kitchnz Posted July 29, 2013 Report Share Posted July 29, 2013 Hi from New Zealand fellow Datsun-a-holics So here’s a build thread on my 1200 coupe, for those that are interestedI have been building this car for the last 5 years, been a bit of a labour of love, have had a few distractions with other cars, projects and the likes. But finally getting somewhere at last, and am hoping to have finished and on the road end of this year. I brought this about 5 years ago, from a guy who rallies Datsun 1200’s. This car was a spare ‘shell’ he acquired, but as it was 95% complete & original, with live registration and plates, he on-sold it to me, as it was too good to cut up for spare panels.Here are a couple of photos below, of when I brought it June 2007.I had it fully sodium blasted inside, outside and upside down, to show all the sins, and coated in epoxy primer, while it sat for a while.In typical 1200 fashion it needed quite a bit of rust repairs. Luckily all the original plastics and interior are in pretty much faultless condition (for a 40+ year old car at least!) not a mark on the dash, got some solid door cards, and all plastics are there and in real good nic.I decided that JDM type look is the go, with upgraded suspension, brakes & diff. I don’t want the big flared guard look, as want it to look like a cool road car rather than a full circuit car.After much deliberation, and ideas, I decided to stick to A series running. Each to their own, but the Twin cam turbo Nissan repower is just not my cup of tea (and getting pretty common over this way), I love the sound of a push rod A series engine revving, and I love the fact that anyone (including me) can find your way around an A series motor. I also love the lightweight nimble handling car that is associated with using A series motor, ie 700kg and 120hp can still be a lot of fun!After some youtube surfing, I fell in love with the sound of ITB’s so decided to go to what turned out to be a time and money consuming task of developing my own custom EFI / ITB setup. The car was out at my mates resto shop for a good proportion of 2011 having every ounce of rust removed, new custom sills made and fitted, new custom rear wheel arches, and general body repairs and tidy up. Here are a few selected pic’s of the body restoration.Essentially it just needs the front doors rust repaired, and final body fill, and few wee imperfections to sort out, then its ready for paint. 4 Quote Link to comment

kitchnz Posted July 29, 2013 Author Report Share Posted July 29, 2013 So its gettting close now. Need to get drivshaft shortened & few issues with brakes (leaks) sorted, install clutch cable then its basically driveable. Hopefully next month it will be out for final paintwork, I can then get on with final fitout of glass, rubbers & lights. All going well (and time & funds permitting) it will be on the road for Xmas :) Finally got my custom engine setup running, after years of efforts! Hope you guys like the direction I have taken, and my 'take' on a JDM Datsun , with a bit of old vs new in the engine area and the likes Quote Link to comment

kitchnz Posted July 30, 2013 Author Report Share Posted July 30, 2013 When I post up in a few posts like summarizing the build, it looks pretty straight forward..... But it has taken a huge amount of energy and time & $ I assure you! I do everything I can myself, as far as researching, sourcing and installing components / fitout. I just sub out the panel & paint, and any welding works. Here are some pics of some of my sideline projects I have had over last few years, as every now and again I impulse buy a Datsun.... Usually personalize it , cruise in it then sell it, and try and get back on to concentrating on the coupe. Each picture represents a purchase that just about cost me my marriage!! B110 Sedan Resto B210 Club race car 910 Bluebird hack (Paid NZ$270 for this!) B210 cheap summer cruiser 1 Quote Link to comment

