Alright, goodish news on headers. JBA headers for the 04-06 GTO fit... Mostly. Physically mount just fine. There is spark plug interference on the passenger side. Also, the flanges kinda point towards the subframe. I think there is enough clearance for the exhaust guy to make it work. You have about 4 inches linear distance between the flange and the subframe to make something happen. Should be fine

I used these fans

https://www.summitracing.com/parts/s...2043/overview/

And this relay kit triggered by the factory wiring

https://www.summitracing.com/parts/cir-33-10220

Works great.

Not sure if the factory wiring can support these fans, didn’t want to chance it.

That's what I was thinking.

That wiring kit send kinda pricey for a couple relays, no?

I had the slim fans from Fullblown. Asked around, @ILLSMOQ helped me tremendously along the way. Ended up getting these

https://www.summitracing.com/parts/spu-ix-30102029

They're the same bolt pattern as the super slim included on the FBM kit, but pull 40% more air each.

I used the stock wiring, but needed to raise the fuse amp on both to the next rating, from factory 25A to 30A this was suggested by other owners who had raised the fuse and had been running it for years (they do trip the 25A fuse, but are fine on the 30A). So far so good. The relay kit @ILLSMOQ used has the advantage of already having the correct spal connectors, higher amp in line fuse and bigger wire.

Did you guys need the slimmer fans or did you have extra clearance? Are the fans the same thickness all the way across or taller at the motor? Obviously the interference area is at the crank pulley so taller motors wouldn't matter

I had clearance, but it would have been extra close with the stock fans. These fans are the exact same as the slim fans provided by FBM, the only difference is the taller motor.

I'm not looking to use stock but the taller fans are definitely cheaper. If I can achieve the same result for less, I'm all for it

When you say taller, you mean the fan motor height, how far the fan motor goes into the engine?

Correct. Obviously the radiator dictates the other dimensions. I suppose "depth" would be the proper term though

I still have room with the “taller/more depth” fans, meaning I believe there’s more rom to fit an even larger fan. I didn’t go any bigger because then I’d need a different shroud or modify this one and would definitely need the a larger fuse relay kit. I’ll try to remember and take a picture tomorrow. On the passenger side I had to modify my initial radiator hose because it was on the way.

That was the only place I saw that might interfere. I went full AN hoses so I'm not sure what I can do if it doesn't fit...

@ILLSMOQ also has AN hoses, so his setup might be a good example for yours. He has a few pictures of it I'm sure.
