^^Good point. Merry Christmas, by the way!
Personally, I'm going to try and keep my car relatively streetable, and focus on losing weight as opposed to adding tons of power. This is my wish list: Downpipe Odyssey mini battery Racing seats, without sliders Lightweight suspension parts: coilovers, suspension arms, etc. Try to eliminate rear swaybar. Remove cruise control, air pump, power steering and maybe AC as well Smaller "metallic" cat converter, lightweight titanium exhaust Moderately-sized aftermarket IC, radiator, and oil cooler; there's no point in dissipating 500hp worth of heat when you're only making 300-350hp. I'm hoping to get down to 2600, but I'm not in a rush to get there. For more ideas, see this thread: https://www.rx7club.com/3rd-generation-specific-1993-2002-16/weighed-fd-last-night-what-do-yours-weigh-594039/ -s- |
Here's some of the things you can do. I've done most of these already and plan on doing the rest at some point.
Single Turbo with downpipe. Amuse full Titanium Exhaust downpipe back Braille 11.5 pound battery Recaro SPG Seats without sliders Remove Air Bags and ABS Carbon Fiber Driveshaft Carbon Fiber Doors Carbon Fiber Hatch with FAL Lexan Window Wiring harness simplification Sleek head lights Interior removal Heater removal A/C removal Powersteering removal Single gauge/dash cluster. Stack, Defi DSSC, etc... Windshield washer fluid removal CE28N Wheels with Toyo T1-S tires Titanium or Aluminum open end lug nuts Two piece brakes with aluminum hats Racing Beat Aluminum Engine Housings Lightened Engine Rotors Custom Intake Manifold Electric Water Pump Kiwi-RE light weight e-shaft Removed unnecessary bolts, replace others with hollow titanium or aluminum or even plastic bolts Speed Glass Remove windshield wipers |

Best of luck with your project :) |

Where do you get "titanium suspension pieces (trailing arms/Toe links)?"

Couple thoughts regarding the items listed above and a few new ones:
-An electric water pump is probably heavier than the stock pump since it has an electric motor instead of a simple pulley. -The stock seats are very light. The sliders are heavy though. Replacing the sliding assembly with fixed units might save as much as going to aftermarket seats, granted not bare bones race shells. Either way it's not going to make much of a difference, especially considering the loss in convenience -Removing the side impact door beams to save a few pounds??? -get real, unless you plan on using a cage. -The stock driveshaft is very light. Most of the weight comes from the pivot points and the ends, so switching to an aluminum or carbon fiber shaft isn't going to do much of anything. -A lot of weight could be saved by switching to an aluminum sheet metal intake manifold and throttle body. -none of the HVAC stuff weighs much except for the A/C mainly because of the parts in the engine bay. -Tow hooks and bolts are heavy. I removed 1 of the 2 on each end of the car. -The Rear carpet is heavy -The rear shelf is heavy -The dash board is really really heavy, but also structural. I understand why Dodge spent a fortune creating a magnesium dash support structure for the Viper. -The steering rack and shaft is heavy. Not sure I have the guts to try an aftermarket unit though. -Tube frame front half! :) -Shocks/springs -I know someone that created a push-rod setup so he could use shocks that are about 1/3rd the length of the stock units, but he gave up some room in the trunk and a lot of wheel travel in the front. -Glass sunroof. It is very heavy, but I love having it |

Nice looking setup. Did you retain a heater connection, turbo coolant lines, and T-stat? In any event, I stand corrected.

I also eliminated the thermostat because my water pump has temperature variable flow control unit that speeds up or slows down the coolant flow depending on the temperature.
Craig Davies? Mazier? Did you fab the plate to replace the water pump? |
