Well here it is. I've been running through a bunch of setups and this is hitting the end of the straw.

warning to a few, this is overkill for most of you. most people can do fine with a stock radiator and one puller (all i could fit)

my engine is sitting forward like anyone using the r33 crossmember

i cut the support a bit. the pulley has rubbed a bit on the heat protection shield on the flex. but the brackets i made for the radiator arent tight enough. so thatll be a fixed problem soon.

as for performance. i really wont be able to test this to the full extent till the desert heat picks up and i get back on the bigger tracks we have here in town.

im goining to get a thermo switch soon because i cant get the car to operating temps in arizona's 70-80 degree winter weather.

You can also gain a small amount of clearance by removing the plate on the back of the fan that says FAL. You have to pull the fan out, but it only takes a few minutes and gives you about half an inch clearance. I had them that way when I had the stock radiator and dual pullers.

I took off the rubber around the felxi's on mine. Didn't think to take of the back plate. The PS might fit if I do.

I removed the plate and had just enough room to fit the RB radiator and FAL 220's with about an 1/8th inch of clearance between the fan and pulley
