Accelerated Performance 2013 BRZ - FRS Turbo Kit Designing

[Coheed]

The disco potato will support around 340whp when pushed to the limits on the .86ar housing. The smooth stainless housing will help a bit in reaching that goal. I don't see this car hitting that number without a compression ratio drop to help manage cylinder pressures a bit better though.

I can see 300whp coming though. Should make it there on 10-12psi. But stock internals will be put to question in this range of boost as well. 8psi may very well be the limit, but we won't know for a little while.

This setup seems well-thought. Room to grow. The disco is the best street turbo for a 2.0. They are really responsive and make great power. Next step up imho is the GT3071r.

If the disco potato can already put out more than this motor can safely handle then I'm guessing that a 3071 would be complete overkill for the stock block...probably doable on a built motor though.

What about smaller turbos like the 26xx series?

[TSLRich]

love the disco... it is so responsive.

Cannot wait to see WOT video! All the best with the tuning.

they are already making great numbers on this turbo with only 4psi adding the amazing gulp of power down low in the RPM range they are able to make. yea a smaller turbo would give you even quicker spool at an even lower RPM range but to make the same power this turbo currently makes with a smaller turbo you would need more boost and more boost creates more heat. yea you have an intercooler to help but now the system has to work that much harder to keep everything efficient. and another key factor is how high this engine is able to rev, the smaller turbo might not have enough flow to keep that power strong toward redline, it would die off in power prematurely =) plus you always wanna make boost as efficiently as possible which is why turbo selection for your application is most important and i think this turbo is the perfect size for this motor and the boost they are going toward.

Again I am comparing to the sucessful $3k flying miata kit which has a great rep for a mild boost DD (majority of buyers.) I personally would not want to DD an FR-S with 300+ rwp HP.

But it is very promising the performance gains with only 4psi boost, either that is a very efficient turbo/intercooler or its the boxers high compression ratio?

IMHO this is similar to the 90's, back then any quality engine management upgrade either to the stock ecu or standalone was a very expensive endeavor with very few knowledgeable folks who could tune a turbo fuel injected engine, most couldn't change the timing at all, this new DI learning curve and the single source supplier is a bit like re-living that.

If the FR-S continues to sell, there will be more competition on the tuning end and more balanced to daily driver turbo kits.

I think a lot reading this thread want a modest boost in horsepower and torque not a dragster, JMHO.

1. Basic Flyin' miata kits use cast manis
2. Don doesn't plan on this being a 4 psi kit, he is aiming for final numbers at 6-8psi
3. Miatas have a lot higher production number therefor a lot more sales in the aftermarket industry. Flyin' Miata didn't even come around until there were 1m+ miatas on the road

I can probably speak for a lot of people when I say I'd rather spend more money up front on good, quality, reliable parts instead of cheaper one that will save me money upfront, but just cost me more in the long run (time & money). Also, Don has put a lot of time, effort and money into this so he deserves to be paid.

I deal with this everyday for the last 10 + years when people compare buying a Corolla/Camry to Focus/Fusion or Cobalt/Cruze/Malibu, etc. Like the old saying goes, "You get what you pay for."

To me, I think this kit would be perfect. I'm not looking for crazy power. 250whp would be such a blast in this car! I mean, look how much fun this car is putting down 160-170whp?!? I/H/E/Turbo & Tune and I'm set!

I wish I had the money to jump on this right away, but I spent a lot on my trail rig and still haven't installed those parts yet so I need to get one project finished first.

Why is everyone calling the turbo, disco potatoes? It is much longer to type out.

i have no idea but until now i dident know what a disco potato was.

[Don@Accelerated]

BRZ off to the 1320'. Come see it at Milan Dragway if your interested!

Disco Potato is a nickname for the GT2860RS....Nothing more than a nickname!

Be sure to let us know what it runs.

[merlin2111]

I am guessing 13.9.

Sounds about right--13.7-14.0 range.

[Visconti]

lol - that poor car

[Silverdub]

Im not sure if its been said before but when are do you plan to g2g again for more tuning?

I love it! Can't wait to see the time slip.

[dwx]

I'm going to guess it will run 14.0.

If I remember correctly, it was the first car (modified 240sx?) to run this hot-side/cold-side combo that was called the Disco Potato due to it's paintjob that I believe was a mix of brown and Mystic. The turbo setup worked so well that other people wanted the same thing and it was easier just to refer to the turbo as the Disco Potato.

But it's been a long time since I was familiar with the potato's origins, so I could be (and likely am) wrong on some points.

That'll do me for a guess as well. Some testing of the clutch on this exercise too

Sentra SE-R, I think?

You're right.
