looks really good. for some reason i cannot expand the pictures. i see you went a diff route on shock mounts and they look like they'll work very niecely. did you weigh the steel beam front end?   wont be long and you'll be testing that rail.

completely transformed the look of the rail!!   i like them better this way but i may be a smidge biased  ;D

Hi LarryDug,

Tell us a bit about yourself?

Any cool projects on tap?  Prior experience?  

Do you have the winning lotto numbers?

Managed to do a little more on the front end while waiting for the TPS on the other project. Still got a long ways to go as far as bracing and such but definitely making progress. Been a fun project for my son and I.

i would like to know how they are getting the stock tfi to function with all the bypassns you described. i wouldn't believe that to work but somehow they have.

auto enrich ( ae) is like the accel pump shot in a carb. its done a few diff ways but in your case ( with a stock ecu) its done via the vam and or tps. that vam is a very early and poor version of a mass air flow sensor, (maf sensor). they do work but there not as a instant response as tps/map based. my megasquirt ecu doesnt use a maf but rather just a map and tps for ae.

as fabr stated above.....replace the tps and verify it operating the correct voltage range. that should help the stumble. beyond that, would have to know what/why whomever bypassed the tfi. if they truly bypassed it then there must be something else controller timing. i wonder if they went with a mechanical advance from the older carb version??
I bet you would be right.

I am surprised as anyone that this combo runs, not sure why they went this way either. Maybe a cheep way to get EFI on a VW? Not sure really.  I think you guys are correct on the distributor, we bought spare one at salvage yard for parts last fall and it ended up having the guts inside completely different.

The VAM thing is definitely not ideal, i just done know a way around it. I am hoping to get it to run good or at least decent and then figure out how to improve it. Or if not change it over to a blow through carb!

Sorry,I had it in my head you were running the Ford engine with VW controls but it's the other way around. I worked at a VW dealership in the engine/trans dept about 45 years ago. If the head to cylinder surfaces were not good we would lap them in just like doing valves. If that didn't do the trick there were annealed aluminum crush washers/gaskets that we would use. You are correct that there were no head gaskets as such from the factory.

Glad you found the ground issues and the TPS being glitchy. Fix that before you do more to it . You may find all is well then.

My VW engine builder is a close friend of mine, he tried and tried to get the old heads to seal using that lapping method. I even machined the floor of the heads to give a "new surface" and no luck. It was best to make them boat anchors instead of trusting them on this engine!

thats the only way i can imagine. i am not sure why one would go to that amount of time and effort then use a carb mechanical advance??!! the motorcraft tfi modules had lengthy lives. the ecu has an effect on timing and uses tps and vam ( vane air meter) for ae fueling. so bypassing that , imo, was counter productive by that person.   at the same time i feel the vam is no kill mouse trap  :D  but it does work
