thinking of a turbo setup

Boosted Performance

Mike, you are comparing my stock block 04 DE dyno to a 370z dyno (because no DE has ever made 276whp on a base run) Not sure the boost on that run either. Thre is almost a 10 year time laps between these two engines.

I also think that install cost should be thrown in the mix as well, not to mention ease of maintenance. It is not just a $500 difference, and I am sure many would agree.

It would be silly to get in to an argument over the two systems, as they are very different, and each have pros and cons.

EDIT:

I think this would be a much better comparison, as the engines are the same and boost is the same:

91 Octane fuel, 9 PSI, with a temp. manual boost controller:


Specs on the build aboove:

GTM Stage 2 Turn-Key Twin Turbo System
Cosworth Intake Manifold
Cosworth fuel rails
600cc injectors
GTM ECU Flash
Upgraded MAF Sensor
GTM 14" Fan kit w/ fan controller
GReddy EVO TT Exhaust
S.S. Braided vacuum lines
GTM 3" Down pipes
Defi Gauges

Credit the Cossworth IM for carrying the power better in the upper RPM's.

Mike@GTM

Of course it's silly to compare a 350Z DE to a 370Z...I was quoting your post with the DE engine. Why you would have brought up a DE motor on a VHR forum is beyond me.

Ultimately, you are right...there is no comparison between a single turbo kit and a twin turbo kit. TT wins all day long.

Mike@GTM

Thank you for proving my point even more with your edit and our own graph from another forum. The TT kit is at 375ft-lbs of torque at 3500rpm...the same amount of torque as the single turbo was producing on the graph you supplied. Then the TT just continues to walk away from the single all the way to redline whereas the single falls on its face at 6k rpm. That sir, is area under the curve. Thank you.

Boosted Performance

Ya, boost spikes tend to do that.. It falls right back to 375ft/tq at 4200rpm. I can read a dyno graph.

Look at the first (6psi) dyno in that build thread.

Anyway, there is no point to this. The customers can decide which kit better suites them, and the budget they have to work with. Both are quality kits, and capable of making more power than 98% of the guys driving these cars will ever use.

Mike@GTM

...and then sweeps back up over 400ft-lbs by 5k. Gee whiz...I can read too.

Anyway, you're right...it is pointless arguing about it. Comparing DE graphs on a 370Z forum is silly. Amusing, but silly. haha

So, when are we going to see some dyno graphs of your setup?

Just curious what is the install cost of the GTM TT kit vs Boosted Performance kit?

Can both kits be uninstalled and car returned to stock just in case it needs to go back to dealer for warranty work?

What is the average professional install time of both kits?


Thanks in advance.

Boosted Performance

I can only speak for my kit..

All of my 350z customers have installed the kit themselves (this kit is no different). The kit can easly be removed, and the car can be returned back to stock, leaving no evidence (holes, cutting..ect) of there ever being a turbo kit installed.

A person (car owner in this case) who has worked on cars, can do the install of this kit in a weekend without much trouble. A shop should be able to do it in one day or less.

Thanks Sasha.

Mike@GTM

Install cost varies greatly depending on whether you do the work yourself or have a shop do it (and however much their labor rate is).

That said, we charge 25 hours to install our kit here in house. Like I mentioned earlier, our turbo kit can stay intact for maintenance operations (such as changing a clutch) and therefore has no impact on the time it takes to do maintenance.

When we designed our turbo kit, we took the approach of "converting" the car to a twin turbo design and as such it is a comprehensive system that integrates with the car. While it certainly can be uninstalled and the car put back to stock, it is fairly involved.

Thanks Mike.

WOW i never thought that i would see such a battle and the best part is that i dont have to watch it on PPV..lol

But all joking aside.... im a poor man that loves boot and fell in love with it ever sense i super charged my 06 hyundai tiburon back in the day. lol.. to this date in time i have no mods on the car because i dream of having that boost feeling again.

On that note I could never see myself spending more that $5500 or even $6000 for boost as much as i would love too.

What can i possibly do or get with a budget like that???

Mike@GTM

PM sent.

thanks just responded

Best bet, focus on some smaller mods, but line them up possibly for a turbo setup in the future maybe.
Good exhaust with maybe RTP, skip a full intake and do drop ins/MAF, some brake upgrades, oil cooler and while doing all that save a bit more and maybe in the future you can do a turbo setup.
