I'd love to know your thoughts on three suppliers I'm looking at for potential cooling system overhaul kits: ecstuning, bimmerworld, turner motorsport. They each have kits that are fairly similar to each other, and all allow me to upgrade to a Stewart high-flo pump. I'm looking at the non-BMW ecs kit because, wow, all BMW original parts are way more expensive! I am assuming that both the BW and TMS kits are non-BMW OE kits, though I'm having a hard time determining for sure.
So... any pros/cons in comparing these 3 vendors for these parts?
Did you guys include radiators in yours? I may just bite the bullet and upgrade to a full aluminum take like I have in my track car. But I was surprised to see the ecs II kit leave it out. Thought?
I noticed that the kits only contain radiator hoses, not expansion tank or heater hoses (5 smaller hoses total I think). Are these smaller hoses failure risks, too?
My car is an '05 manual with 97k miles.
