The larger deeper fan is 3-7/16" depth, which is close to 1" more than this fan. You would not be able to use it with the stock shroud unless you cut the thread off the waterpump where the stock fan clutch bolted onto.

There is roughly 1/4" clearance from the fan to the radiator, so not much more room that direction.

The Spal 30101516 which i used was the highest flowing fan i could find that would work using the stock shroud.

For those who have the 1516 spal fan, how loud it is compared to the stock mechanical fan? I am debating the curved 2049 fan. I like that the shroud is maintained with this fan, although I'll sacrifice the shroud for less noise.

Looks like a clean install to the shroud. Any reason you did not use the stock fan controller from the AUX fan to power and regulate the Spal fan?

I did this mod as well thanks to the OP.
From my understanding you can't keep the aux fan if you are using it to control the spal fan, at least no one has figured it out yet. Pretty sure OP wanted to keep the aux fan like I did.

I was thinking of using the aux fan controller, it should be able to run both fans fine, the 1516 fan doesn't draw too much current. I decided it wasn't worth the time to take the front bumper off and tap into the wires, so I just decided to run the seperate thermostat.

Anyone? Waiting for a response to pull the trigger and order.

Not sure I like how that ended up being installed. It's nice to keep the oem shroud and all... but I dont think it helps cool the car. Actually I think this setup is worse than one with a bigger fan, mounted directly to the radiator, without a shroud.

I honestly can't tell it's on, I think the aux fan is louder.
