300SL to a 240sx

[EliteDriftProductions]

Ok so I was at my local junkyard today screwing around and I couldn't find any 240s anywhere, freaking sucked. But! I noticed this 300sl mercedes diesel and under the hood was a T3 turbo, I think the turbo brand was "AIR" something but it was very very clean and was in great shape from what I know about turbos. But the thing I was wondering is would the turbo itself fit on my 240? i know I would need to buy a housing and such but the turbo itself would it be universal to fit on my car? or just the 300sl?
let me know, just have been wondering.

P.s. if you want to give me :bs: just save it because I don't have time for losers who want to bag on guys who are curious or trying to learn.

Its a T3? Did it look like a normal turbo? If so it should be pretty universal, if its clocked wrong buy a clocking kit and turn the it what ever way you need it. Try and find some specs on it like trim etc.

Could it work? Sure

Will it work well? Probably not. Diesel turbos are funky, especially on the exhaust side of the house.


It's probably an AiResearch turbo, which is made by Garrett. Don't take any thing cast on the side, as that doesn't tell you anything.

In the end, it would easier to source a stock turbo SR setup and swap on, and much less aggrevation.

Air Research turbo which is a rebranded / older garrett turbo.

The wastegate on that thing probably opens at some serious high boost since it's diesel.

Not necessarily, some of then run much lower boost than you'd expect.

AiResearch is not rebranded, it's OG Garrett, which is now currently Honeywell. Truthfully speaking if it's a a 300SL it may be an AiResearch turbo with the triangle from Allied Signal on the branding/packaging.

I've never really seen a low boost diesel, even the tdi VW's run like 18-20psi stock. I'd say to the OP, just make sure to find out when that wastegate opens if you do use it

To add what I have to this, I have a KA and its got 10k miles on the rebuild, it would be fun to put just a little t25 on it at 7psi for drifting and such. But when I Sr swap in the near future I was wondering if this would be a good buy now to save money later. But from what i am getting from you guys it would be more of an experiment? I really appreciate the feedback as well!

Just because a turbo runs 'high boost' doesn't mean anything. 18 psi on a pea shooter isn't going to do the same things 18psi on a 76mm is ya know?

Some run big amounts of boost, some run 10 psi, some run 6...but all run different turbochargers.

There are two ways to look at it.


1. (And the option I'd suggest) Start gathering parts for the SR swap and save money now. No reason to spend half-assed cash on a turbo KA, only to not end up using half of it for the SR. If that KA is rebuild and running fine, leave her be...no reason to potentially blow it up and then get zero money for it.

2. If you're going SR20, buy parts that will fit 'that build' and see if they translate to the KA. Most parts do, but this way you can use the stuff on both setups.

Wow, Thanks man that's so good advice. Ok so I like the first way you explained it as well as the second. So if I got that t3 turbo off the Mercedes it would be an experiment? SR's I know can take a good beating on high psi so I figured if I buy that turbo for $50 id save myself $400+ on a new garret one.

Nothing wrong with a "Diesel" turbo. 70% of the DSM Guys running budget setups now run Holsets seeing as 16g prices have skyrocketed. 20g prices are just not competitive with holsets either.

Remember diesel turbos are designed to spool with slower moving exhaust. Gas burners will spool even some of the intermediate to big sized truck turbos fairly quickly.

Remember, cheap doesn't always been better.


While that turbo may cost you 50 dollars, you need to consider that it

-Needs an intake setup
-Needs outlet pipe setup and fabbed
-Needs a custom downpipe setup sorted and fabbed
-Needs lines for oil and or water
-Needs to bolt up to a manifold in regard to the footprint.


So with that all considered, while the turbo may only cost 50, you may speend 500-700 to make it work....whereas you could send 350 on a turbo and have it all work as it should.
