Currently doing an aristo 2jzgte swap on my 95 na auto, so I called the shop a few days ago thats doing the work and they tell me I just need a gasket for the downpipe and I'm all set. the gasket would arrive on wednesday morning, so I had to work all day and didn't get to call about my car. The next day, I finally cal and hear that I now need a maf....??!?!?! Wth I thought aristo motors use a map instead of a maf? Do I really need that part? Can I just stick with the map?
