which water pipe do I need

[iceman69510]

To eliminate the lines to the water/oil cooler, which water pipe do I need? I looked at CAPS for the 1990 turbo line, MD147684, but some others have stated using the non-turbo pipe. Wouldn't that one be missing the fitting for the turbo water cooling line (which I am keeping)? That one appears to be MD136572.

I may just cap off or weld shut the line to the water cooler and not replace it, since the pipe is in good shape. I suppose that will work just as well.

Thanks.

 

Well since you are keeping the water line, and elminating the pancake cooler then a 90 Turbo pipe is what you need
Hope this helps

Sam is right. The NT pipe is for those of us running an "oil cooled only" turbo.

yah, and make it REALLY clean, and get the 90 tstat housing, too.

jspec one!
or the pipes from the air / oil cooler

why dont u just plug that end up?
thats what ill be doing.

I welded mine. It was easier than trying to find the '90

 

I did the same as powerplay. I cut off the tube that supplied the oil cooler/filter housing as well as the small nipple coming out of the tube that supplied coolant to the heater core. Now I have the main pipe, the long piece supplying the heater core, and the small nipple that's meant for a water cooled turbo.. It's simply corked with a threaded plug.

Yeah, I forgot that part Ken. I acutally got a NT one from Tom and it worked perfectly. A fitting with a hose on it and a bolt hoseclamped in it cost Doug Thomas his entire car when the bolt blew out at the end of the track during what would usually be an 11 second run, coated his tires with antifreeze and sent him promptly into the wall. He was the original owner of his GVR4 which was the first one I ever saw and that's what got me lusting after one of these damn cars.

The 90 t-stat housing for a turbo, or non-turbo is the best choice? Using the non-turbo eliminates another of the water outlet pipes, leaving just one. Which other one is eliminated?

I wondered what happened that Doug was parting out his car.

The NT housing gets rid of the one that feeds the water to the turbo so you wouldn't want that one. Yeah, its a shame about Doug's car, he's a really nice guy. I saw him at the TTR shootout this weekend and he's got himself a nice new Evo now /ubbthreads/images/graemlins/grin.gif.
