Question 87TII to 89-91TII

Please help me, I have an 87 TII that blew an engine and rather to rebuild the one for now, im just going to get another engine. I have found a 89-91 turbo engine, but the dealer said i might need to do something about the oil metering system because it is electronic on the newer engines? What could or can i do to my oil metering system? new parts, modified parts, parts off of the 89-91 rx i could use?

Thank you everyone!!

i Think, and i stress think, that the 5th serise engine uses a diff ecu, and and that ecu moniters the omp and all that other stuff that the newer moter has,

wonder if you could just Yank the OMP, use your 4thS ecu so you dont get waky errors, but im still new to this. so you should probly wait for other replys, and not just use mine

Yea, From what I've read, I can just swap the front cover off of the series 4 motor and put it on the series 5 and use my series 4 ecu and OMP...
Thanks a lot!

injectors are different too. One of the motors is low impedence, the other is high impedence. Don't know what that means, but they're different. There's also some differences.

Now, if you want to sell me that Series 5 (electric OMP) engine, I'd be willing to buy it from you for around a grand. I need one for my '90. You would be my BEST FRIEND if this motor has good compression and no problems, and if you sold it to me.

Sorry The 87 13b actually blew a O-ring and looks pretty ugly on the inside, a couple of the seals on the rotors were stuck, water passages had all sorts of gunk and niks in them. I'm thinking of rebuilding, but i don't have time or $$.. I don't have the series 5 motor, but to soon.... If can install in 87 TII without much hassle!!!

I paid $1900 for this 87 TII with cut springs(lowered), some shiney rims and 106,800 and it died at 108,300, think i paid too much!? What can a TII with no engine go for??

Thanks...

not a *whole* lot, but better than the other FC's. Put it this way, if you part it out and get decent prices:

- TurboII hood $300
- TurboII transmission $200
- TurboII engine core $200
- TurboII wiring harness $100?

This is all stuff people want, so selling it wouldn't be that hard, AND you'd still be left with the chassis with its 4-piston brakes, larger wheels/tires, and all that jazz.

i have the 89 T2 motor in my 87. its not really that much stuff to swap.
1. upper and lower intake manifold.
2. front cover
3. injectors
4. water pump

thats pretty much it i think. the upper manifold on the 89+ has the double tps on the throttle body, and the upper 87 doesnt fit the 89 lower. the front cover of the 89+ has the elec omp and the 87 has the mech. omp. the injectors are different resistance and the 89+ water pump wont clear the 87 front cover. there may be some more little things like that, cant remember. did my swap a while back.

You are referring to the fuel injectors, and not the oil injectors right? I have an 87 engine that has the injectors and those should work, as for the waterpump I would have to buy one and mod it? The 89 has 2 trottle position sensors on the throttle body? So I would need a 87 throttle body? But does the 87 T.B. fit onto the 89 intake manifold?

Thank you very much!!

correct, the fuel injectors. the oil injectors are the same, however you will have to hook up the lines from the mechanical omp on the 87 front cover. you dont have to mod the water pump or anything, just use the 87 one. i was told the 87 TB will not fit the 89 manifold so i swapped manifolds. but i may have been misinformed. the only thing on the 89 up you should grab is the intercooler elbow. the little metal corner piece that goes from intercooler to TB. its a little bigger and flows a lil more. is your current 87 13bt complete? you have all the stuff to swap over right? if you dont, consider finding a 89+ harness and ECU. pull the 87 stuff out and install all the 89 stuff. the ECU/harness swap is easier but its harder to get the parts and more expensive.

what can be done to change the impedence from the ECU? So I don't need a 89-91 Intake manifold, or TB? Just injectors, and front cover and maybe water pump? Appreciate all the info!
Thanks a bunch!

to put in the 89 motor while keeping the 87 harness you will need upper and lower manifold, front cover with mech. omp, and water pump. to change the impedance on the injectors you will need to wire resistors into the injector wires. if you can track down an 89+ ecu and wiring harness then its a straight swap. but its hard to find in good shape and cost $$.
