Actually he spends a lot of his time doing volunteer work for special needs organizations. As for the rest of this thread and your backing for the supplier here. Simply put you're wrong. The OP has been patient, has been understanding, and has been nothing but a perfect customer. I wish my customers were like him. If they had a car with the finished product on display that means they have the schematics and engineering plans for the kit. Which means it's a matter of assembly and coating. Now albeit proper tig welding takes time. HOWEVER, if you as the supplier have given the customer multiple delivery dates, each time extending it out more and more, no matter if it's a $15 part or a $15,000 custom built engine, is bad business practices. If they truly wanted to have had this ready to go they could have the entire kit assembled in a single day and welded up, then a day to prep, powder coat, pressure test and QC. So no, 4 months is not acceptable under any situation. There are full blown frame off resto's done in less time. If it were me I would cancel my order due to terrible customer service. This is not a "one off" and actually the profit on the kit is likely more than the profit on the labor. You're talking about mandrel bent stainless with tig welding. And even if the turbo is a custom CNC job it's less than a day to do the housing. I would be willing to bet they have a minimum of 50% mark up on the supplies used to put the kit together.
You obviously either know someone who works there personally or you have a serious man crush on the shop. Either way, you sir are the perfect customer for a shop to take advantage of, you forget, he is the customer. This thread has been viewed several thousand times, now that means several hundred people have a bad impression of this company, and when our friends ask us for FI advice we would be less likely to advise using this company. I'd hate to see how long they take if you drop your car off for fab and install.
