I'll check the measurement tonight and let you know. Guy

Nix the last question....Garrett at Motorsports said it's the 21-2122, so I ordered it. Thanks everyone so much for your help. Now I'm gonna put her together! Carl ....Brandon(my son) said you e mailed him re the orange 510. Let me tell you it's a screamer.....feels like Road Atlanta! Thanks for your help. Guy

Carl Motorsports has a 21-2122 for the 75-78 coupe, 79-83 coupe non turbo, and 84-86 turbo.........they also have a 21-2123 for the 75-78 2+2, 79-83 2+2, 82-83 turbo, 84-89 non turbo.......which one of these two items is correct? Thanks Guy

Thanks Mark......Glad the Brits like the Z's too!

Bo I ordered the 83 turbo collar and it is very short (and as you mentioned doesn't work). I have a 77 5 speed tranny and the sleeve for it is longer than the 71 Z sleeve. I measured the height of the clutch finger tips (distance from the flat surface of the flywheel to the point of the clutch fingers that the TO bearing contacts). The 240mm pressure plate is actually shorter than the original 240z pressure plate. Wouldn't that mean that I need a sleeve that is longer (not shorter) than the 240z sleeve to reach the shorter pressure plate?

Bo So what I am going to do is use my stock fork, my stock TO bearing and the collar for a 280z (non turbo non 2+2). You wouldn't happen to know what MSA part #, since different 280 non turbos call for different collars. I really appreciate evryone's help with this. Changing the clutch, flywheel and pulling the tranny is a job that I love to do only once! Thanks Bo and Stephen. Guy

Bo So if I wanted to install the 240mm flywheel with a 240mm Exedy clutch and disc with my 1971 4 speed transmission........Could I use my stock fork,stock TO bearing and stock sleeve, or would I need to change any of my stock items? (ex. a different sleeve etc.) Thanks for your input. Guy

How about if I want to hook the 240mm setup up to my 71 4 speed.......what fork and sleeve would I use in that case? Remember the slave cylinder is different on the 240z.....the plunger rod actually goes through the fork end.....could I use my 71 4 speed fork and sleeve, or would I need a new fork and sleeve, or just a new sleeve and the old fork? I'm getting all forked up. Thanks for your help. Guy

I bought a 77 280 zx 5 speed......Will that fork and sleeve work? The last thing I want to do is have to pull the transmission cause of the wrong fork or sleeve. Guy

Can anyone tell me what clutch fork and clutch sleeve can be used with the 240mm flywheel and clutch. I bought the fork and sleeve for the 82-83 turbo. If I install the fork and clutch sleeve with the stock TO bearing, will that combo work with my 71 4 speed or my 77 5 speed in my 71 240Z with the 240mm flyheel and clutch? The Nissan part numbers are 30531-po151 for the fork and 30501-k0404 for the sleeve (both are for the 82-83 turbo with 240mm flywheel)

Thanks Frank.......The 510 is my son's....he's sick too! I can't wait to see a fresh coat of Safari Gold 2 stage PPG on the resto. Yours looks smokin' in gold.

Me also Doug. Hmmmmmm 3 Zs 1 300ZX and a 510. Think I could talk my wife into it?

Someone wanted to know how it held up? I can tell you.........beautiful 'cause I now own the car that Bruce fixed. I didn't even know it had been done! Great job Bruce....just like the entire resto you did on the rest of the car. Guy

Nice pics in Nissan Sport Magazine Carl! The car is awesome......How 'bout some pics on the Forum? Guy

Voila......I think you guys nailed it! Good detective work. Oil makes things run slicker and cooler.

The rocker geometry looks to be way off toward the pivot. How much was shaved from the head? Did someone do a wipe test on the rockers and cam lobes? They say to never use rockers from a old cam on a new one, and even when they are reused on the same cam, it is imperitive to keep the rockers and lash pads in the order that they were removed. Keep us up on your progress! Guy

The damaged front clip is gone......the new one is ready to go on.

Steve, Doc is the one building my P79 head and also my E31. He's a trip......I don't know if you've met him, but if you haven't, it worth a trip! I'll go with you if you come through Richmond. He said I should use the 240mm clutch with the 28. I'm hooking it up to the 240Z 4 speed (is it OK to use that fork and TO with the 240mm clutch?) Just having a ball building all these combos and will let you know what the dynos and times are like after the mods. John Morton did pretty good with the 2400 didn't he? Guy

Steve The reason I was asking is because I too am building an L24 and an L28. The L 24 will be bored 40 over with a E31 head. Isky is carving me a stage II cam. We are not shaving any thing off of the head but are putting stainless steel swirl valves and stock valve springs. We're doing this to keep numbers matching. We're also building an extensively modified F54 with the shaved(.080) P79 head. Everyone needs 2 engines for the same car! Question.....What do you think the 24 will be putting out at the crank? Also.....the L28 will be putting out over 200 H.P. so I bought a 240mm flywheel. Will the new clutch require different fork and TO bearing to work with the flywheel?

Red dog What else is Rebello doing besides stroking the 2400 to get it to 220 H.P.? How about the head......what mods are they proposing (cam etc.). Guy

The Datsun was at some point and time hit in the front left. The perfect front clip will be used to make a perfect mend. The bucket of nuts was found in the vent pocket when we cut the section open for repair. There is one angry squirrel waiting for the return of the '71. We'll keep you posted. Guy

Yes.........That includes shipping. Guy

They have already set me up with a discount. They are wearing the numbers off of my Visa! Just talked with Fred at Pence Nissan. He ordered them from California. List $69.00 ......my cost $55.00. Thanks again for your help Will. Guy

Thanks Will.......I'll call 'em in the morning. Guy

Anyone know where I can buy flat top (standard 86MM ) cast pistons for my 1983 280zx engine? The Nissan part # is 12010-p7912 Guy
