Wizard’s 3.4L 825hp Twin Turbo Supra Build
EDIT: Dyno vid now posted on page 7!! 1/7/10
EDIT: Dyno graphs now posted on page 5!! 11/12/09
Just thought I would share my Supra build which is moving along rather swiftly at SP Engineering, here in sunny California.
Background info:
About 7 years ago I was in the market for a sports car as my current car (a 92 Chevy Camaro RS automatic) wasn’t fulfilling my need for speed. I contemplated putting a custom turbo kit on it, and even checked out one shop for a quote, but ultimately decided against it. I decided it was time for a new car and so the research began.. J At that time, I was deciding between a 6spd Twin Turbo Supra, the RX-7, the mighty 300zx Twin Turbo, and Mitsubishi’s 3000GT. After my research, it was pretty clear to me that only a Twin Turbo 6spd Supra would meet my current need for speed and my ultimate power goal to be met a very long time in the future (now).
I joined Supraforums back in 2002 and started looking for a Supra to buy; and looked at Autotrader as well. I found my current Supra within one month’s time I believe. Most wait many, many months, sometimes years to find the perfect Supra which meets one’s needs/budget, but I guess I was extremely lucky. I spoke to the owner of the Supra on a Friday and drilled him with questions because he lived in San Francisco and I lived in San Diego at the time. That very same night, I decided I was going to check it out and purchase it if everything checked out. At midnight my good friend Josh (Ptatohed) and I started our adventure (with no sleep) and drove 9 straight hours to San Francisco to see/purchase the car. Luckily, the car was in pristine condition and matched the description by the owner and looked just as good in person as it did in pictures. The next 4 hours were spent dealing with paperwork and such since he had a lien on the Supra. I then drove the Supra back 9 hours home. It turned about to be an exact 24 hour adventure as we arrived home at midnight!! At first, I thought I kind of rushed my purchase because I bought the first Supra I checked out, but in hindsight I’m glad I bought it. It was a low mileage (29k) TT 6spd that was practically bone stock (only had an ebay strut tower bar and some no name catback on it). Over the years, I’ve come to see that low mileage bone stock Supras are pretty hard to come by (even harder now I’m sure).
Here’s my mod list before it went under the knife:
Engine/Intake/Exhaust:
Rod Millen downpipe
Unknown aftermarket exhaust (already on Supra when I bought it)
HKS SSQV BOV (OEM location)
Max Air Box with K&N filter
Greddy oil filter relocation kit
Various TTC dress up items

Fluidyne Radiator
Greddy 3 row intercooler
Powerhouse Racing polished upper radiator pipe

The best the Supra ever dynoed was 383hp/323TQ at 18psi when DynoXtreme in Stanton California had a dyno day for locals. Note: Supra dynoed only 2 more HP than my Maxima at same place.

Special thanks goes to…
SP Engineering (SPE). Before I get into my story/build, I would like to acknowledge and thank the guys at SP Engineering. First, they are always available to take my calls and answer my questions. Eugene (head of sales and service) always keeps me up to date via email/phone and sends me pics of the progress constantly, which you’ll see below. He also fields my numerous questions, and makes sure all my requests regarding the build get taken care of. When I’m at the shop, I also work with Alex (the big boss man), who is always friendly and eager to answer my questions as well. The techs are great too; always willing to explain why they did what they did; and field my numerous tech questions. Their craftsmanship skills are unreal, and they never cut corners to save time. Mechanical, electrical, welding, custom fabrication… you name it…..these guys are masters at what they do and take pride in their work. The guys at SPE also provided a lot of the parts you see; and at excellent prices as well.
You know how some shops/companies are nice and helpful up front, but once they have your money, their attitude/customer service changes for the worse?? Well, SPE’s attitude/customer service has been top notch from the very first time I met them to discuss my build, all the way up through today. I couldn’t be happier with how this build is going.
Truth be told, I’ve been putting off this build for years because of two reasons: 1) I’m pretty picky when it comes to my cars and I have a hard time trusting shops based on past personal experiences, and all the horror stories I’ve read online. 2) My build would not be complete without the coveted Veilside intake manifold. After quit of bit of research, it was a pretty clear choice…..that if I was going to pull the trigger and do a build of this magnitude only 1 shop would do, and that’s SP Engineering. SPE has made this build rather headache-free and quit enjoyable. As for the manifold, I was lucky enough to track one down about 1 year ago IIRC.
I believe one Supra enthusiast shipped his Supra from Hawaii to California to have it built by SP Engineering. Only know do I understand why one who go through the hassle/expense of shipping a car across the Pacific Ocean.
Thanks for looking. Pics to follow.

I have to admit that when I first saw this pic, I was a little sick to my stomach. Up until now, I've done nothing but simple bolt-ons and nothing of this magnitude. But I knew I was in good hands with SPE.

Looks pretty incredible. The owner of the shop that I get my cars dynoed at used to have an 800hp Supra. I say used to because he lost control of it and wrapped it around a tree. Those cars with that much hp are frighteningly fast, even for the driver. Enjoy it, and be careful! I look forward to seeing more pictures.
Can't wait to see it finished!

Yup. SPE works on lots of Lambo's, GTR's, you name it.
Thanks Tiger.
I usually go to Supra Invade Las Vegas every October. Missed this year cuz my build was done. Hopefully next year.

Not sure, but i do know the guys here in Austin lay claim to having the fastest street legal Supra in the states, it put down right under 1300hp...
http://www.youtube.com/watch?v=nJN7A...eature=related
Ran the Texas mile with a top speed of 246.2
http://www.youtube.com/watch?v=8xr58Fq9fwo
I had these guys tune my maxima earlier this month. Their shop had some really sick rides. some nice Supras, built Porches and one of the guys that works there drives a mean @ss Z31 with a 2jz swap...

damn, that is a sweet ride to have. The mark-ups for used supras used to be insane(not sure nowadays) because of their rarity, and popularity. I have always wanted one, but it was always out of my price range. You going to drive this, or the max to the minimeet on the 17th?
