R34 - Cost to Bring to 700HP?

I am contemplating purchasing an R34 in the next few months, and wanted to get an idea of what will need to be done and at what cost, to bring the stock R34 GTR to 700HP; bearing in mind that I am also going to be using the R34 for track days.

I would also be interested in knowing of any good performance shops in the San Francisco Bay Area that could perform most of the modifications.

Any input would be greatly appreciated.

:D

Now this is just my opinion, but I would go to a shop and say "I want 700 at the wheels, how much will it cost" I would take the time to learn your car in and out and build it up to that. That way not only can you insure that you don't have any weak points, but you will also have a very good grasp of what your car can do.

Now off the top of my head I don't know how much it would cost, but lets look at the big things you will need.

Crankshaft
Con Rods
Pistons
Cams
Cam gears
Pullys
Uprated Turbo
Big fuckoff IC
I/H/E
Up pipe
Clutch
Gearbox
Propshaft
Driveshafts
Boost controll
Fuel computer
Fuel pump(s)
Injectors
Enlarged fuel rail
Enlarged throttle body
Fuel pressure regulator
Expensive ECU
Uhhh lets see
Gauges: Boost, EGT, A/F, Oil Pressure, Oil Temp, Fuel Pressure.
Front Lip (to keep the damn thing on the ground)
Wheels and Tires...

And all the little odds and ends I missed :D

Thanks for the breakdown. It is a good place to start. :)

Not a problem :)

Oh yea, can't forget braided lines, silicon hoses, high pressure fittings that sort of little stuff.

Oh yea, and some kind of Mass Air dealie. HKS VPC (Do they still make these?)

Well i do happen to have some questions. I wont get my licence for about3 years. But i think it will be good to know what i want! I'm looking for a skyline thats really good to race. Alot of poeple say the GT-R is a really good model. Could i have some help in whick is the top.

I talked to one of the local guys with a 700 Skyline, he is in the car well over $100,000. So you will need a lot of cash.

Everything Gonthrax mentioned, then a dyno tune.

Yup, mucho cash :( But from what I hear, after you hit 700, 1000 is basicaly a tuning challenge, you don't have to buy many more big parts. I mean, you might want to start running 3 fuel pumps, or you might want to uprate your turbos. But you'll almost get more power from mapping your ignition curves then ever before.

Ankhlion: Were do you live? If you live in the US, uhhh how do I put this, are you... Well endowed... Financialy? If you arn't, then go grab yourself an R32 GTSt to get used to the way skylines behave, then find an R32 GTR :)

Gonthrax,

Ok, how do I put this. Step away from the car mags. I said step away, kind Sir.

Now go pick up a wrench:D

Depending what you want 700whp as the guys seem to think, or 700hp as it seems from your post. 700 crank hp is about $10-12k + the price of car. That will be a car that still behaves well mannered on track. 700whp for $10k is propably possible as well but it would not be a good track car, more suited for strip.

:( I don't have anything to wrench on :(

And I've only bought 4 car mags in my life:rolleyes:

i heard alot of the power is restricted to make the car legal in most countries, and that it takes very little to unleash the power these beasts are capable of.

sami,

Could I hear your 700hp for 10k recipe? That would be very awesome.

Bulldog,

Go to www.motorex.net for 4k your at 366hp. Not bad, but that is what they advertise, so number are going to be inflated. Dyno numbers are crap, about the only thing itsw good for is to see how well your car is tuned. The numbers that mean anything is either on the race course, or on the 1/4 mile. Dyno Queens are just that.

$2500 for HKS GT2530's
$1000 for 720cc injectors
$1200 for (HKS) 272 cams/gears/springs
$0700 for IC
$0300 for (HKS) metal headgasket
$1300 for Apex'i PowerFC + controller
$0400 for Apex'i AVC-R
$1200 for Intakes + exhaust
$2000 for twin plate clutch
$0395 for Nismo fuel pump
$0230 for Nismo fuel pressure regulator
-------
$11225 for total

A little over $11k but then again, IC might not be needed and you could save money on clutch too. Some of the prices are estimates (already had them on my car), some are what I actually paid (turbos, cams, headgasket, fuel pump/regulator etc.). Injectors I got slightly used for $600 so I saved some there as well.

sami,

What about the tranny, I have read that is one of the weakest points of the GTR any truth to that?

What about installation? Is that included in the price?
Do you install all of your parts?


