Here is the info on the Dinan mods done so far to my '96 1.9 for those of you interested. This stuff is scanned right out of the brochure so no wise comments about the Marketese please!
Larger Throttle Body coming soon! And yes, for those of you who have asked, I do have enough points for the Dinan badge!
Free Flow Exhaust
Dinan's new Free Flow Exhausts for the Z3 and Coupe provide substantial power gains, without the excessive noise associated with typical "performance" mufflers. The Dinan exhaust features a rigid and durable muffler case, manufactured from 20 gauge 304-stainless steel for optimum corrosion resistance. The Dinan Exhaust also reduces weight. Internally' the systems feature Dinan's Tuned Resonance Chamber technology, which provides the optimum balance between maximum power gains and a civilized, yet sporty exhaust note. The large, polished stainless tips give the car a tasteful performance look as well. The exhaust is 50 State Emissions Legal*.
Stage 3 Suspension
1.9, 2.3, 2.8 Liter Z3 and Coupe - Stage 3 Suspension System Dinan's Stage 3 Suspension System adds front Camber Plates to the Stage 2 System for increased negative camber on the front wheels The increased negative camber dramatically improves turn-in and further reduces understeer for the more aggressive driver
Stage 3 System Components
Nothing creates a performance look and feel more than a set of larger wheels fitted with wide, sticky tires. An aggressive set of wheels and tires tenaciously grip the pavement for better handling and braking. Improved agility also makes it easier for your to maneuver in traffic and avoid accidents.
Dinan offers two wheel designs; both allowing fitment of the largest wheel and tire sizes possible. To achieve the Dinan quality, fit and finish, we carefully engineered and road tested every wheel and tire for proper fit and maximum grip. For the ultimate in performance and quality, we recommend Pirelli tires especially the P-Zero Asimmetrico. If you are interested in a performance tire with more longevity, the P7000 is an excellent choice. When you buy a set of tires with Dinan wheels, state-of-the-art mounting and balancing is included at no charge.
Dinan 18 Inch - One Piece Wheels The understated elegance of these aluminum alloy wheels is a pleasure to gaze upon. The aggressive wheel/tire fitments bestow superior handling at an affordable price. The combination of 18 inch wheels and aggressive tires give unmistakable visual hints as to their capabilities.
In keeping with Dinan's production quality standards, the wheels are manufactured from an aluminum alloy using the "Counter Pressure" casting technique for superior strength and a flawless finish. Our wheels have also undergone S.F.I., D.O.T. and JWL testing to ensure that they meet the most stringent US and international standards, as well as our own.
For the M Roadster and M Coupe, we offer an 18 x 8.5 inch front and 18 x 9 inch rear wheel set. The wheels accommodate 245/35-18 tires in front and 265/35-18 tires in the rear, for maximum grip. For all other Z3 and Coupe models, we offer the 18 x 8.5 inch wheels for the front and rear, designed for 245/35-18 tires. The wheels are sold as a complete set of four, and include all necessary hardware.
18 x 8.5" - Front / 18 x 9"-Rear One Piece Wheel Set $2100.00
18 x 8.5" - 0ne-Piece Wheel Set $1999.00
The Dinan-modified tuning parameters provided by the Performance Engine Software optimize fuel economy and emissions at light loads, then gradually shift focus toward power as loads increase. At wide open throttle, the performance software is dyno-tuned for maximum power gains. The software also establishes the proper fuel enrichment and ignition timing for optimum performance gains from further Dinan performance modifications. In addition, the Dinan performance Engine Software increases the stock rev-limit by 300 rpm, in order to optimize shift points for improved acceleration. The Dinan software also eliminates the top-speed governor. 49 State Emissions Legal*.
Currently: This product is legal in California only for racing vehicles which may never be used upon a highway.
..straight, taking your standard 1.9L car and adding the DINAN air intake, "chip", and the muffler (would be nice to have a slightly deeper tone), the total hp/torque numbers should increase by about 20. We know the rough cost of the software, do you happen to have an idea on the air intake and exhaust??
