LN130 Surf Help?!

[crushers]

no offense was taken, i am just a miserable old .
in all seriousness, till you try the pyro you won't understand the peace of mind it brings.
if you are climbing a hill and the pyro is heading up what can you do?
-let off the throttle, even 1/4" makes a difference to the amount of fuel being injected.
-down shift to a lower gear, higher RPM = quicker purging of the hot gasses = lower EGTs.
-turn back the fuel screw a hair

cheers and report back your findings

thanks boyo thats EXACTLY how i wanted to do mine, i found that image on goodle search and got that im my mind, its super tidy, good job! also thanks for the EGR advice ill do that now, ill block it off with a bolt or somthing.

yeah i was going to take his advice, ive already done 4 of them and are working on a 5th and i really apricate the advice as he is much more knowledgeable than myself, im just a measly peon! but it seems as though i offended him , which wasnt my intention at all, seems that what i said didnt quit come thru in text as it would have thru speech, so ill try and rephrase... if i fit an EGT gauge how will it help? ive seen people say you use it like a tacho, but i dont realy understand how, surely if ur driving up a big hill and ur EGT is getting up there, u cant realy back off to bring it down especially on the highway? And how is buying a EGT gauge going to benifit me more than additional cooling equipment? (i hope thats better, i didnt mean to be ungrateful for advice or offend anyone!)

If i knew how to post more than 3 photos id show u the intercooler unit i have and am going to use, but im not sure how to have more than 3 attachments on my profile (im NOOB) thanks for all advice so far people.

nice, i just read ur write up and im going to follow it word for word, good job. love the bit about the girlfriend lol, mine would probably manage to take her arm off though! im even going to use the same scoop (trooper=bighorn over here) i thnk my cooler is alot smaller, it measures
H=200mm
W=350mm
D=65mm
Inlet/outlet=52mm OD

the only problem is ive not had a body lift (yet) only 50mm spring lift, so im going to have to try and make it fit without that additional room, wich may be and issue...

 

[BoostingLux]

thanks ill look into getting one asap an ill let you know what i find, unfortunatly my truck is "automagic" so i dont have as much control over gearchanges as you lucky boys with manuals...

 

[BoostingLux]

also, i have a roll of heat wrapping for exhausts lying around here from one of my other cars, i was thinking about wrapping the downpipe from turbo as far as till its out of the body. also my top turbo heat sheild has gone walkies so ill make a new one up. Crushers, you recommend a boost increase? how much would you recommend, i see people have 2LTEs free boosting (no wastegate) on here! im not sure if im that keen but im looking at a manual boost controller i have in the garage and wondering if its a good idea or weather itll just turn the engine into a grenade?

A body lift will allow air to flow past and around the tranny. The autobox is a very close fit in the tunnel, and heat build up is an issue. A 1'' body lift is very easy to do, and quick too.

Fit an additional tranny cooler - they only cost about £20 on ebay. After I fitted mine, I never heard the aux. fan come on - which it always did beforehand.

Rip into your truck

Fit neatly in front of radiator

 

[Toyo Boyo]

Fitting a pyro will change the way you drive.

With an auto, uphill you can turn off the overdrive. When towing, I did this every time - it stops the box from hunting between gears.

Then, by feathering the loud pedal, you'd be suprised how much control you will have over the gearbox. You'll get used to it soon enough!

I wouldn't mess about with the wastegate - I'd leave it stock.



EDIT - Without a body lift, the intercooler will probably sit on top of the oil filler. Fit decent quality spring clips and you will be able to pull the cooler off quite easily to allow oil fills.

EDIT 2 - You won't be able to do much with the boost - it'll go up to about 12 psi then start to cause all manner of shyte with the ECU. And you really don't want to be pushing that LTE too hard now, do you?

 

[BoostingLux]

nah i dont wanna push it too much, im onli running about 7psi now maybe 9 os 10psi wouldnt be asking too much with the intercooler on too.

autotrans coolers are alot more over here, the excange rate is onli 2.1 to the pound i think, but the cheapest one i could find new over here was $140. and i cant find any 2nd hand ones.

where would i find the gear to body lift? ive been looking around and cant find any. I removed the vaccum to the EGR valve today and the engine seems to run smoother, not by alot but its noticable, or i think it is anyway. seems to accelerate a bit better too. How to i have more than 3 attachments (photos)? i wanted to post pics of my intercooler but dont know how? if i delete one of the attachment photos (the ones at the start of this thread) will it delete them off the thread?

