How complete is the motor?
Doest it come with turbo and manifolds?
Water/stat housing is different on 1990 because of oil cooler.
Sensors easily swap.
Ignition coil and power transistor are different on 91-94. 1990 are like the colt.
Cas might be different too.
Tb can be found, but at a price.
1.6l tb should work, its just smaller. You can get it going first then upgrade later.
Dsm motor also has oil pressure sensor. Guage needs to be added if you want to know oil pressure
The motor came mostly complete, i needed to get a tb which i found a 90 tb with black isc and i needed a turbo/exhaust manifold, i had a small 16g setup left over in my garage from old dsm days and its in good shape. Im going to be using the 92 intake manifold because its 2.5" compared to the 4g61 2.25" bore.
I bought a 90 ecu with eprom and new caps
PR 1g fmic kit
new front axels
Started the swap a few days ago, Im going to leave the 92 oil filter housing on the block and go with an aftermarket oil gauge which i dont have just yet, i tore out the 4g61 and removed all the vacuum lines and solenoids including the FPR solenoid (not sure if im gonna get a CEL need confirmation if someone knows), removed the ac, ac lines, and ac fuse box. and filled my existing mounts with window weld to stiffen them up. Im gonna start putting the 6bolt together on monday, i need to remove the balance shafts and do the timing belt as well as install some 3g lifters I have.
Not sure what im going to do about the exhaust, Im crossing my fingers that i have enough clearance to bolt up the existing exhaust, im not sure if its the stock exhaust or not, the car did come with a 14b already installed as well.
the stock fuel pump will have to push the black top 450s on low boost until i gather some more funds i might re-install the fpr solenoid until i get the fuel pump and afpr
gonna see if i can use the 1g starter plate or if i have to use my CSM starter plate and ill post that info later since people were unsure.
the only thing im worried about is the guy was trying to remove the existing flywheel before he shipped the motor and said the motor turned a little bit being that he didnt have the timing belt installed im concerned for bent valves but he told me the valves were shut and the cams weren't installed at that time.
When i was cracking off the flywheel bolts myself i rotated the motor quite a bit here and there but i removed the cams before hand so the valves were closed.
My question is when resetting the engine to TDC should i set the crank to TDC first then install the cams at TDC or set the crank to 90 past TDC (so all the pistons are half stroke and install the cams and set them first? Everything ive read says the set the crank to TDC first but has no mention of making sure the valves are closed because they all assume the motor is in time still...thats not the case for me because the crank has been rotated with the timing belt removed
