z31 t3 on a ka24de

[Nissan_240sx]

Whats up everyone, I'm about to start on this proj. Recently got a z31 t3 and I'm wondering if there are any other people on here that uses this turbo. I saw this post zerothread?id=107709 made by crzycav86, anyone know how his setup is now? anything new etc. problems? I've got some question's I'd like to ask him or anyone using the z31 t3. Thanks

[Jookmasta]

i am also running a 60 trim .63 a/r str8 t3 turbo..............what questions do ya have?

[mirra32]

i have my z31 turbo sitting in the closet as well....any more updates on performance, motor, or problems. please let us know...i'm about to perform a rebuild myself.....so close...so close

[Jookmasta]

well motor is running fine at 15-16 psi. at this boost level, i dont think i will need much more to satisfy my need as i am a happy camper. no problems with the turbo. anything specific u want to know?

[Chezedik]

I have mine. I rebuilt it using a T04b compressor. Will be installing it in the fall.

I'm wondering if you guy's are still using the z31 turbo elbow? What are your set ups?what exhaust manifold do you use? what down pipe? how big are your hot and cold pipes? oil lines? etc.. pics of it would be nice.

Here's what I think my set up will be..

z31 t3jgs log manifold ( not sure )370 sr injectorsstock mafsafc 2ssqv bovWalbro 255lph fuel pumpoil lines ( not sure )down pipe ( not sure )exhaust ( custom )

Just looking to run stock boost for now, thats around 6-7psi? correct me if I'm wrong.How much hp am I looking at with this set up?

Thanks alot

[Jookmasta]

i am using somewhat of a variation of the turbo elbow. i am running a jgs log manifold. my dp is custom and my feed line is ss (7 ft long) and the return line is a rubber fuel hose from advance. all of my intercooler piping is 2.5" and i am running a BRM exhaust. stock boost should be about 6.5 psi.

[Nissan_240sx]

cool, where did you get your oil lines from? are you running any fuel management? do you have any pics of your set up? sorry for all the questions.. just want to make sure of things. Thanks alot

[hannibal]

You can buy the 7 bolt turbine outlet/downpipe flange from http://www.blaastperformance.com Ive heard theyre not the best company, but that flange is hard to find. A better option would be fabbing it yourself if you have the means.

EDIT: On second thought, that flange would only work with an external wastegate. Or maybe if you can fab a creative wastegate dump/downpipe.

[Jookmasta]

my oil lines were custom made by a company called paragdim performance in cali.........they specialize in ss lines and their customer service is excellent. the one line ran me 50 bux but then again it is a 7 ft. ss line. as for fuel, using deatchwerks 480cc injectors controlled by and SAFC and an enthalpy ecu....

ill see if i can some pics up but i only have top shots of the engine bay

[Chezedik]

I have their flange, and had no problem getting it. I just wish the outlet was a little bigger. I may see about getting that done. I am using cheapoillines.com lines. They are nice. I know that Kawaii was using that turbo with a modified elbow, and at least one other person. I was basically just using it as a CHRA.

[Nissan_240sx]

Thanks hope to see the pics.

So would I be able to get away with using the z31 elbow?

I'll post pics of the turbo later

Thanks guys

[crzycav86]

anyone know how his setup is now? anything new etc. problems? I've got some question's I'd like to ask him or anyone using the z31 t3. Thanks

Hi there. My setup is doing just fine. In October it made 250whp/256wtq at 11 psi or so, but the 370cc injectors were not able keep up with fueling, and so the afr was about 13.5:1 at peak torque. Since that was too lean, I installed an adjustable fpr, and then I went back to school and didn't really mess with it.

I also have a maxima maf that I will put on it sometime. After I put on the maf and retune it, I will turn up the boost to something like 15 psi and have at it.

No mechanical problems or anything really.

So would I be able to get away with using the z31 elbow?

I would highly recommend against it.. due to the issues illustrated in the thread(I think I talked about the issues there). Basically, if you want to use the elbow, there is exactly 1 possible way to make everything fit. having said that, your manifold will have to be welded 99% the same way mine is, otherwise one or more of the following will happen: Your oil return line will hit the motor mount(the line will run straight through it), the turbo elbow flange will hit the transmission, the compressor will hit the engine block, the compressor inlet will be too close to the power steering pump.

Anyway, building the manifold was tough... but I sure am proud of that ugly thing. lol

[Nissan_240sx]

wow that hard huh lol. Know where I could get a turbo elbow for the t3? Do you mind posting up your set up and where you got the parts from? Thanks alot

[crzycav86]

this is the current setup..

[crzycav86]

you'll probably just have to get the elbow from a a private owner, junkyard, or ebay.

I Strongly suggest that you just get a flange for it and make your own elbow. I promise you that it will be much easier.

[Nissan_240sx]

Thanks alot man.

Here are pics, turbo is much cleaner and elbow is off















BTW: What are those vac hoses on pic #6, never saw hoses there on turbos. Where do they connect to? and can I just T them together as 1 line?

[crzycav86]

Yeah, you will need to T the two lines together. They attach to the nipple on the wastegate.

[mirra32]

if you have any parts so far install what you can so you can get use to the parts and how they work.....so far i'm still N/A but have installed

-safc-z32 MAF-walbro fuel pump-wideband-lil misc guages

i'm about to install my 370's and see how i'm going to mount the intercooler

thats just less to worry about putting on when you go turbo...

[Chezedik]

You should think about freshening that thing up before you install it.

[Nissan_240sx]

Would spraying carb cleaner inside the compressor/turbine wheel, oil in and out be ok? I've heard good things about doing that so far. You think it's ok?

[Chezedik]

How's the play? Unless you don't have any experience rebuilding them, I would take it apart and dip it. Otherwise carb cleaner, and then flush the oil ports with clean oil.

[Nissan_240sx]

There is No shaft play what so ever =)I took off the compressor housing and sprayed it with carb cleaner and wiped it, much cleaner. How would I go about flushing the oil ports? just pour oil in?

Thanks

[Chezedik]

Yes, over a tub, run oil through the parts and turn it. You won't get much cleaner, but it may help. Maybe even a little carb cleaner or kerosene before, that way if the previous owner was less than diligent in letting the car spool down, you can clean out the bearings.

[Iamjohnhayes]

sorry for the shameless plug but....

i happen to have an internally wastegated garrett super 60 .60 / .48 if that doesn't work out for you. brand new i never used it b/c im now selling my 89 hatch

[Nissan_240sx]

No thank's I think I will stick to the t3 as my daily driver, thank's for the offer though.

Can anyone give me a link to a reliable site that sells oil lines ( oil feed and return for the z31 t3 ) the sites listed above were dead links.Please post the part numbers, I'm pretty lost when it comes to buying oil lines lol..Also how good do the oil filter sandwhich plate work? or would it be better to use the oil sending unit? Thanks alot

quick question to you guys running the z31 turbo:

what psi can you spin these to untill they run out of efficiency range and just start pumping heat?

[hannibal]

I dont think you should run more than the 15psi Jook's running. Remember he has a larger trim turbine so his setup is slightly more efficient than the Z31 T3 at higher airflow.

If you plot it on a compressor map, you can see efficiency drops below 65% around at that boost level.

[crzycav86]

quick question to you guys running the z31 turbo:

what psi can you spin these to untill they run out of efficiency range and just start pumping heat?

it's pretty efficient up to like 10-11 psi. I plan on eventually going up further to like 15 psi and then get it on the dyno to see how much it makes.

[Nissan_240sx]

I will be using the 300z elbow, will the stock 02 sensor fit?

Thanks
