Insight Needed From Boosted Owners/Builders - Need Advice
 

So I've owned the Z for nearly 2 years now. I've pretty much done every bolt on + tuned. It's mainly for looks as it's low, got wide wheels, I am looking at switching it up. Light wheels, raise car back up to 100% functional, meaty tires, etc.
My main dilemma is I just accepted a new IT position at work, bought a house. Fortunate enough to not have kids or a wife. Only a girlfriend who mostly supports my car addiction.

I am in the market for a used GTR (around 55-65k), but obviously my financial mindset (I am fortunate to have at a young age) tells me just boost the Z and enjoy it for a bit longer until I'm 100% comfortable affording the GTR, as I am with the Z.

Which brings me to my questions for the Boosted owners/builders/shops etc.


Realistically, what #'s should I expect with a single turbo or A2A SC kit? With looking at GTR's I'd like to be around 550-600whp.
The weak link would be the 7A trans I'm assuming from research, which leads me to my next question,

What's all needed to rebuild the 7A trans to handle 550-600? And costs associated? Any companies offer rebuild kits, solenoids, etc to beef it up?

I've looked at a few SC/Turbo kits,
Stillen with SOHO A2A upgrade w/ 9lb pulley upgrade (580whp/427tq)
SOHO Stage 1 (540whp/465TQ) for $7899 or
SOHO Stage 2 kit for $8999 with 570whp/498TQ



I'm looking to stay under 10k, The best bang for the buck would prob be a lightly used Stillen, + $1999 for A2A kit and then whatever parts needed for 7A to withstand around 550-600whp/420-500tq.

I want some first hand experience (before pulling the trigger) by builders or owners on costs associated with, how much power to realistically expect, etc. Any info is much appreciated.

Best suggestion: Call Kevin at Fast Intentions and talk to him, then maybe call Sasha at Boosted Performance and have the same conversation. I called Kevin and decided that when I go boosted, I'm taking the car to FI for the install, not because I can't do the work, but I'd rather the experts do it. That way it gets done correctly, and I can enjoy it on the drive home. :twocents:

Don't leave out the supporting mods. Injectors, fuel system, clutch, etc. It freaking adds up quick. 20k would be a good start. If you need more, save up for it. Insurance on a GTR at a young age would be outrageous. You better check before you leap if you want to go that route.

Kevin quoted me $22k for a TT setup with all supporting mods, OTD. That included the tune by Seb. Of course, I'm looking for about 450hp. :yum:

pretty much Level 10 transmissions make the only upgraded 7AT setup that can hold 1000hp

I priced mine out a while ago with the 7AT upgrades, supporting mods, etc and it was going to be around $20k, not to mention the shipping costs to get my car to FI from Chicago.... I’m also mildly concerned about reliability and considering this is my daily, I decided not to pull the trigger. I think you’re better of getting the GTR and doing downpipes, intakes, injectors, along with a cob tuning kit to get around 600 hp!

You ever price insurance for a GT-R? It's is one of the highest to insure, plus the so called GT-R tax on mods. Just ask FPenvy. :rofl2:

Good point on insurance. I guess for mods it depends on how far you go. Cob access/tuner, injectors, down pipe, intakes would be a lot cheaper than 20k.

I actually quoted with progressive, I am 25. I have military discount, home owners, multi policy, etc and a Platinum member with nothing on my record. I pay $184 for all the bells and whistles full coverage on my 12' Z. I was quoted just under $300 for a 2012-2014 GTR with all the same coverages. Wasn't ridiculous at all. What is ridiculous is 20k into my current Z, I had NO clue it would be that much, even with supporting mods. Thanks for all the info. I was thinking roughly 8k for SOHO kit or around 6k for used Stillen SC + A2A kit and then supporting mods, trans mods = $10k or so... 20k is too much for me, I won't be owning this too much longer. GTR's are getting cheaper by the month. I'll just stick it out. Maybe just do some more interior mods.

I planned on installing at a local speed shop with the help of some pros. I am a 100% diy'er. Thanks for the contact info.

5k just for that, it's the only option? With me being at 550-600 is this required? I want to be safe and she gets the best. But I wasn't thinking most people who go a mild 550-600 on a Stillen + A2A kit "had" to run this?

Yeah, that's the average price everyone on here is saying, I planned for supporting mods about 8k for turbo or SC kit and some other misc items and got around 10k, def not 20k but that's why I got on here. Think I'll go GTR next year then. Not willing to drop 20k into a 370z that is already 7 years old. When I have have a 5-7 year old dream car of mine.

See comment above to @Spooler , I have a clean record, 25, military discount, multi policy discount, I'm at just below $200 now with the Z and I was quoted for 2012-2014 to be right at $300 monthly. I didn't think that was bad. But I do agree aftermarket mods are crazy priced (exhaust, intakes, bov, tuners, etc) but I'd go lightly modded. I just want a simple bolt on, reliable power GTR, lowered, Advan wheels and some meaty tires and call it a day.

Absolutely agree 100% ... :tup:

GTR it is :tup:Thanks for the insight!

That is 1800 ever 6 months. That's not cheap. Get one ticket and they will drop you like a bad habbit.

With my income. $290 a month to me isn’t bad. Also, $184 right now with a Z . So only going up $106 isn’t much. Also I’m platinum which has a small accident forgiveness. In 8 months I’ll be at diamond savings and that’ll discount more + gives large accident forgiveness. Good friend is a lawyer. Already kept 2 speeding tickets off my record. So I have nothing on my record. My friend who’s the same age as me own a small car lot and owns a GTR 2014 and pays like $240 for full coverage, with Geico .

