bout 10 to 11 bucks a quart. since I dont change the oil but once a year it's not too bad.

I use Amsoil 0W30 oil. expensive but worth it. the first number (0) is the weight when the oil is cold. the (30) is the viscosity when the oil get hot. 30 weight is the protection that gm recommends. the newer engines have higher tolerances which is why gm does not recommend thicker oils...

chinese corvettes well, if the dollar is the bottom line then it will be chinese workers building the american corvette sports car. I would rather pay a little more and keep american workers building our own cars. Seems that squeezing every dollar until it screams is the very highest priority...

sts turbo a friend of mine had a 2007 z06 he would race at weekend track events. I also had a new viper which would outrun his z06 so he installed the sts twin turbo setup. He shipped the car to a tampa authorized installer and all he had was grief. finally he had a firey accident when one...

Mr. Zagger thanks for you information. I performed the operation to my 2000 vette and it was flawless. Exactly as your pictures stated. I bought a bronze gear and the job was a snap. Thanks again for your help. edram

hand held tuners. I believe much differently than others on the forum. They ARE worth the money. I have a automatic trans c5 so it came in real handy in raising line pressures to vastly improve shift points and firmness without getting carried away. Also, I did load the predator tune into my...

Installing Long Tube Headers I installed dynatech longtube headers with xpipe and cats mated to slp catback. I also installed vararam b2 with new air bridge and couples and throttle body smooth baffle. I found that I hear a lot more valve train noise and ticking than before. Also the 02...

vararam intake will give you the most power. an xpipe will change the noise and stop the occasional popping but little to no increase in power. dyno proven. vararam will not give you better dyno numbers because it is really meant for forward moving vehicles and that rush of cool air is what...

problem solved. had a dyno tune and found out that when installed a complete header system, if the 02 sensors have been slightly moved from the stock location, that will sometimes conflict with each other. In my case, the left sensor was taking fuel away while the right sensor was compensating...

Just installed a set of dynatech headers/xpipe/highflow cats and slp powerflo cat back. the car is running erratic. sometimes it idles down until it almost turns off or when I am driving it will either surge or struggle to accelerate. all the 02 sensors are installed. the installer said that...

rebuilt title Hi, I do live in Florida and there are a lot of cars sold here with rebuilt titles. These are insurance payoffs which means the insurance company thought it would be too much money to fix so they just paid the policy holder and auctioned off the car at a ridiculous price. There...

vararam I installed the vararam b2 in my c5 and noticed more seat of the pants power especially at speeds above 50mph. I feel it is the best cold air intake on the market. install was about 3 hours. If youtake your time and install carefully, it looks like a factory piece. eramos.

increase horsepower?? who have made good choices and are churning out 350hp at the wheels. if you change the rear gears you will have a gas mileage loss at a time when gas is 3.00+ a gallon....bad move. torque converter..torque converter ...torque converter. it will give you that launch you...

engine noise Hi, I have a y2k coupe and it also has a slight ticking noise when its cold. After it warms up it goes away. Dealer said it happens with most 2000 cars or ls1 cars. I am the second owner and the original owner said it did it when it was new. He was quite bothered by it and the...

gears with a compromise A higher stall converter is big bucks to install and purchase. True it will give you a more agressive launch but you will blow off you tires and lose a match and rear gears will certainly cut your quarter mile times with a trade off in top end speed. just depends what a...

horsepower You dont need to spend 8 to 9 grand for horsepower to have fun. I have had a few very powerful cars and I can tell you it will cost you lots of money and be less reliable. You want to upgrade your power output a bit so you can have an advantage over stock. May cars have had...

I have to take some shots of my car now. it looks very similar to yours except ls-1 badges on the side and totally blacked out front and rear. I found a site with long tube headers for c5 ls-1 at 400.00 bucks. no clamps or anything included just pipes. any good muffler shop can set it up for...

added same mods plus some... I added all the screens front/rear and brake duct along with stainless cowl screens and it looks great. my car is black on black also. I just added a SLP cat back power flow system and it sounds great. also added a diablo predator and loaded the tune program and...

automatic or 6 speed Hello. In high horsepower cars the automatic is much better in drag racing than a 6 speed manual. first of all, automatics can withstand much more power and torque than any manual transmission except for lencos or the like. Regular 6 speeds definately would spill there guts...

top speed Yes the top speed for a coupe is greater than a frc. the frc has dirty aerodynamics at high speeds while the coupe has better wind tunnel numbers. More weight + a little less power + much better top end aerodynamics + faster top end speed. Top speed for a c5 z06 is 181. for a c5 coupe...
