What would it take to get a tdo5h 16g in and working on a ca18et?
Is it even possible? My friend has one that he's letting go for cheap.
Thanks in advance. Oh it came off of a JDM EJ20

Here is a pic of the turbo

too much!

Custom oil and water lines. Manifold adapter (if your lucky) or a custom manifold. Custom dump pipe.

better of buying a better turbo for the amount of work needed.

good luck with it neway.

What kind of flange does it use?

It's probably the typical trust pattern of a diamond. Need custom manifold. Water and oil you would need new lines made up. The turbo itself should be well sized for the CA tho.

you also will likely need an 02 housing made up, depending on which way you want to point it.

If you want to top mount it, yes definitely. The 02 housing will point the DP right at the hood.

If you want to bottom mount it (like standard) you'll need a custom engine mount (won't clear the wastegate can)

I've had a TD05 that has long been intended for service on my ca18et.

The DSM turbos are very well matched from a performance standpoint, but as a bolt on, no way. A T25 is way easier to install though. A T3 is still easier, because everything is pointing the right way.

Just getting it in is only part of the problem ... keeping the motor from going *pop* with 550cfm of turbo is going to take some work.

Now, all of that aside, there's 2 things

1) that doesn't really look like a 16G

2)I thought the JDM EJ20 came with an IHI VF37 twin scroll turbo

If the flange on the turbo is the same the as the td05-14b, then we could just make a copy of the 14b flange we were making for Mr 200 and you could use it. Mr Bob's MMR company also sells solid engine mounts, so you should be able to clear the wastegate actuator.

You can make a custom oil feed line using AN adapters. This is what we did when I put the T3 on my car. They are pretty simple to use. The fittings are pretty expensive though. You can buy these from Summit racing online. The oil return line is just a rubber hose. You may be able to reuse your existing line (I was able to), or you may need to get a new hose. You can leave the coolant lines off for simplicity, or you can use barded ends that you can buy at Lowes and more rubber hose. The stock coolant lines are all rubber hose, so you can probably just reuse them if they will reach.

You would need a new downpipe. You can buy some steel tubing and take it to a machine shop and they should be able to bend it up all nice for you. Some muffler shops will do this for you as well.

You should be able to run it on the stock motor as long as you keep the boost low. You probably want to shoot for about 200HP at the wheel because your air flow meter will run out there and you will go lean. If you use the wastegate from your T2 you will be at 5 or 6 psi, which should probably be okay. If you know what the wastegate on the new turbo is set at and you think it is a safe setting, then go with it. You can then raise the boost from there with the boost controller of your choosing.

You guys are awesome! Thanks for all the info! And I figured it would take allot to make this turbo work. I'm still going to keep it as an option. But with all the money I'm about to dump into this car I think I will probably just go with a t25.

Mr.200 this turbo was not the stock turbo from my friends Subaru.
And I am pretty sure it is a 16g.

To me that says it came off a Subaru ... and Subies use IHIs. The JDM subie uses a big mama jamme twin scroll ...

But whatever, it doesn't matter. It was more of an offhand comment. I have so many TDo5s around I trip over them.

14B and 16G and all DSM turbos are the same flange.

Oh, 1 = 2 (one_equals_two) I'm gonna PM you momentarily ... gotta figure out where and all that jazz.

I've heard a lot of people don't bother with coolant lines on their turbos.

But I thought that was a bad idea ... I remember the old Maeserati Bi turbos were not water cooled, and burned up regularly.

Not saying I don't believe you ... heh, please convince me, lines are a PITA.

It looks VERY much like the IHI that I have...

Nissan L28ET's (280ZXT motor) had a T3 that doesn't have provisions for water cooling at all. They did come with a little oil cooler though since heat removal now falls on oil and ambient air. That said, both 280ZXT's I bought (package deal) had their original turbos go out, one with a snapped shaft and the other some PO had gotten a Nissan remanufactured turbo...$$$...yeah, that car was well taken care of until recently :-D
A lot of old Nissan turbos I've seen seem to be dead. I don't know if I'd attribute that to lack of a compressor bypass, lack of water cooling or simple neglect or age.
I'd hook up water lines if I had them. That's how the turbo was designed to work.

Yes, it would be better to run water lines to them, that helps cut down on the heat soaking that gave them such a bad reputation in the early 80s, but it isn't required as long as you give the turbo time to cool off before cutting the engine off. It's not really a big deal to run the coolant lines since it's just regular hose (it's flexible), but I just didn't have time since I needed to be at the SE meet the next day and the turbo was already on and working otherwise. Buick Grand Nationals came just oil cooled and a lot of them stick with oil cooled only for simplicity without ill effects, but I would still prefer to have water cooling if the turbo supports it.
