I want to know what injection pumps were used on the 1910cc 8v turbo engines..

I have a mk2 punto with the 1.9d engine that has a lucas epic injection pump as stock.. I want to turbocharge this engine and use a mechanical pump for reliability..

i've been looking at the marea td100 pump but can't seem to find much info on the net about it..

eper says all the engines are diferent even though i can tell otherwise, same bore and stroke along with the same firing order.. only diference is the higher compression ratio on my engine since it's NA..

so in my thinking if i pull the pump and injectors from another engine and place it on mine it should be good to go.

Any ideias?

I will NOT keep the epic pump, it's widely known lucas pumps are not very reliable but the epic really leaves up to it's name.. the ford transit and pug 406 guys are all going back to bosch pumps since they have similiar engines fitted with them, i have no such luck..

I think you would be much better off looking for a 1.9 JTD in a scrappy. The 8valve engine comes in various flavours between 80 and 140 HP on offer, depending on what you take it out of. You'll also get a tranny that's matched to the power and torque on offer.

Also, there's the small matter of running a turbo on an engine that has a 21:1 compression ratio. Fiat brings that down to a more reasonable +/- 17:1 ratio on turbo engines. Let me put that a different way...You'll be replacing a lot more than just an injection pump in very short order if you do this. Also, does the non-turbo block have a provision to get oil to the turbo that you want to add on?

You'll be miles ahead doing it right the first time and dropping a turbo engine in to start with. The 100 HP JTD that was in the HGT and Idea (and Lancia Musa) would be a good place to start. You may also need the engine computer...

To place it in simple terms i don't want a JTD. The idea is to get rid of electronics and using the JTD is going backwards..

A diesel is not a gasoline engine, it has no limits on compression ratio other then the mechanical limits to hold in that compression. A diesel has no fixed AFR, detonation or preignition do to excess boost, the only limitation is the EGT..

My engine uses the SAME block as the JTD and the TD engines, the only diference is the pistons and oil pan, my gearbox is also the same used on the 80hp JTD with some minor changes..

If you put a turbo on an engine with 21:1 compression, you will exceed those mechanical limits in a matter of seconds. Why do you think that turbo engines have much lower compression ratios than non-turbos?

And same block not withstanding, does it have the oil passages from the inside to the outside for the turbo? If they are there and capped, no real problem. If not...

static compression ratio is meaningless, yes it's easier to tune a turbo engine with a lower static compression ratio and that is one of the reasons turbo engines have lower static compression ratios.. lower static compression has less torque and more lag and as a side effect helps protect transmission components..

the important part is dynamic compression ratio wich will be the same or very close on both engines at the same power level (once a turbo is fitted to the NA variant) the IDI engine will have the advante of greater bottom end torque, less lag and higher rev limit... not to mention it will make more power at the same boost level on the same turbo since it has a higher static compression..

the only thing i'm worrying about is melting the precups on the IDI engine but i doubt i'll get to that point at the power level i want..

yes it does, but it wouldn't be a problem either way...

i'm not new to turbo engines, my initial question was specific
