[69dieselfreak]

hey guys i have a couple of questions
1 is there a company out there that makes any peformance parts for our cars

2 if i were to get a trans temp gauge where would i put the sender thanks guys for all the help

The first thing to do is to get the pump altered. You are spoilt for choice in the US, where there are lots of injection specialists and shipping charges are not exorbitant. That costs about $700 -800. Compression can be increased by measuring the piston height above the block and if possible taking off one or two of the three parts making up the head gasket. Other minor mods seen here are use of a straight through exhaust which adds about ten hp and replacement of the mechanical pump sad to give a couple hp.
As doing these things will be costly it maght be an idea to do a compression test first to see if the project is worthwhile or if the cash might be better spent on getting a rebuild.

you could try some LPG injection the Land Rover guys get silly amounts of BHP out of a Diesel running LPG injection as an add on.............i think you have to watch the EGT big time though.

now wouldnt you want to lower the compression to get more boost into the cylendars
oh ya i do plan on straight pipin it
and where is the mechanical lift pump is that what you are talking about because i havent been able to find it

First find yourself a handy Bosch fuel pump man who can tune the pump (its in the smoke limiter section of the pump). There are three thicknesses of gasket for your car but beware as they were replaced for the 940 series with a metal gasket which does not need retightening 1,000 miles after head work. Mechanical lift pump is part of the Bosch Fuel Pump. Mine is up to 185bhp with electric fan, stainless steel two-box exhaust, and removal of EGR. A lot of guys stateside have cleaned up the porting, polished and gasflowed the head to great effect. Mine started out at 122bhp which is standard for TIC version, although when fitted in 780 (Italian market only) it produces 127bhp! I have been looking for a 780 diesel turbo intercooler for some years now and not found one yet. My pump was reset by a turbodiesel tuning expert about 60 miles from me. I get a bit more performance when I use B100 fuel.

All the best, Peter.

so the replacement of the mechanical lift pump
do i just put and aux lift pump in the engine compartment and thats it
of course hook up the fuel lines

"Other minor mods seen here are use of a straight through exhaust which adds about ten hp and replacement of the mechanical pump sad to give a couple hp."
A rather sad sentence - as per reply above of course I meant replacement of the mechanical viscous fan with an electrical one, which AFAIK comes from a 760.
If you are going to send the diesel pump to an injection specialist be careful about the injector lines as they are easily chewed up and you will need to reset the timing when replacing it.
You will find a discussion on compression here

Hi Peter

Gosh, you know a lot about cars!! I need to pick your brains about something you've posted on here. My D24TIC runs out of diesel showing a half tank still on the guage. She uses exactly 13 galls before she runs out. I still havent phoned Volvo to determine whether she has a 13 or 20 gallon tank, if it's the 20 it means my lift pump has gone. When the RAC attended a break down due to this when I first got my 940 and thought I had fuel supply problems, they told me that my lift pump was in my petrol tank but on here you say it is in the Bosch fuel pump?? Are the RAC wrong (they frequently are) or are there two different lift pumps? Thanks Peter

Ps - Oh and do you mean a 760 diesel turbo intercooler, not a 780? There was a 760 diesel turbo intercooler on Ebay fairly recently up in Scotland, she fetched a fair price

Hi Laney, to be correct you have a 60 Litre tank. There is no lift pump other than the one that is part of the main fuel pump/distributor. There is no pump in the tank. I think the error arose from the Chilton manual which says "On all vehicles, the fuel tank contains the fuel pump and sending unit assembly" when of course diesel cars using D24 do not have a seperate fuel pump. Possibly there is a partial blockage in the tank. There is only a sender unit in the tank but crud can collect around the outlet filter (internal strainer around the pipe pick-up. Check for water in the fuel by draining the filter using the screw on top (8 or 10mm spanner) and tap on bottom. Let water drain out until only fuel is exiting the filter. There could also be a blockage around the return line to the pump.

Yes I meant 780! Only the Italians could dream up a turbodiesel coupe by Bertone, which is why it came as a 127bhp unit. LHD only, of course, there were no RHD 780s made. Mainly USA/Canada but quite a few European versions. I had a 760 GLE Turbodiesel with Intercooler. The Intercooler and piping were fitted to our favourite Anglo-Swedish member of the club who is married to a lovely Yorkshire lass.

I was hoping to convert a 780 to RHD if I ever find one!

All the best, Peter.

so a lift pump would be a good thing for these cars is what your saying so the injector pump doesnt work so hard
