Whats cheaper?

buying and putting a turbo into a stock SL? or... buying and swapping a VR4 engine in? The reason im asking is because ive heard that it costs alo0t to modify an SL engine to add a turbo in there. Thank you

Its wierd, I once quoted a couple of different places like GTpro who actually sell kits to turbo your car but I dont know what the kit includes becuase the site is really crappy. then every body on 3si.org says that it is actually cheaper to get a vr-4 then to turbo an SL. I did the calculation but I figured it buying the parts all seperate and building it up as a turbo. i.e. manifolds, housings, heads, pistons, I.C. ect.. the tally came out to about $10.000 in parts alone. compared that to the price of a slightly used VR-4 (plus all the vr-4 benefits:AWD, Electronic Suspension, Active Areo, Ect...). There is the matter that the SL is a 5-speed and the VR-4 a 6, so you might have to swap the tranny too if you drop in a vr-4 motor, also are the diffs the same? what about the ECU? anyhow in the end its cheaper to just buy a VR-4!
