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

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
