Just wondering has any one thought or tryed of hooking up

The factory boost sensor to the defi gauge map sensor since

By my understanding they both read the boost

I recently broke my boost sensor ( the hitachi thing that sits on the fire wall

Above the bov) and my check engine light is on and I noticed that

My defi gauge is hooked up to the same vacuum line and it has 3 wires

That go to it

So I was wondering if the def map sensor reads the boost but only sends the

Signal to the gauge what if u hooked the standard wires up to the defi wires

Wouldn't that tell the ecu what boost it's running etc

You can call me dumb or anything thing u like but I was just pondering

And would make life easier and cheaper for loads of people who break

The stupid lil hose that goes to the stock sensor

Cheers Brenton

99% sure it wouldn't work, the factory map sensor pretty sure sends a voltage signal which the factory boost gauge is calibrated to. I can almost guarantee it's not a digital signal

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

      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.

      I was just going to say that it's good to see you picking up the pace again. Hope the surgery goes well. More downtime just means more time to come up with new ways of digging a deeper rabbithole

      Correct part# for coilpacks for a S2 ER34

      By soviet_merlin · Posted

      How do they compare in size? I have the Yaris coil packs in mine and they work fine. But they are either bigger or sit differently so the engine cover doesn't fit anymore. Not the end of the world but not great either. Do the R35 ones sit flush?
