Sorry for caps I also need a rebuild kit for this where should I find one?

 

Autoworks should be able to identify that snail for ya pretty easily.

 

you will make more power....by not using that log manifold.

 

I would get a another manifold but no money cuz corona

 

Seems a bit big IMHO But depends what your goals are. Can't say whether anyone should use any turbo without goals usually, unless it's grosely oversized or undersized.

I would guess that turbo would be good for about 450-500HP max and start to spool around 4-4.5k+ on most B series.

But I'm just pulling those numbers out of my *** based off what you provided. 57/0.63 is what a lot of common ebay/honda turbos are sized at.

If you're going for 350+whp then it's probably fine. If you want quick spool and 300whp or less than it might be a bit large.

Remember it's not just about peak power but also area under the curve. A car that has a higher "average" horsepower can beat a car that has higher "peak" horsepower.

IMHO asking how much HP someone makes and getting a peak number is about as useful as asking how many PSI someone is running without knowing their engine/turbo; it might give you a ballpark idea but it's not the whole story.

 

Actually yeah 450-500 is my goal haha at this point idk where to buy the correct rebuild kit for this one. I bought it and it was advertise as a gt30.

 

In old school Turbonetics terms you have whats called a T66, this version has the slightly newer HP66 wheel and F1-series turbine wheel. They were more often than not T4-based turbos so the version you have with the 66mm inducer paired with the F1 57mm turbine wheel is a strange combination. This was the predecessor to the Turbonetics GT-K from what I remember.

The compressor wheel is way more than you need for 450 - 500whp. That compressor wheel is capable of 60+ lb/min (600hp) and was usually paired with the Stage 5/F1-62 or P-trim/F1-64 turbine wheels . The turbo is a bit of mismatch for your application to be honest.

The turbine side is sized nicely for your goals and engine - perhaps consider having it "downgraded" to a wheel that offers ~55 lb/min flow rate.

 

^^^ Good catch on both, extremeracer.

This turbo looks like it was made around the time that they started using the HPC F1 series turbine wheels (PTE also used these in the 1st half of the decate).

You're not going to find a "rebuild kit" for this, as the turbine wheel/shaft, which uses a different bearing size kit than your typical "T3/T4". So, your best bet is to either send it to Turbonetics for inspection (or even see for a bit of money if you can get the correct sized compressor wheel for it) or hopefully find a place that will rebuild/refit Turbonetics parts.. (which may cost more than the turbocharger is worth). But I would only do this if you have reason to believe something is wrong, as most places will not take apart a turbocharger just to "inspect" it. If they take it apart, they'll want money to replace everything, if possible, and then send it back. That's easily $400.. If you think nothing is wrong, just run it.

 

I thought the compressor looked a little big..!

 

Well then, I guess I'll have to shoot for 600 lol.
