Just bought a 1.8 8v long block from a guy who claims it was out of an 87 Jetta GLI. From what I was able to glean from a number of sources (some contradictory), the GLI was available in both a 16v and an 8v this year, with the 8v being the 102hp "RD"
engine with 10:1 compression. I also understand this engine has CIS-E. I was wondering if anyone knows a definitive way to tell if this is the RD engine (serial numbers, things specific to CIS-E, etc). Any help is appreciated.
