Never said it was the best engine (hence mentioning r36's etc). But if you wanna rebuild an old 16v made out of a shopping list of 2nd hand parts, and then manage it, sure, but I'd rather grab a bam lump, forge it, qpeng it, and drive it.its like saying well I've got an old 'a' series engine, if I do everything to it it'll be better than a 20v?!sure if you want to. 16vt was cool 15years ago, just look at caistor bmxs fooked engine!! 20 valve isn't THE best engine available, but for £'s, and ease of getting a good one, plus spares, plus upgrades it kicks the fook out of a 16vt. Didn't realise the heads were worse tho?! I guess people have tested and proved that yeah..?
