How heavy is a 325i? I reckon with some weight reduction, 450 bhp plus maybe a little laughing gas you could play with lambos up to approx 140, after, maybe not.
i think a 325i is around 1200kilo its got a tag on slam pannel with sumthin near 1200 i think
i would say a 450hp e30 would be on par with a lambo without weight reduction or gas? would be a high quote but i think with the correct ratio diff it would be hard for a lambo to pull away
