    Electrolysis nickel plated exhaust manifold

    Basically - yes. Companies call it different things as a marketing tool. The boron content varies somewhat - that also affects the hardness.

    Electrolysis nickel plated exhaust manifold

    Electrolysis nickel bonds at the atomic level - it's not a coating - nickel adheres quite well to cast iron and steel. If the plating shop used the same thickness as they do for corrosion, it should be plated on at a 0.001" (1 thou) thickness minimum. Like Grim said, it should easily withstand...

    The (old) Official Gun Thread.

    I practice shooting a 3" circle. Start at 15' - when you can put all the bullets in a magazine inside the circle at that range, move the target to 20'. Repeat as necessary to get the range out to 35' - 40'. Practice shooting 2 shot drills - one at chest center mass, one right between the...

    Does anyone use Toyota Brand motor oil in their Supra?

    There's a reason you don't see it discussed much ;) Way over priced for what it is - there are better alternatives available for less $$$ - this is not opinion either. If you are going to pay that much for a quart of oil, buy Red Line and get the best there is. Or, you could buy Castrol...

    Coolant filter pics

    Do not use that filter - it's purpose is very different that what you want to do. Use a Wix 24059 http://www.wixfilters.com/filterlookup/ResultsPart.asp?PartNo=24069 -Or- A Wix 24070 http://www.wixfilters.com/filterlookup/ResultsPart.asp?PartNo=24070 Both have the correct thread to fit that...

    Need Arp head stud socket help!

    Unless you have ARP stud nuts > 4-5 years old, a 14mm should fit the nut. A Craftsman 3/8" drive 12 pt 14mm socket fits current production ARP stud nuts and will clear the hole in the head. Use a 1/2" ---> 3/8" adapter to mate to a 1/2" drive torque wrench..

    To run ISCV or not?

    No -the air valve IJ speaks of is the power steering idle-up. It's purpose is to increase RPM during idle/low speed, full deflection turns. PPS is controlled by a solenoid to decrease steering response at high speed.

    ARP head bolt tool????

    Yeah - It's the same thing that mechanics try to make out concerning motor oil. Myth, after myth, after myth gets passed along word of mouth until somehow it becomes fact...BS just keeps building on itself. Problem is it's never backed up with any data - the "experts" always just "shake my...

    ARP head bolt tool????

    You are confusing torsional deflection (the angular deflection of a torsion shaft) with the amount of force (torque) applied at the bolt. Torsional deflection of solid shaft can be expressed as: θ = 32 L T / (G π D4) where: θ = angular shaft deflection (radians) L =...

    front main seal

    In addition to the main seal, replace: Oil pump drive shaft seal Cam seals (as mentioned) Might as well while you are there.

    ARP head bolt tool????

    Don't know who told you this, but is is way wrong. A straight extension on a socket does not have a significant effect on setting torque. I'm glad you posted this disclaimer. Here's why: ARP bolts are limited to 75 ft/lbs on an aluminum head due to the difference in heat expansion for...

    Synthetic oil in the 7M???

    The base stock is not the same - synthetic oils (the true ones) use PAO or ester as base stock. Many on the market say "synthetic" but in reality use an extensively hydrocracked mineral oil. The additives are similar, but are formulated for the base stock. Not necessarily more - take...

    Shim oil pump or not?

    You should be ok - the spring will start to bind at ~11mm. 5mm is still plenty ;)
