Yep, it looks like your numbers were right there. He's definitely not going to see crazy torque numbers which the motor will appreciate. :icon17:

I am gonna assume you stopped at 450 hp because of the auto trans? That kit handles some serious power, and the motor is good for about 600 whp. But $22k is steeeep.

I've got a 6MT and I know that the stock block is good for around 600whp. That price includes, the kit, an upgraded clutch assembly, replacement of the CSC, changing out the diff bushing, complete exhaust with test pipes (no cats), oil cooler and labor. I stopped at 450 because I'm not going to track my car and that number is more than sufficient for me. I've driven high horsepower cars and I'm comfortable at that level. Much beyond that and the adrenaline rush is rough on the body.... :eek::eek:

I know a lot of people have already chimmed in but let me give some information to help you.

1. Power for Single turbo and superchargers can range wildly. Your main concern is going to be TQ.

2. There are several single turbo kits on the market. there are only a handful of supercharger kits. Single turbos will have massive TQ fairly early on. the Vortech or stillen based superchargers will only see tq peak later in the RPM range. The RJM whipple will see high torque as early as 2800rpm and peak around 5500rpm and then level off around the torque you saw at 2800 rpm. A very flat torque curve.

3. stock components can handle only so much TQ load. the motor is anywhere from 500-550ftlbs (This could see as high as 700whp +/-). the Transmission maxes out at ~420-450ftlbs. PLEASE NOTE: the longevity of these components is drastically reduced at these power levels. Failure is not a matter of if but rather when...

4. Transmission upgrades. I would steer clear of level 10. This is my personal opinion after seeing a fully built trans by them pulled apart. however, here are the parts I would do:

Triple Plate Tq Converter (Only RJM has this)
Billet Flex Plate (Fast Intentions / RJM uses this one)

Next would be a truly upgraded valvebody.

Then finally machined baskets to accept more steel and carbon plates. (Only RJM does This)

If your budget is $10k I would keep saving. Your better off having $15k+ in hand when you go to do this. Trust me... Something always comes up and your build stalls because your waiting on money... Happens to a lot of guys!

Remind me: which of these were with E85 and pump, and what octane were you running? After seeing how yours was setup, I'm considering doing the same or similar (but probably meth since the nearest station with E85 is over 40 mins away)

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.

:iagree:

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 ? :icon14: 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.

:facepalm:

:shakes head:

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?


oh come on, why not LOL

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? :confused:

oooooooooooook. :shakes head: 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.......:ugh2:


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. :tiphat: :(

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.

didnt rustle anything. i'm just responding and correcting some of your *random rambling*. nice little touch you decided to add there......:facepalm:

just repeating that you're not against nissan doesnt change the fact that your view on comparisons between a gen 5 camaro and GTR are just asinine.:bowrofl:

if you're in the south that would give you even more reason to not go with those cars. that would be the worst just buying some big muscle car only to see 10 at every light like you're driving a fuckin civic :roflpuke2: at least you'd have plenty of people to make your purchase feel better over time. i mean misery does love company :rolleyes:

and we all are disappointed in nissan. you say it like you're the only one.

however, 2020 nismo GTR finally got the pieces it should have had (or had available as options) from the start.

Think when the motor home gets sold. I'm buying a Ferrari 488. :driving:

see now i should grab a C8 vette and we see if they claims of "ferrari performance" i've seen are true lol

I'll believe that when I see it. LOL

With only 660 HP? Are you paying attention Rusty? The Hellcat has 707, and a boosted Z can make that at the wheel! :stirthepot:

Yeah, Porsche has it all wrong too, they are still producing the 911. :stirthepot:

sir....if you are attending zdayz, please find me and i'll grab you a beer :bowrofl:

And even Porsche doesnt include stickers with their updates....

wellllll i mean with the GT3RS you can option to not get the stickers.....

or on a challenger/charger those idiots leave the yellow tape on the front lip for some reason :facepalm:

If I were to buy a GT3, Id leave out the stickers, theyre only reserved for special anniversary models!!

or you just wanna be sneaky making people think it's just a GT3......but boom its the RS without those big stickers on the doors lol

If I know one thing at all, I love the owners and this forum minus the fact the 350z owners are starting to be able to afford 370's and rice them up LOL!

