I now need new pistons ! Because the guy at the machine shop Honed my block wrong and well I need a oversized piston to compasate for the scoring from when it previously overheated in the past so in order to keep this block I need over sized m20 b25 pistons
Or any setup I can run using a stock 2.5 crank someone help me out any one have these

[e30m20TurbO7]

Now I am Using a completely different block

[e30m20TurbO7]

just found out none of the cylinders are round and the honing was absolutely pathetic
soo i started over again

That sucks man hope things turn out better for you in the long run

I picked Itu up from turbo325ii Brett today for 100 bucks
Spent 2 1/2 hours dissassambleig and cleaning it today
Getting it ready for its new internals
An it's paint job and hone

Sorry to hear about the block. Hopefully you found a better machine shop this time around.

[e30m20TurbO7]

It's a bummer lots of money waste at that shop but I just saved by doing the work my self but it all changed my route btw I read your build thread all the time
Love 2002 's

Take 2



Pistons got cleaned up
As well as the rings for put back on
And I'm cleaning all the carbon of the valves



I got one of the valve guides out with a tap

are you going to reuse the same seals on the pistons? and what are you using to clean up the pistons? thanks!

[e30m20TurbO7]

im reusing the same rings / as much as i dont want to i feel like bmw has a high qaulity enough ring to do it
i just use a little pic to pick out all of the grooves and scotch brite simple grean and carb cleaner mainly just elbow grease with a lot of fine motor skills

are you going to reuse the same seals on the pistons? and what are you using to clean up the pistons? thanks!
