This is honestly more of a rant post than anything else bc I'm ****ing pissed. I'm currently building a k24/20 motor with forged internals. I purchased Wiseco's 87.5mm 10.2 compression k24/20 piston kit. I took my block to a machine shop to get it bored out to 87.5mm, with .0025" of piston to wall clearance as specified in Wiseco's spec sheet.
I started gapping my piston rings after I got it back from the shop, 1st rings went fine, I needed to gap them to a little over .017", and all the rings came out of the box with a gap of .011-.012", which is plenty small enough to start gapping with.
Then I got to the 2nd rings, I need a gap of .019" (as specified by Wiseco's spec sheet that came with the pistons). ALL of the rings were too big, ranging from .021" to .025" gaps. I was pretty pissed, and it also happened last Friday past 5PM, after Wiseco's offices had closed for the weekend. So Monday I called them up, explained my situation, and the rep said that the specs in the spec sheet are technically minimums, so if they were at like .021" it would be fine, but that .025" was definitely too big, and he'd send a new piston ring kit out to me free of charge. I was still a little upset bc my engine build was delayed by another week now, and I currently don't have a car to drive, but thankful that they seemed to resolve it so easily.
Well today I finally get the new piston ring set, and it's the same goddamn ****. 021" to .025" out of the box gaps. Wiseco's offices have also closed again, so now I have to wait until Monday to call again. I guess I'll just ask for them to send me an 88mm ring kit this time around? I honestly have no ****ing idea why this is happening. Like before I decided to bore my block out and go with Wiseco pistons, I ordered some eBay piston rings, and all the gaps were perfect, but a supposedly reputable brand can't do the same thing???
Has anyone else had any problems like this with Wisecos? At this point I really really wish I hadn't decided to go forged internals, really feels like so much more time and money than it's worth. Ugh.
