What kind of oil temps are you observing?

The highest I've seen to date is 225 having some "fun" on back curvy roads.

I do not believe (and it has been proven from other forum members) that the Forester oil cooler setup would last a full 20-minute track session on full kill. I'm *currently* okay with this due to where *we're* at with the car, but an air to oil or a larger water to oil unit may be in the future if we want the BRZ to become a more track serious car.

Thanks,
Eric

Thank you.
Are you still running 0w20?

0w-30 Amsoil, though I'd probably be safe with 20 weight right now as I haven't seen temps over 230.

Turbo placement isn't massively important. Keeping hot, fast moving exhaust hitting the turbine is a big goal, as is ensuring that the turbo can properly drain the oil from its CHRA. Hope that helps some.

Significantly or in a neglegible way for a street car? Yes that's exactly the reason, I just want to boxer rumble on top of the performance boost.

Thanks for the reply and the explaination, that clarifies better.

Using an unequal length manifold on a twin scroll turbo just seems pointless.

I understand that... but the boxer rumble

[Tokay444]

It's not a boxer rumble. It's an unequal length manifold rumble and it's performance robbing.

I know, I know and I do understand better the impliclations now that I read more about twin scroll turbos... well, something to ponder on for sure. If anything I made up my mind about the turbo brand I would be happy to go with and those are Garret, Precision and Borg Warner because they seem to be the best one out there; now it's matter to start looking for suppliers in UK.

For those people more in tune with Facebook... I have started a Facebook group for the turbo kit .

Any issues with rain on the turbo? My hood is vented and my car is a DD. I know most things under hood aren't bothered by water

Edit, addition: the guys above were talking about the UEL vs EL headers. I know with a twin scroll turbo it's pointless. Assuming the turbo wasn't twin scroll, what kind of performance loss would you be looking at for UEL?

UEL with twin scroll

No issues, though being Arizona, it doesn't see rain THAT often. The kit is made with good materials and should not have an issue in rain or snow with hood louvers. I'm not bothered or worried about it (minus the extra dust that comes in, it's a tad annoying).

You'd still have some loss in performance, probably not significant enough to really worry about unless you're racing. I don't really like the boxer rumble, twin scroll efficiency for life !

Different turbos but same concept: http://dsportmag.com/the-tech/twin-s...-great-divide/

Here's a decent comparison from DSport as well: http://dsportmag.com/the-tech/full-r...spirated-fa20/

It's not exactly apples to apples (different dynos, different tuners, etc) and it doesn't have a boost curve on the plot, but it sure looks like the twin scroll turbo (Velox Shop Car) spools quite a bit faster than the single scroll 7163 (DSport shop car).


DSport Single Scroll V-Band 7163, stock engine, 15psi, e85


Velox Twin Scroll 7163, stock engine, 13.5-14psi, E80
