BHP help?

[Talksthetorque]

If you want to go faster, get your bike licence (if you don't have one already) , and get a bike and take it on track days. Or buy a fast small hot hatch/E36 328i and do the same.
Keep this for the road.
A nice looking car that is not fast is still a nice looking car.
It just means people have a bit longer to look at it as you drive past.

Anyway thanks for most of you with the poor help on the extra BHP with this thread, i thought we was here to help one another. :thumbsdown: :thumbsdown: :thumbsdown: :thumbsdown:

Bit harsh Jonny I don't think you have had any advice that wasn't genuine, personally I know what it's like to get carried away spending on a motor, whether it's upgrades or repairs when the truth is I should have left it alone or moved on, the advantage you have is someone giving good advice.

If you are going down the tuning route I doubt there is any alternative to SC for the 4 pot 2.0. There is a kit by ARMA but I'm not sure of the precise engine. It sounds bloody nice but I can't imagine it being long before something gives out, still it better to go out with a supercharged bang than a 2.0 whimper :wink:

Talks every time i see a pic of your wheels i think they look great on the car, then i see mine and think no they look good too :? :? You are messing with my mind :headbang: :headbang:

OK,et's explore this for a moment:

A) what power does your car produce at the moment (officially or measured)
B) what is your (reasonable) target?

I can imagine, in 10-15 years time, people may very well be chopping and swapping engines between models without much thought as they hunt for the best shell/engine combo. The problem for you Jonny is that right now, this isn't a well trodden path so anything like this you undertake will mean you, your car and your wallet are guinea pigs and that inevitably means problem solving, lots of time and inevitably lots of money. Another thing that I haven't seen mentioned is how easily interchangeable the 4 and 6 cylinder engines are. Do they use the same mounting points on the chassis or are there additional brackets on one or the other?

There's also the issue of the electrics. Will the clocks just plug and play or do you need a different set? All of this might very well be irrelevant and you may find that it's relatively straightforward. You may also find you wish you never started.

Whatever you decide make sure you go in with your eyes open, if I were you I'd be doing as much research and part number trawling as possible to try and understand as much as as you can. If you do go for it then as mentioned above, getting an entire donor car would be a good idea as then you'll have everything you need and can sell of unwanted parts to get a bit of money back.

I feel most if you dont really love your Zeds as much as me, thats the difference, i love my car slow or fast.

How do you know if you'd still love it being fast :wink: oke: oke: oke: :fuelfire:

Chasing figures on a dyno is stupidly expensive and pointless if I'm honest.

Chasing a car that drives that will continuously put a smile on your face, that's a different ball game entirely.

I love my Z, I love driving it, polishing it and generally taking damn good care of it, but at the end of the day its a Z4, not a Ferrari. There's more worth while things in life for your money than pouring it into mods for a car for which you get no return on when it comes to sell.

 

[andysat]

I dont think anyone on here is trying to bring you down,its just that on your opening thread statement you said you wanted more power,and members are only giving you their different opinions,wether you agree or not it is an open forum with obvious differing opinions,and we all looove our zeds on here

 

[aquazi]

This thread its almost comical.

I think there has been perfectly sound advice, from all aspects.. Engine swap, SC or just sell for a faster one. But you have selective reading and want to claim nobody on this forum loves their car as much as you :?

Give it to steve and pay him to put a v10 in their after he has finished with his... Conversation over!!

From experience in other threads (big brake kit lol's) Jonny doesn't take people's opinions/experience very well......

 

[Adamski]

That's why I asked what response Jonny was looking for. It seems a forum of advice isn't the desired answer :idunno:

[Luke the spark]

So Jonny with all options said, what are you going to do?

I'm sure I've said this in another thread but personally I would spend money on yourself track days, tutiton
Learning to properly drive
And by doing this I think this will be the most rewarding.

 

[GregZ4]

Johnny, just my advice :wink: Take what mods you can off yours and sell it, you have got a fantastic car that somebody will snap up, then the money you were going to spend, put that towards a 3.0 then put what mods you have back on and start again, thats what it is all about You will have the power base that you can then build upon and produce what i am sure from your threads will be one of the top cars on the forum
Oh and you need to get a coupe for it to be the top car :rofl: :rofl: oke: :fuelfire: :tumbleweed: :evil: :rofl: just about covers that

+10000. Great advice Rusky. Quite the best post on the thread! :driving:

I agree with you as it happens, but the OP started by saying he wanted "more power" so I was starting off by trying to understand the task at hand. Bit hard to answer without knowing at least roughly.

 

[Adamski]

According to wiki (which is never wrong :? ) the N46 had power outputs ranging from 129bhp to 150bhp.

http://en.wikipedia.org/wiki/BMW_N46

I always thought 150bhp was the zed 4 pot output.

Getting an extra 50% power from a naturally aspirated engine, which would take the 2.0i to approx 225bhp, is an enormous amount of effort, and would still be shy of 3.0i power. Also, with forced induction, internal engine parts will fail when you get to 50% increase in power, as they simply aren't designed to take the power increase. Upgrading internals becomes really expensive, especially when the engine isn't typically used by tuners.

My friends up north are all Jap car crazy. Bolting big turbos on and cranking the boost is the norm. Picture below of the Silvia, it's a 1.8 300bhp machine. However, it's on its 5th engine, and goodness knows how many re-builds



Not trying to rain on the parade. Just saying that the Nissan Silvia has huge tuning potential due to the quantity of parts produced for it. And it still blows up.

The 2.0i N46 platform has few tuning parts available so isn't a good tuning platform. Hence the best way to get additional power is to upgrade the car or engine to a 3.0i or 3.2 M.

Alternatively, do a Stevie and get a 5.0 V10 M engine

 

[PlumbNB1]

If everything is to be considered is there a nitrous oxide boost option??? Just saying :tumbleweed:

 

[PlumbNB1]

Maybe not then!

"The increased pressure and temperature can cause problems such as melting the piston or valves. It may also crack or warp the piston or head and cause preignition due to uneven heating".

 

[srhutch]

I always thought 150bhp was the zed 4 pot output.

They were all 150bhp, the other outputs were used elsewhere.

 

[paulgs1000]

Hmm

Not sure about all this talk of more power. . .what about making full use of what is available?

One of the reasons that I love my Zed is that the engine can be revved to the limit in second and third to 80 mph and that's licence friendly and fabulous fun.

My TVR Chimaera was one of the fastest cars I have driven but could only be used occasionally to it's limit - whereas I find nearly every drive I can exploit the full potential of my 4 pot - brings a big smile to my face everyday and my wife and I come from a background of fast superbikes.

The logic of creating a car (or even owning one) with more power on todays congested pot holed and increasingly poorly driven roads does raise questions of why? (I live in the North East where access to wonderful roads is far better then 'down south') How often do we get to enjoy the full potential of 200+bhp cars safely on the roads today? I spend a lot of my time tapping into the max 150bhp of the four pot and enjoy the challenge of getting the best out of the car. Not certain that would be the case if I had 200+ bhp. So lets lay off the 2.0 engine (and their drivers) and recognise the challenge of getting the best out of any of the Zeds. They can all be fun - especially in the twisties!

So why not have the best 2.0 litre 4 pot on the forum and drive it to it's full potential?

It's quite a brilliant 4 cylinder engine - you might be better off looking at gearing which in my opinion IS suspect on the 2 litre and could be improved to enhance real world performance - it's no 6 gear tourer - is there a close ratio box you could use?

:driving: PS I love my Zed too as do most of the members of this forum - that's why we're on here. BUT there are many other things I love too - far beyond a mere car - balance needed . . .
