Pre-runner Toyotas are VERY popular to build. You can have a very good pre-runner, even with a 4 banger motor. Although you'll eventually be craving the bigger horsepower in an engine swap later on in life, the Toy 22RE is a pretty good setup anyway.
The killer setups for Toys involves that you take off your "lift". There are a number of companines which make long travel kits for Toyotas. There's ATS RACING
-- the only complaint I've really heard about their product is the welding "look". Doesn't necessarily mean the quality is bad. Then there's Total Chaos' long travel kits, found on BAJA CONCEPTS web site
. Have heard many good things about these kits. Too bad I got rid of my '90!
With these kits you can get about 10-12" in real-world wheel travel, and still keep your 4x4. You'll need to buy longer front half-shafts, most likely from a T-100, and would be a good idea to get some Porsche 930 CV joints to eliminate any problems with angles.
In the rear there are many choices as well. Speed costs money -- how fast do you want to spend? If you are not planning on turning this into a racer, bound by rules, then you can either go with better, longer leaf springs from companies like National Spring in El Cajon or Deaver Spring in California. Either are very good companies, Deaver being the less expensive depending on what you get. Or you could go with some sort of three/four link with coil overs, or you can go with swing arms. Sky and wallet are your limit. Most go with the springs though, due to cost and ease of installation.
You can also go to SWAY-A-WAY
for thicker torsion bars to help you keep from bottoming out. Their 300M torsions are awesome, just a little rough on the kidneys on the road! [img]/wwwthreads_images/icons/smile.gif[/img]
Finally you'll need GOOD shocks. You can go with something like dual Bilstein reservoirs up from (you have to have a shock hoop made which will accept heim ends -- only way to go!) or you can spend the very little extra cash and get some Sway-A-Way or KING SHOCKS
. They are both the same concept and design. And you'll only need one per corner!
Hope that helps you out.
