Hey everyone, I removed this RB25 neo NA from an R34 GT. I want to make it turbo and put it into my R32 4 door. I have all the bits sitting arround so i want to try do it cheaply. Its got 53 000kms on it, so first thought was maybe put a thicker head gasket on it and put the stock turbo set up from the r32 onto it, and run low boost. But then it would not cost too much to put an rb25 turbo bottom end into the non turbo block and make it a VVT rb25det. Im just wondering weather i would need to get pistons only , or do i need to get turbo pistons and rods from an rb25det?. i would also use the box from the NA r34 which looks like an RB20det gearbox. sitting arround i have a rb25 greddy copy plenum , rb26 injectors, car has hks exhaust and front mount. Any suggestions appreciated.

Cheers, Mark.

I'm fairly sure the plenum won't bolt up to the Neo N/A cylinder head.

Just leave the bottom end together and run the normal 12-14psi from the stock turbo. You won't have issues, it will actually make more power.

cheers mate

, Bummer if the RB25DET GTR style plenum doesnt fit the RB25 neo N/A head!, Can anybody confirm this ?

      One Headlight isn't working - Driver Side Fuse Keeps blowing

      By GTSBoy · Posted

      That's a short. Find the short. It will be somewhere between that fuse and the headlight. Start by removing the plugs from the back of the headlight and dimmer switches, and measure resistance to earth. Supply side (power from the fuse) should have none. The other side should have resistance compatible with whatever globe(s) is there (which is relatively easy to say for a normal globe, perhaps not as easy to say for LEDs). Anyway, if you have very low resistance, you defo have a short. Then you just have to run the wiring like you're running the bowel of a dog (on the operating table) that has swallowed something it wasn't supposed to.

      One Headlight isn't working - Driver Side Fuse Keeps blowing

      By kevboost7 · Posted

      Hey guys, need help figuring out why my driver side (RH) fuse 15amp keeps blowing. The Driver Sides Headlamp is out, i replaced these a long time ago with LED ones that were working for 1-2 years. Now, the driver side light is out and i traced it back to a broken fuse. I replaced the 15 amp fuse in the engine bay and as soon as i flip the headlight on, it blows the new fuse. Any idea what's going on?

      I found the same with Subaru’s.  I own and love the SG9 Forester, after that model 2008+, Subaru threw the ugly stick at all their line up and somehow managed to make them look worse with every succeeding year.  lol

      It's something we all have to consider as time marches on. Also consider lifted rally MX5 conversion at that point.

      I should be fine for a few more years, whilst I do have arthritis I also exercise and do mobility training every day to keep as fit and healthy as I can, military life, which is the actual cause of most of my joint issues, has set daily regimes, which I weirdly enjoy I also train alot smarter now, not really focusing on lots strength or puffy muscles, I'm more focused on maintaining what I have for my future older self, I actually train as much mobility now as I do exercising Check out this "simple" drill I have been doing daily prior to training now for a while now, this has worked wonders in my all round mobility
