6 Bolt Block 2g Head Water Pipe

[ChunkyLover53]

I could not find a clear answer about this. I need to know if I can use a 1g Non Turbo water pipe with a 6 bolt block and 2g head setup. It seems to me like there is no question about it fitting the water pump side, but I am wondering if there is something about the thermostat housing side that will not work.

I am using a 1990 style Oil Filter Housing, and a turbo that does not have water provisions. I also am using a 2g Thermostat Housing.

You can go either of two ways, the 1G & 2G tstat housing will BOTH fit on the 2g head. That being said, the type of tstate housing you use will determine if you can use the water pipe. To run a 1g nt water pipe, you will need:

1G NT water pipe
1G thermostat housing
1G (or modified) lower radiator hose

Any waterpipe will fit into the water pump and heater hoses just fine.

Excelent thanks for answering my question. When I do this is there a coolant feed/return location on the engine block that I have to block off as well?

Part of this is incorrect. Either a 1g or a 2g thermostat housing can be used on a 2g head. However, a 2g thermostat housing can NOT be used on a 1g head.

Chunky - Since you are running the 90 oil filter housing your best bet would be to get a 90 front water pipe. It has only one water outlet fitting which is used for the stock coolant line to turbo. This is a threaded fitting so it can easily be plugged with a 14mm X 1.5 plug or bolt since your turbo does not require coolant. You will then use a 1g thermostat housing and 1g lower radiator hose. If you go this route you will also need to cut off the stock weight on the 2g front shifter arm so the lower radiator hose will clear. Of course if you dont want to go through all that hassle, you can just use the 2g thermostat housing and front water pipe and just loop the old coolant lines that ran to the old internally cooled oil filter housing if you wish and everything will work as it did before. The only real advantage to using the 1g setup is that its alot cleaner due to not having any old oil cooler lines to loop up. Hope that makes sense.

If you wanted to go further and not plug anything, you would use a 90 n/t water pipe. No provision for water pipe which will be less of a chance for a leak than a plug.

Thanks for the great info. It definately clears things up. The reason I asked the question is because I have a 1g Non Turbo Water Pipe and Thermostat Housing at my disposal. I don't really want to spend money that I don't need to right now. I will go ahead and remove the weight on the 2g shifter.

Ah yes, you are correct. I almost had it all covered

You're telling me! Man I'm slippin huh? Glad you guys got my back when I fudge up a bit It's kind of like a square is a rectangle, but a rectangle isn't a square. Oh well, post edited.

I didn't want to start a new thread for something so simple, but I'm going to be removing my water pipe because it is leaking. I was hoping that it would be a simple process without removing too many parts. I was unable to find a '92-94 water pipe for my swap so I had the shop use a '90 water pipe and they ended up slicing it in half using radiator hose to connect the two.

Is it necessary to drop the turbo in order to remove the water pipe? BTW I'm running a 6-bolt with a 14B, so I have the provisions for the turbo and the oil pump.

im not sure if theres anyway around that. I had to take my turbo off because it seemed impossible to take off the water pipe from the bottom and this is a 7bolt block at the time.
