So i know how it works...its just that the only person i know who has even ran this setup had cooling problems when at Oran Park...not sure if its a setup thing or more of an application thing.

Anyway next week im looking to put on an electric thermo fan, and tempted to put the electric water pump on as well, as my currrent one has 80,000kms on it and it needed replacing at 90,000kms.

So anyone wiht experirences with the electric water pump, and maybe even give me some feedback on the Davis Craig electric fan they are running?

The early EWP had some reliability problems. I don’t know what they are like these days. (everybody that got them didn’t use them again after they died). Not sure what the RB motors need in terms of CFM flow, but the Davies crag EWP could not pump enough cfm for a Holden V8. It pumped nowhere near as much as a belt driven pump. No worries if it’s a drag car only, but if it’s a streeter……

mmmm, sounds like i should be sticking with the crappy viscous fan then.... so its the application more then the installation.

Toying with the idea of new radiator, but its the sort of thing that i dont want to spend the money on if its hold coolant temperatures at an acceptable level.

Just trying to get rid of some of the inertia on the engine, water pump, fans, pullies if ican find some...anyone tried RB26 pulleys on an RB20 (Or more RB26 pulleys be used on an RB30DET?) Just lightened and standard drive ratios

Id always assume the parts on the rb26's are better (no bias here :)) Id assume their all the same arnt they? RB20 one has 3 ribbed belts, but rb30 is different though with 1 v groove in the centre.

Interesting though i noticed when my motor was being balanced they took a bit of material off the pulley (rb20 one on rb31det) must be out of kilter after being 10 years old...

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
