Hey. There was a person at the auto salons that Supercharged his Skyline. Its a waste of money. He spend soo much money putting in a supercharger and got the power of a stock Gts-t (140Kw). Might as well just buy a stock GTs-t, will be quicker and cheaper.

As a very general rule of thumb, supercharging is good for down low, but useless up high (and turbos are the reverse).

Basically there is no particularly good reason to supercharge a Skyline, in fact many would argue its an inferior technology (including the man who designed the supercharged-6 used in Holden's Commodore).

Before making your mind up read these threads:




Look for warpspeed's posts, he has some opinions and (more importantly) experiences that are vastly different to those expressed above.

from what I have seen and read the older type of blowers on the old V8s and stuff, the roots and screw type are pretty inefficient. But the the more modern centrifigal type ( vortech ) are a lot lot better in design. Very similar to a turbo in fact. They drain a lot less from the crank to operate as well.

As an example my friend supercharged his 3.2l V6 rodeo. When stock it had 76rwkw. They strapped a vortech V1-s trim @ 10psi to it. It hit 200rwkw at 6500rpm and the curve was still climbing hard but they backed off because the engine would have let go if revved any harder. This gave him incentive to do a full engine rebuild. He upgraded to the T-Trim and its now making 385rwkw @ 25psi and they havent sorted out a few little gremlins that are keeping it from 400. The drivers and the cars maiden 400m pass yielded an 11.9 sec pass on slicks that had not been warmed up properley.

i went to a place near me to get a quote on supercharging my r33 gts, for a custom setup including front mount and all the shit they wanted $12,000 Hahahahahaha

he said it would have made 200 rwkw (currently 107rwkw)

but that isnt an option as selling my car plus that 12 grand (so all up about $24-26,000)

that would get me a besat of a gts-t.

before i went in there i thaught that it would cost like 5-6000 to do it.

300rwkw isn't cheap.

Unless most or some of the mods are already there to support it.

To get 300rwkw in a GTST from dead stock you are looking at a minimum of $7000-8000.

Because I've built another motor its more in the vicinity of almost 15k. :rofl:

But ahh well its all for my enjoyment.

When My other half says 'Your not going to get your money back'

I say.. 'I'm not doing it to get my money back.'


I looked in to it for my VS 5ltr Commodore before I sold it.

It was going to cost around 7-8k to get only just over 200rwkw.

I was told that to get more power from there I was going to have to start opening up the engine + a different trim etc.

It is expensive to do it properly.

Also, considering supercharged skylines arn't exactly common, the workshop would pretty much need to do all R&D work as well.

There is a big difference in labour between fitting bolt on parts and having stuff custom built for an uncommon application.

Also, depending on what was included in the $12k it might not be that bad (think management & tuning, exhaust, IC, labour etc).

Given a choice of spending $3000 or more on the car, why not go for the tried end proven method. I know that for that muchmoney I can get a stock GTSt to 250ish rwkw, but when it comes to superchargers its a lot more of an unknown.

There is nothing wrong with walking the less troden path, but be prepared to pay the $

    • I dunno. My fuel pressure gauge is a handheld WIKA 6bar 4" dial with a couple of lengths of fuel hose and a T piece. I just install it when I need to know. On any car where I need to know.
    • My 2016 Q50 does have a crossover, and it is a twin 45mm (out diameter) system, so not exactly free flowing. Just take the car to Castle Hill Exhaust (or any other decent performance exhaust shop) and get it on a hoist for them to check out, based on power targets they will make something custom for you.
    • Playing devil's advocate, upping the fuel pump severely while using stock gear can actually raise the fuel pressure because it overpowers the reg. The thing is, to really confirm this, you install a FPR gauge, and usually that also comes with a regulator.... so nobody knows whether this actually is overpowering the stock regulator or not. Suppose that scenario is not a stock car tho.
    • A chaser is really just a tap. Just a less aggressive tap. It still has to be able to move metal to do its job. It may not cut the way a tap does, but it still has to push deformed threads around, and deformed threads are often a hair's breadth away from snapping off. Especially in cast aluminium alloys.
    • I visually inspected the threads and they look intact and not so dirty, so I don’t understand why they wouldn’t thread in straight.    How would a chaser cause any damage? It’s intended to clean up the threads right? Even if it was cross threaded. That shouldn’t be the case though because the studs that were removed were OEM. The intake side had no issue.
