Need Turbocharger Advice
A turbo setup has its appeal. I want to do the twin SC setup, but it's looking like I will turbo charge it instead. I'm sure everyone here already knows turbos are better anyway.
So, I need to know what turbo I should use. I know, that's a newb question right. I know a little about turbos and I'm doing my best to learn. I've read the turbo specific sections of Maximum Boost, though I certainly need to reread it. (I've already read Supercharged cover to cover)
I want to make big power. 300 whp minimum, but would like to make more as I think the stock motor will take it. I will build a nice custom manifold, 3" exhaust, etc. I have a lot of head work. I'm not really worried about spool or "lag" as I will have nitrous to spool the turbo.
I've looked at the eBay turbo's per Markp's suggestion. The Chinacharger t3/t4 "with the blue tag" is no longer on there unfortunately. Besides, I think I would rather pay up front for a name brand turbo for peace of mind as this is my college car/daily driver.
Others have suggested avoiding the eBay turbos and getting a name brand one. That sounds fine to me. I'll have the money this summer to buy a good one, be it new or used. I'm considering the following turbos offered by TunerToys:
Garrett T3 60-1 with .63AR (715583-5006) - $615 Shipped
Garrett T3 60-1 with .82AR (715583-5007) - $615.00 Shipped
Garrett T3/T4E 60trim, 63ar - $583 shipped
The only difference between the first two is the A/R of the turbine. The third is a Garret t3/t4. Which turbo would be the best choice for say 300whp? 350whp? It's my understanding the larger A/R of the turbine, the more lag, but more HP. That's a trade off I'm willing to make.
Thanks.

I think you haven't had much response because you're asking for a couple things that are mutually exclusive. If you're "only" looking for ~325 whp, then you don't need a turbo that spools at 5k rpm. Something T3 with a 63A/R turbine is in your future, just pick your compressor to suit. A 50 trim maybe. Which is what I'm leaning towards myself.

For clarity, I'm NOT 'only' looking for 300whp. I would like to buy a turbo that will take me to 400whp up front, and build to it. I plan to go straight to 300whp. I'll only be at the 250whp range long enough to tune those cells and make sure everything is safe. Then I turn up the boost and tune again. Then get the WI going and make sure everything is ready, then push it further.

This looks promising: http://cgi.ebay.com/ebaymotors/GENUI...QQcmdZViewItem
Only question is I don't see the word Garret on the compressor housing.

Includes a Garrett TA34 stage 2 turbine wheel and Turbonetics .63 a/r turbine housing with the standard Ford 5 bolt T3 exhaust outlet flange.
then it's not really a genuine Garrett now is it?!

IMO you are better off buying a new garrett turbo from garrett retailer for $150 more. That'll remove the majority of risk associated with the eBay turbos. I just did a bunch of shopping around and TunerToys had very competitive pricing. If you do have a problem after the purchase you have somebody to go to.

Ok, so we have the t3/t4 setup. Likely a .63 A/R turbine. I see "50 trim" used a few times. There is a 57 and 60 trim listed on TT's site. I suppose he can order the 50 though I need to verify that. Would I be better off with a 57 or 60 trim? What effects would a larger compressor have if I keep the same .63 A/R turbine?

FWIW, if you wanted to go chinacharger which iirc is a copy of the 57 trim, they do still have those blue tag units on ebay, but just not the same seller that markp got it from. A larger compressor trim/wheel will create later spool, but if you meet your goals with the "smaller" turbo without straining it (aka out of efficiency range/creating excessive heat) and at earlier rpm, why go larger if not necessary?
Also, not sure about budget/footprint constraints but you might want to also take a look at the GT3071/3076.

Yea, for clarity I already have the headwork and nitrous on the car, that's why I figure I could run a large one and be ok. I don't want to go larger than necessary. I know little about these things so I'm asking. If a 50 trim will take me to 400whp, great, that will work. Sounds like your saying it took eliminator to 500 with just a turbine swap. In that case, I would infer that a 57 or 60 trim would be overkill.

FWIW, a lot of honda guys love the 57 trim for their 1.8L, BUT their heads also flow waaaaaaay better than ours. I just said 50 trim as there is actual dyno info for a miata.
