I made the mistake of ordering from Peak Sales from their cumminsstuff.com website. He offers many conversion kits. I talked with John Edwards on the phone and he was super friendly when i ordered. It is true that he is extremely ill, so is his wife. However, the parts he sent me were wrong. I spent weeks trying different things. There was no possible way without drastic machine work to make any parts possible.
The cost would have doubled to fix everything. He replied in an email that he would offer a partial refund but never followed through, so i got totally screwed and will have to start over with a new kit. This started months ago, back in the summer. I had a lot of correspondence with Autoworld, but they never sent the instructions they promised many times. I had to find somewhere else to turn.
I've met Scott and seen his shop. It is more of a factory with more machines than i could imagine what to make with. You get the sense that he can make absolutely any part you need. He was super about letting me check out his truck and answering questions. He took me for a ride in his truck, my dog loved it!
He has plans to weld a heim to his top turbo to keep the intake tube from popping off. The compounds move a lot of air. At about 30% throttle, his trucked moved faster than my modified PSD 7. 3 ever did! Massive potential. Almost everything looks like it was a factory option. A Cummins engine really makes you love the Super Duty even more.
Scott has figured out all of the electrical, even for his 2003 Cummins. He has the Dodge computer tied in to his stock OBDII port and gets no codes. He has his ATS 4R100 shifting pretty much the way he wants, keeping the torque converter locked at low speeds. He has figured out how to make use of the PSD harness and sensors, tying it in super clean like a factory harness to the untrained eye.
After at least 15,000 miles on the conversion he hasn't had any problems. He plans to relocate the oil filter to a remote location since space is cramped with both turbos on the passenger's side of the engine compartment. He fabricated the piping for his turbos and intake. He knows how to make the stock Ford tach work using a stock Ford part number, and showed me the notches that must be cut into the harmonic balancer.
He's great with responses and answering questions, just got off the phone with him. I've read, heard, and experienced many negative things regarding other conversion companies. Scott had the same experiences which led him to fabricate his own parts. Just like Kai said, he really makes things right. Scott used to make some of these parts for other known companies so he's not new to this.
Scott is currently developing flexplates that are about 1/4" thick, sized to use a Ford 6. 0 starter. He said these starters are much more compact and just as powerful. His hope is that it will no longer be necessary to machine the bellhousings on our Ford transmissions, perhaps less cutting off the engine block as well. Unfortunately, mine has already been trimmed for the parts that didn't work. His kits should require less work on the part of the installer. He's also developing a 6. 0 to Cummins conversion kit.
Scott never intended to do conversions or make parts as a business. He's come to realize how popular this swap is and that there is a need for someone to totally figure out every step so that this engine swap is easier for others. He wants to help. I believe Scott is going to become the guy all the Super Duty guys turn to for a Cummins conversion. The quality, service, and knowledge really is that much better than anyone else i've talked to, having dealt with three other known conversion companies.
Keep checking his website for updates. Hopefully my Excursion will be on there in a few months.
