Hi
Right interested in getting a engine from a mate which is a AUM engine code, I have a AGU engine code.
Now, im wondering what the differences are on the BLOCK, not the head or sensors or whatever else, just the differences between internal components. I know the rods are thinner, but not sure about things for crank, and other stuff you get down in that area.
Just want a engine to build over the winter as a LONG term project to getting more power out of mine (ie big turbo) Id build everything up on the aum then swap manifolds and put everything made onto my AGU head i currently have now. although a AUM engine loom and ECU would probably be more beneficial. Hmmm
Any ideas?
-
Agu are a stronger engine forged as standed
-
Aint that just a rumour? Which parts are forged? I know they use mahle pistons.
-
If your doing a rebuild then it doesn't matter :laugh:
-
Thought so.
Just need to find a cheap 1.8T block now really.
-
i would use the agu engine ,but get the turbo off the aum and put it on the agu.Grind all the valves in and clean head and pistons, and gas flow the head whilst its off. :drool:
-
Already got a k03s AGU engine.
Want a spare block/head i can work with over the winter/next year building up for a big turbo. There is always a time when ~230bhp really isnt enough.
-
Try and find a R 32 engine. :laugh: Wonder if there are any bigger turbo engines that will fit in the golf. :undecided: I would build up a AGU .up to you. :nerd:
-
If theres no difference then i can buy any block?
I did say in the first post id be building engine bottom end and manifold up on the spare engine then swapping the AGU head onto the new block and sticking manifold and turbo onto AGU head. ;)
-
If its gonna be rebuilt why choose an agu over an aum? isn't electronic throttle better, and the rest would be pretty much the same?
-
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 :laugh: some good kent cams . :drool: Try and get all parts for stage 3 map. Just leave nos out. :laugh: unless you ceramic coat the valves and piston tops. :tongue:
-
wouldnt want to go over 380bhp on the valves like....heat really does kill them!
-
nos wouldnt help.But you should be fine with out it. :wink:
-
The 2Litre stroker kits seem to be a fav amongst the audi boys, 2.0T 20V :smug: now we're talkin'

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

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