1.8 clutch for a 1.6
I was just wondering if i was the only one running a 1.8 ltr clutch and flywheel on my 1.6? If so whats your setup?
My setup: 1991 1.6: 1.8 ltr ACT lightened flywheel and full face clutch. |
I'm running a 1.8 Fidanza with RPS Sport and 6 puck sprung on a 1991. Holds great, but in reverse it grabs and clangs until it locks up. Also have the Fidanza "buzz" when decelerating with engine braking hard.

Nope, folks have been doing that for years. I've got a 1.8L Spect Stg. 2 on a lightened shaved 1.8L flywheel.

This topic goes on monthly at m.net. You might know all this already, but allow me elaborate for those who don't.
The 1.8 clutches at each stage will hold a little more than the 1.6's... but at the expense of weight. The 1.8 StageX clutch is dimensionally a little bigger and weighs more than the 1.6... and the stock flywheel weighs more. I don't know exactly how much. It can't be more than a pound or two. But when the idea is to go lighter (for better spool in turbo cars), every pound counts. In fact, a lot of 1.8 guys will drop in 1.6 setups to shave a few pounds. Shaving a 1.8 flywheel like Bripab did is recommended if you're going that route. Unless you're on the edge of power for a particular 1.6 clutch, the 1.8 is nice, but not necessary. For example, the Spec Stage 2 1.6 holds 239ftlbs, the 1.8 holds 275ftlbs. If you've only got a 160ftlb motor, why pay more and go heavier with the 1.8? But if you've got a 235ftlb motor, the 1.8 might makes sense as you've got a little more headroom for growth or abuse... should still have it shaved. I got somebody at m.net to give me a 1.6 stock flywheel for free (just cost me shipping). A shave job might be $80-$100... still less $$ than to purhcase a lightweight aftermarket model. But now I don't have to wait a day or two while my flywheel gets resurfaced and the car is up on jacks. It's ready to go in a soon as the old one comes out. I think the real advantage to going w/a 1.8clutch would be with a stock motor. I've been able to slip my stock 1.6 clutch since new. A free flywheel and a $100 1.8 economy kit from Rosenthal with a little extra clamping power would be a nice upgrade. Again, just info for others... |
