Due to it being the Only Hatch Skyline to my Knowledge(and i want a Hatch) i have recently Came Across one that i like in perticular But Before Buying i was Curious If anyone Knew My Options My plans where as Follows:

L24 injected conversion To --- Any body know a Simple Conversion with 150 BHp easily obtainable Torque a Must.

the R31 to s13 coilover setup is this Just as Easy to do with the R30 to s13?

some Serious Camber How is this Obtainable with this Car?

Machine The Setup For the Castor Rods So that with added washed/spaces comes More CAMBER!

Bucket seats, remove Rear Seats and all Temp Gauges Neccasary

Further Forwared Positining of Lights With Better Globes.

Respray.

some R33 Tailights (rice i know *hangs head in shame*)

ANd watever else Comes To mind.

any ideas Are Welcome and Help Is also Very welcome i dono much about the Interchangability Of the R30 heard there similar To the Laurel

I have one of these myself. I'll fill you in on what I know, from having done it, having heard about it, or having head about / done on another model Nissan.

Power Up - fit a R31 X-member, then any of the RB-series engines will fit. But that will require a new gearbox and modified tail shaft. Alternatively, an upgrade to a L28 (280ZX) engine, upgraded camshaft + extractors, might come close to what you are chasing.

Camber - By relocating the pickup point of the lower control arm, you can possibly crank some camber into it (but probably not "serious" camber). Others have been known to bend the strut at the stub axle connection (I think that's it, but never witnessed it)

You won't get more camber by changing the castor. If you fit LJ Torana castor rods IIRC, you effectively get adjustable castor rods, because the threaded section is too long.

Hope that gives you some ideas.

mate, some of the things your looking to do are an ask, unless you have $$$,

Engine swap with torque?? L24et, L28et, rb30et perhaps but the rb30 may site too high to close the bonnet, you may want to look into a vg30et ($$$) or a rb30de if you don't mind N/A..

Camber, correct adj strut tops for an r30 are a great start plenty of camber there, depending on the amount of chamber you are looking for and the tyre budget you have. you can always change other components later.

seats you can transfer the hr31 seats to the r30 rails but they will sit higher than normal, $250 will get you a brand new seat rail that is lowered and you can mount any aftermarket seat on them, mine arrives in the next few weeks for japan, you can get a recaro one ordered at autobarn for $400.

the rest your asking about are things you don't need advice on, removing the rear seat is what, undo bolts and remove.

the r33 lights ??? your better off looking for a set of HR30 hotplates or DR30 ones as it would cost more to convert the wiring and fit the r33's than its worth, couple of hundred at the most to get a set of DR30 tail lights from japan, or even here, that are in 100% A1 condition, then you just put them in no mucking about..

heres a link to a set for sale on ebay

i think you'll find the laurel is more r31 than r30 if anything..

Need more positive castor not statric negative camber , that way you get the negative camber only when you need it ie when you turn the wheel . Much cheaper , much more effective . Ask Stu Wilkins to get some real ones made from the right grade steel , substitutes have been known to break and when they do its curtains in no uncertain terms .

BMW started this caster trend with E30's which were the M3's raced out here many years ago - it works .

Can you pM me more On this castor Info, where to get them made up, how Much castor they give and so on and so forth?

Made from 60T steel whatever that is and fitted to any serious Datsun rally car .

When you increase positive caster both wheels assume a camber in the correct direction . Outside wheel goes negative and inside goes positive which is what you want . What happens when the wallys use heaps of static negative camber and little positive caster is the inside wheel (relative to the corner) stays partially negative , so only about 1/3 of the available tread width is on the deck and not using its full grip potential . This shows up as unevenly worn tyres on the inside because when the outside tyres grip threshold is reached the inside tyre is dragged across the tarmack in understeer mode .

I use 1/2 deg negative camber and ~ 6 deg positive caster , I have 205/55/16 front tyres on my DR30 and 225/50/16 rear tyres and the front easily outgrips the rear . The limit of positive caster is how heavy you can stand the steering being . At 6 mine is reasonable with pwr steer but not so hot for armstrong power steer !

Most modern cars use lots of positive caster which is why they have neutral or even positive static camber and they don't understeer off the road like the old dinosaurs did with positive camber . Easy fix this because you don't need the dramas of adjustable spherical bearing strut tops just the adjustable caster rods and a wheel alignment . Turn in is brilliant for an early 80's car . Also have the toe set to 0 ie no in or out . Noltec or nolathane caster rod bushes are good as well .

Cheers A .

A,

Stu Wilkins doesn't have any, cause I have had them on order foir months and months, but they are coming he assures me.

I will post when I know they're available and polyurethane bushes are a must with his style of adjustable caster bar. Stu's castor bars are about $180.00 pair.

For interest, I can get chrome plated adjustable caster bars made, special order for about $350.00 pair, same as attachment, like Jenesis does in Japan.

I can do these bars for a bit better but would need about 6 pairs on firm order if interested.

    • Yeah, that's fine**. But the numbers you came up with are just wrong. Try it for yourself. Put in any voltage from the possible range and see what result you get. You get nonsense. ** When I say "fine", I mean, it's still shit. The very simple linear formula (slope & intercept) is shit for a sensor with a non-linear response. This is the curve, from your data above. Look at the CURVE! It's only really linear between about 30 and 90 °C. And if you used only that range to define a curve, it would be great. But you would go more and more wrong as you went to higher temps. And that is why the slope & intercept found when you use 50 and 150 as the end points is so bad halfway between those points. The real curve is a long way below the linear curve which just zips straight between the end points, like this one. You could probably use the same slope and a lower intercept, to move that straight line down, and spread the error out. But you would 5-10°C off in a lot of places. You'd need to say what temperature range you really wanted to be most right - say, 100 to 130, and plop the line closest to teh real curve in that region, which would make it quite wrong down at the lower temperatures. Let me just say that HPTuners are not being realistic in only allowing for a simple linear curve. 
    • I feel I should re-iterate. The above picture is the only option available in the software and the blurb from HP Tuners I quoted earlier is the only way to add data to it and that's the description they offer as to how to figure it out. The only fields available is the blank box after (Input/ ) and the box right before = Output. Those are the only numbers that can be entered.
    • No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.
    • God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.
    • Nah, that is hella wrong. If I do a simple linear between 150°C (0.407v) and 50°C (2.98v) I get the formula Temperature = -38.8651*voltage + 165.8181 It is perfectly correct at 50 and 150, but it is as much as 20° out in the region of 110°C, because the actual data is significantly non-linear there. It is no more than 4° out down at the lowest temperatures, but is is seriously shit almost everywhere. I cannot believe that the instruction is to do a 2 point linear fit. I would say the method I used previously would have to be better.
