Hey guys.

>From what I read the coupe quattro is in fact two speed motor but seemingly putting in a 3 speed motor should not be a problem. 

Well that is with a fuseable link, relay, and breaker?

I am thinking of putting in a 50amp relay infront of all the wiring with a breaker like on the rs2 headlight harness from 2bennett on a power feed to the allternator, and a 80amp fuseable link probably grounding that on the abs/brake grounding point.

fan motor? I am not sure yet.
But I like the idea of jumping up to a 352mm fan blade.

I'll keep everyone posted on what I end up doing.

Cheers
Josh

The only problem i had with 4 blade is the noise, It is ungodly noisy, even sometime, I had to shut the car down if i want to order food from drive thru. I also put lower temp fan switch (the three prong swich in the lower parts of radiator). The low fan speed turn on when the gauge just almost reach the first thin mark of the temp gauge.

Thinking about going back to 3 blade instead of 4 blade. I also not really sure if the 4 blade will give more flow since it might make the fan motor more work, thus lower rpm on the fan motor to turn the 4 blade fan.

Hi Josh

I'm not sure where i get the 4 blade fan from, but i believe I got it from 80-84 rabbit. i got it from pull yourself junkyard in my town, they have really good selection of vw and audi.

The diameter of 4 blade are the same with 3 blade, which work perfect. The only problem i had with 4 blade is the noise, It is ungodly noisy, even sometime, I had to shut the car down if i want to order food from drive thru.  I also put lower temp fan switch (the three prong swich in the lower parts of radiator). The low fan speed turn on when the gauge just almost reach the first thin mark of the temp gauge. 

The original radiator made by behr, the replacement radiator i got is AKG, it is plastic cap and aluminum core. I got it from rod at Thepartsconnection.com I also ordered the new radiator rubber mount from him. I went with akg since it is lighter and according to Rod, AKG built much better than Nissen. 

Until now i dont really understand why the 7a engine only have 2 speed while other smaller vw engine have 3 speed fan, even my 16v 1.8 have 3 speed fan.

More info

Sport quattro:
443959455h

700w 352mm

This thing is an animal :-)If I am understanding this right? 

Etka also states that the sport quattro uses the same fan cowl as the 7a motors.

859 121 207a for the sport quattro and
893 121 207a for the coupe quattro but the first three #s don't matter. 

This motor is preity expensive too btw: 
$413.00

So am I understanding this right? 700w = 700 watts?

Cheers
Josh
