So building my motor, I still don't know what turbo(s) to get. Is there a company (va speed, millenium) that I can pretty much pay them for advice? Basically , give em all the specs of what I'm building, and they suggest a setup that would work for my goals?

Thanks in advance,
Joe

...post your setup on here.

kyle h.

why pay for advice?

Aight, here is what I have

6 Cylinder (3.8L)
Stroke: 3.4in (86mm)
Bore: 3.8in (97mm)
Compression Ratio = 8.0:1
1.6 Ratio Rocker Arms
Cam Specs; duration @ .050": 223º/214º, lobe lifts: .338"/.332", valve lifts with 1.60:1 rocker arms: .541"/.531", lobe separation angle: 116º, intake centerline: 110º


Forged Diamond Coated pistons
L32 Connecting Rods

Everything else is beefy, full port and polish and all the other go fast goodies.
Looking for a 16-17psi daily and 24 race.

I want something to give a strong strong pull yet keep streetable and not a dyno queen. Any setup (single or twin) is fine.

Lemme know if you need any more info.

i wouldnt suggest millenium, a couple ppl in my racing team had their turbo pipes done there and they were fucked up, as far as anything else i dont know how they do.

I'm not asking for them to fab it, rather help me with turbo selection. Thanks

What type of power are you going after? Also we need more info. What you provided is helpfull but what does the head flow and what does the intake manifold flow. How high are you going to spin it out (rpm)? What chassie is this in and how much room do you have for piping and intercooler?

Intake is kind of going to be custom, so honestly, I wouldn't have any numbers on it. Motor will spin 7k, going for 500 rwhp. Its being put in my Fiero, and theres room, but not much. Intercooler is gonna be up front where as motor and turbos are in the back (mid engine car). I can make whatever work pretty much. Here are the flow numbers I found;
Intake (28" of water, clay radius to repeat)
.100" - 69 cfm
.200" - 127 cfm
.300" - 175 cfm
.400" - 208 cfm
.500" - 224 cfm
.600" - 235 cfm
Exhaust (28" of water, 1.75" pipe to repeat)
.100" - 60 cfm
.200" - 117 cfm
.300" - 172 cfm
.400" - 199 cfm
.500" - 212 cfm
.600" - 222 cfm

I would recomend twin gt28R's. I would also recomend looking into an air to water intercooler and keeping everything in the engine bay or the rear trunk. If you want to look at a singal the I would look at a gt35R/t67, gt40, TO4R or TO4S. Good luck with your project sound like it should be fun when it is complete.
