Going along the same lines as the NEO post, was looking at going further in my 33 and thought I'd get some ideas. Current setup;

-Hypergear ATR43-SS2 .82 rear internally gated

-FMIC 76mm thick

-Power FC

-3" turbo back exhaust (empty cat)

-splitfires coilpacks

-Z32 AFM

-3" alloy intake with a pod

-walbro 460

-denso 550cc injectors

-gizmo ebc

From the top of my head.

Tuned by Unigroup engineering at 18psi it made 255kW on pump, the actuator couldn't hold 20 properly.

I was thinking cams(tuner recommended), cam gears and going external wastegate as the next step, alongside bumping up the boost. Wanted to get feedback and ideas, with going e85 being the last option

Thanks

I have pretty much the same setup [GT3076 vs ATR43-SS2] and I get 300. But I have cams and WMI to get there [no flex out here].

Cam gears are a waste on RB25's, Tomei cams are set to zero anyway. Cam gears are only useful on a 26 [for road use].

Did you get your dodgy actuator spring replaced? Assuming you have VCT working an adjustable cam gear on your exhaust cam could net another 5 - 7kw.

Why not run fulltime E85? Just run your tank empty - fill with E85 and retune.

I haven't replaced the actuator yet, the plan was to go external soon so didn't see the need.

E85 is the easiest power option, the cars driven quite frequently though so fuel economy could be an issue. With a 33 gtst would the fuel lines have to be replaced for E85 ?

What are the potential power gains from cams, gears and external ?

Forget gears.............don't waste your $$$, you don't need the adjustment for Tomei [and prob most other] sticks. Cams and external depends on the setup you use, but from 255 to 300 is a big step for that.

I'd prob go external first and think about cams later.

    • 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?
