    bleeding the air

    all cooling systems need to be burped. Dunno what you mean by they dont. If you mean air shouldnt be getting in there then i guess ya, but air tends to get trapped in there after doing a cooling system flush and people usually just leave it.

    Weird transmission sound

    maybe the band needs to be adjusted? I know you can adjust them in some cars by just pulling the pan but im not sure if you can in the supra, Might just be worn? Are you properly checking the fluid level according to the tsrm?

    Unknown Antifreeze loss, Turbo?

    Does the level in the overflow ever get near the top when hot? I would get a pressure tester for the cooling system and pressurize that to see whats going on. If your radiator cap is bad it could be letting out all pressure into the overflow, makeing that tank spit out coolant onto the street...

    Those with Megan Racing Track Coilovers PLEASE HELP

    Im happy with the height the rears are at, if i would have set it i would have done that anyways, but it just seems like it should be able to go lower. Also, can you explain to me what youre talking about with the spring rates? Why would a higher spring rate cause it to bottom out on the...

    I did inspect all these parts before i put it all together. You cannot cut the bottom of the threaded part as it is part of the damper as stated above. However, in the sleeve part, with enough effort, you could make it go lower. There is a larger diameter cut down the tube where it allowes the...

    Megan coilovers?

    I assume the right ones are on the front because the coils are thicker for the extra weight. And what i mean by dead coilsis just a spring that doesnt have barely any tension on it, just to fill the empty space so the spring doesnt float, because i have about an inch of space to move the spring...

    what oil are you guys running in ur 1jz?

    why would you want an oil to be its thinnest on cold startup? Wouldnt you want it to be fairly thick as the mechanical parts havent expanded and havent had time to tighten the clearances?

    Megan coilovers?

    My preload is set to basically 0. The front hieght adjustment can go much much lower, but the rears are maxxed out and still not very low. The front suspension also seems to compress much more when going from the car being raised to on the ground compared to the rears. Can i buy some sort of...

    head removal

    You can put a piece of tape around the vac line and one on the port and color them the same color, just get a pack of sharpies all different colors. You only need to have the colors for the general area they dont ALL have to be a different color all over the engine.

    I was in the interest of a 2.5" header back custom exhaust. I dont have acess to a tubeing bender but i can weld. I was wondering what the cost for some bult pipeing would cost for the length of the exhaust? And how much in labor would it cost to have it bent to my likeings? I see these catback...

    Low idle oil pressure?

    The times my pressure drops even more than 2 psi is after i have ust done a high rpm/full throttle pull for a little bit. Im afraid to put an oil rated less than xw-40 in fear my idle pressure will drop even more
