I have a 91 12 valve non-intercooled and was wondering if u can put a 08 model cummins turbo on it if so how thanx!!

 

You need a new crossover tube, which means you need flanges, boots, bent pipe and clamps to make it.

You need a flange to go on your exhaust downpipe to mate to the new turbo, which probably means you need a new 4" downpipe as well, which might mean you need a new 4" exhaust system.

You might need a new oil supply line.

You might need a new oil return line.

You need some sort of new air intake ducting from the filter, which is a good time to get a new filter.

You might need adapter plates or a new manifold to get the turbo to hand off the engine.

 

i think you also need a coolant line and a stand alone computer if you want to control the vgt part of it.
