Is low the new rotated?

[Gripless]

Pro's

Less heat loss

less pipe total for exhaust and intercooler

Longer straight from turbo

option to make heaps of room moving radiator

cooler and more airflow over turbo itself

 

Con's

custom pipes required

new radiator and intercooler

rotated intake preferred

oil lines

Not the norm

 

Massively annoying Cons

Oil feed and lines

return system since likely below the oil level in the sump (see box for brz below)

possible dry sumping

 

 

Tuspeed low mount turbo pipe kit.

ok o it costs way to much but otherwise all the goodness.

GTX35's, GTX40's and EFR8374

 

 

 

AVO BRZ unequal length option for that rumble everyone loves.

Just as an example as guess FA has different spacing on manifold. Does anyone know if the FA is that different, i.e. Can you just use the current sti headers.

There’s a few Aussie Legacy’s running them, heaps of work to get it fitting snuggly.

Looking at the small print for that Tuspeed one it needs the Processwest V mount intercooler which won’t come cheap, on top of an already hideously expensive setup.

There was actually a US guy doing pretty well at sorting his own but gave up due to cost sadly.

Are BRZ’s further back and lower or just lower?

Yeah I read the process west bit, but I don't think you have to use them just its the easiest option.

 

wow he went to town on that collector, not sure why he is crossing the headers over.

i like the twin scroll cut off plate from the supra guy, but I've think they have it a little wrong.

 

I'd have it hinged one side and mounted in the center of the twin scroll flange so when:

open it allows the second scroll and separates the two halves of the manifold so the flow isn't messed up like adding the plate to a single scroll flange.

closed it stops the second scroll, but opens a path for the two halves of the headers to flow through the one side.

Can't spell

I don't think  "cons: oil lines" really does justice to what's required to make a low mount turbo not S*** oil through the seals constantly.

Yeah that little box kinda give away the extent they had to go through for the brz.

 

I'll fix the first post for you...

fixed 

 

still not not sure it put off the idea, yet.
