I have a turbine jacket on my turbine housing and I can't see how many bolts it uses to bolt up to the downpipe.... anyone?

its 4...

That's what I thought... some one was telling me otherwise! Damn it!! I should know I'm always right!!!

The current turbine housing uses a T3 inlet flange, .77 A/R Kolkelen housing, Stage V turbine wheel, tangential 4 bolt discharge.

Do you think a T4 exhaust housing will fit in the 350Z? Will it squeeze in below the intake pipe? Do you think this will cure the backpressure issue?

It might but that Stage V turbine wheel although its oversized for what it is is a T3 turbine. A T4 housing won't work with that. As far as whether a T4 turbine will solve backpressure issues that remains to be seen using the current T4 turbines available. I don't know if a T4 turbine housing it self will fit in the current setup. I suspect it would though.

So I would have to upgrade to a T4 housing and turbine. Am I correct that this would be the next logical step here if it would fit?

you can't bolt a t4 turbo on a t3 flange either, your uppipe will have to have the t3 flange removed and a t4 welded on.

If you upgrade, and you just want 450-500, upgrade to a true 60-1 or a 62-1.

those turbos both utilize T4 turbines and housings in their 'natural' form.

Yes and as Mike said you would need to change the inlet flange for a T4 flange to do that. Although theres no such thing as a "true" 60-1 or 62-1 so to speak as you can get them with a variety of turbines attached. A 62-1 / T4 P trim would be a logical choice.

If I were to go with a 60-1 which turbine would I go with? Wouldn't I spool up later with the 62:1?

a 62-1 is a larger turbo, so yes the spool would be later.

60-1 .68 a/r P Trim or 62-1 .68 a/r P trim....I'd lean towards the 62-1.

cams (even S2's) will spool it quicker. running the 62-1 will require less boost to make the same power

The 62-1 will not spool noticeably later then a 60-1 given the same turbine. I would look at running something larger then a .63 A/R even on a T4 turbine.

I was just using the turbo matrix

JETPILOT

Could my 60:1 easilly be converted into a 60:1 T4 P Trim? Do you think I could order another up pipe with a T4 flange welded on it?

it needs a new turbine wheel.

Is this modification cost prohibitive to just replacing the turbo. I have no idea what Turbonetics would charge me for this. The new BorgWarner units are sweet!!! The GT-K being released in January for $2300 is not an option when I could get a BorgWarner for $1200 now.

Keeping in mind that the price you listed is MSRP and not what dealers will sell them for I'd like to see which Borg Warner unit you are looking at for that price. I don't know what Turbonetics would charge to change the wheel over to a T4 and use a T4 turbine housing that would fit.

I was quoted $1200 for the S258. Here is a link to the S200 BorgWarner units....

I'd like to see a compressor map for that turbo. The power numbers look to be the same as a 60-1 compressor. What size turbine does that come with? What trim...
