Pay It Forward Design Challenge [B1418, Closed]

[strop]

OOH LOSER PAYS A FORFEIT!!!

[HighOctaneLove]

I would like to join up... This sort of thing sounds like it'll be interesting at the very least

[Chipskate]

Oh my, this sounds completely bonkers. Count me in

[VicVictory]

What happens if one of us (most likely me) fail?

I think Strop's idea is fair enough. You have to make an absolutely embarrassing public submission... Maybe something written on your car's hood in a CTC or something like that. Whatever you/your tormentor come up with (within reason)

[np1993]

sign me up!

[8bs]

OOH LOSER PAYS A FORFEIT!!!

are we allowed to use monopoly money?

[VicVictory]

Well, uhm, I'm paying my forfeit to Strop in the form of... really garish writing on my next public submission.

But like I said, whatever you guys come up with within reason.

[3rayman3]

I think after each round of challenges we should mix up the order so we don't keep receiving challenges from the same person and keep giving challenges to the same person

[strop]

Agreed. Alright, since the original challenge was given to me by VicVictory, I'll kick things off.

______________________________________________________________________________________________

The story begins here, with this loveable piece of crap. I bagged it out so much that VicVictory said to me, fine, let's see what you can do with it. I said ok, try me. What do you want? Then he gave me all this weird stuff that I don't normally bother with at all. Offroad? What for? I have to use old tech with negative quality sliders? What the crap is that!?

The scenario is as follows:

2nd cousin J.T. Bubba got a hand-me-down '57 Stubby from his great granddaddy in 1995. This is the great nephew of the original Jethro Bubba, in case you were wondering... but the whole family loved the Stubby series because they were so cheap and durable.

Anyway, it was rather dilapidated when he got it out to the bayou. Thinking as practically as he could he figured that he'd need to make it 4WD. he didn't have the best tools or supplies available, but DID have a rather nice down-the-street neighbor who had a ... collection (read: junkyard) of old cars and trucks.

Must retain suspension type (McPherson/Leaf Spring).
Must be AWD.
Must retain ladder frame construction.
All existing negative sliders must remain untouched EXCEPT: engine (See below) and tires, transmission, and suspension (limited to +2 max).
Body year: 1957
No aero cladding. Lips and rear wings unrestricted (assumed to have pulled from the junk yard)

Engine/transmission:
Must choose from one of the following three design set restrictions, which represent junkyard engines

...

Set 2 (6 cylinder, roughly simulating a small-displacement import I-6 from the 80's)
Tech year 1983
No maximum displacement (that particular body is already restricting)
standard intake, tubular headers
DOHC (2- or 4- valve)
No VVT/L (probably not available that year, but just to be sure.)
cam profile between 40 and 55
A/F mixture EXACTLY 13.5:1
5-speed manual, closeness no lower than 35, must turn no more than 2750 RPM at 100 kph
Max boost (if turbo'ed) is 8.0psi. The engine is old and fragile, and would never stand the pressure.
Block quality slider may go up to +3, representing the good condition of the block. Head is at -1 (getting old and high mileage). Fuel system at 0. Exhaust MAY go up to +2 (representing some good parts he found)

...

Your goal? A mud bogger. Get your reliability and off-road as high as you can get them.

Later on, the minimum offroad was stipulated to be 35. Then I said right, I can do that. And I bet you I can get the car around Nordschleife faster than 10 minutes. Which would beat the hell out of my new Civic, which, in a sense, would be kind of sad. But anyway.

An hour of tinkering with the £%*&ing restrictions later, I came up with this thing:

StumpyGearing.png (797.08 KiB) Viewed 5359 times

Closeness 35 min with max 2750rpm at 100kph, check

StumpyOffRoad.png (705.96 KiB) Viewed 5359 times

Offroad > 35, check

StumpyNord.png (903.86 KiB) Viewed 5359 times

Does Nordschleife in under 10 minutes, check!

In the next post, I'll post the .lua file, as proof that all the conditions, and my secondary goal, has been met. Therefore, while this car still ought to be placed on the "Cars you don't brag about" thread, really, I'm bragging about this one because it's out of my unusual comfort zone, and I still managed to pass

[HighOctaneLove]

Nice work strop...

I can't wait for the diesel DLC then we can all have a go of getting a diesel van around the 'ring in under 10 minutes!

[strop]

So having been tortured with an insanely slow car that was forced to use chunky offroad tyres, I decided, what is VicVictory not so good at?

Then the lightbulb moment came to me: of course, he's bad at making cars fast What better way to potentially embarrass him by making him tune up an icon? Here we go!

