Food for thought https://youtu.be/0s4gbjawWms

Dave forgot the diff --you chaps have the alfa diff --just slightly wider and 108pcd - not really a prob.Has rear discs.HEY you can see i'm getting tired --chopping my sentences

Dave it's difficult to advise -- This is what i had done:A14 motor, A15 crank, 79mm pistons[opel or in your case vauxhall]A14 head port gas and flow,double springs[not datsun]bigger valves,laser cut intake face,had intake made from that [itb]got t/bodies from UK zx6 which are 38mm and zx10 injectors,dizzy is changed now a hall-type,Vw radiator,blocked off old fuelpump and used VW combi pump with fuel regulator,5 speed ute gearbox,alfa junior lsd,drive-shaft is the same in front just gotta change the back and length [allow for weight in car]almost forgot cam was done,OH another thing Gotech Mini X ECU --dyno end result with probs i had almost 100kw -- base map.I would love a TURBO set-up but when i pay i want results-- not s/bodies crap cos he's in a hurry to take your money.BUT you are in the centre of m/sport R & D so you can pick and choose.SOOooo lets look at choice of goods: HEAD- GX or A14; V/springs good tuner can help,DIZZY hall type or another datsun/nissan elec dizzy [i think VW also works with a few changes]PISTONS - your choice you may want 78mm. FLYWHEEL --lightened or you get 6kg and 9kg i think it is on datsun sites but most are going to tell you not to go too light cos it's bugger to drive-- BALANCE e/thing.CARBS/throttle bodies -- could use hayabusa.ECU -- i see you chaps in the UK have a wide range even the Spitronics from RSA as per ad in Japanese performance/Banzai. Make sure you make good HP [turbo,turbo turbo]and let them do a write-up about the 1200 cos i've had enough GTR's 200sx,rotary etc.TIME FOR DATSUN 1200 now

Depends how far you want to go? A15 crank --peter zekert sells cranks, 78 or 79mm bore,if you like gx head or stick to A14 head,bigger valves,double spring,[shikes cant even remember what springs i have]port & flow [lot of sizes you can get by forum chaps]power is made in the head.--pistons well depends if you want to go NA or turbo,electronic distributor,throttle bodies or carbs [opinions differ],flywheel.DDgonzal is actually the chap to speak to about mods.--valve sizes,spring rates etc.he's prob sleeping --will chip in with all the answers -- time diff

Seen that coupe run a few times but now i had more time to look at it carefully [the last run]DAMN that bonnet opens up on the side --It's like the datto saying ''give me some air gotta get air''

hi Dave there's quite few sr20's and also A14 engines on this site.The SR chaps use the SR20ve --well those that can get hold of it or afford it [on this site -- racetech].The A14 is used with A15 crank -- can push 100kw easily or you can go overboard like the Porto ricans on youtube. google'' Cocoliso jeep with A15 turbo'' For the Sr gotta stroke the gearbox tunnel a little and A14/A15 the engine mounting points differ on crossmember.So whatever floats your boat. https://youtu.be/SAUsM8NOy6k

nick check this out-- test coilovers vs Air https://youtu.be/7dQgT5g84ag three car test no2:THIS is quite a laugh datsun 1200 https://youtu.be/XZ5qsnH3MZA and the same datto https://youtu.be/yB5d8fjF99k

Just had a quick look -- not sure if link is good - https://www.airliftperformance.com/vehicle/subaru-sti Ok if that dont work just google Subaru with air suspension. It's one that say's [2008 to 2014] read that and check what is needed --all in the pic. It's 550hp subie. think it's the same as the one in the mag

Nick i have been thinking about the same thing.I have no experience with cars& air suspension but i have been thinking about installing a air system myself. I do have exp with bus air bellows and let me tell you a co driver one day called me to the front of the bus to show me that the thing can run flat cat through a S-bend [lol]All you hear is pssss, pssss when those bellows are working.We used to replace our own bellows cos they would come out [not often though] PROBLEMS : air bellow that pops [old and perished] air leaks in the system,load sensing valve not operating correctly, compressor problems.I have just got [july month] Japanese Performance mag and there is a chap with new shape subaru [hatch back] with air suspension and he reckons it's cool. [maybe you can google it]In short -- can drop down,pre-set adj on start up,height adj etc all controlled in car. Biggest prob is probably installing in a datsun [cant be so bad]The Subaru has a strutbrace and Eibach camber plates as well.I think you should read about the whole setup and take it from there.Personally i like the idea of air suspension -- been on real bad gravel roads i'd say similar to Aussie outback with the bus and they take a beating.In RSA there's a Co called gremeltech that does air suspension but there should be a few in Oz

yeah must be --date says July 12 -- geez the things i did when i was that age.Saint peter prob said '' listen here dude this is the third time you've got away with it,you are a problem child i'm watching you''
