I'm considering a hybrid turbo for my 08 Blackline diesel and wondering if you could give me any advice. It's on 65k miles. What else would you recommend changing? I've been told similar to you - don't go beyond 195 bhp but I'd be looking for 240 to 250 bhp.
I believe the gearbox is only good to 195 bhp - is this true?
What else would you change?
What is the performance like with a hybrid turbo vs. a diesel at ~195bhp? Is it worth the extra?
I'd be grateful for any advice.
well, my 07 Blackline diesel with an Autolusso hybrid is now on around 225 BP, so in order of weakness, the components you need to worry about..
1) clutch, I expect mine to go at some point in the next 5-10k despite that it was new less than a year ago along with the DMF. budget for a stage 2 at some point to cope with the torque.
2)DMF obviously it's easy to glaze it when the clutch begins to fail so consider this as a potential replacement item as well.
3) CV joints will start to become an issue at 240 BHP and as far as I am aware at the moment there is no upgrade, just a new replacement item, although I know an upgrade is being looked into by Alfadoit.
4) injectors, on your's and my 150 variant the injectors will not only be the limiting factor to +240 BHP but another potential weak point as they will be working way above the intended level.
I personally went with the policy of replacing all of the turbo related sensors at the same time as doing the turbo simply because at 100k they were likely past their best, this proved to be right in the case of the maf which failed the week before the change over to the hybrid. I just wanted a clean slate with it all but it's up to you how you proceed with this but at 65k they are probably ok.
I will say it wasn't plain sailing with my turbo at first and the fact that all of the sensors were new genuine helped diagnostically speaking, that issue has been identified and fixed so it will be plain sailing for you.
In terms of more power you may have to fit a 3 bar map sensor but TBH I am not sure at what point in the power figures this becomes relevant.
also make sure you upgrade the brakes with some performance pads and fluid at the very least and if you have the funds some grooved and drilled discs..and if you really have the funds some 330mm discs and bembro 4 pot front calipers.
I would also consider suspension upgrades VERY important, eibach ARB kit would be the very first thing to do followed by one of the tried and tested shock and spring upgrades, think Koni FSD or bilstien shocks paired with eibach springs.
re the gearbox the stock diff is the weak point on these not the gearbox itself so I would say a quaife is 100% required at the level of tune you are considering and will eliminate torque steer and understeer.
can't think of much else but if you have any more questions feel free to ask.
