Just thought i'd report back my progress....
After getting my new hub assembly from Repco and them being adamant that it was to suit Skyline RB26...suprise suprise, it didnt fit!!!! The GTR fan did not bolt up to this hub so I tried the RB30 fan on this new hub after modifying (read trimming) the RB30 fan, the fan fit but once I got it bolted up, it fouled on the crank pulley as the offset was all wrong (the snout was alot shorter than the original 26 hub)...
Anyway, my 16" thermo arrived the next day, this fan was advertised as flowing 2850cfm.
Heres what I did -
Determine position fan will sit.....
Drill holes in shroud and apply the zip ties! The fan is very light so Zip ties positioned at various locations around the shroud/fan hold it nice and secure.
Take your weather seal strips....
Apply some No more Gaps -
Now I know many will scoff at what ive done here but it looks neat enough sitting in the car, you cant really see any of it anyway.
A word of advice, you need to sit the fan in another 10mm further than I have as the only issue I had was with it sitting too close to and rubbing on the pulleys!
We wired it up today, its currently running off a switch with the Air-Con Aux fan (so one is pushing, one is pulling - today it easily cooled the car from 86c to 80c while stationary).
I will soon get it running off a proper sensor/switch so I dont have to keep watching the temp, although the car does not get hot when its moving anyway.
The biggest plus is, no more noisy locked on clutch fan, robbing HP and killing fuel economy and the thermo with wiring was only $99.90 delivered.
