Best Flywheel & Clutch - last one you will buy!
Posted: Fri Feb 26, 2016 8:20 pm
How many of you have had the pleasure of changing a clutch in the Roadster? Oh boy, time to pull the engine...
Back in the late 90's I started using 240z clutches with the U20 because with a souped up U and hard driving, it is pretty easy to wipe out a stock clutch-cheap 510 clutches don't stand a chance and most oem Nissan clutches didn't survive past about 80k miles-that speaks volumes.
I realized that for most street roadsters, a 240 clutch could potentially be the ONLY clutch you would ever have to install. The one minor downside to the larger clutch is almost exactly one pound of additional weight. so lightening the steel FW was the solution back in the day. It worked, and it worked really well.
Now available is possibly the best Flywheel and Clutch option for any roadster with a U, R or H/Stroker engine:
New 11 lb Aluminum Flywheel with a hardened steel wear surface and machined for the 240 plate. You can use any decent 240Z clutch and forget about it. A Dakin/Exedy plate is perfect and cost less than 1/2 the price of a 2000 clutch if you shop around.
With the HD 240 plate, the assembly only weighs 22lbs, which is about 9 lbs lighter than the OEM clutch and FW. Most importantly, the 240 disc has !40%! increased surface area which equates to a 40% increase in torque capacity and terrifically improved wear characteristics.
The weight distribution for the 240 clutch is on a 1" larger diameter surface, which makes the moment of inertia higher. This means the flywheel with the 240 plate will feel a little heavier than it would with a stock clutch. The best way to think of it is the same or better performance to a very light steel FW, but not as light as a full on racing FW.
So here you have a lightened assembly that is not SO light that it difficult/annoying to drive on the street, and an ALMOST INDESTRUCTIBLE clutch with no real weight penalty - (basically the same as a radically lightened stock FW and factory plate).
Since the release levers on the 240 plate are a little longer, there is no increase in pedal effort with the substantial increase in torque capacity. You also use the commonly available 240z throw-out bearing.
You could even race with this unit since kevlar/composite 240z racing discs are available. This would also be awesome for vintage racing etc, where you aren't planning on removing the engine very often.
I HAVE NEVER HAD TO REPLACE A 240 CLUTCH THAT WAS INSTALLED ON A ROADSTER - The same clutch was also used in 2400cc trucks, so you know it is pretty rugged.
Don't waste your money on an expensive 2L clutch that WILL ultimately wear out! I haven't bought a stock roadster clutch in probably 20 years...put one of these in and forget about it.
USA/CNC quality part. (No China parts here!!)
Intro price 450 (Flywheel only) and limited availability.
If you plan on keeping your Datsun a long time/will stay in the family - this is for you...
