You're right. BMW realised that no matter how hard you try, you can't polish a turd

Allll right i'll give u that one...but one day i ll come back with something so witty it will blow ya minnnd
hehe.. life's nothing without witty banter
TH3R4POR said:Superchargers are relatively easy to fit in the grand scheme of things, I wouldn't attempt it but I am not a mechanic and therefore wouldn't even want to take the head of mine off. Don't get them confused with turbochargers. It isn't "a lot of hassle for 70BHP...", 70BHP is a big power increase!
They are generally pretty much straight bolt ons, and because of that the mapping is easy, you'll be able to use a known map for that specific charger on that engine. Turbos tend to be a lot more work as you have a lot more variety and customisation in the final specification of the engine (going low compression, higher capacity injectors, uprated fuel pump, adjusted boost etc, it all depends what results you were after) which then means the mapping has to be completely custom and as a result Turbos can require a lot of rolling road time to get things just right.
I don't have any experience of supercharging a bimmer engine or that particular brand of charger, but fitting a known brand of SC on a VR block was literally bolt on, update the ECU with a known map, and drive away. You can get the work done in 5-6 hours (the best I heard was 4 hours) and most didn't require any rolling road time at all. I have no doubt this would take longer than 6 hours given the increased complexity of the engine but they aren't a lot of work by any means.
If the kit goes for much under £2000 I'd say someone was getting a good deal. Don't forget to budget for brake upgrades too!
Woots, generally I would guess the thinking would be that if someone wants to add to a super/turbo charger then they would have gone for the larger engine in the first place, they also sell a lot of the 3.0s across the BMW range, You can use forced induction on what you like though, just cause you have a 2.0 doesn't mean it can't be breathed on
Well said!
I would be concerned that the extra power would increase pressuers on bearings etc. They are already at the top of the scale on the 3.0 I beleave.
The engine isn't designed for a supercharger.
Would be interesting to see the results but I would never touch a car that had been modded in this way, just too much stress on the engine components for my liking.
A 70BHP boost at peak is a 30% torque increase on a 3.0i which will be around 40% in the superchargers efficiency zone.
A constant wave of 300-315lbft of torque is definitely not to be sniffed at... Will probaby leave all but the most awake 3.2 drivers well behind...
The M54 3.0i can easily handle 400BHP @ Fly on stock internals. The 320bhp or so from this kit (Including charger losses ofcourse) wont harm it at all

Me too, but then again when you have an opening bid in the hundreds with buy now of £2400 it's a wide band. Also rather specialised product.
I'm not sure if it would it actually bolt onto the 3l prefacelift or need lots of mods?

It states its from an E46, the prefacelift 3.0l lumps are the same engines as the 330 E46s, it'll be less work to bolt it to a pre than a post.
I haven't dipped under the bonnet at all yet really, so have no idea on the amount of clearance etc, but I've seen turbos crammed into some pretty small bays.
I'd not be worried about under bonnet space, more throttle linkages, inlet and manifold configutaion, ECU programming, etc.
He's after £2,200 for it if anyone's interested. I pm'd him, but it's more than I'd pay for an unknown origin and history part.

That's what I meant about messing about, could be an unknown quantity getting it fit, if it was an ESS one maybe more would have done it and the requirements might be simpler, but it seems the sort of thing I'd buy then end up 6 months later with it still in a box.cj10jeeper said:
