I have a 93 W250 5 speed. I want around 300 hp and I don't want to blow a @hit load of smoke. A little smoke is OK but no coal. I am going to go with a wastegated turbo for a couple of reasons but I don't know what size to choose. Compressor wheel size and exhaust housing size I am unsure of. And ofcourse what injectors to use that aren't smokey. Is the M&H timing spacer an advantage with what I am doing or is it only to help ignite huge injectors?

Right now I have a Denny T stage one, 3200 spring and the pump turned up just a bit.

Thanks for any advice.

 

For that power goal I've been hearing alot of good things about the Variable vane turbos off teh new 6.7's. Some guys are running them on 1st gens with a homemade set up to activate the vains.
