Do all rb25 heads including na use the same ports and bolt pattern for the intake and exhaust manifolds? Could i get a r32 rb25de head and put my r34 neo manifolds etc on it???

yes all the 25 head have identical intake patterns and ex patterns. yes the neo manifolds will fit same.

No.

Please know what you're talking about before you post.

The R32 RB25DE head has the same intake bolt pattern as the RB20DET. R33 RB25DET intake manifolds and R34 RB25DET Neo intake manifolds DO NOT BOLT UP.

Exhaust side, RB20/25/25neo are all the same.

To the OP, why would you want to get an R32 RB25DE head and put your Neo manifolds on there? if you're looking to build a 25/30 then you're better off sticking with the Neo head if you already have it :)

      Installing the fuel sender O ring in R34 GTT

      Wish I had this advice when I did my pump. It went in and out 3 or 4 times, and on the last time it snapped.

      Tried them, they leaked. I also foolishly bought some random rubber ones that leaked too.  Genuine and not looked back.    As always though sample size of one, and I could have made a mistake installing them.

      Shit job but not hard. I'd use a piece of wood to knock the plastic lid open to avoid damaging it, use a vacuum to clean up the fuel sender lid also so crap doesn't fall in. I'd probably do pump and filter at the same time since you're already in there, I reused my OEM sock after a quick clean since the one provided wasn't long enough. Could also hardwire your pump if you feel inclined.

      Supercheap auto sell this: https://www.supercheapauto.com.au/p/pat-plusquip-fuel-tank-lock-ring-tool---universal-kit/SPO3564082.html I own this and if you HAVE PATIENCE you can remove it without snapping lines and generally being incredibly angry, then said at doing this job. Sadly I've removed the pump about 75,000 times over the years. I don't know if you're a large lad or a smaller lad but my advice to you as someone who is 185cm is if you are my height or smaller, is to sit in the boot and take your time. Yes you can put the seal on. The seal goes over the white thing/lid (you will see how it 'slots' in) then the whole assembly presses into the tank. then you screw the lock ring on. I spent so much time doing things the wrong way by trying to mount the seal into the tank first, then putting the white fuel hat on in the space provided. Put it together first then it'll all go in. But seriously be careful about removing the hoses AND where the removal tool is moving relative to the plastic pipes coming out of the lid when you've removed it. IT IS BRITTLE So brittle in fact I have two spare lids, and would recommend buying a spare and having it handy before attempting to do this. May as well throw https://justjap.com/products/deatschwerks-dw300-fuel-pump-nissan-s13-silvia-r32-r33-r34-skyline-c34-stagea?currency=AUD in the tank as well, as this uses all stock plugs and such. You may need to/strongly recommend you re-use your OEM fuel sock or use the one supplied with a length of hose so it sits at the stock height.
