I wanted to gather all these posts and pictures together for some time and compile a journal so they would all be in one place and easy to find.

A little bit of history - I usually do the work myself on my own projects and below are two examples.

This is a street Mustang that ran 8.66 at 162mph and it was powered by a stroked 5.0 liter and Vortech supercharger. It was truly a street car - I campaigned it in the True Street class where the rules required you to drive 50 miles and then make 3 back-to-back passes, who ever had the fastest average of the 3 passes was the winner. The rules only allowed for a rear tire change after the 50 mile trip - no changes to anything else; no adding fuel, no raising the hood, no cooling down, etc. I was the True Street National Champion for 3 consecutive years in the mid 1990's with it. I also won a few Fun Ford Street Outlaw races and a couple of the Muscle Mustangs Magazine Shootouts during that time.


The 1989 Ford Mustang LX:






I was burnt out after spending 4 years criss-crossing the states while racing the Mustang, so I sold it along with my Saleen Mustang, and bought an S10. I swore to myself that I wouldn't modify the S10, but after about 6 months, I started swapping out the 4.3 liter V6 for a 5.7 liter LT4 V8 from a Corvette. The LT4 was modified with the usual hot rod gadgets - ported heads, bigger valves, cam, etc. The truck was great fun and I ending up running 11.50's with it while hazing the rear tires the entire quarter mile.


The 1999 Chevrolet S10 Xtreme:








I sold the S10 because it basically stayed in the garage - the last year I had it I only put 700 miles on it.

Well, at least for me, the combination of the Ohlins fixed perch struts and STi JDM Pink springs is absolutely perfect.

I drove on the stock set up for a little over 4000 miles before the legendary STi 'bobble head' syndrome irritated me enough to make some changes. I changed all the strut mounts to STi Group N hardened mounts and changed the stock springs to Tein H-Techs.

It was a nice setup and I put a little under 27000 miles on it, but the 'bobble head' monster would rear it's ugly head once in a while on certain roads and drive my crazy.

It took me a few months to convince myself to spend the money for the Ohlins struts. They are expensive, but they have 25 adjustments for bump and rebound together, plus they are rebuildable. So I put in the Ohlins struts and STi JDM Pink springs along with a pair of RCE Camber Plates in the front.

After getting everything in and setting the struts at 10 clicks from full soft, I took the car for a ride and all I could say was 'WOW'! It is a totally different car. I really expected it be a harsher ride switching to the stiffer Pink springs, but it was BMW type smooth. In fact, it was a little too smooth for my tastes, so I cranked the struts up another 10 clicks. That was just a bit too harsh, but the car handled like it was on rails. So I turned the struts down 3 clicks and it's perfect, for me.

I have put a little over 1000 miles on this setup and I have zero suspension noise, even with all the hardened and solid mounting points throughout the suspension (BTW: my stock struts never had the 'clunk' problem either). The struts can be easily adjusted by reaching under the car and turning the knob, the car doesn't need to be lifted at all. And the 'bobble head' is completely gone!

This is my daily driver with a nice conservative tune from MZM Performance (Austin, TX). I drive over 100 miles everyday back and forth to work. The car is absolutely wonderful to drive around with almost instant boost. So, I wanted to know what the car would do in the same form it's driven in every day.

The APS DR725 FMIC is probably too much intercooler for the 20G and the car actually made 20 ft/lbs more torque previously with a APS DR500 FMIC. But the DR500 was injured and is now on the permanently disabled list.

Drove 35 miles to the track, went through tech and spent about 5 minutes in the staging lanes before making a pass. Zero race prep done, nothing removed, nothing changed, no cool down, no tire pressure change etc. Launched easy, no clutch dumping or riding the clutch.

