Offer it up for a good deal, and someone may pick it up and use it properly.
If certain parts need to be separated, see if you can find homes for all of it at the same time but that's an ideal scenario.
I'd vote for a 4g63 because of overall cost, but you should keep the fuel rail amongst some other 4g61t specific parts.
If you like shifting higher in the RPM window, a 4g61 will win for Zing factor, but the 4g63 makes for a more potent/torquey bottom end, and
you won't need to shift as high, thus saving syncros during daily use, even with high end GL4 synthetic oils.
A stock 4g61t is pretty sluggish, and tame. Waking it up with 1G bolt on parts and cams, would make it worth while.
Thanks for the input. Brakes and suspension are all completely rebuilt. O always do motor and tranny last on all my builds. I want this to be special. Its probably my last project. Im gonna go with a 63t. Now, to find the right one.
A stock 4g63t would be decent, and will knock your socks off once it gets the bolt on treatments and a tune to match.
In simple form, you will still find ways to outdue this outdated suspension, with little effort.
Basic motor, get it running and running well with proper tune-up parts.
Go over the whole car, for wiring and suspension and brakes.
Consider upgrades last, or the car will not likely be able to handle the new found power.
These are thoughts I had years ago, and they ring true for me today, as I sit debating more suspension tweaks and such.
Moral:
You will have fun with either motor.
