Ok so Im about 90% done with doing this swap. Basically s14 sr20 head (vtc delete) onto an s13 sr block. Friend of mine was running the setup and went ls so I bought half of it off him and started working on mine. On this particular setup I converted to the s14 waterneck so I have no hose that wraps around back anymore like on the s13, also eliminated the s13 iacv so no need for water going to it anymore, and the tb is tomei and doesn't have water lines.....also on the s14 intake manifold the heater core line comes from underneath and connects unlike the s13 that comes from the block iirc. Neways I have this picture for reference. I am wondering exactly what way I should go about doing this. I want to keep it as un-cluttered as possible. Ideally I would like to have just two water lines running there. One to the top of the heater core and one to the bottom. But not sure that is possible or not.


Here is the picture. I have marked each line I have there with a number.

Here is what I am thinking....

1. Run to the top inlet on the heater core.

2. Run to the bottom output on the heater core, unless I should change that to #4 and just completely remove that hose and maybe tap the hole and thread a plug in there.

3. Find some way to delete it??

4. Fine some way to delete it??


I was thinking of maybe running a loop to 3 and 4....but the difference in size is quite large, unless I had some way to step the hose sizes between the two its going to leak everywhere. So just asking for some advice. What do you think my best course of action should be and why? Like I said I could just pull that one hose, tap the block and thread a plug....but that's quite a bit of work and I have to remove the intake again and then probably pull the oilpan so I make sure to get any metal shavings out. And honestly that's a coolant passage so Im not sure I could even do that without completely washing out the coolant system a few times and it might be risky....so any help would be greatly appreciated....I got a couple days before I start working on it again. But its out the car now and Id really like to get everything all setup and ready to go before I drop it in the car and have no room to work without the intake manifold off!!

Thanks for any help in advance!
