Upgrade time, Turbo or Power FC


Recommended Posts

Its time to upgrade, nothing to expensive, im looking at a second hand HKS 2530,2535 or a Power FC. Im sure the turbo is going to give me the best bang for buck results so im thinking this way at the moment.

I tune the car myself via the SAFC2, and last dyno tune we where pushing out 207rwkw running max boost (13psi) out of a stock turbo. Any more boost and it wasnt a smooth power curve. With the Power FC, i dont think i will be able to get much more peak power, probably a bit more meat in the middle. I noticed a slight dip at 6000rpm in the power curve which we couldnt get out. Ive noticed this on a few other dyno graphs as well with R33's, must be the stock ECU.

I think with a small HKS, we should be able to see 230/240rwkw comfortably even without a Power FC.

Any thoughts?

i'm pretty much in the same boast as you ...

s2, gts-t, with turbo back 3", hks pod, hks boost control ..

my mod list is as follows, for reasons i'll explain

1. power fc - not installed yet, on the way from japan

2. fmic - about to order

2. fuel pump - ordered

3. regulator - researching

4. afm (z32) - waiting till i find a decent priced one

5. turbo or injectors (high flow) - (sigh) expensive

6. injectors or turbo (high flow) - as above

the reaon i am doing it in this order is that i want all the support systems of the engine to be fully up to spec before i go winding up the boost to 'crazy ass levels'

with a 'phat, fully sick man' turbo ... the last thing i want is a melted piston due to the fuel pump maxing / dying or other such sillyness ...

just my 2 pence worth

(i'm a pom, so am still allowed to spend my opinion in £)

:)

How's your current turbo doing dude?

If it's on its way out, easy :) get the bigger turbo. Use the SAFC to lean things out. Then get the Power FC.

If not, I dunno. Personally I think I'd get the computer first.

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
