Hello everyone, I'm new here and this is my first post on the forums or any car forums for that matter. Please be easy because Im still figuring out the forums, and I promise to use the search button
My name is Garret, I live near Lansdale PA and a few months back I bought a 1990 240dl auto for $500 with 240k+ , put a new fuel pump in it and got it running but it is still running rough. Based on what I've read it is just the MAF and I have new one ready to go on the car.....I just really started putting effort into the project a few days ago. Im trying to turbo this car over winter break (this is my first real project car I've only ever worked on other than dirt bikes and my miata. nothing with turbos) The goal is to make a sleeper/ low budget rally car.
Ive been reading up a lot on these forums and many others for months now and understand most aspects of transferring all of the turbo components from a 940 turbo/ 740 turbo onto my 240dl. I went to a pick n pull yard and was able to pick the following parts, I just want to ask a few questions and make sure I'm doing it everything right right so far and that everything will fit my car.
(1) lh 2.2 ecu from a 1988 740 turbo (my 240 has a lh 2.2 non turbo eco) good choice? megasquirt will come later.
(2) 740 and 940 down pipe Which fits the 240 better?
(3) TD04 turbo (no shaft play) with the exhaust manifold and all of the oil lines and the cooling line. how do i test the bov and waste gate and should I check anything else on the turbo? have any helpful links for rebuilds?
(4) I'm leaning toward using 940 parts because they are newer but will they all fit in my car aside from the down pipe which I understand may need to be modified?
(5) As far as tapping a hole in my oil pan goes.. will it matter where I tap the pan? and will cycling a few quarts of used oil through the engine and out the pan be enough to remove most of the harmful metal shavings?
(6) Will the 940 intercooler fit in my 240 without modification?
(7) will my coolant hoses from the turbo 940 hook up with my stock 240dl radiator or should i pick up a 940 radiator too?
(8) Will i need to turn down the boost to stop detonation as soon as the car is plus T and if so what is a good boost controller to start with?
Here are some of my other options and some more insight . I just thought I would share my options, these are less important than my questions i mentioned above :
Not to long ago my friend told me that he has a volvo 940 turbo that he and his dad would sell me for $700, I really don't have much space and I already have a 240 so I declined, but he does not have the car listed anywhere so the offer stands. They were considering scrapping the car because it randomly shuts (no puttering, it immediately dies) off while they are driving and they can't drive it anywhere, but when it runs it runs fine apparently. I think the only problem may be the wiring harness is degraded and that causes the engine to stops, It could even be a loose connector but I Dunno
(a) this was my original and current plan of action. Pull together as many 940/740 turbo parts I can find it the junk yard and hope that I can find all of the parts and put everything together correct (its harder for me to not be able to take everything apart at once)
(b) should I urge my friend to sell me just what I need to turbo my car and offer to pay him $200-350 and let him figure out what he does with the rest of the car? (they were thinking of scrapping it anyway)
(c) buy my friends car, +T my engine with high milage and only swap over all of the turbo parts then swap my non turbo parts onto the 940 and sell it to someone cheap and maybe even profit?
Thanks to anyone who gives feedback and I look forward to being active on the forums through my build. I know I may be getting a head of myself a little bit but I'm very determined to do this and I appreciate any help that is given! :zeal:

As for the turbo, Im going to go ahead and do a rebuild on the waste gate and the CBV. And thanks for clearing that up with the intercooler, Ill look for a pre-92 IC.
