  1. So using a 6AL-2 system would be the go then? http://www.msdperformance.com/Products/Ignitions/6530_-_MSD_Digital_Programmable_6AL-2.aspx Then remove the mechanical and vaccum advances? Then wire in the 6AL2 as per this manual: file:///C:/Users/RemoteService/Downloads/6530.pdf using wiring of page 6 figure 3 (at the top)? Does this make sense and is the right way to play?
  2. So the engine specs are: HEAD WORK: - changed combustion chamber profile to be even instead of that silly peanut shape - massively oversized valves - ported head - pretty big - Comp ratio is 12.5:1 static - around 8.7:1 dynamic Cam - Tighes 413 (259 @ 50" - massive) Motor - fully balanced bottom end GSXR1100 motor cycle pistons and H Beam aftermarket 4AGE rods Carbs - Twin webber 40mm (also have DHLA45's if needed) Still road registered (LOL) but more for hillclimbs and whatever
  3. Thanks Guys, I'll pull it down tonight to see what we can do about locking it up. What is your preference for Coil and mappable ignition controller?
  4. Ok, so searched for the last 30 minutes with little success. I'm building my 3k now, and the new 5k dizzy i just bought from Golbys has 2 vacuum ports. What the hell am I meant to do with these? Hook one up (and if so - which one) or both? I've heard that the curve on these is pretty shit > which is ok, its for a race motor, so hopefully it will be spending its life north of 4000rpm anyway, but is it worth locking it? Thanks in advance for your help matt
  5. So that 3k I bought purely as a runner to get it regod? Turned out to be a fully balanced bottom end, polished rods and what looks to be lightened pistons. So I decided to put the head and cam on it as well as the flywheel, shit does this thing move... 10,000rpm and an absolute ball with the dcoe40 which we fitted just yesterday... I'll put up a video, 5000-8500 happens in a flash in first gear. Really needs a 4.5 or better diff with 5speed...
  6. So I've been playing a little bit lately. It turns out that this little 3K i bought and stuck in the car for ReGO is the perfect bore size and Everything else. So the Flywheel is off getting lightened, Gearbox is getting resealed, and i will finish polishing the crank this weekend and get the whole assembly Balanced this weekend. I have the GSXR rings, wrist pins clips and what not on order currently, so hopefully that will only be a short amount of time before they are here, and we can slap this thing back together! In the meantime, we've started on the Chassis side of things... Building a race car - even on a tight budget - is not a 'cheap exercise. SO at the moment, we're trying to gain speed the slowest but cheapest way possible - remove weight. So the attachments are just a small idea of what we're up to. All the interior is gone, and the seam welding should start this weekend also as all the sound deadening is gone. Slowly but surely, we're getting there!
  7. Short Answer; I want to track this thing. I am building a 3K engine with GSXR pistons, 4AGE forged rods, balanced Crank, and eventually, Turbo. game plan is to rev the thing to 10,000+ rpm. I currently have the engine out, and doing all the lightening to the chassis + seem welding, just wanted to know if i could get away with it, as i have a set here from my AW11 (that has 15x10s on it)... Now you can get Hosier 275/35/15 tyres, and in a little tiny chassis like that, i think with the little 3K, you'd never have to brake!!! Mid corner speed = fast lap times.
  8. Theres a Dude at the end of my street that sells them on eBay (they are grey) and they are a total PIECE OF SHIT... I had to spend like 6 hours to make them actually seal down on the head. The flange is too far away from the bolts, he has welded the runners all the way to the edge of the flange so there is NO flat surface to use to clamp the ʞ©$ɟer to the head, Then, Ext from cylinder 3 comes out at a small angle that means getting a bolt in there is actually a physical impossibility... In the end, i had to heli-coil the head, fit undersized studs, Have 2.5mm thick washers made up to go under the 10mm flanged nuts (small stud size) then had to grind them away at certain points to clear the welds to it would actually touch the flat flange section. After all that, 3 still leaks a very minute amount... :down: So irritated (if you cannot tell!)
  9. Hi Guys, Done a bit of research and have seen that people have fitted 15X9 with zero offset and have gotten away with it, however i'm trying to get 10's on there... I've got flares to cover the width outside the guards, so I'm more concerned with what offset i'll need to clear the suspension. Can someone help me out? THanks matt
  10. How! That thing looks decently fast! Obviously you've got that cam issue sorted out??
  11. I'd love to have another crack. Great couple of mate bonding weeks sorting the car, then an unreal weekend racing with a bunch of like minded people. I googled obviously, but didn't see anything like it in aus, was just wondering if any of you knew of anything...
  12. Hey guys, do any of you know if this has ever been attempted in australia? It looks like an awesome concept, be a great weekend with a bunch of friends. I've raced one in the states when I lived there, but that was a while ago... Anyway, any news would be great. Thanks Matt
  13. HI Altezza; I never rebuilt these carbies, but did change a few of the upfront settings to new jets (what i could purchase anyway...) Now that i think about it, the mis-behaving carby did look to have a little water damage inside. I might take her apart and hopefully i'll find a little air channel or something blocked. If that don't work, i will do as you suggest, swap everything and work backwards. Thanks mate! :)
  14. Hi guys, running a pretty hot 3k, with twin dhla45s on it. I know they are too big (plan is for 10,000+rpm) but these are the settings: 34mm chokes 135 mains 7772.7 emulsions 190 air correctors 55 idle set, 33 pump jet Theres a big flat spot on jet change over, but the main problem is that one carby is running MASSIVELY rich bottom end, so much so that within 10ks driving, the plugs are black. All the jets seem to be the same, emullsions clean, floats the same. Is there something that I'm missing? Thanks in advance. Matt
  15. Let me be the first to say: HOLLY SHIT! This thing looks like it will be serious!
