bmw 320d are about that ???
you will need vnt turbo ,fmic, upgraded fuel pump maybe from a 320d thats what a few people on tdocuk use, also stage 3 remap, decat, de-egr.
then other mods like bigger breaks free flowing exhaust
best part of 2k is it worth it?
#9: Re: bigger turbo on 20l hdi Author: Lee, Location: EnglandPosted: Mon Dec 19, 2011 1:38 pm ---- A 20litre engine'd car should be more the 180bhp as standard

i will be interested to see how many people there have actually done all those.
in fact apart from the denmark guy i can't think of any; also see a few guys in frances have put a bigger turbo in but the rpm for the peak torque is just too high up.
fitting a VNT turbo on the pug will never be an easy job because most modern turbo run electronic control wastegate; unless you get one custom build

520d run GT17 VNT give 150?
seat leon run 757042-5014S give 170
merc B200 run K03 VTG give 140.
but they are all DOHC 16v, unlike the stupid pug which is sohc 8v; i still think this would have at least 10-20% difference in power
#12: Re: bigger turbo on 20l hdi Author: Edward, Location: In the garagePosted: Mon Dec 19, 2011 4:13 pm ---- 16V shouldn't be necessary on a diesel. 8 valves will flow more than enough at the low revs they run at.
The VW 1.9 engines managed 150bhp as standard.
#13: Re: bigger turbo on 20l hdi Author: Steve206, Location: UKPosted: Mon Dec 19, 2011 6:08 pm ---- Ive just bought a 120d BMW. 180 BHP standard, would push 230 remapped. For me diesels are mainly about torque and not top end, although mine does move quite quickly.

could be right, but there is no harm to have more valves and cam
