you have reason to believe the engine was changed? should be rd
HT motors were used in 85 GTI/GLIs, although I'm not sure if it's the same for Canada. The RD superceded it in 86, although there aren't really any major differences that I'm aware of. The RD has a better cam and 4-2-1 exhaust setup. The HT had the 4-1.
Not sure if that sticker means it's an HT or that it can be swapped in place of an HT without issue. Do a compression test and you should be able to semi-conclude whether it's a high compression motor or not.
I really suck at smog.
So i can check the compression or simply check the exhaust setup i gather?
Thanks again for the info
