:wave:[NOTE: Many sections have partial data. Please refer to bottom of page for sources and and links]


I knew a lot of people ask general questions over and over on here, so I thought it would be a good idea to put everything I can into one giant list and (possibly) make it a sticky. If you find any information incorrect, or if you can think of anything to add, please do so, I will update this thing as much as possible.

Huge thanks to tdogg74 and Dan for a lot of this hard to find info, and thanks to Sky-Fi for the vast majority of the PN's

added crank, piston, rod, and valve spring info.
good stuff, you should alphabetize the torque specs as that list will probably grow pretty big a good one to add would be wheel lugs :thumbup:
the simplest answers are usually the best. thx
added intake manifold specs and listed torque specs alphabetically.
do you have that info on the 2E engine?
Its the same as the ABA, although I'm not sure if the obd1 -> obd2 change occured in the same year. Otherwise they're identical.

Mizzuh: You really should reference your sources for this info. Those guys who sit down and take the measurements and put in the hours to provide that info deserve recognition.

no sh*t, right? :rolleyes:
:thumbup:

I'm not saying he needs APA format citation and referencing, but just a shout out as you go along. The thread itself could prove pretty useful and I hope Mizzuh continues.

Happy New Year!
for a start the 2e is counterflow,could there be more differences?
^ Same bottom end though (as well as the ABF with the exception of the pistons). Most of the info for the head holds as well and from what I've read even the valves are the same (so basically just an 8v hydro head with 7mm stems). Euro mk3 4-cylinders also retained digifant fuel injection which was discontinued earlier on in North America. You'd probably be better off searching for information on the 2E in either the 8v forum here (if you're looking to modify and tune) or better yet clubgti which is a european forum.
if anyone knows the injector info, I could really use that

three companies i found make them. but none of the sites ive looked at have the ohms / lb per hr/ or cc's
beck/arnely 155-0226
bosch
and Standard

here is the general opinion of the threads (posted in the main section with a notation beside it for now)
189cc/min
19 lb/hr
44 psi

does anyone have technical data to back this up?
See less See more
Your injector info is wrong. VR6 injectors are 19lb/hr. All 2.0 injectors are 16lb/hr.

I also edited the name of this thread to a more searchable title.

Lastly, credit your info. I see a bunch of info you got from my threads. People deserve credit when they do all the work. Get on that.
thanks. and i put your name on the bottom of my thread , as well as a link to your info a few days ago. im going through my bookmarks and getting it up there piece by piece.

ALSO, added A/C fluid levels and psi's for system
added valve specs and more links. also added some info under the non-catogorized stuff ath the bottom of the list. "fuel and ignition"....not sure what the info is, or where it should go, but it looked useful. anyone have any idea?
These motors arent 10.4:1 compression. They are slightly less than 10:1. (more like 9.9:1)

You really need to confirm your stats before you post them. :thumbdown:
