Haha thanks for the advice. There's so much to read and so many threads. I wouldn't want to have no oil pressure at idle that's for sure. Or 150psi at idle, or catch can filling up. Just wanna drive it like its stolen/to the supermarket.

I'm just gonna make my own adjustable setup both on the pump and on the side of the block and fine tune it from there. It's gonna take all the guess work out. Also it would be a prick to hav to take it all out again for the sake of about 40 bux worth of fittings.

How you going to have external adjustment on the head feeds?

Probably a needle valve of some sort. Drill 2 holes in the side of the block before it gets to the head, one out and then one back in. It seems pretty basic to me. Haven't put to much thort into it yet. I'm sure someone would have done it befor

I've chosen 1.5 middle blank the rear and 1.4 to external feed my non Neo head. Hope it's ok.

I know it's the wrong thread but I've already got my head recond. But haven't welded the water jacket. Gonna grub screw the oil feed. With my rb30 head gasket there's only 1.5 mm surface area on the side of the water jacket. Has any one had done it this way and had success? It's kinda tricky where I live to get it welded and skimmed. The freight would be the cost of a second hand head.

i chose 2 X 1.5mm tomei restrictors and the feed for VCT, could be wrong but mine is a street engine and i like the idea of plenty of oil cooling the top end plus the RB30 pump runs the top end of RB30 with 2.4 restrictors so its still a big difference.... oil cools shit down so unless you on a track then why go so restrictive..

Can anyone confirm if the factory rb30 oil restrictors have a one way valve or its a bullshit rumors

I have never heard that rumour but if the restrictor is around 1.5mm it would be a miracle of miniaturisation and what on earth would be the purpose?

      Its a 2002 vr-x four VQ25DET, silver. Coil overs, lowered, polished alloys and sport exhaust. Bit of a project, was sitting in a shed for a while but runs and drives great.

      I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.

      Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
