What do I need to make a proper R134a AC conversion on my 91TT

Aye, No te chifles guey.

are you running 134 now?? i just did a conversion last week on a 91. the car had a bad expansion valve so i did a conversion.

changed the dryer bottle, (you did that already) drained as much oil out of the system as i could. added a similar amount of PAG oil. evacuated the system, and recharged with 28 oz of 134.

you will need to find your leak, and proceed with repairs first. pretty much all you need to do.
