2.2 sohc......garret T4 turbo.....inline 4......
the turbo 2.2's were available in daytonas to k-cars, as the years progressed they got better and better, what to do/not to do was learned by dodge. they have a dohc engine (TIII, the head was built by lotus) which is the cats meow, these twin cams came in early 90's dodge spirit RT (only a few thousand built) and some of the iroc daytonas.
now that it's been 10 years dodge diyers have figured out "the way to do it", and documented everything along the way
