PreRunner Mods

[dhoule]

Hey!

I'd like to turn my black and chrome 1999 Toyota Truck Tacoma PreRunner Extra Cab 2WD (L4-2694cc 2.7L DOHC 3RZ-FE MFI) into a project truck, but there's so many variables I'm not sure if all of these mods are 100% compatible with one another. Here's what I'd like to do...

- Get myself a V6-3378cc 3.4L DOHC (5VZ-FE) MFI engine (about 190 hp)

- Have it disassembled, balanced and blueprinted (+10 hp)

- Add a few TRD components... intake, exhaust, plate, suggestions? (+25 hp)

- Add a TRD supercharger (+50 hp)

- Add a 7th injector (+25 hp)

- Add headers, dual stainless exhaust (+10 hp)

- Probably need a different/upgraded ECM chip to handle the differences due to the injector and supercharger.

- Mate it with a manual tranny. Don't know if this is possible since the PreRunner only came with an automatic. Might be some cabin and center console mods to accomodate the stickshift and new clutch pedal.

Questions...

All these mods are definitely within the realm of possible, right? I mean, there's nothing ultra exotic here is there? I'd be over 300 hp (maybe more) with mostly factory stuff.

Are there any suggestions for trannies? I drive 90% street so off-road isn't a requirement. Don't need or want 4wd. I'd also prefer bolt-on with as few custom chops as possible.

Would I need a different driveshaft? Different wiring harness? HD clutch? Is different gearing available for the rear diff?

Are there any good references or information out there for any of the more tricky mods like the supercharger, 7th inj, chip thing, even Tacoma engine swaps in general?

Considering it's out of warranty now, would you recommend dealership installation for any of this or are all these mods something an average to above average car mechanic could figure out? Which mods would you always avoid doing yourself?

scrap the TRD 7th injector and get the URD kit....you can also skip the intake and do a deckplate mod w/ amsoil foam air filter...gains are similar to the intake plus you save some cash...

As far as hp goes...those numbers quoted and given on sites are for hp at the crank....you lose some through the driveline to the wheels...you'd have to put it on a dyno to see what u actually get to the wheels...

sounds like you might wanna be running at high speeds thru desert or similar terrain...don't forget the suspension....

URD kit?

[snobdrblinkchik]

the URD kit...Underdog Racing Development....it's fuel mods...fuel pump, higher flow injectors, and some other stuff that deals w/ the problem of running lean....check out Gadgetonline.com I think that's the site...if that's not it then go to Tacomaterritory.com and search for URD kit...it'll direct you to the right spot...the TRD 7th injector was just crappy engineering...band-aid for a major problem...the URD kit solves the problem...and it's cheaper

As for the tranny, anything is possible with enough cash....u'd need a clutch master cylinder, clutch assembly, manual tranny for v-6...probably some other little things too that I can't think of...it'd be a lot of work but if you want a manual that bad then go for it
