I was initially asking cause I noticed your twin turbos made the motors foot print a liiiiiittle bit wider. Will there be interference with the way it fits in the motor bay of a bus? _________________ -74 Standard - "CaliBug" 2084T, MS3X w/FI and Crank Fire

Im keeping the rear engine tin apron's tin in the same shape it was in surrounding the pipe work for the turbos. I will have to substitute the OG rubber seal for fiberglass exhaust wrap in places because the tin runs real close to the exhaust. But all in all it should fit in great. The bonus is that the rear body apron of the bus is removable to facilitate the installation of this unusual combination . _________________ Vw collection 60 combi ,61 panel ,62 deluxe micro,82 diesel Westfalia,88 Vanagon synchro,98 Jetta tdi,11 Jetta tdi mt ,11 Jetta tdi dsg.

I'm using Chinese rhb 31 turbos . I have dismantaled them and corrected many flaws concerning the bearings and center sections. The reason that those kinds of turbos fail is because they produce them in a manor that leaves machining partials and casting flaws that cause the oil not to coat or " film" properly . Special care concerning the indexing the compressor wheel and the turbine shaft must be taken with an assembly that small because of balancing concerns . The compressor and turbine housings are all ported as well . I have used Chinese turbos and center sections for years and never had a failure because I use my own special " method " of prepping them . I have serviced the turbos of at least five TDI's in my local aria for customers to support my claim . I would never dream of using one of those turbochargers out of the box because failure would be imminent . _________________ Vw collection 60 combi ,61 panel ,62 deluxe micro,82 diesel Westfalia,88 Vanagon synchro,98 Jetta tdi,11 Jetta tdi mt ,11 Jetta tdi dsg.

Oh yeah the center sections as well as the oil cooler on the full flow oil system will have its own cooling system complete with its own electric water pump and remote radiator with fan . _________________ Vw collection 60 combi ,61 panel ,62 deluxe micro,82 diesel Westfalia,88 Vanagon synchro,98 Jetta tdi,11 Jetta tdi mt ,11 Jetta tdi dsg.

What’s the size of the down pipes?
Looks like a back pressure bomb.
Go up in size big time! |

The down pipes look to be the same size as the turbine side outlet. I don't know it there would be much gain in going bigger. _________________ We had the stone age, the bronze age, the industrial age and now we are in the age of mass deception and mind control for corporate profit.

I went CIS on one of my many engine configurations. I like to go against the grain as well. Kinda pushes you to engineer and works the brain a bit more.

Wrong. Looks like 1 5/8 size, all turbo engines deserves a big down pipe! |

My caliper didn't work that well when I held it up to the computer screen but it seems yours is of better quality. _________________ We had the stone age, the bronze age, the industrial age and now we are in the age of mass deception and mind control for corporate profit. (The mass media age) |

Yes the down pipes are 1 5/8" . Because the turbine size is around 1" , I figure that would be sufficient . And having two of them with a very short length combined with the rather small stock size 40 hp valves should not put to much stress on things . I'm going for a small boost on power with the benefit of a bit better milage. _________________ Vw collection 60 combi ,61 panel ,62 deluxe micro,82 diesel Westfalia,88 Vanagon synchro,98 Jetta tdi,11 Jetta tdi mt ,11 Jetta tdi dsg.

Personally I would have upgraded to a bigger size. At least 2”
Low boost also dictate more exhaust through the wastegate, and it looks like it’s restricted.
Bigger down pipe = less back pressure, less heat, faster spool, better control of boost.. |

That totally depends on how closely the turbos are matched to the engine size. Low boost can happen when the turbo is too big. Personally I would be surprised if that 1200 cc engine has enough huff to open the waste gates... on one turbo never mind two... we will see...
I think this fellow has done his homework and, he is not going to be revving that little old 40 hp engine to the moon and back either if I understand it correctly. _________________ We had the stone age, the bronze age, the industrial age and now we are in the age of mass deception and mind control for corporate profit.

The rhb31 turbo is a dinky little turbo.
Those downpipes should be fine with that setup. _________________

Yes it is true , I'm going a bit light on the turbos . I'm going to compensate with the charge cooling a bit . _________________ Vw collection 60 combi ,61 panel ,62 deluxe micro,82 diesel Westfalia,88 Vanagon synchro,98 Jetta tdi,11 Jetta tdi mt ,11 Jetta tdi dsg.
