[jam-77-nova]

just been looking at codes for 20seh as had one in nova years ago n was quick n have had 3 xe's since n dont seem what they shud be as only slightly faster,so have always had softspot for them, anyway i knew the seh was high compression version of 2l 8v mine came out a mk2 cav sri 130 and when looked S is the compression E to do with injection and H it says high output/superchargeing,, what does the last one mean/ refer to?????

as in the letter H? exactly as you say, 'high output' as the 20SEH is 130bhp compared to it's lower powered sibling, the C20NE which was only 115bhp
