeling im a tooth out on my timing. When i set the timing with a timing light it must match up with the second ridge right?

Re: ca18det rev limitor
I checked and mine is way out and adjusting the cas still doesn't bring it to the second mark it must be a tooth out
