Started my engine for the first time since the rebuild! It sounds really good and throttle response is much better! The valves are a bit noisy, but I’m told that’s a function of the performance cam. Still, I expect it will quiet down a little bit after break-in. Prior to start-up, I lubricated the cam area and “spunâ€� the engine with the spark plugs out to distribute oil. It’s not yet all roses and rainbows though… It seems to have a pre-ignition problem and wants to keep running after turning-offf the ignition. When time permits, I need to check the timing, set the idle lower and may need to change-out the old mid-grade gas for premium. For the moment I c…

I've done a good amount of searching now and I haven't been able to come to a conclusion. I bought a Facet-Purolator electric fuel pump from ebay that was advertised at 2.75-4 psi. In my mind that was perfect for the Z car so I did a buy-it-now (at a killer price imo). Fast forward a couple days and the pump arrives only the packaging says 4-5.5 psi range. Still is brand new and made in the USA Ebay woes aside, would you feel compelled to run a pressure regulator with this pump? I have read 3-5 psi for our cars is ok (stock L24 with 4-screws). I understand it's not a bad idea to run an fpr but does anyone think it would be required in this case? Is half a psi rating any…

I just bought an L24 engine for a spare to build for my 73 240Z. The engine I bought has the vin number 187769. I thought this number was very high for an L24 engine. The engine also came with an automatic transmission as well. Would the auto trans have anything to do with the high vin number? Brad Richards

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 …

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
