Gen2, LS1 & 4spd

[smccask]

I've scoured the internet, and surprisingly I cannot find anyone who has put a 5.7ltr LS1 in a roadgoing paj. So i've gone out, priced it all up (100% diy), measured, and measured.. And I am sure it will fit and be an ideal motor - i'm using it for towing camper trailer. I am going for Mark's tx case adaptor 23spline, to adapt 4L60e holden 4spd box and LS1 with truck style rear hump sump. Radiator will have to go forward 100mm. Exhaust will be tight, perhaps best through the guard. Tightest clearance looks like a/c to steering box. The legalities look easy for a 4wd - weight similar to 6g72. I think the paj drivetrain is up to the challenge in high ratio tx selections, but would need some care in 4L. i'm doing a 3month trip with paj and camper before I start engine conversion, so plenty of time to determine if a v8 is sensible.

Anyone have any further info or advice on this conversion?

I've got a few questions tho;
1) what pajero's have a 23spline tx input shaft, and which have 24? I know my NH auto v6 has 23, but it'd be nice if I can fit my engine setup to a later model down the track.
2) what is the length from the tx case front face to the bellhousing flange for a marks adaptor & 4L60e combo? I need to know where the back of the ls1 will sit. Should be the same for a commo v6 conversion if anyone has one.

Gonna keep my eye on this one

Don't take it serious guys, but somtimes I can't stop to laugh...
Over 5L engine to tow a camper ROFL
I assume the camper has room for 15 people, a pool and bowling alley?
In the old days a 34HP beatle was towing campers of almost 2 tons in weight - 1.2 liter engine with a crappy carby system.

Ok, enough jokes:
Why go through all the trouble and money to get something like this into a 4WD?
Apart from the engeneering side of things it is total overkill to me.
If you reduce to a suitable speed for the bush you need really strong and sturdy stuff, using second hand parts from normal road cars is not a good idea.
If you go for more speed and less power you'll wreck you car as you are always tempted to give it a bit more.
Only because you fit something into a car does not mean it will out properly
All the guys I've met so far with big engines in their 4WD are constantly wasting money on repairs and upgrades the would not need without the mods - so is it really an upgrade or just a good way to burn hard earned moeny ? LOL - as I said don't it too serious, I just think it's funny like having a motor bike with over 200HP that you can't handle anymore.

There is a whole automotive market that you clearly do not understand, but it is mostly for fun, and not practical, so I accept your criticism. Thanks anyhow. Anyone else?

My turbo subi 69 kombi was the most fun car i've had, engine conversions are great!

[schnitzel]

there is currently at least 3 x ls1 coversions being done into l400 delica's so the bits to do it are out there, there is also a 2uz fe twin turboed conversion into an l400 that eats the LS 1 for breakfast.

3.8ll and LS1 engines with the 4l60E gear boxes already have someone making kits for straight installs... see link below... you can talk to them in person if you live in melb...

i'm putting a GTO engine in my pajero shortly, just for pure shits and giggles, if i'm getting close to 15lt+ average to 100km, i might as well drop something into the engine bay that i can at least justify where my fuel its goin ie: turbos/supercharger/V8...

there is also a mob over seas that does the conversion kits for the Lexus V8 series into the Paj... apparently we use the same gear box centers and gearing "apparently" ....... old saved link died though...

Dis regard first half of my post... posting on cell phone couldnt see full first initial phost

gearbox length

just for the record,

Pajero V4AW2 length from bellhousing flange face to factory TX case adaptor rear flange face ~660mm

The holden 4L60E i measured was 565mm from bellhousing flange face to rear flange face (not including extension housing)

Marks adaptor between 4L60E and tx case is 130mm, so the bellhousing flange will be 35mm further to the front of the car

I still can't find info on which pajeros have a 24 spline tx case input and which have the 23 spline - so if anyone can shed light on this, it woudl be appreciated.

i have put an ls3 into a GU patrol using a marks adapter's kit. and the end result was quite badass, nice simple motor, lots of power and tourqe! BUT, patrols have quite large diffs and drive-line components so its sensible seeing one in that sort of bugalug plate of porridge....

Pajero's are more lightweight, I think you'd be better off with a VN commodore v6 motor. or an ecotec. as this will stop you from having to move radiators etc. you can always get standard superchargers for the ecotec's which sound very nice! and would have more than enough power for a little pajero.
Also parts are cheap as chips... there are endless pro's to choosing the v6 over the v8 for this application.
if you put a v8 in the Pajero you will always be un-satisfied at its performance, first it will be brakes, then body roll, then driveline woes, then diff ratio woes, then after all that total cost will be around 30g. and youll be stuck with a dirty v8 paj that your unhappy with.

Im not trying to be a wet sock, just trying to let you know its not all about how big your engine is. but want always overpowers need. lol im not perfect, only way ive learnt is going down the road your about to.
good luck!

[smccask]

Thanks for the first-hand experience NTPadge. Yeah, the 3.8 is very much the sensible choice, and the cost is so low. But my problem is that it is just another v6. I've had v8s in the past, and there is something about the sound that makes me want one in my paj. I've considered the other obvious v8 options, and I find the LS1 the best fit in all categories except a little excessive in the power department.

Has anyone experienced the 3.8 commo v6 in a gen 2 with GM 4 speed? How does it compare with the 3.0 and 3.5 mitsi motor? How does it tow?

[NTpadge]

if you want a v8 in the paj, why not start with finding the smallest one or atleast one with a narrow angle, like the ford 302 out of the ed falcon... its a narrow V so will have less fitment issues, parts are cheaper, can make it look like an old badass thing with chrome rocker covers etc, with a street cam, edelbrock dual tunnel ram intake and twin holley 600's it would sound so godamn good... and you would get away with it cheaper than an efi engine conversion as the wiring issues are done for. or you could just leave it stock ford fairlane style.

[peejay68au]

There's always the 4.4 out of a p76. Lightweight and can produce lots of power.

Without EFI, you'd have a snowball's chance in hell of getting it engineered.

I too have been doing some homework on the feasability of an engine conversion, as it seems every engine builder wants to give you a touch-up to rebuild the 6G72. The Mark's kit seems to be specific to the 2.6LT petrol and the diesel, so not only do you have to source the engine & transmission, but 4cyl or diesel transfer case.

ive got a vx calias with a few mods on it 10lb boost ,191 rockers ,cold air intake,extractors,it will eat most v8s easerly of the mark to 120 ks ,you can do these mods for less than a grand
