    Yep, both 76g Heavier rockers would likely just add a little parasitic loss. Stiffer valve springs would be more likely to increase wear

    So we're getting together on the 28th for beer and exhaust cutting of epic proportions.  I'm bringing a welder and grinder and possibly a growler or two.

    CMart said: I like the claw hammer idea. These are reverse thread correct? Correct.  I tried holding the pulley with everything I could think of from screwdriver, pry bar, crow bar, etc and actually bent one of the screws holding the pulley on with the pry bar.  I took a small claw hammer that I had and wedged the claw end in and voila!  Nut was off.

    Yellow Lamin-X is the way to go since it also helps protect the glass from rock chips

    I like to take the front end off for easier access to things on the front of the engine, when you don't need to flush the cooling system and such. You could make it come off with a couple of pins, so it would be uber quick on the track to do some fixin' without absolutely having to take the radiator off every time. But, when you want to, its just a bolt or two, and a couple hoses to do so.  preference though!  Its a ford 9" e30 with a borg warner turbo and e85 and a t56, I bet you can find it on google

    Does the high idle happen all of the time? I had a high intermittent idle when the engine was warmed up due to a loose connection for the ecu engine temp sensor, it thought the engine was cold and tried to compensate. Sent from my potato phone

    Thanks all. Found a pump like the ones a few of you mentioned at Auto Zone. Now to pick up some fluid, and then make sure I can get the two plugs out before I start.

    Wait are these rear trailing arms, or rear subframe bushings? Lol. I feel like the rtabs are pretty small. Like 1.5" od or less.  Man I lied. I was going to build these, but I thought they were the same as the e30. I need e30 rear subframe bushing and rear trailing arm bushings. Anyone want to measure some? I have a rear subframe I guess I could measure? Paying 300$ for 30$ worth of delrin is crazy talk to me.
