Thinking about this project again. Any comments on this question?Got a 1990 motor coming form Goldwing with 69K on it. Any major differences from 85 to 90 I need to be aware of?

There are no major differences. It should bolt straight in.


Made a bit of progress. Will update pictures soon.
Got the springs and upper control arms in
Got the lower control arms installed
Got the steering rack with new boots installed
Got the axles rebooted and cleaned up ready for installation
Go the transmission resealed, every single seal
Got the motor mated to the transmission
Got the Alternator mount installed
Got most of the under hood sheet metal parts cleaned and painted up in Por 15
Got the front and rear main seals and the oil pump seal installed
Cleaned up intake manifold and the head, pulled the LH stuff in Prep for T-5 Stuff
Looking for a T-5.2 or a 2.1 CPS the hall effect sensor type with the 2.1 pulley
Nice progress! I need to do this with my 70's era T16 swap project... where is Westport PA?
Never-mind - the power of Google maps has answered that question! About 4 hours North WEST of me. lol Bloomsburg is nearly the 1/2 way between you and me.


Thanks, I live just north of the West branch of the Susquehanna on Kettle Creek. No Cell Phone, cable, High Speed Internet, Police. It's nice.
My Workshop It's old and formerly the village blacksmith and carriage shop. The road in front was an early stage coach trail from Westport to Galeton.
If you don't mind a bit of snow, move to Northern Michigan. $200K buys a nice home on 10 acres. No Saab dealer but there is a BMW dealer in Traverse City. You will have high speed internet but that's not a bad thing.![]()


Yes SeveralAny 3+ acre lots of land or homes for sale sub $200K?
No Saab dealers, a BMW?Merc dealer in State College about an hours driveIs there a local BMW or Saab dealership within 20 miles?


Uploaded various pictures of the project.
Got a question regarding the picture of the two pulleys.
The Pulley on the left is from a 91 DI/APC 9K which is the same as the T5.2 it replaced.
The pulley on the Right a 2.1 900 EZK.
I want to go Trionic 5.2 and am wondering if when switching the DI trigger wheel to the 900 pulley do I need to clock it different? The bolt pattern is not symmetrical so I would need to re drill holes to clock different. The 91 was a straight up 2.3 motor the 900 a 90 degree slant.
Still trying to locate a CPS sensor, Throttle Body and a AIC for the project.
Thinking I'll use the newer intake Manifold since it is shiny.


Some progress and a bit of a set back.
Installed the motor mount brackets to the motor and was starting to install the exhaust manifold and found a busted stud Grrrrr. Of to Ace to test their inventory of screw extractor kits and metric taps!
I believe I resolved the CPS question. If you take the T5.2 trigger wheel and put it on the 900 pulley the 3 mounting holes require back rotation of the wheel to line up. This puts the leading edges of the major index's in alignment with each other making it look like this:
Picture linked form 900aero.com
Benefit of using the 5.2 wheel is there are no modifications required.
I also sourced a CPS, AIC and TB which are inbound.
Found a great set of Inca Wheels (my favorite 99/900 wheel) wife likes them too.

Busted exhaust stud removed with an assist from Harbor Freight
Installed exhaust manifold. Gearbox dipstick and turbo later this morning.....
AIC, TB and CPS arrived. Have 3 TB's and 2 intake manifolds and need to cipher on the best franken-mod for my application.


Some Updates:
Got the CPS fitted with the T5.2 trigger wheel also got a mating connector from an old O2 sensor so I can make up an extension to the T5 connector, will look factory and no AC issues - Need an entire C900 AC system though....
Fitted TB from a 9000 with 900 pulley for the throttle cable
Fitted Intake, red top injectors, T5 AIC valve, starter and alternator
Torqued Flywheel bolts, new pilot bearing
Installed T5 water temp sensor
Fitted water pipe from front of head head to heater core junction.
Considering deleting the TB heating hoses as per Mike_D the T5 Guru
Hey I forgot who was looking but there is a 3 acre place with large house and garage for sale down the road.


Last picture is of a T5 head I have, I also have an 85T head. Wondering if I should swap any of the cams around?


Working on the wiring for the T5 swap. Using a 94 9K Motor harness as the donor and it needs mods to work in a 900. The 85 body harness also needs to be stripped down and rotted wires repaired. Small order for motor mounts and shifter pin, and some other things and I can drop the motor in and complete the electrical and mechanical installation.


Wow, just got DSL a huge upgrade from HughesNet.
Making more progress towards dropping the motor in.
These pictures outline the CPS mod to fit the 9000 harness and shorten the lead length. Note the CPS input to the Trionic unit is the same in 5.2 and 5.5 but the Hall effect sensor is powered so you need to cut the brown wire from ground and hook it to the sensor power pin.
Also have new Ebrake cables, PS hoses and motor mounts to install then drop the motor in hook up the exhaust, and shift linkage then on to electrical and fuel stuff, then all the plumbing and the front radiator support. Once it runs I'll get all the new front suspension and brake parts so I can sit it back down on the ground.


Completed successful test of CPS into ECU and T5 Suite. Plan on getting the motor back in the car this week. I installed new E-brake cables and new PS hoses while the motor is out.


The motor is back in the car finally. One of the easiest installs ever. literally dropped it directly onto the mounts with only a small shove on the way down. Rigging the motor on the hoist seems to be the secret to success. Spent this morning hooking up the under car stuff. Shifter, exhaust, Power steering, speedometer. Just need some ball joints and rotors and new calipers and it can sit back on the ground. I really hate working on my back, in my next life I am getting a garage with a lift.
Next up, all the plumbing and electrical completion. The electrical will take a while as I need to splice the EFI harness, mount the ECU, and repair the degraded wires in the body harness. Since I am going T5 I will remove all the jetronic stuff while I have the harness opened up and will re wrap the whole thing so it looks OEM.
Looking good!


Been a while for an update but I have been busy.
Since my car is an 85 I had some wire harness issues.
So I stripped the entire harness and spread it out on a 4x8 sheet of plywood and repaired all the rotted insulation areas. The body harness was no where as bad as the EFI harness so repairs were minimum. High heat and exposure to under hood vapors seem to be the cause of insulation rot. I also found a bad ground lug for the left side radiator fan which caused insulation to melt, worth checking the front cross member ground lugs if you have an 85.
I removed the ignition and APC wiring and spliced in the T5 Harness from a 94 9000. A lot of double checking and re routing of signals. I also used the old system and Fuel Pump relays and will mount them and the T5 box where the APC box would normally go.
I have a few more wires to sort out and when complete I will wrap the entire harness with Kapton harness tape as used in Aircraft. Heat and chemical proof! will also add jackets to single wires that get exposed to high engine heat areas.
I also included some shots of my donor harness from an 86 C900. I am using correct wire colors wherever possible and creating an updated wire list/schematic for when my memory fails in the future. Notice the pile of discarded wire harness "stuff" If you need some plugs or wires of a certain color drop me a PM and I can package it up for you.