That would be awesome for a road course car:)

Tranny is a whole different story. It might hold, it might not, 3rd gear is what I've heard is the weakest link but I think mine will break 4th first. It's still going but once it is gone, I will propably put in a dog box.

That's just for parts. As far as installation, one of the local tuning shops are happy to work on the car and gain fame... :)

Since mine doesn't have Brembos, brakes will need to be upgraded. Haven't decided what route I will take, propably totally new custom made brakes, around $2000.

Most of the GTR guys here hate Brembos, they had some very choice words about them, like "complete fuckin crap" their words not mine:D

Still a lot better than the stock brakes... :(

Installation is going to cost a mint, so that 10-12k is looking a bit optimistic:D


So, you do plan on racing when your done, don't you?

Installation, I would said another $1-2k.

Installation is done but we need to tune it for a little more boost, right now it is running on only 1bar, 1.5-1.7bar is where I want to be. Racing, no. I plan to run it on track hard but it will not see any bumber to bumber action and drag racing I'm not interested in.

What about those stoptech (StopTek?) brakes, I've been hearing good things about them, and Willwood too

Willwood good stuff, not sure about the other.

Aye, they've been around for ever :)

I got quoted by the top tuners over here at £40,000 to get an awesome 700hp car. this includes triple plate clutch, 6 speed sequential, AP brakes, Bilstein dampers/Eibach springs and all the little extras that are needed to make the car handle well too. The parts are all first class, and this price included labour too. After 700bhp its is easy to push the power up with little work,but to push it up, and be reliable is more difficult, it involves big turbos,and real advanced fuel systems etc. it can get VERY expensive after that

i personally got ap racing caliper's
http://www.automotiveforums.com/vbulletin/t67928.html they are great.

i believe AP to be the best brakes.are you often in the UK?i have seen a couple of cars Abbey Motorsport have done, i like them,but to be honest i still think TDI are slightly better,i mean theyve never had a skyline engine done by them blow over however many years (about 12 i think)

why do you think i picked them for.

Yo my man...:) mine has about 525 ponies on all 4 wheels...the engine hp is anybody's guess....the whole shebang cost about the equivalent of 25k USD...including ecus/tuning cost...flew in Nagata San of Top Secret to do that...shared cost with 2 others.../AP 14 inch six pot kit n suspensions tune up.
The APs are good but well, after about a year and a half of track duty the disk warped!!But Malaysia is hot...really hot so that may be the reason...
Now my Malaysian mech told me he could extract more low end torque and more hp at the boost I am running ie 1.55 bar...so maybe next month the car will be on the dyno again! Had a bet with him...if he fails to improve my power curve he pays me...if he improves it, I pay him...so lets see....

when on track i had brembos and i thought they were great at the time then after i got my ap's they worked ten times better and they last longer and that meaning they are fade free for alot longer.hehe they were worth it.:smoker2:

This isn't a skyline but here's a kit for a supra to get 1200HP for 33k.

R33,

That sounds like a sweet deal, but remember that each dyno will tell you a different output. Some maybe very close to each other, but some can be way out.

For reliable 700hp its going to cost a lot more than some people think. Yes the GTR is a great platform to start with, but its still not cheap. I personally will be shooting for 500 to the crank, you can do that fairly cheap, after that you start digging a lot deeper into the pockets.

Hows the Civic?

Way overpriced...

Sky, what I will do is to dyno the car on his 4wd dyno before and after. Let's see what he can do with the car. But I have the feeling that he will actually pull it off because he is about the best HKS trained tuner around here.
You are targetting 500 at the crank? As you put it, that wud be quite easy and relatively cheap to achieve. And with that kinda power by retaining the stock turbos, your low end response wud be excellent. What more, your 32 is about 1OOkg lighter than the other GTRs. BTW, what is it churning out now?

I would imagine about 350-380 at the crank. It has been chipped, R34 turbos, boost controller, new exhaust with no cat, and a K&N air filter.

The turbos spool up pretty quick, but if I compare it to my Stang, the Stang's torque is awesome compared to the GTR. I really like torque, so I am going to try to get more power down low. I know N2O is not a good idea unless it a direct port injection, so that is out of the question. I am going to build a water sprayer for the intercooler, and a air induction of some sort to get more cold air into the stock air box. I was going to go with a pod, but the more reading I do on the subject I might as well spend a few more hours in the garage and fabricate a kit for the stock air box. It seems to have about the same effect on HP, we will see?

