Very cool. I have always thought the turbo that European Car did a bit on in the 90s was cool. Wonder what ever happened to that one. Make a kit for the ricer crowd and you'll be able to sell enough to buy a Ferrari to use as a prototype car etc. and be able to keep it and get a vette, and a 993, and a n/a 996.......etc. etc. etc. The ricer crowd (at least in my area is not afraid to throw money at their cars.

John,
Congratulations on getting it together and making the trip. I would like to have seen the setup and shot the breeze with you.
I decided not to take the 2 extra days it would have taken me to drive back. Instead I made a loop of the 4 corners region of the US. We drove from here to Grand Canyon,
Monument Valley, Mexican Hat, Goose Necks, Valey of the Gods, Mookie Dugway,
Mule Point, Hoovenweep, Cortez, Durango, Silverton, Ouray, Telluride,
Uncompharge, Manti-La Sal, Moab, Arches, Canyonlands, Dead Horse Point,
Green River, Capitol Reef, Dixie, Grand Staircase-Escalante, Bryce Canyon,
Zion, Las Vegas, Mojave and back home. Over 2000 miles in the 928 with no traffic, no radio, no celll phone, and not a single problem with the car. Man I love these cars. First vacation I've ever really had.

Good work John!
Here in Europe, the consensus is that turbos is the most efficient way to go, compressors are "the american way"... Compressors are gaining popularity though, most popular for those seeking driveability before maximum power.
Are you willing to give more information about your setup? I understand it if you don't want to share too much...
I am wondering about your manifolds, are they very different from the Callaway ones? Did you manage to avoid cutting the shell? Where do you route the intercooler lines?
Is it possible for you to create a kit for about the same price as 928Motorsports? I guess it would be hard to do with the extra work on the manifolds?

No, not stock injectors...these are much larger. I will gladly sell you the entire setup complete with the program and custom wiring harness (that is where the severe time is involved). It would be a reasonable price. I would do this before you go ramping up that pressure to your rails. The hot wire is a custom unit with a calibration for the correct airflow for about 12 lbs of boost on the 4.5 liter engine.
Put the hot wire in front of the supercharger on the draw through side. For you guys blowing through the AFM will work, because by the time you are making any significant boost the AFM will be pegged anyway, but the MAF will give you a much better tune. Still, blowing through the AFM is not that technically correct. I don't know, maybe you guys have moved it in front of the supercharger, if so that is a better place.
If you are going cheap you could just install a much larger injector, move the AFM and tighten up the spring in it. That would get you to about 8 lbs of boost, no problem, but the MAF will still outperform any AFM setup. It is all about transient response and the MAF has it nailed down.
Lag, I was just sure you and Murf would be in Wichita...anyway, someday we will get the chance to meet up. Thanks for the compliments.
I'm still resting from the last 6 weeks of hell I put myself through to finish this car. I think I am taking the wife on a long weekend beach trip next month for her 30th B-day. She was very patient through this entire project and for that I am thankful.

There is a bit of cutting to be done, but not much at all, just one hole up by the radiator. I have a small brochure I can send out, but maybe I should get some pictures on here first.
The manifolds are quite different than on the Callaway, specifically the driver's side. It is a two piece design to snake around the steering shaft. You would have to see it, too hard to describe...
I need a better trans now so I can really enjoy this car. I got one good 1st-2nd shift this AM...the car slid sideways a bit under full throttle .

The kit sounds awesome! Before you start the development of your kit, it may be helpful to talk with other folks who have Turbo'd or SC'd their cars and see if they had any lessons learned that could be baked intoyour kit.
I'll start a new thread on that.

So why not swap the tube, too?
John, you slay me with all the great custom work you are willing to do to pull this project together, but won't make it right with a no-brainer tranny swap.
(Just one humble man's opinion, though, as I haven't walked in your *****-whipped shoes.

Hahah ... Dude ... if you had seen the amount of work that I saw this weekend on Goldmember, you'd believe JohnK could make a 928 do the "Spy Who Loved Me" thing in 2 weeks. The man is an animal.

It is about calling it quits when I have to. How much more money will I really get for the car with a 4 spd?...probably not much. Actually, the 3 spd is cool because it shows how much mid range boost the turbos can really make for you. 1st gear, 10 lbs of boost by 3750 RPM. Only the positive displacement can match that boost curve.
The ultimate would be a 5 spd Goldmember, but we all know that will cost as much as the car is worth. I do wonder how it would perform with more gears...the 1st and 2nd gear would be very fast I am sure of it. I want to do it on the conservative side so I can get back all of the development costs, afterall I am not going to keep the car...well maybe I will. Afterall, it is quite stealthy in apperaance....just ask the guy with the Blue Lancer Evo III with the KY plate "ByByV8". Good thing for him I had the 3 speed or it would have been even more embarrassing.
Who said anything about being "PW"? I need an S4 project, I was working it all out in my head while in the shower yesterday AM. Somebody stop me before I wear myself out...
