Ok so I'm trying to go N/A-T. I plan on running coolant from the back of the water pump (thermostat?) housing to the turbo and returning it to the nipple on the lower radiator opening (used for heatercore, which I no longer have). Plan for the oil is to tee it off the oil pressure sender and return it to the oil pan. Everything sound good? My question is, what size for the lines? I'm thinking 1/4" for the oil but i'm not sure on the coolant Any advice would be appreciated.
TIA

 

damn aaron or sonicrat care to chime in?

 

Probably not, because this is all covered in the writeups.

And not to be a jackass, but if you can't answer this question then the rest of the project might be a little too difficult.

 

I'm turboing my N/a, and currently this is what i'm doing.

Oil Lines: Install an aftermarket oil pedestal and tap into that for the turbo oil supply. As for the return, use the default location on the front cover*SEE BELOW*

Coolant lines: If you install a TII waterpump you can use the coolent supply on the back housing for the turbo, and then from the turbo to the nipple on the waterpump.


*This method requires the use of a TII front cover.*

 

^ he is right, if you have no idea what your doing, I HIGHLY advise you to not do this. That's not to say you shouldnt do it if you just don't know how, as everyone had to start at the beginning at one point, but if you do attempt it, make SURE you know your way around the engine bay.

The Only time I would recommend this conversion is if your motor is 100% healthy and you want to avoid the price of a turbo motor because you already have a good one. Not to say that it's a bad swap, but it's generally not the best idea if your motor isn't healthy.

 

In a slightly better mood now so here's another answer...Use the nipple on the back of the water pump housing and the nipple on the rear iron for water supply.

For oil, see this:

Yeah I was trying to avoid using the nipple that goes to the TB (this is what you are referring to correct?) because hoses like to cook there. Maybe I will do that. Thanks

 

If you have the proper heat shields on the turbo, manifold and downpipe (or heat wrap) then it should be no big deal. Those nipples are easy since they are already the right size. The heater core connections on the engine and rad are much too big, and you end up with a LOT of hose to connect them.

Coolant hose is designed to take the heat anyway...
