Hi all got an AUQ top end will it bolt on to the AGU bottom end ? Also is the AGU factory forged at all ? ? Any help would be much appreciated !
Hi it will bolt on but Auq is small port and AGU is large so manifolds won't match up All the info is on this site
Yes along with the intake manifold and other bits bolted to the AUQ cylinder head. "forged" - Vague internet term as opposed to engineering understanding, to suggest an AGU motor is 'stronger' than an unknown 20vT code. The AGU engine runs 20mm small end rods, similar to what what was fitted to a 16v KR engine or a APY/AMK/BAM engine. The pistons are also Mahle 9.5:1 forgings. The rest of the short engine is exactly the same as the rest of EA113 20v motors. The AUQ etc are later EU3 engines, that used cheaper pistons ( with the same CR) and cracked 19mm small end rods to still support power and torque in the region of 180ps@5800rpm and 163lbft@2000-4000rpm. You can still remap these to ~ 220bhp or so with no problem.
As I suggest to simply use the complete AUQ cylinder head on the AGU bottom end. I cannot remember if the 315cc/min EV6 AUQ/AUM injectors work in place of the EV1 282cc/min injectors for an AGU, using the manifold and injector rail from an AGU engine.
Already got uprated manifold and injector rail / injectors for the auq will i still need to use the agu mani and ijec rail and injectors
