Hexon Marshall CHSC NOZ my life of suffering

[MJ335]

hey guys

just wanna put my story here on the table, to prevent others to make the same errors. Im not going to write this post to the respective sales threads as im not looking to get a $#@!storm on me. This is just my story of suffer to get some bhp more out of my car.

Im do not also like to get involved my dealer/ installations shop on this, as those guys are very nice and make all the installations form the first unit for free. So for sure im not going to put them in the same boat as Hexon, Marshall, CHSC and NOZ.

The story did start back in early 2016, where i bought with my money put aside a Hexon600 turbo upgrade incl. installation service and some hardware parts. After long time of waiting 4 months i got finally my set. So happy as i got the installation imidetally done! But this feeling did not last for long, as after break-in (300km), by using just a stock turbo stg2+ mapping, the rear turbo flow apart. I think this experiance is well known. And next also Hexon closed down, perfect!

lucky me the installers had still contact to an employee (Wayne) from Hexon, which continue the business with the Brand Marshall (co-op CHSC) and came up with a free replacement. Even the turbo was smaller as the Hexon600 i was happy to get a replacement full free of charge incl. installation. Better smaller and reliable my toughts on this. After break-in of 300km, making some pulls with stg2+ stock turbo mapping and all went good. Then made a 20psi straight to redline mapping and all stillgood, so happy!!!! But unfortunatelly this feeling last just for 4000km and blue smoke starts to came out from the exhaust It was Nov 2016 and again i had to visit the shop. What now? I got informed those units wont be sold any longer, what the heck! what now??

From the shop i got the offer to go for a BB stg2 Turbo replacement. It looks promising as i got to see professional CHAR pictures branded NOZ Turbo Engineering. The shop received one of the very first units of these turbos, together with an Australian dealer. The turbo run already for 2000km and absolutely no problems. I saw the logs and the spool ability were just great, stg2 turbos and spool like stocker, perfect! As the supplier was still the same (Hexon, Marshall, etc) i got again a free replacement. So lets go and all good things come in threes. After long time of wait and postponing the ETA, again and again, my stomach feeling start to get worst, it somehow remind me to the Hexon story. But then finally i got my unit... Wow, they looked so nice like absolutely new units! It was March and i go for the next installation.

This time the installation should be done from a partner of the initial shop, as this shop its just sitting near from me. After a while just got a bad notice from the shop, by installing the turbos, they notice that the comp. housing spins on the char. $#@!! Luckily me the shop had more of those NOZ bb units and we took the way of 250km a picked the replacement up. So happy that installation can be finalized and i got my car back. So again brake-in, then put the the 20psi straight mapping on it and lets go. i was impressed, the spool behaviour and also the nice bb sound of the turbos. You can imagine what happens now after 1500 km No smoke, but the turbos starts to howl pretty loudly... so it would just be a question of time, that also this turbos will fly apart.

After taking down the downpipe, it was visible that the turbine wheel was touching the housing. So again take the rear turbo down and take the way to pick a replacement shop to get the next installation done. Uff, suffer again! I was almost to going to sell the car after all this. So again i went for break-in. I run the car for approx 1500km and i got a more or less good feeling. Perfect i run the turbos for some couple of thousand km more without howling issues or any smoke. I just realize if i pull the car for long on the German autobahn, the car suddenly has no power. I did initially not allocate the issue to the turbso. Went back to the shop for further investigation, to see what the problem could be and i got informed "the BB gets to hot and will block". They had the same issue also on the N55 Turbo. My thoughts "What the $#@!, i run not even 20psi redline and the turbo blocks if i pull the car to long!!!". You can imagine now what happens, it took a couple of thousand km more and also the third BB set flow start to smoke and after 5000km they fly apart.

After all this i almost fight the local shop owner, even i never fight somebody in my life. I was so f**** frustrated after having a car for more as one year not running properly. After all this, he show me all email, whatsapp and facebook conversations and i saw plenty of messages going to this Wayne and that the local shop is in even the bigger s*** as me. Finally that Wayne also stop to replay and made a typical made in Taiwan phase out.

I finally got a TTE550 from the local shop, even i had to pay for it, im finally happy to run a reliable car again. And this turbos are pushing so much more as those $#@!ty bb turbos, where no company stand behind.

My advice to you guys going for upgrade turbos:
Use turbos from registered, well known and long existing companies.
TTE, Vargas, Pure, etc.
Think about what will happen, if after 6 months of sales, turbos starts to make problems and this companies have to make huge replacements (like Hexon). Taiwan and China is well known just to close down and reopen the same company with other name at the same address. Look deeper what the selling company is.
nozturbo.com for example, there is no contact address, no FAQ, no anything, its a risk.

Hope i could help you by adding my story, to preventing you from the same suffer as i did.
