Often, when we have an experience with a vendor, good or bad, we do not share the details with others. I have been guilty of this in the past too but I want to share my recent experience at DPI with the forum. The “Cliff Notes” version is excellent results, with a couple glitches, but be patient. I have purchased parts from most of the vendors and part sellers over my 10+ years of ownership. I have had some service work and accident repair at Grady’s (great work done by Rob). My experience has mostly been positive except for a part seller---burn date early 2006. I was interested in DPI’s stainless exhaust and wanted better shocks to replace the “performance” ones I had, two of which failed after approximately 2000 miles. I also wanted some coolant system work and transmission leak repair. I had been to Josh Bengston’s shop for his open house in 2009 when it was McFly Motorsports. I was impressed with his knowledge and passion for the car. I waited to find out what others said about the quality of his work before I committed to spending money.

After hearing his exhaust at the shop and making a list of work to be done, Josh picked up the car on 09/01/2011. The first two months went smoothly until early November when Josh called me to say he found some corrosion in the VOD. I drove over to confirm and saw this: 15124 Not too bad but how long will it stay like that? I opted for the engine rebuild. Most other work had already been completed. By late November, Josh tore the engine down and discovered a bearing starting to spin as well---another reason to necessitate a rebuild. I had opted to have my cylinder heads re-done since I figured why not while they were off the engine. This ultimately led to at least a 5 month delay. The machine shop Josh had given the job to put my heads and others on the back burner. The shop then was sold and the new owners didn’t want or need Josh’s business. Here is where Josh could have been more proactive and not allow them to grind some of his projects to halt. When the heads returned to Josh in March, they did not meet his specifications. He sent them back and, by May, severed his ties with the machine shop. It was May before work building my engine could resume using NOS heads. I know DPI had some staffing issues at this time and Josh was a one man show. He always answered my emails and phone messages requesting updates, if not immediately then within a few days. By June, some fiberglass damage was identified near the rear window. Some cracking had been there but I think the previous accident had worsened it. Josh had a marine fiberglass man repair this but a month past till he was available and the repair completed. During engine reassembly and testing, a rebuilt water pump pulley sheared off and Josh had to get the radiator flushed and pull the heads to confirm no metal shavings spread through the coolant. More time past until a drive was scheduled for August. The night before, Josh called to ask about a jumper that was installed under the start inhibit relay. I had no knowledge of this. I found an invoice two PO’s before me that mentioned starter repair under warrantee but that was in 1998. I think they had experienced the lack of a starter solenoid wiring mod--- http://tinyurl.com/brhnldt --- and bypassed the relay. I performed this mod in 2003 but missed this jumper from below between pins 86 + 87A: 15125 Josh had experienced hard starting then no starting. The new starter he installed plus the jumper caused this: 1512615127 Thankfully, not much wiring was damaged but the car was not ready for a drive the next day. I visited anyways to check progress and here are some pictures: 1512815129 Three weeks later, we scheduled a first drive. The car has never been better---smooth riding with some firmness from Spax shocks, idles better than ever, and looks great. Josh’s attention to detail meets or exceeds my expectations, which are high already. After a few more small things I decided I wanted were done, he transported the car back to me on 09/30/2012. Here are some photos taken shortly after: 1513015131

