Looking to gain more power from my 318. Apart from changing the exhaust, air filter and remapping whats a good way of upping the horses? I've heard changing the manifold for a 328 is a good mod but suggestions would be appreciated.

Didn't think it could be done but sure i read in Performance BMW that it could. Thats why i was asking? Not had a BM this low in the power before. Was thinking of a engine swap, what would be the best to go for 328 or a 3.2 M3?

Gav, which works out cheaper, SC, Turbo or itb's?

Robbie Im new to the Bimmer thing to dude so im asking the same questions lol.

im interested in the inlet swap.......

Would be cheaper with a transplant mate.

If your willing to fork out and put time in, best you could do would fit a 3.2 M3 evo.

But by the time you have brought lump, gearbox, diff, brakes etc, you prob could have brought a Decent Evo.

Thats what i was thinking. To be fair i bought the car cheap as a little run about for my ex. It was too good to scrap so i thought i would do it up, give me something to do, but i need more ponies. I'm cutting my teeth on this and trying to do most of the work myself, but i think it maybe cheaper changing it for an M3. Like i said this is a project for me so i'll see where i take it in the next couple of months but any advise would be great?

I can understand dude.

Forced induction is probably your best bet, maybe a supercharger and creating your own kit would be a nice project.

Thinking of creating my own S/C kit and adding a S/C to my 330ci next year.

Thats on my shopping list for my 650, which should make it untouchable, but whats this kit your thinking of making for your 330? I ain't no mechanic so you might have to talk in laymens terms. Lol. Wouldn't know where to even start about making my own kit. As for putting it on my 318, think i would rather upgrade the car to a 328 or M3 Evo and doing it to that. Think it might be wasted on a 1.8

Hey Rob,

As snypa said, your motor is a 4 Cylinder so you can't fit a manifold from a 6 Cylinder onto it.

As for an engine conversion, there really is no point. The M3 engine works well in the M3 chassis where as it would not in your 318i chassis. This is because the absence of the uprated suspension, Diff etc. etc. Unless your going to do something really fun like put an S model engine into a car that it was never factory built with, there is no real point.

I say drag as much power out of your 318 engine as you can! :D

      Tyres..what's the best alternative to run flats

      Morning Jon The main reason I moved away from run flats with the X5 E70 was tyre choice, with my E53 X5 I had plenty of practice. I learned that the recommended Star marked tyres were (a) not necessarily easy to get (often on back order) (b) They were also very premium priced (as you know) I started using Bridgestone and Hankook and found that they were as well matched in a staggered set as the Star marked tyres so no transmission damage. I brought the E70 to cut the miles going onto the other X5 and quickly moved it onto Hankook non run flats a set of 4 285x40x20 Front and 315x35x20 rear was just under £800. In my breakdown kit I have as said a small compressor a can of tyre weld (or similar) and a tyre plug set. I have used it a couple of times a friend of my wife has a Volvo V60 on run flats she ran over a screw one of the plugs fixed it and stayed fixed until she needed tyres. My son inlaw suffered pot hole damage to his 330e when visiting us, a can of Tyre weld got him from Sussex back to the West Midlands where they live. When he went to the tyre shop they said "shouldn't use that stuff mate we cant repair tyres that have it in" well with 2 splits in the inner side wall it was a new tyre anyway but at least he could drive 190 miles and not be stuck overnight waiting for somewhere to open. If there is a puddle I slow right down or go around if I can because in sunny Sussex it will be a Pot Hole I would go with a repair/limp kit like mine and fingers crossed the roads on the continent are in better nick than ours As an aside our son inlaw started a claim against the county council it took ages to get a resolution they wanted to know how many miles the tyre had covered ? then how old was it then said as it was a used item they couldn't offer full value !!!! An invitation to appear on Rogue Traders finally got through Dave

      Clicking noise when disengaging the clutch,

      Clicking noise when disengaging clutch either when pulling off or changing gear, happens more in lower gears but can still happen in higher gears. if sat with engine running, in gear and handbrake on, and slowly release the clutch until it’s hitting point I will make the clicking noise aswell any ideas as to if this is serious or just a common bmw noise?

      Tyres..what's the best alternative to run flats

      Hi Dave, thanks for your fantastic reply. I'm on a staggered set and I recall the wheel shop retailer was concerned about the M40d brake calipers and the 19" space saver not fitting 21" wheel. Hmmm, been researching more, and people either love or hate RFTs, think I'm stuck with them until pcp runs out in Dec 2025, but I'm now nervous about long journeys abroad cos each time I have a sidewall blow out, there's no way to run the car for any distance without wrecking the rims...

      Tyres..what's the best alternative to run flats

      Hi Jon Welcome to the Forum First is your car fitted with a Square wheel set (same size rims front and rear) or a Staggered wheel set (Wider rear wheels than the front) I suspect your car will have a staggered set probably 8j Front and 9.5j rear, so fitting a space saver wheel/tyre will mean there will be a different rolling radius on one wheel which can cause damage to the Transfer case and or diffs quite quickly if driven on for any distance (probably why your Dealer was vague) Even if your car has a square set up if the rolling radius of one tyre is different damage can occur. It isn't just BMW who suffer from this many 4x4 cars have the same issue. First you would need to check the Off Set to make sure the 19" wheel clears your Brake callipers and fits in the boot along with a Jack and wheel brace. Then if you are sure it is only a real emergency measure and not a solution that will allow a distance to be covered and aware of the risks why not. I have 2 x X5;s both run 20" staggered wheels and early in their lives I changed run flats for standard tyres (as generally they are easier to source and wider choice, care still needs to be taken that front and rear Rolling Radius are closely matched) and I keep a small compressor and Tyre goo in the car in case (BMW actually supply these as well). I have used it twice and happy to say not on my car but to help out others. Hope this helps not confuses Dave
