760t? You can't easily run the motronic. You cash however easily by lh 2.2 turbo computers. And will need to as the injectors are different on turbo cars b...

Slowbrick;104997 wroteYou also need all of the wiring that goes with it. Grab a 6 pack, put on some tunes and settle in for the long haul.

I followed this guide when I did my first 240 turbo build in 2009

Do I have to do the ezk install? Seeme really time consuming haha

Vee_Que

Yes you do. The Chrysler ignition is a good way to blow a turbo car up.

cr80442

Ah ok

Major Ledfoot

That's the EZ-116-K btw.

You don't want a 117.

I was told you can use stock ignition if you retard it slightly, is that true?

Today I'm going to start a legit build thread I'll take photos of everything and I have a good list off all the parts I have also have photos of the 240 and donor cars

By someone on Facebook or where?

Yeah Facebook he said he had done it a few times, I would have to anyway I looked in the 740T and it was missing and I don't wana buy one haha

Alrighty so here is the build thread I've pretty much got all the parts I need. This is what I have, Manifold, turbo (84 garret), 740T ECU, dump pipe, factory front mount and brackets and hot side intercooler piping. All I need is oil lines and cold side intercooler piping. My main speed bump at the moment is figuring out what to do for ignition. Unfortunately, my two donors cars (84 760T and 740T) both don't have an ezk. I was told if I retard ignition timing I can run the stock ignition system. Another thing I'm not sure is what size thread the idiot light sensor is so I can use it for an oil feed. Here are some pics of my parts and the car i'm working on.

I suspect you could get away with retarding it but would not be safe and would limit you a lot in the long run. So don't do it. Someone on here should have what you need, grab all the wiring you'll need and EZK shouldn't be too pricey.

cr80442

Where is the EZK located in a 740T? I looked near steering collum under the dash and couldn't find it. I will probably have to buy one ugh haha. I looked at this thread http://www.turbobricks.com/forums/showthread.php?t=129382 and it seems really tedious. This build has cost me nothing so far and to be honest ill probs take my chances in retarding the ignition timing. Still ill have a look for the EZK next time I'm at my mate's junkyard. Still, need to figure out how to retard it if I do. Also with injectors, I use 850T ones so I don't need resistor pack correct?

Vee_Que

If your goal is to cost nothing. I hope your car isn't your daily driver.

cr80442

Not nothing but on the cheap.

Correct

cr80442

Do they have to be a certain colour? Green red orange etc

jamesinc

Different colours have different flow rates. The turbo ECU will be expecting around 300cc. The red ones from a T5 will deliver 315, which in my experience is fine.

cr80442

I found this ezk out of a 740 16v NA, any good? I have the harness as well just didn't take it out yet

Vee_Que

You need the wiring harness from a lh 2.2 86-88 740, and then a ezk ecu from a turbo 740 of the same car. Otherwise convert to lh 2.4 which involves changing to the crank trigger on the flywheel, and then getting turbo ecus fit them. The non turbo maps do not have mapping to provide for boost.

My car is an 88 so this 541 ecu plugs straight in, now I need to convert my Chrysler ignition to EZK correct?
