As you may know, I am going to be doing a turbo swap. I know someone else in town that was doing the same thing. He said that you can put the flat top pistons in a turbo application. This would raise the compression ratio a little. I have thought of it, but I am not sure if he is pulling my leg. I would like to know from the forum if it would work. I'd ask on Hybrid Z, but I can't get on the website from where I am at. :disappoin Greetings from the middle of nowhere...............

I just got an "Injector Seal Kit" VB Part #57-200 ( pg. 80 in cat. 44, upper right corner). I'm puzzled as to what's inside. There are six smaller o-rings which I think go on the injector tips, and six larger rings. What are the larger rings for? Don't see it in the repair book. thx

Just a quick question. The elbowed nipple on top of my valve cover is screwed. As you can see....the hose it pushed all the way up against the cover because of the missing section. Anyway....in my search for a valve cover, I am not noticing any with the "2400" on top. All I see are the "Nissan OHC" ones. No big deal, just wondering which years had these. Picture below.

I've never heard of a L28 block cracking so I ask, where does the L 28 leak water into the oil? My first thought and repair was head gasket but that didn't fix it.

I'm doing the final assembly on my engine and have lost the torque specs for the crankshaft cap studs made by ARP. I've tried calling them but I missed them by 1/2 hour and today is Saturday. Can someone help me with the proper torque specs before Monday? ARP Part # 202-5406. I'd hate to have to sit around until then. Thanks guys. Ed

I would love to do this to my L24. A single drive system is much more appealing in every way. Do any later L6 platforms use this drive that could be moved over to the L24?

I have an AFM boot that is in good shape but it's hard as a rock. Is there anything that you can do to restore rubber to make it more pliable?

I am going to put an E31 head, with 280 valves, on an F54 block. When I place a 2.8 head gasket on the E31 there is very little room between the valve and headgasket to unshroud the valves. Am I missing something? I know several people have put the 280 valves in the earlier heads, did they have custom head gaskets made to allow for room around the valves, and grind the top of the cylinder bores to match ( .050 above top of ring travel) or just clean up the head as much as possible Bob
