Gen 2 4wd system

[dvk-kp]

Hi guys. i just got my hands on a twin turbo GTO for its motor to put into my 91 Pajero its a 3l sohc v6 at the moment so the swap shouldnt be to hard, but what i need to know is if the standard Pajero computer has anything to do with the 4wd system? (or does it have a separate computer for the 4wd or none at all ) i plan to use the loom (engine part only) and computer from the GTO to make wiring it up really easy but wont be able to if the computer controls the 4wd. your input will be greatly appreciated.

Gens 2s have a separate 4wd ECU. Not 100% sure if the standard comp controls anything but I would say it wouldn't.

[dvk-kp]

oh cool. that will make it easy.

nice motor nice easy 400 hp @ 1 bar

[dvk-kp]

lol dont tempt me would the injectors be able to handle 1bar of boost? ive got no idea what size they are. and the turbos are pretty small. i think they are 300hp factory

[vvega]

jap ones were 6 psi stock
nz new ones were 10 psi stock
i had mine running 16 psi .. stock fuel cut is 18 psi
never had a issue at 16 psi afr's were always spot on

then rebuilt it new injectors ecu etc ... 22 psi tdo5's with 22g compressors ... thats when all the issues started ... everything else but the motor kept breaking

id pick 1 bar been safe as houses

[dvk-kp]

oh cool. i will definitely put a boost tap in then. i had a search and i think the injectors are 560cc which is pretty damn big. should be fun

[fuel]

stock injectors definitely aren't 560cc - that's what Evo5+ run. I'm pretty sure stock is 365cc or 390cc, about the same as 1.8 GSR injectors. I have the same motor in bits in my shed, as well as a MIVEC 6G72. Have you put any thought into the RWD water routing setup, and the custom exhaust manifolds you'll need to make?

[dvk-kp]

oh ok. i just done a search and that figure came up... the custom manifolds are no issue as i can make them myself. but im unsure about the cooling system. i was going to pull the motor out and have a look and go from there. hoping i can use my standard pajero one.

The SOHC engines have a different spacing and bolt pattern of the water outlet flanges off the back of the heads, so the pipe which joins the two heads together and flows towards the water pump of the Pajero 6G72 engine wont bolt up to the GTO motor, same deal with the 3.5 DOHC water pipe, the spacing is different (due to taller block for longer stroke) but the flanges are the same - you could cut slices out of each pipe and re-weld to narrow it down.

You should be able to use a 6G74 DOHC Pajero water pump and thermostat housing, but I'm pretty sure a 6G72 SOHC water pump and thermostat housing wont fit between the wider DOHC heads.

I'm undergoing a similar conversion, 6G72 MIVEC + GTO turbos into RWD Galant-Sapporo coupe - http://i97.photobucket.com/albums/l230/te71se/Eterna/DSCF1452.jpg

as for the inlet manifold, if you rotate the lower intake Y-pipe, you'll be able to sit it like this - http://i97.photobucket.com/albums/l230/te71se/Eterna/DSCF1473.jpg - therefore not needing to cut and shut the manifold - however that will place the inlet manifold over top the prettier looking of the two rocker covers.

At least you've got your gearbox sorted - that's where I'm stuck haha.

that sort of custom work isnt an issue. so if i make up the end piece i "might" be able to run a 6g74 water pump and housing pieces and it should be the goods? that would make it easy. and i thought the manifold looked like it could be rotated.. thats good to know. ill definatly be in touch as i go along. you know heaps more then i do. nice project by the way!

[fuel]

Thanks, perhaps I could get you to help me out with fab/custom work as I go along, as I too need to make up exhaust manifolds and sort out the rear water pipe along with modifying my alloy sump to clear the crossmember.

I have access to CAPS (Mitsubishi's parts program) also if you need part numbers or diagrams for anything.

I got a 6G74 water pump that you can have. Its done about 1000km but I thought it was noisy so changed it.

where abouts are you located? i would be able to give you a hand. i havent been taught how to alloy weld officially yet but thats coming. ill be after a diagram for the wiring/vacuum stuff a bit later. need to sus out what i need and what i dont.

NJV6. you have pm

[fuel]

I'm in Hamilton.

[dvk-kp]

bit of a way to send stuff. would be ok for smaller stuff but the big stuff wouldnt be worth it.

[spanky]

for your gear box could you use a v6 l200 box?, they are rwd 6g72.

Have you seen one? That is what he is specifically after but we decided there were none in NZ....

[spanky]

two in taumaranui so they are in nz, my neighbours have one a v6 2wd triton, and king country energy had one as their old meter reader, theirs was the square shape l200 v6, neighbours has a r5m21? box,i think the triton is aussie assembled, try aussie for one as they didnt take the diesel in 2wd so they are mainly v6 2wds,

yep there's a few early shape V6 L200 2WDs floating about with R5M22 or KM132 box, which is nearly identical to my original KM132B 'Starion' box - ie weak and wont stand up to the power. The box I'm after is a later model (late 90s/early 2000s) Triton V6 2WD box, which is a R5M31 which is more or less the same as the beefy V5M31 minus transfer gear for 4WD. I'm certain very few Triton V6 2WDs of that shape were sold in NZ, but there are a few in Australia and they are called the 'MK' model. Another car to use the R5M31 is the Delica L400 2.5TD 2WD van, but they are column shift and would have a different bellhousing to the V6. The only wrecker in Australia I could find which had a V6 R5M31 box wanted $1800 for it, for that money I could get a custom made bellhousing made up and use a R154 or W58 Toyota box - at least they would be easier to find should something break.
