This is awesome Sharif! Doug told me about this a few weeks ago when I was talking to him about an engine build. It's really great of you to offer the details of this find. You deserve some kind of compensation for putting this kit together!

This is a low cost alternative to the Pathfinder bypass
2 x 5/8" heater fittings tapped in to the manifold & blanking plate
Without a thermostat it will flow all the time, but a lesser amount than the Pathfinder solution.

That's a pretty good idea, too.. However, I would weld in some aluminum barb fittings, to minimize the possibility of leakage.

Looks like a more restrictive fitting, but it certainly would work.

FYI: Doug at Crawford Z is also going to carry the kits in stock for resale. Some of you had PM'ed me for the kits. Feel free to give Doug a call and he can ship you kits as well. My main intention for this post, was merely to point out this modification. I dont plan to actively sell the kits, but I will have some in stock for customer specific cars.

Does this get in the way of the return fuel system at all ? Or the fuel preasure regulator ?

No, it does not interfere, or require modification to your return fuel system.

Hmmm - I am wonder why you need this, I am FI and Track my car and have NEVER had a temperature problem, even in the hot Georgia summer? Maybe I am just lucky, I don't know, but even when it was 97 F my oil temp never got above 190F and my water temp never got above the half way mark, and that was stressing the engine for over 20 min constant.

Plus, coolant cooling comes from the radiator, your engine under a given load condition will give you the same heat to the water regardless of this passage. Now if you are saying that there is a problem of a hot spot in the engine, than I can understand this mod.
But, if you had coolant temp problems before this, most likely you will still have them after unless you do something to increase the cooling of the coolant.
Still think the best cooling mod for FI is an oil cooler!