Track Conditions: 86F / 83% humidity / 7mph headwind
Car weight: 3565 with driver and half a tank of 93 octane pump gas

The car is a 2004 STi
Front seats are 2004 stock STi seats with a Katzkin leather kit.
Rear seats are 2006 stock WRX seats with a Katzkin leather kit.
Carpet is 2006 stock WRX
Door panels are 2006 stock WRX Limited leather
Steering wheel/air bag/shifter knob are 2006 stock STi
Center console is 2006 stock STi
Shifter trim is STi S204 "type"
Leather boots are from Redline Automotive
And everything works

Thanks to Jamie from SubaruGenuineParts.com for her help!


--- 2004 STi to 2006 STi/WRX interior swap---

Cliff notes on the install (from memory):

Re-use all of the 2004 switches except the mirror control

Use 2005/2006 brackets on everything except the rear console mount

Steering wheel and air bag:
- direct swap
- electrical connections are plug and play

WRX rear seats:
- direct swap

Front door panels:
- use 2005/2006 handle brackets
- use 2005/2006 mirror control
- move tweeter mount and rotate
- trim tab on passenger side window/lock switch
- electrical connections are plug and play, except
- mirror control wiring needs to be run from console to drivers door

Rear door panels:
- use 2005/2006 handle brackets
- move rear screw/clip mount
- trim tab on window switches
- electrical connections are plug and play

Console:
- use 2005/2006 brackets, except
- use 2004 rear bracket and grind to clear the parking brake cable
- small notch to fit the 2004 DCCD roller switch
- electrical connections are plug and play

Climate controls:
- direct swap
- electrical connections are plug and play

Price:
- depends on how much you swap, trade, sell, and spend on new parts

I'm sure I left something out, but that's pretty much it.

Note: This is a STi to STi conversion, a WRX will probably have differences that I'm not aware of (climate control, cruise control, etc).

(July 24, 2006)

I've been waiting to post these dyno charts because I wanted to go to the track so there would be ET/MPH numbers to go along with the dyno numbers, but work has owned me lately. I'm starting a new project which will own me again for another 6-8 weeks, so going to the track just isn't going to happen, for quite a while.

This is my 2004 STi daily driver and I travel over 100 miles a day going back and forth to work. I previously had a Deadbolt TD06H-20G installed and ran a 12.4 ET at 111 MPH without pushing the car too hard.

The TD06H-20G was really sweet and the car should have come stock with a turbo along those lines. But, as always ends up happening, I wanted more.

I decided to go with an APS SR55 hoping that I would gain some nice top end power and not lose too much low end grunt.

The car made some real nice power with the SR55 and is an absolute blast to drive on the street. It idles super smooth and is averaging about 24-25 miles per gallon driving back and forth to work.

On the drive home from MZM, I was thinking that the SR55 didn't feel laggy at all, like I thought it would. So I asked the guys at MZM to send my printout of the my SR55 vs my TD06H-20G. I thought it was interesting to see that both turbo's are making almost the identical power down low and then the SR55 just pulls away at about 4000 RPM (see second chart below).


Modifications:
APS 3inch Turbo Back Exhaust
APS 70mm Cold Air Intake
APS DR725 Front Mount Intercooler
APS SR55 Turbo
APS TGV Deletes
APS Turbo Inlet
Denso IKH24 Spark Plugs
HKS DLI Ignition Amplifier
MZM 720cc Fuel Injectors
MZM Tuned Ecutek Reflash
Turbo XS DTEC Boost Controller
And quite a few parts coated and/or ported by Crucial Racing.


All tuning done with 93octane fuel. Stock STi's usually put down about 200-205whp on this particular dyno.

--- SR55 vs TD06H-20G: ---

The black leather Recaro Sports are now installed. Of course, my lack of camera skills don't do them justice.

Thanks to Nick at Speedware Motorsports for the deal on the Recaros!

I just don't have the free time like I used to, so over the course of those 2 years I had developed a level of trust with Chris and Kenny at Gillman Subaru North in Houston and with the guys at MZM in Austin, to do the things I didn't have time to do or just didn't feel like doing myself.

