To PFC or not to PFC (RB20)

[Flaps]

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

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.

Thanks for that Cubes.

i'd be gettin rid of that 2.5" exhaust first and putting a 3" on. you'll notice more power there!

I would love a 3 inch exhaust but how much power would i gain? 2-5kw?

Unfortunatly the guy who owned the car before me put on a 2.5

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:)

narc up boys, i would like to know aswell because i just purchased an rb20det power fc for $1099 my 32 has high flowed turbo, hks front mount, 14psi, bosch 040, 3.5inch exhaust all the way through, either gtr or rx7 550cc injectors will be going in soon, and going to get it tuned at 18psi...have never had the computer tuned so hopefully it will have stacks more power when i get it tuned...hoping around 40-50hp...let us know what u think

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:

...lol as Cubes said, depends on how good your current tune is i suppose:)

fark......thats a stroker. probably jus a bit bigger than an rb24. hay.lol

[Cubes]

If I were to do it again, I wouldn't even bother with a 3".

3.5" is the way to go.
