bolting on turbo to 2.4 diesel motor

hey all i got a 1987 LN61 4runner with the 2.4L diesel motor (2L). i recently just got a 2.4 surf top mount (ct20) turbo for it. what im wondering is, is there a place where you can buy the manifold to suit my motor, as the manifold which is bolted to the turbo at the moment is different. or do you just cut the ends off each manifold cylinder piece and weld the ones that are off the manifold on my car already. that option would just be harder because its cast steel. could someone give me some advice. i would rather just buy a manifold to bolt up. i tried looking around on the site for a answer for this question and couldnt find anything.

Ends of the manifold to the head on my 2.4 motor goes like this:

o 0 | o 0 | o 0 | o 0

and the turbo manifold which is attached goes like this:

o 0 | o 0 | 0 o | 0 o

if that makes sense.


thanks
Brendan

You pull the studs out of the head, and bolt them into the existing holes that are in the head to match the manifold.

can u actually do that, because i got a friend who has the same motor and has the same turbo and he said he couldnt do it because its not the 2L-t motor its just the 2L motor. and apparently the ports are differnt to the ports on the head, so would leak. so i duno if his wrong or not. i havent really looked and taken the exhaust manifold off mine to look yet. i just noticed that the two manifolds are differnt and his motor is the same as mine.

That doesn't sound right to me, although I have not physcally done it my self, the exhaust side should bolt up you just need to unscrew 2 studs and put them in existing holes in the head to match up with the turbo manifold.

Will probably need to clean the gunk off/out of the 2 unused holes.

If this is incorrect, let us know as others have said they have done it with no problems.

Think your mate is thinking of the "L" motor (2.2 diesel), the 2L (2.4 diesel) should not be a problem.

oh okay. yeah im hopeing its easy as that.

has there been anyone on here who has bolted up a 2.4 surf turbo to a 2.4 4runner motor? who can confirm all this information

I am running a ct20 on my 3L 2.8. I'm guessing the 3l head is different to the 2l so I'm not sure if this applies to you....I had to use a exhaust manifold off a 2LT-E which bolts up and everything lines up as it should. I payed $300ish from memory for a brand spanking manifold.

oh yeah sweet. im hoping there is something like that out there that can just buy and bolt on. saves the hassles of customizing

i really thought there would be loads of info on this. i hear and see alot of the old 4runners and old hilux's going around turbo'd. i just wonder what they did.

From my understandings on a few posts in the toyota section the 3L head is the same as a 2LTE head, it is the earlier (pre mid 85?) 2Ls that had a different head

This is your current exhaust manifold ...

This is what your replacing it with ...

There would have to be I have an older 2L, with the different exhaust stud pattern, and I have a turbo manifold that bolted straight on. I'll have a look tomorrow and see what what brand it is

the surf forum will have something.

the problem sounds like you have the 2l(1) and your trying to fit 2L(2) manifold. they are different heads and i'm not sure that the manifolds interchange between them.
3l, 2lt-e, 2lt(2) and 2l(2) interchange but afaik not with 2lt(1) or 2l(1).

If its a series 1 2L motor you have to modify the exhaust manifold.
There is bolt holes there for studs but is not flat to the manifold as in they are recessed and drilling into the head is a no-no.
I made some tabs up and welded them to the cast iron manifold.
Is straight and flat and havnt had any exhaust leaks.
To the people that say you can put a surf turbo on a 2L they are wrong.
It can only be done to a series 2 2L or 3L.
Also you have heat up and bend the oil feed line and get a double banjo and link into the alternator oil feed line.
Exhaust is totally different.
Fuel needs to be turned up.
But everything else is complete bolt on.

The only complete bolt straight on kit is aftermarket for a series 1 2L.
Safari Turbo or AXT turbo are the only places that make a turbo kit for a series 1 2L that I know of.
Most say 2L/3L but thats series 2.

there are old 4runners that have a 2L-T in them from factory but they are IFS front and imports.
My mate at work has a LN65 hilux import with a 2L-T from factory.
The surf are all imports and have the 2L-T with an auto box.

If they have the 2L series 1 donk then they are aftermarket turbo kits.
No point putting a brand new turbo kit on a 2L, may as well buy a 5L and put that in, will be about the same price and give way more power and torque than a turbo'd 2L will running high boost.

They would be 3L's, a 3L would almost go as good without the turbo as a 2l(1) would with the turbo, most 2l(1)'s have in excess of 350-400thousand k's.

yeah today i took off the air con and brackets to see the whole exhaust manifold without taking it off so i can still move the car if i had to, and i couldnt see any signs of other stud holes, so that idea of moving the studs around is not guna work with my engine. so all i can do is get the manifold custom made? u dont have any pics of ur custom welded manifold with the tabs do ya?

mine runs a mike vine kit using a turbo dynamics manifold

can u buy the manifold separate?

wont fit as their manifolds are designed for the turbo the use, therefore a mitsubishi T04 not a toyota CT20

it a garrett on mine (T25 Flange). The CT20 is a T25 flange isn't it?

the later model CT20A which are found on the efi 2.4's are a square opening on the flange.
The mid series CT20 which is oil and water cooled is a circle opening on the flange.
The early series CT20 is only oil cooled.
It may bolt up but the crossover pipes for the turbo and oil lines will need to be modified.

Fair enough wasn't 100% sure on the CT20s

hey guys , all i did was i got a turbo kit off a surf,
sold the manifold bought one off a 4 runner that had been turbo'd and used an addaptor flange
that you can buy on ebay for like $70.
just have a sus at a 4x4 wrecker thats all i did the rest is a peice of cake.

what sort of boost are you guys running?
