240 mass airflow sensor upgrade?

That might help with the wiring. I had done something very similar about 6 months ago, its running good but i have other problems right now.

Swift justice is the voice of reason here. With the LH 2.0 came a vacuum advance distributor, you can use that without swapping over and EZK, LH2.2 doesn't require a signal from the EZK. You can boost an NA motor its done with the volvo motors all the time. NO need for a larger main fuel pump.
What you will need to do it is, exhaust manifold, turbo, downpipe, piping, preferably an intercooler setup. New injectors. To avoid all the extra drama you can use the ones from a turbo 850. Wiring harness, ecu, 3 wire o2 sensor, maf, water sensor, boost guage will become helpful. I'll think about the rest. Its very easily doable for under 500 bucks and they make good power.
Piston slap what?

That's right. Piston slap become more prevalent with the low friction design brought out w/ the B230F. Unlike it's predecessors, the B230F has piston steered rods as opposed to crank steered rods. Eventually, piston slap can occur. I've seen 'em with as little as 120k have it. The issue was reduced somewhat with the reintroduction of the heavier 13mm rods. Piston squirters introduced w/ the L block helped reduce the problem even further. I've seen redblocks run 60-75k miles after developing slap.
So, VG2323...just what do you mean when you say "older" Volvos? Since the "newest" 240's are now 17 years old...the expression is a little vague. Are you saying K Jet 240's have a lower volume main fuel pump than later LH Jetronic cars?

so if you slap on a 92 940 turbo cyl heads with camshaft and all to an 86 240 wagon, what can you expect? My original head was shot and pick ur part had a 50% off deal and took the heads off of the wrecked 940. Got a new gasket and so far runs nice and smooth. when I did the smog check it came out way low on the emissions(400 ppm too much for Cal smog regs but way under most cars I have owned in CA.
1991 Mazda MX6 came to 3200 ppm
1986 Volvo 240 wagon came to 1444 ppm. go figure

I'm curious about this as well. We've got a jy with such a deal. And ive heard the Turbo can will help me a bit. Also. Can I swap brackets and switch my alternator Ans ps pump? My research finds that 760 had those accessories opposite of my setup. And my ic to intake pipe does not fit.

And yes, you can swap the accessory brackets around...
Will I need brackets from Turbo engine or will reconfiguring my existing brackets do it? And how will the belts have to be long enough to reach around the alternator water pump and crank pulley? Or do I run only one on my alternator?
I have another dilemma, I need to run water lines through my Turbo. Where do these come from on the Turbo models? I'd like to think iys off the hard heater hose that runs to rear of the block from water pump. Sorry about 500 Q's at a time.

Yes i know what piston slap is but thanks for the science lesson.
As far as the brackets the only turbo specific bracket I can think of is the bracket that holds the turbo to the block on some models.
As far as the water cooling for the turbo it depends which one you have. I have an oil only Garrett turbo but the Mits ones do have water cooling. You can pull the necessary piping off a 740t. I honestly would just run a Garret if you shop smart you can find a decent one for 100.

Got the Turbo with the rest of the goodies. Pretty sure its thE factory Turbo. Its Garrett t3, .42 a/r. Has coolant lines as well as oil so ill run some. I printed some diagrams from alldata, not as informative as I'd hoped for but ill pick up a Haynes for better wiring diagram, as far as the accessories ill have to do some measuring, the Turbo 740 had an offset water pump and the belt ran ps pump and water pump. I will need similar .
One thing that often gets overlooked is fuel injectors. The n/a cars use high resistance injectors and the turbo cars use low resistance, higher volume injectors. You can either use the "green top" standard turbo injectors and wire in a resistor or go with similar volume high rez injectors. As long as they are the Bosch style and similar flow rate they'll be fine. I have diagrams showing how the resitor gets wired in. Most people use the o.e resistor pack, but actually, a Radio Shack resitor can work just as well.
I have the green tops, fuel rail, and fpr from the donor car. I think I have the resistance box but upon looking at the diagram I think its for ignition system or something else. Please pm me the diagram if you have it. I used alldata, it was less than amazing. So if I'm understanding this correctly I still need the resistance with the Turbo fcu? Believe its a 541. I'd have to look at it again don't remember off the top of my head
Yes, the 541 was the factory turbo ecu for LH2.2 When they failed, the dealership always replaced them with the 591, slightly more reliable and has a removable eprom so easier to be chipped.
Here's a pic of the resistor pack, they're located on the driver's side strut tower...

The ecu doesn't dictate high or low res injectors...all the ecu's require high resistance from the injectors. Volvo chose to use low rez injectors for the turbos, so you have to make up the extra resistance w/ a resistor inline.
