13B-RE street ported w/ TO4E?
I'm just wondering, what would be a suffecient trim size, compressor A/R and hotside A/R TO4E on a street ported 13B-RE running 14 - 15psi on pump gas? Or is this turbo too small for this application? I was thinking, small compressor and big hotside(1.00a/r) for fast spooling and good top end?...or am I totally off here?
any thoughts?

Depends on how much hp you're looking to make... Based on the compressor map off the Turbonetics site, the T04E 60trim should be good for around 350hp depending on your motor. I've heard the 13b-re exhaust sleeves are very restrictive, so if you've swapped them out already, then a 1.00 turbine A/R (divided) or a .96 (collected) should work fairly well for fast spool and good top end...
Like what Infini IV says, it depends on what your after.
A T04E 60 trim with a .6 A/R T04E cover and 1.00 divided turbine (P-Trim) matched with a divided manifold is a GREAT street setup. Boost response is fast and linear and is so good you can autocross it on tight corses unlike most single conversions. Expect positive manifold pressure between 2300 and 3400 ( I know its a wide range, but theres a LOT of factors, like ports, manifold design, exhaust, tuning etc) and expect it to be at full tilt rockening at 2800~3800. You'll be limited to 350~410 wrhp @ around 14~17 psi. which is at the compressors ragged edge of effiency on a street ported 13b.

I am still very partial to a TO4E with a 60-1 compressor wheel which is 70mm i believe.
I would do a .70 compressor and a 1.15 A/R turbine housing.
They are commonly refered to as a TO4S
They can do ~400RWHP @ 15-17psi usually and spool ~3500rpms.

*BTW, this engine will be in a FC, and I figure a 13B-RE will be better in the long run vs the 13BT. And I can get one at a good price, rebuild and ported.
Well I want to start easy, nothing crazy. TO4E's are inexpensive, and very responsive turbos, and like you mentioned, great for the street and that is exactly what I had in mind. Engine wise, street ported (duh), ported tb, light weight pullies, etc. The only challenge is tuning, since I have no experiance in tuning I can't do it myself and around here, I don't know of any tuner who can properly tune rotaries without popping the engine.
What about top end? When does a TO4E run out of "puff" 7000-7500rpm?

The 60-1 has a 2.324" inducer and 3.000" exducer which eqates to 59.030 mm and 76.2 mm.
Normally the 60-1 wheel is used in a T04S compressor housing it was designed for. It has a .7 A/R with a 4" inlet and 2.5" disscharge. Its normally referred to a "T04S" because it normally comes with a T04S housing. If you were to use a T04E comp housing you'd be using a .6 A/R and a 3" inlet and 2" ~2.25" disscharge. You be limiting flow slightly with the T04E housing, although your boost response would most likely be a bit more linear.
I like the 60-1 more so as the best streetable "cheap" turbo. It flows more then the T04E with very slight spool penalty. If your after 400 wrhp and great spool this is your turbo unless you have the money for the newer ball bearing turbos now offered. Specs should go as such:
T04S comp housing .7 A/R
60-1 wheel
P-trim turbine
.84, 1.00, 1.15 A/R if going divided (I recommend 1.00 A/R)
Or if your on a budget and get a log collected style manifold go with the .96 A/R . ALL HOUSINGS TANG. Going collected will have a slower spool AND less top end.
The T04E tends to hold boost (1 bar, or about 14~15 psi) till 8K on stock,mild to mid street ported 13b's. Near red line you'll be close to the compressors edge of the effient map islands. On large streeet ports and half/full bridge ports the T04E tends to run out of puff around 6500~7K.

I'm located in Ontario, near Toronto. I know of A-Spec, but they don't do any actual tuning. Atleast I don't think. Theres also Magnus Motorsports, they have that 10sec FD, but I have no clue who tuned that car. So there might some rotary tuners around here, but I don't know of any.
Who did you have in mind eVilRotor?
