Hello all

My last BMW was a black E30 318i. I think I paid £850 for it from recollection. Yesterday, after a 25 year gap, I picked up my second BMW; a metallic fern green E36 328i manual cabriolet. Only 60,000 miles on the clock and completely original, I'm planning to get it as close to mint as possible and introduce my 9 year old son to the joys of mechanical engineering at the same time.

I'm interested to know what people think are 'acceptable' mods - i.e. are the ones that allow the engine to reach it's full potential (M50 manifold, CAI, remap) acceptable? Are coil overs and body kits not? I've got my own thoughts, just wanted to see what other think!

Cheers

welcome, new also, not to bmws though.... personally i think when your talking e36 , as close to original as possible... or the very least BMW performance parts i.e. original wheels etc, you've got a good base there, and at that mileage ...jeeeeeez

Thanks for the welcome! I have to say I'm tempted by 'reversible' engine mods - CAI, remap and M50 manifold, and a cat back exhaust. Seems to me none of the above have any bearing on how the car looks, apart from the exhaust tail pipes I guess, but unlock the true potential of the engine. Otherwise I just want to leave it stock. It's got type 32 alloys from new, which are really smart, and the fern green paint and tan interior look great together. The suspension was rebuilt three years ago so I not intending to muck about with that.

No knowledge on this engine but I wouldn't rush out to remap it, cost vs benefit on N/A petrol engines can be a bit stacked against the person paying for the remap. You can shift the torque curve around a bit and find more 'peak' at the hot end of the tachometer but realistically how often are you driving there?

Petrol engines broadly will find optimum combustion with little guidance from the after market, although of course people can, do and will pay for remapping of petrol engines.

A friend who develops 'maps' won't even bother with NA petrols, claiming its all 'smoke and mirrors' and any gains on the rolling road don't tend to reflect in the real world. YMMV depending on what you do to your vehicle.

Welcome back to Bimmer ownership though, sounds like you have a cracker there!

Thanks for that. I've been lurking around as a guest prior to buying the car and there are certainly opposing views on mapping. I think there is pretty much universal agreement on the M50 manifold mod though, whereas the big body throttle conversion seems to have no impact on BHP at all..... All as clear as mud!

I notice you're in the East Midlands. Any recommendations for specialist garages to work on my car? I'm a reasonably competent mechanic but there are some thing I definitely won't tackle.

Cheers

Only engine mods would be air filter and exhaust.
Remap might see gains with those mods done.
