Mates I've decided to replace the clutch in my Z, as well shifting is becoming a bit tricky sometimes and I'm almost postive it slipped last evening. Question is this, would getting a stage one (Exedy) clutch be worth it. I'm don't do any racing of anykind - as well I only have one car and I don't need to break something - but I do have a lead foot. Opinions, suggestions are welcome Secondly, since I'm doing a clutch I decied that I might as well get the old flywheel machined. What is the best/easiest way to remove the flywheel without using air tools - as I don't have any? Thank Jan

Hello, I have a L28 in a 75 280z. I want to add a turbo. 1) Are there turbo fitted intakes readily available that I could install on this motor? Does does it make more sense to buy a ZX motor? If so is there a preferred year? 2) And does anyone know if the blocks have any much changing over the years, thicker cores, webbing etc? Thanks Robert

Guys, I got my engine back from the machine shop and it appears they have lost one of the two steel sleeves that help to align the head, gasket and block. Anyone know where I might pick on up in the Atlanta area? Are they really necessary, or just expedient? Thanks Craig

Sometime in the last several months, there was a forum post detailing the design of a wood engine stand. Does anybody have the link? I searched, but couldn't find it. I need to build one today since I'm buying a F54 engine tomorrow from a forum member in Canada and I'm transporting it on a flatbed truck so I want it to be stable. I don't have an engine handy to take measurements.

F54 and P90 1 2 3

I begin with saying that I'm sorry that I make a question that has been several times asked before. Been reading the topics, but still felt that I wanted to ask you guys for help with my engineproject. I bought a L28ET (F54 block and a P90 head) for my 240Z. The block has new rings and bearings, stock turbo pistons. The head has been shaved .074", with the proper single cam tower shim, multi angle valve job, intake runners ported and polished, slight deburring of combustion chambers, exhaust side just had behind the valve seat cleaned. So this should be a nice turbo-engine, and when I bought the engine I thought that I would use it as it is+EFI, but lately I've been pl…

78 5-speed seems to be running strong after about three years of rebuilding. However, now that I've got it back on the road, the gear shift is buzzing in all gears. I paid an experienced Z mechanic to rebuild the transmission about a year ago and it's going back to him next week to review my DIY work. I'm fishing for probable issues before I start questioning his work. I'm also getting some whining/roaring from the drive train. I initially assumed this to be the rear end bearings since that was about the only thing I haven't replaced or rebuilt, but I'm now wondering if it is all related to the transmission rebuild. Thanks for any input. Sid

I've got a leak that on the hydraulic hose mating to my clutch slave cylinder. It appears to be metal on metal. Should there be a gasket of some sorts? Seem obvious, but I wanted to make sure I'm not missing something else. Thanks.

Started a discussion over on Stanley's thread (link below) about bypassing the heater core and its effect on cooling. http://www.classiczcars.com/forums/interior-s30/49100-dump-heater-keep-fan.html#post428554 Didn't want to muddy up his thread so I've posted a couple of pictures I took to show what I was talking about over there. The first shows the large passage at the back of the head which should flow a lot of the coolant up through the block and through the head from back to front. The heater core supply hose fitting has been removed and is lying on the head. The second shows my finger in the big passage and visible in the heater core supply passage. That's what…

My '72 Z has an L28 engine and I recently swapped out the 4-speed for a late ('81-'83 close ratio) 5-speed. Everything went back together and works fine. When adjusting the clutch recently I noticed I don't have a return spring connecting the slave cylinder to the clutch fork. My friend's '71 4-speed has a spring that is about 3" in length. I measured the distance my spring would have to be and it is about 5" and there are places on the slave cylinder and clutch fork for the spring to connect. I know some slave cylinders have this spring internal with the piston. Short of taking the slave cylinder apart, is there a way to tell if I need to go get a return spring? I…
