Bhp

[tertius]

////Ms.....every BMW is a M now a days with the amount of M badges i see like the E89 2L
I would like mine to be a 3L then add a ESS supercharger, along with a sports exhaust, or turbo charged, grumpit etc.....something unique or stick a V8 or V10 in her but all of that is 5 figures. most of us want more BHP but it is VERY hard do do much with the 2L im affraid, so either be happy with her as OEM or do the mods ive done ( which have helped even the sprint booster chip makes trottel response MUCH better ) or get a 3L then increase BHP how you want which there is many options or buy a ///M

Hear what your saying Jonny ///Ms are so common (that should put a cat amongst the pigeons)

////M.....nothing unique

Quite right, not unique at all, just the best ...

Much much more Jonny with a rebuilt and upgraded engine the m54b30 has pushed out 800bhp from a turbo set up..........

3 litre will be best compromise in terms of power and running costs and initial spend.

Or you use a super chip that'll give you 90bhp gain guaranteed. They're free if you send your bank account details to Uncle Benson in Uganda.... Next year shipping is also free.

Grab a 3.0 and you won't be disappointed.

When you upgrading JE?

The only problem being you'd need to be very handy with a set of spanners to keep it running - I'm sure ///MM had the requisite skills, JE... less so.

Not sure about that Perry you might be over egging my talent.

Anyway a car that blows up on the way to the shops is not quick. Nor is a car that only has a lot of horses at peak revs. But I think a small turbo quick to spool up so responsive should be able to put you close to 450 Bhp??? Same with a S/C like a ESS running more than 7psi they are at 320bhp running at seven.

I went from a 2.0 to a 3.0
So much more power and the delivery was alot smoother also

Whaaat? How can they substantiate this? (honest question, I'm not a tuning specialist)

Wow what a bargain!!!

Lol f**k this, 2L woes....add this like me so far:
K&N air filter
Sports exhaust
Remap
Gave me 12 bhp mid range 20 bhp top range although the " big boys" doubt this but have thr graph to proof this.
There a forced induction option but will cost 10k, i kept mine as had since new with you i asume urs isnt so if you need more power sell and get a 3l

We'r all still waiting to see this "graph"

If you want some extra power look into getting some cylinder head work done with the valves enlarged and polished, and possibly some different Cams? From experience it'll be at least £400-£900, plus air filter + exhaust. And the FINALLY a proper ECU replacement (not a generic 1 off ebay) but 1 that uses a rolling Road and is bespoke to your car.
Then your looking at 175bhp to 185bhp but with LOADS of extra power lower down and free'er reving.

I know these guys are awesome! http://www.technosport.co.uk

But that said you don't need to use a specific BMW specialist, ideally find the best Engineering company, as the experience required isn't manufacture based. I previously owned a Astra which I had 2lt 16v Turbo engine swap by http://www.courtenaysport.co.uk all though there famous for there Vauxhall race engineering, I ended up taking my MR2 turbo there too for a porting and polishing after the head gasket went.

The basic principal is enlarging and smoothing the inlet and exhaust paths and valves. You can spend a fortune on induction and exhaust modifications (basically to help the engine breath in and out), but the engine is still restricting airflow / how much a air filter and exhaust can work. If you can improve the engines air flow in and out, you get more power.

Changing the cams at the same time as head work (changing the length of time the valves open and shut), can bring awesome results, and it's not overly expensive on a 4 cylinder engine.

That said....
Iv had this done on a few cars (most 2.0lt and under) with massive gains and improvements, but I personally I still wouldn't on my 2.0lt engine because The cost vs gains = not much on the BMW engine, it's a pretty pony engine compared with older engines from other manufactures (that said its more reliable then others). There's a lot of Labour cost in Removing a cylinder head, so if your car is due a head gasket change, this would be the ideal / most cost effective time to do this mod.

I recon only up to 175-185bhp Max on a 2.0lt Z4
Guessing its costly too.

Example a NON turbo MR2 with 175bhp as standard,
after Stage 3 race head (£950) including 2 race cams, induction kit, up rated injectors and fuel pump, unrated exhaust with no CAT, then a bespoke Chip = 223bhp
+ the bhp gains start lower down and the engine revved so much freer.

Also needed a unrated clutch and oil pump later on. Total cost came to Nearly £4k tho :|

That would piss all over Honda civics, standard Turbo MR2's & Subaru WRX's etc
But....
The amount I forked out for it was pointless really I found. A couple of my friend had a standard MR2 turbo and a SCOOBY WRX, with in 2 months of me finishing my awesome MR2 racer, they both went and got there chipped together £400 each for 4 hours work and BOOM both over 250bhp :|
Bags more Torque then I could ever get from a NA 4 cylinder.

The moral to this story is, don't bother modifying just swap to a bigger engine or buy a already turbo'ed car.

Thanks for info, what do reacon it would cost to port and change heads and the gains from that?

I cant see the point in all this, you will pay a ton of money to get close to the 3.0 output then even if you get close to 231 bhp you still have a 4 pot lump, i think that any 3.0 owner will agree when i say get what you can for the 2.0 and purchase a 3.0, the thing about the 6-pot is it's not just the bhp that improves the drive, the six is just so creamy smooth and it just sing's to you.

 

[un1eash]

Trying to squeeze more power out of an engine like the 2.0 is just wasting money. Simple breathing mods like an induction and exhaust will make it sound better with minimal gains.
If you really want to go quicker from A to B then a driving training course would be money well spent.

 

[Yorkie Z]

I have the 2l engine which is fun but I want more power. Is there anything /mod I can do to get an extra 30-50 Bhp?

Thanks

I was in exactly the same boat with my 2.0i, ended up just buying a 2.5si - with selling my old one and buying the new it only cost me £300!

Best thing you'll ever do!!

Buy a 3.0 if you gonna do that, crazy only going to a 2.5 IMO
