The Ceed is definitely a turbo diesel - there's no way any non turbo diesel will deliver 113bhp without unless it was 3 to 3.5 litres in capacity. And there's no way you'd fit an engine that size uner the bonnet.

All modern diesel cars are turbocharged - the only exception being some of the VW Groups SDI badged ones. But they are spineless - 68bhp from 1.9 litres - what's the point.

The Ce'ed diesels are 1.6 litre units. Both have turbos. The lower powered one is 89bhp; the one you're driving is 113bhp. Whether you'd get the 89bhp up to 113 is doubtful as it probably won't have an intercooler.

The high pressure injection is also key to performance and economy. Fuel raill pressures are typically between 1300 and 1800 bar. Yes, that high. Not PSI, BAR!!!

It's is probably mappable, although some of the Middle Eastern cars use unique CPU's, which could cause some delay in finding a specialist.

I urge you to avoid plug-in tuning boxes; they're crap and will leave you with emissions problems and poor economy.

I'm a big fan of Celtic Tuning and I know the work on Hyundai diesels with great success.

I reckon that the 1.6 Ce'ed would go from 113bhp to about 150 without compromising economy or reliability. The increase in mid range shove will be massive. You'll get fourth gear acceleration times that make three litre petrol saloons look a bit dowdy. All this torque means massively easy overtaking.

Go for it!
