    Installed clutch, put the starter on and motor won't turn over

    I replaced the clutch today on my 1JZ/R154, but I have a weird problem. After I bolt the starter on and try to turn the crank pulley with a wrench, it only turns about 1/10 of a full rotation of the crank. It sounds like something hits something and it won't go past it, then I can go back about...

    First off, I want to thank Joliroger4 for giving me great step by step instructions and answering any and all of my questions. Thanks a lot! It took me quite some time to finish it up, but it was mostly because of lack of time and because the car is my daily driver. A couple weeks ago I...

    Anybody have experience with Exedy double/triple carbon clutches?

    Thinking if I should get one, seems like not many people have experience with these. What's the proper torque rating for these(triple) anyway? Seems like every site is rating them different. Let me know what you think about these clutches or at least know someone who has one and likes it.

    Misfiring?

    I had this problem before, but it went away after I changed my plugs. I changed my plugs to 3330's and 500 miles after one of the cylinders started misfiring occasionally. Now 1500 miles after the plug change it's almost undrivable. Before it used to do it on hot days and now it doesn't seem to...

    What kind of oxygen sensor does 1JZ use?

    I still have the 02 sensor in the engine that came on the clip and has gone bad. What do you guys use as a replacement? Also does it matter how many wires are on the 02 sensor? Mine has 3, I also searched Advance auto and autozone for it, but couldn't find one.
