![]() Yeah, I suspected I was screwed when I saw that the 740 distributor had a Hall effect sender and the 940 didn't. I have some work to do even after I get the right computer. Curses and various obscenities.

![]() Believe it or don't, I actually saved that sensor from the 940 trans before it went to the junk yard (it got water from a bad radiator in its fluid; all the experts said it was dying). The trans that came with the 740 doesn't have a place for it, so I might be, again, screwed. Or, if I can find the right trans, they're not expensive at salvage, and I'll have the correct motor/trans/sensor combo with the crankshaft sensor, and then there's only the question of whether I need to find another ECU and EZK. Do you know if I'll need to, or, with the right sensor, will the brains in that car run that motor?

the bracket for the sensor mounts on the engine, holes should be drilled and tapped for it already.....cut a notch in the top of the transmission.... ideally you want Turbo ECU's....the car will run with N/A ecu's, but won't know how to handle the extra boost and know how to pull timing did you keep the flexplate with the "windows" from the 940? |

![]() I have an 87 240 that I put a 93 B23FT in and used the LH2.2 and bosch fuel computers from an 89 740 turbo. Wiring was easy. In fact, the old Chrysler computer is still there just unplugged.

![]() hello to everyone here @ turbo bricks, i'm a newbe on volvos, have mine, 88' 240DL, last year, thanks to my granpa, he is the one that always liked the 240's, i'm going to be honest, at first, didn't liked it, but now, i love it, and im trying to bring it back to live. So far, all i've done to it is changed the suspension springs, and i have to say, u feel the difference right away. But, my final plans on it is to turbocharge it, so i would appreciate all the references and advices i can have to reach my goal. thanks to you all and keep up with the nice projects i've seen here!!!!

![]() buy a doner car.... That's the only way to go. My doner was an 88 740t for $250. There are many small things you'll need that I have not seen listed on all the really great posts here. I did mine in two phases. Engine only first, drove on low comp engine with old intake, exhaust and computers. After a month of good results I put the intake, exhaust/turbo, intercooler, computers and other details in. One weekend for each step. Driving it daily now. Actually quite a simple exercise. Good luck.

![]() im gonna ask a question that kind of confuses me, someone said in the early part of this thread that you can use lh2.2 harness and lh2.4 computers. Towards the end someone else said the computer from a 2.2 wouldnt work in his 2.4. so is it possible to use a 2.4 computer in a 2.2 or did i misinterpret someone along the way.

![]() not possible without changing wiring and components as lh2.2 and lh2.4 use different methods of reading rpm signal.

![]() One of our very own is making the K-jet plugs. I'll certainly be buying a set when I change over to LH on our turbo wagon, unless I pull the head. In that case I plug em with allen plugs. Here's the link from the for sale board:

Also, on the 95ish 940, do they use OBD2? And does that cause any issues? Just some questions I came up with that I don't see answered. Maybe it will help somebody out.

The signal isn't low or high impedance in this case, it is the injector. The turbo or N/A ecu's are exactly the same regarding the output driver for the injectors (correct me if i am wrong). They work the same. They can switch the same amount of current. The N/A injectors have a resistance of ~15 Ohm, the turbo ones a resistance of ~2 Ohm iirc. Regardless of the computer you are using, the lower resistance of the low-impedance turbo injectors will cause a higher current draw for the computer (Ohm's law). To limit the current the low-ohm (actually called low-impedance because we are talking about a coil - inside the injector) a resistor is added in series to bring up the total resistance. lower current is the result. The summary: use a resistor pack with low-impedance injectors (like the stock turbo injectors of the 740T/760T/780T/940T/960T). Are you using for example the 850 turbo injectors, those are hi-impedance so no need to add a resistor pack because they have the same 'resistance' as the original injectors that came out of the N/A car. Quote:
No issues. I am using a 0 280 000 984 ecu from a 1998 940 in my 240. That ECU supports OBD2. No changes to the wiring. The OBD1 diagnostic socket still works as usual (all 4 test modes - the codes for LH and EZK and a check for the actuators (injectors, Efan, IAC, FP, evap) and a check for the TPS etc).

![]() An even simpler explanation:
A factory turbo 940 (LH2.4) uses low impedance injectors and a resistor pack. An NA 940/740/240 (also LH2.4) runs no resistor pack, so when you swap over the turbo ECU and injectors you need to add the reistor pack too. Essentially you're just copying the factory turbo setup in your originally NA car. Hen |

![]() Use orange tops (off an 850 I think) and you won't have to add in the resistor pack. That is what I did and it has worked fine. Also had to change the ignition computer to a turbo. Many say the standard 240 ignition computer works fine but, in my case, it pinged like crazy.
Also, a resistor pack is one more thing that can go bad. Had it happen on my 740 Turbo and left me stranded with no fuel delivery.

Another thing I see is 940s needing a certain flywheel/flexplate? If you got the junk out of a 2.4 car, won't it have the proper windowed flywheel/flexplate? I kinda want to do this just so I can make a SOLID how to. This thread is great for some info but still leaves me scratching my head. And fk you guys who say we need to search. If it is so common and so simple, then we shouldn't have to. Something as simple as a parts list should be a breeze. This is a forum. It is a pearl of knowledge. I LOVE how the guys who have NEVER had to search something, say to search. You get conflicting answers and sometimes it isn't specific enough. |

you get conflicting answers because there's more than one way to accomplish what you're trying to do. Search. Read. Broaden your own horizons. Even if you don't use someone else's implementation, it doesn't hurt to know what other people are doing. Further more, no one actually owes anyone anything. If something is common knowledge (and a lot of this stuff is; and has been discussed dozens of times and probably mentioned in every single +T thread ) *you* need to be able to sack up and read and then come up with an intelligent question. If you're having trouble figuring out the what's and why's of a +T, I would gently suggest that maybe its not for you.

Buick Park Avenue Ultra Buick Regal GS / GSX (SLP) Buick Riviera Supercharged Chevrolet Impala SS Chevrolet Monte Carlo SS Oldsmobile Eighty-Eight LSS (limited) Pontiac Bonneville SSEi Pontiac Grand Prix GTP These injectors are 4-hole instead of pintle style and flow 36lbs/hr with a resistance of 14.8Ω. I grabbed a set of 6 off a Park Avenue Ultra at the junkyard and they look like they'll fit right in, but I'll report back upon installing them. If you want an Eaton M90 you can grab one off one of these cars as well.

![]() To avoid starting a new thread for a single question:
Would something along the lines of this: http://cgi.ebay.com/ebaymotors/Volvo...ht_3652wt_1167 be what I should look for? Or would I be significantly better off to find an actual Volvo turbo from a junk car somewhere and hopefully save money? My car is an 88 240 GL Last edited by Wind; 03-28-2010 at 12:29 PM.. |
