Im putting a big Garrett on my 1hz but it looks like that waste Gate is going to hit the engine block, has anyone come across this before? And what have they done?

Ok, mine is a gt32/76, that's what I'm needing to know on how to do the waste gate side of things, do you have any pics of yours?

It depends entirely on what manifold/adapters you use.

I used a DTS manifold and a 2 piece adapter, this brought the turbo just far enough away from the block and engine mount to need minimal waste gate actuator modifications.

Here is an old pic of mine, a GT2876r. Even the 4" inlet clears the engine mount easy.

hey, what did you guys do to your engine to stop the over heating in the pistons and the head? i just droped compression in my third piston, to pull the engine down and find 5 out of 6 pistons cracked, one fully in half, and the bottom of the head with cracks all through it. its a 1hz with a safari turbo kit. im planning on rebuilding the motor and trying again with the turbo, got any ideas what to do to help from this happening again?
