Original Explosive Material - Tobes' Build Thread

[loc182]

They say always leave them wanting more, so this will be a slow build thread

The Supra has run well since 2013 despite my rushing into things, largely thanks to many posts on this forum. However, something has felt off for a while and it looks like my luck has finally run out:



Machine shop will get the head once I can find one in the Columbus, Ohio area to do cleaning and timeserts on the exhaust studs that came out. I have my own cleaning to do as well on everything else.

The temporary goal is to get the Supra running again with a stock gasket, and wait for warmer weather to pull the engine to get it prepped for metal and ARP studs.

Massive thanks to Jeff and everyone involved in bringing Supramania back, I am very thankful to have this wealth of knowledge and Cygnus-X1 as aids in this rebuild.

Unless your power goal is above 350hp, a Felpro head gasket with ARP's at 75ftlbs will last forever.

Head is back with time-serts and the OEM exhaust studs I bought in 2013 are finally out of the package and living their best life!

Got some cleaning to do, but I can finally start getting ready to reassemble.

Is that 75 with using their lube? I have the undercut head studs because I heard they are better with a composite gasket (mine is Ishino Stone, looks like an OEM). The instructions say 90, but so many threads say 80.

What is the best thing to do?

If ARP says 90, then go with that, using their moly lube. I said 75lbs, because I thought you were using ARP head bolts, not studs.

Cleaned up the head today and finally installed the EGR cooler gasket and bolts I bought in 2013. I foolishly thought I could change that with the head in the car.

However, I did manage to change that water union and banjo pipe with the head in the car in 2013. It really thought it was never going to come loose and the original union looked terrible. The new one still looked pretty good, but a new set was cheap and my oh my is it so easy with the head on a bench

Valve cover No 3 still looked and felt alright after cleaning, so I decided to give it another go instead of using the NAPA drain plug gaskets. I did torque those plugs to 26 though at a recommendation. When I took them off originally it took a breaker bar and all my strength and nearly broke my new at the time 14mm Allen socket. I wonder if the TSRM value of 13 ft-lbs is just for the bolt that sits in the last plug and they left out the true torque for the plugs? All four of mine were loose when I started pulling the car apart this time.



Tomorrow I should be able to put the head back on and begin getting the car back together!
