How To Buy And Sell Junk Cars For Profit

Well, in the most basic sense, the exhaust pipe that you find in your vehicle is a tube that actually guides any exhaust or waste gases away from your car’s engine. It is very essential for if the waste gases simply accumulate in your car’s engine, you and your passengers can actually suffer from poisoning of these gases and it could be very lethal.

BPU(TM)’d Supras run a little on the rich side as far as fuel ratios go. This hurts power. What it does do is provide a safety margin that makes engine damage through detonation unlikely. If you get a fuel controller, and tune it properly (on a dyno, with an accurate EGT gauge, and a high band O2 (The Stock O2 sensors are not accurate), then you should be able to gain a noticeable amount of power. One of the most popular electronic fuel controllers is the A’PEXi S-AFC. The Fields SFC is good too.

4) Also watch out for fraudulent promises. Car salespeople at car dealerships are notorious for this. Get any promises in writing. If the car has a warranty and what is actually covered can be quite different from what the salesperson says. Remember, the salesperson doesn’t care about you and only wants a quick sale. You must make sure it has the warranty you desire. The salesperson at Farmerville Motors stated that the entire emissions system on the car I purchased was covered for one more year – upon taking the car to a GM dealership it was found that only the catalytic converter price guide was covered, not any part of the OBD and emissions system. Get it in writing.

Make sure all exterior lights work, headlights, tail lights, brake and backup lights. The key will likely have to be in the “on” position for you to check the lights. Check out the seat belts too.

The next mods, are the true twin conversion mods (or TTC). This modification disables the Sequential twin turbo operation, and causes the turbos to run constantly in parallel (both on at the same time). This is supposed to allow for slightly better mid-range power (before the secondary turbo would normally come online) and allows for a smoother power band, without the abrupt boost increase caused by the transition from primary to secondary operation. However, this does noticeably decrease low-end power, and increases exhaust noise levels, and therefore may not be desirable on the street. Two types of the TTC mod are, the traditional TTC mod which includes 2 methods, wiring the actuators, or installing a one way valve, and the Electronic TTC mod (ETTC).

Yes, the stock fuel system is very safe and reliable to 450RWHP, although I would recommend a fuel pulsation damper bypass. Anything over that, and I would highly recommend having the car dyno’d, and using a wide-band O2 sensor (not a cheap A/F gauge connected to the stock O2) to check the fuel ratio at your high boost setting. 11.5:1 would be a safe fuel ratio.

A flickering warning light is serious. A light that is showing a clear pattern of off and on is your worst case scenario light. This likely means you have a severe emission control failure and every time that light flashes your catalytic converter is being damaged by a misfire. This means your catalytic converter is overheating and can start a car fire. Pull over and get towed. This is not a time to try and make it a few miles to your destination.
