£150 to upgrade the turbo!?
I think some people sometimes might do great mods like that, but for most mortals who maybe have a sprinkling of siezed parts, bad luck and whatever else then the costs to fit a hybrid turbo can be quite high.
That isn't to say it's a good approach. Chances are you can get 175bhp easier with just a hybrid than pushing the smaller turbos hard and needing the injection system working overtime to achieve it.
Thanks for those details Steve. So OEM is in essence a 2.5bar range (absolute), but in the HDi110/2.2 they are aggressive on fault response... I guess just easing off those fault responses is the best bet, just like we can do on the rail pressure ones.
I'd agree the 1800bar sensor is a good fit for pushing hard and it's a cheap and easy fit.
But I think it's always important to let people know that it doesn't guarantee running high rail pressure. You need a good healthy injection system generally too. That might be a dirty rail relief valve causing issues through to a raft of injector leak off issues etc etc...
If you can get to 150bhp/250lbft then stop there and be happy and really think if the £500+ outlay to possibly get to 160bhp/280lbft or so is really worth it!
I guess in these cases like Poodle says it's better to then consider the upgraded turbo route as it's a much faster way to a load more real world performance and probably giving the injection system and clutch an easier time too
