    3.73 or 4.10

    I have 3.73 gears now would it be worth it to swap to 4.10 or would the change be little to none ? The car has heads, intake, and cam with a stock T-5. I would like to get my 60' time down. Thanks :flag:

    PCV Valve help !!

    Can the PCV vavle be capped off or deleted or can it be vented into the air instead on the intake ? I ask because I'm 99% sure the PCV valve is my vacuum leak. I do have the valve cover breathers is that hurting or helping me. Will it hurt the motor if I cap both the valve and the intake...

    More Air

    Thanks. So the stock air box is fine for N/A but what about nitrous, gt40 heads and intake ? Will the stock box flow decent or would the fender set up be better.

    More Air

    Question: Is the stock air box a big restriction if it has a K&N in it ? It has a huge filter and it sucks air from the fender through a good size hole. Is a fender mouth CAI going to produce more air or colder air ? I just hate that 90 degree turn right before the MAF on every fender mount...

    Throttle body upgrade ??

Right now I have 65mm TB, if I did some minor porting to my GT40 intake to get rid of that 69mm lip would a 70mm be...

    MT Drag radials

    Hey guys, Will a 275/50/15 on GT turbine wheels rub on a Fox body with stock suspension and axle shocks. Would 255/60/15 be a better choice. I would like to keep my stock quad shocks on if possible. Thanks

    Fuel pressure

    My computer is giving me a code that indicates the engine is running lean. At lower RPM (1600)the engine will miss alittle and sometimes around 5300RPM or so it will lose power like a dead shot. Is it starving for gas? If I turned up the fuel would that help fix this problem? I'm at 45 now...

    More wheel questions

    Question: Right now I have stock 16" ponies on my LX with 225/55/16 If I went with stock 15" turbines or 10 holes with 225/60/15 or even 245/50/15 would that make the car slightly faster in the 1/4. Would the smaller light wheel with less rotating weight make any difference ? Would the smaller...
