I have an 04 Coupe 6MT, just got my Z1 Crank Pulley. Just tried the breaker bar at 5 o'clock and turn the engine over. Three tries and car lifts up momentarily but bolt isn't breaking free. The only thing I can think is that my battery is weak cause I left some sound activated LEDs on a few nights ago. I just threw my battery on a charger for now and was going to try again in a few hours. If charging the battery doesn't do the trick what does everyone recommend. Just the breaker with a 3 foot cheater? How do I get the crankshaft from moving as well?

 

Well figured it out on my own, put the car in 6th gear and used a pipe wedged against the seat to hold the brake down while I used a 2ft pipe on a breaker bar. Car is definitely more responsive, small increase in tq and hp throughout entire power band. Unfortunately the metal tabs that hold the bolt for the pulley tensioner broke so I had to use a jack and a piece of pipe to hold the tension while I tightened the 14mm bolt that holds the pulley in place. Besides that everything else went smoothly, definitely recommend Z1's products.

 

For the future use an impact wrench to loosen the bolt, only takes about 5 clicks and it pops right off. Muuuuuch easier.

 

Impacts ftw. Makes life easier
