Hey guys I'm taking my car to the tuners again in the near future and need some advice on what to run psi wise through my wastegate and ebc so I can buy some springs. I've been told to get springs for the wastegate that would be 4-5psi less than what I'll run the ebc at when I want higher boost. What boost would be suggested for my setup ??

Just an update on what I will be running;

Current r33 rb25det unopened.

Bosch intank 040

adjustable BOV

BP Ultimate

POD

Power FC

3inch exhaust (dump/front/decat) - 3.5 decat back to cannon

FMIC

Greddy Plenum

GT3076r .82a/r

Turbosmart 50mm Progate

Fuel rail to suit top feed injectors

siemen 700cc injectors

Z32 AFM with tomie plug

6boost highmount manifold

EBC - Greddy profec II

Snow performance water/meth injection

Tomie cams

Cam gears

Gaskets -intake and exhaust

Fuel reg

Splitfire coilpacks

Catch can

Water/oil lines for turbo

New dump pipe and wastegate dump to suit

Think that's about it. Any help is appreciated.

Cheers

I see a big list of parts, but I don't see your goals or what you'll be happy with?

The usual answer to that question is As much power as I can run safely.

In which case, you take it to the tuner and see how it goes.

I'll bite and throw out a figure of about 19/20psi high boost. So get the wastegate acuator set at 15 or 16psi so you don't need to bleed off too much with an EBC.

9000 :P

Your running water/meth so push it and see what it likes, on 98 I run 18-16 psi which is 311kw but with E85 (assuming WMI is similar) I run 21-18 psi ad run 357kw, this is a stock RB25.... So see what your tuner is happy with..... Oh and the gate spring is 1 bar.....

    • It was roughly 3.5 hours.    car went in around 11:00 and I was done around 2:30 He did the initial runs, install the BC and then Nistune install and tune.  The best part was sitting in the lobby and hearing the skyline on full throttle at the dyno 😂😂
    • Glad it all went smooth. How long did the tuning process take?
    • Yeah that was kind of the same feedback my tuner gave me.  the boost tee is until I can sort out my plan for the electronic boost controller and what I’d get, where I’d mount the dash etc.  I’m happy with this until I can figure it out. Not a big fan of the A-pillar gauges. I’d like to get a clean install of the boost gauge - something digital like GFB.  Something like that might fit neatly where the ashtray is and look clean. I feel like replacing the OEM triple gauge is a bit extreme for a weekender like my skyline. And it’s not making crazy power to need all the additional sensors/gauges. 
    • I'm about to swap my box to Tremec T56 Magnum F & initially thinking of re-using my DCS twin plate (can get it re centred for the bigger spline) but it's been called out the box will be noisy (rattle) as the clutch is unsprung.  So I'm doing as much research as possible. I'm not so worried about holding the power as I'll go the track version which on paper will hold the maybe 1000hp I make. It's the longevity I worry about. DCS told me they don't use a sprung centre as it's just something that can break. The uni clutch has a very complicated sprung centre. Any one had or heard about any issues with it failing? Thanks in advance.
    • Auto is at least 10% (from my real, actual experience with different torque converters and manual on the same setup) ~185rwkw at 11.6psi (peak!) is entirely what one would expect without a FMIC or anything else on the intake, it does bleed off towards the higher RPM so it's what, 9psi there? Note: There is nothing that can be done about this with a manual boost tee. If you want to hold it steady and gain more top end, well - You will need electronic boost control.....
