Toyota Previa Swap

Lextreme

Just call me "Lex"
Anyone ever have done this swap? Right now they are pretty cheap and can obtain one for about 2-4k. I also found out it came with 5 speed manual as standard. Perhaps we can swap out the 2.3L with a 4.0L. Here is more information about this classic van.


1991-97 Toyota Previa: Highlights
Previa minivans went on sale in 1990 as a replacement for the Toyota Van. Previa had either rear-wheel drive or permanently engaged 4-wheel drive (All-Tracs) and were offered in either Deluxe or LE trim. The only engine was a 2.4-liter twin-cam 4-cylinder rated at 138 horsepower. A 5-speed manual transmission was standard; a 4-speed automatic optional. The Previa's engine was mounted below the front seats, but tilted to one side in order to provide a flat floor. It's accessible through a panel in the floor or from underneath the vehicle. Fluid reservoirs and other vehicle service points can be reached by opening the hood. Four-wheel disc brakes were standard on LE models and an antilock system was optional. A sliding right-side door and a one-piece liftgate augmented the front doors.

Year-to-Year Changes
1992 Toyota Previa: Previa gains a driver-side airbag, knee bolsters under the dashboard, and a center high-mount rear stoplight, becoming the first minivan to meet all passenger-car safety requirements. Among other changes this year, antilock brakes become optional on Deluxe models as well as LE models.

1993 Toyota Previa: Only minor equipment revisions are made to the 1993 Previa.

1994 Toyota Previa: Toyota minivans add a standard passenger-side airbag and an available supercharged engine for '94. The LE S/C and LE S/C All-Trac models arrived in showrooms in the spring. S/C denotes models equipped with the supercharged version of the Previa's 2.4-liter 4-cylinder engine. It boosts power to 161 horsepower at 5000 rpm and 201 pound-feet of torque at 3600 rpm. Also, the previously available 5-speed manual transmission is dropped, meaning all Previas now feature the 4-speed automatic. Among the other changes this year are a new steering wheel, a pull-down strap on the inside of the rear liftgate, new front buckets seats with adjustable headrests, and a new front bumper and spoiler.

1995 Toyota Previa: The supercharged engine became available on the lower-priced DX model for 1995. This increases Previa offerings from six to eight.

1996 Toyota Previa: For '96, Previa is available only with the supercharged engine. As a result, the number of Previa model offerings shrinks from eight to four, with the DX S/C 2WD, DX S/C All-Trac, LE S/C 2WD, and LE S/C All-Trac making up the new lineup.

1997 Toyota Previa: Revisions designed to reduce engine noise and vibration are the main changes made to the Previa, as it enters its final year of production.

this is a neat idea.. but honestly.. i dont know how feesable an idea it may be..
i've got a 4wd version and have debated a power gainer forever.. but a v8?!..
i dunno.. it just seems to me that there isnt very much room at all
i guess these thoughts will all change when i bring home a 1uz:D
we'll see how the battle goes once i've successfully put one in my 72 corolla
after that i may just get hooked

alright i just saw a toyota van with a v8?.. alright.. i dont know what to say anymore.. that pretty well shut me right up.. while it's a bigger van than the previa.. i dunno.. just seems a little bit of a tight fit.. but then again working on the previa period is a tight job
AAAAnyhow.. i'de LOVE to see someone do this.. and then possibly follow suit on my own van:D.. but first my mango gets fitted...

Fun,

Perhaps you should try it or at least take some pictures of the Previa so we can study it. Perhaps there is enough room for it. I dont know because I dont have a Previa myself.

99% sure it won't fit. The engine is sideways... and the accessories are run off a separate drive system. You'd probably have to make a "dog house" at the very least. I've thought about it... but it definately isn't worth it.

Well, you can still add a turbo... there is definately enough room for that. The S/C versions have quite a bit more pep. A T-28 would be perfect. Oh... 2.4L = Previa gets better mileage than my SC4

Just do it, post some pics up of your progress. Ive thought about doing it myself as previa vans in NZ are very cheap. $500 to $2000
You will need to build a box over the engine and remount the front seats. My advice is to run a toyota Hiace gearbox, this way you can adapt the 1UZ straight on with a celica to 1UZ bellhousing as hiace boxes are based on the W series boxes.

Not to bring this old thread back, but I just got a 1994 or 1995 Supercharged version of this Previa. My neighbor gave it to me for FREE. The van is not running and plan to do something.

1. Get a used imported engine from Japan ($750)
2. Rebuild the motor with forges and turbo charge it.
3. If possible, 1uzfe swap.

What do you think?

You're really lextreme. You always come up with hardcore ideas. They're hard to break, though. I heard the SC Sienna has more problems than the N/A one. Hopefully, its engine is built differently and can withstand 7 psi of turbo/intercooler setup.

well.. i'm not gonna lie.. i like the idea of you putting in a 1uz in one of these
gets me a little curious.. i have a previa van but nowhere near the resources to do something of this magnitude.. once i've completed my current project i'll be looking for something else to put a 1uz in and well.. i've always loved the previa van.. hopefully even get it to work with the 4wd!
really though i'de settle for the rwd version if i had to
let me know how this works out
you've got more of the resources to do it than i do, that's for sure
this would be neat
good luck!
i'm definately routing for you!

Hey Lextreme I was searching for supercharger in regards to my project and saw this post. It's an old post but I have a 98 sienna and have thought of supercharging it.

My previous car was a v6 Solara with the same engine as my Sienna and at the time I had found that the same supercharger would fit both of the cars.

Anyhow just checking to see if you still have the supercharger for your van and might want to sell it if you aren't using it?

thanks,
bmack
