Hey everyone, I looked through the forums and couldn't quite find my question so here's another LH2.2/LH2.4 thread.
I have a 93 240 n/a with an AW71 which I'd like to replace with a B230FT from an 88 740. I had originally planned on keeping it LH2.2 from the 740, but the more I've looked into it, the more it seems that the head mounted distributor from the 740's B230FT wont fit properly in the 240's bay. If I swap the FT into the 240, will I have to remove the head mounted dizzy, plug it's hole, and add a block mounted dizzy? If so, since the 240 is already LH2.4 would it make more sense to get a new (to me) turbo LH2.4 ignition? If I were to go this route would my MAF and other sensors still work properly/migrate over to the older turbo motor?
Thanks in advance!
Take the b230FT
Swap in a distributor from an 83-93 240 and use the accompanying intermediate shaft. This gives you a chance to replace all of the front seals and timing belt for that leak free goodness.
Find the ECU's from a 90-95 7/9 Turbo. The newer the better. Some have EGR. Some dont. This can be dealt with in a bunch of different ways.
Use the harness, sensors and MAF from the 240.
Use the flexplate and the crank position sensor from the 240 on the 740 block.
Have a downpipe made that clears the stock oil cooler and fits in the 240 (fairly easy, or you can unthread the stud from the oil cooler and thread it into the block on the 740.
Use this chance to reseal the engine, because itll never be this easy.
You can use the 7 series intercooler and piping in the 240 and it fits for the most part. A little massaging here and there and itll be good to go.
Get a set of Orange 850T injectors. They are high impedance, drop in to the stock rail and will not require resistors to be wired in like the 7 series have.
