    The Official "Ask Turbo Yoda" Thread

    Want to know stuff about turbos/engines/engine swaps/engine management? Ask Turbo Yoda(he is old and knows stuff).

    Here is a pic of Marty's new bike we are building to lubricate you.




    P.S. Keep it technical and don't expect dumbed down answers.

    Hi turbo yoda ive jist watched your skid factory and i have a question
    You mentioned in 1 of the episodes that the ZF auot trans could take a transfer case
    I own a ford explorer 04 uz V8 awd/4wd and my question is would a.ZF be able to replace the factory auto trans that seems to be piss weak wothout to much modification or is it a bugger of a swap
    Cheers

    I have a 02 NA Subaru Impreza with the ej25 motor. I wanted to know how hard it would be to convert it to the new 2.0L motor. I believe its the FA20 but I'm not 100% sure

    Hi,

    I Am almost ready to assemble my EJ255 that I have upgraded just a bit, and have a question regarding ARP studs thay I will be installing.
    On the manufacturer's instructions it is stated that studs should be hand tightened into the block, but in your experience is that sufficient or should I apply just a bit more torque to them.

    Please advise if possible.

    Best regards

    Alex

    i have a 85 rb holden gemini slx with a 1.5l isuzu 4xc1engine. What turbo would i be looking at and in your experince, do you think it would be easy to get a manifold to fit without being custom made. And also what problems do you think i would run into

    Idiot friend suggested this and now I'm curious. Not sure I actually plan on trying it.
    as a Briggs and Stratton master service tech who has done something similar, I'd say you can use a turbo off any small turbo car. I used one off a passat with low boost pressure to do a turbo charged racing mower.

    Hello again. I feel like this is an answer I can only ask a fabricator like you. Have you used inconel for turbo headers? I am trying to get some as there is no good cast option for the exhaust for my esprit the other option is a wimpy stainless one that can not be wrapped. I have severe engine bay heat concerns as many esprits BURN UP being thet they are made of glass the culprit is usually the exhaust system and a hot day. I am going with the GTX3071R as I looked into it on the account that you mentioned it.
    I think Inconel is a good compromise on toughness in the scientific sense, ductility and weight also the #2 reason for wanting to make my own out of Inconel is the flow. I can do nice clean runs to the flange versus the regurgitation that is oem and the " Upgrae" for 1000 bucks...
    So please any info on inconel if you have used it. I mean real world. I read lots of data my real concerns come with the working and welding bit of it.

    Hey Yoda!

    So I have a EJ25 STI motor that I want to drop into my 2002 Subaru Forester L. What ECU do I need to get and what other things are essential for converting it into an STI drivetrain?

    Thanks for being awesome!
    -Dave
    My Forrester. Current EJ25 engine.

    Hi, I know you are familiar with gasoline engines. But I have a 44PSI boosted 1.9LT Diesel engine car. My goal is to have 300HP and it was done before. But not the way I build it. I'm trying to challenge myself, and I put Water2Air Intercooler Setup to it. Now with a bad tuning this car gave 261HP with 550Nm Torque. with 106Celc Degree IAT. Now you are thinking
    if IAT was 60Celc degree max. It would gain more HP. But Now I have serious IAT problem... Post Turbo temperatures climbs up to 265Celc. Degree.... Water is getting Hot. And I think Front radiator cannot cool it.


    Now I use Turbo from 350CDI Merc, GTB2060VKLR, with original Electrical Actuator. Normally, my friends suggested that I use Air2Air intercooler for this setup. But I wanted to challenge myself. And tried Water 2 Air intercooler. One of my friend is tuning only Mercs in Turkey. He suggested that I use a bosch pump, 0392 022 010 .

    Here is the HE, it is from Dacia 1.6lt engine radiator. 550mm x 480mm x 16mm, Because it was cheap and it fitted without modification.



    And ChargeCooler is about 141mm x 141mm x 200mm



    Pump can deliver 0.5lt/second with max 0.3Bars. What am I missing here... Can you guide me...

    I will also put the total progress of the car to the "members ride"

    Hey Turboyota,
    I own a MT 2005 Subaru Impreza 2.5 RS. Everything is stock except for a Magnaflow catalytic converter. I couldn't afford a WRX at the time and I really want to up my car's power. What is your suggestion for power upgrades?

    I could just pay for a wrx engine swap, then I'd have to change the clutch and probably the chassis. What else can I do to add some more power?
    I have heard that a cold air intake wouldn't do any good for my NA engine.
    I have also heard that a performance exhaust would most likely lead to power loss.

    In the end, I might just sell the car and save for a WRX/STI, but want to see if I can make this RS work!

    Thanks for your expertise!

    This guy in the vid is running a huge turbo. The first thing I would do is check out what the rods can do and what the pistons can do. Factory pistons for N/A are generally not a good mix. I had planned on talking to a machine shop buddy for you but it aint happening I am afraid. Just being me and wanting to go boost. Look into a computer to do EFI and build the internals to spec. If your at 9.5 and start adding boost you better be running higher octant. Just look at this article by Garrett that should start you:
    https://www.turbobygarrett.com/turbo...tio_with_boost
    Sorry I couldnt dig up more.

    Again I do not speak for Turbo Yoda or MCM in any way. Just a boozy mechanic hobbyist that wants to go fast.

    Also Mr. Turboyoda. I have decided that if its a viable option to go with inconel and rent some tig time or get my tig sent to Japan. I am just going to copy the best flowing design I have seen for this car and then wrap it.

You will end up with a hot pistol ready to blow. so lets say for the sake of argument that you have sast aluminum pistones. They would be beaten hard at 20 psi. If you wanted a minor boost at say like 5psi you could just add the turbo and upgrade the carb and do a blowthrough. If you wanted to whamp the piss right out of it and shit unicorn rainbows. you should upgrade to a forged piston and a better head gasket ect. Internals make the external parts work. I am just saying if you wanna blow an old engine like that hard you gotta upgrade the internals. 4 bold main machining good rods bearings and pistones. The more percise she is the more h.p. you can get.
    You should post your desired h.p. what ignition and fueling you want to do. If you want to step in a cam some pissers and a carb... Me thinks you could do a sweet blow through setup.

    Not speaking for yoda or this forum....My advice is bullshit at best. Buttt.... I think your question is a bit vague and needs some goals stated.
    thanks for some help buts its and Australian (Chrysler) valiant charger hemi 6, 265 I have seen turbo versions none were blow through carb style and all had then engines highly modified we want a more street able version than we also can take to the track without being kicked out for going faster than 10s as an example I've link a different charger with a turbo set up. also again thanks for some advice.
