Yea weisco's older style were cracking around the skirt, know of 2 blokes back in n.z had it happen but from what I can gather they fixed the issue a couple of years back
I had issues with weisco pistons
this is just my opinion I'm not bagging them and it was part my fault and part the dealer in the usa , first issues with the crowns collapsing with not even the slightest bit detonation or pitting visible might hve been the one offset wrist pin causing both issues
not a big fan of the ring support for the oil ring on the stroker pistons.
lol I realized they had sold me E8 pistons when I referenced the part no later , they did mention they only had this 0.40 piston for the 100mm crank set up ( running longer rod )
I assumed they would send the correct piston, and I was very specific with year and model of engine, having said that I am 100% responsible as the engine builder thank god it wasn't a customers engine.
problem being weisico run a offset pin to reduce piston slap but what happens when the crankshaft rotates the other way , causing Induced piston slap sll the way up to rev limit 8500 rpm, I was lucky that no major damage occurred
I should have been more thorough, but I didn't click until later on
oh well shit happens just thought i would share that and maybe save someone the grief , now running cp no offset pin seem ok but the nitrous will be the test
Should be ready for the next WRX round at PI in a few weeks.
