So here in the next few weeks I have a good bit of work planned out to do to the car and I was wondering if I could get some opinions on how to go about it. I will be installing a new timing belt along with a waterpump all new pulleys and a balance shaft delete, delta regrind 272s, cam gears if they are necessary, new lifters, new valve springs, motor mounts and trans mounts, new front end bushings, and a new transmission, and a new clutch. Now my question is would it be easier to do all of this in steps or just pull the motor and trans out at once and do it all with the engine removed? Would it be less overall work to go about it that way or would it be easier to just do the trans one weekend then the cams/timing components the next? Any input is appreciated. Also I will be doing my own clutch and replacing the flywheel plate this time around so how do I step it? This is my first go around with a clutch so I dont know about stepping or what it even is.

The step height should be .610-.612 if you're using an ACT or factory clutch. Follow the step recommendations from the clutch manufacturer if you go with anything crazy. It's a measurement of the gap between the fingers around the edge of the flywheel where the pressure plate bolts up and the friction surface. The pressure plate takes up some of that space and the step height measurement is critical to allow just enough room for the clutch disc so it can disengage enough to do its job, and for achieving proper clamping force across the face of the clutch surfaces when spring pressure is released.

A thousandth or two makes a difference you can feel in the pedal, but the clutch manufacturers dictate what to use. The problem with getting it wrong is it will be out-of-whack at one extreme or the other. Engagement/disengagement problems or slipping. Take your pick. Get it right the first time or do it twice. .610-.612 works great for ACT and stock clutches. Always has for me anyway.

Thank you very much I have been wondering what it was. Any way that I can check it? Or does it have to be machined for certain?

Now that you mention the issues it can cause maybe this has been my clutch issue all along as i doubt the shop i used to take it to even bothered with stepping or knew what is was.
