Keep 306 HDI or buy Fabia VRS

[Ruan]

Just been looking at the problems the pd engines have...

Mainly cam issues isn't it?

I wouldn't say the PD fuel system is worse...  Worse for emissions yeah, which is why they can't use it anymore, but power and economy the 1.9PD wins over 2.0HDi any day!  1.9PD still wins over 1.6HDi in both of those areas...

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.

Absolute bollocks.

You've massively confused torque and power delivery. Too much torque makes a car drive like shit, you want a wide powerband. This is a 2.0HDi 8v RHY 90hp vs a 2.0 16v HDi RHR 136hp:



136 HDi:



Same torque, same power, which is going to drive better...

I don't know where this unreliability thing comes from, yes, if you treat your car like shit, don't service it well, scrimp, it will be unreliable. If you service it well, it'll last you years. It's people putting on second hand parts that causes problems.. Of course, people simply cannot get over "spending xxx on a £300 car"... Just because the Fabia is perceived to be worth more...

PD vs HDi - if you give them the same turbo, they will make around the same power as each other, however the HDi will not sound like shit and be rough as f*ck! I don't know where this thing that HDis can't make power comes from... Remember the HDi has a 46mm turbo, is it any wonder that they won't make any power?

Stick on the GT1749V off a PD130, it'll make the same 180hp that a PD130 will.

All I see is people bodging HDis because they're a "cheap runabout".
