a6 cam in a4

[greenmachine9]

i have searched but failed...lol my question is, what all is needed to do this and will i need a tune-able ECU or can i retain my pt6? thanks for the input

I believe all you would need is the cam.

awesome..i have the cam and the a6 intake mani is installed already
thanks

Well if you have the A6 IM you should get the A6 ECU so the IM can function properly.

He said he has a PT6 already, unless that was a typo. Adding the A6 cam will only make things work closer to the right way.

An F22A6 is identical to the F22A1 and F22A4, aside from the cam, intake manifold, ECU, windage tray, exhaust manifold, and valve springs. In other words, the castings are identical, as are the internals.

My bad, I assumed from the way he worded his first post that he had the stock A4 ecu.

from what i heard the block from an a1 is the same but diff (from the a6) only because the a6 comes stock with an oiler cooler. i believe thats correct?

i do have the a6 ECU...already installed with the IM planning on doing the cam this weekend

Yep, the cam will just complete your setup to be what the PT6 was designed for OEM.

On a side note:
When I ran the H23 IM & PT6 ecu BEFORE putting in the a6 cam, I got exceptional fuel mileage. Better than all original LX with P03 & better than after installing the a6 cam.

I've heard mixed reviews of the PT6 on an F22A1. Maybe the manifold is what does it... I think the few people I've talked to that had bad gas mileage the PT6 were running it without the intake manifold (which really doesn't do anything worthwhile for them).

i am getting an average of 30 miles per gallon with the setup i have now...a4 motor a6 IM and pt6 ecu...with spoon cat, 2.5 exhaust and intake

Has anyone ran an a6 motor with a pt3 & a1/a4 intake manifold?

[deevergote]

Basically an A1 with an A6 cam...


There would be no reason to downgrade the A6, but an A1 with an A6 cam would still probably see a minor gain...

Really, you're looking at MAYBE $150 to $200 for a full A6 conversion... it's really not a big deal to do it all at once.

you dont need the ecu just take the butterflies out of the IM all together it will flow better.

^^ And you can kiss your low end torque goodbye! The butterflies don't really become a restriction till over 7k rpms.
