You are correct, I was typing too fast and did not proof what I had written. I must have meant to write decreases braking effectiveness or efficiency, not decreases distance. Sc & RX, Larger overall diameter increases braking distance not decreases braking distance. They do reduce the...

That must be a blast to drive. The only real fast times I have had were on a GPZ 750 I used to ride. And one time in a Pro Street car and then in a "dragster" that was on a rail at some place in Dallas. Is a race car fun like a motorcycle, but not the same piss in your pants feeling you get on a...

No, that was not my point not at all. There are lots of lighter rims that look better, are wider and lighter than stock from companies like: Volk, Motoforge, OZ (Superleggera) Gram Lights, Work, Weds, Racing Hart, etc... The point I wanted to make was that a lot of the aftermarket wheels out...

I read somewhere that losing 1 pound of unsprung weight is the same as losing 2 pounds of sprung weight. So it really blows my mind when I see cars with wheels on them that I know weigh more than the stock ones they too off, even if they are the same diameter. One can go to: wheelweights.com to...

Every single piece of information I have read about Supra TT wheels indicates a +50 offset.

Thank you for your reply. I have already changed to a 2,800 stall T/C, installed headers with a complete 2.25" exhaust system with "X" pipe, modified my intake box and had the Apexi S-AFC II programmed while the car was on a dyno with a wideband plugged in the O2 sensor. Yet I am only at 225...

My car is a 1994 SC400 with only 19,000 miles on it. Do I need to replace the timing belt because of its age?

Found the answer, there is an emission systems diagram stuck under the hood. I noticed it when I was lookintg at something else, should have seen it sooner but I guess I am too tall.

I did a search and saw lots of posts on interpreting specific codes and saw recommendations for people to go to the autoparts store to have their codes read and I also read a post indicating that the autoparts store's OBD II scanner would read an OBD system. However, I did not see anything...

I have read that wrapping the headers will make them rust quicker.

Thank you for the reply! I think I am starting to piece this together. The problem is that the car was in the shop and one of the things "installed" was an EGR delete kit. The removal of the EGR system involves plugging those three holes you mention that are at the top of the intake. When I...

Could it be the new cat burned off some stuff that is fouling your O2 sensors?

Do you mean he said it would not work to mod the cams for the 3UZ heads, or that it would not work to put the 3UZ heads on the 1UZ, or both?
