2003 reg s3 will a large port head make much difference and how much of a job is it put change over to one of these

We need a bit more info on your engine and whats been done to it

Basically yeh, more flow, more timing advance, more power, generally.

would a port and polished head set up for a APY engine s3 fit too a BAM s3

 

[Andrew@A.L.D]

The APY never came as a large port APY was small port as well as BAM

AEB and AGU are the main large port heads to look out for.

Do a search and you will find all the info needed about the swaps.

With your spec your best fitting a hybrid, manifold, 440/550cc injectors and then you'll be flying

Yes but a ported small port will not flow as much as a standard large port

well its just that i have just seen a APY head that has been ported and polished so would this not mean it is a large port now?

Instead of starting numerous threads asking questions that are all related to your engine build it might have been better to stick it all in one?? retains a little context then and neither you or people replying will need to repeat themselves

APY is small port and even a ported small port won't flow the same as a large port... porting a small port does not make it a large port... ever
