Engine swap

Postby jonathanferris10011 » Mon Nov 20, 2017 7:10 pm

Hi Thank you for letting me be part of your forum. I own a mk3 camper van. I bought it last year for 100 pounds. Its a pinto and now the bodywork is done i need to address the engine. I understand that pintos can be upgraded but if i did that it would still not be economical for me to run and would take the pleasure out of driving longer distances in it as a camper van. So my question is.. It has a mt75 gearbox and I would like to mate a diesel engine which has good milage. I run a Skoda Octavia which has the 1.9tdi engine in it. Is it possible to fit an older 1.9tdi on a MT75 gearbox or would you go another way. The banana engine is ok and i know many people love them as they are uncomplicated with little to no wiring but the mileage could be batter.
Does anyone know or an adapter plate that someone makes that i could make this a reality project or someone that has done this already. I did a small search on here but I dont think it has been done but willing and hoping to be told otherwise. Thanks

Otherwise, Do you know of a ford diesel engine that would mate with the MT75 which i suppose think could be an easier route. Overall i am looking for reliability and economy.

I'm pretty sure that the MT75 which bolts to the Pinto petrol engine, is different to the one which mates to the Di diesel engine.
You would probably be best to source a complete engine and box to replace yours :idea:
1994 Mk4 SWB 115 Minibus 70ps Di (R.I.P.)
1997 Mk5 SWB 115 Minibus 70ps Di (Gone, but not forgotten!)
2004 Mk6 SWB T280 Medium Roof 85PS 2.0 TDDi - Vantunered (Also gone)
2008 Mk7 SWB T280 Medium Roof 85PS 2.2 TDCi - Also Vantunered

I have a friend who has just broken a 1998 transit banana engine and box available for £200, was a fab runner too, prob be easy way for you to go as complete and ready to fit

No they are the same, just remove the steel adaptor plate with the pinto and the diesel engine bolts straight up to it.

I wanted the economy from a modern engine and asking around the banana engine doesn't do that too well. Are there any other options?

To be fair, my Mk5 Di was no worse on fuel than my Mk6 TDDi, but then they shared the same diff ratio. My Mk7 is marginally better on fuel (but it is marginal :!: ) but the effort involved in grafting a Modern TDCi engine into a Mk5 would probably defeat all but the most determined mechanics :P

As with most things do do with fuel economy, most depends on how heavy your right foot is. Running this a very close second is the diff ratio versus how fast you want to cruise and the power output / torque of your engine. The faster your diff, (lower number) the more torque you need to maintain a given speed at lower revs, depending on the weight of your loaded vehicle. There are so many variables to consider. You should aim for the highest MPH per 1000 RPM your engine will pull. There is a formula to work it out.
From experience, there are pintos, then there are pintos. The 2 litre van one with a VV is 8.2 to 1 comp ratio. The EFi is 9 to 1 which make a ......difference and will run very well with a VV carb. Mine did anyway, pulled like a train. Check which diff is fitted first 'cos fitting a more powerful engine will defeat any economy drive if you're still revving at the same ....revs.
If you don't have the MT 75 box fitted and wish to do so you'll need the matching prop 'cos it has a flange where the other boxes have a slider, I believe you will need the gearbox support as well, not sure. Then you'll need to match the speedo, cable or electronic and possibly the hole in the floor, plus the exhaust....etc.
Depending on what Hammond does to diesel users later today it may be worthwhile tweeking the pinto, head, cam etc.

I did have this concern regarding the diff. There is little point with a transplant engine revving higher than it would should as this would make any changes ineffective. I believe I have the type h diff fitted to the rear of my van. What do people recommend the ratio should be and is there a vehicle that could be a good donor? Thanks again for all your help

What sort of millage did you get with the EFI compared to the pinto 8 valve?

Does anyone know if the Zetec engine has good MPG for an average driver. I have read it will bolt straight on apparently with a few adaptations

My 1989 lwb high roof camper with 2.5Di regular exceeds 30 mpg, the highest being 35mpg on a run down the motorway from York to Leicester, typical mpg is 31 to 32. My van has bosch pump with a turbo and the 4.63 diff.

Van was originally petrol and I had a complete van as a donor, took the pinto and adaptor plate off and the Di bolted straight in. I would recommend dropping the fuel tank and removing the bobbin filter from the dip pipe and fitting a short length of fuel hose to touch the bottom of the tank like the diesel setup. I put a tee junction in the hard nylon pipe that joins the two upper parts of the tank for the diesel return.

This is a really easy conversion and you should consider if the fitting of a non standard engine is worth the hassle for perhaps a few mpg!

Did you have to run the wiring from the donor van for the diesel setup glow plugs etc or was that reasonably easy. Did you swap over the whole loom?

Hi, There are no glow plugs on a Di.

My petrol van had a carb fire and the loom got a bit melted!

From memory I cut off the petrol loom just after it comes through the bulkhead on the near side and soldered and heat shrinked the diesel charging loom onto it as the alternator is on the other side to the petrol. The four wires that come from near the right headlight ( oil, water temp, charge light & solenoid were burnt so I replaced them with some 4 core wire over onto the engine and then connected them to the various terminals. It was not rocket science!

Cant remember if the petrols have as much sound insulation on the bulkhead as diesels so while the engine is out you might want to address this matter!

Just to clarify, the van pinto and the EFi pinto are both 8 valve. I never checked the mileage, never been really bothered, just top the tank and occasionally note the odometer reading.
Even more so with the current Bosch turbo motor, MT 75 box plus overdrive, 4.1 diff, giving about 29 mph per 1000 rpm.
3000 rpm may be a bit scary....
