Building An Rb26 For Response....

[Nismo 3.2ish]

There is, well not so much before and after more just different setups and their result in the Forced Performance Thread home page at the top there are dyno result threads

http://www.skylinesaustralia.com/forums/topic/104332-rb30-hybrid-upgrade-all-dyno-results/

http://www.skylinesaustralia.com/forums/topic/93880-rb26-turbo-upgrade-all-dyno-results/

This are the two most relevant for you

Thanks Mick I will have a look when I get home.

Took Scottys advice and started a new post for Strokers and see what happens

[Nismo 3.2ish]

How long does it take for a new thread to be OKed?

[Piggaz]

Is it in the projects section? If it is, a couple days sometimes.

[The real NISMO1]

Sorry I have some private posts but I cannot open anything private on my laptop under Nismo1 ?? bloody laptop

But I can open threads and posts?

[Wongy]

Haha, car is slowly getting there, nothing new from last dyno results, got myself some nismo AFM, and about to purchase a set of new o2 sensors, and recently acquired a ARC cooling panel too, nothing fancy pants in power division lately xD and maybe looking at getting hard pipe kit soon,and helping dad with his 32gtr

[nick_7g]

So did the tuner say the 312kw was what he expected from the -5's?

[Wongy]

Tbh, he said he was expecting around that because of the restrictions of my standard AFMs, so yea....when i install my next parts gonna go different tuner, my last tune was at JEM, and might see what other people suggest to go, when i'm ready that is xD colelct more parts first, hehe.

[XKLABA]

The standard AFM and the Nismo are the same dimensions so if the restriction is flow the Nismos won't help you, you will need Z32s

[Wongy]

The NISMO RB26DETT Engine Parts - Air Flow Meter is a direct, easy and a popular upgrade on RB26DETT engines as they are the same dimensions as the stock units. This is a popular and necessary upgrade for engines making serious HP! You will need 2 in order to replace your MAF system. These NISMO units can flow a max of 2400kg/h of air and support 775ps max power whereas the stock ones can only flow 1400kg/h of air and support 450ps max power.

Taken from RHDjapan xD

[XKLABA]

Nice cut and post but I already know about them

So in the same sentence they say they are the same dimensions as stock but can flow nearly twice the amount of air

Just saying they are both 65mm AFMs so IF air flow is a restriction then replacing it with another 65mm AFM isn't really going to help you, if its tuning resolution that is restricting and NOT flow then sure go for the Nismos, they only twice the price as Z32s and flow less

Edit: and with less tuning resolution

[Wongy]

ahh, thanks for the info, so did i just waste money buying NISMO ones then? o_0 but as people said before, air restriction shouldn't be an issue as in previous posts people have said that my OEM AFM should be fine even if i've changed turbos and the mods i have now o_0 so now i'm abit worried as to if there's something else wrong with my engine or it was just the tune =\

Tuners are usually suspect of old engines and unknown builds. They don't always trust a setup to lean on them hard, especially the first time they tune them. They don't want to blow your engine, it makes them look bad.

Sometimes all it takes is fitting an exhaust temp gauge, or telling them you have a spare engine to go in, that way they aren't so scared to turn up the wick. E85 should take most of their worries away.

[Wongy]

Haha, not keen on going e85 though so pretty much say push it hard? Haha

If the workshop and tuner is worth half a grain of salt, they will have a scope to checkout the pistons if they are forged and a good set of knock sensors to read whats happening while tuning.

If they see stock pistons they should know what time of day it is.....

Hi , It is Pete , I am away from my PC and cannot answer as TT350GT.

I have asked Jim to quote on the Quaife diff and we will go from there.

Just drove up the coast to Port Macquarie , great day for a drive and even with the last mods it was fun.

Lucky though , as I stick to the speed limit but the bloke in front got knocked off for 20 over , lucky me

why would they go looking for forged pistons? tuners aren't going to waste time doing that......they don't need to if they have the right tools to tune the car properly.

Because thats what professional workshops do when a unknown engine rolls up and the customer asks for a zillion Kw.

They pull the plugs, get a bore scope out and checkout the condition and whats inside.

Without knowing if the bottom end is built, would you lay into it?

Knock sensors can only tell you so much, a pulled ring land can happen without much knock on a stock piston.

hmm i just think i'd never expect a tuner to do these things....after all you take a car to a tuner to set the tune for your modifications...if you don't even know what those modifications are then you can be wasting your time...but in the same token the tuner doesn't need to know when tuning because he/she will find the limitations with the tools they use. e.g knock limited engine. Most of the time tuners usually end up telling customers to go and buy/replace stuff that they find is the restriction limiting there performance potential....hence probably why he suggested the AFM's in this case.

[WMDC35]

Most tuners round these ways will tune it based on the info given, if there's unknowns they'll usually recommend on the cautious side, but will push it if requested & the waiver is signed

[Ben C34]

There's a big difference between tuning a car making 200rwkw and 400rwkw

I would expect the tuner if they want to maintain a professional image would approach things differently.

And keep in mind the tuner isn't actually wasting their time. They get paid for their time.
