Insight Needed From Boosted Owners/Builders - Need Advice

The torque on a centrifugal like a vortech is the most forgiving on internals as it ramps in perfectly linearly. It's that shotgun of torque from a Whipple or turbo low in the rpm range that is harsh on them.

DO NOT GO LEVEL 10!!
It failed on me 3-4 times and several other people that I know failed as well. It can't hold anything above 540tq. Always an issue with flaring or slipping.

Right now I have IPT https://www.importperformancetrans.com/ So far it's holding well at 550tq since last year. Full summer of beating and 1 full day of drag track. Didn't skipped a beat. Car is going back to shop now to have few things upgraded on my twin turbo kit and then turn up the boost.

Yeah to be honest. I was looking at 09-12 model GTR’s . I know of the transmission issues and until 2014+ they finally make 545 crank hp. To me , this doesn’t justify the 60-75k price tag. As such the 09-12 models making 480-485 crank hp. Doesn’t justify 48-55k.

I am probably going to sale the Z soon and get a 2012-2013 ZL1 for 28-31k.

Even a 2016 + ZL1 for 50k that puts out 640. Hellcats are mid 40’s now and 707 crank hp...

I’ve loved GTR’s a long time. But I can’t justify spending 50k for 480 crank hp.... When I can spend 30k and have 580 crank and 5 bolt on's + tune and be at 600+ WHEEL hp.. ZL1 have Alcantara dashes and steering wheels, center seats, leather, stitching, etc. I mean for a Chevy, some nice features. I’ve sat in GTR’s and they don’t seem as “nice” as I thought you'd get. My 12 touring/sport feels more luxurious with the stitching, leather/suede seats, etc... I think my “omg GTR” has gotten to me. And I’m coming to reality. The GTR just isn’t what I thought it was

I saw your kits are $5999, that's an amazing deal for a new full A2A kit. My question is how much WHEEL hp is that good for ? Torque?

Is that whp/tq safe for the 7A in stock form?

And anything else I NEED to make it work? I.e, fuel management, etc. or is it just recommended ?

also is the Tial QRJ in your package or an extra amount? Want more info. If I can get away with spending 6k on kit, re tune and be at 450-500whp safely on a 7A I'd be interested.

I already have a 340lph FP, tuned on UpRev with a tuner who can remote tune me on a local dyno. So what else would I be out besides the 6k?

comparing a 12-13 ZL1, new ZL1, and hellcat to the GT-R is the dumbest thing i've seen today.

you're statement shows that you only car about the amount of HP and not what car you drive.

also, you must have a custom interior, because the interior in my GTR blows the Z's out of the water for materials and quality.

keep saving... if your going a vortech based kit you will want atleast $10k as a budget for the ohh **** or buffer needed in case something breaks. with the whipple or single turbo I would say $15k and twin turbo $20k

I also already answered the 7at capacity question. 400-420ftlbs peak anything above that is borrowed time... even at this level its borrowed time.

Well TG kit says around 450whp which equates to 360 ish TQ (from what dyno logs I've searched around and found) so that's a little under the 400-420 TQ range, correct?

I care about cost, power and luxurious amenities, with a ZL1 having 580, 30k price tag used market, and just as many luxurious amenities as a GTR (i.e, alcantara dash, seats + leather, diff driving modes, heads up display, fully loaded entertainment center with nav, etc.) it seems like a much better financial decision. I'm a numbers man, if it don't make dollars, it don't make sense, right?

I'm 25, I bought my own home at 22, never had help from anyone, I have no debt minus my 2 assets (home/car) , I have a 824 credit score, multiple lines of credit that are at 0% utilization, served 4 years in AF, and learned a thing or 2 about financial stability. I was raised by a single mom, and grew up broke, not knowing if I'd eat the next day. I play things smart, plan, and work my a$$ off for all I got.

I can't justify spending 49-55k for an 09-12 GTR that makes 480 crank hp or even 545 crank hp out of the 14+ GTR for 65-80k... when there's options like hellcats for 45k with 700 crank hp, or ZL1 for 30k with 580 crank hp.

Finally, comparing a Z to GTR interior, yes I can do it.

I have 3 local friends with GTR's. 2009, 2013 and 2017 . The suede dash is much nicer than Z, but aside from that. The cheap fake looking carbon fiber around the shifter, meh. The seats in my touring/sport are just as nice as the GTR's suede/leather as mine is suede/leather too, the steering wheels are the same cheaper feel leather, but still nice, and I'd actually prefer all the leather stitched on the center console around the dash/stereo in Z, as opposed to the cheap looking plastic the GTR uses.

