i have the vortech with the 928 impeler upgrade with the 3.13 plley on my car, considering if i want to trade for the powerlab gt35r kit. the shop that will be doing the work told me to go twin turbo or just stick with my supercharger. they said there will be too much turbo lag since the turbo is so big.. i know the powerlab has more potential to make more power up top but is this kit gona have any tq? i couldnt realy find any dyno graph on this kit. anyone that has this kit have any feedback on the driveability of this kit would be great!

 

I love my Vortech...but any turbo kit is going to have more torque than a supercharger...

 

Powerlab search of Google images... first pick, not sure what was done to the motor, but from the looks of it probably stock block on say 7 or 8 psi...

the attached one below is from my car with just the 3.13 pully... i loved it. As for trading the Vortech for the Powerlab kid its all up to what you want to do and what kind of plans you have for the car, if your just going to beat on ppl from light to light in town i would def stick with the supercharger, but if you want big numbers and a HWY monster then go with the Powerlab. I have a firend that has the Powerlab kit on his car and its super smooth and pulls hard, but like you mentioned, its a bit laggy when I compair it to my old supercharger or current TT set ups.

 

thanks for the feedbacks! i feel like my vortech drives like a turbo kit. Not realy any torque and the power kicks in pretty late at round 4000rpm.. i am in the process of buildin my motor, and if i stick with my vortech im definately gonna upgrade to the 2.87 pulley. where does the extra power come in? up top or down low? or just an overall increase in power??

 

i reccomend calling Intense Motorsports, they create powerlab. Or should i say, Powerlab is owned by the same company Highline International.

IMO, im having them build my block and do a stage 2 powerlab right now.. the componenets are all top of the line. theres nothing skimped on, unlike other kits avail. Since you already have the s-charger tho... why not just play w that?

Unless you truly are going to be trading ( not sure why the powerlab guy would do that tho).

 

As described above, they are two completely different kits. I'm going with the Vortech after much deliberation and actually owning a PowerLab kit. If you are going to just DD the car it just depends on what you want more.

 

on a stock block its a complete waste of money to swap setups.

Just keep pulleying your vortech down to reach the trq you want. No different than raisin the boost on the turbo. I was above 350 ft-lbs of trq by 3500 and stayed above that til 6200 rpms. peaked at 400 ft-lbs.

 

For the power that i am making out of my vortech i would only upgrade to a TT kit. A single turbo is not worth it to me.

 

A single turbo would not be worth it to me.
I would only upgrade to a twin kit.

 

^ definitely impressive numbers.

 

Because single turbo setups can't make power?

 

i am building my block,which is why im considering the trade.

 

with a built block and twin turbo, how reliable is our cas??

 

A local 350Z (Saad Racing) recently made 600+ whp with the PowerLab GT35R single turbo kit (1.06 exhaust housing, E85, & stock headers)… seems like a definite upgrade over any VQ supercharger, lol…

 

Might last 10K miles, might last 5.

 

built block.. you will be shorting yourself without a upgraded fuel system.. the clutch will be the limiting factor in my build.. using many if not most of the same parts as the Fortune G35 that layed down 906 to the wheels. Thats w Pro-efi tho... we will be using Uprev.
I will NOT be daily driving like that.. looking for a boost and tune around 450 to the wheels, far more than i need.
The larger turbo comes in between 3k and 3500 im told.. so for daily driving, i like that Ill be out of boost if i keep it light.

Our cars dont pick up until that powerband naturally anyways. I personally like the sound of the power lab versus two smaller turbos JWT etc. Installation and IC piping ease, one extra heat source under the hood, and i believe the ball bearing turbos in the powerlab are fully liquid cooled as well.

Built block? Go for it man.

 

whos building your block? installing the turbo etc. Are you upgrading the fuel system?
Are you upgrading the valves and springs at all?

 

I did not say that...

Because at this point it would be all or nothing for me. Why go single turbo and then later on upgrade again to a twin kit.

 

I'll say it agian and I dont think I can stress it enough, you have to think what you'll be using the car for, DD? Track? HWY monster? that will all play into what you should get. As for were the power and TQ gains will be if you go to a smaller pully I put in the graph of mine on the stock 3.33 the only change for this graph to the 3.13 is the addition on a Utech and 440cc injectors, the gains were pretty substaintial all across the board for power and not really so much in the TQ area, but thats just me. The reason behind not "feeling" the power is because the TQ curve is very flate with the S/C and it pulls all the time, with a turbo your waiting for it to spool before your getting the hit of TQ and power.

You really are making a gamble with how long a built block will last, read some of the trouble that Alberto had with his built motors... some ppl have crappy luck and others have no problems... me personally I some how managed to break a cam on my first go round with a built motor

Theres also a lot of mention that you need more fuel and a better clutch with a built motor, i would assume that you know that already and have plans for that as well. What are your power goals with whatever setup you end up running? that will also play a major role in what you should go with...


S/C Turbo

its all a mater of opinion, i have both and theres up sides to both, i love my S/C Subaru as a daily to just bum around town in, but if i'm out for blood on the HWY the Z is were its at

 

Its easier to replace one turbo though...
