Am new to this forum and was wondering if anyone could point me in the right direction towards some knowledge

have a forged rb30 running a built s2 2.5L vct head, valves, springs, porting, 262/272 9.3mm cams, ect 

was wondering the kind of response im going to see from the 6870, have no real power goal in mind, but am trying to make it as responsive as possible with this sized frame turbo. Am hoping for full boost at around the 4,200rpm mark. Have seen 2.6L achieve full boost at 4.5/600rpm so was thinking with 3L + mild cam + vct it may assist ? Car is street car + the odd drift event.
 

twinscroll twingate 6boost, ts 40mm’s x2, 6870 1.00ar, 1650cc with the option of flexfuel, also dbw so things like antilag can be considered. 

just after some knowledge, advice and comparisons not here to get roasted 👍🏽
any help is appreciated

Seems like you have pretty realistic hopes by my estimation - of course depending on what you mean by "full boost".   I'd expect there will be "good boost" by around 4000rpm, especially with VCT... should be a really nice setup

      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

      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.

      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
