and can i adjust the timing on my dizzy if so what way should i rotate it???? the cam is the AU equavilent of the 977b

au's are coil pack... no dizzy..
idk if you can rotate the crack angle sensor for the same affect though?? (someone correct me?)

get a J3 chip and get it tuned properly, you will pick up a fair bit of power all the way through the rev range and better economy

my au doesnt have a crank angle sensor in the aux shaft. also if it is there dont turn it....it helps the injectors know when to fire where the dizzy doesnt...screws up lots

going by your signature its an xh so you can advance the ignition timing a few degrees.
it would need be rotated anti clockwise.. but you really need to put the ecu into self test mode to adjust the timing with the aid of a timing light.. |

also hybrids are just an au head on el bottom....hence hybrid

ah fair enough, i stand corrected. 6/98 is very close to the 1st au.
shame the last au's didnt come out with dohc...then mine would  anyway time to get back on topic thought about a port and polish on the head?

thanks for the replies and yes it is a hybrid engine
i have a j3 from TI on its way i got some minor head work when the cam was installed as a result of a blown head gasket and wrapped head ports matched and polished, shaved i guess the next step in modifying is bottom end or forced induction

If you're going to turbo it dont convert it to a BBM.

no worries im not going through with the conversion not sure how to wire things up as soon as i see wires i freak out hha

whats the reason log manifolds are better suited for boost?

The BBM has a butterfly which opens at 3800rpm, which can restrict airflow when the car is turbod. It is also easier to plum with the log manifold.
