Pfc Vs Gcg Hi-flow: R33

[rbee25]

Hi,

I am new to SAU so howdy all

I have recently bought a 97 GTST S2 with the following mods:

Large FMIC, Tein Coilovers, HKS AirPod, turbo back exhaust, manual boost controller (10psi), and HKS BOV; (so relatively light mods).

I am wondering whether to go for a Hi-Flow GCG turbo, or a Power FC. My aim is to get roughly low 200rwkw's (would be very happy with 220). (Obviously on a bit of a budget)

I am very keen to get my turbo hi flowed, but would this be a waste since I do not have an aftermarket ecu, injectors, and fuel pump?

Would these stock items be able to handle the GCG turbo upgrade (with say 12- 15 psi) ?

any help would be great

Thanks

Hi mate, welcome

If you only want low 200rwks, i would say a power fc will get you there fine. Of course the mods you have are fine, but you may need a fuel pump. If you decide to go with a power fc, u'll notice so much more mid range punch just on the standard turbo.

If however, you wanted to go for the GCG highflow, although you dont 'need' an aftermarket ecu, to get the most out of the turbo, you would definitiely need one. The standard ECU wont be able to keep up with the changes in air flow being pushed through the high flow. However, if you keep boost low, then it should be OK.

Ideally, if you could get both, then youd get the most out of the highflow, along with some bigger injectors and afm.

however, if you were to choose one, my adivce would be to just get the power fc. Youd be making the most out of the stock turbo, itd be better on fuel and better for your engine, generally

cheers,

Anton

200rwkw - can basically be done with the stock turbo.

So keep it.

Just get a PFC and a tune and thats all you will need and will see 180-200rwkw depending on the dyno and the day. Either way the GCG is a 250rwkw turbo. So you'll only have added lag/response time increases

yeah for the figure your after the limit isnt really your turbo at this stage its your computer. and the powerfc once bought is there for when you get sick of 200rwkw and upgrade to the hi flow

ok thanks for the advise guys . It seems I will be going with the PFC for now then, and as yousay, if I "thrive" more later, I will have the computer to handle any extras.

Hmmm,, now the hard part.. Where to find those scarce PFC's these days

thanks again

thanks moonus,, i was just looking through there and found a few S1 ECR33 controllers.. would these suit, (even though I have a S2) ??

cheers

hey, i never used a hand controller so i dont have any first hand experience, but i sourced this from another post:

If your PFC is an RB25 model then it will use the FCC NT or possibly the FCC2 model HC.

If your PFC is an ECR33 model then it will use the FCC3 model HC.

If you don't have the right one it will just freeze and show 'Apexi'.

If you need more info then check out PaulR33's Apexi PFC FAQ in the tutorial section.
