Hello everyone, I am in the market looking to purchase a mkIV. The only problem is, is that I am not completely sure on which I would like to purchase...na or tt. I have done some research, and I am sure theres alot of information that I am still missing, but I still am unsure of what to do. I know that I want a tt, but I would really like to convert an na to tt, maybe buy an n/a shell/roller. I don't really know. I know that price is the major point to look at. If i bought an n/a shell for around 4 or 5k and transplanted the 2jz-gte and the getrag 6 spd that would cost anywhere from 3k to 9k from what I have seen in my research, plus the expense of a tt wiring harness? Ive read that the tunnel for the trannies are completely different, and ive read that the heads of an n/a and tt flow completely different, some places even say that the n/a head flows better than the tt head. I work with a guy that owns a white mkIV who also told me the same thing. He did the na to tt conversion but paid a pretty hight price for his n/a, which in the long run ended up costing him more than it would have to have just bought a tt instead. So at this point I am stuck in the middle and in one hand I have the n/a to tt conversion if I could do it cost effectively, and in the other hand I have just buying a tt and starting there, but I don't want an automatic whatsoever, period, so that makes buying a tt that much more expensive. i would appreciate all the input and advice that I can get! thanks everyone!
