  1. Had a shitty old 4 door KP starlet... rusty as fuck, steel wheels, mismatched panel colours, yada yada.

    And yet the amount of people doing the 'do a burnout' type signal thing with their hands, or giving the thumbs up, or whatever... lol.

    Never realised that so many knew what a powerhouse a 4K is.

  2. Although in saying all of this, I do think that some cars are 'copies' or.... appealing to an established target audience if you want to be diplomatic. :P

    the early 80s carina sedans are a copy of the cortina IMO...

    Samish weight, samish drivetrain etc, samish looks.

    Hell, even the names are similar! Take the T out of cortina and do the maths :P

    But then again, perhaps toyota needed a sedan of that shape/size/proportions, and already had the overall design sorted... but then adapted a simlar name to cortina, and other similar design cues so people would associate it with another car of that size/weight/etc that was already established, to try and break into an existing market.

  3. I think that some things arent styling cues so much as... design practicalities.

    "Alright guys we want a 2 seater sports car, and we've got this straight six motor that we wanna use."

    "Well, gonna need a bulge in the bonnet to fit that motor and keep an overall low bonnet line"

    "Gonna have to put the driver and passenger far back to get a good weight balance"

    "Gonna have to slope the rear down in a manner which is aerodynamic, fitting all of the above"

    etc etc

    And voila, you have a stack of cars that have the same 'styling cues' which arent necessarily 'copied', or coincidental, but just a prerequisite of comptetently designing a car of a certain configuration.

    Fill in the cracks with whatever's in vogue at the time, and you're gonna get quite a few different cars that look similarish.

    It's even worse for modern cars, because there's so many more rules and regulations to adhere to.

    Car must be as aerodynamic as possible for fuel efficiency. (which majorly affects the shape)

    Car must not decapitate pedestrians. (boo)

    Car must be fitted with XYZ safety features.

    Car must not belch flames.

    etc etc.

    And personally I think that the E type looks horrible, and the 240Z looks freaken sweet.

  4. Seriously, get some bunnings warehouse general purpose paint stripper.

    It is the best shit ever, took my car back to bare metal right before my eyes, and left it perfectly smooth underneath.

    And oddly enough, automotive paint stripper that I had used previously made my panels go rusty looking, and smeared all the paint into goo.

    Bunnings warehouse paint stripper made my paint almost explode off, and was super easy to clean up, and obviously wasnt water based, or whatever.

    It's one of those "Christ I cant believe I wasted so much time up to this point with a wire brush" kind of things :P

    Assuming Fiat paint is anything like Toyota paint, that is.

  5. I skate out west Auckland pretty much every day that it's not raining.

    Mostly Tepai mucking around in the snake run, sometimes marlborough park, and the odd lynnfield bowl mission if I havent been mugged in a while. :lol:

    CBF going anywhere else usually, too old and creaky for doing much of much.

    A cane around the bowland a bigspin flip or two here and there and I'm happy. 8)

  6. If you're gonna ditch the VVTI (and therefore most of your powerband) dont bother with a beams motor.

    May as well just use the gen 3, much easier to run an aftermarket ECU with.

    The beams motor has a table just like fuel or ignition timing that it references to, it changes the cam angles based on rpms and AFM signal.... so it's always making the best possible torque, even at part or light throttle.

    There's no point adding quads (presumably for a power gain) and then throwing away a shite load of power in doing so.

  7. Everyone on the internet seems to say that it makes your manifold rust etc...

    But when I had heat wrap start to fall off mine and I pulled it off, it looked mint underneath, and rusty near the flange where there was never any wrap.

    Cant say I noticed a power difference though, but that's not why I'd fit it, personally. (or HPC)

  8. Nothing wrong with the gen 3 motor IMO.

    If you had a gen 2, I'd say "ditch it" but gen 3 aint so bad, fixed a lot of the gen 2 problems.

    money spent on your gen 3 to get it up to beams hp wouldve got you one easy.

    Agreed, pick one up for $1200 if you keep an eye out.

    beams is bang for buck n/a wise just fail in the heavy arse altezza shit

    Agreed. my beams car was heaps of fun, was just over a tonne.

    A 2 litre NA in a 1350-1400KG car, ugh, why. :( (well, so people can pillage them for motors etc I guess :P )

  9. Two breather lines, 1 in and 1 out!

    The air gets sucked in with one pipe, from before throttle body/vaccum.

    Then into crank case, then out of crank case (via other line) and then to vaccum/intake manifold to be burnt by the engine.

    There's a 1 way valve on the one that needs to go to vaccum, (put catch can in/on this one) and the other one just needs filtered air.

    Or, dont put a filter on it at all if you're rugged. :P

    I'm not sure how much air flows through, but if you're using an AFM it might be wise to have it plumbed in I guess.

    P.S. What does the vaccum pump setup do?

  10. Hahah, same! I didnt know there was a movie, but I sure as hell remember playing that game.

    When you come into the pits and filling up your car, guy says "Say when" and you click the "when" button.

    Aaaahhh, memories. :D

  11. To put it more simply, if it's tuned for resonance (to make more power/torque) at X rpm, then at some other rpm, the resonance will be working to reduce power.A motor tuned for resonance will have a peaky rather than broad torque curve

    Well most engines seem to use intake lengths to give a mid range boost, perhaps where there would have been a slump otherwise. Tuning resonance to occur around peak hp/torque will probably make it more peaky, but you could probably tune for an rpm band away from this, to give it a broader powerband.

    Either way, most people who make the intake runner length a lot shorter than factory end up losing a big chunk of the powerband. (In modernish NA applications anyway)

  12. I've been wondering about the affects of having VVTI on the intake side, and resonance tuning.

    For example where the pressure wave might hit 'too early' you could advance the cam timing so it's letting air in, at that point. And vice versa for a 'late' pulse. And then the opposite, for when you're in a resonance 'trough'.

    Although there might be less overall gain from that then there would by having the cam in the 'right' place to suit that RPM etc anyway.

  13. If I can get the overall runner length to be about 320mm:

    "For 3rd harmonic, RPM range is from 7007 to 8008 with a pulse strength of 7 percent

    For 4th harmonic, RPM range is from 5463 to 6109 with a pulse strength of 4 percent "

    So reversion pulse FTW, so long as I can get that sort of overall runner length, if not longer. (wont be able to fit much longer than that though)
