If you are planning to use the complete engine and transmission you will need the complete wiring harness and computer from the '98. The ecm for the Vortec will not work with the stock transmission in the '93.I have a 1993 k1500 with a tbi engine an I got a 1998 vortec engine an I was wondering what am I gonna have to do to put that vortec in the 93 Chevy

Full pumps will also need to be changed as well as multiple other parts.
We just finished a Vortec swap in a '92 that had a 700R4. We swapped the black box ecm for a 0411 and set it up to run the Vortec.
The guy I helped finish this in the end realized he would have been better off rebuilding his TBI or doing a 5.3/6.0 swap.
The only way I would do a Vortec swap myself these days, would to either carb it or put something like a Holley Sniper on it. The Vortec 5.7 weak point was the stupid intake design with the spider fuel injection setup.
My wifes years back was a 2000 Vortec NEW, by 2016 it rotted out before anything else went wrong. My old 95 k1500 winter truck I still have, 200K miles, runs like a champ still. Just click of key she fires up !!While I did like my 1996 Vortec Tahoe on so many years ago, it was new and I switched to another vehicle before any problems and I will repeat myself here. I wish I had that 96 Tahoe back. BUT, the TBI engine were rock solid and so was the fuel systems. Care and maintenance is all they needed. My girl's 1990 K2500 is a sample of a sturdy solid TBI engine.
The Vortecs are rock solid as well, after you change the spider to the upgrade spider and put fiber paper intake gaskets like the Edelbrock 7235s on it. The Vortecs are very simple as well. I prefer the Vortec to the TBI but I like them both. You can make a lot more power out of the Vortec EFI without changing any of the components than you can a TBI.While I did like my 1996 Vortec Tahoe oh so many years ago, it was new and I switched to another vehicle before any problems and I will repeat myself here.
