Assume you're talking about the 1.8 OHC Family 2 engine as used in the Manta 1.8 and front wheel drive Vauxhalls?

Don't know what the weight is; they're regarded as being a heavy-ish engine by modern standards, but the construction is lighter than the 1.2 and they're alloy head, so I'd be surprised if they're that much heavier - say around 50 lb / 25 kg at most.

By 1.6 and 2.0 Kadett springs I assume you're talking about RWD Kadetts (B and C models)? No confusion with FWD (Astra type)? The RWD 1.6 and 2.0 used the Opel CIH engine like the Manta GT/E, and they're big old iron lumps. This means the springs for a given use are likely to be over beefy for a 1.8.

You probably wouldn't be far out with something that'd suit a 2.0 XE conversion, as they're only slightly heavier, but I've not done or driven an XE so that's only a guess.

Having said this, what springs to go for probably depends on what you what to do with the car and how stiff you want it to be - personal preference really. I've an idea what I'd go for but that may not suit you; best thing to do is probably ring Tim at TJM, maybe Ian Jemison and the like and find out what they'd advise and what they've got available.

Sorry i should have been more specific, i'm wanting to fit the 1.8s which originates from the manta as you've said.
I've bought some bilstein shocks, i've seen that spax & avo do springs for 1.2, 1.6, & 2.0 kadett all lowering springs, due to the weight issue i'm not sure what poundadge would be ok for the 1.8.

didnt we establish you could just use manta springs? are you using billies from a manta GTE or have you paid through the nose?
when all else fails, rivets, cable ties and bodge tape will see you through
