Heater Core Delete

[ctnewman]

There is no heater core in the car I am putting my RB26 in.

I searched around a little bit trying to find an answer to this question, but was unable to.

I know a lot of you guys loop the lines and that works, but I'm trying to find a definitive answer as to what the best course of action is for a high performance application...

The heater core provides a fair amount of resistance to the system. By simply looping the lines, you create a "short circuit" from an area of high potential to low potential and could rob coolant flow from other areas that need it...

Can anyone shed some light?

You can see the heater feed/return in this pic:

The return is the nipple on the tstat housing. This is "low pressure".

The feed is on the block to the left.

The more I think about it, I should loop these, or else the pump will cavitate when the tstat is closed....
