hello, i was wondering if anyone has had any expierence with these turbos, i.e. are the just ebay, cx racing, obx, garbage. or are these well made products. i was gonna do a bnr stage 1 but after shipping both ways and tax its almost 600 dollars. now from what i understand a bnr stage 1 is essentially just a hitachi-16 turbo with t04b turbine. well rotary works has a entire t04b turbo for around 300 dollars. which is why im questioning quality. i see no name brands on the turbos so i hve become more skeptical. if i understad right by going full to4b turbo i will need a new turbo manifold and a external wastegate.

i am not interested in the rotary works T3 T4 t04b because of its capability of supporting more horse power. i would be happy if it just supported 300 horse power(website claims it supports over 500hp), because those are my goals with the bnr stage 1. im tempted by the rotary works turbo because of cost, and i wouldnt have to wait a month to several months for my turbo like i would have to for the bnr turbo. now i know that cutting corners is the worst idea when it come to building cars which is why im looking for info, thanks in advance

 

No idea. Try shooting them an email or calling.?

The similarities are amazing! Looks like the same thing to me. Also consider that a turbo like that will require a new exhaust manifold, custom water/oil lines and a standalone EMS. A BNR Stg. 1 is a hybrid stock turbo with a T04b V-trim compressor wheel, ported wastegate, etc...

 

Agreed they look like the same thing, I went through some of the other products & their exh manifolds look like the same old E-bay ones we have all seen.

 

The BNR is a bolt on upgrade and has a good reputation.

 

for a bnr stage 1-2-3 it is possible to do without you sending the stock unit to them if you port the wastegate yourself.
they build the rotating assembly and compressor housing, you can bolt that straight onto your turbinehousing

brian offered this option for me, as i live in europe an shipping would be a bitch..
(not that i took this option as i went for stage 4)

 

i noticed the price of their turbos while browsing their site and they just looked too cheap of quality to me, and a HP quote of 500 is WAYYYY too high for ANY T04B turbo even with a 1.15 hotside to be able to come close to pushing.

looks like a cut and paste of what the chinese turbos claim and cost. so if it looks like and quacks like a duck, well you know the rest..

i bet that it blows up at 18psi which is half of what they claim it can push.. 35psi? lol, right.. i guess it doesn't produce any boost below 5psi also, since it only has a range of 5-35psi...

 

im not gonna shoot them an email because i know they wouldnt be like yeah the turbos we sell are ****! dont buy them. and yeah i figured as much with the turbo manifold and wastegate. just out of curiosity rotary rocket. the t04b turbo would require a standalone, so an rtek 2.1 wouldnt work? just curiouse because thats what im going to be using. i will just stick with the bnr unless someone chimes in with some info that backs them. and i dont see that really happening

 

i can not believe a new company like rotary-works is going to start a new business buy selling garbage turbos

 

did you guys actually try them or just assuming from what you heard about cheap turbos? Go try one, I hear some cheap turbos are actually good *and some are not, depends on brand*

 

you try one..and you will get what you pay for..have u ever seen a cheap turbo explode.

 

It can work. There are a handful of people using Rtek 2.1s with full turbo upgrades, but hybrids are definitely more common. You'll have fuel and timing control like a standalone, but you'll be more limited with injector sizing and boost levels. The MAP sensor can't read over 1 BAR/14.7 psi, and the largest injector you can control is 1000cc. Injectors also need to be reasonably similar sized to avoid staging stumbles.

 

rotary works and cxracing are owned by the same person.

 

i been trying to figure out were there getting there gilmer pulley kits. i know who ever there going threw has to be cheaper than them..

 

haha i know right, ironically id never touch xxr/sportmaxx/rota wheels yet im saying to try these turbos. I have a friend who beats on a godspeed turbo and he says it rocks.

 

hmm didnt know the map sensor could only read to one bar interesting. well thanks you for clearing that up

 

Not exactly true;

It was even higher later with an intercooler around 450rwhp.. so 500bhp is doable..

 

Corky Bell (yes, that Corky Bell) sells a lower priced system he calls 'Shanghai Turbos' on his website. He doesn't add an additional warranty beyond the Manufacturers warranty. He says they have been testing those turbos in-house for 10 months with no issues whatsoever.

50 years ago, 'Made in Japan' was the punchline of a joke.

China is coming on.

 

sorry but i dont know who corky bell is, care to explain? so shanghai turbos are the same as obx, cx racing? or are you just saying that chinese turbos are making a come up?

 

If OBshit turbos is anything like the OBShit header I bought for my last car... :shakes head: stainless steel must have been the lowest possible grade ever, and it didn't even fit. Where it connects to the midpipe was 3 inches too short and to top it off, the flange was slightly rotated. That's quality man. :/

 

No. Don't know. Yes.

I have seen several ebay turbos fail in under 30 miles.

 

i could imagine maybe a quality namebrand turbo like garrett to hit 450 these days but not a no name brand turbo with tin fan blades.

 

I 100% agree.

 

masterpower turbo's out of Brazil have been holding up well from what i have seen. more money that the chinese and kind like older garrets.
