R32 GTR Drag Cylinder Head

 Hi all,

New to the forums after a little advice regarding my rb26 head build.

Im currently building a r32 drag car and im looking at building a head that will support 1300awhp+ , before anyone asks the rest of the engine and driveline will be capable of the power im chasing i just want to do the head right the first time around

I will be starting with a new core.

Im thinking about going sum custom cams but unsure who does the best for this sort of an application.

What i would like to know is who in australia does the best porting jobs on the rb26 with proven results.

Also suggestions on the valve train im looking at ferrea 1mm oversized valves but not sure on what are better in the way of spring and retainer kits. Are ferrea, tomei, and supertech all pretty similar in quality and performance?

Are tomei solid lifters and bronze valve guides going to be up there with the best or is there better available?

Also ive heard of +2mm oversized exhaust valves being an option but unsure of who makes them....

Any advice or help pointing me in the right direction would be greatly appreciated.

Thank you

mate,

after getting in touch with the owner of NAPREC and exchanging about 30 emails... .ive just sent a head off to NAPREC in japan which arrived to them the other day. what i'm getting is JAPANESE precision...you cant get that in australia.

the head getting ported & polished to within an inch of its life to bring out the goodness in the +1mm BIG valves.... and the squish is also getting thrown out the door in favour of the legendary hemi chamber

no need for squish when aiming for brute power with no concern for emissions : )

also, you'll want to change the valve seats for 1000ps+

 

food for thought.

      Nismo GT Pro LSD configurations

      No, you're wrong, and you've always been wrong about this. The Nismo has 2 sets of openings. One is a real 2-way, and the other is a 1-way. There is no 1.5-way possible with the ramps that they offer. A real 1.5-way does exist. That Cusco stuff I posted is a prime example. If the forward drive ramps are, say 55°, and the overrun ramps are, say, 30°, then you will get about half as much LSD effect on overrun than you do on drive. It is real, it realy works. OK, you're slightly right. The Nismo has 55° and 45° ramps on the 2-way, so it does offer less LSD effect on overrun. But, I think that just means that they've (probably) sensibly established that you do not want actually equal LSD effect on overrun. You just want "quite a lot, but not quite as much as the drive LSD effect".

      Nismo GT Pro LSD configurations

      By Kinkstaah · Posted

      Yea, that is what I was getting at in my ramblings too. The nismo one actually is a 1.5 way and a 1 way. They don't do a *2* way because a true *2* way would have equal ramp angles. Or is that a true 1.5 way? Realistically I think a "1.5 way" does not actually exist. A diff can either lock in two directions or one. It also doesn't help that a LOT of people in Australia speak about 1.5 way diffs are referring to their 1 way diff.

      Nismo GT Pro LSD configurations

      By GTSBoy · Posted

      Well, the trouble with that ^^ is: The configuration shown is absolutely a 1-way, not a 1.5-way. There is no way that a 1.5-way can be said to offer LSD action only on acceleration. If Nismo cannot get that right, then it is impossible to believe their documentation. That ^ is not a 1.5 way setup. That is a 1-way.   And so now I have allowed all doubts to flourish and have gone back to look at the MotoIQ video. I originally made the mistake of believing him when he said "this is a 1.5-way" at the ~6:10 mark. Because what he did was take the gear assembly out of the 2-way opening and just rotate it one place to the left to drop it into the 1-way opening. When he dropped it in there, the cam was "backwards" compared to the correct orientation shown in all other photos of that config. The flat shold have been facing the 1° ramp side of the opening, not the 55° ramp side. And I thought, "gee that's cute", but I was concerned at the time, when he put the other ring back on, that the gap between the rings looked like it was wider then in the 2-way config. And then I said a lot of things in my long post on Tuesday that could only make sense if the guy from MotoIQ was correct about what he'd done. BUT... I have now done my homework. I grabbed a frame of the video with the 2-way config, and then grabbed another with the "1.5-way" config, snipped out the cam and opening of that frame and just pasted it direct on top of the 2-way config. I scaled it so that the triangular opening was almost exactly the same height in both. AND.... the gap between the plates is wider with the cam installed in the triangualr opening backwards. That is.... it cannot go together that way. There would be massive force on the plates all the time, if you could even reassemble it.  So, My statement on the matter? The Nismo diff is actually only a 2-way and 1-way. There is no 1.5-way option in it, regardless of what they say. Here's a photo of a real 1.5-way ramp opening from Cusco (along with the 1 way option). And the full set of 1 through 2 way options from their racing diff, which is not same-same as what we'd typically be using, but...the cams work the same. A little blurry, but it comes from this Cusco doc, which is quite helpful. AND.... Cusco do in fact do what I suggested would be sensible, which is to have rings that do 1 and 1.5, and 1.5 and 2. Separately.
