Need some ideas :)

For a 1992 Previa RWD
What are some parts that I should try to go with first cause the only thing that I have in mind right now is suspension. Any Thoughts?

For Suspension.....I would reccomend going Air.  Air Runner has a kit out for the Egg but I do believe that it is not a Direct Bolt on Application.  I am running a Silkroad Coil-Over/UAS Set up.

The Cheaper route would be do just Springs or Coil-Overs(there are a lot of applications for the Egg).....I found that after running my Coil-Overs at "Full Low" I felt the need to go lower.  Save your hard earned money and go Air the first time around, your Wallet will thank you for it later.  

Good luck with what ever route you choose to go with.

first off if you have any resources to do this try to source a independent rear suspension from japan (the only way to get camber and get "real" low), then get coilovers (if money is no object the k-break ones are the best), and wheels.....

Have a look at other places for the IRS too.. We got IRS on our GL-X Previas here (Called Tarago's in Australia); though i am sure it'd be cheaper to get them from Japan. But if they had them in Canada or something like that it might make it easier to find.
 
I'd be doing something like that too. I see a few of the bagged Prev's on here and always think to myself "that slammed height is higher than my ride height"

IRS swap is no where to be a bolt on deal, if you know how to fab stuff then it's a cool project otherwise be ready to spend some money to get it done. you have to cut some body panels and then fabricate all boxes and 4 point mounting location from Scratch but again gotta pay to be cool or be the guy and do it :dance:
 
About the suspension I have to agree if you don't want to go air right a way, get some used coilovers run them till you get the rest of the parts and then you can go UAS like most of the previa guys. ACC kit is a little bit pricey but much better ride but again more than double the price of UAS. 
 
if you do a little search on this forum you'll be surprise how much cool info you'll find.

I will take a look into coilovers and maybe the Air Runner Kit or UAS. I know mdenoga has it on his but does anyone else have it? I will also take a look around for some reference pics so I could see ride heights etc. Thanks for the infromation so far guys :)

I am glad to hear you're thinking about suspension first before anything else. You'd be surprised how the whole vanning see will be going soon especially Previas. Its spreading like fire. hahaha

Anyways, if you decide air look into getting a custom "watts link" system to help keep the rear axle centered. The lateral rod is somewhat useless in my opinion so I didn't even bother to install it. A fellow member may be able to help you out soon enough though.

And the good news is that 91-93 models, you can access the top of the front struts more easily then us with 94-97 models. Let me know if you need any help. I still have my Toyota Previa Factory Manual as well as a database (specs for torque, fluid capacity, fluid type, etc.) for the family's auto repair shop.

And also its not cheap to modify this van if you haven't already figured that out. =p

The Watts Links is the "best" way to go but it is not needed as you can only go "so low" before you bottom out on the rear arms.  I have the Lateral Rod and have my set up where she is "centered" at my ride height (which does vary).  Getting the Lateral Rod and with some cutting of my fenders took care of my "tire shredding" problem.

IRS...........that would be sweet if you were to go that route.  Many have "thought" about it but as far as I know no one has done it "yet".

+1 on not cheap to modify the Egg, but even worse is that it is not exactly mechanic friendly.  If you don't do the work yourself you may find that you will be paying more for labor than the actual parts.  "Everything" is not easily accessable.

Well I have OK rims ready to go on but I dont want it too look to high haha. Well I think I'll be noticed if I get the previa to look out of the ordinary and just telling people my plans and ideas got them thinking that I must be crazy lol

Please do share of what type of wheels you got.  Also what are the sizes and offsets?  Depending of the sizes, offsets and rubber size, if they are not aggressive you may even get away without even having to run a Lateral Rod and not rub. 

My wheels are a little on the agressive side and that is why I needed the Lateral Rod, Cut my Fenders, Buy Overfenders and Buy a "Extended" Sliding Door Hinge.....just to make my wheels "fit".

Just some SC430 rims 18x8 not bad for less then 200 :P

Yea, some people don't get why we mod vans...haha.

yeah I just showed my friend a pic a previa and he said "what? your gonna rice it out like that?"
