selling my rb26 race head, i changed direction with my engine, after experienceing electrical problems with the gtr putting it in a workshop for a very long time and after alot of thinking deciding to change a few things, so hence the sale. i had a new head built for my new setup.

seen about 1500-2000km driving and dyno runs

was part of a setup that made 565awkw @ 21psi on pump fuel, so the head is good for it and is really really strong.

looking for around $7500, which is merely half of what it cost to build! needs to be sold asap to fund new setup.

Parts list:

Ferrea 1mm oversize stainless valves

Aftermarket valve guides

Apexi V-Max SPL springs, retainers and buckets

Apexi V-Max SPL 280 deg 11.5mm lift cams

Tomei camshaft stud kit

Trust cam gears

New stem seals

whats been done to the head:

Ported intake + exhaust runners

Profile guides

Polished + cc'd chambers

Unshroud valves in chamber

Flow benched and runner flow equalised

Steam hole modifications/water gallery modifications

Clearanced for high lift cams

Drilled for 1/2inch head studs

Flow figures:

Lift Int Exh

0.1 100.4 94.5

0.15 147.2 134.8

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      Ok thanks..that was my second question if i can somehow bypass this even with Nistune(that is all i have right now...aparat from stock ECU. So with some aftemarket it can by "bypassed" or make it work?  I know there is Link or Haltech (mainly used). We have ECUmaster here so i will gather some info about it.

      Yes. You will need to get the original boost sensor and wire it in. That is.... if you plan to use a stock ECU - even a Nistuned ECU. The Nissan ECU will not operate correctly without it connected. And yes, it will do annoying stuff like you are experiencing. You will almost certainly be better off with some aftermarket ECU, than trying to hunt down rare sensors.

      Ok so ABS/TCS is "not" the problem. Yeah i know now about the ABS with Nistune(i told that to the Nistune guy) but iam not 100% why or why i dont have ABS. ABS cube is in the engine (always has been) but i had braked couple of times rly hard and brakes just locked and scream. Does all Skylines have ABS cube? That boost sensor https://www.sau.com.au/forums/topic/367633-wtb-r34-gtt-turbo-pressure-sensor-pics-inside/ Is this it? I need to ask but i have a picture of engine bay and i do not see that (100% is not in that place) If i do not have this the car can do what mine is?(cutting around 4000 rpm) Here is the pic of my engine bay(only one i have) BUT i think i dont have that cuz loom was used from my RB20DE NEO and i know (obviously) that it does not have boost control or any wire to that...) so maybe that is the problem? (i dont know for 100% if that car where the engine is from had that)...but i dont have the loom from that

      S1 rb25/s14 starting problem

      By MBS206 · Posted

      I'm with you here. It's either loom has an issue, OR, injectors are not functioning properly. It could even be they're just constantly dribbling, hence the wet, but not firing.

      By Duncan · Posted

      Depending on how long the car sat it is very possible for injectors to be stuck open or closed, I'd get them cleaned and flow tested. Other than that, obviously when the loom changes and the car doesn't start any more....the loom is suspect so some tracing / comparing may be required
