Hey,

Ive done a search on this subject but couldn't find anything.

I've come to a fork on the road with my skyline. Do i get a Power FC or not?

Currently i have on my RB20:

185rwkw @ 1bar

R34 GTT turbo

Walbro 255 pump

Filter

Bov

2.5 turbo back exhaust

Apexi EBC

Trust V-SPL FMIC

Chipped/Remapped ECU with maps for R33 turbo

If i install a Power FC how much power will i gain?

Is it worth spending $2000 to buy/install/tune?

Any help would be lovely :rofl:

Cheers

Sean

How you will gain will depend on how well the stock ecu has been remaped.

You most probably won't gain anything up top, maybe a little as it will be able to tuned a little closer to the edge as the PFC has a knock sensor readout.

Mid range is possibly where you will pick up some power, but once again it depends on how well it was tuned with the stock ecu.

I would probably stick with what you have now if you are not planning on upgrading the turbo at a later date.

what an idiot, i know that you will only get a few kw's to begin with but if you continue modding it will be the thing letting u down in the end!

Hey...idiot is a bit harsh:)

I think the previous owner was looking for an improvement whislt keeping it nice and quiet, ie not drony:)

If you want the extra 40-50hp your gonna need the stroker crank i just bought. Its custom made from a crew of brilliantly gifted engineers in the former Soviet Republic...liek the GTRcrank it will need some clearancing of the block, but she will make the power im after:thumbsup:

      RH9 R32 GTR Build Thread

      Out of curiosity, how do you cover up the inspection hole? Surely it doesn't sit open like that, right? With grime and dirt coming in and oil going out?

      M35 Brake caliper replacement

      By Waders360 · Posted

      Hi from Canada, Both of my calipers are starting to fail. My car is a 2005 M35 Stagea ARX and I can't seem to find any parts or any cross reference caliper that would fit my car. Is there a company or a similar caliper that would fit and I could replace the OEM one. Or if anyone knows where I can find a new OEM. Any help is very appreciated. Let me know!

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Maf is a question mark but TPS  I have set at 0.47, the fact that I’m getting proper voltage range out of it with the key on leads me to believe it’s functioning properly. I’m getting proper voltages on basically everything. I still need to look up voltage ranges for z32 maf and test that

      By 25zenki · Posted

      Honestly no not at all, but it’s a very basic tune, it’s stock injectors q45 tps and z32 maf. Other than that it’s a completely stock base map. The file is from nistune and from my understanding if it was tune related I would be able to unplug maf and tps and it would still start even if it was a really shitty start. I have tried starting it with coolant temp, maf, and tps unplugged none of those 3 togethor or individually changes anything
