The static compression is lower.The 4g head is 47cc, and the evo is 43ccAlso notice how much lower the piston is in the block.

Here you gohttp://www.dsmtuners.com/threads/how-to-plug-crank-oil-galleys-after-ball-removal.473543/

I have a welder that I take the cranks to, He gets them out for me.Then I tap and plug the galleys closed.The factory drills the galleys from the rod throw to the main journal. It is the passage to allow oil to the rod bearing.

I have no clue, never tried with a MIG...

Why ask?They told you what they will tell you.Now you need to find a shop that will fill your needs.

What JAM Tony said.Its not a small block, so they basically do not what to do it.Cutting the main caps is not much more difficult than cutting the caps on a SBC.Short of the block being busted into 2 pieces, it can be machined and fixed by a shop that has the knowledge and experience.

They do.. then shrink when they cool, so the ball ends up smaller than when they started.I have no clue if there is a vid or not. I never made one.I have done about 300 cranks like this, so it works. Not just 4g63 & 64 cranks, But Honda B & D cranks, Nissan RB 25 & 26, SR20, KA24Along...

You hit them with a tig to shrink the balls, then build up a pull point with weld and pull them out with plyers

Now your cas slot will be off too...

What cam gears are you running? the Evo or the 7 bolt?IIRC the cam alignment dowels are drilled in a different spot on the Evo VIII cams than a DSMSo you end up having to make your own timing marks for the cam gears.But the Evo VIII cams are not a drop and go.Also did you bleed down your...

If you have a 7 bolt crank with 6 bolt rods1) you need 7 bolt bearings 2) make sure you have enough rod side clearance.6 bolt rods are wider at the big end and have to be machined down to fit on a 7 bolt crank properly.

Its a waste hanging forged pistons on stock rods, 6 bolt or otherwise,With a 20g and decent tune, the NPR 63DT will support that.The reason the other 3 cylinders could be low , is bigger cams and/or the timing belt off a tooth.At 84k miles, The timing belt was changed once.Pull the...

A leak don needs to be run... it could be a slight bent valve in #2 causing low compression.

That all depends on how tight of a spec they use.Some shops are good with a 1g +/- of mean weight (up to 2g from highest to lowest) Most pistons fall in this. Others use a a .5g, So 1g high to low, Most the time forged pistons will fall into this.Few go as tight as .1g or .2g from high to...

Jam Is up your way, Down in Md.If you want a shop that knows DSM blocks, good chance you will have to ship it out
