Turbo has been rebuilt and is on its way back. My flywheel is way too thick and thats what is causing all my clutch problems. I have that off and will drop it off to get machined. Once that is done, I need to decide if I am gonna swap the cam or not. Slow but steady.

What thickness is your flywheel now, and what are you machining it down to?

Figured. It looked too think from the pictures in another thread.

Oh its way off. I took some measurements and pics and emailed them to a very helpful PFF member. He did the calculations and here is what he found:

The top measurement is 1.157" and the bottom one is 1.124", so the crankshaft flange sticks out past the bell housing face by 0.033".

So to end up with the flywheel clutch face at .830" from the bellhousing, the flywheel needs to be .797"

Or take 1.157 - .830 = the amount to remove from the flywheel = 0.327"

Your current flywheel is 1.124" so removing 0.327" = 0.797"

You should be able to target .800 to .810" for the thickness of the flywheel and be fine.

Its always better to have too much flywheel height. Justin started running the .840 to allow for later resurfaces and to help the slave cyl / HTOB be happier.

Engine is on the engine stand, car is in a million pieces. I have a new trans ordered that Scott (DH) located for me. Found a broken valve spring. Odd, since they are brand new LS7 springs. Making some new fuel lines right now. I never liked the old ones.

I am almost done putting Garths LQ1 swapped Fiero. Its got to go to the exhaust shop, alignment shop and I have to install some fuel lines. I'll be hauling it to Virginia on the 9th of July. When I get back, I'll get back to work on my 88. AFTER, I clean and organize my nasty garage.

New cam, 130# springs, retainers, locks, seals, double roller, LS7 lifters, gaskets, 60# injectors (all from Intense Racing) and replacement F23 were ordered yesterday. I have to pull the heads and have the spring pockets machined 60 thousands for the new springs. I also got a CC pushrod length checker as well. Pretty much positive I will need custom length PR's. I also have to weld in a 2" flex joint into the crossover pipe.

Goal is to be up and running by Oct 1st. Set back and watch as I roll the dice, one more, one last time.

I'll come and get it if you want to donate it to a good cause.
