From what I know they are a better turbo than an IHI.

This is off of Stinger website. Good read on his FAQ page. Lost more info about things other than turbo's as well.

What turbo should I get for "X" hp?
-Stock (87-88 Turbo Coupe) Ishi-Warner IHI: Less than 250rwhp, super quick spooling (full boost at 1800-2000 rpm with a few airflow mods) but runs out of steam at higher engine speeds. Great for heavy cars or daily drivers. Good to 18psi or so.
-Stock (83-86 Mustang/Turbo Coupe, 84-89 Merkur) Garrett/AiResearch T3: Up to about 300rwhp. Full boost at 2500 rpm or so with a few airflow mods, pulls pretty well up top. Has a very hard "kick" when boost kicks in. Great for a daily driver/street terror with minor mods. Good to 23psi or so.
-T3/T4 Hybrid T04E 46 trim compressor/Stage III exhaust side with .48 a/r for street cars, .63 a/r for street/strip. Great for engines in the 250-350rwhp range. Full boost at 3100rpm or so with a header and supporting mods. Nice linear power throughout rpm range. Great for street/strip cars in the 12-13 second 1/4 mile range. Good to 25psi or so.
-T3/T4 Hybrid T04E 50 trim compressor/Stage III exhaust side with .48 a/r for street cars, .63 a/r for street/strip: Great for engines in the 300-430rwhp range. Full boost at 3300rpm or so with a header and supporting mods. Nice linear power throughout rpm range. Great for street/strip cars in the 11-12 second 1/4 mile range. Good to 35psi or so.
-Holset HY35: Great for engines in the 300-480+rwhp range. Full boost at 3600rpm or so with a header and supporting mods. Pulls like a freight train in the higher rpm range. Great for street/strip cars in the 10-12 second 1/4 mile range. Loves 30+psi of boost.
-Holset HE351: Slightly upgraded version of HY35. Great for engines in the 300-480+rwhp range. Full boost at 3600rpm or so with a header and supporting mods. Pulls like a freight train in the higher rpm range. Great for street/strip cars in the 10-12 second 1/4 mile range. Loves 30+psi of boost.
-Holset HX35: Great for engines in the 380-500rwhp range. Full boost at 3800rpm or so with a header and supporting mods. Pulls like a freight train in the higher rpm range. Great for street/strip cars in the 10-11 second 1/4 mile range. Loves 30+psi of boost. Split scroll exhaust housing causes boost control problems unless an external wastegate is used or the divider is cut out.
-T61: Great for engines in the 400-600rwhp range. Full boost at 4000rpm or so with a header and supporting mods. Great for serious street cars or drag cars in the 9-10 second 1/4 mile range. Can handle upwards of 40psi.
-There are also many new GT series turbos that will work on 2.3T applications. I did not include them because they are a much more expensive turbo and since they have many more options available, they should be spec'd out specifically for your setup.

Yeah I have the FAQ bookmarked and I look at it daily it seems.
I am not sure I understand the term "trim" is my turbo the 50 trim or I thought it was 57 trim.

So stinger seems to think my turbo is good up to 35psi?

Couldn't say unless you can positively ID which turbo it is. Sorry I'm not much help with that part!

Im starting to think perhaps it really is just an ebay turbo... maybe I will sell it to a honda guy for what I paid and find a real turbo.

Trim has to do with the ratio between the impeller diameter and the intake hole size. Example: a 50 trim would have a 3 in hole and a 6 in wheel.

So I am starting to get too far ahead of myself buying and researching new parts and I am slacking on the small details. Ive got an oil and a coolant leak, power steering pump needs to be replaced and I still havent hidden the wiring in the fenders. Im going to stop buying stuff and get this car to 100% as it is, also need to do some body work before I paint it. Ugh... the slow boring stuff now.

Nice lil build, keep it up. I highly recommend lining everything out real good before going to town modding things especially if using stock ECU and sensors they can be very finicky. I also may have some things you may be interested that came off my old setup. hy35 turbo, stinger manifold, tial 38mm WG, 3in stinger downpipe...

Need anything just PM, I know these 2.3T's pretty well.
