I'm going F/I and I'm torn between 3 turbo kits it's between the powerlab gt35r kit, gtm stage 2 twin turbo kit, or the turbonetics kit. Now theres no need to flame me because I've been reading through a ton of threads and I've done all my research and this isn't a which kit is better thread I just want anyone's personal experience with each kit to help me make up my mind. Any info would be greatly appreciated thanks.

 

What is your budget?

 

I'm figuring to spend over 10 grand after the kit, bolt ons, clutch/flywheel, brakes, and suspension then installation and tuning so my budget is pretty much what I'm going to end up spending lol.

 

Then do the Powerlab but its going to be more like 12K+ if you are doing brakes too.

 

Alright yea I was figuring as much 2 quick questions. When does the powerlab kit begin to spool and make boost and when does it get full spool and full boost and another question thats a pretty stupid question can you use aftermarket headers with a single turbo kit or do you have to use the stock manifolds.

 

You will need to keep the stock manifolds. Not sure how the Powerlab spools, I have a Vortech but its about the best bang for the buck turbo out there.

 

I believe there is a member doing a PL install on headers right now. Look for a current PL build thread in this section.

Screw it - here you go: https://my350z.com/forum/forced-indu...b-install.html

 

turbonetics shouldnt even be an option in there

 

haha yea I know that the turbonetics shouldnt be an option i just kinda threw it in there for the discussion but after reading so much about it and the problems with the high aits and everything like that i wasn't too big on the kit. My only problem with the powerlab kit and the gtm twin kit is that you have to get rid of the windshield washer resevoir but that's not too big of a deal i guess. I was reading a bunch of threads about the powerlab kit and read that the ic pipe goin over the turbo gets extremely hot so would a turbo blanket and exhaust wrapping over every heat source pretty much solve the problem and cut down any high aits that may result.

 

I think you will be very happy with either the PowerLab or the GTM TT kit, just a matter of personal preference.

Good luck with your decision!

+1

but twins are different than single, but honestly for ease of access and looks is PL with a 35R

 

GTM or Powerlab....Either way you go, you will happy with it.

Now it is really on your budget.

I find that even with the 3.3 pretty much as soon as I mash it the tires spin. Only time I notice any sort of lag is if I'm starting out in 2nd gear or higher and get on it with the RPMs too low.

 

Im gonna say GTM kit because Ive always had two turbos as appose to having one but again its all about personal perference.

 

My PL is fully spooled by 3300... Either one is a great kit, you wont be let down. Also you CAN use aftermarket headers with the PL kit.. I am about to do it.

 

I did the powerlab kit with jetcoated strup headers and got great results. I start into boost at ~2300 rpms and get full boost at ~2700-2800 rpms. The headers really opened up the top end; I make power all the way to redline at 7200 rpms. I only dropped 10-20 hp between 6900 rpms and 7200 rpms. With the stock manifolds, the power will begin to drop off at 6300 rpms. I was making 450 hp and 400 ft/lb torque on a DD Dyno at ~ 9-10 pounds boost until I had it detuned a little. I am now running 425 hp and 385 ft/lb torque on a DD dyno at 8 lbs of boost. My dynos are on the Injected performance website at http://www.injectedblog.com/2009/01/...haltech-tuned/ The fit was very tight and I had a rattle from the top pipe hitting the header flange but was able to make a brace that resolved the problem. I think this rattle would be a problem even with the stock manifolds. The pipes are huge with this kit so fitment will be tight but most rattles can be fixed with header wrap, or putting a small dent in the pipe at the contact site. I know that the idea of denting the pipe scares some people but these pipes can flow 900+hp so a small dent will not impede flow too much.

Finally, I can't say enough good things about the guys at injected. They have been great to work with and earned my future business. I plan on a build and 550-600 hp by next year. good luck

 

James, those graphs show you making power slightly past 6300rpm's not to 7200rpm's...if your making power to there on a DD that is awesome.

 

the kit was designed with stock manifolds, so props for you doing it with aftermarket ones and with little modifications.


Alberto, I talked to Greg@Injected about that Powerlab build and he said thats 10psi and its true DD numbers, so dynojet thats probably about 495-500whp @ 10psi.... not bad at all, note the car run 600cc injectors an standalone ems in Haltech.



----------------------
OP, did you check the FI for n00bs thread?(no pun)

 

The reason that car makes so much power is the aftermarket headers. Any single turbo kit should run them. We made 40-70 more hp at the same boost levels on a car with the headers over the same setup without headers.

 

Sorry for the delayed reponse. They did not post the dyno sheets that I have as hard copies. My dyno results were ran to 7000+ rpms. I made power until 6900 rpms and then had a slight drop of ~10-20 hp to redline. I am not saying that I made huge power past 6300 rpm; but, I am not experiencing a big power drop after that point like I see on other people's dynos. Look closely at the posted IP powerlab dyno curve at 6300 rpms; the curve on my dyno sheet continues along until ~6900 then starts to drop. I will try and post if I can locate them.
