G'day guys.

Just wondering who on here is running a 26/30 in thier car, what bottom end and bolt ons you have and what power you are producing.

Just curious because I'm currently building one for my vl street/drag car, I'm looking for mid 9s.

I'm also undecided on which turbo to use, my choices are a 1000hp plain bearing ta45 76wheel and .91 rear ot a 1.00 rear t04z.

Also, I'm unsure on how far to go with the head, springs, valves etc and also cam specs.

I want something that is going to run the times at the track, whilst not being too laggy for street use.

I have a very tough jatco auto behind her which is going to sap the power a bit but it will make up for it with times.

So far my setup consists of...

26 head and standard plenum

cp forged pistons

forged rods

nitrided crank

grub screwed

o-ringed

etc

rochester 1000cc injectors

eXtm custom exhaust manifold

turbosmart 45mm gate

3.5" from turbo back

I'm also undecided on an ECU, can anyone help me there?

With this setup and say the 1.00 t04z would it be unrealistic to expect 450-500rwhp on around 24psi and pump fuel with a good head and set of cams?

What setup are you guys using on the 26/30 and what sourt of power is it producing?

cheers

So do you have questions or do you want comparisons?

Because all you did was ask for results, and they are in the sticky :/

There arent a lot of users on here with a 26/30. And those that have *most* have posted up in the sticky thread.

Also, checking the RB26 dyno sticky will help aswell.

A few people are using T04Z's and have posted up, so obviously a bit of lateral thought application and you can come up with some expected results & parts listed

yeah i just wanted to know, what size cams i should be using and how far to go with the head, also it looks like ill be using the t04z with 1.00 rear so I want to know how far i have to go with the head to make 450-500rwhp comfortably on pump fuel

I think you would be far better off running a GT3582R at that power level , even then your not really stressing the thing . Running a larger turbo than necessary for a set power level merely lifts the on boost power range upwards . You would expect the boost enhanced torque to be happening under 3500 rpm even with the 1.06 A/R GT35 turbine housing .

Cheers A .

    • Pressure when IDLING, is meant to be 51PSi... So that amperage value needs to go up a fair chunk... I'd personally be factoring for more like 12amp at least on those runs, and at that point you need to hope the already there wiring doesn't drop you a volt or two, as that's a lot of fuel pressure flow drop off from 13.5 to 12V! Taking idle pressure of 51psi, means the pump will be drawing a MINIMUM of 9amps all the time based on your reading of the graph (3bar base, then allowing an extra 0.5bar for boost = roughly 51psi)
    • Hi all,  I am in the market for an R200 longnose diff out of a Z31 300ZX, or S12 RSX, DR30 skyline, or similar, in a 3.9 ratio.  Preferably a late model one with the M12 crownwheel bolts.  The only easy to find advert for one of these was my ad back in 2007 when I sold it on this forum.  I sold the diff as I had sold the car it goes to, but as it turns out, after 18 years I got the car back late last year, so now I'm looking for the diff !  If anyone knows where to find a longnose R200 LSD with the M12 crownwheel bolts, drop me a line at [email protected] - Bonus paid if soomeone comes up with the original diff (stranger things have happened !).  Cheers   Ben D    
    • Hi everyone, I used to post here a bit from 2004-2013, when I owned various Nissans, in particular my S12 RSX gazelle, which was sold in 2007.  As luck would have it, after an 18 year hiatus, the car found its way back to me last year, and over the past 11 months I have had the pleasure of restoring it with my kids.  One thing that I am after in particular is a 3.9 ratio R200 LSD for it.  I actually sold the one out of the car here back in 2007 , and it would be incredible if I could track down who I sold it to, so I can see how they have progressed over the years (and to be honest, to see whether I can get the diff back !).  Anyways, hi all and let me know "where are the R200 Longnose diffs all at these days ?  Cheers Ben D  
    • Arms will be the same as the G35 or 350Z, but as above, there was a change in the lower control arm where it connects to the ball joint.  That said, you can remove the ball joint cone from your old ball joints and fit them to the new ball joints.  To be honest, I didn't think the ball joints themselves were different. The main ball joint is a bit awkward to replace, you really need to remove the steering knuckle to press out the old one.  Some people have used tools to remove it in place, but it just seemed too hard to get to. If you are going to press out/in that ball joint, then you may as well just replace the bushings in the LCA and the compression rod.  You can buy the compression rod bushing from Nissan, but the LCA bushes, you will need to go aftermarket. Much cheaper than buying the whole arm.
    • Ha, well, it's been.... a bit of a journey. Things have taken much longer than I'd hoped. I'll probably put up a thread at some stage. Hopefully soon. The car's not done any kms since my update in June though, put it that way.
