Alright, I have been looking at 7's for sometime now, but am still torn between the FC and FD. I would like an FD, but the fact that the engine starts to go around 100k compared to the FC's 120-140k, I would rather have the extra 20k. So I was thinking about getting an FD, one without the engine since I would like to drop in a TII engine. Here's my question though, what all would have to be changed out? I know that I would have to get custom made mounts for the engine since the FD's are in the rear and the FC's are in the middle. But what else would have to be changed out.

I am thinking about doing this just because I know more about the FC and my friends know everything about the engine on the FC compared to the FD's Twin Turbo. How well do you think this would work out? Or would I be better off sticking with just a plain FC or FD instead? Thanks

Youd be much better off sticking to either a FC or FD. The whole perception about FDs engines blowing at 100K isnt entirely true. Yes, the 13b-rew is more complex than the 13bt, just in the fact that you have 30 some odd feet of vacuum hoses to worry about. But there have been FD engines that last 150K, and FC engines that only last 40K. Its all about how they were taken care of, and the conditions that they were introduced to. If you have the money, Id get the FD, then single turbo it with a Haltech, and get it professionally tuned, and redo the inferior cooling system. Your engine will then be quite reliable (depending on the power your planning on putting out).

OK, that's one of the more interesting ideas I've heard...

The FC and FD engines really aren't that different as far as reliability. You're looking at taking on a HUGE, bizarre undertaking for the possibility of longer engine life.

Also, keep in mind that the stock FD motor is making 55 extra horsepower than an '89-91 turbo - that's added stress. Add to that extreme underhood temps and a marginal cooling system, and there's your shortened life.

Really, pick either platform and go with it. FD's are phenomenal cars with amazing chassis and great looks, but modifying them and maintaining them is pricey. FC's are killer cars, but aren't on the level of the FD as far as chassis development and refinement. They are generally more reliable and parts are a LOT cheaper and easier to come by.
