Hey Justin,

As Sparky & others have said, the type of fuel you plan on using will be paramount in your planning process but I'd also way up where you like your power to come in. Do you like fast spool up & low down/midrange torque or high revs & big top end power? I'd study the different dyno graphs of the BBK, Green/Red (although you didn't cover the red) & also cammed IX's, paying particular attention to accompanying mods each has & what fuel they used for that dyno pull. Look at the spool up, the rev range where they make power & compare it all to what you like about your Evo.

Map out your future goal for your ride, part selection will need to complement that goal. All of the powerful cars we read about were planned out, it has taken careful parts preparation through R&D. None of these cars are thrown together, there's a theme to them all.

If I was in your boots, my preference would be Chad's BBK Full over the Green/Red or cams. I like torque & rarely spend much time in the upper rev range (unless on the track), I'd mainly use pump but it's also shown to be fantastic on E85 too. So BBK full then cams for me.

There's room to grow (if your sig is up to date)......larger cams, ported intake mani & 65mm TB, ported exhaust mani, later on ported BBK hotside if you don't get it first up, bigger intercooler(I like the BR Race ATM) & head work to name some.

Good luck with your decision, either way would be great, I envy the boat you're in.

Cheers Steve

 

Good stuff!

Just curious here: is the BBK-Full a stock-appearing turbo like the FPs?

Thanks and good luck!

 

yes

 

The OP has a IX Turbo, so if he wants a lower price he can ship in his turbo and get it made into a BBK Full for < the $1650 price (I think it is $1250, but Chad will have to confirm). I think that is also an option with an FP Green or Red, but I'm not sure about the prices.

 

steveevo9's comments are cogent. Think of your longterm power goals for the car. The type of racing(Drag vs. Auto-X), or driving(mountain twisties, stoplight-to-stoplight, or highway) that you'll most often be doing. Your car's particular gearing and how that matches up to the engine's powerband, the new turbo's spool characteristics, and how all that matches up to the roads or tracks on which you will be using the car.

Overall look at your longtrem build project and focus on the end result and how the car will dovetail with your intended purpose. Do you mostly drive on twisty roads with relatively short straightaways? Do you drive on highways with sweeping curves and fairly long straights? Do you want to take it to the Dragstrip? Do you value extremely quick spoolup, fast transient response versus all-out topend power.

Will you be running straight 93 octane gasoline, E85, or Meth? What is your ultimate power goal? There really is no one, perfect do-it-all turbo. No one particular turbo will outperform all others in any and all situations, under all conditions and possible scenarios.

I message with a father and son in Texas who Auto-X their Evo. They are running an FP White, which is an extremely quick spooling, stock shelled, relatively smaller diameter HTA compressor, stock sized turbine wheeled turbo. However, for their particular application and intended use the normal White with the 10.5 housing won't spool up quick enough. So they ended up with an FP White configured with a 9.0 turbine housing. This allows the turbo to reach 30 PSI on those extremely short parking lot straightaways. The boost hits extremely hard in a nanosecond.

Just know what it is that you want to achieve, and exactly what youre building it for. The weapon should be chosen to matchup perfectly to the battle conditions. You don't want to try to wield a broadsword inside of a telephone booth.

 

if the core IX turbo is in good condition it is 1250, add 100 for porting and polishing of the hotside

we can have it done within 2 days of receiving it

cheers

buy the red turbo man

 

Sparky, that advice you gave is pretty sage and certainly what these forums should be about. I love the torque that my stock VIII turbo provides and I can't wait to feel that 75whp/75wtq plus once I add the BBK Full/E85 when I get back from Iraq. It sure is going to feel good having that blue beauty waiting in my living room!
