have to disagree Joe - theres a lot of people out there with too much money and not enough brains ..... although money helps theres no point having a shitload of dough a car and no idea how to go about it!

I don't think a 60ft of 2.3 entitles me to a 'great driver award'.

Granted it was on crappy 205's.

13.3 and a 2.3 60ft with only 4500rpm of useable power. Put 255's on the back of my car and in it's present state it will run 12's with the average yobbo driving.

IMACUL8,

The plan of attack in my case was:

decided I wanted a 'WORK' car with--

1)reasonable fuel ecconomy

2) ride comfort

3)nice accelleration

4)without alot of noise.

Quantified it :

1) Close to 9 to 10L/100km

2) Keep my ass from feeling like it's been kicked by a horse on long journeys

3) A mid 13 second 1/4 would be nice along with strong in gear overtaking power, calculated this would mean around 270hp @ motor.

4) I can carry on a conversation at normal levels when driving (car kit for phone/work)

As an example.

after quantifing the next step is to go out and find the solution.

My approach basically enhances the engine reponse and efficiency.The power level is conservative due to the restraint of noise and fuel ecconomy.

There is a guy in adelaide whose run a 12 second pass on a stockish turbo, I think it was slightly hiflo in japan. He's got just over 210kw@rear wheels, about 280hp. I've got 245hp, yet I still havent been able to crack a 13 yet. Comes back to how you drive the car, those who know what they are doing or have no mechanical sympathy will probably get the best results. I know where my problem lies, its in my launch. When the drags open up again I'm hoping to go down and work on it. That said with the turbo and ecu I'm putting it, it will bring my mod bill to about $10k, I'll only know if I have chosen the right turbo till after its bolted on, from what people (like steve and grant) have said it will produce the goods and I should make 350hp easily. I've also noticed that 245hp in my car does seem quite boring it doesnt have the "seat of the pants" quickness some other cars have with simular mods... *shrug* could be I'm used to the delivery of power from my car.

Jay95R33,

I agree about diversity. Unfortunately the 'diverse' can be replaced by 'ignorant' , 'uneducated' and 'missinformed'.

I too agree, although my reply was based on the comment "I dont understand your infatuation with dyno hp figures... ", and not so much on the misinformation and lack of direction.

I suppose I was just trying to say that everyone is different and we have to respect that, no matter what they decide what their goals are.

Well at last, a decent thread of conversation.

Good point, as rev210 is the ambassador for "throwing lotsa cash into a skyline DOESN'T mean it'll be fast" (in all cases)

I'm a prime example of spent too much already, and still haven't got a decent(quick) time.

That said, the only performance mods I have on my car is, 3" Exhaust, POD, CAI, EBC, SAFC-II, and clutch. The rest is aesthetic.

I'm not happy about pulling a 14.5, but what can ya do?

My next mods are Dump Pipe, Wrap exhaust and Cam Gear... here's hoping for a mid-low 13....

Back on topic: If that fails, I'll be seriously looking at Diff Cradle kits for traction, rear suspension setups and more-so tyre combinations.

Anyone seen that HPI video where they used different tyres and decreased 1/4mi times by nearly a second ?

ok let me rephrase that

so "Person with good brain and most amount of money will have fastest car"

cheeers

Joe:rolleyes:

suspension is very underated on a skyline

a mate of mine with a 4 door skline and the same mods as u kim, runs a suspension shop set his car up really well and ran a 13.2 with 248 rwhp on formaz's dyno

other things that people neglect to look at is management. you can bolt all you want onto an engine but if its not tuned properly it aint gunnah run well. peak power doesnt reflect how fast a car is as we all know

adam took the words outta my mouth, management is one area i dun think anyone pointed out apart from adam, suspension is a definate area that is often missed out when it comes to modfying another is engine management, i've heard plenty say that wanna bolt this and that go fast parts on, and when they do their car runs like a bitch coz it hasn't got somethin even the slightest bit decent to manage the engine :( that allows them to tune the car to maximum potential :)

little things like removing the front headlight for optimum air flow to filter does work as bully has proven :) money ain't always the answer! i don't think bully paid a cent to remove his headlight and he managed to bring his 1/4 mile time down :)

adrian :D

I think this thread and the low down HP/torque thread go hand in hand. Most of us drive daily driven cars and want good low down low rpm response. For this I would do the following (if I was keeping the stock turbo and management):

full 3" turbo back exhaust

light weight flywheel

bleed valve set to around 10psi

safc2

some 9" wide rims on rear 17x9 or 18x9 to fit 265 rubber on

autoclutch 2000pound pressure plate clutch from ross

diff craddle set

I'd expect this car to run low 13's back to back and seeing as it isnt used on the track the stock intercooler should do fine. At most you'd probably spend $5k all up on that and it'd kick ass.

The cheapest form of management would be the wolf or the powerfc, both will set you back aruond $2k installed and tuned. I wouldnt bother unless you plan to change the turbo/injectors or are chasing huge HP a SAFC2 will do the job to lean the fuel out at high RPM. MRGTST's r33 has a re-written jap rom in his ecu and that makes over 280hp with his other mods, yet he still hasnt run a 13 :D

    • You've just discovered a really good reason to tell yourself, yes, I do need to buy an aftermarket ECU. Put the MAF in the bin. Slap in the new ECU and have a think about what turbo sounds you prefer.  Do you want a 90's style BOV wooosh? Do you want a hektik tsututututu?  Mate, can't go wrong. Just gotta get that ECU and the world is your oyster. 
    • Hi. Iam just curisou about this topic. I saw this video. It is about Greddy Type FV2. I know that BoVs are about that sound but how and when to use it? I read some topic here and from what i have understand on stock RB with MAF there will be some "problems" if you use this BoV? It vents the air in to the atmosphere and the MAF on stock car needs this air back in to the intake and not out? Or is it wrong? If so...i saw you can put some adaptor to circule air back...but does that not "loose" that sound? I saw another BoV from Turbosmart and it has two "exhaust" like ports? One is for the stock tubing for letting air back and one is for "sound" and let the air in the atmosphere? Can someone please explain? This is the Greddy one:  And this is the Turbosmart.     THANK YOU!! EDIT: So i read about this topic some more and i if i understand that correctly: That Greddy can function either like BoV or 100% Bypass valve? And that Turbosmart is what they called hybrid so you can adjust what and how many air can be vented out or back in? Is this right? THX!
    • That dirty voltage drop is the culprit I suspect 
    • i cant get them all in 1 screenshot unfortunately as i just dont know how to move things around tbh, but they are all from the same log and the line crosses at the same point for all of them
    • It's about time I start work on my sun tan. So I knocked up a few parts that will all combine together to become my new power steering reservoir. Now just to produce an abundance of UV and IR rays while melting a heap of bits of alu to become one... Well, that's after I put one more hole in it for the return line to plumb to. It likely won't be this weekend, as Sunday I'm meant to be in doing some last minute stuff to the AMG race car, and the weekend after will be filled with non my Skyline stuff, followed by Bathurst 6 hour. So I don't expect to get to melt metal for at least 3 weeks.   I also managed to stuff up and start cutting the hole for the res to pump pipe on the wrong side of the line... It means instead of the lines being nice and tight against the inner guard, they'll be out off the guard.    The size of it means I should end up with about 1.8L of power steering fluid, and still have space for another half a litre before it reaches the overflow/breather. This is wayyyyyyy more capacity than factory, which should help keep Powersteer oil temps lower, and the design hopefully allows it to prevent any aerated oil being able to makes its way down to the bottom as it'll have a couple of baffles and some hopeful trickery to force air bubbles away from the bottom.
