What is every-ones opinions on the past and current skyline engine.I for one regard the VQ35 engine as a much more sophisticated engine and am sure it will be a much more powerful power plant to extract HP from. :(

I think the vq35 engine has a lot more potential to make more power

than the rb26 mainly because the vq35 engine is v6 configuration compared to the inline rb26.

They are making about 1800 hp with the vq35 engine in the states an

thats only in early development stages

You do understand that your point makes absolutely no sense? :P A V-configuration is inferior to a straight configuration: a V is a compromise to try and improve packaging options.

The main reason for "more potential" is in fact the much greater displacement and newer tech.

Stock for stock in a standard Nissan (so excluding the 500hp Z-Tune RB26DETT and the stupidly expensive 450hp VQ35DE that Nismo makes for racing) I'd take the VQ35DE.

Same power (approximately), more torque, smoother power delivery, and probably the same weight (if not lighter, due to its all alloy construction, lower componentry count and more compact design).

If you're talking about a base for modification, the RB is a known quantity. People are still developing the VQ, which hasn't really been used in a performance application for that long.

I just can't get into the V design.. that has been one thing the GTR has always had an inline 6... V12 i can understand.. (imagine a inline 12.. :D )

None the less the VQ is a good engine.. but I still like the RB more.

    • I was under the impression the reason why OEMs are going with solutions like relatively thin "right-sized" cylinder walls with technologies like PTWA and open deck is because they care a lot about whatever marginal knock margin benefits they get from that vs the structural rigidity benefits of a closed deck block and thicker cylinder walls. I also see some weird stuff like plastic inserts in the water jacket around the cylinders to try and equalize cylinder wall temperatures. re: the PRP blocks and heads at the end of the day it's hard to know what is and isn't going to work there, just have to see what the initial buyers say about it.
    • Which is why I didn't mention that hardness testing, and specifically mentioned the bore and deck thickness testing. Yeah, not really. The bore temperature will be a lot more even around the top half inch or so, where the material distribution is dominated by the deck, and which is the only place where the bore surface temperature heating any gas in the cylinder is likely to have any effect on detonation. Think about it. Another inch or so down the bore, you might have a hotter spot. The gas there might get a bit hotter, then the piston rises squeezes that gas away from there at high speed and mixes it with other gas from nearby. Instant dilution of the problem. I'd be surprised if it was an issue at any time other than in racing engines or OEM dev engines being run at the ragged edge of tuning. Say what now?
    • https://dsportmag.com/the-tech/education/engine-tech-material-hardness-testing/ The PRP testing on block hardness I'm not sure how much it actually can be trusted. The thinner cylinder walls on RBs is a bit of a problem vs 2JZ but it really depends on the design goal. Siamesed cylinder bores like a 2JZ cause uneven cylinder wall temps too, which means a bit of distortion induced by that + the hotspot can affect knock margin. Something that actually gives me a bit of pause with the PRP block, whether super thick cylinder walls are going to keep it from being drop-in compatible on an otherwise OEM rebuild. 
    • Yeah very valid point. I am waiting for one of the other tuners to come back from vacation so he can help me a bit when the cat is installed again. In the meantime I am going to finish up my polishing and ceramic coating that I have started myself.    N45 Dr Beasley product is highly recommended for a paint primer / polisher. Using this EXO Gtechniq also for the ceramic but next time might use the light serum before hand also. Looks great. 
    • Running rich in conditions where it shouldn't probably won't do great things for catalytic converter lifespan. I would fix that sooner than later.
