LN61 Surfs -2.4TD upgrading dump pipe/exhaust

[no_8wire]

After looking at those utes, nearly buying one till I found out the auction description was a sack of lies (apparently rusty arches dont mean the ute isnt "tidy" )

I am picking up a LN61 2.4TD surf.
I know that the engines need to be maintained/ cooling system maintained to avoid overheating.

I understand that the stock turbo dump pipe and exhaust is quite restrictive and collects alot of heat as well.

I want to upgrade the exhaust, but what sort of size should I be upgrading to a 2.5" or 3" system?

Also planing on fitting a cheap intercooler as well.

Anything else I can do to reduce the likelyhood of a BHG in the near future?

Will I know that its not a toyota, I am hoping some people on here have either
a. owned/driven a v6 l200
b. worked on them

Basicly im looking at getting a twin cab 4x4 ute since I will soon no longer have my work courier...

I was looking in particular at the 3l V6 L200 around 1992-1996 etc.

Is there any specific problems that these models have?
(eg like the 2.4 hilux...)

mitsi + V6....

do you have to be told not to shag ethiopian transvestites?

there goes your one-eyed toyota love again revvy...

the V6 in the L200 is no worse than say a 3VZ-E in a Surf, at least they don't blow head gaskets and crack blocks just by looking at them.

Anyway back to topic, the 6G72 in the L200 is a proven engine, it's been in the V3000 since 1987 and the base block (now enlarged out to 3.8L) is still in use today in the current Triton ute and Pajero SUV. The L200 V6 is pretty basic, with the early model ones getting a SOHC 12V engine making a massive 150hp, while the later 97ish onwards ones are SOHC 24V and are a bit more powerful with about 200hp.

In my opinion, owning many Mitsubishi V6s one of the only few weak flaws of the 6G72 is the rings and valve stem seals begin to start letting oil escape passed upwards of around 200,000kms. The other series Mitsubishi V6s (ie 6A13, 6B30) don't have these issues, but they aren't available in the L200. Just like any engine, if you cook them or run out of oil they'll blow head gaskets and run bearings.

Parts are common and easy to get, the engine has been fitted to Galants, Sigmas, Diamantes, GTO, Pajero, L200, L400, Debonair, Challenger, Proudia and I'm sure a few others I have missed.

Other than the engine, the L200 4x4 is a fairly capable machine. Granted they don't come out with a non-IFS front axle like some Hilux and Surfs do, but they aren't too bad off road and are fairly sturdy and hard wearing. One thing you will notice with an L200 is there is more room inside, I found the Hilux and Surf to have a too shallow floor.

[Mr Revhead]

no, its the best part of ten years in the autotrade talking
and wtf has a surf V6 got to do with this topic?

[fuel]

Well he's obviously looking at one as an alternative to a V6 Hilux/Surf, and you were very quick to dismiss Mitsubishi V6s so I thought I'ld bring up the fact that Surf V6s aren't exactly reliable either.

I thought I gave pretty comprehensive advice.. unlike you.

[Mr Revhead]

don't worry, i'm not about to recommend a V6 surf for anything other than a 1UZ transplant!
Or a bomb

You thought wrong.

Anyway, getting back on topic again, had a quick look on trademe and every single one of the V6 L200s of that age bracket has over 200,000kms, some with well over 300,000kms, and they're all running fine still, so that's got to be somewhat promising (compared to their Diesels at least..)

mitsi + V6....

...
Well I think that when it comes to car, I would avoid anything that begins with an "m"

However it seems that utes/truck are a different story,
i.e I have a work ford courier (basicly a mazda b series) and that performs well and has given no problems.

Thanks fuel.

And basicly I need a ute but people want stupid money for diesel versions, and I want a reliable engine yet also that has a bit of grunt.

Plus hilux's are a rip...

Like any Mitsi, you have to keep up to date with the maintainence.
The usual problems with them are headgaskets (constant topping up with "water") but most owners as per usual are unaware that there's a problem until it cooks a couple of times, then the waterpump will sieze because the cooling system is over pressurised, the cambelt melts and all the valves bend.
That's probably more common with the DOHC V6s the SOHCs have other problems.
Like anything, do the maintainence and there's no problem.
BTW I've had a 3.5 Pajero, great tow wagon but too thirsty on gas. They'll give any ozzy V8 a good run.

Thats like saying AIDS is no worse than Ebola

I also had a 12 valve pajero, (94 SWB) plenty of grunt to do some 4x4 work, only problems i had was a minor leak from the waterpump and the rocker cover gaskets had gone a bit hard and leaked a bit of oil.
Mine had around 160,000k's on it.

yeah pretty thirsty but if driven gently can return acceptable numbers.
you don't buy a 4x4 for it's asounding economy anyways.


If you dont service it or keep an eye on fluids it will die just like any other car. I believe this is the case with these cars rather than any particular design flaw.

Always found the 4x4 system pretty good, no troubles with the auto from hubs (pneumatically actuated) centre diff lock worked a treat and it was nice enough to drive. Probably a little taily in the wet on seal and loose gravel but that may be down to the mud tyres and Short wheelbase.

The electric window on the drivers side gave up and it has a particularly nasty cable and pulley system, unsure if the l200 would be the same or not.

Over all much better to drive than the bighorn i replaced it with, and more capabe off road.

L200's are also known for needing the gearbox bearings replaced once they get above 250k's
