I have a moderatly tuned RB20 with the following mods

Sliding performance hiflow rb25 turbo

GTR injectors

GTR fuelpump

3" turboback, split dump, metal 3" cat

remapped ecu, FMIC ect

I am having a miss when running anything over 16psi with the stock coils (suprise suprise)...

I have ngk copper v plugs gapped to 0.8

Currently with 16psi the car is making 215rwkw. If I wind up the boost to 19psi it will not miss the first 2 runs and it makes 230+rwkw. the car also feels quite a bit faster. after that it all goes to s*^t

Should I stick with 215 and stop spending money or shell out another $600 for spitfires and be able to run the full potential of the turbo and make around 230rwkw

Is 15 kw worth $600?

or should I gap the plugs down further?

put the car back on the dyno today and had bad results due to the coilpacks.

The car only made 204rwkw due to only being able to run 13psi. the car did manage to make 5200n tractive effort but was serverley hindered by missfire.

the afr was perfect on 12:1 from 4000 to redline. so that and the 10 votes for spitfires and none for stockers :/ I have ordered the spitfires.

Really hoping for a solid gain and ability to run 18psi. The funny thing is I was able to run 18 for about 3 weeks and the coils have gradually gotten worse.

the car made 230 before the coils fuc$%d out so thats all I am shooting for.

I wasted hundreds of dollars with secondhand coils and remote coil setups, none of which solved the problem.

Haven't had 1 miss since installing the splitfires

DOOOOO IT!

I found perfectrun to be the cheapest - $535 delivered

      Need to see other side of PCB in that area...ie; I don't see any thru-hole mounting, just soldered vias (smd zeners in SOT23 have 3 legs but only 2 are used, as reflected by PCB tracks)

      Another "where do these lines and plugs go" RB25DET question

      4 to 5 is fine. It will be slow, but that's better than blowing turbos. I don't have a PS pump idle up solenoid on my car, because... I think when we put the Neo in we retained my R32 lines. But.... From inspecton of the R34 vacuum hose diagram, you can see that the solenoid needs to be connected to the turbo inlet as source of clean air) and the plenum (as source of vacuum - which is the place for the air to flow to to cause the idle to increase). So 3 to 1 is VERY WRONG. 3 should go to either the turbo inlet, or the plenum. Follow the other hose from the PS solenoid and if it goes to the plenum, then your 3 goes to 2 2 would also serve as a bleed port for a boost solenoid.

      Pull them out and pull more apart. You can't do shit with them still bolted to the floor of the car.

      Yes it is. ZD1 is on the other side of the board. Where ZD1 is marked is clearly opposite a 2 pin device. Our 3 pin device here is not a ZD.

      Tein Circuit Master- rebuild worth it?

      By QB6SAGR · Posted

      Alright, a little update on this... I called Fulcrum, who used to be the distributor in Australia. No Bueno, they don't service them anymore.  Called shock works, who don't service them but offered to dyno the shocks for performance, and suggested DNA in Sydney might service them.  Called DNA, who also do not service them and basically said they try to steer customers away from tein for this exact reason these days- there is just no support for them anymore apparently.  Both SW and DNA said they are a not necessarily a bad product, but they just don't service the brand or know anyone who does service the brand anymore.  So... I could keep calling around but at this point I think I'll probably just spring for the shockworks product, unless anyone here knows anything.  Cheers 🍻
