Exactly how I feel.

I received my shipment of 8 housings (of 10 total) a couple days ago. I havent had time to check them all carefully or use any, but the one that I briefly checked appeared to be good. I look forward to getting the other 2 within 3 or 4 weeks.

Well JHB was trying to make good on the loss of my (2) S5 Turbo LARGE Streetported housings which i sent to be cermet coated and then they disappeared.

So after over a year Marc at JHB finally decided (after this topic) to send me (2) 13BREW Housings which were supposively cermet coated and ported to be large enough to support a T78. What he specifically said was "You'll be getting something better then you had"

After the housings getting detoured at Minnesota for some shipping error I finally received them today.

THEY ARE ATROCIOUS.

I'm yet to determine if they are in fact FD housings like they were supposed to be. But there are nicks all over the edges of the housings surface, overspray is all over, you can actually see sanding/filing marks on the surface of the housing, THEY ARE NOT PORTED, and to be quite honest i dont even think theyre USABLE.

So thanks a WHOLE ******* LOT for losing my nice, original housings and replacing them with unusable, unported, CRAPPY ones.

This is RIDICULOUS. I am so furious its not even ******* funny. I have someone building an engine for me WAITING for these housings. So now hes screwing me AND the engine builder. This COMPANY SUCKS, DOESNT DESERVE ANYONES BUSINESS and if i lived in canada id be ******* arrested for what id walk in there and do to them.

I'm out so much ******* money, so much ******* time, and how do they repay? WITH SCRAP PARTS.

**** JHB, DO NOT GIVE THEM YOUR BUSINESS. Unless of course you like dealign with LYING, STEALING, UNPROFESSIONAL JERKOFFS.

am i pissed right now? UNBELIEVABLY SO, Gloves are off.

Sounds like the exchange cores I've been seeing thus far. This last replacement batch appears to consist of all my original defective ones, which I had already gone over and doctored up well enough to use for the most part.

They apparently get a lot of damaged/broken/removed studs, removed exhaust sleeves, corroded/pitted housings, and nicks/scratches on the coolant seal mating surfaces.

FWIW, the mating surfaces can be filled in with jb-stick weld, filed down level, and used without issue. Same for pitting/corrosion that threatens the coolant seal mating area. Pop some used studs in from junk core housings (your builder should probably be salvaging studs and sleeves from bad rotorhousings, as I do) and you're good to go. It's not that big a deal, but when you have 8 housings and have to spend 8 hours doctoring them up for use it does kinda suck. Broken-off studs and stripped stud hole threads are a real pain, though.

As far as the porting, you do have a legitimate bitch there...especially since porting through the cermet coating is a real bitch compared to porting stock housings. Odds are your original ported housings went to someone else in exchange.

Wow, sorry to hear this, I was considering using their service for some of my customers but I guess I'll stick with new OEMs. Thanks for letting us know about the problems.

bringing them to my builder now and gonna see his suggestions, IIRC JHB said to use silicon carbide bits or something for porting through the cermet, with my luck the ****'ll flake off and ill be screwed.

if they arent usable ill post pics, otherwise i dont really have time.

my other housings were beautiful compared to these, i regret ever sending them to be coated ive lost 2 years time and $2000 worth of parts. nevermind the aggravation and stress, plus the fact that those were from the cars original motor so it was almost sentimental.

oh and RotaryResurrection: when i said marks and **** on the surface, i meant the surface that was cermet coated, like where the apex seals slides on, the actual combustion surface of these housings is all marked up to high hell.

i really need to hit something really hard or something, thats how aggrivated i am right now.

Alright Rotor Housings have been officially deemed *UNUSABLE*

will have pictures and further description soon.

And back to the phones with JHB we go.

Well, to no one's surprise, the end of January has come and gone without my other 2 rotorhousings, not even a peep from JHB via phone or email as to the status of them.

I'm currently having some problems too.

I sent in a very nice pair of REW housings and received one nice housing and one that I would not feel confortable using in an engine. The bad one had gouges from some half-*** engine disassembly.

I am currently working out a solution with Marc. He is a really nice guy and is very helpful. I just can't believe the cores they accept and then send out as usable items... they need to do something fast to redeem their reputation and I hope people continue to give them a chance one they do.

I will also say that the work they do to the housings (core quality aside) is outstanding. If they work out the longevity and core quality issues, then they really could be a great option.

Kevin, did Marc elaborate as to why the housings were defective and how future batches would be improved?

Though this thread makes me really sad, I'm glad I found it. I was planning on sending some housings, irons, and rotors that I have spent many hours cleaning and prepping to these guys in the next couple of weeks, but now definitely not. It's sad that this could be a fantastic product, but it's ruined by bad business.

My housings were not flat...in certain spots there was a variance where the edges were "lower" than the center. That is, the center of the apex seal was rubbing while the edges were not. I think I still have pics somewhere. After about 5 miles of driving and 10 hours of run time, the grit finish on the apex seals, everywhere but the center, could still be seen. The engine wouldn't generate over 70psi on all faces, even though it was built tightly enough to make well over 110.

Clearly it was a surfacing/QC problem, he did say they had been having issues with the equipment and recently got it taken care of.

I see. That's good news for subsequent batches, which is what will be going into my engine. Other than the problems I have had with core quality, I have confidence in their product.

IN reviewing yesterday's voice messages, I find that Marc gave me a courtesy call to update me on the status of my 2 remaining housings. Interesting coincidence, what impeccable timing he has!

This is unfortunate... I had considered JHB for coating a lot of my 20B parts. Looks like I won't be doing that now... at least not through JHB.

Here's my take on the pair of JHB rotor housings that I've seen and assembled an engine with:

The actual sealing surface looked pretty good, akin to a new housing. However, there was quite a bit of prep work needed, sanding down numerous high areas and using JB Weld to fill in some gouges on the coolant o-ring mating surface. It looked like the housings had been abused in their previous life. The portwork was also pretty mild, and I had to spend some time enlarging it.

Did you get a chance to take a picture of the unusable REW housing?

It's a shame that the company isn't worth the product.

As an update on my part, I still have not gotten my 2 leftover housings from JHB that were supposed to be sent by the end of Jan. I did however receive 2 messages from Marc @ JHB, asking that I call him back for a status update (why he can't simply leave the update in the voicemail is a mystery to me). Honestly I dont have time to spend an hour on the phone racking up a 30 dollar phone bill just to hear that the equipment has been having issues but they are working 25 hours a day to get these housings done.

I also checked a couple of the 8 housings I already got. They appear to be much more flat than the previous batch but still not perfect...where chrome flaking normally occurs on the rear edge, there is a 1-2 thousandth dropoff extending 2-3mm inward there. I know they'll run that way, but the whole point of this is to have a perfectly flat surface instead of a chrome flaked one that isn't. Yet the surface still isn't flat.

I'm not sure who you're asking. I have a picture of the REW housing that I didn't want, which they had me send to another customer.

Kevin: I'm still waiting on my replacement too. It's spring and I want to get this puppy on the road!

From what Marc told me, it is my understanding that when there is a large amount of material missing from the edge, it can't always be filled in, even with an additional coat of cermet material. He said that from his experience this would not result in any noticable drop in performance, since it's on the power stroke area and not the compression area.

He also explained that the reason they chose to give me the housings that they did, was because they had a better trochoid (compression) surface. They consider the trochoid sealing surface a higher priority than the coolant channel surface areas. Honestly, I would rather an engine held coolant longer with slightly less compression, than vice-versa.

I finally got my new housing. It looks great.
