280Z clutch and part number…..29 mm.

That makes this chart even more worthless. The Type B 4 speed in the chart shows 29 mm and is correct for the 280Z clutch……... 47 mm total. The 240Z collar is 10 mm shorter at 19 mm…… 37 mm total with throw out bearing. The throw out bearing is 18 mm. None of the collars in the chart have that 19 mm measurement for the 240Z clutch. Go figure!

Good job kcpope. I just remembered I have kept two collars with throw out bearings attached for future acknowledgement. One for 280Z and one for 240Z. I just went out and measured. The 280Z collar with throw out bearing is 47mm and the 240Z with throw out bearing is 37mm. This needs to be logged for future reference. The 2plus2 / turbo is in a league of its own. I didn’t keep one of those.

Wow……The S30 Datsuns are incredibly beautiful. This restoration is incredible in itself. Great job @Inline6…..I’ll bet your shirts all hang in same direction in your closet! 😂 It just doesn’t get any better than this restoration…… Perfection!

I agree…..That chart of collars seems worthless to me. What we need is a picture of three collars. 240z, 280Z and 280Z 2plus2 or turbo. Thats why I always ask Motorsports to send me the one of three that I need. I don’t want to pull a tranny but once. 🥳

It’s really very simple. If you are sure you have a 225mm flywheel, you can use a 240Z clutch and 240Z collar or a 280Z clutch with a 280Z collar……your choice. Call Motorsports and tell them you want a 240Z clutch and a 240Z collar and throwout bearing. They will send you the correct combo. My 280 motors with 225mm flywheels all run the 240Z cluches. I like them best.

Unwrapped my brand new gas tank from S30. It looks fantastic!

I have Exedy 240Z clutches (Made in Japan) in all five of my L28 Z’s and they are perfect. Do what you want, but if you order an Exedy pressure plate and disc and specify 240Z, you can then order the 240Z collar and throw out bearing from Motorsports and if you have any questions, those guys know what they are doing and can help you. They probably have the Exedy clutches too. If you do that, you can forget measuring…..you’ll reinstall with confidence! PS Make sure to confirm the size of your flywheel is a 225 mm (the facing looks awful wide in your pic) or you’ll need to order the clutch and collar for a 2 plus 2. Motorsport sales folks can help you with that too. 👍

This photo is correct.

I agree with Charles. If the throw out bearing is reversed it will fail. The rounded side should contact the fingers not the flat side. I had a machine shop install one in reverse and the bearing froze up and welded to the fingers. The wear on your fingers is not right……the PO reversed the throw out bearing. If I were you, I would buy a new Exedy clutch, disc, collar, bearing and pilot bushing, then you will know it’s right. Just make sure you know what flywheel you’re running, and make sure the rounded side ( not the flat side) of the bearing contacts the fingers. 240Z or 280Z pressure plates (225mm) are a different bolt pattern than a 2plus2 (240mm) flywheel.

Count me in too….NSX mid engine. 😵‍💫

How much timing are you running? BTW, you can’t be a tooth off unless you drop the oil pump. Timing is important in these cars. What are you running at idle?

Oh wow……Glad to know you’re still out there Zedy. Why not just strap a set of SU’s on her and “ Enjoy the Ride”. Last time I think you were on here, your wife had just brought Zedytwo into the world! 😆 Also, somewhere on this forum there is a link to a site that sells brand new Z gas tanks for $600.00. Some of the older tanks cause ongoing problems. Sometimes I think old gas is blamed for problems caused by other issues…..Just MHO. Good hearing your voice! Guy

Great purchase. Now you see what octave your wife hits when she hears you spent $9,000.00 on that Stroker motor! 😱

Yeah I’m a Sicko….Just like all the Sickoes on this site 😂 Your work is incredible….you must love puzzles too since it’s so much easier to buy a fairly rust free Z still these days. I would love to be closer to learn your techniques and borrow your tools. 😂 So much fun to watch your progress…..glad you are letting us tag along for the journey! I’m sure @Patcon would love to be closer too…..you guys have all the patience I’m lacking. Can’t wait to see the final product. Good Luck Guy

Brandon just fired up his new RB 26 normally aspirated. These are the numbers you’re looking at. The Datsun Spirit stroker does equally as well or better……much cheaper and more available parts. Just my humble opinion. Great work and I love the NSX!

Hahaha ……yep we were just browsing that last week. Happy New Year Site. The color is easy to mix. We use PPG.

……..or take your favorite IPA down to the paint shop. Brandon just painted his Z31 Safari Gold. I’ll see if he can help.

Pure art……I love silver.

It is most likely it is rubbing on your lower valence. There is a way you can adjust that valence. I can’t remember exactly how I did it, but it wasn’t rocket science and it was a quick fix. It only requires a minor adjustment to gain clearance and prevent the rub.

Eiji and I try to hit Dinwiddie quarter mile track once a year. He almost always has more motor than me, but I did beat his 280ZX with triples in my stroker 240Z. Eiji generally runs in the low 14’s and I in the low 15’s.

Seems to me if you have an average 120 lbs per cylinder in the first 3 cylinders, they are getting air from somewhere other than through the butterfly. Is it possible you have worn shaft bushings or a bad manifold or carb gasket. At first, burned valves came to mind, but with 125 lbs pressure its getting air in there from somehow.

Good to hear your voice Mike. I thought maybe you were spending some time in Hungary.

I hope Mike is ok…….anybody heard from him lately?

Same problem for me……..
