View Full Version : my new 4runner 3.8 V6

11-08-11, 04:12 PM
picked this up yesterday off a young bloke on ebay
he started a V6 conversion and then lost interest
already has a VP V6 fitted with a rebuilt T700
he bought one of the V6 conversions kits to make it all wok
I just have to wire it up(came with the new loom)
also need to lengthen one tailshaft and shorten the other
and plum up the A/C and P/S hoses all up
already has 2" body and 2" suspension lift
retrimmed interior
roll cage

my plans are
either twin turbos using 2X RB20 turbos or a GT35 single
making the manifolds using thick walled pipe
im leaning towards single just because it will be a bit cheaper
but twin high mount turbos would look fucking sick

single 3" exhaust
modified inlet
33" tyres
tune the standard ECU
vapour injection LPG

Noice, how much moolah did it cost ya ?

11-08-11, 04:24 PM
got it for $3500 which isnt to bad ....trying to find one with the combo I wanted was pretty hard
I wanted black...with flares...V6 3.8 auto

11-08-11, 04:54 PM
Going to mount the turbo over the gearbox? I hear it's the new hotness

11-08-11, 05:17 PM
Good move on the auto. My old moo powered lux chewed manual boxes like expensive cheese.

Yeah the standard 5 speeds are weak as piss
the T700 are the strongest either but better then the manual
plus its better for 4wding
should be ok with a shift kit in it

well finally got her started today
started up nicely but didnt run it for long
shes a bit loud with no exhaust at all :yup:
Im going to get the header flanges cut tomorrow so I can start on the turbo manifolds
and ill take it into work sometime during the week to start on the manifolds etc

21-08-11, 04:11 PM
I still find it funny ARB actually converted and sold 4wd Hiluxs and 4Runners with the 3.8 moo as new cars.

they still had to be better then the 3vz they came with

got a few more goodies this week

28-08-11, 05:25 PM
pretty unconstructive day today
I was hoping to start on the manifolds and I was going to make the flanges but that turned out to be a cunt of a job so Ill just order some tomorrow
got intercooler mounted
and a few other little things
also ported the TB

28-08-11, 05:40 PM
Love the stealth FMIC, looks awesome.

28-08-11, 06:10 PM
But its IFS :fgay::fgay:
other than that, cool little project

28-08-11, 06:57 PM

other than that, cool little project

its will get me as far as i need to go
and if it doesnt i can do a solid front conversion

28-08-11, 08:29 PM
Sas it lock it and get pics of it on 6 stage :)

30-08-11, 03:37 PM
Nice pickup, hard to find em in black.

30-08-11, 04:30 PM
looks like a neat machine

04-09-11, 05:05 PM
little more progress this weekend in between fathers day and my daughters birthday activities
got the drivers side manifold cut and tacked together
and started on the passenger side but ran out of pipe so couldnt finish it

18-09-11, 06:01 PM
manifolds are done
coils relocation started...wiring extended etc
got the cross over/merge made and tacked together
also picked up a garrett GT3540
my stepper gauges finally arrived as well after a month of waiting :mad2:
oil pressure,EGT,water temp and boost
will be ordering the pipe to make the exhaust this week
and try and get it into work so I can finish it off

20-09-11, 01:42 PM
This will be awesome, nice work.

20-09-11, 04:53 PM
Steve, i have a twin cab hilux with a V6 T700, fucking great thing but a diff change is a must or you wont keep fuel up to it...

ive got a diffs out of an auto surf 3.8/1 ratio, 31'' tyres does 2200@100km/h

20-09-11, 07:34 PM
yeah I might have to look into gears not shore what gears are in it atm I havent even looked...33" tyres will help as well
she will be running on LPG too
got a little more done on the manifold this arvo

20-10-11, 08:15 PM
manifold just about done
got a bit carried away with this and felt like binning it.... the $100 worth of bellmounths on it was the only thing stopping me

01-01-12, 05:13 PM
getting close now
IC piping all done plenum done and fitted,turbo and manifolds all fitted
there a little bit of wiring to do fit transgo Stage 2 shift kit and corvette servo
fit walbo pump finish the rear bit of exhaust and im pretty much done
3.5 dump into 3" system
standard delco 808 ecu modified to run tuner pro RT





24-04-12, 10:07 PM
pretty much done now just need to finish the tune and sort what ever little issue may arrive
first attempt at tuning last 1.5 on the dyno before the box died
I sourced a built craigs automatics box which i sent back to craig for him to check over and reco the standard converter and turned out to be in not so good condition so got it all fixed up and put my stage 2 shift kit in to replace the full manual valve body
got it all back in and no 3 -4 gear so ripped the valve body out and put the full manual valve body in
so she is now full manual T700 shifts hard as fuck chirps 32" tyres with under 1/2 throttle on gear changes


25-04-12, 12:35 PM
The cooler doesn't know if its black or white. Temporary cooler location in last pic?

Will being interesting to see how it goes all done. Engine bay looks impressive for a 4x4.

25-04-12, 05:05 PM
yeah cooler is just cable tied there for the moment i want to get a bigger one so i dont want to mount it yet plus I have a engine oil cooler so I have to try and make room for them both which is gunna be hard because theres not much room behind the bar its already 50mm further forward then factory
I wanna get it on the dyno tomorrow thats if I have the motivation haha
its taken to long to get done with all the gear box issues and im just about over it

25-04-12, 09:41 PM
Looks great! I remember Crack on here had some issues with 2 bolt flanges on his ecotec turbo manifolds sealing reliably though and he upgraded to 3 bolt.

25-04-12, 10:27 PM
yeah ive heard that ive used them on other manifolds and there been ok ...see how I go i guess

25-04-12, 10:33 PM
Can you give a rundown on the 808/tuner pro setup you are using? I don't know alot about it but it looks interesting.

25-04-12, 10:51 PM
you remove the eprom and replace it with a NVram board and a coms port and away you go tuner pro RT 5 is a free download an american guy developed it to tune his car he has a web site and forum its all free
the guys on delco hacking made the NVram and com port board it miles ahead of kalmaker
with the these installed you use a custom operating system of sorts called OSP 12P
gives you switchable maps 5 flex out puts choose between 4,6 or 8 cylinder and a heap more
its real time tuning with map tracing even has auto tune just wire you WB02 in and it will tune the VE table
go onto delcohacking forum and check it out if you want to know more

26-04-12, 07:55 AM
Thanks! Did you have to upgrade you MAP sensor?

26-04-12, 06:44 PM
Thanks! Did you have to upgrade you MAP sensor?
yeah 2 bar map

26-04-12, 09:21 PM
pretty solid amount of work looks like it went into that thing to get it up and running. love the manifod idea.

what you mean by custom operating system? as in not windows? how much was the NVram board? sounds interesting... will have to check out delco hacking one day

26-04-12, 09:48 PM

gearbox out again..im ready to burn this:mad:

13-07-12, 10:39 PM
Man that sucks, a bad run with the autos.

Mine has been in there for a year now, and i broke the Marks 4wd Adaptors output shaft last week while on holidays. When it was getting changed the box was in really good condition internally.

So keep at it mate, once you get a good one in there it should last.

im really leaning towards going manual now but dont really want to spend the cash on it
