Post Clutch+Flywheel Install

Well, today our guru, Mr. Kartboy and I installed an ACT Street Clutch and Primitive Lightened Flywheel. The installation took us about ~4.5 hours in my driveway with 4 jacksands and a floor jack. The install is overall not that hard. The hardest part is to get the #@$^!!! tranny back into its place. The rest is basically getting the stuff out of the way of the tranny. Here is a small short description on the job.

Drop exhaust, heatsheild and drivesahft. Pop the ball joints, get the front axles out. Get all the wiring out of the way. Drop the tranny. Install clutch. Put all back together.

Me and Josh will be installing the same setuo in his car in a week or so and I will do a detailed pictorized how-to. I stongly feel that anyone with average wrenching knowlegde can do it with a help of a friend.

So far, the car runs good. The rev are much quicker and no idle or moving problems. I have to wait until the disk wears in (500 miles) then I will start abusing it and let you guys know how good it really works.

Tom, thanks again.

Thats cool,

I have my ACT clutch, kartboy shifter, cusco shifter bushing, sti tranny and engine mounts sitting at home. I have it from PE that my flywheel is shipping. So we are basically doing the same setup, please let me know how it goes.

I think Im going to get my dealer to do the work for me, but if he is to expensive Im going to Dallas to have Cobb doing it.

Keep us posted.

It looks like I will be doing a clutch swap in the near future. The more details you can posts, with pictures, the better. I don't consider myself mechanically inclined, but situations have forced me to consider the possibility.

I've done pistons and rings on a modern, 4-stroke, high revving motorcycle, plus numerous rejetting jobs, an engine swap on a 84 Toyota Supra, and a couple other things here and there.

So, if I can hit with a big enough hammer, I'm game to try it!

Is anyone bothering to install a scattershield with the lightened flywheel? Is a scattershield worth the cost and effort?

I dont think you need one with a 16 pound flywheel.

I got a UPS slip that says they left it with the apt managers. I cant wait to see it and have all my parts ready to go.

I've recently seen proof that a lightened stock cast flywheel can be a dangerous route. A friend of mine has/had a 11 second Galant VR4 built by TurboTrix and it carries some RalliSpec parts aboard. He had a ACT lighten stock flywheel that exploded while driving on the street. In the process, it took out the bell housing, tranny, alloy radiator, front crossmember, buckled the hood, crushed a stainless steel intercooler pipe and sheared the thermostat housing right of the head. Ouch!!

This seems to prove my fear of machining down a cast flywheel. Normally, the grain structure of rough cast is continueous even at the surface ( like a hem on cloth, preventing it from coming apart). When you machine it down, the metal grain in the lightened areas are interrupted and prone to coming apart ( like a frayed edge on clothing).

Interestingly, another customer using a lightened stock unit asked me about the possiblity of make a scatter shield.

My $.02

personally installing this clutch and flywheel. it is by no means fragile. it looks like they did their homework to make it very strong. it should hold up to the abuse from the "weekend warrior" for a long time.

just my two bushings

I wonder if having cryogenics (sp) perform their process on the flywheel would be worthwhile. If it makes brake rotors last twice as long, I imagine it would help this kind of application. I certainly dont want to put a bomb in my car. (I dont think primitives flywheel is a bomb and he is using one in his rally car like imprezer said)

any thoughts,

ps Rallispec how much for a scatter sheild? Its probably a good idea.
