Smile My STi is nearing completion (lots of pics & a bit of pre-STi history)

A few weeks ago when I was selling a lot of parts, some people asked what was going on with the car. I explained that I was changing/upgrading things and promised to put together something when it was near completion. Well that day is near...

First 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.

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.

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 guys at MZM were nice enough to stay late on a Saturday and help me install a different hood and trunk.

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.

Very nice. What are your overall goals? Are you wanting more of a 1/4 mile car?
Interested in how you like the Driveshaft. Cannot find it now, but thought the max speed recommended on the driveshaft was a limiting factor.

No set goals with this one, just a nice all around car.

I've used ACPT driveshafts in other projects before - my Mustang had one and it was a bit over 1200 horsepower. The pro-mod guys use them and they run 6 second ETs at over 230mph.

Kewl. Couldn't find the restriction, so I'm probably wrong. Nicely done with top quality parts.

Can't wait to see the numbers!
