    Mikunioz in Australia has been in business since 1985, they offer knowledgable professional service, and answer all questions . Phone or email them for advice . Using HSR's on cars they have developed their own pump nozzles , the pumps are adjustable, but the stock Accelerator pump nozzles are to large, 42's are probably more suited than 45's for 2 lt engines . i have no association with Mikunioz but in contacting them they answered all my queries .
  2. Mikuni Oz ,. Australia is a long term reputable company , with excellent customer service . Phone contact excellent knowledgeable people. They Supply custom accelerator pump nozzles for car use. Most people report flat spots on acceleration , believing it's "lean" try for bigger accelerator pumps . The spray nozzles are "too big" so they developed their own. The guys at Mikunioz have been in The business for decades .

    Input ratio swap

    Aussie bluebird is the same a a Maxima L20B the pintara is truck #3 or 83-10/84 200sx with Ca20, ratio % change = 3.321. 42%. 1.901. 34%. 1.258 20% 1:1. OD 0.838. 16% 215/65/14 tyres 4.625 ratio diff speed @6,500rpm= 1, 31mph 2, 55mph 3, 83mph 4th 105mph 5th 125mph Rpm drop 1-2 3721rpm 2-3 4301rpm 3-4 5171rpm 4-5 5447rpm 4.889ratio diff speed @6,500rpm= 1, 30mph 2, 52mph 3, 79mp 4, 99mph . 5. 118mph Rpm drop between gears is the same with any ratio diff now all I need is enough power to achieve it ! ! ! the original 3rd gear 1.36 is a big jump into 4th 27% 6500-4745 swapped input 3rd gear of 1.258 into 4th is 20% 6500-5171 this gear set has a big jump into 2nd although it is 42% that's the same as the standard boxes , a 4.8 Ratio diff will help get off the line

    Input ratio swap

    Pintara Ca20 first gear 33/14 = 2.357 X 1.52 = 3.592 Bluey(910) first gear 33/14 = 2.357 X 1.409 = 3.321 pintara Ca20 5th.OD gear. 21/39 = 0.538 X 1.524. = 0.82 OD pintara Ca20 5th OD gear. 21/39 = 0.538 X 1.409. = 0.758 OD :( Bluey(910). 5th OD gear. 22/37 = 0.595 X 1.409. = 0.838 OD :) My 100mph mongrel box swap input from 1.524 with truck #3 / Ca20 > 1.409 should have the following ratio's First. 2nd. 3rd. 4th. 5th OD 3.321. 1.902. 1.258. 1:1. 0.758 OD Or if you can keep bluey (910) OD gears 3.321. 1.902. 1.258. 1:1. 0.838 OD 0.775 OD was typo or bad math 25/28 tooth count for 1.361 3rd gear as pintara box still in car with this box I hope to get close to target under 14 sec 1/4 mile @ 95+mph 4.625 diff, L20B in 521 and a bit of motorkana please advise if I can do this swap ? 5th OD gears swappable?
  5. I have a L20B engine and gearbox from a 910 a (Aussie bluebird ). i want to swap a pintara gearbox into L20B case/ bell housing 910/bluebird gearbox Input 22/31 1.409 ratio 3.321 2.077. 1.308. 1:1 0.838 Pintara gearbox. input 21/33 1.524 ratio 3.592. 2.057 1.361 1:1 0.852 if I keep input shaft and counter gear 1.409 22/31 in 910 bluey case and change too the pintara gearset Change the selector from 14mm to a 16mm selector socket too suit 910 case i hope to end up with input 22/31 1.409 ratio 3.321. 1.901. 1.257 1:1 0.775 ...... 42%. 34%. 20% 22.5% i only have these 2 gearboxes , the bluey 910 box is stuffed but the input and counter gear are good So will this work? not the standard mongrel box I want, but 280zx boxes are hard to find here in OZ and I don't want to spend extra $$$$. This is going in a 521 with a 4.625 diff so the big 1-2 gap 42% give a useable 1st "hard launch" and hold to redline before changing too 2nd :) better to have big gap at lower speed and ratio's closing up from there any thoughts , idea's , comment's ? Recommendations appreciated Tony22

    520 front overriders

    rare Datsun indeed then. Worthwhile project appears mostly complete interior is good maybe a bit overpriced , but if had had the $ I would consider it ,restore to original, it would be worth more does dash appear original with tachometer and side gauges? Very sporty thanks for the info I'm getting off topic probably should have this in the 320 section . im am in Colac Victoria the 520 with overriders or 410 bumper is one of the fellows Utes I'm buying sons 521 project alas the 521 does not have a tub and they are very had to come buy ,although not impossible to find and priced accordingly. I will get some pics up of 521 project when I get to see it again . Pits been in primer for a couple of years so will need primer stripped and reapplied . Other wise rust will come through the paint it is the reason I'm hesitant .

    Quoting ad "around 1,000 made " would that be just for Australia or worldwide? if so it is a rare survivor

    It appears bumper isn't original too truck . Old farmer Joe must have bent the original and replaced it ,the brackets just look like a farmer has made his own mounts .They aren't factory looking at all. Who knows what happened on the farm over almost 50 years . But the front panels seem straight and untouched like the rest of the truck . More than likely bumper was replaced with a 410 bumper. Just when you think you have found something rare , thanks everyone for there input ,

    They must be a rare accessory if no one else on this forum has ever seen 520 overriders 1967 520 Australian delivered i will ask previous owner if the bumper is original to the "ute". Truck I mean , twin headlight in 1967 520 but I can stand corrected