kitchnz Posted March 21, 2014 Author Report Share Posted March 21, 2014 So a long overdue update on the coupe. I see I last updated this thread in July 2013..... Have had a few distractions over the last while, and played around with a couple of 310 sunnys. also packed a sulk for a while on the coupe after lack of progress, so did nothing for 3 or 4 months on it. But back into it the last month or so with rejuvenated enthusiasm! Trying to get my bearings with what I have done on Coupe since July, but here is a basic summary: > New Surge Tank system mounted under car, with submerged pump setup (Bosche 044) & face lift pump new fuel lines permanently hooked up & P-clamped etc > Relocated Battery to boot, new 8ga wiring network etc. also new remote fuel relay setup in boot area with new heavy wiring to both fuel pumps etc (after a small electrical fry up due to under spec wiring!) > Tidied up wiring & new looms, plastic sleeving over etc > Fitted up my Raybrig H4 lights, and fixed my stupid damn corroded light switch assembly > New balanced shortened drive shaft fitted up, diff filled with oil, shifter fitted with new bushes > purchased bolts & fitted up panhard rod properly & centered up rear end > Had Rapid Performance bleed / test braking circuit, fix leaks, and complete exhaust system > Made my own custom spark plug leads & fitted new Coil pack > Finished sound deadening application t o body (Dynamat with combination mass loaded vinyl layer over) > brought a few NOS genuine parts in anticipation of final fitout, like rubber grommets, side markers, front combination lights, armrests, Heater control valve, voltage regulator, > Assembled all steering components & tightened all bolts, new split pins etc > Busy at moment re-upholstering my front (S30/260Z) seats & overhauling the mechanical parts Start up / tuning has been a real hassle, I had a couple of months of no real success, and that brought on a bit of a hyatus of work on the coupe while I sulked! Damn my ITB dreams!! I drove car once up my drive spluttering & misfiring before I stopped work, till I sorted out a few issues! ECU has been away since end of September getting checked out, upgraded and faulty MAP sensor replaced, along with adding a bluetooth tuning module to it, I should finally have back next week! I am real excited & nervous to see what success I have on next startup effort! Few random pics below of what I have achieved 1 Quote Link to comment
Z chopper Posted March 21, 2014 Report Share Posted March 21, 2014 where did you source the ITBs? Quote Link to comment
kitchnz Posted March 21, 2014 Author Report Share Posted March 21, 2014 Hey ITB's are 43mm Silvertop Toyota 4AGE type Look a little different as I media blasted them and also flipped them, to get TPS away from firewalls and also discretely have throttle cable underneath, rather than all the ugly mechanics on the top Running Techno Toy Tuning T3 trumpets Custom made manifold & fuel rail with Bosche injectors (190lb) If I had to do it all again, I would buy a set of EFI hardware ITB's coupled to a redline DHLA40 manifold.....

Z chopper Posted March 21, 2014 Report Share Posted March 21, 2014 am I seeing things right? it looks like the fender lips were widened a bit Quote Link to comment
kitchnz Posted March 21, 2014 Author Report Share Posted March 21, 2014 Yes, very subtle flaring. prob only 10mm wider than factory. To achieve this we took at the secondary swage line out of the lip. Also means I could roll the inner lip up hard against outer. My rear wheels are 14x7" with +2 off set, and they fit perfectly as a result. When we do front guards, we will take the same approach. I wanted car to look 100% original to the untrained eye! so good spotting on your behalf! Quote Link to comment
KiloTango1200 Posted March 22, 2014 Report Share Posted March 22, 2014 Wow, awesome job. Quote Link to comment
kitchnz Posted March 24, 2014 Author Report Share Posted March 24, 2014 Mocked up the refurbished Z seat in position. looks mint. also fitted up my new Nardi style wheel 3 Quote Link to comment
kitchnz Posted March 25, 2014 Author Report Share Posted March 25, 2014 Woo-hoo after 5 months of patiently waiting my Megasquirt ECU is back! Replaced few dodgey bits, includling MAP sensorm and new firmware & ITB base tune been waiting for replacement parts, and new Bluetooth adaptor , so can tune from android phone/tablet (you can see it below ecu, covered in heat shrink) So had to spend an hour or two in garage tonight, Installed Dash up, wired it up, connected New tacho circuit, Fitted up ECU, installed new voltage regulator Also gave engine bay a quick wipe down to take dust off - still happy with how it all looks, just need to sort out a wee surge tank with breather to go on firewall to take crank & rocker breather pipes. just need to fill it with fuel & water, and upload latest firmware to the laptop, and then I am ready for next start-up effort! 2 Quote Link to comment
ggzilla Posted March 25, 2014 Report Share Posted March 25, 2014 Where did it go? Quote Link to comment
kitchnz Posted March 25, 2014 Author Report Share Posted March 25, 2014 Where did the ECU go? I had ECU away with a guy over here in New Zealand, who dabbles round with megasquirts as a sideline to his day job. Was waiting on the blue tooth adaptor and various other components. to be fair I wasnt holding my breath for it, as had a heap of other things to do to the coupe in the background. so gave me suitable time to sort other stuff. 1 Quote Link to comment
