Oh and you should really be asking your engine builder what head work, as they will be creating and designing the setup.

What have they said thus far?

Rwkw pffft lol

yeah i know!

But it is my power goal!

A couple of years ago i chased the magic 500hp and got there in my old v8 lexus i built with my paps!

Now im going the 500awkw

obviously power is not all! A well balanced chassis n highly tuned suspension will all come into play as the car progresses!

I basically wanna do a 9 have full street trim n a/c and a h pattern box! But still try to make the engine bay not look like theres 30+ grand spent on it!

i have asked n we have been through it!

But im a pain in the ass n wanna know what the sau community would do!

Isnt that half the reason the forums here!

Without a fkn paragrapgh of parts

cams, valves, springs, machining etc!

Its listed a few posts back

he told me 2871s are lag monsters but they would do the job but i wont like em lol

I live in NZ where anything goes so long as it is done properly and certed but if you are so constricted by your local laws have you considered making your car a track only so you can do what is best rather than what is legal? Sounds like you have another daily driver so get a trailer and go to town on your Skyline!

Get a single Borg Warner S400SX with 67mm compressor wheel. Get the head ported by someone who knows what they're doing then give all the information to Kelford for them to make you a custom grind.

[zebra]

Get a single Borg Warner EFR 9081.

If you do do single, have a look at the Presicion 7175

[bigmikespec]

Bargghh... if you are into marketing hype get one! You can't trust a striped horse

[Piggaz]

Well the OP wanted 500kw, you going to say the -5s will get 500kw? Are you saying with a pair of HKS GT-RS combined with a RB30, the OP won't have useable power? It all depends on his build and supporting modifications. You're providing misleading information. Read his first post.

Back to back comparisons, what? from GT-RS > 2530s? Running a bigger turbo which their engine was not built for? Piggaz was running a head which wasn't even ported, slapped on with 270 10.25mm. The only experience they have had is downsizing their turbo to make the full efficiency of their engine/turbo combination.

Whereas someone who has had experience with 2530s and has built their motor to suit the HKS GT-RS? Who has no surge at all? Whereas those guys complaining about their surge and how it is a shit turbo etc are making less power than someone in a 2.6? What no explaination for this? You obviously don't know what you're talking about with your 365kw.

As i said earlier, Piggaz motor can't handle the GT-RS even if it was stroked because his cylinder head was not made to suit the application. If done right, it would've blew his mind away. Yet he made under 450rwkw? So he might as well go back and use -5s and achieve the same power because his car wasnt made for 450+ otherwise he would have got it.

I like how you seem to know more about my cylinder head than myself seeing that its now a "standard head".

Ring up Yavuz now and he said himself the night we were tuning "450 is just a intake cam twist away" and that was with baby 5's. We were going to go for a 'hero run' but for what? Satisfy some bloke on SAU?

Look at Racepace and their king dick engine that is 1.5 seconds slower around Winton than a V8 supercar. Makes more power than your's on 20 psi on 98 with a curve to die for with 449 kw. But I spose that setup is crap too because it didn't crack 450?

Gav made 462 rwkw.

Ryan 1200 is at 440 with 2530's.

But hang on.......

As i said, the car was laggy if i am driving through the streets around on 2nd gear but if you drove from 1st and kept in on power. Was a monster!

What sort of "GUN" setup needs to be driven in 1st to make the car move

To the OP. After seeing the results on N1GTR's car with a DIRECT COMPARISON (ONLY thing changed was the turbo's) between the high and almighty RS's and 5's there is no comparison. It's comical and just downright rude! I will not be posting the graph as it is not mine to post.

This discussion and argument has been had many times. It just goes round and round in circles. There is a reason why the 'circuit' guys got rid of the RS's... that thing called area under the curve.

Which curve would you rather? Since went onto make 620 HP at the treads.

"Oh but 5's have no top end". Yep

The ONLY result that I have seen over the years that has been awsome with the RS's was Diemar's. He said himself that you need a huge dollar head to get them to work properly and that's something that most guys wont do.

[zebra]

That above graph sums up perfectly why -5 cars will still be quicker at the strip than the RS'

All the antilag/launch control in the world wont keep the tyres or clutch slipping to keep the engine at 8000rpm unless you have 1000+hp, the revs will drop back and it will fall off boost

The other thing the graphs wont show is how long the RS's will take to come back on between gearshifts, Piggaz's car is near on instant, infact it was better than my old car, which I felt was about as instant as a turbo could possibly be.

Ive been in a RS powered GTR once, and I was counting the seconds for boost to come between gearshifts, it reminded my of a mates GTR that had a T88-38gk on it, but without the 1000hp hit up top

another mate had a 300zx with 2540's (near enough the same as RS') it was also laggy, and it had mega $$$ heads and manifolds on it, it was slower round QR than 300zx's with standard turbos and more weight

I didn't say it was responsive, hence the change to RB30 to improve response

What the whole point of this thread is that those who are saying the HKS GT-RS are shit compared to the -5s are misleading those whom are asking.

For those whois motor, such as Piggaz wasn't built for it are saying that the turbo is shit. Is incorrect. It is his motor which is shit and can't handle the GT-RS.

[destrukshn]

Pointless argument going back and fourths, in the end, just trying to give others insight in to what is being said is not necessarily right.

If you want to run -5s, -10s if you're happy with your car then so be it. If it works then leave it if not change it, simple

[R31Nismoid]

That was the engine dyno results, no airbox/intake piping, drivetrain etc.

Would be back under 500rwkw you'd think once in the car. Hard to say as no results got posted after that far as i know (be awesome if they were handy to see once incar).

So tell me why im a measly15 kw behind you on smaller turbo's on less boost..?

2.0 bar trailing back to 24 psi

im at 24 trailing back to 22?

so ur saying GT-RS wont be shit yet you havn't even finished the motor yet to see, but ur happy to disregard anything from piggaz's car and the MANY MANY OTHERS who have said that they are outdated crap ranging from 2.6-3L.. Face it turbo technology has come forward alot and they are just outdated, Spending 15K on king dick headwork to match outdated turbos is like shaving your balls with a piece of bark and is not cost effective or smart.. You pick turbos to suit your motor not vice versa

Get off the forums and get out into one of these cars and see for yourself how much better they are.. I of course know you wont do this as its too much effort and would much rather munch ur gearbox throwing it back to 1st to get some boost.. Although it might just be your boost controller, I hear you have alot of trouble setting it up and need someone else to do it for you..

sorry buddy you lose this argument and will only make yourself horribly unpopular and disliked trying to argue your point.. I could write more but cbf arguing with narrow minded people

From my last run, i can tell you it wouldnt be only 15kw

Yeah i am tired of wasting my time arguing my point to those who are narrow minded only to the -5s as well. We'll just leave it there.

Lol at outdated... I am embarrassed for you, and $15k, you are getting ripped
