GRD Tuning: Legacy Spec B Tune w/Prototype APS parts

GRD Tuning · 04-15-2009, 05:57 PM

We had sent out our customer's 2007 Legacy Spec B to APS in Australia in order for them to develop parts. The car came back transformed with a number of prototype APS parts (list is below). He realizes that the hi-flow cat is a slight limiting factor on power.

- APS 3 Inch Turbo Back Dual Exhaust
- APS High Flow Cat
- APS Turbo Inlet Pipe
- APS Cold Air Intake
- APS Fuel Rails
- APS Front Mount Intercooler (Stealth Black)
- Cobb Accessport V2 (Tuned By GRD)
- Walbro Fuel Pump GRD Custom Setup
- Deatschwerks 850cc Injectors
- TurboSmart Dual Port Blow Off Valve
- NGK Iridium One Step Colder Plugs

The thin plot on the dyno chart below are pulls with the stock Spec B before we sent it to aps, on our dyno (dynapack). The solid line is the Spec B tuned by GRD using an Accessport with the APS parts.

Stock Pulls: ~205whp & 240 wtq

GRD tune w/APS mods (stock turbo): ~265whp & 335 wtq

The customer wanted more power so he decided to go with an APS sr-40 turbo with a forge actuator. The thin plot is a 93oct tune at 21psi tapering to 20psi by redline. The solid plot is 100oct mix (1/4 tank of 93 oct) at 23psi tapering to 20psi by redline.

APS sr-40, 93 octane tune: ~356whp & 353 wtq

APS sr-40, 93oct/100 oct mix: ~388 whp & 398 wtq

Stay tuned as the customer said he is thinking about going bigger

the customer had his car sent all the way to Australia from California????

How long did this process take from start to finish??

GRD Tuning · 04-15-2009, 09:18 PM

It was sent out of chicago-cali-australia. If i remember correctly it was gone 12-15 months, and a good portion of that was transit time. It is not the customer's primary form of transportation which is why he was ok with it being gone.

Got pics of the parts? I'm especially curious about the CAI and the FMIC.

How much boost were you running with the stock turbo?

Thanks!

Irishman · 04-16-2009, 12:26 AM

any pics?

camber · 04-16-2009, 01:01 AM

+1 for pics...

Interested in FMIC setup.

DoctorNick · 04-16-2009, 10:16 AM

Why the dip around 4200. Looks like det.

benw · 04-16-2009, 11:10 AM

I wish we had APS parts when we built our customer's 08 Spec.B (featured in the most recent Drive Performance Magazine). We had to take a Perrin FMIC for LGT and custom make the piping, along with a full custom Tial 44 recirculated EWG setup.

GRD Tuning · 04-16-2009, 01:00 PM

I lost the pics i had of the car but i'm working on getting more.

Both of the GRD tuned maps have dips in them near that RPM.

GRD Tuning · 04-16-2009, 01:36 PM

The dip you are referring to is not detonation. Per my conversation with our tuner this is a trait we have seen on a number of legacies. Cam timing does not follow through which caused the slight dip. We have driven the car on the street and spoken to the owner of the car, and this in no way affects drivability.

I am interested in your decision to go with a Forge actuator (I also run an APS SR40). Also, could you share the Forge part number that will mate up with the SR40?

Thanks.

GRD Tuning · 04-16-2009, 10:21 PM

I will check the part number when i'm back at the shop tomorrow and i will get back to you

GRD Tuning · 04-17-2009, 02:40 PM

Hi,

We went with the forge actuator b/c of the ability to run higher boost. I haven't been able to find the part # but will PM you if i do.

Furious George · 04-17-2009, 04:51 PM

Thanks. The reason I ask is that I am having trouble hitting my target boost recently (22 psi), and I have some reasons to think that the WG may have something to do with that. If you can find it, great, if not, I am sure I can talk to the people at Forge for help.

unclemat · 04-17-2009, 08:08 PM

Seriously? You sent a car to Oz, to have few simple mods developed? Who paid for it I wonder...

Aussie Legacy btw has been 2.5L since at least 06 if not 05 (first or two years their cars were 2.0L like JDM). Pretty much same car except bumper differences (and RHD).

DoctorNick · 04-17-2009, 10:02 PM

The shop the car was tuned at doesn't have any fabrication abilities. Its a bolt on type place. I'm sure that was part of the reason.

GRD Tuning · 04-18-2009, 11:16 PM

We sent the car out per APS' request since we are a distributor for their products. The request for the car was done b/c not many vendors had parts available at the time for the car.

Also, we do have the ability to do custom work. Our decision to send the car car was solely based on a request that was sent our way. Thank you for your continued positive contribution to this thread.

APS Legacy? i like it.

Sideways76 · 05-01-2009, 07:58 PM

Subscribed. I'm currently looking at turbo/fuel system upgrades for my Spec B.

GRD Tuning · 05-01-2009, 11:40 PM

We followed up with the customer and he is enjoying the car. However, he took a test drive in another customer's sti with an aps tsr-70 kit, and now wants to go bigger

DoctorNick · 05-02-2009, 09:52 AM

Will the TSR kit bolt on or will you be sending the car back to Australia to get that kit fitted?
