Cost, and it's not necessary for a stock vehicle.

Neither of the options you are looking at require the brz pipe.

If going with a new pipe, much easier to cut the mentioned pipe and bead form it, done, no more kinks and cheaper too.

Couldn't you just use a longer section of hose and zip-tie it somewhere to prevent it from kinking?

A picture would be nice to show what you mean... after seeing Kostamojen idea, I may not get the BRZ pipe and just get the rest and wait and see how to plumb the oil cooler.

In the picture where you have the "outlet?", it's the bend pipe right next to it and points to fig 72.

Therefore, cut + bead form = no more bend = no more kinks when using original frs/brz hose.

Subscrizzled my nizzle.

Here's a pic I took just now from the topside of the engine, you can see how slightly bent the BRZ hose is when installed on the FXT pipe.

I have no worries about the long-term effects of this as the kink is very very small. I could bend the FXT pipe upward some and completely eliminate it, but like I said, no worries.

Depending on how large that pipe is, i'm going to use my hand pipe bender to straighten that part out if I can. if not, no biggie.

FWIW that part from my dealer is 76.20...so it adds a bit to the total and puts the cost closer to $350.

If you order it from heuberger its cheaper. I posted their prices for everything in a screenshot above.

$260 and change for everything

Running it this way seems a lot simpler.

I was considering that way at first as well, my only concern was if it would possibly cause a hinderance in coolant flow.

The oil cooler inlet is the same size, but the outlet is smaller. Also, all the other coolers are plumbed in with extra piping/lines, maybe Subaru thinks there wouldn't be enough coolant flow to run everything through the cooler instead of each having their own coolant feed.

All speculation, but thats why I ended up buying the pipe and adding the fitting to get the coolant from an additional spot for the cooler.

FYI that was just an early idea. I ruled it out because the heater hose is much larger than the oil cooler lines.

There is another option other than the FXT return hose for manual transmission cars, and that is the coolant crossover pipe on top of the engine that has a blocking plate that can be replaced with a plate with a fitting from the AT cars so you can run the return line directly to there. It might be cheaper, don't know.

Noted. Well it was too simple to be true. Haha.
