This means I could sell my 20G-9 with the hotside & actuator. yay

Good question. I asked Dave earlier in this thread if this turbo came with an upgraded actuator and he replied that it did. Robert @ FP also indicated during a phone conversation that the Green turbo will contain the 17psi actuator.

Mystery solved. The FPGreen/LT turbo will not (by default) include the 17psi actuator. It was thought in the conception phases that the 17psi actuator would be utilized, but in order to keep the turbo as stock-appearing as possible, FP has elected to retain the stock actuator unless requested by the customer to upgrade (for $65).

The turbos come with a standard EVO9 regulator. The 680's are border line, I think they will fine. The turbos come with a 10.5 housing, a normal 10.5 will not work.

Would FP be willing to supply a compressor map?

I'd like to see how the efficiency changes with the new housing and billet wheel

So would a person be well adviced to upgrade or is the EVO9 regulator fine? I will be running Meth on the street, 27psi, and race fuel when I race, 30+psi.

Well, according to the FP website it says "Applications running high boost such as race gas or methanol injection will benefit from the extra spring pressure. Using the HP actuator will result in retaining more boost higher into the RPM range compared to the stock actuator (11psi). "

What about the second option of porting the turbine housing for $45. Is this necessary and/or recommended?

I was recommended by Nick at Buschur to run 880cc to be sure and have enough fuel with high boost on race gas. I think its alittle over kill but i have a EMS so it not really a problem if they are to big.

Port it your self for the $45

dave what size injectors are you suggesting for a flashed ecu.... 720's, 750's, 880's, 1000's ??

We charge $50 for porting of a new turbo here. If you want to port it yourseld, please do

The stock EVO9 actuator works very good. We were sending turbos out with the HD actuator but too many guys could not get their boost low enough using that actuator. So my recommendation is IF you are running alky or race gas all the time then you may want to use the HD actuator. If you plan to run pump gas and 22 psi or less then stick with the EVO9 actuator. You can actually put pre-load on the stock actuator and make it work really well.

880's, if you have a stand alone are not overkill. As a matter of fact I would have recommended 1,000 cc injectors so you won't have to upgrade again.

For a reflash, I don't know what the car is going to need for this new turbo. 680's on race gas and a car that makes all the power that is possible with this turbo probably won't be enough. 780's might be but if you buying 780's you may as well step up to 880's. There are some guys that have 1,000's running good on a reflash now so you may as well go a little on the big side, 880's sound good.

David, what will the stock acuator hold till redline? And what will the HD hold till redline? And what is minimum psi that can be run with HD actuator?

David Buschur

The boost to redline with this turbo should be good with both units. The biggest thing the HD actuator does is adds a lot of low end torque as it doesn't blow open. With this turbo I'd say 30 psi to redline is possible even with the stock actuator and a turn or two of preload on it.

The minimum PSI with the HD actuator varies, if you pre-load it I'd say it's over 22 psi.

I'm running the FP upgraded actuator on my IX turbo now, and with 2mm of preload, and the EBC turned all the way down, it will boost to 18psi (70*F ambient temperature @ sealevel). The Green/LT turbo should respond similarly to the standard 2mm preload.

I honestly can't see this turbo holding 30 psi to redline, it just doesn't flow that much air. A 2 liter at 8k rpm with all the usual airflow enhancing mods will approach 55 lbs/min. I'm estimating this turbo will drop to 26 psi or so over 7500 rpm. But as I have said many times before, it doesn't matter what the boost pressure is if the compressor is maxed out. You are a little better off if it happens at lower boost anyway, since pressure is heat, even with 100% efficiency. On race gas this will not have an appreciable effect, but on pump gas it can, depending on intercooler efficiency.
