a friend of mine has a 2006 ion redline and ever since i told him about my upcoming build in march he's been wanting to buy my stock turbo kit (turbo manifold, intercooler, etc..) for 850 bucks. i told him i dont think they'll bolt up for use. i think its possibly a costly swap. but i could be wrong cuz i dont know much about the lsj's and if any lnf parts will work for it. anyone have any input? will this work? also, i tried the search and never found a definite answer. thanks.

 

Been curious about this. Would make for a cheap turbo build to 275ish

 

honestly i think it would get more. i mean for us lnf guys we've been hitting on average 300-340. so i dont think that would be too hard for the lsj guys with bigger injectors and possibly cams. (assuming everything bolts up and works lol)

 

That's true. But just a basic, simple build would be 275 at least.

 

o sry. misunderstood you lol. yeah for sure that would easily get that without even pushing it. my friend is like praying it works cuz he wants it so bad lol.

 

Yes, the Turbo Mani, Turbo, and O2 Housing will 100% work on an LSJ. As will the charge piping and intake. The only thing you really can't swap between the two is the Intake Manifold.

 

So if he remOved the supercharger and put on the parts from my car( with custom intake manifold, charge pipes, down pipe intercooler, etc) everything will work? Has anyone done this before with any success?

 

Its been done on a cavalier to two and since the l61 and lsj are externally identical it should work. I dont see this making much more than 275 though. Thats a tiny ass turbo and you dont have the benefits of VVT and DI.

 

wrong

a couple of people have done this with results better then an lnf

 

Better results than the LNF you say? Only reason I could think to explain that is the intake ports on the lnf. I mean for that turbo an LNF making 340 wheel is on the verge of magic.

 

the lsj isent limited in the same areas as the lnf the only thing they realy got better was a block and the average lnf makes low 300s and a lnf making mid to high 300s id say it was magical or a happy dyno

LSJ also has slightly higher compression. Adds to our ability to make more power on the same boost level.

He doesn't need a custom Intake Manifold, he can use the Saab LK9 manifold. But yes, everything other than that will work. He'll need a custom Cold Side charge pipe though, as the LK9 manifold is a top feeder, opposed to the bottom feeder LNF.



He's going to need a great tuner though, with a lot of time. That turbo spools hellaciously fast on an LSJ. The guy i know that did it was having trouble with compressor surge because when he mashed the gas, the turbo would be fully spooled before the TB even opened all the way.

 

He doesnt even need the saab mani, he can use a normal L61/LE5 plastic one. Though if you go to really push the boost it may split but last I checked someone was running one with 25pis irrc with no problems, though dont quote me on that one.

 

That's true. It'd probably perform a little bit better too, since it wouldn't heat soak nearly as much... but I personally would just use a phenolic spacer and not risk it splitting.

 

I mentioned it because its easier and cheaper to find, and the op made it sound like his friend wanted to go a bit cheap (though if he did he'd have offered 350 for the LNF turbo setup, because thats what he could get the whole saab setup for from the junk yard.)

 

350 is a little cheap for all the lnf turbo components dont you think? there's people on the forum selling just the turbo for that price. but yeah im not going to sell it for 850 anyway probably around 600-750 for everything.

who would be a good tuner for this kind of project?

thanks again for all the input everyone. i greatly appreciate it

 

On E-85 mine shud put somewhere around 330ish to the wheels, OP that's a can of worms on who would be a good tuner, shops will be expensive, and I don't know of anyone good with hpt in your area unless your willing travel, vince is vastly knowledgable and has prolly done a similar set-up if not one of the same.

 

If anything vince can @ least get you a gd baseline tune and after that u can explore with further options, he'll put ya on the right path

 

 

So you could just pull everything off say a Saab 9-3 and ti will fit the LSJ? Thats interesting. I didnt know that.

 

The LSJ is an LK9 longblock with the supercharger set-up, instead of the turbo set-up. VERY old information.

All Ecotecs share the same Intake and Exhaust flange patterns and therefore parts are interchangeable... with the exception of the LNF's Intake, as the DI system forced things to be changed.

 

You will need to replace the LSJ coolant cross over pipe with one from the LNF to make clearance for the turbo/manifold.









A cheap solution for the Intake manifold would be to use the stock M62 and LSJ IM as an intake. Remove the bypass valve from the M62 and it will never make boost. The rotors will spin freely and you don't have to worry about re-routing the serpentine belt or changing to a 2.2 alternator.

I am pretty sure the stock LNF charged air pipe would work to run from the outlet of the turbo to the TB. It would need to be cut off right at the TB and connected with a 90* silicone elbow. Then the MAf sensor would have to be relocated to intake. An aftermarket LNF intake should work in the RL although the Hahn makes an good option because it can be directed into the fender well to get the coolest air possible.

Another good option for the RL would be to point the outlet of the turbo down and run the charged air pipe up under the engine. Keep the top of stock intake with the maf holder and connect the charged air pipe to Maf holder. That would give you a blow through setup.

I have some of these parts if anyone is interested.
