G'day Fellas. Just brand new here today. Have built and maintained a small fleet of L Series over the last 5 years and have just put together my first '86 turbo (from various doner cars). Trouble is its running hotter than Im comfortable with in this summer weather we're having down here..
Have done all the usual checks: HG's (no coolant loss, no CO2), flushed, new rad, w/pump, timing ok but suspect the turbo is cooking its water as it idles forever at good temp but heats up quickly when the turbo's in use and recovers when you back off..
So I've become interested in trying to increase the cooling capacity of this and have some questions if anyone would be kind enough to share:
1. Has anybody successfully shoe-horned a Brumby (Brat) radiator into an L series?
2. Which way does the water flow thru the turbo? (Out the top back to the thermostat housing?).
3. Which way does the oil flow thru the turbo?
4. I saw some photos here of a vortex (XT) which seemed to have its bonnet scoop plumbed to a funnel focused on the turbo. Would this be right and did the factory do it for more cooling do you think?
Thinking of putting some extra coolers in line with these but open to any suggestions.
With thanks, (only 1500 pages of topics left to read) Bert.
