Hi.
I am about to start tearing down the engine for my GT6 Convertible project and
I am using a GT6 2.0 engine.
I wonder if there is some wisdom here for the following questions?
1- I have been reading about the infamous crank thrust bearing in the Triumph 4
and 6 cylinder engines. It seems to me the stuck unit is a steel 180 deg unit
that has a thin copper plating that wears, then can damage the crank by steel
to steel contact or by falling off altogether.
So I have read of 3 options: Use a copper alloy replacement (no steel), use a
copper alloy, 360 degree replacement (needs some machining of the block), pin
the bearing, or use another carâ??s main bearing that has built in thrust
surfaces (machining of block and cap needed).
Since I am hopping up the engine a bit for street use, which do you guys
recommend?
2- I plan on hopping up the engine to roughly 120-130 HP. I understand a mild
cam upgrade, some head match porting and balancing along with a compression
increase should do it. Any recommendations? I think I will keep the stock
intake and exhaust manifolds and Strombergs, maybe add a free flowing exhaust.
Is that enough? Would adding triple 150 strombergs too much? Or a pair of 175
Strombergs?
3- Does anyone on this list know of a good Michigan located place I can take my
block, head and crank to get cleaned up, machined as needed, etc? I plan on
doing the assembly and disassembly, but not any machining myself.
Thanks!!
