yeah made up.. because the engine is in a american spec nissan z33 350z, i can get some big dumps made for it... and it will be pretty cheap here, about the same price as importing a set.

what you think ?

your setup sounds like fun - maybe run the oem airbox & see how the sound changes? i'd also say its the pods that are making the noise...

ive also wondered whether i should upgrade my hks split dump pipes to the bellmouth type / 3 inch dumps if im aiming for 350awkw with a 2.6ltr & -5s? any thoughts?

i am only running 16psi of boost atm... its summer here and even at 2am its 40deg c....

also i am running stock r32 gtr dump pipes because the hks dumps i had on the 2510 did not fit for some reason.

how much power would these stock r32 gtr dump pipes be robbing from my setup? i was thinking of getting some replacements or get some bad ass 3" ones made, what would be better?? or is it not needed? come winter i really do want around 340rwkw

-9 on an RB30..its very responsive like a NA.

Sounds like a pretty lethal setup. Add e85 to the mix and you should

be well above 340rwkw in the winter. Some people have hit around 370rwkw on e85

on a standard 26 with -9s. Power figure yet to be backed up with 1/4 run though.

Ditch the 32 dumps for some 34 dumps. 55mm outlet compared to a 59mm outlet

on 33 dumps but you can see the inlet of the 34 dumps promote flow that is more laminar.

That and its quite a bit bigger in the middle as well.

Keen to see how this turns out for you

we dont have e85 here, but our 98 is good, real good... 330 - 340kw on 98 will do me just fine.

i am going to get a set of r34 dumps i think.

I'm using HPI dumps with my -9s and making 350kw on 98

So when winter hits in sure you can get there aslong as the rest of the exhaust is up for it

front pipes measure 61mm & collector is 88mm - is there an advantage to running larger diameter dump pipes if my front pipes are this size?

my current hks split dump pipes are 59mm

What size are your front pipes, Marko?

thats what she said hey Paul :)

makes me wonder how much of a restriction my rb30dett was when i had it - that also ran hks split dumps with only a 3.2" inch system & slightly smaller front pipes.

what size front pipes u running big boy?

Jesus, they're tiny!!!

I'd say not, unless you're gonna change front pipes too.

far out that r they straight pipes then (no cat)?

I thought u said 3.5" was your old cat back exhaust

Two mufflers, no cats, twin tips... Almost looks standard...

May have, but I've had this system on for close to two years.

    • @GTSBoy This method was able to get readings of -10 to -2, so it looks like its monitoring.  Now I need to figure out why the vacuum on the line provided isn't alternating with manifold pressure.  I went with 2 lines that an RB25 tuner recommended but I'll get a longer hose and try directly off the back of the manifold.  He may have been used to OEM intake setups while I have a DBW setup that removed the MAF and IACV.  
    • I work at a car detailing and tinting shop called Quark which gets all manner of German cars in usually (mainly due to a contract with Mercedes Benz Kita Osaka, BMW Nishinomiya and others) but every once in a while something special comes in, like a fully restored 1972 HS30 Nissan Fairlady 240ZG... The shop owner had immediately started applying film to the windows as soon as it was in the shop so the interior was completely covered in towels and plastic sheets. But I could get a few photos of the engine bay which was restored like new. Such an amazing car to see in pristine condition in Japan these days.  
    • Was going to say the car pulls up nicely everywhere, especially going into that last long right hander before the main straight. Looks like a lot of fun.
    • Hey Dave, welcome aboard! Good to see another soon-to-be Stagea owner here. The wagons are awesome — plenty of space, still got that Skyline DNA, and loads of potential if you’re into mods. Definitely post up pics when you get it, everyone here loves seeing new builds. What model/year are you looking at?