And to top things off that killed my spirits and I felt the pain from my friends is that most people think the Z is better/ faster than a GTR. We've been stopped at gas stations and of course real car people know GTR > Z ... but 90% of people have complimented my car over a GTR because they see 2 seater vs 4 seater, they see the curves on a Z, long hood and assume = better. I sh*t you not, some lady was complimenting my car, my friends GTR pulls up, she asked what GTR stood for, and she said that's a sporty family car you got (assuming she meant because it had a backseat) and told my friend it looked like a fatter version of her Altima coupe. And I felt the pain in my own chest.. Nissan's not really doing anything with the Z's or GTR's (i.e, have you seen the 50th edition??) Nissan is becoming very dated, quickly. And as sad as I'll be I think I'm going to have to move on to a different brand who's making moves forward. Not keeping cars the exact same for a decade.

just an observer here but...the cars you're listing are radically different to drive. the comparisons you're making are nonsensical. the power figure is one small part of a large puzzle.

you do plan on driving these cars?

oooooooooooook.

i'll go in order and answer/respond each section above.

to your first point any 5th gen camaro is garbage and thats before we even get into how bad they look. so if thats how you wanna blow 30-40k be my guest i could use something fun to laugh at today. also the fact you compare a CHEVY interior (especially prior to C7 vette and gen 6 camaro) to the GTR is hysterical. makes me think you may be lying about knowing what these interiors even look like.......

no one asked for your life story nor is it needed in a car comparison conversation.....

so instead of a heavy car, with good power, that can out handle, and outrun the other options you listed but it's not the best option? sounds like its not the dollars making sense but more that you only car about power. hey you could just be a muscle guy so all power to you. i'm just stating that there's some errors in your comparisons and arguments.

god dammit we're back to interior stuff. only point i'll give you is i too wish the surrounding of the shifter area was better stock but $200-ish i can get a CF piece it's more just a pain to install. also, radio area has some CF and the rest isnt bad you're just nit-picking plus you said chevy interiors are better soooo.... owning both a Z and GTR, driving both often, and having the ability to literally side-by-side compare.......the GTR interior is all above the Z. i like my Z interior so dont think i'm being negative. however, the GTR is just better materials and feel all around. yes, there's better interiors in other cars o better materials but personally i'm a fan.

your final argument says a lot. it seems you're quite interested in recognition and not driving what drives you. personally i've loved the GTR and Z since i remember ever seeing them as a kid. granted i dont like certain models of each, but i do love them overall. i could care less that most people who know not a thing about cars and barely know how to put gas in their own thinks or claims to know about these cars. their opinions are mean less than nothing. i dont care what anyone thinks really. honestly a better way to live and makes things simple.

I'm not like most folks on here who say you need to have a bazillion dollars to boost....but your 7AT is the real problem. We haven't yet defined what is "safe" for that trans. It appears any boosted build on that stock 7AT is at risk of the trans failing and the options for built 7AT's appear both iffy and expensive. I know it's not the answer you wanted, but if you are on a budget then boosting an auto Z is going to require a significantly higher risk appetite than boosting in general (which carries its own share of risk already).

If you decide you want a boosted Z, find a cost effective way to exchange your car for a manual to boost or buy someone else's build that has a known good history (if such a thing even exists). Otherwise, it looks like a departure from the Z is in your future.

Sounds like a departure is soon to come as well.

I've seem to of rustled some jimmies, I do apologize. I'm just stating that (don't forget) the GTR is STILL my dream car, but they're going to have to come down in price before I consider it. 480/545 is just not enough for what you get, I had a 2013 5.0 in 2014 and had fun with it. Maybe I am a muscle car guy. I'm also in the south where v8 is everything. And ZL1's and Hellcats are like the icon locally. I also do not care what others think, simply stating the girl wasn't too far off, hinting that the GTR is dated and needs a redesign. As well as the Z. Nissan kind of upset with the whole auto show a week or so back. Didn't do much. No new Z, no new motor, nothing. Chevy at least evolves models, power, etc. Every few years to compete with Dodge and Ford.

To reiterate I am not bashing Nissan, I love my Z and GTR's I just can't justify it (right now) and am currently a little disappointed with Nissan.
