Default MAPerformance Boosted FRS

Hey guys! I am a sales rep with MAPerformance, and I thought I would share my FRS project with you. We are currently using it to develop products for the FRS/BRZ platform, and so far its been lots of fun.

Purchased it in June of 2013:



Then started with some N/A mods:

aFe intake and Perrin pulley



Then went with a Tsudo catted front pipe and cat-back



Now it was time to optimize those mods, and started with an Ecutek tune. Here is the 93 oct tune vs bone stock



Then it was time to get rid of the skinny stock wheels and tires, and I went with the Mach V Awesome's in 17x9 square set up







Next I decided to get rid of the stock header and went with a Revworks UEL header



Went back to the dyno for an E85 tune!

Drove it that way for a year and honestly, those mods made the car much more fun to drive, and really should have been that way from the factory. With that being said, I knew the FI bug would bite. That's where we are today











Currently on the stock clutch, so we are a bit limited on power. But so far with the small Precision 4854, 10.5 psi of boost on 93 octane here is where we are at. Once I get a new clutch this spring, we will turn things up

Not bad! Can't wait to see what more you have in store for the car. With that being said, on the 4854, what does the size of the turbo compare to in terms of other similar turboes?

In all honesty, this is a pretty small turbo. Specs are as followed:

MFS (Machined From Solid) 48mm inducer compressor wheel
"B" compressor cover 2.8" inlet/2.0" outlet
54mm exducer turbine wheel
Turbine housing options:
T3 .63 A/R with 4 bolt discharge

We went this route for our entry level kit for a quicker spool and modest power rating. This turbo is rated up to 360whp, so it may be maxed out on E85. But with the T3 flange, you can run any type of Precision, or Garrett style turbo.

Good choice on the 4854, I think people forget what these things can do with this amount of power, props to you for not going overkill with it. What clutch are you looking at?

Just out of curiosity why not mount the turbo lower? Would make boost come on sooner.

This make me want to sell my wrx and get a brz :P

^was thinking the same. I know nothing about this turbo other than it being smaller but it doesn't seem to spool that fast compared to other turbo BRZs running larger turbos.

Looks like a very clean setup!!

Our kit hits full boost around 4000rpm. And remember, this is a journal bearing turbo, a lot of the other kits out there are using larger BB turbo's. But spool is about the same if not better than most I have seen on the market.

Main reason is fitment, other big reason is mounting this turbo much lower would require an oil scavenging pump, and we personally didn't want to go that route.

Not sure Art what I plan on doing with the clutch. I am going to rock the stock one for the rest of the winter, but I have to see how far I plan on going with it. I thought I wouldn't want the 4854, but honestly after driving it this weekend, its plenty of power. I might run an E85 map as well. I have driven a few with the FX400, and I wasn't a big fan of it. If I keep it at this power level for a while, I may go with the ACT Street Clutch, or even the Exedy stage 1 which I heard good things about.

Quick little driving video of the set up. Still have some small work to do on the tune, but we did get the car up and running. So far so good

Sounds like a good plan, I also hear good reviews on the Exedy. You may as well upgrade, especially if your numbers are going to be going up bit by bit. I'm contemplating running E85 myself but it seems likes it's getting harder and harder to find around my area, 93 used to be a lucky find a few years ago and now its everywhere.

Ended up with a Competition Clutch stage 3 with a ceramic segmented disc. They hooked me up pretty good, so I will be testing it out shortly!

Nice to see one with a turbo. Those are very nice cars but just way to slow by themselves. Too much money though to make a slow car fast. Always easier to make a fast car faster. Good job though guys. Always impressed with your work

Competition Clutch finally came through for us with their stage 3 segmented clutch kit! Can't wait to get this on and finally dial in the tune

So we got the clutch broken in and we decided to strap it down last night to do some more testing. We are still on waste gate pressure, dialing that in first before we turn it up. I still need to attend to the vacuum hoses under the intake manifold and secure those first before we turn it up. We didn't really make more top end power, in fact, due to the 40 degree warmer weather than the previous dyno, we lost a bit up top. We were hitting around 9.2-9.8psi vs. the 10.5 the first time. Car is feeling much better, with a broader power band than before. We are either going to turn it up, or I may swap out for a 5858 next. I will get a dyno vid shortly.

Last nights run vs previous tune:
