You don't need to spend $6,000 for a 2v turbo kit. Matter of fact, you don't even need to pull the exhaust manifolds.
What you do need is time, supplies, and the ability to weld. An aftermarket K-member/a-arms WILL make things easier, but is not "needed" unless your car is sitting low.
The hot side is the complicated part, like said above, but with some brains and elbow grease it is a do-able project by a competent wrencher with welding skills.
All you really need is a merge pipe running from the drivers side exhaust manifold, into the hotside piping coming from the passengers side exhaust manifold. Run it under (if using stock K), or through (aftermarket K) the K-member, and up into the engine bay with the turbo sitting between the front of the engine and radiator. Hot side done...
That eliminates the need for modifying exhaust manifolds, flipping the stockers (doubt it would work because of the lack of space under our hoods where the exhaust manifolds are), or buying/installing turbo manifolds... yadda yadda yadda.
I got really into looking into a DIY turbo setup for my car, but I am missing two things. Money, and a welder. Can't get a welder without money, so I am putting the idea on the back burner for right now as I have other stuff to stay ahead of $ wise than the car...
