   Can anyone tell me the metric bolt size for the bolts holding the tranny to the engine on a 280ZX L28 engine? I just bought one for a spare engine for my 280Z, and intend to mount it on my engine stand. I'd like to have new Gr.8 bolts on hand ahead of time, but don't know the bolt diameter and thread pitch. Thanks in advance!

   I have seen many N.O.S. original braided hoses on ebay at crazy price. I do not personally believe in using very old rubber. How about group buy? I know a small factory in Japan that have already made few different reproduction braided hoses for Skyline Hakosuka GTR, Z432, and Ken and Mary GTR. These high quality made in Japan hoses take minimum order of 100. So basically 100 for upper and 100 for lower. I can invest money into these if I get enough interests. It will end up in the neiborhood of $65-75 each. I have done hand-made ones before and they are not for parts-to-supply quality. Please look at this Lower hose for S20 Engine(GTR/Z432 Engine) It takes about 3 …

   Clutch Slave opinions

   I need a new clutch slave cylinder for my '83 5spd. Nisan wants $77.81 for one. Parts stores are all over the board and as low as $19.74. Is this one of those parts that you should only accept a Nissan part? I don't mind paying for a quality part but Nissan seems a little ridiculous on this part. Let me know your recent experieinces. Thanks, Marty

    So I know I have a mech fuel pump on my 260z but few days after I picked it up and driving the hell out of it! I started to hear this sound that kinda like a slow air pump for a fish tank! and its in the location of the electric fuel pump but looks like nothing stock and is a small box thats wired in! and has fuel lines running to it! Its now making a kinda odd knocking sound as if its dieing! but i'm not sure if I even need it!

    Manifold torque

    What is the proper torque setting for stock intake and exhaust manifold nuts on a 240Z? I searched and one person said 8-11.6 ft lbs in one thread. Another said 10-13 ft lbs for "small size" nuts and 25-36 lbs for "larger" nuts. All of the nuts are 12mm, except one that holds the fuel rail on is 13mm. The Haynes manual says 8 ft lbs. I can't find anything listed in the FSM. -Mike