GTR and more so, Z will always have a forever spot in my heart. It appears the whole purpose of this thread = to boost the Z will not happen on my 10k planned budget, nor be worth it keeping the 7A trans.

I'm disappointed with Nissan as we all are like you stated FP! No arguments to be made. I accept the fact GTR just isn't what I thought it'd be now that I am finally able to plan / afford one... I guess I am a HP guy and I just want lots of power. Ive always wanted to try something diff. This is my 2nd 370, I've owned b8 s4 audi, lifted 11' GMC Sierra, 5.0 mustang 13', and multiple sport bikes. I think I'm going to try muscle car once again! There's not many ZL1's around here, nor hellcats. So when they're spotted people "Awww" over them! I'm just not seeing it being worth it. Never meant to put them down.

I still love all you guys tho!! And will be on the forum until I sale it.

Which puzzles me, how much are 2012 370z sport/touring w/ 60k miles, FBO + TUNED and lots of misc. suspension / cosmetic mods going for these days?

What I paid for the motor home. I could have a 488 with money left over. :shakes head:

And a lot more friends :rofl2:

A used one not at a dealer. Those MF'ers will make you buy something else that they can't sell on the lot before they will let you have one. LOL I'll put 10 bucks on it. Watch and see.

@AstatenateZ. You really need to call sebs at specialty Z. He has proven to hold 450wtq for years on this platforms tranny.

550whp with 400+ wtq on this light car is one hell of a ride!

And yes, you can do it for under 10k.

You can consider going A2A SCed Z with some supported mods such as engine oil cooler, trans cooler, oil pan spacers, well ventilated front bumper (if any), larger radiator, lower temp thermostat, good oils along with periodic changing, and better flex plate. These will give you plenty of power down to the road within your budget and you will definitely enjoy driving your Z everyday :) Don't go overboard and there is no need to do so to risk your Z, especially you have budget concern. Centrifugal SC is friendly to our 7ATs. You should try it first and there may be enough power for you (at least I'm satisfied with that power level)

Don't be disappointed. The VQ motor has been so tolerant. I am an owner of both Z and GTR. They are both fun in driving but I have to say the feeling of driving Japanese muscle cars like those are still very much different from those Eurocars no matter how you modify them. For me, I have spent all the money and given all my love to Z because I love what it feedbacks to me everytime I did some mods to it. I admit our 7ATs have certain weak spots but you will be OK unless you go overboard and don't provide enough support for it. Getting a right charger system and you are good to go.

I love my Z but it is lacking room for GT traveling. My wife and I avoid the interstate on trips and travel the back roads. We have fun finding the twisties and truly enjoying the drive. The trip is as much as the destination and sometimes more!

With that said, my plan is to sell my Z when I retire in 2020 and purchase a GTR. The GTR is a true Grand Touring car to me. It has plenty of room and a trunk. It also has the performance of a super car without giving up comfort and room. Performance wise it compares to the new NSX but it is way more practical for touring. Call it old age but I want speed and comfort and some room to carry luggage.

Also, a lot of people only talk about the GTR for it's acceleration. It is much more than that! It handles superbly while still having a reasonably comfortable ride and it has room to carry enough for a week long get away.

When I get ready to sale my Z I will post it here on the forum first.

the trip to ZdayZ was much easier with the GTR vs the Z based on cargo space lol when packing the Z just forget you have a rear view mirror since topically it was packed to the roof.

GTR with back seats and a trunk was great. trunk is really deep so i got 90% of my stuff in there had like one little bag in the back seat.

also, fitting 2 golf bags is a touch easier than the Z but the Z will still handle 2 full size bags if you know how to put them in correctly.

FPenvy, just saying a ZL1 has a trunk and backseat too ;)