Warning: the following contains an extended parody of several elements of Australian culture, which I'm qualified to do, being Australian. If you don't understand a particular term, chances are, it's uniquely Australian

You are a young, hot-headed and ego-filled Australian import tuner nut who spent way too long annoying your Holden and Ford mates, waxing lyrical about the magic of the Nissan Skyline and how it singlehandedly destroyed the touring car scene when the BNR32 dominated road and track the world around, which is no doubt an even sorer point now that a) the V8 Supercar league had to reopen its doors to all marques to revive interest in it, though strategically keeping it to 4 door saloons so stuff like the Skyline can't get in b) Holden and Ford have decided to pack up and leave Australia for good (because they spent too much time and money building oversized 4 door saloons and trying to out-piss each other in an increasingly irrelevant performance shootout). Something you do not hesitate to point out to them, with gusto.

In fact, your bogan VB swilling Aussie mates get so sick of your apparent Wapanese fanboyism, that they start dissing your beloved Skyline. They're tinny underpowered tin boxes, they said. RB26DETT modded to 1600hp? Bitch please, we have small block Holden V8s busting 2000 on the dyno. REAL grunt, the type that can produce Summernats level burnouts. And so on and so forth. It all comes to a head when you, in an inebriated moment of Asahi-powered overconfidence, declare that you can get your hands on a Skyline and it will smoke all their Holden and Ford shit on the track anyday. Your Holden nut scoffs and says get real, I bet your Skyline can't even beat a Holden SS UTE around the track (and be aware, that thing did a lairy 8:19 on Nordschleife).

So you break into your rainy day savings and shell out 14 grand on a second-hand '00 BNR34. The moment you get it home and you park it in the garage, you get out and take your first proper look at your new acquisition and you nearly cream your pants.

BNR34.png (592.05 KiB) Viewed 5305 times

I mean look at it, it's beautiful.

This is the point when you take it for a proper drive and that unsettling feeling of panic starts to set in. This car's been flogged. Hard. Lots. Well you should have known, after all, who the hell buys at Skyline if they aren't going to drive it hard anyway? But the point is, the engine has a few rattles in it, the tyres are kind of running bare, and the brakes, oh yes the brakes are really suffering, it feels like the brake calipers are made of potato or something, god. There's no way your car's gonna measure up on the track. In fact, right now, it won't even make 9 minutes on Nordschleife.

This is also the point when you remember that as officially as you know, a stock BNR34 should do Nordschleife in 8:28. Which is a lot slower than that SS Ute your mates were talking about earlier.

Time for an FML moment. What do you do? It's not like you're made out of money, you haven't yet finished your mechanic's apprenticeship and while the money's gonna come rolling in eventually, right now you're on Centrelink's Newstart Allowance, and you kind of spend most of your welfare on beer. And weed. And boy mags (and, when nobody's looking, shit tons of manga, because you're Wapanese). And when your mates see how shit your car is, they're going to laugh at you and call you the C word and nobody calls you the C word, but worse than that, they're going to piss all over your car some more and make racist remarks about the Japanese. It's hard being a weeaboo.

Back to the point, you need to figure out how to either a) tune the car on the cheap without your mates noticing, and somehow managing to eke a respectable time out of it b) fuck that, everybody mods these things anyway, besides, how about a little of that NISMO power? Maybe you can pretend you got a V-spec or something.

To sum up: Right now, you've got a BNR34. The RB26DETT (or at least as close as I can get to one when we don't have twin turbo i6) is a little worn. The stock 235/45R17s are somewhat worn, and the 300mm F/280mm R ventilated discs are REALLY worn.

Realistically, you have three options. All of them involve upping the ante and goading your mates into laying down some real dough. With any luck they won't realise that you hope to win the bet, thereby financing your car with their dough, but of course, should you lose that bet, well, some people will pay handsomely for a kidney, right?

RULES:

Under no circumstances are you allowed to change the materials, the dimensions, the valvetrain or the injection of the engine. It would cease to be an RB26DETT if you did.
Unless otherwise stated...

• You are also not allowed to change the layout, or the chassis, or add any vents or grilles, that's too obvious.
• You can't change frame material, that's just way too messy and involved and you don't know how to do that.
• This thing has to be street legal. Keep the volume under 60. And the emissions under 400.
• The engine has to kind of hold together for a few more floggings, so reliability should be above 30.
• This car must always be able to take pump gas, that is, 91RON.
• No negative quality sliders on interior, entertainment or safety!

