ok so.... I'm in the strt of building a chevette powered by a slightly modded isuzu turbo diesel. I ill get the build thread going again when I get some more pictures! anyway heres a few vid's I like: videos.streetfire.net/video/fast-diesel_47350.htmfast 1990 mercs..! and a fast escy mk1 ... ok so diesels can produce big power (with big smoke! lol) so I'm wanting 50mpg and maybe 130hp from mine.. seams doable but any links pics specs and videos would be great... loving the idea of white tyre smoke combined with black diesel smoke..  please add... here is a pic of said chevette:  and engine now with sump modded and manifold 90% completed for a bigger turbo:  si |

I looked into tweaking my old 80 tdi, I had the pump re-timed and it made the car much quicker, all else I was told I could do was a bigger turbo and manifold.
great idea with sticking it ina classic too!!
will it be running electronic or mech injection?

well last chevette i owned i put a pinto in and it went really well butb was only about 110hp best... ive heard of a few people getting around 125hp out of isuzu's with std turbo with boost upped and big intercoolers and fuel adjusted.. so was thinking 130 is possible with a nice manifold portmatch better flowing inlet, bigger turbo and big intercooler and hopefully still quite good on fuel...... id love 50mpg but anything over 40 is good plus it is different?! si |

Ace idea, practical, fast, reliable and economical. Modern-ish TD in a old skool motor is an awesome concept. There are lots of mk1 and 2 golf are getting PD engine in them, which makes total sense.
Performance TD are quite big in Malta, saw a Maltese mk2 Fiesta featured ages ago. It had a Izusu TD with bigger turbo running 19 psi of boost, apparently it was quite handy on the drag strip.

Brilliant idea, I knew of a Corsa 1.5td that ran 18psi boost happily (till it finished up in a hedge bottom). I presume you are planning to use the 1.7 lump if you are thinking about a 16v head. Maybe its possible to use 16v (Y17DT) lump without the electronic pump and all the gubbins that go with it , and a bigger turbo and intercooler.

wind up the boost as much as you like, it's the fuel that causes problems on diesels

with those 1.7TDs, youll only get about 120bhp from the standard turbo / head setup and fueling / inlet /exhaust mods. IIRC they have an emergency pop off valve on the inlet that needs welding shut for decent boost  Theres a guide on Migweb somewhere for the stage 1 upgrade on these. FWIW I believe the 300bhp 1.5TD Corsa someone mentioned actually has an XE on TBs and nitrous and just has the original TD badge on the back. Nitrous works well on diesels, but I believe you cant put the isuzu past 200bhp or you start bending rods. This is all from stuff on Migweb TBH. Considering what the chevette starts with, pretty much anythings gonna rock in there |

using the mech pump on the 16v would be interesting BTW if anything ever comes of it! |

Diesels won't give impressive drag figures AND 50 MPG. They can do one, or the other, but not both at the same time.
For example, my C4 HDi did nearly 700 miles on a single tank, taking in A, B, town and motorway road use. But I was barely ever on boost (as it's a 92 it has the smallest LPT, which comes on almost from nothing at 1200RPM or so and has a very keen leccy wastegate) and used the cruise control frequently, never going more than 80 mph. If I used the performance (it's a handy lump in a C3 but has a job shoving round a 1270 kg C4 with total vigour, although it's hardly what you'd call languid) I'd get around petrol figures. That goes for pretty much any diesel you car to name. Use your 'real world torque' and there you go, great 30 - 50 figures but painfully average fuel consumption.
It's a bugbear of mine that turbodiesels give great MPG and performance at the same time. It's almost as bad as those sodding tabloids that write 'xxxxx is the best thing EVER', until the next 'best' thing comes along. Use YET!!!!! Aaaaaaargh!!! (11!!!!!!!!! OMG LOL!!!!!!!!!!!!)
Still a cracking project though. You could use the LSD and back axle off a Piazza Turbo for if things get really funky rearward.
