Rb25det Setup And Ideas

[muzziak]

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

Forgot to add, looking for 300rwkw

lol Ben

E85, no need for cams. I make nearly 100kW more than you just on E85, stock cams and the same turbo, actually an older version of it.

[muzziak]

Would love E85, but the cars a daily and can't dual map the PFC so it'll be difficult to work with. Could cams and external gate bump up the power or would it just be a waste ?

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].

[muzziak]

Yeah I've been told I've falling short of the usual mark with the SS2, don't know why. Was hoping the direction I was planning would crack the 300

new manifold and go external, you should be able to add more timing

[tridentt150v]

Yeah, I forgot lol - I have an extrude honed HKS cast low mount and external gate, so thats a big oops!!!

also put stock wheels with non sticky tyres on the dyno.. you'll read higher.

[muzziak]

Seems to be a lot of varying opinions on the effectiveness of adding cams, will definitely go external though

[Dose Pipe Sutututu]

get a better ECU, run flex

I run 98RON most days and days I hit up the track I bring down 4x jerry cans of E85.. smash that, then drive to the servo and cruise back home on 98RON.

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.

[muzziak]

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 ?

[tridentt150v]

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.

I agree with this.
