luvemfast Posted February 22, 2013 Posted February 22, 2013 As title states. I'm after a set of 37 dia chokes for my triple Mikuni's. Lower control arms to cut and modify to give adjustable camber. Also, the steering adjustment nuts, with left and right threads. Going to modify to suit extra track width. They are M18, but what pitch are they? Anyone help? Thanks, Simon Quote
1600dave Posted February 26, 2013 Posted February 26, 2013 Rack and pinion or steering box style front end ? Everything below is based on steering-box style front end, I'm not sure if rack and pinion front ends are the same ? How are you making the adjustable LCA's ? If you're welding a length of threaded rod, etc, with a rose joint or similar as the pivot, I have a pair of control arms with the inner end cut off - total length is just under 300mm. I did a "cut'n'shut" on 2 pairs to give one lengthened (but fixed length) pair. The bits in the pic are the leftovers. Yours for the cost of postage from Newcastle, NSW if you think you can make use of them. 200B (and maybe 240K, they take the same ball joint) LCA's are identical if that makes it easier to find - I have 200B and 280ZX and can neither see nor measure any difference between them. I also have the correct taps (including the lefthand thread one that cost me a touch over $100) for making the longer tie-rod bits and could make some for you need if you get desperate (or could even post the taps down if you want a lend of them - they are pretty exxy for a one-off job).). Anyway, let me know if I can be of any help Quote
luvemfast Posted February 26, 2013 Author Posted February 26, 2013 Thanks dave, Those LCA's look different, visually. They dont have a stregthening gusset attached to the bottom. Maybe just a 280ZX thing due to extra weight? Here's the bit I have the taps for. Was thinking of 25-30mm longer to be honest. But thanks, will keep your offer in mind. Have you got pics of the bits you made? Can you verify thread, is it M18 x 2mm? Quote
luvemfast Posted February 26, 2013 Author Posted February 26, 2013 I've got the drag link set up. I think they are the same as 1600's? Also. How far out did you move yours? How did you do caster as well? Quote
1600dave Posted February 26, 2013 Posted February 26, 2013 Hmm, interesting. The leftover bits in the pic are from a 280ZX (I thought) Pretty sure I used the 200B outer piece and the 280ZX inner piece Perhaps my memory fails me. Mine are re-inforced internally with a bit of 19mm or thereabouts RHS running the length of the LCA, thought it was a good idea given the extra length. I'll see if I can find a pic of the adjusters - I made them from a bit of hex bar, turned down so that it was round with only a 10mm "hex" bit left in the centre so I can use a spanner to adjust them rather than a pair of stillsons like with the factory bits So, turned down the outside, drilled and bored internally, tapped either end, then used a slitting saw blade in the lathe chuck (and mounted the job on the lathe cross slide) to cut the slit down the side. Tap is M18 X 1.5 incidentally. Quote
1600dave Posted February 26, 2013 Posted February 26, 2013 I extended the LCA's by 20mm per side. Logic behind that is that the Datsport handling kit for a 1600 uses a standard 200B front x-member and LCA's. A 180B SSS is 40mm wider between the strut towers, so adding 20mm per side into the LCA's gets the setup back to the Datsport 1600 arrangement. Is this the ideal suspension geometry ?? Don't know, but I reckon Datsport know more about suspension setup than I do, Then again, maybe they do it to save the extra hassle / expense of modifying stuff ? If I went for more than 20mm (more camber) I would have had to consider the effect of pushing the wheel / tyre outwards, possibly fouling on the guard - I had this issue on my track 1600 which was extended by 40mm per side. I also run adjustable strut tops on the 180B (not on the 1600), so I'll get some adjustment there. I haven''t got the 180B SSS finished yet, but the plan is to manufacture new custom radius rod mounting brackets that will position the pivot point of the radius rod in a direct line with the pivot point of the LCA. The idea is that this will avoid changes in geometry as the wheel moves through its suspension travel. Caster is accounted for by custom (adjustable) radius rods. On my 1600, I just spaced the radius rod back a little with washers to remove some of the added caster, and ran with some added caster (not ideal, the LCA inner rubber bushes are a little distorted, hasn't caused me any grief yet though). Sway bar is also an issue - on the 1600 I used a 2" length of steel bar to take up the difference (one hole each end, one end bolted to swaybar, other end attached to sway bar link). Again, maybe not ideal, but it seems to work. The 180B will have custom adjustable sway bar, so not an issue. The pic below shows the extended ones. Whereabouts is the extra gusset on your 280ZX LCA's ? Quote
Roberto Posted March 4, 2013 Posted March 4, 2013 I'm after a set of 37 dia chokes for my triple Mikuni's. Anyone help? Thanks, Simon Hi Simon, I have 37mm mikuni chokes. Why do you want to go smaller? Quote
luvemfast Posted March 4, 2013 Author Posted March 4, 2013 Hi Simon, I have 37mm mikuni chokes. Why do you want to go smaller? For 44PHH? Peter thinks it'll give better mid range performance. Compared to my 40 chokes, they'll be better suited to high. But I guess the dyno will tell How much you want for them? Quote
Roberto Posted March 4, 2013 Posted March 4, 2013 Yes for 44phh. Not sure on price. Maybe we can trade parts? Quote
luvemfast Posted March 4, 2013 Author Posted March 4, 2013 Yes for 44phh. Not sure on price. Maybe we can trade parts? Lol What you after? Quote
Roberto Posted March 4, 2013 Posted March 4, 2013 Lol What you after? 4.4 LSD, Wilwoods How about I send them to you and you try them, and see how you go. If you like the results, you can either have them for $100 or give me your 40mm. If you think you are losing to much top end, send them back. How does that sound? Quote

Gordo Posted March 5, 2013 Posted March 5, 2013 That's a great deal, Roberto is looking after you Simon, you try , then you buy. What would the postage be for a slab? Quote
luvemfast Posted March 5, 2013 Author Posted March 5, 2013 Yes it would be a good deal.......... If Roberto could count! Or read! Or count and read! Nah. He thought they were 37's when they were 34's :'( Quote
NZeder Posted December 9, 2013 Posted December 9, 2013 Opening up this old thread again. Did you find any 37mm chokes Simon? I am looking for a set as my 41mm in my Mikuni's are bit large too Quote
luvemfast Posted December 9, 2013 Author Posted December 9, 2013 Stopped trying as i initially wanted them before hitting the dyno. I've got other things to do and I'm pretty happy with the mid to low end anyway. Quote
