Question about 1991 Toyota Previa
I have a 1991 Toyota Previa AWD with the 5 speed manual transmission. I would like to change my original engine for the more powerful 1995 - 97 supercharged Previa engine. Other than changing my computer, is there anything else that i need to do ? Since the manual transmission was not offered with the supercharged engine, will the gearing be a problem ?
Looking forward to your advice ... Much appreciated !
I do a lot of work on Toyota Previa before; including rebuilt engine, swapping engine and transmission and lot of things in between, but never swap a normal aspirated engine to a supercharged engine or diesel. Since i have some experience in Previa, I would like to share my opinion with you regarding your plan to swapping the normal aspirated Previa engine to a Supercharged engine. When you do a swapp like that, you will not only be dealing with just swapping engine, but some wiring, computer, throttle body, air cleaner assembly, extra frame and pulley on the accessory items, transmission as well as a right rear end to get the correct gear ratio to accomodate the new engine and transmission. I can go on even more, but let me tell you this, beside less headache, it would definitely cheaper if you were to find a Supercharged Previa and fix it up. However, if you are totally motivated to do this project, keep in mind, this engine swap will be a long term and time consuming project.l I wish you best of luck and have fun!

I'm thinking of swapping out the auto on my supercharged for a manual so I'm kind of in the same boat. I think you will have a lot of work to do fitting all the supercharger components into the bay of your van. The layout of the accessories is different for a super charged vs non-supercharged. You'd need to replace most of those from the donor vehicle. I'm not sure how the wiring would be worked for the S/C engine since it has only ever been paired with the auto tranny. Is there anyone else that could inform on that point?
