NB Cylinder Head

Postby DarrylA » Mon Oct 07, 2013 5:32 pm

Hi Guys
Can anyone tell me how to find out what cylinder head is on my 1998 1.8 NB.
I believe there are lots of variations. I was hoping I can find out by engine number.
I want to buy a spare head with cams, so we can do a bit of playing around.
Thanks guys !!!!!!

Forced induction or natural aspirated horsepower? MX5 Plus are doing a FI version of my head you pick the cams, valve springs etc however you will need to use a block with 85mm pistons. Compression i believe will be 9:1 where as mine is 11:1 as it is non FI.
