Very possible, I just did one but with the 16v. I'm down to the point where I see that I should have used a Sami compressor and not a kick compressor r/t line fitment.
Will you be using power steering? If so its very tight but still possible.
Do you already have the AC system and bracketry?
I have the AC direction scans, it was added as a dealer option and I got the entire system from Mikoda industries for a very reasonable price, less the comp.
I may be offering up the AC face assembly, I'm using it now but it's not quite right for the custom dash. I'll probably be going with universal cable pulls and a universal 3 way switch for blower, toggle for AC.
The few others I have spoken to have had good luck with this install except in cases where 134 was used as a refrigerant, R12 is spendy as hell to but works better, I've had several recent conversations with guys that have used Difluoroethane cas#75-37-6 (dust off) and had slightly better results than even R12, aside from being dirt cheap and readily available. I'll be trying that in the coming days as I complete my setup. I'm looking into what it will cost to bring this vehicle to the Philippines with me when I go so I'm looking for this to work as well as it can. Let me know if you consider it further and I'll send you the scans so you can have a closer look at whats entailed. It really isnt that bad at all, hardest part being squeezing it in there with PS.
