AGU build thoughts :)

Engine wise.. Probably a GT28 although I have seen someone make just over 350bhp with a good K04 hybrid, Rods (I.E makes decent ones), possibly uprate the exhaust valves. Someone like Nick at R-Tech/Bill at Badger5 could give you more of an idea of the injectors you'd need. The engines are pretty strong, its the rods that are supposedly the weakest part.


Then work on flow, good intercooler core, 2.5" IC pipework, 3" exhaust, probably a relentless manifold or similar, WMI, good TIP.

Just dont forget, it's all good and well having 350bhp, but if it was me I'd certainly want bigger brakes, and probably upgrade the suspension set up too. Im sure alot of people would also advise an LSD at that power.

Injector wise for the AGU you want Bosch 440cc (green giants) or bigger ones Siemens Deka 630cc

Prawn is the only one I know of who has made 350 true BHP on a K04 Hybride.

He's only here every now and then but your best bet is to have a look over on ASN. They have come up with a formula that works well. The AGU engine is the best starting point and I've also just bought one to rebuild. Here's Prawns build thread to have a good read through. It's a must read!

Prawn was the person in question

K04 hybrid and look for usable power over a great range rather than a peak figure

WMI, Relentless manifold, Wellycooler with 62mm pipe work, B5 V2.2 TIP, cone filter, 3" DP with de cat and then turbo of you choice. Oh and a trip to B5 or r-tech for a map!
 What rods do you have planned on using? Also worth fitting new piston rings.
