So Fiero...any updates?
Alright, thanks for the clarification. Not going to lie I'm nervous to put this block together as its my first time. Trying to convince myself to save $250 by assembling it myself, but its a hard choice because the machinist has done it alot more. This thread is very helpful and has alot of good info, so it give me hope.I usually snug the mains, pry it back and forth, torque the mains and pry it to one end and check the thrust.
What do you use to measure?It is not hard to assemble the engine as that is the easy part. The hard part is knowing how to use proper measuring devices to be absolutely certain you have your clearances within specifications.
I personally just built a Evo VIII motor Wednesday, Put it in the car thursday and with the engine having about 5 miles on it breaking it in just made 862AWHP at 42 PSI.
Finding a set of clearances that work is the hard part because unless you have someone that is already knowledgeable on 4g63's and can tell you what clearances should be used for x amount of HP then most people have no clue what to do.
You may ask what clearance's am I running for a 900whp 4G63?
.0025" Main bearing oil clearance
.0035" Rod bearing oil clearance
I am running a much larger rod bearing clearance due to the fact that I am running aluminum rod's. Clearance for steel rods will be .001" smaller in most cases.
I only use Brad Penn 20w-50 and it gets changed after every track event.
Forgot all about this thread. I only use Dial bore gauges and Micrometers.What do you use to measure?
Also, great point about oil clearance. Normally, the manufacturer of the internals has the specs so the assembler doesnt always need to blow up a couple motors before he/she figures it out.
