Brodie,

I would recommend O-ringing the block, too, to prevent (hopefully) head gasket failures. It's a lot of work, but will give you some peace of mind, and maybe prevent headaches, down the road.

Bill, in Conway, Arkansas
Just something to consider. When I first did my turbo (1979), I had tuning problems. Went into detonation a lot. Would blow head gasket.
So instead of correcting the detonation problem (cause) , I "O" ringed the block and used a copper head gasket (symptom). Cured the head gasket problem, and started eating pistons. I would have been better off not "O" ringing the block, and letting the stock head gasket act as a "fuse" (blow the gasket instead of pistons), untill I got the tuning right. At 10 PSI, I don't feel "O" rings are required (if the tune is right).

Post subject:  Low boost...
Charlie.

Thanks a lot for the tutorial! Like I said, I am just a newbie at this and am in no way, qualified to give advice. I was thinking about the possibility of him running 15 pounds of boost, down the road, which he had said he might try,

I agree, 10 pounds is not really enough boost to require O-Rings, if that's all he runs.

Thanks again!!!

Bill

I can always try out 10psi and see how I like it. If I think I would wanna go to 15psi, I could always run the 10psi in the motor and build the engine that the turbo engine replaced.

Boost is like drugs...once you have a taste you want more. There is no going back once you try 15 psi.

I agree. All power adders are addictive. Turo or nitrous.
And tuning is much easier now, then when I did mine. In '79 it was hard to get any turbo info. No such thing as electronic timing control. No wide bad O2 sensor. All I had was an EGT gauge from an airplane, and my ear. Was about impossible to hear detonation, at WOT.
I did have water/alcohol injection. A windshield washer pump, and nozzles that turned on with a pressure switch at 5 psi and sprayed right down the carb barrels. (draw thru system)
