B6 Engine Swap Information

Preface:
2005 Audi A4 1.8TQM; Blown AMB/06a.


I'm looking at local part outs on craigslist and found a few engines for sale but they're from automatics (B5 and B6). My car's a manual. Would simply swapping the crank make these swap right in? If so, if I picked up the B5 engine, which is likely an AEB, my AMB crank swaps in, correct?

Sorry if this has been asked to death.

Im not 100% on what needs modifying but if you search you will find to swap to/from auto to manual you only need to modify the crank output shaft sligtly wit a grinder?? Its very minimal and common practice.

Stick with te AMB. The B5 is missing a lot of stuff on the top end associated with VVT.

I saw the info regarding grinding the crank/adding material to it depending on the swap to/from. But I have my old engine and the crank is fine. If I can get away with simply swapping the crank to make the engine a direct swap then I'd be happy.

AEB is an 058 block. You need an 06A. Blocks are different, for example the 058 uses an external water pump. Your AMB parts simply won't install. But assuming you do get an auto 06a block, you just need to shave a part off the crank where flywheel would bolt. No need to swap cranks.

We just swapped a 2004 5speed 1.8T engine to replace a blown 2002 automatic over the weekend. Oil starvation the head caused the original head to fail (badly). The bottom end of the automatic was in OK shape.

We had to swap the crank shaft from the original auto engine into the manual donor. The shaft was too different in our case. I've read of others modifying an automatic crank to mimic the manual one via grinding, expanding the hole, and placing a new (or other cars) pilot bearing. Going the other direction i.e. placing a manual into an automatic, it isn't possible to do this.

I personally am leery of having the input shaft being slightly off center by just grinding the auto crank nub and altering the pilot bearing hole. Off center is no good at high RPM, even slightly. I cannot comment on the longevity of the components without perfectly centering them. People have done this . . . when placing an automatic donor into a manual care, it does work with altering the crank nub.

To be honest . . . IMO, your best bet is to find a manual donor for a manual car and the same goes for an automatic to an automatic, or if your crankshaft is OK you can swap them.

The 2.8 or 3.0l pilot bearing replaces the bushing in the auto crank and adapts the auto crank to manual. No grinding required.
