Difference between AGU and AUM blocks

[Chris.]

AGU has the large port head, but I guess VVT from the later ones could be put onto a AGU?

AUM does have its advantages in terms of mapping software(ecu firmware) as more can be mapped in but then i have to change pedal box etc etc and everything that goes with it.

Im not sure which ECU id run if i went big turbo tbh. AGU is certainly the easiest to put in, but does it map aswell?

i would look into building the head too, apparently the valvetrain isnt all that good for big power so i would look into uprated springs at least.

Surely the VVT will be more beneficial? No one has yet got a VVT on the AGU, but anything is possible I suppose.

What about a diesel bottom end I heard they fit direct, but please check this.

What about enlarging the valves, this could be a possibility, or just look into improving the profile of the valves and seats.

Advantage with the AUM ecu is getting traction working due to the DBW system in place, handy in lower gears with plenty off power.

I know from years ago AGU and BAM have forged internals and take bigger power than rest of 20vt engines.

i would stick with agu, poor r-techs golf .But i blame it on nos.How about bore it out ,wouldnt worry about bigger valve its got 5 in each pot  some good kent cams . Try and get all parts for stage 3 map. Just leave nos out. unless you ceramic coat the valves and piston tops.

wouldnt want to go over 380bhp on the valves like....heat really does kill them!

[james2]

nos wouldnt help.But you should be fine with out it.

The 2Litre stroker kits seem to be a fav amongst the audi boys, 2.0T 20V  now we're talkin'

Now your talking, in a golf would kick arse with a big turbo

If I can fit it into a mk3 a mk4 should be a walk in the park
