Joel owns a 91 Runner , stock 3VZ .


out 4bying , did the "hydrolic" after market engine option ..



brought it to us for some inspection and advise . With out question , I suggested the 5Vzfe , and promptly showed off the Trekker and gave him a quote on the job . SOLD !

so now starts the work .

Install parts include 5Vzfe , 2nd gen TRD supercharger , URD pullies , 7th injector and some guages , including wideband , thorley headers , with our own "flavor" crossover , our own stage 2 clutch (300HP rated , including NEW flywheel) +our HD rad +++
also complete hi-clearance body mods and SAS .. but that will be later .

Lots of parts ariving






.

 

started yanking the old out ..





and the tear down , Joel wasnt kidding when he said the engine had an oil leak and a knock









.

 

have been doing a little here and there , but nothing really worthy of posting . Today I was able to get a little more done .

Tearing down the engine for some maint. parts , general cleaning and crossover build





cleaning and sandblasting .....
some pieces I'm painting



some of the pieces I'm going to be using "shark hide"



and now with the headers in position , I can start on the crossover






.

 

more cleaning an painting ..




also got the V/covers cleaned, re sealed and gasketed








.

 

got the front end done today ...
all new



and buttoned up



I also neglected to post the pic of my new tool
I built it expecially for the 3.4L



I can now un bolt /re torque the crank bolt on my engine stand



.

 

more "dress up" for Joel



bottom end going together



and also the top end





.

 

little work on the crossover today ..









just "tacked" together .. not sure i'm happy with it just yet



.

 

Looks good! SAS and high clearance will be sweet,too.

 

There is a market for affordable 3.4 swap headers. Might be worth digging into.

 

^^^ agreed

 

thanks fellas


.

 

ok .. so now with a little modifications to the pipe ( this is why we spot weld first) i'm VERY confidant it will fit .





and with the heat shield





I want to do an actual test fit .. just to be sure , and also build the header/ O2 pipe , before I send it off for ceramic coating ..
wont fit in my ovan ! well not yet anyway so I gotta send it out

also got the front end buttoned up



.

 

Just fyi, you can use the 3.4 baffle. You just notch it to fit the 3.0 pickup and that way you won't have two layers of rtv sealant for the oil pan.

 

yep , I know . I prefure the 3L baffle , as it offers "more" baffeling

if it's done right , you shouldnt have to take the pan off for a very long time


.

 

It baffled so well the 3.0 failed haha!!! 2 layers of sealant is too many in my opinion. But yes if done right its fine.

On the back of the sc there is a brass plug. Remove it and install a barb fitting so you can run the vacuum hose from the fuel regulator to that nipple. Thats how its supposed to be modified according to TRD.

 

thanks .. yes (fig29 pg 12)
superchrger is actually not installed yet . it just "sitting there"
we're sending the nose cone off to magnuson for the rebuild

I will do that as well as the rest when I do the full install


.

 

nose cone off to Magnuson for the rebuild



.

 

test fit time !!







header -- kinda fit -- I had to do the ol' in and out 3 times before I got it right . biggest problem was the driver header angle and lower collector flange hitting the frame , so I had to get that corrected , also had to trim the heat shields on the body , so we dont get any nasty rattling . Good to build the front header pipe now with the wideband , cat and rear O2 and final welding



.

 

front header pipe built with the WIDEBAND O2





sniff sniff



.

 

so with a 4th and final "test fit" Joel now has a custom set of headers . I have about 30 hours building these 1 offs .. but I now think I can comfortably build 5Vzfe headers for swaps (NEW product coming)

anyway .. it's off to ceramic coat tomorrow .









Heat shield is not welded yet .. will do that after
