S-10 to diesel build

[96jetta]

a buddy of mine wants to put a 1.9 into his little s-10. The project will mostly be done in his garage and for the most part we can figure out how to change it all around. there are a couple questions i still dont know the answers to and i was hoping for some help. mainly what kind of tranny should be used here? he does want to keep it a RWD truck. The other question i have is should all the fueling (tank/ lines/ pump) be completely changed out or just cleaned out?

there will probably be many more to follow. thanks again for all the help

As for the tank lines blah blah issue. Does the truck utilize a supply and Return line from the tank? (one out and one back in?) these diesels do require a return line to the tank and that the tank be vented. As for cleaning it out, that doesn't have to be done just when you do the swap make sure you drive it around first and take it down to around 1/8th tank or so. Then fill it with diesel and Auto Trans Fluid or the first tank. (I say 1/8th because we don't want you getting stranded trying to get rid of the fuel:), and aATF for EXTRA lubrication) Diesels can run on up to 25% gasoline or 1/4 tank. so 1/8th and you'll be safe.

As much as I can help for now. lol

Goodluck!

make an adaptor plate to use the stock chev transmission. assuming it is a 5 speed. or you most likely are taking out a gay 2.8 v6 and a 200r4 auto trans. or you could get an adaptor to go to a toyota transmission. they are pretty much bullet proof. and plentiful. or you could make one. dillenger1 made his own toyota adaptor. the flywheel is pretty easy to machine to fit on the vw crank, then drill a new bolt pattern for the VW in the toyota wheel and bolt it on. dont forget to machine a crank bushing for the input shaft of the trans. then build a driveline accordingly.

what is the auto trans fluid going to do here? it is a 5spd out of one of the 2.2 4cyl. is there a place who sell them or i just have to find a shop willing to machine the required components for me?



                         thanks again guys

running trans fluid (which is rich in detergents and lubricants) is just like a fuel additive. It will help condition seals, and break up any gunk in the tank, lines, pump, and injectors.

alright. thanks again

so will high concentrations of Bio or Power Service

We know.

Let us know how you make out. the tough part will be hooking the trans to the engine. If you find a good machine shop to do it, share the info.......

ATF is not a fuel or an additive. It should never be put in the fuel tank as it will coke the injectors.

ill post pics when we start the build for you all. as well as any shops or people lending help. should i use diesel fuel additive then?

i run it in every vehicle i own, gas and diesel. I have felt noticeable power gains after running it in my 1.7 and of course my atv owes its life to it. I think the contrary of your statement. Fuel to a diesel is anything it can sustain itself on.. Pretty sure I have run my engine on a bottle of pure ATF before. so to me it IS a fuel

Also I said it is "like" an additive in the fact that it is rich in detergents. It is practically the same chemically as an expensive bottle of (insert your favourite diesel engine purge here). It lubricates and breaks down gunk in the pump, lines and injectors can't see a downside to it.

whatever you do, make sure you use an additive.  i like power service myself, as it increases the cetane rating for a little power boost.  then again, you could always mix acetone with your diesel for a power boost as well.  there are many write ups and info available online to give you an idea of how much you need to add.  you need to be VERY specific with quantities or you can negate the power boost.

so you need to keep the acetone at a 2 oz. per 10 gal or so level.  i would encourage anyone trying this to pre-mix the acetone & diesel outside of the tank, so to keep it diluted, as full strength acetone likes to dissolve MANY things!!!  maybe even the filler neck???

add some stanadyne fuel lubricity additive, or the like, and boom!

Fuel to a diesel is anything it can sustain itself on.

Incorrect. Fuel to a diesel is whatever the engine's designers made it to run on.

Incorrect. Fuel to a diesel is whatever the engine's designers made it to run on.

Also Incorrect. So what your telling me is that Dr. Rudolph Diesel designed a diesel engine to be run on WVO, WMO and Bio? Very common fuels for many Diesel engines last time I checked around.

Pulled this from Wikipedia for shiggles.

Diesel engines can operate on a variety of different fuels, depending on configuration, though the eponymous diesel fuel derived from crude oil is most common. The engines can work with the full spectrum of crude oil distillates, from natural gas, alcohols, gasoline, wood gas to the fuel oils from diesel oil to residual fuels.
