Mainly cam issues isn't it?

Also what a lot are missing with BHP figures here (it's a diesel, who cares!?) is the torque figure...look at the torque from a stage 1 PD180...I don't know why but those engines manage tonnes of torque really easily!
I still haven't had anything as torquey since the Golf...
Unless you're deaf, the PD is a sack of crap in comparison... They're rougher than XUDs imho, their delivery is way too harsh and PD is realistically no better than a rotary pump, it's only advantage is more pressure...
VNT does give you a wider powerband, it's not all about torque, it's all to do with how good the delivery is... Spend what you would getting a Fabia on changing out the turbo for a VNT unit on a HDi and it'll absolutely spank a PD in terms of delivery... And not sound like a the contents of Halfords in a washing machine.
Problem is, a HDI with a VNT wouldn't last as long as a 1.9PD with a VNT, wouldn't be as reliable either I wouldn't have thought. And the fabia would put the power down better, not just due to the wheels., and would have more power/torque too.
Although it does seem as if the HDI is the better engine, if kept under the 180bhp mark and is rebuilt. Would love a go at a VNT'd HDI 90 compared to a non VNT one, would be worlds apart.