The wife loves the car, so right now she is looking into the legal importing of the car back to the states. Since she is an attorney, she understands all the DOT, EPA, and National Highway terminology(sp) better than I do, so more power to her.

Did you see Bathhurst this weekend, that was awesome. I was pullin for thew Falcon, but I knew the Holdon was going to win. That Falcon looks sweet.

Actually, as for the power I would like to be where your at, but the wife said No. Plus with the Stang, I can beat that up and if it breaks, it will only cost me a few thou to get it back on the road:)

The NOS sounds interesting although I have heard lotsa horror stories about the engine blowing up and all. Do you know whether NOS is the devil that people seem to make it out to be? If it is tuned properly, will it still blow up engines especially if used with turbos? I for one would love to put in a dry NOS system...just to supplement my low end and when the car hits say 4OOOrpm and the turbos are singing, the NOS is gradually switched off. Waddaya think? Is it okay?
The Stang's supercharger is always gonna smoke the GTR till the GTR is on the 3rd gear probably. It's like the EVOs jumping ahead of my GTR for the first 1OO meters or so on a quarter mile or out of a tight corner. Actually, someone in Australia actually sugested that i installed a supercharger on the GTR. If that could be done up to say 500 ponies, I bet it wud be a blast!
The intercooler sprayer sounds cool but where r u gonna put the water tank...I was thinking about it too but then I thought I wud run out of water pretty fast in this hot climate...What about water injection mate? Do you know whether it is okay?
Glad to hear that the missus likes the GTR. I could imagine your missus arriving Chancery Lane in your 32...a sight to behold...:D

N2O is very safe, but you have know its limitations. If you try to push it, that is when things start to blow. I have everything from the Stang, but the wife told me she would divorce me if I hooked it up. I am going to see my Lawyer Friday:p

They make progressive kits for N2O that you can adjust how much you want at what rmp you want, when you wantit to come on, and when you want it to go off.

I have a window switch, so if I can talk the wife into it, it would only be a 50shot, with it turning on at 4000rpms, and shut it off at 6000rpms. I would not dare go any further than that.

You do know that a 50 shot on a turbo is like 100 shot on a N/A engine, so in reality you get more bang for the buck. With the cooling effect, your boost levels should drop as well.

Water injection, I am thinking about it. I want to optimis what I have now, keep the car very streetable, until I take it back to the states. Then I plan on modding the crap out of it. :)

Why? I don't know how N2O systems work but it all depends on how much oxygen you are burning. The little I have seen N2O's I don't think it is going through the turbo so to me it would seem that a 50 shot would be a 50 shot regardless of whether a turbo or NA. ?

The only thing I can think of is cooling but you're not spraying to the intake, are you? To gain significant hp you would have to cool the intake air which would mean more oxygen to burn.

A 50 shot in a Turbo or Supercharged engine will drastically lower the intake charge tepmerature. You are cooling down the intake. It might not be exactly an increase of 100%, but it should be fairly close.

I should not say 100%, but doubling the power out. A lot of the mustang guys will turn the nozzle into the air stream to get a better distrabution. I will do the same thing. I have seen 302 with well over 100,000 miles on them, the main thing is not to get greedy:)

That explains it a little bit. I'm ignorant about N2O systems and I choose to be in the future too... :)

One thing that concerns me about N2O is the fuel management, it must be a bitch when you have tuned your car and then add N2O?

Well for my Stang, I have a Tweecer. Its an interface like a MOTEC I guess, but you can switch between 4 different setting. You can do one dyno tune for just boost in position 1, then switch it to position 2 and dyno tune for Boost, and N2O. You can have position 3 for just street, and 4 for what ever.

You can adjust on the fly as well, my Stang rocks:)

I still am learning about the GTRs.

Yes, I have PowerFC so I'm familiar with that but actually do the tuning for N2O...

N2O tuning, cut back a degree or two, add fuel, and a cooler plug. Your there.:)

Hey, I am not even going into this like Sean did. 150 shot, that man is crazy:eek:

I am actually going to be shooting around 40, so to tune that you don't have to do anything, as long as your on the rich side.

That sounds cool Sky. Erm...when r u comin' to M'sia? Coz I want u to do it on my car...:D

Ah Sir, you have enough power:D Could you please stop taking a hit off the "Go Fast Crack Pipe"

The "Go Fast Crack Pipe" is now discarded...for the meantime...I am now on my "Big Torque Sniffin' Powder"....:D
