you can buy form old ttrucks, but are internally wastegated, and on a petrol car will have amazing boost creep, and welding it shut is a uggly job, so that makes you also have to buy a housing. and im not shure but i dont think the inlet housings arent the same as these performance ones :p

I bought a HX40 from this company in April. I have done no more than 300 miles at low boost and I was told on Monday that the seals have failed on the unit and as a result the car is bellowing smoke from the oil that is passing the seal under pressure.

I have contacted the company as it should have a 5 month warranty left, but as it stands I have had no reply.

Its true what is commonly said though, if it looks too good to be true, then it more than likely is.

Not best impressed with this company and their product :(

Did you install it with an oil restrictor?

From service manual hx40:

www.cummins.com/turbos - service repair manuals

Holset permits oil return pipes to decline at an overall angle of not less than 30 degrees below horizontal. All turbocharger applications require a pipe of internal diameter greater than 19 mm which has integrated connectors. To ensure oil returns into the engine under all operating conditions, the return connection into the engine sump must not be submerged and the outlet flange of the turbocharger must be 50 mm above the maximum oil level of the engine sump pan. Crankcase pressure should be limited ideally to 0.8 kPa (0.12 lbf/in2) but 1.4 kPa (0.20 lbf/in2) can be accepted by reference to Holset.

Oil pressure of 150 kPa (20 lbf/in2) must show at the oil inlet within 3 - 4 seconds of engine firing to prevent damage to turbocharger bearing system. A flexible supply pipe is recommended.

The minimum oil pressure when the engine is on load must be 210 kPa (30 lbf/in2). Maximum permissible operating pressure is 500 kPa (72 lbf/in2) although 600 kPa (88 lbf/in2) is permitted during cold start up. Under idling conditions pressure should not fall below 70 kPa (10 lbf/in2).

Recommended oil flows for the turbochargers are 2 litre/min at idle and 3 litre/min above maximumtorque speed.

I worked at Cummins for a year and found that most of the new turbos had China stamped on the core which leads me to believe that some of the newer turbos are Chinese made....

Not everything (well not anymore) A lot of outsourcing is going to India for example Rods were being manufactured in India for Cummins.

Guys,

I worked at Holset in Huddersfield. It is true that Holset do manufacture turbos out of theri facility in Wuxi in China but they are 100% Holset units.......not nasty rip-offs!! Its funny though as i am trying to get hold of a "pukka" Super HX40 for my own car and can I find one anywhere for a reasonable price.......er....no!!!

Andy....did you get your GS Racing unit repaired or did you bin it? I remember seeing you with Bernie at one of the shows lat year after it had blown....not a happy bunny!!

What manifold are or were you using also Andy....just out of interest?

Cheers

Andy B
