4d56 non turbo - turboing?

[wildplumdx]

i have a 96 4d56 non turbo and i just bought a turbo for it all manifolds etc But it never came with oil feed lines etc basically just need to find out where the numbers that are labeled go too ? and also have an intercooler as its a pajero turbo manifold etc so can i block off the intercooler for now as i'll mount that at a later date ? i'll post a picture

i need to know where the numbered ones go too what they are etc...?

also can i block off the intercooler on the manifold or will i have to install the intercooler in one go ?

thanks

I've never had a non-turbo 4D56 so some of the following is guesswork!

Probably just as well to mount the intercooler right off, it's not that hard, probably easier than piping the air from the Hairdryer to the intake. The important thing is the oil return line from the Turbo. There should probably be a blanked hole in the Oil filter/Oil Pump housing that has a 12 mm pipe and fitting in it in the turbo version, this is assuming that the Turbo and Nonturbo use the same Oil pump/Filter housing. You'll need some high temp oil line to go between your turbo and that fitting. Main thing is to get the oil out of the turbo fast otherwise it'll burn and all sorts of nasty things start happening accompanied by similarly unpleasant noises.

The one that screws into the head is your oil pressure line for the turbo bearings. Make sure you're getting plenty of oil pressure there. Galleries like that one will block up when they're not used so if it has a bung in it, just take the bung out and wind the motor over a couple of turns. Oil should jet out the hole

The others I'm not sure exactly what they're for. I'll have a look and get some pics under the bonnet of mine tomorrow.

awesome that would be great! also found out i need a different injector pump after looking at pictures as mine doesnt have the circle type thing on top to deliver more fuel for the turbo i'm guessing so thats something else i gotta buy! oh well those pictures would be great anyhow thanks for your time !

I'm with Graham. Put the intercooler on straight away. The heads are marginally strong at the best of times so keep it as cool as possible, particually if you want to run Pajero levels of boost.

[wildplumdx]

cool i'll mount it straight off then, also how do i know how much psi i will be running once i bolt it all up ? spose it will just run factory, thats all i want to run on my non turbo engine dont think it would be wise to run more boost than factory would it ? also anyone got parts as i will need a pajero injector pump also ? and the return sump oil pipe the big sucker, thanks guys

The two small pipes in the pic are sensor lines that run to some sensors behind the intercooler mounts on my Paj. Without the Pajero ECU I'd say they were surplus to requirements and they could probably be blocked off. But as Glen was hinting, an abused 4D56T has the life expectancy of an unexploded grenade. They don't like being overfuelled for instance. Constant charges of black smoke means your liners are being lubed by diesel and you'lll wear 'em out as quick as. So it's a matter of doing everything as right as possible as far as longevity is concerned, but with a bias toward the air.

If there are wires going to the intercooler? which is what I am gathering from what you say - these control when the fan kicks in that is under the intercooler to drag cool air through it.

[wildplumdx]

yup i got a photo of it but i have no idea what any of the numbers are labeled on the picture i've put up can anyone help which ones can i do without ? also looking at the intercooler it doesnt look that crash hot the fins look like there bent towards the firewall a bit but is that to catch the air better off the scope ? well it doesnt look anything like underneath of the intercooler where there all nice and mint looking ? thanks guys

You don't "need" extra fuel with a turbo. The turbo alone will give your engine a little extra power and make it run a lot cooler.
Turning up the fuel is something that you should only do once you've got an EGT gauge to know how much heat you're creating in the cylinders and exhaust.
Too much fuel = too much heat = melted pistons and turbo.

If you don't have an EGT gauge, a good diesel tuner will probably be able to use an oxygen probe to work out how hot it's running and how much fuel is safe without melting anything. The mechanical limits of a mitsubishi diesel are something else entirely. The less power you can put up with, the longer it will probably last.

well i went out and bought a turbo diesel model in the end so no need for the turbo part just need to fit the intercooler too my new truck so just use the pajero inlet manifold and bolt the intercooler up is it that easy also the intercooler has plugs and loom crap, maybe sensors do i need this junk ? intercoolers pretty basic aint it doesnt need wiring up?

also thanks bacon for the info but now i got a turbo i dont need to worry about that part correct ? as melting stuff dont sound good at all!

thanks guys

Good score.
As long as you stick with factory fuelling you'll be fine as long as everything is working fine. Dunno why there are wires out the intercooler, if it's a retro fit you definitely don't need them.

[wildplumdx]

awesome, well one plugs for the fan and another looks like a sensor maybe, really need to find a pajero manual and see what the plugs off the intercooler are would be handy, but thanks for your help ! i'll let you guys know how i get on

[NJV6]

Pretty sure it is the sensor that tells when the fan under the intercooler is to kick in.

[wildplumdx]

ah ok well i'll just wire it up so its always going if all else fails !

[KiwiBacon]

Pretty sure it is the sensor that tells when the fan under the intercooler is to kick in.

So is it a pressure sensor or temperature sensor?

[NJV6]

More than I can say mate but I'd say a temperature sensor as the fan doesn't run all the time?

However I am no expert on them - the 2.8 I bought written off for parts had a good motor and the same setup (in other words - looked and guessed namby pambyish I liked that comment - all good)
