You need to be a bit more specific, there is a coulpe of 25 heads to chose from, I believe the one you want is from a R34 RB25 NEO.

VCT and solid lifters.

Shop Smart, Shop S Mart.

its for my farther inlaw i havent reseached it he has just asked me for a rb25 head.why does it need to be a r34 head off a neo?why cant it be off a series 1 or 2 r33?cheers

The NEO head has solid lifters which will be able to rev higher but it still retains the VCT so it revs quicker.

You can also restrict the oil in the head more due to not needing oil to pump up the hydrolic lifters.

Theres lots of threads in relation to this, have a bit of a search around the RB30 hybrid thread in the forced induction thread.

    • Sounds good.  I don't 100% understand what your getting at here. When you say, "I keep seeing YouTube videos where people have new paint and primer land on the old clearcoat that isn't even dulled down" do you mean this - there is a panel with factory paint, without any prep work, they paint the entire panel with primer, then colour then clear?  If that's what you mean, sure it will "stick" for a year, 2 years, maybe 3 years? Who knows. But at some stage it will flake off and when it does it's going to come off in huge chunks and look horrific.  Of course read your technical data sheet for your paint, but generally speaking, you can apply primer to a scuffed/prepped clear coat. Generally speaking, I wouldn't do this. I would scuff/prep the clear and then lay colour then clear. Adding the primer to these steps just adds cost and time. It will stick to the clear coat provided it has been appropriately scuffed/prepped first.  When you say, "but the new paint is landing on the old clearcoat" I am imagining someone not masking up the car and just letting overspray go wherever it wants. Surely this isn't what you mean?  So I'll assume the following scenario - there is a small scratch. The person manages to somehow fill the scratch and now has a perfectly flat surface. They then spray colour and clear over this small masked off section of the car. Is this what you mean? If this is the case, yes the new paint will eventually flake off in X number of years time.  The easy solution is to scuff/prep all of the paint that hasn't been masked off in the repair area then lay the paint.  So you want to prep the surface, lay primer, then lay filler, then lay primer, then colour, then clear?  Life seems so much simpler if you prep, fill, primer, colour then clear.  There are very few reasons to go to bare metal. Chasing rust is a good example of why you'd go to bare metal.  A simple dent, there is no way in hell I'm going to bare metal for that repair. I've got enough on my plate without creating extra work for myself lol. 
    • Hi, Got the membership renewal email but haven't acted yet.  I need to change my address first. So if somebody can email me so I can change it that would be good.
