I am new to this site so hi to all 200sx club members
Ive redone the hole engin with a set of ARIAS pistons but the ignition timing is 25 degrees before TDC can not get it to 15 degrees before TDC.
and my crank angel sensor is turned fully clockwise what can i do to fix this probem thanks.

I have seen this before on CA 18's
1st check that your cam timing is spot on it is very easy to be one tooth out on the crank. This means each cam is half a tooth out and it looks ok to the casual inspection.

Agreed check the cam timing its happened to me before.
do you still have the keyway to line up the CAS or has it broken off?
Because you can put it a tooth out if so.

Very bad Blow-by will do that
Check you PCV system and do a Compression Test.

What I meant was no, not unless you are 100% certain its in the motor.
