The HKS is better than VORTECH ?
my Z will be upgrade with this parts:
HKS ROTREX Supercharger
ECU reprog
6 additional injector
fuel pump of VQ40
headers maxim works
Y pipe + exhaust AMUSE R1 TITAN
High flow cats SARD
wheels TE 37 time attack edition 2006 (19" 10,5 rear, 19" 9,5 front)
suspension TEIN Monoflex with EDFC
big brake kit AP Racing (6pot front and 4 rear)
ARC Strut BAR
ARC oil tank
GT SPEC under brace etc...
NISMO clutch and flywheel
etc...

I hope 400hp with this upgrade, do you think is possible ?

thank you for your reply

u might get 400hp to the crank with the HKS but u can for sure get 400hp to the wheel from the vortech by getting a smaller pulley.

 

Vortech is MUCH better power for the money, as long as they've fixed a few of the manufacturing issues we've seen lately.

 

What kind of tech support and tuners do you have in france? that would sway me in a big way regardless of the power.

 

I like the HKS unit myself. not as noisy, good low end power and if I remember, ninja was putting out over 400whp with his HKS setup so it is possible.

 

I would estimate with your mods you may see around 340RWhp an 325RwTq with the HKS.

Now the Votech as taurran stated.
With a Vorech you could easily get 400RWhp an 338RWtq. Just change the pulley.
I myself am wating to see more on the HKS GT Supercharger Pro kit. I have talked with HKS USA an gotten info on the unit.

The number I was quoted on there test car with there Cams an EMS unit was 450 Rwhp and 385tq. This was with a 10lb pully.

Salut la france!
go with the vortech...

 

i guess 400 to the wheels is very optimistic even with a vortech
i say 400 to the crank with the 2.87 pulley...

 

Think he gave it a spray of NO2 to the intercooler that got sucked into the intake to get it there . Think he was around 365whp [dynoJet] with SC alone

 

thanks for your reply
my tuner is not in france, but in belgium he's owner of nissan garage.
he don't use all part of HKS kits, and modify some parts, he use HKS because he incorporate enclosing lubrification and use planetary rollers.
he said to me be sur to have 380/400 hp to the wheels.
a friend of mine use vortech and have little problem with them

 

why not get the new hks gt-supercharger? I believe it should be available in Europe? Otherwise, I'd go with the vortech. bonne chance!

 

Really? I've never heard of an HKS unit making this kind of power.

The most feedback I've heard from the few Central Florida HKS ROTREX owners is "wasted my money, shoulda gone turbo". It's good if you want a name brand kit with good build quality, but for $/hp the vortech seems to make people much happier.

 

Vortech with 2.87 pulley can go way past 400 rwhp if you have the right supporting mods & an aggressive tune.

^ u have a vortech on ur z ?

 

i believe he does.

 

Actually he doesn't. skaterbasist is a G owner with aspirations of also being a Vortech'd G owner in he future.

 

ahh, i actually got him confused with you hexx, he uses the same avatar.

 

Oh yeah. I never noticed that before. haha!

 

No I don't have vortech on my car, but friend of mine yes
he exist a new supercharger HKS?
my tuner is sure, he said to me two days ago, 380/400 hp ....
so I will see that on january at the end of the upgrade with dyno run
ad tell you what

 

yes hks has developed a new supercharger that is superior to the rotrex. Check the hks japan website for more info.