 

[crushers]

i have run the 2LTE with no waste gate and they max at 14 lbs. remember the only time you will ever see 14 lbs is when you are pushing it HARD. most of the time you will be doing 6 lbs at highway speeds and 10 if bucking a head wind or climbing a hill.

 

[BoostingLux]

so if i use the boost controller i have and set it to 10psi i should be pritty safe all round?

 

[crushers]

set it at 12 psi,
remember the more air the lower the charge temp.

ok ill try 12psi n see how it goes, u sure that wont be putting too much strain on the engine? i was under the impression that the higher the PSI the hotter the intake charge due to it being compressed in the turbo, hence the need for and intercooler?

 

[crushers]

after 14 psi there is a concern but not before that ...

I have had a 2.4LTE that cracked its head (Wayne, I know this also is your favourite Toyota lump, ha) I would do all I possibly could to cool things down, BEFORE doing anything that may introduce more heat into the engine.

The autobox cooler is in the bottom of the rad, and dumps excess heat via the engine cooling system. Not good if you are about to start pushing things with extra turbo pressure. On an engine well known for having a weak head.

Do the intercooler and the tranny cooler (and of course all normal maintenance, and every other cooling mod you can think of (entire cooling system flush, new thermo, rad cap, etc)).

Otherwise the next thing you'll be asking about is 'does the 2.8 litre head fit the 2.4 litre engine'.

You can buy me a beer when I am in NZ for the Rugby World Cup because you will be asking the above question!

(Any beer will suffice)

 

[crushers]

see, that is the misconception of extra boost.
extra boost does not create extra heat unless more fuel is added at the same time. these are not gasser engines. with a gasser you create more heat the leaner the fuel mixture is. with a diesel the opposite is true.
install the pyro, don't change the fuel settings, increase the boost and watch the results.

2.8 head is not more resistant to cracking, they share the same design flaws and they DO crack as well...

 

[BoostingLux]

ill up the boost to say 10psi once i have fitted the intercooler. ive already done all the other cooling maintainance stuff, just waiting for a fan shroud to come, and gotta go pick up and electric fan, im gunna keep an eye out for an autocooler, but unless one comes up 2nd hand i cant really afford one at the moment. if your here then sure ill buy you a beer n take you for a cruise in the redneck rampage haha. all the games are now in auckland where i live as all the christchurch games have been canned due to earthquake damage...

i hear you crushers, im just a tad concerned, this is my first diesel vehicle, and all my previous experience has been with petrols, and if i had a 2litre turbo petrol, i wouldnt even consider doubling the factory boost setting without some other serious mods, but hey, you know more than me, if youve done it then clearly they can handle it. did any of your free boosting LTEs blow heads?

EDIT:
i also hear you boyo, a good friend of mine had a truck the same as mine exept manual, and he never went off road and drives like a 94 year old woman and it still cracked the head, these 2LTEs seem to be eather bullet proof, or pieces of turd. and you cant really tell till its all over. bit of a gamble really *que 'the gambler'*

In complete agreement - I was thinking more of the fact that a more powerful engine would be sending more energy through the drive train - esp. the autobox - needing more excess heat to be dumped into the engine cooling system. I think the auto really pushes this engine over the edge. But as stated, manuals (without the bottom rad. tank) also blow - just not nearly as often.

The 2.8 head fitted to mine was still flawless after 200,000kms in 5 years - not too bad.

I've heard about Christchurch - I'll be flying into Auckland, staying in Palmerston North, following Wales around the north island. WOOOP

 

[BoostingLux]

palmy is a long ass way from auckland.....

 

[BoostingLux]

WTF?

i took the lux out to the forest today and the 4WD started working again! all on its own high and low range worked flawlessly and all hills and the beach were conquered.. who knows what was going on there...

 

[2ndGenToyotaFan]

Well that's good news.... Though I hate it when stuff like that happens.....

 

[BoostingLux]

yeah me too, coz u never know if its going to happen again at a real s***ty time like 3/4 up a big hill.i think it may have been the main relay for the 4wd, coz i took all the relays and fuses out and sprayed them all with CRC to keep the moisture out in the future, and i think that fixed it!? yay!!!