The main thing is the $750-900 car payment. But I mean honestly my brother has a 2017 F250 Platinum and his payment is $1180 for a truck... so that helps me sleep a little better at night :rofl2:

I was in the same boat planning out a TT build for the Z went back and forth for years on it. Ended up just buying a GTR and now the Z is my summer daily.

GTR tax is real. Was gonna go cheaper route with the SBD700 kit for 5k but have now changed my mind going with better parts so FBO will end up being more like closer to 10k when all said and done.

22k for 450hp :bowrofl:

Honestly this is your best bet. You've had your fun with the Z. As recently as a couple months ago I was considering GTR to the that if I had run into a really good deal on a 14+ it would've been trade time. And I was balls deep in my build. I was that ready that I would've taken the hit on built motor , boost and the whole bag.
Today I'd have to be finished building but the threat now is if a ZO6 or a 14+ GTR attract my interest.

So.... :gtfo2:

Unfortunately it won't be possible to achieve your goal under 10K (go boosted and have 7AT rebuilt at the same time...). To the best of my knwledge, we have three feasible solutions in our AT rebuild. However, there have been several tragedies reported. So far it seems to me that there is no absolutely reliable transmission rebuild. Chance is yours to take 😢😢😢

You can boost on a budget (I did!) but to stay under $10k you needed to start out with a 6MT and adjust your power goals closer to 500whp. Upgrading the 7AT is half the budget on its own.

If I come across a 2016+ Viper ACR or a older ACR-X at the right price. It could be game over. :driving:

Shut up! There is a 2012 I think on Winding Road for $125k. So put up or shut up!

The delima with an auto is the trans. Go FI and you won't have to worry about the trans. Cycy was the first FI auto trans and it made 700whp. Of course it was not left there but still over 600whp and is still running today with no issues. Cy will be at ZDAYZ.

Rusty got called out!! Fund manager might be getting nervous. Don't do it Rusty!! IRS tore me a new bunghole.

:rofl2: Like I said. The price would have to be right.

GTR is a money pit when you start adding up cost over time, the maintenance cost are super car cost. Maybe you like giving the insurance company money. I pay less insurance for four vehicles than you will play on the GTR with you low rate. And no they are not all beaters as my wife's car is an 2014 Audi s5 to go along with my 2010 Nismo, 99 Miata and a 2002 GMC 4x4 diesel pickup. They are all paid off except for the Audi. Anyway my build will be exactly like Spooler's and be rarer than a GTR. GTR techs will stop working on a GTR to look at and admire my Z the few times I have taken it to a dealer. I asked GTR tech that installed my APR wing if he drove my car after he installed my wing...he paused and then laughed and said it's faster than a GTR!

To each their own, I consider getting a GTR as well at one point but the numbers and the GTR tax didn't make since to me. I had my eyes on the 14 Track Addition.

The price is right it is race ready and comes with two or three set of Forgeline wheels and tires. I ran in the TransAm series...so if you want some get some!

LMAO, he doesn't really want one. He has champagne taste and a beer wallet like most of us here.

If a cop see's you in a GTR speeding you are getting a ticket. No mercy for you. Then you can wave bye bye to having insurance. Back in the 90's in my 300zxtt they always clocked my. Every time. I had to be very choosey where I had fun at. The way they see it is if you have money for a GTR, you have money to pay the ticket.

:yum:

Anyone want to buy a motorhome?

The IRS has ripped my azzhole wide open for the last 3 years. :mad: 2016 - $28,000. 2017 - $18,000. 2018 - $2,800. :mad:

Dang man, you are working part time to pay your taxes. You gotta get that dollar amount you are pulling out of your retirement each year down lower.

It was Obombacare that screwed us over. Qualified for the tax breaks at the beginning of the year. At the end of the year. Find out that we no longer qualified for the tax breaks and had to repay everything back for the year plus some. No longer on Obombocare. On a christian based health care for less then half the price. Don't have to worry about qualifying for the tax breaks anymore.

Tell me about it. I screwed myself this year. My pension would've had me in the safe zone then my contract work plus mad money put me in the IRS bitch zone. I ran outta stuff to deduct.

Same here.

LOL, yep this is a beauty for sure and the prices are not going down on ACRs...they are going up in value. I track with a guy that owns 4 Vipers including an ACR. He will not track the ACR because he wants to keep it in meant condition.

I driven a couple of them on the track. :driving: :yum: Torque everywhere. The last one I drove last spring had a sequential in it. :yum: :yum: It was just eye popping, wet your pants type of driving. For me, it's just one of those cars that is JUST out of reach. :shakes head: If wifey and me was still working full work. It would have been a done deal. And I'm not dipping into my retirement money. I'm still upset that I didn't get that '06 just before I bought my Z. If I did, I wouldn't been on this forum.

Copy that...first world problems and the blessing many times is not getting what we want. My life is so much richer because I made the mistake of buying a Z and now I get to call you knuckleheads brother and sister, LMAO!

Just a couple notes

You stated 420-500 TQ. With the SC, your max TQ will be < 450
You stated $6000 for used stillen kit and air to air. Topgunz NEW FULL air to air supercharger kit is only $5650 through April. $5999 after that.
SOHO dyno numbers don’t include running an air filter. You probably don’t wanna do that.

Torque on mine was 491, but, I was running a Turbo Guard screen :stirthepot:

How much HP and what did your curve look like? 420 Tq is enough for 600 HP at 7500. Topgunz posted plot for his kit was 440 TQ.

I had 4 different power levels with my wastegate/ebc. High boost was 658whp.

Yep. So my numbers were right on. Didn’t want him thinking he’d be pushing crazy TQ for the hp he was shooting for. 550-600
