Has anyone here uprated there turbo to a hybrid? I ask as i am quite interested myself in doing this and wanted to know what people thought. Also if you have had it done, who did it and what was the cost and how many horse do you now have?

A turbo by itself will not give you any more power - but will change the drive characterisitics.
A turbo change (away from standard) should be matched with a new calibration (remap). Personally I would stay away from a generic fixed geometry turbo. All of the Td5 hybrids I have seen are nothing more than an bigger compressor wheel - which is hoped will give more flow for the same boost... but in reality all they are a mismatched compressor wheel and housing and have a small window of usable gain. They end up being lazy at low speed (low gas flow) and pick too high up the RPM range to make full use of any advantage gained. They do often give the placebo effect - but if you look at power/torque before and after the gain isn't huge if you look at the shape of the curves. Not just because I instigated its design and manufacture - but you are much better off with a proper variable geometry turbo conversion - as made for me by Turbo Technics. A variable geometry turbo conversion results in the turbo always spinning at close to optimum in terms of controlling gas flow - so you get massively reduced lag, better mid and top end pick - and much nicer overall driveabilty.

Ok thanks for your advise. I forgot to say that i have had a JE engineering stage 2 re-map, I also fitted a Serco? large face intercooler and Samco hoses, removed the EGR and blanked it off and have removed the centre silencer with a replacement straight through section.
I have seen one of your videos on youtube of a td5 with variable turbo and it sounds amazing, how would i go about fitting that and would i then would I have to have it remapped again? Also at what price? |

It seems after chatting to alot of the guys at work, it seems that I won't be getting a turbo upgrade after all, with all the things that i will probably have to replace either way!! Like new drive shafts, perhaps a heavy duty propshaft, and a heavy duty clutch that can take the torque! also a few other things to name a few. However i will probably get the fused front KAM shafts as a precaution on the stage 2 re-map just to save future complications. Plus there is a strong chance that i will get the Discovery 1 transfer box gears in mine to lengthen the overall drive and stop the screaming engine!!

I think it all depends how you drive it. As I understand it, there's nothing wrong with having more torque available (especially if it's more evenly spread than the stock setup) as long as you don't continuously push it to its limits. As for clutches... Tell someone you love them today because life is short.
But shout it at them in German because life is also terrifying and confusing... |

remember that everything after the gear box / transfer box sees a load more torque the lower gears you are in so should cope happily in the higher ranges if not abused. regards the clutch I have found in all the vehicles I have modified in the past that generally the clutch is quite happy to take all the extra power once it is fully released but slipping it or dumping it at high load will kill them very quickly.

My drivetrain in the 110 is all standard, and it's a heavy bus, and nothing has broken.
As said, in low range the torque is much much higher anyway. My clutch is on its way out, but that's just wear (and down to a previous leaking FPR  )
Think your work colleagues are unduly worrying. |

I'm lead to believe that my td5 has had a new turbo and a stage 1 remap.
It certainly feels livelier than others I've driven, but there could be so many variables and without dyno testing I'd never actually know about the power delivery. If you took all the seats out and took the roof off that'd give you a better power to weight ratio for example. I think you have to go the whole hog and have turbo, new pipes, intercooler, air box/filter, exhaust and manifold and active re-map. Otherwise the turbo is just one small piece of a larger system and changing it won't make much difference. An old friend did some work on his 1992 Escort Cosworth and he had to change the whole system to get any real improvements to the performance of his car. Same with a Subaru Impreza owner I know. |

Well, I'm pleased to say I can let you know soon. I'm limited by what I can do, as removing the cat is more than my life's worth in Germany and the airbox on an LHD aircon model is pretty much untouchable - all I have done is remove the propeller and trim the useless bits of plastic, as well as fitting an ITG filter.
I DO know that the BAS remap alone has made a huge difference, and fitting a bigger intercooler made an even bigger one. So I suspect the new turbo might not disappoint... Obviously completely rebuilding the engine and peripherals to extract every ounce of power is one way to go about things, but smaller changes obviously can make a difference too  Tell someone you love them today because life is short.
