Furai Posted January 8, 2013 Share Posted January 8, 2013 You want the 1.8 diff and housing/axles. Same diff as S2000 and bolts in. Quote Link to comment Share on other sites More sharing options...
mjrstar Posted January 8, 2013 Author Share Posted January 8, 2013 that would be some nasty torsen unit wouldn't it? not a decent plate lsd.. Manifold sorted..Minus some of the unnecessary ugly brackets.. Knocked in the balance shaft bearings in and laid on a coat of paint...

flyingbrick Posted January 8, 2013 Share Posted January 8, 2013 you work at fantastic speed. can't wait to see more Quote Link to comment Share on other sites More sharing options...
Furai Posted January 8, 2013 Share Posted January 8, 2013 The bearing carriers are the weak part on the 1.6 diff, the 1.8 is an inch bigger and much stronger. I t would be a torsen unit but nothing stopping you putting in a clutch type. Quote Link to comment Share on other sites More sharing options...
mjrstar Posted January 8, 2013 Author Share Posted January 8, 2013 Will keep the 1.8 diff in mind, but i'm pretty happy with the ratio selection of the evo diff in relation to proposed tyre diameter and the nissan gear ratios.. Quote Link to comment Share on other sites More sharing options...
Dusty Posted January 9, 2013 Share Posted January 9, 2013 that intake mani looks damn good, very nice welds. Quote Link to comment Share on other sites More sharing options...
kpr Posted January 9, 2013 Share Posted January 9, 2013 this thing is going to be pretty intense, maybe not a scary as the kp though! nice work Quote Link to comment Share on other sites More sharing options...
ProZac Posted January 9, 2013 Share Posted January 9, 2013 Damn, this is some awesome shit, one of my favorite cars, with another of my favorite motors . Keen on details of later model reversed head onto early block? Quote Link to comment Share on other sites More sharing options...
mjrstar Posted January 10, 2013 Author Share Posted January 10, 2013 Keen on details of later model reversed head onto early block? The main issue with the head swap is the extra oil drainbacks which will need to be filled.. but more about that later.. there will probably be some tinkering with the cam drive slot depending on what cam angle sensor is used.. the late model one won't work as it uses a cas and a crank trigger too.. anyway.. I spent some time in the shed today after work.. This is how the turbo is going to sit... it's going to make for an oddball dump pipe but should be able to squeeze it in there somewhere...

ProZac Posted January 10, 2013 Share Posted January 10, 2013 There are a couple of options for retro fitting a crank trigger to this block: Have a look at the later model ones, is probably possible to make some modifications to the oil pump, fit a disc to the crank and bolt up a sensor from a lter motor, or http://www.shop.kigglyracing.com/product.sc?productId=3 combined with the factory cam sensor on that head should give you the correct triggering pattern for any of the wasted spark mitsy ecus. Doesnt look like there is much clearance to the bulkhead though, for a head mounted CAS? Love your work Quote Link to comment Share on other sites More sharing options...
flyingbrick Posted January 10, 2013 Share Posted January 10, 2013 keen to see how you will fit the other two runners in haha Quote Link to comment Share on other sites More sharing options...
mjrstar Posted January 10, 2013 Author Share Posted January 10, 2013 keen to see how you will fit the other two runners in haha Me too.. should be able to sort something out by the end of the weekend.. i really needed that number 4 runner to tuck forward as much as i could to give maximum dump pipe room.. Factory CAS is installed at the moment, not much chance of removing it with the engine in though.. i guess i could recess the firewall a bit but have been trying to avoind that at this stage.

ProZac Posted January 10, 2013 Share Posted January 10, 2013 You'e got me thinking about these heads now.. they're always pretty cheap, and if it's not too much hassle to fit one to an early block.... Swapping exhaust and intake sides would sort out a bunch of clearance issues I'm going to run into when going to rack and pinion... Plus it would just be so cool! How have i not read this thread before?! McLovin' It. 1 Quote Link to comment Share on other sites More sharing options...
mjrstar Posted January 10, 2013 Author Share Posted January 10, 2013 the other issue with the head swap will be the cooling system, as the thermosat would normally mount off the back of the head, current plan is to mod the spare mx5 thermostat housing and remote mount it.. i have learnt that turbo on the drivers side is a headache - detials in the starlet thread. and the late model head looks cooler too, i have not seen this particular conversion done before?

ProZac Posted January 10, 2013 Share Posted January 10, 2013 There is a Starion over in the UK running the combo, its a widebody racecar, will try and dig up some details. Yeah, you strike the saem cooling system problem using the older heads too. Best option, IMO, is to modify the coolant passages in the head to reverse the direction of flow, and then knock out the frost plug in the front of the head and weld a thermostat fitting of some description on there. Not sure what to do with the later model heads though, do they have a convenient frost plug on the front below the cam gears at all? Quote Link to comment Share on other sites More sharing options...
mikuni Posted January 10, 2013 Share Posted January 10, 2013 When I built my chevette we capped the back of the head where the old thermo sat and rerouted the water through the EGR system so it spat out of a conveniant pipe at the back of the intake manifold. From there I just had an inline filler cap on the hose to a radiator. It's probably the only setup in the world like that, but I think it's good to think outside the box with this sort of stuff.

flyingbrick Posted January 10, 2013 Share Posted January 10, 2013 you had an Evo motor in your chevette?.... because that would be cool! haha Quote Link to comment Share on other sites More sharing options...
mikuni Posted January 11, 2013 Share Posted January 11, 2013 Nah but just saying what I did with the twincam due to similar issues, because running water through an EGR port probably wouldn't be the first idea that pops into peoples heads as a potential solution to the problem.

fuel Posted January 11, 2013 Share Posted January 11, 2013 Evos don't have EGR (well, at least within the cylinder head anyway). They do have a frost plug on the timing belt side of the cylinder head which you can fit the thermostat housing to and modify the coolant flow from the rear of the cylinder head to the front as opposed to the opposite direction as it would be from factory.

ProZac Posted January 11, 2013 Share Posted January 11, 2013 Havent yet seen anyone do that with a later head... looks to be dooable tho, can see a frost plug in a couple of pictures. Quote Link to comment Share on other sites More sharing options...
