View Full Version : 240sx Merkur Custom Turbo
I have been planning my custom turbo setup and now im ready to purchase the turbo.... I was going to buy a merkur turbo, but then my friend(with a merkur) said that it wouldnt work, well it would but it would be dumb becuz the turbo would be upside down(since the merkurs engine is reverse of ours) have any of you seen this setup and do you know if it would work also would anyone recomend a 300zx turbo over a merkur, or any other stock turbo i can pick up c heap. Thanks alot.

you couldn't rotate the center section so the turbo would work "upside down"??

Yeah, I'm pretty sure you can rotate the compressor housing.

I know the housing can be rotated.. but the other fact remains.. the wastegate would be on the top.. I dont know if its a big deal.. just didnt know how it would affect flow.. unless we had a header made to come around the exhuast housing and bolt up like a turbo on the passanger side..
The turbo is a t3 .60/.63, with a four bolt flange.. oil cooled.. dont know if that matters... I asked on 240sxforums, what type of injectors you'll use and no one seemed to understand.. so Ill try here... What type of injectors do 240's use?? TurboFords use low impedence 35lb - 350cc???? dont know cc's.. I also know where you can get 46lb low impedence and adjustable fuel pressure reg's in the junkyards.. dont know how much of these all converts over..

Not all injectors are created equally. Most injectors won't convert to the nissan rail. They can be used with a custom rail though.
35lbs = 367.5cc just multiply pounds by 10.5 and vice versa.
Low impedance aren't necessarily sought after, because we use saturated (high impedance) injectors and low impedance will require resistors. Stock size is 270cc.
If I missed something... just ask.

Thanks, that was what I was after.. just didnt want to get him a set of these injectors and the car never run right and then melt a piston.. cause then it would have been better to buy the right injectors for a little bit more ... thanks

No... it wouldn't be a big deal. Gravity has little to no affect on exhaust gas flow.
unless we had a header made to come around the exhuast housing and bolt up like a turbo on the passanger side..
That would be a big deal though :p too complicated for no reason.
Can you hink of anything else i should lookfor when picking out a turbo, like a non movable shaft. Thanks for postin.

Make sure it spins freely. Also check to see if any of the impeller or turbine blades are bent at all. Also, if the car has been in the junk yard for too long, I'd be skeptical. You could probably buy it and take it to someone to have it rebuilt. Turbos are rather simple. I took one apart and put it back together and it was the size of your head. :D Not very many parts at all.

The only problem with taking it apart is you risk putting it back together off balance. I suppose if you mark the wheels to the housings you could do it.... but turbos are supposed to be balanced to very tight tolerances.
I'm sure you could get away with it, but why bother when you could just get a turbo in better condition for a little more?? A junkyard generally won't sell you a blown turbo for more than the $300 cost of a rebuild less than a good turbo.
Also, if you look around you can find some pretty good deals. When I blew my TD05 I was able to find one in good condition for $80. It's just a matter of looking around.
are you sayin i shouldnt buy a junkyard turbo?

No, i'm saying look for a good turbo in a junkyard rather than just picking up a turbo because it's cheaper. Always check for shaft play and housing cracks when getting a turbo in any used condition, though.

I got my t3 in the junkyard for 50 bucks of off a Saab 900. It needed to be rebuilt so I rebuilt it for $60. the steps to rebuild a t3 are VERY easy.... except the snap rings. Balncing the turbo isnt that hard just make sure you dont bend the shaft. Any turbo you find in the junk yard however should be rebuilt. My turbo wasnt really that bad, the shaft spun well and everything, then I took it apart. I should have taken pictures of the oil that was burnt in it. I got it all out, polished everything, and it works great.
If you have questions, like everyone else said, feel free to ask.

Is there something special about that particular turbine?:confused:

I know where 5 of them are untouched, basicly its a car with tons of goodies that no one even takes a second look at.. and thinks.. that thing has a t3??? so its a sure go.. I cant find a saab to save my life, I cant find a complete volvo engine bay anywhere.. but the merkurs are complete cars minus the accidents they have been in..

plus if it's got .60/.63 housings then it should work nicely with a KA. How much are you getting the turbo for? any idea what kind of outlet the turbine has?
under $100 if i pay
no nothing special about the merkur i just like the turbo

interesting... i've been searching for a replacement T3 turbo for my car. Looking for one with a 3 bolt exhaust flange that will just drop into my setup without needing further modification. I'll have to look into those. My bet is that they're setup like the T-bird turbos though.

Hey ace, if its setup like the t bird turbos, just ge the flange of off a T bird and it should work fine. Thats how mines set up, with the 5 nut pattern, but the original did bolt up to a 3 nut after the wastegate. I have an external wastegate so I made a new flange.

If you are looking for 3 bolt flange dont bother with the merkur.. they are a 4 bolt rectangle.. you should look into the even scarcer Buick Grand National's.. they are the only car I know that has a 3 bolt.. or dodge cummins deisle's.. they might be a little bit.. a well built 2.3 spooled it to 15psi at 4500rpm.. I would bet money it is a 3 bolt but not sure.. dont hold it against me..

Heh... never saw a turbo with a 4 bolt rectangle turbine outlet. Square patterns, yes, but never rectangle.
I'm pretty sure you're talking about the inlet.

I'm not understanding babble. How can a Cummins Turbo Diesel be "a little bit" 3 bolt?
How does a 2.3L spool up a turbo at 4500 when it's made for a 5.9L 360ci straight-6 diesel truck.

maybe the turbo spools at 2000 on the 5.9L diesel?

The deisle trucks redline at like 4 grand.. and they spool almost constantly.. and I can send you the link of the holset on many of turbofords if you would like.. I am not just talking out of my ass.. hx35.. or hy35.. I can look into all of this closer if anyone is interested.. but if you are just goin to sit there and say its not possible I wont worry about it.. fun stuff