Both the TD06H-20G and the APS SR55 had been tuned by the guys at MZM, so after visting the shop one day, I ordered a complete Cosworth setup from MZM and spent time there last October while we installed everything.

For better fuel and timing control, a HKS F-Con V Pro was installed while doing the engine swap, in preparation for the new fuel injectors and turbo that would be installed in the near future.

I drove the car when I had a chance and finally got the new engine broken-in at the end of January. By this time I had complete trust in MZM, so I dropped off the car and to let them finish up everything.

Anyway, enough with the talk and on with the pics!

Tial 44mm wastegate and APS dump-to-atmosphere tube:








I knew I wouldn't like the dump-to-atmosphere configuration for driving around, so the guys at MZM put together a second down-pipe with the wastegate routed back in to the exhaust. That way I can run the dump-to-atmosphere setup when needed for all out performance and swap to the routed-back setup when the noise isn't wanted.


Custom routing of the wastegate back in to the APS 3.5in exhaust:

The last pics are of the car near completion and strapped to the dyno getting the initial parameters configured. It idles amzingly smooth with the cams and 1000cc injectors. We are now waiting on the down-pipes to return from Jet-Hot and the real tuning will begin.

A small little update. Well, it seems the car is making a bit of power - and with that, a portion of the drivetrain decided to let it's voice be heard and protested profusely.

Here's the transmission output shaft, or at least half of it. It sheared clean in two, right at the driveshaft yoke:






And this is what the shaft is supposed to look like:

Built and tuned by MZM Performance (Austin, TX)


A few weeks ago, it sheared the transmission output shaft in two, so this run was done with all the electronic helpers turned off - no launch control, no anti-lag, no flat foot shifting. I wanted to know what MPH it would run, so I just slipped the clutch on the launch and rolled in to the throttle.

I don't have any dyno print outs to scan/post. The dyno's hard drive bit the big one and all the runs were lost. It put out 434whp on MZM's Mustang dyno - stock STi's usually do around 205whp on it.

The final tune is in the car and it's ready to rock. I just have to wait for decent weather and time in my schedule to make it to the track. Until then, the dyno graph will have to do.

Dyno graph -




Some interesting points that will hopefully answer questions before they're asked -

* MZM's dyno is a true heartbreaker and reads very low. Do I care? Heck no, the car consistently runs great numbers at the track and it's MPH is a true indicator of the real power it's making. We'll see exactly what it runs as soon as the weather and my schedule permit.

* For people that like to play the numbers game, Mohammad mentioned that a typical DynoJet reads 20% higher than his Mustang dyno, so that 540whp would be 648whp.

* The car has already ran an 11.33 at 127.92mph a 434whp tune. It's going to be real interesting to see what the car runs with an additional 100 horsepower and not having to short shift at 7000rpm.

* Fuel used was Phillips TrackTek 105 octane unleaded, no alcohol, no methanol, no water, etc - just motor and turbo.

* Temperature was 94 degrees and humidity was 95%.

* This car peaked at 205whp stock on this dyno (at 6000rpm, if I remember correctly) - it's now making that much power at around 3300-3400rpm.


Major components of the car -

* APS TSR70 turbo
* APS 3.5 inch exhaust
* APS DR725 front mount intercooler
* Cosworth block, heads, cams
* HKS 1000cc fuel injectors
* HKS F-Con V Pro engine management
* MZM awesome tune

I knew that I was going to get kicked off the track for running under 11.50 if I ran the car full out, so I made three or four 1/8 mile passes getting the launch and shift points down.

I bumped the launch control up 500rpm each time and after doing a 1.5 sixty foot when leaving at 5500rpm, I felt that was as good as it was going to get. The 1/8 mile times and speed showed that the car was capable of a 10 second pass, I just needed to put it all together on a clean pass.

So I let the car cool down for about an hour and lined up for the final pass. It launched beautifully and I flat-footed every shift and ran it out the back door.

Of course I was lectured at the time slip booth and was told to go see the track manager, but I couldn't find him (wink wink nudge nudge) and just proceeded to drive out the gate.