Observations and opinions:
1. Lower control arm support bars are well worth the money and improve the handling measurably.
2. New suspension bushings are also a great investment. How good can 30+ year old rubber be?
3. Stainless intermediate steering shaft did not change the steering input effort or smoothness as much as I expected. My OEM part must have been in decent shape.
4. DPI exhaust sounds great and looks great. It is not too loud at highway speeds and the ceramic coating is a great option. The exhaust should be the standard to which others are compared.
5. Josh spends a lot of time making things correct that are just included as part of his work. A couple of examples are the engine light switch and suspension springs. I never had an engine light switch but Josh added one for completeness and did not charge me. Since my suspension was apart, he powder coated my springs at no extra charge.
6. Battery cables: Josh makes custom battery cables for the car which are a great update. They are flexible and not 30 years old. Here are pictures of his vs. my OEM ones: 151321513315134
7. On a side note, Josh says the shipping weight of his stainless exhaust is 58 lbs. I weighed all of the OEM exhaust parts he removed from my car and got 60-61 lbs. for the stock one. Not as big of a difference as you would imagine but still a weight savings.
8. One of the very few disappointments is that fact I still have a transmission fluid leak. The pan, and maybe another location, is leaking. The first couple weeks back were leak free but, after a few heat cycles and 3 weeks, here are pictures: 1513515136 Here is at 6 weeks: 15137 The cardboard being moved accounts for the drips not being consistent. I spoke to Josh and we will address this at his shop in the spring.
9. The other issue that needs addressed in the spring is the fact that the rod coming out of the transmission is about 5/8ths of an inch shorter than it should be, per Josh. This causes inconsistent starts in Park with no pattern to when it occurs. In 2005-6 after Grady needed to crack the transmission case to fix some leaks, this problem reared its head but it is now a bit worse. Since Josh didn’t open the case up, it was not thought that this would worsen but it has. It is more annoying than I thought so it will be fixed in the spring.
10. Josh returned all old or OEM parts I asked for that were removed from my car.
11. Josh told me on a few occasions that he dyno’s all new builds but that never materialized for my car.
12. DPI’s stainless replacement parts are all first rate and worth the investment.

Having service work at DPI is really like a cooperation of two enthusiasts with a common goal. I think Josh cares more about some of the cars in his shop than the owners. This is not assembly line work and a lot of time is spent making things right. Josh shows quality of workmanship, attention to detail, and customer service that all vendors should emulate. I will update this thread occasionally as things occur, good or bad.

Jeff,

Thanks for the great review. As detailed as you promised!

As planned we will replace the pan in the spring and run the car on the chassis dyno.

I had almost forgotten about the dark times..... Seven days a week by myself 18 hours a day. Firing everyone and starting fresh was extremely difficult choice but worked out for the best. I pulled from the best this time and have a crew I can truly be proud of.

I think the shifter was adjusted on the cusp of error with the R&R of the transmission disturbing it enough to cause a higher failure rate. I have a few idea's on addressing this issue in car.


I have made a number of concessions as well lately. I finally got to the point where I couldn't have my hands in everything. (which was a long time coming according to many) All engine building is still supervised by me but performed by someone else with much more experience than me. I can't build the 6-8 engines required a month to keep things moving here as much as I want to. It has been very difficult to move full time into management but I have made the move. I look forward to you (and others) stopping out to meet Chuck, Chris, Steve, Tanner, Clayton and Jim. They share the same enthusiasm for the car as myself which makes life great here.


On the customer service note:

I take pride in this business having a personal touch. This is difficult as the company grows larger and it is difficult to keep the wheels on sometimes. I would rather have the buck start and stop with me. This way owners know who will pick up or call back. Nothing burns me more than dealing with calling any business and the person I talk to not knowing what I'm talking about or who I spoke to. I have tried having others answer the phones but I feel disconnected and as though I am missing something. So that is how things will remain for now.

1513015131Holy bloody hell, I have never seen a cleaner, more perfect DeLorean! :jawdrop: Hat's off to you and Josh, that certainly couldn't have been easy to do and maintain.

I recognize your license plate -- I've seen your DeLorean a few times while mine has been there getting a more thorough treatment at DPI. I saw the engine too, but those pictures make it look ten times better! I think I caught him working on it once, I seem to remember him showing me something about LED's in the doors or the dome light, something I am considering for mine. Anyways, everything you mentioned is basically on par with my experience. It's amazing how these engines can be so resilient that problems within them take a rebuild or a breakage to discover. I've had a few surprises myself, but seeing them first-hand, it's really a wonder they worked at all. I never get that with any of my other mechanics -- Josh just isn't one of those ever-present "blind faith" shops.

Excellent write-up! :thumbup:

Do you have a cold shoulder Josh? You haven't lost sight of why DPI is on this earth, it's not the licensing of a name but the execution of what your mission statement states.

