listen out for Steve's comment at the end

noobie attempt at GroPro. done on the Ghost circuit

great day, definitely up for more. will remember to bring second set of tires next time though.

here's the dynograph. only engine mods are intake filter and exhaust system something tells me that the factory power stated at 280hp at the flywheel is a lie.

yeah got a slip i'll take a photo or scan it, it was 447ft/lbs of torque. 70 shy of sloans 340 something kw gtr. not bad for an na car.

hell yeah, i was just going to put a rb26 in it when the ca original went but really wanted something different. but after it's all been said and done. I'm really glad i did this conversion, i really can't get enough of how this car drives now, the chassis has come alive. unlike the turbo it's all up to my right foot and i love that.

the 450sx now has a digital climate control from a type x, we needed to rewire the 3 plugs for the analog one in to 2 plugs for the digital one. that and it's running close to 19 degrees of timing now, it was running 17 degrees factory... seems a little hi but apparently the factory setting are 15 +/- 2 so 17degrees is the limit so it works. the question is should i put cams in it?

turns out I'm an idiot, the balancer was made to sit spaced out from the engine block. so it does line up there just will be an air cap of an inch between the engine and the start of the balancer. crisis over.

turns out that Ross tuffbond balancer i got made is a $900 paper weight. its not even close. the standard balancers have 3 pulleys i needed the second pulley only as i only run a water pump and alternator of the same pulley. they made it with the first pulley and then it's the width of the second, so nothing lines up. not happy again, why is good help too hard to find! it probably even won't bolt on, 7 months for a balancer that they just winged. really angry!!!

yes vh45 are strong and timing chains a problem, but for boosted v8 you can't go past a vh41, they have double row timing chains and rev out more but still tough as nail internals. they race them in new Zealand, all they do is replace valve springs and retainers, big cams and rev them to 9000 rpm to make 500 hp naturally aspirated.

the 1uz only make power with boost and won't get as far with fewer mods like a vq35. this some what the same with vh's they make considerable power with little to no mods but there's very little aftermarket support. it's up to application. I'd stay with your vq35 idea.

yeah engine looks a bit crowded, the result of putting that huge filter in is staggering. I've seen a few posts on other forums in the US complaining that the vh45 power band flat lines above 5000 rpm. I had the same issue, a massive decline in the rate of acceleration. apparently a 12in long 6in round filter does the trick. who would of thought. now we just have put an air box around it.................some how. on another note, Sean said me he talked to the BMC filter guy at the stand at super-lap on Saturday, and told him his filters suck . I wonder how that went down. they said the biggest enclosed air filter they make only has a 100mm insert.

sweet cruise on my birthday. I'm in if the 450sx VH45DE 4.5Litre V8 Double overhead cam Electronic fuel injection, no grip in 1st and 2nd failboat is on the road again by then.

about 7 months ago i hit up ross tuffbond to make a custom balancer and was told it would take 6 weeks, the six week came i rang up and was told haven't had time. I gave up, and completely forgot about it, thinking it was never going to happen. well i got a call last week and this was apparently just finished!

i think I'll have too start borrowing peoples wheels, and seeing what fits. trial and error, i do know that +20 17*9.5 hit on the suspension. but the caliper clearance was good.

hope someone has info for rim offset for the front of a 180sx with R32 v-spec brembo's. has anyone done this before? would love to test fit a 17*8 +40 or +45. the rears are sorted, were extensively rolled previously for +6 watanabes. this seems like it might be easier to just put wide guards on the front and buy some GTR spec wheels, but i hate the fiberglass. what are peoples thoughts?

mono constructed is the modern way to make car chassis, it's dual constructed if its body can detach from the rails, like model t ford. unless your making a hot rod? at least i think that's what they mean.

they are, when i was doing the research in to it for 450sx i found that the maximum boost-able engine size is just over 4.5 ltrs for a s13. i believe it's 60 cc within the range. these figures were calculated using the weight of 1140kg stated as the factory weight times the factor of 4.82 for na and 4.0 for boosted. from the following link. the ADR limits are slightly different. so the maximum turbo or supercharged engine in a 180sx can be 4560cc and 5494cc for naturally aspirated. so imagine the engine that will able to go in a 1500kg skyline. http://www.rta.nsw.gov.au/registration/downloads/vsi/vsi_06_-_guidelines_for_light_vehicle_modifications_nov_2007.pdf

it's been on the road.......for a month and a half before clutch problems. I'm up for another bogan cruise if you are. bring on the mullets wigs! i don't need'em, wouldn't you have a set on the r33 already anyway. aren't r33 gts-t's pretty much the same as non v-spec r32 gtrs?

the power-fc manual I've seen, says that it uses the oxygen sensors to modify the air-fuel ratio to achieve the target in the injection map. it does give a correction value but the power-fc will modify the correction if it moves and change the inj pulse width correction till it matches the map again. you should deactivate oxy feedback when tuning. your right in saying that it displays what the map says it should be. an example is if you were running nitrous. nitrous is an oxygenated molecule when you run it in a car the bulk of the oxygen that the engine uses for combustion comes from the fuel not the air intake, which several is times faster in reaction time, which why the same principle is used in explosives. you can't map for oxygen that no sensor other than the oxy sensor will see. which is why it must modify the correction values instead. in a perfect would it will never need it but with fuel stations putting all kinds of stuff in fuel to make it cheaper, it can come in handy.

your seeing the difference because the afr on the pfc is worked out using engine sensors (i.e. the oxygen sensors) the power-fc also estimates using the oxy sensors so it isn't as accurate as a wideband. the wide-band has cat convertor and exhaust mufflers and a lot more time for the continued chemical reaction before exhaust gases get to the wide-band. true air-fuel should be done at the exhaust ports, but good luck doing that outside a car manufacture. still you can get really good results doing it with a wide-band, tuners have been doing it for years. trust the wide-band. can you really get a wideband that can be plugged in to the datalogit, that's awesome. who needs a tuner!

bought it brand new from rocket industries, the turbo only saw a month of use until the ca18 spun a bearing. no longer needed as i have a naturally aspirated car. it's a GT2871R with a .64 rear housing rated at 380hp. perfect for an SR. any inquiries e-mail me at [email protected] or pm me.

yes, yes i do know them. you need them?

yeah about wheels.............

450sx now with brembos