A couple of under hood shots. Your typical crowded Subaru engine bay.

Dasani's Super Sleeper Sti Slugger, Top Scoob 005

See original thread here: http://forums.nasioc.com/forums/show....php?t=1453087

Someone asked me to post this up... I'm terrible at tooting my own horn, but here it goes...

A bit of history - I usually do the work myself on my own projects and couple examples are below.

The first is a very streetable 1989 Ford Mustang that ran 8.66 at 162mph and was powered by a stroked 5.0 liter and Vortech supercharger. It was truly a street car - I campaigned it in the True Street class where the rules required you to drive 50 miles and then make 3 back-to-back passes, who ever had the fastest average of the 3 passes was the winner. The rules only allowed for a rear tire change after the 50 mile trip - no changes to anything else; no adding fuel, no raising the hood, no cooling down, etc. I was the True Street National Champion for 3 consecutive years in the mid 1990's with it. I also won a few Fun Ford Street Outlaw races and a couple of the Muscle Mustangs Magazine Shootouts during that time.

I was burnt out after spending 4 years criss-crossing the states while racing the Mustang, so I sold it along with my Saleen Mustang, and bought an 1999 Chevrolet S10 Xtreme. I swore to myself that I wouldn't modify the S10, but after about 6 months, I started swapping out the 4.3 liter V6 for a 5.7 liter LT4 V8 from a Corvette. The LT4 was modified with the usual hot rod gadgets - ported heads, bigger valves, cam, etc. The truck was great fun and I ending up running 11.50's with it while hazing the rear tires the entire quarter mile.

I sold the S10 because it basically stayed in the garage - the last year I had it I only put 700 miles on it.

I really don't know how I ended up with a Subaru after that - I guess I was just looking for something different. During the first 2 years of owning the STi, the VF39 was swapped for a TD06H-20G and then the 20G was swapped for a APS SR55. The car ended up running 11.50's at 122mph with the SR55.

In May of 2006 I did a complete black WRX Limited interior swap and updated the steering wheel and console to 2006 STi pieces. I installed a complete set of Defi gauges, along with a few other things. In November of 2006 the leather WRX seats were removed and new black leather Recaro Sports took their place. At that point the interior was pretty much complete and the itch for more power was really getting bad.

I just don't have the free time like I used to, so over the course of those 2 years I had developed a level of trust with Chris and Kenny at Gillman Subaru North in Houston and with the guys at MZM in Austin, to do the things I didn't have time to do or just didn't feel like doing myself.

Both the TD06H-20G and the APS SR55 had been tuned by the guys at MZM, so after visting the shop one day, I ordered a complete Cosworth setup from MZM and spent time there in October of 2006 while we installed everything.

For better fuel and timing control, a HKS F-Con V Pro was installed while doing the engine swap, in preparation for the new fuel injectors and turbo that would be installed in the near future.

I drove the car when I had a chance and finally got the new engine broken-in at the end of January 2007. By this time I had complete trust in MZM, so I dropped off the car and to let them finish up everything.

The car was back to together, buttoned up and put on the dyno. We discovered that there was excessive pre-turbo back pressure and we had to wait for a new turbine housing to arrive, so the car wasn't tuned to it's full potential. In the meantime I was curious to see what the car would run and it put down a respectable 11.33 at 127.92mph. While waiting for the new exhaust housing to arrive, D-Sport magazine did a feature on the car that appeared in October 2007 - they nicknamed the car "Silver Sleeper" and the name just kind of stuck.

The new turbine housing finally arrived and really allowed the car to breathe. MZM swapped the housings and strapped the car to the dyno once again. This time it made 540whp at 27psi. With everything finally in place, the car ran a 10.57 at 134.72mph and all was good. For now.

As these pics prove, I suck at photography and it has never been the camera's fault.

This is the car in the exact same state it was in when it ran the 10.5 second quarter mile pass. I drove to the track, made the passes, and drove it home.
