I've got a 1998 Jetta with just over 200k and some pretty serious driveline clatter, so I'll be pulling them out and replacing shortly.
In addition my clutch has had a slip for quite some time now, so I thought this would be a good time to take care of that as well.
A couple of questions before I tackle the project:
Each time I work on part of this car, I try to upgrade and leave things better than stock and get some more longevity and performance out of the car. I was looking at Single Mass Flywheel and a Stage 2 clutch.
At some point I want to put in a Malone Stage 2 tune and Bosio Injector nozzles but that is a little ways off. But I want a clutch that will handle that torque when I do it.
- What is the advantage of a single mass flywheel?
- I notice they make the flywheels in differing weights, what is the advantage of lighter or heavier and how does it affect performance or fuel mileage?
I'm planning to replace/upgrade the clutch, drivelines, wheel bearings... Is there anything else I should consider tearing into while I have all this apart? Engine mounts were done less than a year ago.
- Also, while the tranny is out, I am considering installing a higher ratio 5th gear. Have any of you guys done that, and were you happy you did? ID parts has a .658 and a .717 ratio set. What do you guys recommend? Is this a job that will be overwhelming for me? I am fairly adept working on these cars and do all my own service work, but have not done much inside a transmission before...
We take this car on some pretty long road trips several time a year, sometimes 5,000+ miles and my main goal would be to lower RPMs at 65-75 mph to increase fuel economy. The car is a daily driver as well, so I wouldn't want it to struggle at 50-55 though. Thoughts?
Whats the best viscosity/brand of oil to run in the manual transmission on this car? I've seen a lot of Redline brand mentioned, is that the best and if so, what viscosity?
Also, just have to say, two thumbs up to this forum in a major way. The level of info available from you guys for these cars is absolutely unparalleled. I've been doing some upgrade/custom work on my ford pickup over the past couple months and can never get as helpful and reliable advice on other forums as I do here. The TDI community is second to none, hope y'all know that!!
