Re: Stock Flywheel vs. Fidanza Aluminum for Turbo L20B
The Roadster weighs about 2,000 pounds, so that helps a lot. From what I understand a 510 weights 2050lbs to the roadster’s 1983lbs I doubt that 70lbs would make that big a difference ? And N/A so there is that too. With the turbo you would have more torque down low which would theoretically make i...

So you had a stock L20B truck flywheel lightened to 17lbs?

Re: Stock Flywheel vs. Fidanza Aluminum for Turbo L20B
When I bought this motor, the guy I got it from said that it came from a 1980 Datsun 720 pickup which belonged to a guy who was a sales rep for CarTech. This was a demo truck that was used to show performance shops their turbo setups. So the flywheel is likely a stock 720 pickup L20B flywheel.

Re: Stock Flywheel vs. Fidanza Aluminum for Turbo L20B
Thanks to everyone for their input.
I think I will start out with the stock flywheel and see how I like it. If I later decide I want it to rev faster, I can buy a clutch kit and change out the flywheel.

Re: Stock Flywheel vs. Fidanza Aluminum for Turbo L20B
Preference, yup you can never say for sure what someone else will prefer. This is why I mentioned age as a rule for selecting just how much you might be comfortable with. It's a sliding scale and the younger you are the more you put up with irritation, discomfort and doing things the hard way. If o...

Re: Stock Flywheel vs. Fidanza Aluminum for Turbo L20B
A lot of 'racing' things just don't work on daily driven street cars.... I'm older and like to enjoy driving. Mike - I would agree with you much of the time on this statement. It boils down to preference, really. David, I would also agree that Keith has the right balance at a 17 lbs - it's right in...

Re: Stock Flywheel vs. Fidanza Aluminum for Turbo L20B
It has been a long time since I have seen one of the old draw through systems, very cool. 5-7 lbs will be just great on a stock motor. My original permutation of my kit, was for a stock engine and the first 5 lbs got the job done well. Bonus round back in the "old" days was our pump premi...

Re: Stock Flywheel vs. Fidanza Aluminum for Turbo L20B
Flywheels store kinetic energy that can be used to get a heavy car off the line and moving. A lightened wheel will need to be spun faster to store the same energy, there's no way around this. This energy is not wasted and is returned when you let off the gas to slow down. A lighter wheel will slow ...

Re: Stock Flywheel vs. Fidanza Aluminum for Turbo L20B
What are the weight of your two flywheels Dave? I would probably go for smaller diameter and lighter myself for first try, mainly to aid spool-up. I don't think the lighter will affect cruising inertia. The Fidanza flywheel is 10 pounds. The stock is 28 pounds. I’ll be running an Exedy OEM replacem...

Re: Stock Flywheel vs. Fidanza Aluminum for Turbo L20B
Either is fine. Stock L20B is about 93 hp so 7 PSI boost is (theoretically) about 50% increase. So just under 140 hp. A 225mm will hold that and so will the 240mm. 225mm pressure plate. All 550 kilogram clamping force. '79-'83 280zx non turbo coupe.... 30210-N4210 74-78 620 and 80-82 720.......... ...

Stock Flywheel vs. Fidanza Aluminum for Turbo L20B
Hi everyone, It has been a while since I have been on here. Did you miss me? Lol. I have an old school L20B CarTech Turbo that will be going into my 510. It will use a Weber 38/38 carb. It will be backed by a dogleg 5 speed. It will be used as a street car. This setup will replace my stock L20B with...

Re: Oval gasket in Trunk for Fuel Lines
Ten years plus! Bringing this back from the dead to see if anyone has found a particular plug for this more recently. The original ebay link is understandably an error now. The old auto rubber part numbers above look to be still available, but they are really too small. I measure the hole at 30 x 5...
