saw this in a FB group was interesting the SX-R smaller brother doing this with the SX-R low inertia wheel I would hope it to be right at the 4k mark as you had mentioned Lith

would this be a good fit for a Rb25? what do you think it could make with a piston and rod motor? 600 on E?

I would assume these are a quality name brand in aus? No specs on them on the website they are the same price as just kelford drop in springs

These ones from golebys?

Agreed, just was not sure if RBs had anything that would dictate recommending new base or retainer. Everyone recommends head drain due to oil pooling the head. Didn’t kno if there was a similar thing potentially for valve springs

Hi all Any reason not to get the Kelford Drop in springs for RB25DET NEO? RB25DET NEO “Drop-In” Spring to Suit OEM Retainer Any concerns with OEM base / retainer that would warrant replacement ? RB25DET NEO Beehive Spring | Titanium Retainers I know that Ti-retainers would be lighter / faster on valvetrain making it easier to move.

@robbo_rb180 agreed that is what I have heard for q45. So want to stick to something similar to stock 60-70mm max ( just want something better looking really ) overall for the greddy plenum. @Duncan Chequered tuning made 670 on e85 and said they were very surprised it did that with stock TB and they actually ran out of fuel pump. @Dose Pipe Sutututu Running Haltech 2000 (no DBW)

Hi all what options are there for RB25 Greddy / Freddy intake throttle body must be cable throttle q45 works greddy adapter with stock throttle body I have heard that stock throttle body is best for street driving and is not restrictive for ~700whp level

I think it would more depend on use case for the car while this is a rb25 bottom it makes 700 on a g30-770 so most likely maxed out. This would be a great choice for drift to light up the tires and quick torque delivery. I think a g35-900 would be better suited for everything else as it would probably have a smoother power delivery

Blitz or Otaku garage rb26 to rb25 intake manifold adapter shipped US

I know that greddy will work just wasnt sure if there was any other FFP that may be an in between. of the chin FFP vs the OEM / Plazman top half that may have longer runners

Agreed, I guess I would consider long runner oem or rajab since they have their own runners and they bolt to the oem lower plasman (top half cap?) Mid length (just a collector that uses oem lower) and all the rest short runners

Hi all I have been searching around for an aftermarket Intake Manifold (FFP) Wanted to see if there are any others out there as i have been searching for a few months and find a new one every week or so. Overall Height will be the main concern (cant be much higher then Valve Covers). will be in 300zx Z32 Would like to stick with Long / Medium runner If possible. I may be able to do a cut and shut on the OEM one. Plazman Top half May be an option but could sit to high Hypertune short runner CPC Short runner Greddy / Freddy tried and true short runner Speedtek Racing Cast Aluminum 2 piece short runners Rajab Racing Top half, sits high currently only RB30 but in testing prototype for RB25 as of May 25 IMR Fabrication plenum/runners welded to Oem flange look nice may be an option China/ZERO Fab / ISR / NP Bosted short runners let me know if there are others out there that may fit the bill!

What if i ended up with a T4 Twin scroll Manifold, I was thinking the 45SS1, what size A/R .86 or 1.06? or would you have any reasoning against it. Looking at the Dyno graph it does not appear to be to much different then the 43SS PRO. Obviously may be a bit laggier

t3 with .82a/r?
