I'm in the process of collecting fittings for my big turbo install, so far I have fun numerous posts detailing the fitting sizes an pitches for the oil plumbing, but very little information about plumbing coolant lines to the turbo using the stock passages. I would like to use the stock passages on the block, does anyone know what size flange or size/pitch fitting can be used to do so?

Thanks

 

I've thought about it and you should be able to buy a blockoff plate for the coolant feed (it uses a regular split air blockoff) and drill and tap it, or weld a fitting on. Then for the coolant return you would want to weld a fitting on to the stock barb (6AN). go to www.racepartssolutions.com for weld fittings.

 

What about just using a turbo drain flange? Has anyone tried to use an oil drain flange for the coolant feed port?
