Is putting a 1.8t in a 2.8 a4 that difficult? I know ill need wiring harness and ecu and all parts for motor mounting? Do they share the same automatic transmission? Anyone know of a thread please post here. Couldn't find anything.

easy swap

i did it and have been running it as a dd for 2 years now and no problems.
i did my swap with a 1.8T 99.5 motor and direct plug and play into my 99.5 2.8.
the only 2 different parts you need for the 2.8 A4 is the 1.8T rad support and power steering hose.
you only need the engine wiring harness up to the ecu beacuse everything is just plug and play with the 2.8 car.
it took me about 13-14 hrs to pull the motor from the 1.8t car and pull the 2.8 then install the 1.8T into the 2.8's body.
i used the 2.8's tranny instead of the 1.8t.

The tranny worked no problem? Did you have to do anything special?

1.8t and 2.8 both use the same 01A manual transmission.

Why would you want to swap a 2.8 with a 1.8?

Why would you want to swap a 2.8 with a 1.8?

Because it is way easier to get power out of a 1.8t.

Exactly and I can pick up a clean 2.8 with ratty interior for 500 possibly

Do a 5spd swap while your at it

Auto trans fits both 4 & 6 cyl too.

that would be the plan, i'm still waiting to see if the sale will work out with this a4. its a 2.8 in pretty rough shape(leaking valve cover, high miles, and exhaust leaks). The only thing cosmetically wrong with it though is a dent in the passenger door. besides that and a little dirt it looks pretty good though

i've gotten pretty good at popping dents (my a4, and of course the horrific golf tdi incident :banghead

you need to swap the subframe, ecu, engine harness, exhaust, flywheel and clutch
