just quickly about the plugs.

being an NGK r really doesnt say much about the plug. Its detailed specifications are buried, encoded in the part number, for example bcr6es and bcr7es. the numbers relate to the heat range of the plug

a 0.7mm gap shouldnt cause any problems although for mild tuning is a bit narrow. From memory until you're running aproximately a bar then a 0.8/9 mm gap did people fine with the heat range 7 plugs.

they are bcr8es plugs. ive set them to .9mm...

the car is running 1 bar of boost.

i will put them in today and fingers-crossed it will work.

I'd put them back to .7 tbh otherwise you might get the spark blown out at that boost.
A compression test is what I'd be doing first on this car.

ye, 0.7 on 8s is right for that boost

well just put it back together...

started it after 20 seconds of cranking...

it began missing, but then kicked into life with all four going... after about 20 seconds of being on all four, it started to resist and drop onto three, then it wasnt long before it stalled.

whenever i put my foot on the accelerator it began to die.

why would it be so hard for it to kick into life and then die after 20 odd seconds of being fine?

Do a compression test and post the results.

thanks

do i need a 10mm adaptor for the S12? the kits all seem to be 14 and 18mm.

Yup i fitted these to this car last summer, Have faith David!.

All correctly torqued up too..

Do a compression test. But get all the plugs out first.
Try using a decent 16mm deep sparkplug socket,UJ and extention bar. It will get them all out

Aslso check no split oil has gone in the injector contacts

yep john you did a good job considering the state the car was in before.

i couldnt be bothered to get a compression test. but it wasnt that anyway...

there was water and oil inside the dizzy! i swear i checked! it must be a crappy cap or something, so going to replace it. the oil came in from me spilling oil on the rocker cover i think...

after driving another car around for a while and driving my silvia, ive noticed my chest has got hairier.

cheers for the help.
