Garret T3 60-1 the Right Turbo for My Goals?
Hello all. I'm in the home stretch of piecing together my build and purchasing the big ticket items. This past weekend I picked up a turbo on the loose recommendation of my tuner. I'm not an expert on reading compressor maps or anything, and was hoping some of you could provide your take on this setup.
Turbo:
-Garrett T3 60-1
-T04S compressor housing .70 A/R
-60 Trim wheel
-T3 turbine housing .63 A/R
-76 Trim Stage 3 wheel
Engine:
-F23 Single Cam
-10.1:1cr
I haven't yet chosen a cam. N/A the engine made peak power at 6000rpm, so I'll be looking for a cam to raise peak power to 6500-7000. My goal is to reach 400whp on pump gas. I don't want peaky spooling. Since the power band for the engine is wide and flat but moderately low, I would like the turbo to spool quickly, but without having to drive around in part-throttle boost. I chose the .63 turbine over .82 a/r, and I'd like to know whether that was the best choice for this setup. Any help?

I put in your specs @ sea level and this turbo is not the one you need.. your way in the surge point and not only that, the 60-1 has a small efficiency zone.
Maybe the Shodan can come and chime in.. cuz all the one on the maps ive seen isnt the best.. the only one that comes close is this one. and even this one isnt that great..
manifold configuration, exhaust sizing, intercooler and a few other factors will need to be listed to narrow it down.

Thanks Esoteric. Can you dumb that down for me a little? I understand compressor surge occurs when the compressor's output exceeds the engine's ability to consume air, starting a perpetual effect where the compressor wheel stalls then bursts back to speed rapidly. Does this mean the turbo is too large for this application? Would the larger .82A/R turbine wheel improve things?

Em, I was told by a couple people that the precision billets will make awesome power and have to be warrantied 1-2 times before it goes out of warranty and finishes falling apart. It was a bit sarcastic, but not stated out of ignorance.

If you want a turbo that spoils nice the 60-1 is def not what your looking for. I would look at one of the gt30's or check out the silver surfer. Silver surfer probally having the beat response. Hell even one of the t3/t04e 57 or 60 grins have better response then the 60-1. Everything I mentioned is capable of 400whp.

It will be a bit laggy, even with a "cam", but it could still be doable. I just would be happy with something a little smaller and a bit more responsive.

Hmmm.. 400whp on pump gas, with a Big displacement single cam and full pressure using a 60-1. Its not the worst choice to have made, but I'm a little concerned about the upper rpm band when (and if) going for over 450whp, in which you'll use a different octane fuel with differing properties..

I understand it's not a BB turbo and spool won't be instant, but it's not a 1.8l either (the car made over 175ft/lb at the wheels in N/A form). Is the 60-1 really that big that it's going cause issues or be unpleasant like I'm hearing? Most F series guys (single cam VTEC) use T3/T4 57 trims on stock bottom ends but rarely make beyond 260whp. What would be your recommendation for a sub-$1000 turbo (and perhaps a sub-$1300) turbo with the juice to comfortably make 400 on this motor?

Re: Garret T3 60-1 the Right Turbo for My Goals?
It's just unpleasant because the package (exhaust wheel, housing, compressor wheel and compressor housing) is rather a bad mismatch.
The reason those guys go only 260whp is because they aren't using an aftermarket piston and rod combination like you are using. On something like a GT3257, surfer, or even 60 trim (all under $1000), A Precision 5858 or 5252 (also under $1000), and you can push to 400whp, but you might have to put a bit better fuel to do 400whp on 93 octane gas. Just be prepared to give it some pressure. your tuner will determine how much. nothing can be predetermined beforehand, so don't ask.

Re: Garret T3 60-1 the Right Turbo for My Goals?
Ok, so I'm reading over some threads here stating that the 60-1 stage 3 turbine wheel is not a good combination with its compressor wheel and large housing, but that it's much more suitable with the stage 5 turbine wheel option? Would a T3/T4 60 trim with .63 ar hot side and stage 3 compressor wheel be a much better alternative for my needs? If so, what would be its BB counterpart?

Re: Garret T3 60-1 the Right Turbo for My Goals?
Thanks for the link and the info guys. I've sent an e-mail to Greg at Go-Autoworks where I ordered the 60-1 and asked for a quote to change my order. Of course he doesn't carry the silver surfer, but there are a few other options there.
Since I have no intention of surpassing 400whp, I asked him about the Garrett t3/t4 60 trim, but he recommended the 50 trim saying it would be efficient to 400, and be particularly responsive, similar to what you guys have said about the surfer.
Your thoughts?

Don't think the 50 trim will get you to 400whp. Someone correct me if I'm wrong but I'm pretty sure there 350ish max. Don't get me wrong would be a fun Lil turbo.

I was a bit skeptical when he said that too, but I did find this on Full-race's site, pretty much confirming what Greg said.

The full-race site says 420WHP. ATP here says 450 at the crank. That's almost in line with one another. Go-Autoworks also states 450, and he lists his numbers at the crank as well.

Would the 57 trim be a good compromise then?

The 60-1 wouldn't be on my list. If this were my setup, I'd be looking at the GT32 or Precision 58mm. If either of these are out of your price range, look into the T3/T4 60 trim.

except that their aren't any compressor maps for precision turbos and precision never intends to produce any... their excuse was the cost to do so and the fact (they say) that the backplate and housing combos invalidate the maps..
i'll never buy a turbo that I can't map out first... Plus I've heard that almost every journal bearing precision turbo has to be repaired/replaced due to bearing failure
