I tried digging around and found several posts regarding this mod, but none specific enough to my situation.

I have a 93 850 GLT 5sp NA and was just given a totaled 96 850 LPTurbo auto. The engine in my 93 has significantly fewer miles on it, but the 96 was a good running car before it was wrecked.

I would like to install the exh +turbo, intake and intercooler on my 93. All the parts are good form the 96, I am just wondering what other parts are going to need to be swapped; IE: ECU, egr?(93 does not have one), wiring harness, injectors?

Is the 96 even compatible with the 93? Am I looking at a CEL Code nightmare? I am a competent mechanic, but swapping performance parts can be muddy waters.

Any help would be greatly apreciated, or if there is a detailed thread or website thaat can help me, I would apreciate it. If you need more information I can easily supply that as well.

Thank you!

 

I haven't done one or know of anyone that has.

But you will need to transfer almost everything from the 1996 to the 1993. I think you would also have to tranfer the OBDII wiring as well.

 

i'm doing a simular project at the moment,the best and easy way out would be to use the con rods out of the LPT in your motor and regards ecu,get a good piggyback system and boost no more then 12psi.
There you go done

 

My thoughts -- r213faq

You are fighting against several things -- other than proper boost levels...

Ignition timing really needs to retard under boost -- your factory 1993 GLT ECU can't do that.
Ignition timing really needs to advance under decelleration -- your factory ECU is already doing that.

Other makes of cars have boost compensating fuel pressure regulators. The fuel pressure increases 1 psi for each 1 psi of boost -- such that fuel pressure doesn't drop during boost.

My reply to someone who had...
a. OEM ECU for managing injectors
b. MAF intercepter custom MAF map for adjusting MAF signal to ECU
c. MSD Boost Master for managing ignition timing
d. Larger fuel injectors
e. Bosch RRFPR

A few thoughts for discussion...
1) Turbo(s) place a lot of stress on exhaust valves. I don't know details of OEM N/A exhaust valves. You may need to replace with Stainless Steel Exhaust Valves.

2) From what I've read on other forums, the MSD Boost Master is very slow to react to changes in boost. This problem may have been corrected by MSD. This is something that you should investigate. How quickly is your ignition timing retarded when you go into boost?

3) It may be worthwhile just to simply eliminate OEM ECU and MSD Boost Master and replace with a nice aftermarket ECU. Instead of attempting to fool your OEM ECU with clever tricks (disabling O2 sensor at WOT and adjusting MAF signal) -- using an aftermarket ECU you can custom/program fuel and igntion with your laptop. Don't forget wideband O2 sensor.

4) Another Fuel Pressure Regulator worth mentioning...

And lastly...

I need confirmation on this, but I believe that the engine block from your 1996 850 Turbo (VIN 57) has oil squirters to spray underside of pistons. Squirters are not needed for lubrication, but rather for cooling pistons and cylinder walls.

I appreciate your ambition and motivation, but you will have to fight against many obstacles to make your car a smooth daily driver.

 

Honestly if you have a good working turbo motor, just swap the motors.

Or sell both cars and buy a turbo model already.

I really isn't worth swapping all the parts needed, because your going to run up the bills.

Items needed
-Turbo
-Turbo pipes
- Intercooler
-IC pipes
- IC hoses
-Injectors
-Vaccum lines
-Water or Oil lines
-ECU from the turbo model
-Downpipe
-probably a upgraded exhaust 2.5" mandrel bent
- Proper tuning, which will be the key in the end for all of this working right.

I know I am leaving things out of the list, but you get the idea. It is a costly mod to do. Go to http://www.volvospeed.com
