my 1990 transporter has the KY 1.7 l diesel in it, basically a bored and stroked 1.6. I was going to drop in an AHU or ALH , m-pump it, etc. I can get a long block cheap so it's not a matter of money but i don't have tons of time to play around with. I guess what i'm trying to say is, is it worth my time to change the whole block or should i just turbo, nozzle and intercooler my 1.7 or will there be a real big difference. I do know the tdi's are much more cleaner and efficient, but ... I'm not looking for tons more power if for no other reason than the fact that my truck is as high as a syncro so handling is a bit of an issue; don't want to get in over my head!