OPTION A: THE STAGE HOPE-NOBODY-NOTICES-I-CLEARLY-TUNED-THIS-THING MODE

Aim: Get this thing back to its stock performance (In the 8:28s around Nordschleife)
How much you managed to scrimp off your mates: $1000 (or 11748.91 in total costs).
Deadline: 1 week (or 135 production units of working feverishly in the garage after your shift is done)
Modifications:

• No touchy the chassis!
• No time to find a new block, just whack a new turbo and exhaust on it.
• All quality sliders except for aspiration and exhaust must remain at -3. For the aspiration and exhaust tab, you can do whatever you like EXCEPT change exhaust header type.
• You are also allowed to change fuel mix, ignition timing, redline, compression ratio, and cam profile, but nothing else.
• You can adjust space of the gear ratios and final drive only.
• You may replace your wheels with the same dimension wheels of any quality. Different size, and your mates will know!
• You may replace your brakes with the same dimension brakes of any quality. Different size, and your mates will know!
• You may change the angle of that wing, if you like. And you can open up the vents some more, too, but no quality changes.
• You may NOT touch the trim at all.
• You may alter the suspension settings, but you don't have the money to replace it, so it has to stay -3 quality.

Reward: Your friends will still call you a c*** who bought a shitbox Nissan that can't even match a Ute around Nordschleife, but hey, at least you got a Skyline.

OPTION B: THE STAGE MAYBE I CAN PASS THIS OFF AS A V-SPEC

Aim: Beat the damn Ute! (8:19 around Nordschleife)
How much you managed to scrimp off your mates: $3250 (or 14000 in total costs minus two hash browns from Maccas).
Deadline: 2 weeks (or 145 production units of working feverishly in the garage after your shift is done)
Modifications:

• Still no touchy the chassis!
• Now you have a week to shop around for a nice new block and do some restoration on it. All engine quality sliders are fair game.
• Still, you only have free rein on exhaust and turbo, and no changing exhaust header type.
• Again, you are also allowed to change fuel mix, ignition timing, redline, compression ratio, and cam profile, but nothing else.
• You may adjust space of the gear ratios and final drive, and quality of drivetrain.
• You may do whatever you like with the wheels, but no semi-slicks!
• You may do whatever you like with the brakes.
• You may ADD one lip at both ends (or either, take your fancy), and fiddle with the aero, but can NOT add any undertray, or change quality of aero.
• You may take some of the stuffing in the doors out, but can't touch the trim otherwise.
• Time for some new shocks! Do whatever you like with the suspension.

Reward: Your friends will grudgingly accept that your Skyline isn't that shitty after all, and you may get a free crate of nasty beer for your trouble.

OPTION C: THE STAGE NISMO HERE WE GO!

Aim: Get into serious sports car territory (Under 8 minutes around Nordschleife) with nothing more than extra elbow grease.
How much you managed to scrimp off your mates: $3250 (or 14000 in total costs minus two hash browns from Maccas... they're not rich either!)
Deadline: 3 weeks (or 155 production units of working feverishly in the garage after your shift is done)
Modifications:

• The chassis is fair game! You may change suspension and panel material.
• Now you have a 2 weeks to shop around for a nice new block and do some restoration on it. All engine quality sliders are fair game.
• As usual, you only have free rein on exhaust and turbo.
• This time, not only are you allowed to change fuel mix, ignition timing, redline, compression ratio, and cam profile, but also air intake, and throttle body... and you can, if you want, use 95RON, but nothing else.
• You may adjust space of the gear ratios and final drive, and quality of drivetrain.
• You may do whatever you like with the wheels, period.
• You may do whatever you like with the brakes.
• You may ADD one lip at both ends (or either, take your fancy), and do whatever you like with the aero tab.
• You may take some of the stuffing in the doors out, but can't touch the interior, entertainment or safety otherwise.
• Do whatever you like with the suspension. Go JDM on that shit or whatever.

Reward: Your friends will be amazed at your Nismo-like skillz, and are thrilled to ride in a car with proper sports credentials. Your garage gets a minor boost in rep. Your friends don't give you any more shit about being Wapanese, and that is a sweet victory indeed.

Which level will you achieve? Will you shoot for glory, or will you sort of muddle along in mediocrity, or, better yet, fail entirely? What are you waiting for? Go get your Skyline and get tuning!

P.S. Stubby lua has been attached, as proof of completion of previous challenge.

[Manche]

all nice and dandy.... what mods are applied into that Nissan so i can try tune it?

[strop]

felgen's wing set, found bundled with this car and that should be it!

Keeping in mind, of course, that this is VicVictory's challenge, so naturally everybody is welcome to see how they go, but only Vic should post his attempt on this thread first.

[VicVictory]

Wow. That's just downright mean and evil. Lol...

[np1993]

So far the challenges have been awesome!

On a side note, thanks for building a skyline, it was by fluke I built a 3.0L stroker kitted RB26DET engine last week just for kicks.