With each passing day and every new review, I'm getting more and more excited about shipping 5311 off to Josh.

2 questions based on the pictures above and comparing to the stock setup as in this picture I came across http://www.flickr.com/photos/mr38/4115711521/

1. Is the black harness wire rerouted that comes from the back of the engine to front down right side?

2. I also bought new silicone hoses, do I still need to put the bracket on the left side hose coming out of the water pump?

Billy,

I can tell you that the harness is now better hidden in the VOD but I also had my 81 style harness converted to the later style which I believe makes it easier to hide. I would suggest you still use the bracket with the silicone hoses since the bracket keeps it away from the A/C belt.

As promised, here is an update to this thread about the DPI experience and the few issues that needed addressed this spring. On March 2nd, 2013; Josh transported my car to his facility. The two major things that needed corrected were the automatic transmission fluid leak and the transmission linkage adjustment so the car could start reliably in Park. I also wanted to check out Josh’s new stainless products and get dyno run results that were not done last year. We had set a deadline of late April-mid May for the car’s return.

As time progressed, Josh discovered my lower control arm to frame bushings were deteriorating. He also found that my 7 year old metal door handles were starting to fail due to the crimp pin that controls the axis of motion having excessive play: http://www.youtube.com/watch?v=HK8_YDbwP30&feature=youtu.be Josh checked the coolant pipes he powder-coated last year and found many had powder partially on the inside and it was peeling away inside the pipe. He replaced all of my coolant pipes at no charge to correct this. He told me he has since changed to coaters who are more careful.

On June 16th, I visited DPI and test drove my car. It handled great with no transmission leaks. Josh had test driven the car 104 miles to test the leak and linkage repairs. In addition to some of DPI’s stainless offerings, bushings, and new door handles; I had Josh install his powder-coated lower engine cover support strip and his transmission cooler: 2223922240. The engine cover flex is greatly reduced and the cooler is relatively inexpensive insurance to help preserve the automatic transmission. Soon after this visit, Josh ran the dyno test and the graph appears below: 22241 The first and second runs are with the A/C on and the third one is without A/C. These figures are lower than often reported but refer to this tread for more information about DPI’s dyno measurements: http://dmctalk.org/showthread.php?5491-DPI-Engine-Performance-Stats-DYNO-Results-by-the-numbers&highlight=dyno

It took another month for Josh and I to sync up the car’s return. On July 19th, Josh transported the car back to my home. As of today (09-28-2013), still no leaks: 22242 and the car starts every time in Park. This is the first time in the 11+ years I have owned the car that the transmission is leak free. Josh even called on 09/08 to check how the car was. I appreciate a business that makes customer service a priority. There may be more updates to this thread in the future but my views from the first posting hold true: DPI does professional, high quality work at a fair price but you must be patient.

Of all the years I've known Jeff his car has been clean enough to eat of off. So now I have to ask, is your car sterile room certified? Because if it is cleaner than before it has to be now! :-)

Josh's excellent service has been experienced across the Atlantic, at the birthplace of Democracy and Science.
Yes Greece... :smashfreak:

Could not have my D serviced at DPI as much as I would like to, even if that meant taking away the fun of making it my self.
but a few emails back and forth and the purchase of a dozen special parts offered by Josh made me realize, ITS GREAT to transact with a business that LOVES what it is doing.

Keep up the good work Josh.

God knows, we need serious DeLorean importers!!!!:read:

Thank you for the kind words. I wish I could hop over to Greece and say hi while in Spain next month. I might be able to make it happen!

Totally agreed with ALEXAKOS!
Even if, I just ordered once for now, it was professionally package and the item are really great quality. (stainless products)
For sure, as soon as I will be able to order more stainless items, I'll do it!
Thanks!

True story;)

Don't want to disappoint you Josh, but the weather has tuned to shit this past week. Colder that in is in Chicago! It will be great to meet you and tour you around our ancient city.

But DO plan a trip in the summer sometime with friends or a special lady. Best is end July. We got places here you will never forget.
Will be happy to give you pointers to avoid time and money wasting.
