Hi,

Have searched but cant find any firm advice on using the rb25det head on rb30 block, has anyone using this head left the water gallery that doesnt seal by much as standard and had it seal with no problems?

Also is it necessary to feed oil to the front cam journal if i DONT want to run VCT?

Any one got any pics of a head with external oil feed?

Cheers

I havent heard of anyone not welding up the water gallery to provide a larger surface area for it to seal on. It would probably work without building it up, but its just a peice of mind thing knowing it has more area to seal on.

There should be heaps of pics floating around from this being brought up before. For the external oil feed that is.

On our current head we dont have any external oil feed and we dont run vct :)

There's a whole damn thread on this and a full guide on everything needed. Use the search function.

It's in Forced Induction Guides at the top.

      Question about BoV on RB25DET NEO

      It's not as simple as it is being made out to be. It s not hard, but there are things that have to be done. Am busy right now, but will try to essay later.

      Pinout is different to my knowledge, but you should confirm to be sure. Also you will need to adjust the VQ table in Nistune to suit. I would still recommend sticking with recirculating BOVs, I'm not sure if the R35 card MAF will fully resolve stalling caused by reversion/throttle lift.

      What issues are those? Previous owner said it wants to stall sometimes. We did test drive and it was nice and smooth so it will be sporadic or idk. And if i just change MAF(the sensor to R35 version) it should be better? And as i asked...is it like "plug n play" with oem MAF from R34?  This is a MAF from R35 right?

      Even with no BOV you will have issues unless the MAF is a hot film type like the R35 which has some design features to deal with reversion. Hot wire MAFs are very sensitive.

      So i just change the (whatever is inside ma original MAF and slide the R34 MAF (it is gonna fit right in? ) and somewhere on the hot side a BoV...i presume that would be vented to the atmo? I just "trying" to understand...maybe my mechanic would know this   I would not mind(even prefer) to run stock BoV cuz it is way more than fine but i do not have that and only pipeing what is left is oem J pipe ... I will be running Blitz fmic(to fit oem one side style) and i gonna need custom pipes cuz i do not have rest of those pipes and hoses... But i am want standalone ECU. Only choice i have atm is Nistune...but that is not gonna cut it right?I dont know what Nistune can and cant do... I know you guys know Link and Haltech...but whatabout ECUmaster? I know guys in here run those but i literally do not know about that and do not know differences... Just know to take whatever "my" tuner can work on.
