What Fuel Mileage Does The TDI Diesel Swapped Toyota Get???

Stevenson is the MAN on the TDI!!! Love this build.

[@trevorloucks2505]

You can try to advance your pump timing a few degrees and that should help with the high egts. It'll help get the fuel to burn a little more complete in the cylinder vs allowing some of it to burn or escape to early into the exhaust. It helped with my 03 tdi a lot and doesn't smoke quite as bad as it did either

I saw another builder somewhere on here the other night but I dont know who and it didnt save history. He put "heat shields" around the intake and turbo to help lower egts. I thought you might craft some of this into yours at some point after seeing how well you craft your builds. I'm still plugging away on my ALH now installed but lots of wiring and coolant structuring to do still yet. Cheers from the south.

I can look up the specs of course but what is the main advantage of the TDI engine over the yota 3.0 or 3.4L. I get that the MPG is a little better, but are you also gaining HP and torque?

[@georgehennen4659]

The answer is yes to both those questions. The 3.0 has head gasket issues. The 3.4 is just underpowered

[@oldowl4290]

@@georgehennen4659 I have the 3.0 and the head gasket was replaced under the recall at ~100k miles. I’m now at 175k with no issues. So to my knowledge it’s not a huge thing, apart from the original OEM gaskets. I’m much more concerned about the well known head cracks of the 3.4 which cannot be repaired. So I’m looking at the TDI or even the new Cummins 2.7 crate diesel (which seems best since it’s a new pre-built). I’d probably prefer the yota 3.4 due to the ease of the swap but again, just seems like trading one headache for a bigger one..

I know it's been a year but wouldn't a 4.88 gear give you worse fuel mileage? If you put a 3.73 in it you would increase your mileage and lower your at speed rpm

[@chrispalmer1255]

Maybe it has to do with the rpms the engine runs at?

[@chrishansen7004]

It probably runs best with 4.88’s. smaller motors don’t make much torque so you have too compensate with a lower gear otherwise it’s gonna put alot more load and use more boost and use alot more fuel.

@@austinniemela so the 900 range isn’t so bad....what rpms in the Jetta vs truck? Also compare injectors, tune etc Jetta vs Toyo.

I’m not sure what turbo you have, but if you have a good intercooler, free flow exhaust/intake, and you lowered the gas intake with your remap, you might need a bigger turbo. There isn’t much else to do. A bigger turbo can lower egts a lot.

[@mrm4155]

[@gvaly699]

Hello , Austin. Just an opinion - by the sound of the engine I would assume your turbo does not work - I understand you swapped with a bigger one , but I don't know what type and how it is controlled. This is also a possible reason for high exhaust temperature - if it is a new unit it should work , so I would assume there is something wrong with the way it is "controlled" - I would assume your EGT is decreasing after you drive a while because the software is remapping the engine due to high EGT . Also , an intercooler (or intake) leakage will have the same effect . There is nothing wrong with the timing , or mapping ,I suspect , maybe injectors are not quite "equal" but they seems to work well enough , but definitely there not enough air . Hope you do not mind .

[@austinniemela]

28 psi and the turbo doesn’t work!!

[@austinniemela]

Also injector balance is great, all couplers and piping is new, no leaks.

[@gvaly699]

OK , seems to be a good pressure (1,9 bar -28 Psi ) , but I would go further and ask you if you are sure it is "relative pressure", not "absolute" one ! What that means is the device measuring your pressure has already extracted the value of atmospheric pressure from measurement and displays for you the" relative" value - if this is relative value(28Psi=1,9Bar) then your DIESEL engine should sound more like a (turbo)jet !(!) If it displays an "absolute" value then the real pressure is somewhere around 13Psi, way not enough , and it actually "sounds"that way , but I could be wrong. You could determine that if your pressure start increasing from "zero" or it starts from 15 Psi up. If you are correct and the turbo works , then I would suspect something wrong with what is called "valve clearance" - it should be specific for that engine (I do not know what type is it) , I saw it has hydraulic lifters - or with the system that regulate the "valve clearance" via oil pressure . Also if this is true , the inlet pressure should be higher than what you have . Thank you for your patience .

[@austinniemela]

@@gvaly699 yes lifters are hydraulic so no adjustment. My boost gauge measures actual pressure. So 0-28 psi.

[@gvaly699]

So the pressure should be OK for now. Turbo has variable geometry control , waste-gate control or no control( a picture would help, or I would try to find some images in your recordings) ? If there is variable geometry , a faulty control valve will not adapt the turbine at low rev especially and the engine will be noisy , with low power and black smoke( like yours) - it will still make boost at high revs . Regarding lifters , "hydraulic" does not means "no adjustment" by default - in your situation , with a fix camshaft touching lifters there is one possibility to use hydraulic lifters only for valve shock damping , in which case you will have "fixed" clearances for intake and exhaust , values ​​that should be set according to engine specifications(lifters pre-load) - the values should be engine specific or lifter specific possible , if you are using modified lifters. . Also , these "fixed" values will actually vary depending on oil pressure and you will have certain values with cold oil and another with hot oil - this could explain EGT decrease after driving a while - using thicker or thinner oils will have different effects also. A second possibility would be to actuate lifters in a controlled manner via oil passages through cylinder head - all depending on engine type and/or management system . I do not know what engine type you used.
