Which rods and pistons for N/A engine?

Also, does UTEC support VTC tunning?

I've also heard that higher CR may increase the efficiency of the engine, raising the fuel economy.
And finally, I have an old issue of Option with the Esprit 11.5:1 CR kit and cams, and they are making like 360 horses. High CR + good cams + high revs = as much power as a turbo at ~6psi.

Also, a turbo at 6psi would put down 360rwhp. The Esprit engine is 360 crank.

Let hope they do as this would really benefit motors with big cams, allowing them to retain low end torque and pass emissions tests when combined with the Nismo VTC pulleys.
Do you guys need to get the car checked out every year up there in NSW?

No but I believe its possible for Police to do a quick test and they defect you until you get a proper test done and pass. If that happens you could always swap the heads to some with normal cams in them, go do the test, then throw the other heads back on. Also sometimes I believe you need an emissions test if your getting an engine transplant engineered, not sure if this is the same for engine mods being engineered.
Ive never been tested or seen anyone be tested but my mate has so it can happen. Cams are the one mod that will make you fail an emissions test but with VTC this should be different as it can allow you to recycle the exhaust gases, like a EGR valve, for cleaner emissions.

Police normally will not carry out test on the engine unless the engine bay looks/sounds like a lot of works have been done to it... with the works that you are going to do, I think the engine will still idle, sound and look like a stock one as well...
Vic police normally doesn't do that type of test... at least I have not heard anyone got that problem... the most common problems are the exposed filters under the bonnet, loud exhaust and the ride height issues down here...

I would go with Arias pistons (we can order custom bore, custom CR, and custom coating if you want it ready straight from Arias) and Carrillo A-Beam connecting rods.
Let me know if you need either of these parts, Richie.

That's the video I am referring to. I see now the link of the video is to a GTO video.

Hey Richie, our Extreme Duty Arias design is going to be a few grams heavier than standard duty, and you have to run slightly larger piston to wall clearances. I have run and tune engines with this piston design, and I am happy to report that there is no meaningful increase in engine noise, piston slap, etc. As Brandon mentioned, we can have them made in any CR, with coatings, if you like (I like Moly coatings), and any bore size.

Posting pictures of Carrillo A-Beam rods that I have got... they are so light and looks very strong and promising too!!! It will be good for my N/A rebuild I would say...
Thank you guys... I've decided to leave the piston design to Simon at Nizpro (www.nizpro.com.au) who is doing the engine rebuild for me this time for the warranty purpose (he is going to get a set made locally)... I know that we have decided to go for 11.5:1 and the valve cuts on the pistons will be slightly deeper than stock (just in case that I might want to run higher lift than 11mm cams later, so don't need to get the engine out again)...
Will keep you guys posted!

richie

Nismo 350z
I am not too sure though... but it should be somewhere around 255KW = 346HP at the engine... because I gained around 52rwKW = 70rwHP with my current setup... so the figure should be conservative here...
I am not aiming for heaps with high CR pistons, want a stronger bottom end to rev up now.
Murray:
When are you going to rebuild the engine? I guess I will only do it after you have yours done though... scheduled for 9th of Jan next year...
cheers,
richie

HolyC... they are beautiful mate! Good on ya!!! Love those pistons!
btw, do you know what's the diff between A-beam and I-beam? Thanks!

Now I know why Sharif is always saying sometimes they just look too pretty to put in the engine! Those pics are great!

Hey...I think I recognize these items. I am glad they made it safely across the pacific. Enjoy!
This is the first set of "higher" compression pistons I have had Arias make for me. They are 10.0:1 and also the Extreme Duty design. Notice the valve relief machining, and the fine detail on the crown.
