1.8T 5000tq engine swap

[Ken Keith]

Seems to me the poster was asking about putting a 1.8t motor in place
of a 5 cylinder, not a drivetrain swap.  Since most 1.8t's are mounted
transverse (except for in the A4), the question of going from
transverse to longitudinal are referring to the before and after
orientation of the motor itself from car to car.

I think a 5ktq would be too heavy of a car to bother, but if you
fabricate motor mounts I think it's a doable project.  I heard the
motor should bolt up to the 5ktq tranny's bellhousing.

If it was a Type 85 or 89 you could probably use the subframe from the
4 cylinder cars to support the 1.8t.

I think the main issues would be things like flywheel/clutch, engine
mounting, wiring, and maybe oil pan/sump stuff if the angle of the
motor was different enough to cause problems.  Then, if it's in a 5ktq
there's the matter of not having enough power to make it go
satisfactorily.

I have a 4 cylinder fwd 90 that I'm parting out, and a Coupe GT I'm
not using.  If I had a 1.8t I would be tinkering with a 1.8t'ed Coupe
GT with a big FMIC.  I think it would be better balanced and pretty
light and quick.  It wouldn't have that cool 5 cylinder sound, but I
think it would be pretty cool in its own right.

Cheers,

Ken

There is no way to mount the motor in, totally different mounting designs.
Also there's no way to attach the motor to the wheels to make them turn. The
layout of the cars are not even remotely simmilar. The gearbox in a
transverse 1.8t has the axles running just under and in front of the engine,
where in the longitudinal 5k it's axles are about 18 inches behind the
engine. I don;t even know how to explain how different they are :-). The
thing is though, that Audi A4's have the same 1.8t engine mounted
longitudinally, so there is a possibility that that would work if you could
figure out how to bolt it to the transmission and like you said have fun
with the wiring.
