the wastegate actuator is around the 7psi, but if you have a full turbo back exhaust you may get around the 8-9psi mark

Although my bros gets 7psi with no boost controller and he has a turbo back exhaust

Get a decent boost gauge (not a defi copy) so you know what boost you are actually running, and if you only want around 10psi get a turbosmart bleed valve or a gfb atomic boost controller (no more than 80bucks) and that will do the job nicely untill you can afford a ebc.

gt-ahhh! Proficient

The stadnard wastegate actuator is actually 4.5 psi (on my standard car with the two stage bleeder disconnected).

really?!

im pretty sure its 5psi low, and 7psi high boost. and if you have a/m zorst etc, it might even be a little higher.

im no expert on the issue, but ive heard that from just about everywhere.

i havent got a gauge on mine, but its quite obviously more than 4.5psi. the power surge and the racket the damn thing makes when it blows off!

the stock boost level can vary from skyline to skyline, things like different mods can make a huge difference

My bros runs 7psi with nothing connect but a vaccum line (he normally runs a bar through it), but either way you'll need some sort of boost controller to get to the magical 10psi mark and a simple bleed valve will do the job

I'm about to fit up my new turbo back zorst (split front/dump pipe), fmic, apexi pod + heat sheild & CAI ...

What do you think boost will be with these modz?

I spose i wont know until I hook all this up what the boost is going to be but anything above standard without a retune of the ecu is going to cause my ecu to run rich isn't it?

Do you think reseting the factory ecu for now will suffice until I save enough to chip and tune the factory ecu? or should I crank out the credit card?

Hey MANWHORE how much you want for that actuator? PM me :D

      @soviet_merlin Thanks mate!  Nothing too major but will hold me up for a while. I've got lymphomas to get taken off the back of my neck and the middle of my spine which always conjures scary thoughts!  It sounds worse than it is. Yeah great, conjuring more rabbit hole deepening , just what I need! 🤣

      I'd argue the F50 kit I got is very good value. For ~2k I got the calipers (refurbed condition), adapters, pads, brake lines, rotors, and top hats. I think you'd be pretty hard to get Evo/GTR/350z brembos + the additional hardware for similar money. Used market for a pair of front calipers alone I've seen tend to run anywhere from $1500-2000 depending on condition.    That said, something like a GTR or 350z brembo is a lot easier to adapt to the Silvia.

      Is there a significant price difference between the Evo/gtr/350z brembos vs the F50? Looks amazing.

      R33 fuel setup

      I was actually being a tightarse at the time LOL... My OCD is tickling me into running a 2nd 8AN Teflon hose all the way down and removing the 2x OEM hardlines. My other side of my brain is telling me to run 2x hardlines front to back (also acts as a fuel cooler, so win win).

      As I mentioned in an earlier post, I had some trouble with the Silvia's brakes dragging back in 2023. I managed to sort it out then, but the same problem came back to bite me late last year. Just take a look at the picture – I had a feeling the handbrake was acting up again, and I was right. Anyway, I'd been wanting to upgrade to bigger brakes for a while. Not that the Silvia's brakes were bad, but it was more of a "want" than a "need", you know? It was funny, though – at the time, I couldn't find any Evo Brembos, 350Z Brembos, or GTR Brembos for a decent price (of course, tons of them popped up online after I already bought my kit!). I ended up going with an F50 Brembo kit, which came with adapters, brake lines, 330mm rotors, and top hats. The F50 Brembo caliper was used in a few other cars too, like the FPV. I also decided this was the perfect opportunity to ditch the Silvia's ridiculous rear brakes and that awful handbrake (some of you were definitely right about that!). I picked up some R33 calipers and all the necessary bits – rear drums, backing plates, and new hardware to refurbish the calipers. Of course, it wouldn't be a project without a few hiccups. Turns out the brake master cylinder was playing up and basically (to put it simply) keeping the brakes engaged. I had it overhauled, and after some adjustments, everything was working again. The whole process took a while, as you can imagine. To top it off, the front right wheel bearings were shot and needed replacing too. This is a rare occasion where I'm posting an update while it's all still fresh! These pictures were taken just this afternoon.
