Achieving 600 RWHP

NIZZING · 05-09-2011, 02:41 PM

Hey everyone,

Well I have posted similar threads before but am hearing mixed things from everyone I talk to. My goal is to try and get the most out of my Stage 2 GTM tt kit without causing any future problems.

The parts so far I have coming in are...

GTM stage 2 tt kit
Os giken twin disc clutch
34 row oil cooler

I already Greddy ti-c exhaust so i dont need that.

So what is left to do to acieve the 600-650 whp daily driven..

What needs to be done to the motor?

thanks

To do so reliably you might want to build the block, im not sure of anyone on here who has one to that power level and DD'd it...

The thing to remember is to play you have to pay.

i doubt u can reach that and stay in the safe side for along period of time , so its better to be safe than sorry , 500 to 550whp is the most famous numbers around from my small knowldge .

650whp and daily driver really can't be used in the same sentence...

it might be your daily driver, but it wont last very long, OR you'll spend thousands in repairs.

3" down pipes
Cooling - will not know what else until you probably finish and see what is being pushed (radiator, power steering, etc.)
System monitor/control - HKS camp, boost controller, etc.
Built motor - you may not have to go crazy here but certain parts are going to need to be upgraded
Tune - This here will make or break you being able to daily drive the car

Built motor and cooling mods in every aspect. Maybe even a dual fuel pump setup also. More than 500 WHP is a waste IMO.

No doubt, 600-650 HP on a stock block is asking for future problems, and probably in the not too distant future. I would recommend a new radiator, built bottom end, and return fuel system at a minimum in addition to what you have listed.

Even with the above, you always need to be prepared for potential issues on a car putting down twice the factory HP. Things break (axles, diffs, trans, etc.) when you start to do that. You really should have a second car, or you will regret it later. Not trying to talk you out of it as many people have done similar builds on Z's in the past, but it sounds like you need a better idea of what you are getting into.

You can get by with a single fuel pump (check out the new Deatchworks pump), but you also need to consider a better form of EMS than an UpRev tune with that kind of power (HKS, Haltech, etc.) and full set of gauges (wideband A/F, boost, oil temp, oil pressure, fuel pressure at a minimum).

At this point you ordered the wrong turbos if you want a constant 650whp. They are pretty much maxed out not too much after the 600whp mark. Also your fuel system is maxed out at around 600whp. I would just be happy with 560whp and stg2 and go on with life. Daily driven at those power levels I would say new pistons and rods. A short block is not needed to get there, though I would recommend it for daily driven z's.

The cheaper option is to get a boost controller and daily drive the car at a lower PSI levels and boost up to 12psi with a push of a button when you want 560+ hp. This will save you from needing a built block for a long time. You paid for the stock internals, might as well get some use out of them.

Here is a G37 with stage 2 turbos, 3" down pipes with external WG's and 3" exhaust. Check out the link below. He is making 611whp on 100 oct fuel.

Lol, but you are right on the Z platform for sure. I honestly think that if you want 650+ at the wheels, switching platforms makes the most sense.

Yes, let me change the power goals. 550-600 whp is plenty for what I am looking for. I really just want to be able to get the most out of my stage 2 kit while not pushing it to its very limits.

Do you need this power everyday?
I agree with JB, get a good boost controller and run a lower amount of boost daily and when you want more then turn the knob up.

SPOHN · 05-09-2011, 07:51 PM

Think about tires also. You will eat threw them fast. Fast car needs good brakes also.

What happen to the OP anyways?

What are you looking for this power to do for you & where? Is this for the Track/Street/personal cocktail brag numbers?

400-500 has been solid bolt on power on an HR motor so I'm sure that 450-550 should be cake on a VHR motor. That's along with the supporting mods.

JB-370z · 05-09-2011, 08:06 PM

You can turn the boost all the way down as far as what the stock boost spring is. So if you have a 6psi spring then you can turn your boost all the way down to 6psi, no lower. So driving on the daily at 440-460whp but when that Vett or Porsche pulls up, BAM! hit the boost!

This kid is going to blow the motor up or kill himself smh.
