Nothing new since last post other than several emails asking for changes into thread subject and tag words. Haven't had time to do anything with those rods. This thread is hurting their business according to emails. First of I can't change almost year old #1 message and AFAIK don't have any control over tags associated with this thread anyway. In any case I'm not going to waste moderators time by asking them to do changes. If this was just one isolated problem maybe but there seems to be other cases also. Knowing Tuomo personally is enough to make me forget about it. Most troublesome part for me is that AFAIK PPM has sold 928 rods before 1st wrongly made set we received. I have no idea how many sets or how badly wrong they were but if 1st set we got is any indication I would be worried if I were using over 6 months old set from them. Obviously its engine builders own responsability to to know what works but some people might not realise what they have bought.

I'm not sure why he assumes that a stroker kit with the same stroke as the one he makes has to be a copy of his. What we did was use the dimensions from a 2.5 liter Evo crankshaft and increase stroke 2mm. That's the only thing similar between my kit and his. I use different rods, rod bearing size, rod diameters, rod length, etc.
Well you have stated here that you have use a 2.5L EVO crank with 87mm Stroke and added + 2mm Extra stroke which brings it up to 89mm Stroke.
In the Email send to PPM you have wrote this and i Quote:
The only similarity between my kit and your kit is the main bearing diameter and the stroke. Everything else I have improved upon.

Well sorry i am confused now.. As i said your listings here have nothing to do with this thread.
You have copied their kit ok no problem good luck to you,but stop lying and rubbishing them on the internet

Errka, hope to see your project completed soon.
I dont think there was many problems with the parts accept few sets as what i was told by PPM they have made many different combinations over the years for many people all over the world and and because of the many different designs, sizing,ect.. there was a big confusions in drawings, so when they received a order and arranged production for the 928 OEM rod they used a drawing that was labeled 928 rod but was actually a custom rod for 944 rod. and that's where the mistake was as the 944 rod has same dimensions accept the big end offset.
I know that Jan from Hooka Hey Racing purchased pistons and rods few times and at the beginning same issue with the big end offset, but after realizing the problem the rods where remade and all was ok! Jan is still racing with the engine no problem! and rods and pistons are working without any problem for many years now!
Errka!
I have bougth specialmade rods (160mm) and pistons (104mm, lower comp height)two times from PPM
First time a received the goods after 6 months which in this business is not unusual, however the rod was not correct the pin baering was centered over the main baering and not off center as it is supposed to be, Thomas fixed me a new correct set without any extra cost or arguments, it took six months but he fixed it.
Second time it just took 4 months and everything was correct.
So my experience is that Thomas will deliver but it normally takes time.
However the quality of the products are good and price/performance is very good.
My first set piston/rods have so far cooped with 144 hours of endurance racing, a street driver will never
come close to stress the parts like that.
I think that if you keep chasing him he will deliver good products in the end.

Regarding Tuomo's problem i am not aware of it, so i am unable to comment at this stage but i will definitely ask the question and let you guys know.

During the last global financial crisis when AUD was trading at levels not inflated by the Chinese. I got two sets of piston pins that are wrong length. I don't know anything else wrong with the parts, just lost confidence in PPM after the second set of pins was too short, too.

I just ask them about this, and they have told me that you have purchase the parts in 2010.
They remember this issue and after sending you new set of pins they didn't here back from you so they have assumed all was ok. Tuomo you should have told them about this and i am sure this would of bean sorted for you. If you want new pins contact them and i am sure they will send you correct pins this time so your set is complete!
I was also told that their pin supplier from Europe did have some quality control issues at some stage and some of the parts ordered from them had size and weight issues. PPM was trying to sort this problem as soonest they where aware of this problem. Again this doesn't mean that they have made bad quality products, it means that they also relay on some suppliers to supply correct parts to make everything work together.

I paid PPM on 3/5/2009. That's right there at the bottom of the crisis, S&P500 made an intraday low of 666 the next day on 3/6/2009.
The fact that it took long to get the parts doesn't change that date.
The second set of pins was closer, but after I measured them precisely, still too short. I got a second opinion from an engine builder who agreed. I did mention this to PPM, but at that point I basically gave up and moved on. My time is more valuable now with S&P at 1691...
If someone is interested in low compression 100mm pistons with NPR rings compatible with Nikasil and standard size 928 rods with ARP bolts, I am happy to sell you the whole package for $1350 plus shipping. You'll just have to get new pins for them.

Wow, Porsche parts arbitrage? That's a whole nuther level of sophistication. 
Maybe their machinist was depressed after looking at his portfolio over lunch and he wasn't QC'ing his work on the CNC very well that day in 2009?
I just buy my stuff from Greg, so he has to worry about it being right, not me. Locavore.

Well I am obviously better at timing than selection, if you know what I mean.
I do want to try to figure all this stuff out my own, but it's very good to have people who help me to avoid the most egregious mistakes.

That should go on the wall of my shop - the wall in the furnace room, so certain other people can't see it...

Pistons are special design due to the long stroke and it requires a special design open skirt forging for this kit for Clarence requirements.
Everything is ready accept pistons, pistons are getting coated at the moment and will be ready end of this week. Your order will be shipped out early next week..
Hope this helps..
Honestly moderator I think it is time to close this thread, as every order placed at PPM will be posted up here if there is a small delay in manufacturing really?

Tomas,
Why do you keep posting responses as if you are a third party and not the owner of your company?
Why not just answer customers emails and explain the delays. We all know crankshafts can take 3 or more months to make.
