$4000 engine rebuild from 4 Kruzn
Today I saved a fellow Rotorhead from suffering what I went through and getting ripped off by what I believe to be a scam artist/ Con artist/ and in general sad and dishonest individual. My goal here is to educate and inform anyone who is considering getting a rebuild from Conroy @ 4 Kruzn. This is what you might get.
For those of you who don't know or haven't seen these are the pictures and story of my fresh engine rebuild from Conroy @ 4 Kruzn.
I paid $3800 plus a core deposit for this rebuild. I gave Conroy a 13B-REW core on top of the $3800 I paid him for a fresh rebuild, or so I thought. Unfortunate circumstances necessitated the replacement of the coolant seals after less than 300 kms. At this point no blame had been laid for the coolant leaking into the rotor chamber. Upon opening the keg with a fellow rotorhead much more knowledgeable than I, what we found inside was truly disgusting. I received a re-built engine with an FC3S E-shaft. The tension on the timing chain (I meant oil pump chain) was out of spec. We found used side seals with gaps to the corner seal less than 0.10mm and in excess of 0.4mm as per Mazda specs. For those of you in the know, to not use new side seals and to not carefully measure them is completely disgusting. If he failed to spend the proper amount of time sizing and shaping the side seals what else had he cut corners on?
The front stationary gear was showing copper. We had specifically discussed the replacement of any bearing that was in need of replacement. Apparently Conroy didn't think this bearing needed replacement. Onto the porting. The porting looked like it had been done by an amateur, decide for yourself. The rotor housings were in poor condition and Conroy had nicked the sealing surface when he was porting them. He told me that this was "no big deal" and that I was being "too picky". If you can't port the housings without nicking the sealing surface take a few minutes and tape them up, seems simple right? Back to the coolant seals. From time to time in the casting process there can be slight imperfections and indentations in the aluminum along the path where the coolant seal sits. Proper procedure is to fill this hole when building the engine. Conroy either failed to see this imperfection or decided not to fill it. As a result the coolant seal bubbled and I started to get coolant in the rotor chamber. This was the reason I had to pull the motor and the true story of the motor began.
I suspect Conroy did not think I would pull the motor at less than 300km's and could get away with not replacing the bearing. As I'm sure many of you can attest dealing with Conroy is a slow and painful process. Before he has your money he is quick and deliberate. Afterwards however he will straight up ignore you and is a complete PITA to deal with. After calling and text messaging Conroy with no response I decided to PM him on RX7 club. The beauty of RX7 club is that you can see when someone has logged on and of course I knew when I had messaged him. He was completely ignoring my PM's. Fantastic customer service!
Months later in a last ditch effort of frustration before I opened up the engine I text Conroy and finally got a reply. Dealing with him was terrible. All he offered me was warranty work on the motor. Why on earth would I want him to touch my motor again after everything that I found. I asked him for monetary compensation but all he offered was to exchange parts. I accepted the replacement parts. I invite Conroy to come here and defend himself, I'd love to see him try and explain his work.

Just a side note, this is the description of the warranty and motor dis assembly by the professional who performed the inspection.
Quick post and I'm out of here.
Kyle wanted Conroy to take apart and figure out what went wrong. He did not refuse Conroy's warranty, Conroy simply did not offer any sort of plan or timeline for Kyle. After many many frustrating months of dodged and ignored messages, I pulled his engine apart with a couple of witnesses. It was not until the motor was disassembled and shoddy workmanship discovered that the offer of warranty work was declined.
Engine disassembly - this will always be he my word vs Conroys unfortunately. After pulling the timing cover and front stat gear, I advised kyle to go home and get a camera. He took pictures along the way of every side seal measured in each corresponding seal slot as well as any other substandard or out of spec parts. That's all I have to say on that.
This Upsets me to post because I was not expecting to find anything shady upon disassembly. Kyle picked Conroy to build his engine based on his good reputation and standing in the racing community. Unfortunately, the pictures do not lie. Even if Kyle was being dubious and misrepresented the seal gaps, or overheated the motor, or overboosted or didn't break it in... The wrong parts were used, the porting is not acceptable, the die grinder marks on the sealing surface are not acceptable. The housings are out of spec as are the irons and bearings.
No good

Unfortunately up here we don't have many rotary builders/shops which leads to the ones who are in business to be shady and take advantage of people's lack of rotary knowledge. We basically have two shops for roughly 4 million people both of which are crooks in my opinion.

The issue here is the "legacy" mentality.
The "old" he does the "best" work and I never had issues with my car for over 7 years driving it.
These comments and praise are from a OLD!!!!!! Time-line. This would be a great example MIKE TYSON would totally knock that guy out... Yes that is true back in the freeking 80's.
Peoples priority change and there lack of attention and legacy mean nothing, if profit is there game they're going to fall flat on there face to the new-generations. It's sad what happened to you but, someone will find this and will read this, and hopefully will sway there options to a more sought after and reputable builder.
I personally see that BC is doing quite well and are proud of there recent accomplishments and not living in the past. I personally would see what they're offering.
*"adding this in now, Maybe a bit late for me to reply on this topic but I apperciate you sharing this." Community wise this isn't usually done, do to the conflicts that arise do to spite of individuals and relations."*
