Official lightening the mk3 thread!!!!

if you have the money, use chromemoly tubing for a roll cage. maximum rigidity at its lightest.

weight transfer is great when drag racing you want the weight in the back for traction but if your setting up the supra for drifting then you should probly lose as much weight as possible

Well, I want a Supra to take down Highway 101 on the west coast next summer. I think all the twists and turns might flex he frame a little too much. I'm going to have the top off, so I was thinkin' a brace would be excellent for this situation. Thanks. I'll get hold of Weezl once I actually own a good running Supra.

As someone that drives on the west coast 101 on a daily basis I can assure you it is perfectly fine for your supra. You really don't have to worry about that.

I think unless you wanna turn your car into a drag car, not a tidy, suprisingly quick(to ppl who hate "Jap crap") everyday driver. For those looking for a bit of go on the streets, fork out a bit of coin on the engine and maybe lightened running gear. Pulling all the rest of the bits out like heavy seats and electric motors is a waste of time for ppl wanna street car. it is supposed to be a luxsury sports car. I don't wanna get rid of all that if i wanna drive it everyday. These cars are heavy, so what! theyre supposed to be. That is why they have tuff engines.

If you wanna drag car, chop away!

one thing about drastically changes the weight of the flywheel and size of pullys is that it will make you car run differently and you have to be careful. the flywheel is the rotating mass that keeps the crankshaft and whole engine moving inbetween strokes so if you lighten this you won't have as much mass rotating.. it'll change the balance of the engine.

[cars4me89]

another change you could make to help with traction, weight.. anything is relocating the battery to the spare wheel well since I'm gonna assume you're removing that to save weight.. relocating the battery to the trunk will give you at least another 20 pounds right over the rear axle.. where you want weight

good info to know

Lighter flywheels are a popular upgrade. Usually flywheels are balanced separately and then the the whole rotating assemby (crank, flywheel, journal weights - instead of rods and pistons) are balanced.
Therefore in most cases it won't affect the ballance if you use a lighter flywheel assuming it is prebalanced. It will change the critical frequency of the assembly though but most engines never hit their critical frequency anyway.
Besides the decrease in overall weight a lighter flywheel will make the engine spool up much faster. Faster engine spool = more hp.
Does anyone know the weight of a stock flywheel?

I'll admit that in previous cars i've eliminated weight to try to augment the overall performance. The weight I eliminated usually came with drawbacks, like having to shift while using both hands to pray i dont get a flat (because the spare and hardware was removed), or hoping that i dont pick up more than one girl at a time (because the rear doors were gutted and rear seats removed, and A/C system eliminated).

I'll say this for the supra, if you want to increase performance, horsepower is not hard to come by. Maybe you want to augment the motor, trans, or rear end? Perhaps just a high flow air filter? A high flow (legal) cat and less restrictive exhaust all together would help the base motor run better and stronger. After your pedigree restrictions in intake and exhaust have been aleviated, you're ready to tune. Find a stand-alone engine management system and work out any factory fuel curve kinks you may have.

Before you go replacing hard parts on ANY car to try to get more out of it, start putting quality fuels and lubricants in it. Just like your body, you need to treat your car well. Eat healthy foods, feel better. Run quality fuels, get better milage and performance. Avoid fuels spiked with ethanol, as alcohol yields far less BTU's than gasoline, and as it damages fuel systems not designed to run alcohols. Use a synthetic motor oil, or at least a branded petroleum quality oil. In short, you get out what you put in.
