Hi guys, got a question for you: Does the vw 2.0 ignition module on the coil handle all ignition events--or does it also go thru the computer???

I have access to a very stout 2.0 and am thinking of putting it into my teener--would like to run a stand alone ECU for injection only if it is possible---

Comments???

Almost any motor that is OBD II compliant has ignition that is controlled
by the ECU. Not sure what your setup may be but there are some good
tuners in the watercooled world that can give you a custom chip as
aggressive as you want.

There are aftermarket supercharger kits for some of the 2.0 motors
also.

If there is no vacuum advance can on the dizzy then timing is thru the ecu

I have an intesest in the watercooled engines, as I ran a little 2.0 8v tricked out in a rabbit for a few years...but the question is what is the cost of the coversion including the motor, radiator, tranny adapter, fabbing mounts....etc etc and afterwards what is the horsepower gain/per dollar.....one big question is what type of weight difference between a hot water 2.0 and a hot air 2.0......I agree anything can be done a 16v 2.0 looks like it could be a lot of fun and a reeeely hot 2.0 should net you some decent horses my 2.0 8v prolly got 140 but the cost was close to 2500 Cunuck bucks, given a 16v will do better untill the valves pile ......................I am sure Jake could help out with your HP delema for a hot air four ...... but "shall I say six"

depends on what 2.0 motor you are talking about.....i have the feeling he is talking about the wasserboxer flat 4 bus motor....just run the ignition off the stand alone ECU, normally the cost is about the same either way....

Naw--it is outta a jetta III --- the dizzy looks very much like a standard 009 unit---wonder ifn they just drop in....prolly use the same drive flange.... Would be cool to use a standard dizzy and mount up my dual webbers with a kick ass header----prolly make some good power...

seems like a lot of work for 150 or so HP........

Not really--actually less--I would not have to disembowel the ecu harness and reconnect everything up----when the top manifold is removed the bottom runners-( leading to the intake ports ) would need only a mild massage to bolt up my duals--prolly take a welding shop about an hour to complete---then I would have a one wire very high amp alternator and only the power wire to connect to the coil and my crane ignition---

Actually, now that I think about it even more--this would be too easy to do--have water heat for cold days--and a proven bullit proof engine--about the same weight--and very decent hp-tq numbers----

I would be very interested to see pics......take a lot....it would make a great thread....best of luck

Timing is handled thru the ECU for the Mk.III ABA (2.0L) engine.

My Jetta 2.0L puts out a dyno'd 102whp. http://www.icbm.org/erkson/personal/mycars/jettastats.htm

That is true, and it's a high compression engine that relies on the knock sensor to keep it all happy. So that could be a problem if you try to run it mechanical ignition and carbs.

I've got a 87 2.0 ABA in the http://www.evcl.com/vw . Works pretty well, but watch out since some (including mine) were subject to a recall which I hear involved honing the cylinders. I got it with 2000 miles on it (before the recall) and it burned 1 qt of oil every 1K miles. Now after 80K miles it burns a quart in 500 miles. Time for a new engine. I don't think I'd use one again.

I am currently working on a 1.8l Corrado G60 motor for my 75.
The facotry G-ladder has been replaced with a twin screw
lysholm the is a bit more efficient. Mad compressor whine
though so I will have to look into that.

Yeah sounds like alot of work but the motor probably will last longer
than a 200hp IV and will be cheaper to rebuild. Plus at 5700ft elevation
FI has such an advantage. We are talking 15-17 percent power loss
for NA.

Hi
I just stumbled over a old European car mag, 1998 vol 29 #9.
Theres a large rite up on Eurospec in CA, swapping the 2.1 waterboxer for a golf motor, OBD2 and Ca compliant.
Motor had to be angled in the hole, heavilly modified pan and oil pick up. I have to say, looks real good. Using 100% oem parts !!! The big question was "was it worth it" ? Some quick specs
2.1l waterboxer 94 hp 117 lb-ft
Fragile heads, lifter problems
Can be machined tuffer but is a problematic motor.
rebiuld complete - 3000$ can
The last one left my shop with a 5000$ bill (extra work on cooling system/injection) always something else.
Sound familiar
Its a 5000$ usd turn key price, with warrenty on the rebiult motor. Chip tuning alone will give 122 hp 135 ft-lb, on a bone stock motor.
Back to the question, this is a dirrect quote from the writer
"Just knowing that the motivation behind me was a Golf mill was eminently reassuring. Its a motor thats very hard to kill, capable of living a long time in start/stop conditions. Thats the type of usage the flat four did not care for. Big question is the car worth it, I say YES"

Seems pretty close to a 914 for reasons to swap. Problem with the VW mill the more you mod the less its reliable. Its really a cool article but I am sure Otmar has seen it. If not I can scann it ... or send you the mag.
Sorry for being a little OT but when the topic goes to the SWAP dirrection, I start to ramble. Hope this usefull for someone.
Regards
Joe

A local shop has done at least five of those conversions and the three
customers that I have actually talked to had nothing but good things
to say about the end result.
