sean, if you are ever in the Ohio area, you should come take a ride in my 2v. I have daily driven this setup since 2008 and only switched the hotside to the newer forward facing, its still the same 70mm from day one and 20,000+ miles. I know you doubt it but the car runs like a top and I have yet to change out turbo, wastegate, bov. Im confident in what I sell and run it all on my cars here. There is just no reason if it works for me it will not do the same for others. I understand your concern though with all the talk online
20,000 miles over 4 years, 5000/year, doesn't really seem like a daily driver. But maybe you don't have far to go. I do 15-20k/year. If I had to switch a hotside after a year I'd be pissed.
I'm still in for you to get your first sales out the door and for us to get third party opinions.
My concerns are not from what I read on the internet. They come from being cheap when I was a teenager with performance parts and also from having to deal with international manufacturers day in and day out for my job. Every day I deal with manufactures in China, Taiwan, and Mexico. I know without proper oversight, testing and material specifications, and a significant quality control effort they will try and pull stuff over on you. I issue 2-5 CAPAs per week to international vendors who do not follow our requirements and we get sent parts that are subpar. This is with companies that make millions a year from my company. A vendor making something for someone that has sales of maybe $50-100k per year and probably isn't getting factory inspections or specific requirements from you will get taken advantage of even more.
It's clear you have many potential customers that are willing to jump in. I'm at a point in life where I would rather spend the extra cash for parts I know work and have the piece of mind that it will last and handle anything I want to do. And I won't have to worry about replacing hotsides or other components after a year of use.
