I am using my 160f thermostat gutted as a restrictor.

I dont have any heating problems with my L20 setup but if it ever start getting a problem you guys have given me a bit to think about. Thanx!

my 140y was overheating yesterday, above the high mark of the car, not sure wats causing it, as the radiator is full off water, had my radiator recorded about 2 months ago to a 3 core, taking my water capacity up from just over 2 litres to over 4 litres, surely there is enough water, almost half gets lost, i see no leaks, I believe my thermostat has been removed also, I'm thinking its the waterpump that has the problem. Also when I filled the water up and ran the engine, bubbles appeared big ones and also small ones making a bit of a frothy look. Any ideas?

Hi TJ, post a new Topic for your question. Unless it has something to do with high RPM water pump modifications it should be a new Topic.
