I was offered a new T3 turbo for an 86 300ZX for $125. It is just the turbo itself. I plan on doing the SR next spring, but I was just wondering if you guys think I should buy it and just put together a cheap turbo kit until then, or is it a waste of time?

its a good sized turbo, I don't know the exact specs of it.....

Depending on what SR you buy that should make more power then the stock t-25 on a s13 sr20.


if you put it on a KA24 you wouldn't need to so a SR swap.....

Really? I am doing the S14 blacktop, but maybe I will look more into buying the turbo.

Which do you want more? KA-T or SR?

No point in wasting money on that turbo if you are just gonna swap an SR in later. So make up your mind one way or the other.

Yea you have a good point.

Id got find another KA-T to drive to make up your mind... but if you do decide to go KA-T dont do a ghetto kit.


GSR2N You want the SR... and you want wicked 18x10 -8 wheels... and porn

So do you guys have any idea how much power I would make with a T3 turbo setup. I am not talking cheap ass stuff, but also not expensive ass stuff either. I am talking about using a top mount manifold and downpipe from ebay and stuff, but not no backyard PVC pipe put together.

Fine line between ghetto and resourceful.

IDK the specs ont he turbo. Guestimation of about 300whp. Maybe a lil more.

ok, thats cool. I am looking to make no more than 250 to 300hp right now, so a T3 should be plenty big enough right. As of now I am looking into this one:

What do you think?

If he was smart, he woul dhave put a picture of the tag on the turbo.

For what? which tag?
I am also looking at this one:

Let me know if you think any might be a good buy, because if they are, then I might go ahead.

Looks like a pretty good deal. Prolly do what you want easily.

that first one has the cheap spray paint job on it, i wouldnt buy it...the second one doesnt look all that bad

Just in case, I was talking about the second. Haven't even looked at the first.

On that second one then, how would I find a turbo pipe to hook up to it in order for it to connect with a downpipe because it has a 5 bolt on it and I don't know where I would get one like that.

should be able to find pretty much anything you need in here (http://www.atpturbo.com/Merchant2/merchant.mvc?Screen=CTGY&Store_Code=tp&Category_Code=FLS)

You're thinking of the SSautochrome manifold. From what I've heard, its hit or miss on quality. But a guy on ka-t.org ran a 12.xx on it so I guess thats a hit.lol

atp has all the intercooler piping you need along with couplers adn T-bolt clamps, vacuum hoses, wastegates, bov, turbos, pretty much everything you'll need. Trust me, taking care of stuff correctly the first time pays off. I probably spent enough on cheap couplers to have bought three nice setups.

don't use a VQ turbo on the SR20... the T25 flange although on both is the same, a 3.0 L VQ T25 flange is ment to run with 1.5 L of flow, the T25 flange on a Sr T25 turbo, is ment to run with 2.0 L of flow?

SO, using a skyline turbo on a sr20, you will chock the turbo at top end. why? skyline tt hase a flow rate of 1.3 L Sr 2.0 L ?

don't get it, used turbos are a baaaad idea. rebuild them and they cost almost as much as the new ones.

oh Z31 Turbo... i thought ur using the Z32...

Read the first post. It says 86 300ZX, which means Z31, not Z32.

ATP turbo looks like a good place, but they don't seem to have the 5 bolt flange for the compressor side of a turbo like this one:

Does any one know where I might pic up such a flange??

Now that I think about it, is it normal to have those 5 bolt holes on that side of the compressor? I thought normally they were different and looked like this one:

I'd rather have one with a coupler style comrpessor inlet. Makes for easier fitting. But I'm pretty sure you can buy adapters for the bolt style flanges.

Uh, how you gonna run with without a MAFS there? Remeber to put it at least 12" away fromt eh compressor inlet.

nissanfanatic, and other who know about turbos, why are the maf mounted before the turbo and the piping? Wouldn't it be more percise if mounted right before the intake manifold? Then if you have a leak or running atmospheric bov you won't stall the engine, instead start running it like NA tuned for turbo (if that makes sense).
And I would go for the second turbo or aftermarket hybrid, the first turbo looks way to funny, like they are trying to cover something.

IIRC, it's possible to moun it after the turbo, but because of pressure in the system, you might damage the MAFS, it's made to measure air gently flowing into the intake, not a 10psi hurricane.

Maybe, I never though of all the pressure on the unit, but then again the air is sucked in pretty fast too.

Adn the heat. Plus some MAFS's don't hold pressure well. Its just better to mount it before the turbo IMO.

Technical names are:

Blow through-mafs is mounted after the turbo
Draw through-MAFS is mounted before the turbo.

Old School SR guys hit on that so they didnt set stuff on fire when the IC piping came off but then you have to deal with tuning the ECU to recognize the new position so it would probably be easier to just go straigt to a MAP setup


Dayumm Homeboy that ATP site was a good find.
