Im not as familiar with Turblowns manifolds as some others, but then I usually just build my own. I will say that I have had some name brand manifolds (wont say whose) through with warped flanges, so on a street car I would use the HKS cast manifold and be done with it.
Also for a street car I tend to favor the GT3582R. Easily makes the power you want at this altitude at low boost levels and is very nice on a daily driver. The last two I have installed we have used the T3 housing with an adaptor, which sounds weird but worked perfectly.
For WG's I have been using the Precision, HKS, Turbonetics, and Turbosmart gates. The Tials should be fine, just not my preference.
I personally do not care for V-mounts, but thats just me. Again typically on street cars we build an uprated SMIC setup that has proven to work just fine for up to 400whp or so for autocross and trackday work thrown in. I do believe that at our altitude it does not hurt anything to add a WMI setup and can be of great benefit. Also, we have had cars in with both the Greddy and HKS FMIC setups, and they both work OK, my issues with them are they are heavy at the wrong end of the car and if not installed properly can creat cooling issues. I will warn you that an improperly installed V-mount will cause many more issues than they ever hope to cure, and can be a real PITA to get right.
So my FC hillclimb car on e-85, FMIC,GT3582R, 3" exhaust, modified ebay manifold, Turbonetics WG, etc etc made 380whp at about 14psi. When I switched to a "street port" S6 motor I made 480whp at 18psi on e85. Dimitri's FD with GT3582R, upgraded SMIC, pump gas, custom manifold, Precision gate, mild port, 3" exhaust with cat, etc made a little over 400whp (in TN) at I believe 16psi. His is a real street car that sees a few trackdays and autocrosses a year, and just runs on pump gas?
If I can help, feel free to ask!
1986 Turbo FC race car, S6 13b, GOOPY Apex seals etc, GT35R, AEM EMS, lots more good stuff
