They are made of kryptonite. So is the rest of the drivetrain. The
weak link, it seems, is the clutch - at around 400 hp or so it starts

The engine will bolt right in - mounts and transmission hook up are the
same. I believe the port side tie rod has to be bent or replaced with

What won't "bolt right up" will be the exhaust system, engine
management, and any oil cooling/intercooling doohickeys you want to use.
People have run them with the stock CIS-E, but you're pushing your luck,
and, you are going to want to up the boost once you have boost.
The stock system from the donor vehicle will get you quite a way, and
comes free with the donor car, but is a complicated pain to remove and
So, depending on your budget timing, you might want to go to a stand
alone EFI/ignition system fright from the start. At this late date

advantage of a deep resource of btdt experience, *and* far more options
to throw money at that make your resulting car better and easier to work
If you actually enjoy working on major systems over and over again, you
can spread the spending out by upgrading and replacing systems over time
as you investigate and can afford them. If you want a basically
"turnkey" car that you can enjoy the heck out of without always thinking
of things to add (yeah, right), you spend more up front and go with the
proven goodies from the start.
