Subject: 2.0L engine swap is done... WOW!
Content-Type: text/plain; charset="us-ascii"
Well the engine swap is done - gone is the 70hp 1.5L Audi Fox engine and in
is the 115hp 2.0L Audi 80 engine. Total swap time of about 12 hours from
start to finish
The swap went quite smoothly, as there was a lot of prepping done outside
of the Double Cab. I did the wiring harness from scratch and made the fuel
pump relay "black box" that interfaced with the CIS-E knock sensor and hall
controller before I took out the old engine. This setup works quite well
as there were only 8 inputs needed to make the whole engine with knock
sensor run:
- Ground
- 12V unswitched
- 12V switched
- 12V while starter is on
- Water temp
- Oil temp
- Oil pressure
- Fuel pump
Bolting the engine in place was quite uneventful as I already had the motor
mounts and cross member designed from the previous install. Swapping the
KEP engine adapter and flywheel / clutch was also quite simple. Installing
the vanagon 90A alternator and vanagon power steering was a little
challenging but nothing too serious!
After bolting the engine in place and connecting the 8 wires to the
existing vanagon wiring harness it was time to connect the exhaust, coolant
lines and fuel injectors and then turn the key.
I must say that the Audi 80 2.0L is a very nice, smooth engine! I took the
truck down my 500m driveway and did a little off-roading in the ditch and
then drove back up the driveway again. This is the first time that my
Double Cab actually set me back in my seat! Not the gut wrenching 6.5s 0
to 100k that my Rabbit Pickup can do but still enough to spin a little
gravel and to draw comments from the wife!
Currently the timing is 4deg ATDC so there is still some work to do which
will only make things better! Tomorrow after I get insurance I will take
it for a road test. Hopefully I can make it up the 2km 18% grade and not
have to drop it out of 4th gear. With a few trick like 12deg DTDC initial
timing and no catalytic converter and a free flow muffler I should be doing
about 130hp and 140lb torque.
