anything above a digi 2 hehe just depends on ya budget dude. but in all seriousness if its running fine why change it.. no need to reinvent the wheel if it works ok. your not in a drag car chasing the tenths of a second.. off memory digi2 has a single wire off the coil for an ignition input. now if you plan to go down the upgrade track any upgrade means you need a series 4/5 cas for the ignition. as for ecu depend on ya budget (either second...

also to aid stratification in petrol applications { h2 wont need it but requires a cold area fuel intake separated from the incoming charge of the next flank } ( 4- 96 % explosive limits !! --this is why the h2 engine has the top injector ) but,, maybe search ROSCO ( rotating stratified combustion ) ,, as this is when mazda first tried the stratified charge technique with semi direct injection on top of the engine then came the SCP engine (...

Did you have a look at the tread that popped up here the other week? Mazda's redesign of the 13b, part of it wass direct injection - however they were injecting into the chamber near the top - in the inlet phase. Im suspecting it had something to do with lubing the apex seals - if you inject directly into the combustion phase, you wouldn't get any lubrication.

yeh mate spectrum rubber are good !used them a few times

Lubrication nill you say,does not figure,omp is still injecting oil and thus still lubes the apexes on rotors,now add small screw compressor to the equastion...add some injectors(placed accordingly)and is there a reason why this will not work?my bases seem to be covered...there is still the suck squeeze bang and the blow happenning,critical part boost required and the software for injection/spark timing. does it have to be petrol,why not lpg...

Give it a couple more days, turn it over at least daily, the more often the better. Centrifugal force could make them come out, if it will run at all. If its been sitting for a while and they are seized then it might be rebuild time.

yeh, ive heard of people doing that, but i have no idea where to get the pulleys from...? anyone know of anyone that has or knows where to get a gilmer with a/c? Im in adelaide. cheers.

just use one of these

So you have a 12a with a high mount AC compressor, and want to change to 2nd gen compressor? Don't know if the comp will bolt up to the bracket sorry, but can confirm that the two pipes comming through the firewall fitted straight up to compressor flexible pipe and condensor pipe
