im not really worried about the n/a drivetrain crapping itself for the first couple races it sees, but im more worried that they really dont make a decent roadracing clutch and flywheel combo for the na drivetrain (maybe i just havent researched it enough) if i get a TII drivetrain, it can easily handle all the stress, and i can get a good racing clutch. so what do you guys think? (experiences, advise, etc.)

 

you dont really need much of a clutch to roadrace, and flywheels arent class legal for much. if you're in a modified class, then the t2 stuff should last longer

 

this will be used to drift in, so...i believe i will just wait and see how long my na tranny holds up.

 

Stronger rear end, axles, driveshaft, transmission, and clutch fork...
Larger clutch disc...

If you want stronger, isn't it obvious?

If we're talking drifting, there isn't any really strong load on the car, unless you crash or you're popping the clutch like a jackrabbit on steroids.  The NA drivetrain should be fine, as long as you don't do anything unnecessary.

There are plenty of extreme clutches available for a n/a FC. Clutchmasters, ATC, Centerforce all make race worthy clutches that will handle any amount of power a n/a can put out. Tilton even makes a multi disc clutch if you want to spend some serious money.

There are many places that sells <12lb flywheels for the n/a, (SRMotorsports, MazdaTrix, RacingBeat, etc)

In road racing with a non turbo you really don't need the extra strength or weight of the T2 driveline. Take a look at SCCA's ITS road racing class. All FC's are required to use a non turbo driveline. Transmision and rear end failures do happen but almost always due to old age (aka: bearing failure).

If you want strength of the entire driveline it might be worth swapping over to the T2 driveline. But if a clutch is all you are worried about there are plenty of options with less expense and less labor.

 

well i have done some more in-depth research, and i can get the clutch i want and keep the na stuff. i suppose if scca requires to keep the N/a driveline, ill keep it indefinately

 

If you are building a race car for a specific class of racing (I gave ITS as an example) you probably need to back up and start with getting a rule book. Other SCCA classes that the FC falls in may allow drastic drivetrain modifications (F-Production, GT2, GT3, etc.).
