Tuning a 316i

[aaronsmart]

any good little ways to help the power?
i know its only a small engine but its an immaculate car with an amazing history and i dont want to another engine change
cheers

[Blitz]

Nothing at all.

[aaronsmart]

thought that may be the case

[sihooker]

Nothing at all.

'Not much' would be more accurate...and you wont get a lot of power for the money you'll spend.

[safedave]

strip it out

[aaronsmart]

il take the spare wheel out haha

[sihooker]

il take the spare wheel out haha

Yeah, and we all know what happens as soon as that gets removed...

[Alex]

Fit a 4.45 diff & chip

[Mayze]

318 head and twin 40's would liven it up alot.

But I wouldn't bother if you don't want to change the engine and you want more power sell it and buy a faster car it will be cheaper and easier to insure.

[hazd31]

Stip the bugger out, fit an induction kit (itl sound faster)
but leave the spare wheel, maybe use a bottle top with little tread so its a bit lighter,
alternativly get the push big out the shed and cycle, can only be a little bit quicker!

[Alex]

A 316i head and 318i head are exactly the same

[Mayze]

A 316i head and 318i head are exactly the same

Really they don't have bigger valves in the m40 I know they were different on the m10 as the 318i or 320 head is a known and good modinfication.

[Simon13]

my best tip and cheapest would be fit a 1.8 M40 an extra 20 or so bhp and torque

[SteMarsden]

M4016B and M4018B heads are the same casting number, volumes, valve size, etc. But do have 1.6 or 1.8 cast into them IIRC.

People literally give away M4018B's so would be a very cheap and easy extra 20bhp, plus you have a spare head for when it (inevitably) starts tap tap tapping.....

[Steve-E30]

Whack a i.s. in there , Engines are cheap as well

Only applys to the m10

[Mayze]

Well I never so the differance in power is actualy down to displacement thats a novelty for bmw I thought the majority of 316's and 318s were all either 1.8 or 1.9

[daimlerman]

Suprised that no-one has mentioned installing a K&N panel filter yet.
Even the wife commented that our 316i felt livelier afterwards.
The replacement touring with M50 is much better,though!

[e30ata]

Fit a scorpion back box ,it'll sound as if your going faster even if your not.LOL

[bmw9818]

got the same car m40, you can defo add things to increase the power not by much after it all youl probably get around 140ish, im a student so i cant be asked to convert my engine or anything my ones running nice anyway,

if your handy and can give your car a full service getting back the hp it has lost over the years you should be pretty near that target, heres some of the things that ive bought havnt installed them yet due to the weather! -

1st one looks like for M10 engines
2nd one you're never going to get 10 BHP
3rd You will loose power with that

[aaronsmart]

cheers mate
first person that acualy helped ha

nah i got the right cams i just emailed him, and he sent me m40 ones, and the chip trust me it does work, my freind put it in his vr6 and it did make a difference,

and i dont get why il lose power with an air filter?

I'd like to know how these will give an extra 50 bhp tbf as I can't see it myself.

And improved accl from a back box? I would have thought you'd need to do the entire system to get any kind of noticable gains on a 1.6. Unless this back box is a rocket booster/after burner ala knight rider...

there is no point whatsoever in any of the above parts.
the cam will make a little difference but not a lot unless you improve the gasflow (ported head £££) and map to suit.
the chip? in most cases they will feel a little more responsive but no big power gains on a 1.6, also, what spec engine is the map for? if it;s for standard engine and you've got a cam, it's all but pointless as this new map will be all wrong.
air filter? smaller area than the original one and will only flow more as it filters less. (more crap in the engine) and they clog up too, whereas the paper one can be binned and replaced for a fresh one. also only 5% of the price!!!
backbox? maybe a few BHP at the top end and sound a bit more farty. it will also alert everyone to the fact your engine is missing two cylinders

just save your money and get a bigger engine. the budget above is £400 (plus backbox) and will NEVER make a 50bhp gain!

£400 would get you a bigger engine, or a better car with a bigger engine already in it.

and don't say you can't afford to insure it as that lot will bump up your premiums just as much, if not more.

nah no point in getting another car, seeing as i got it for £350 it is in the best condition bodywork is superb paintwork still got the shine, i dont really intend to tell the insurance comp on a few mods like that anyway,

maybe m535 conversion few years on

until then il stick with the 316 and whatever i can do with it no point in wasting a grand on a car similar to mine just for a few xtra bhp,

[Mayze]

On a different note if you've got £400.00 to spend and you've got a 316 spend it on a suspension kit then you don't need to slow down for the bends. Rather then wasting money trying to get more power out of the 1.6 m40.

In that case why bother paying for insurance in the first place.

[320ise]

really you sound like you want more power than what you have and tuning a 316i is very expensive and not really worth while! best advice i could give is to get a nice m42 in there. if the shells good etc, going from a 1.6 to m30 b35 may well end in tears as the torque is awesome but can lead you into trees etc very easy if your not used to powerfull rwd cars.

[GrindCulture]

Drop an M42 in it. My old iS was cheaper to insure than my M40b18 touring, and now the M42 sits in the touring it's only £22 a year more than with the tappy 8v donk in it. If you're not going to tell your insurance, sure put a 3.5 in it, then crash, loose all your money, your license, your car, and get off the road

[Dave_M3]

4.45 diff (will make a good 316i every bit as fast as a 318iS upto reasonably speeds)

Improve the suspension and brakes and steering with some 318iS running gear and good shocks and maybe e36 rack and have good tyres.

Then fit an M40b18 (with no engine numbers) 15bhp extra if both engines are good and loads more torque low down because of the increased stroke or fit an M42 and do the job properly.

[bmw9818]

yeh i allready got a good suspension kit off a guy on here, brakes yeah im looking into that need to upgrade my rear drums, yeah with the crashing lets just say im a responsible driver for my age, i know my limit and im not relli wanting to dent my beema, and i said il do it a few years down the line which is why the 1.6 with a few tweaks is good enuff at d mo for gettin the hang of it,

[Dave_M3]

If your keeping the 1.6 then for a while...

My advice would be fit the suspension with all new bushings front to back with eccentric bushes and E46 M3/cab topmounts along with a 4.45 diff (these can be found in 316i autos)
205/50 R15s tyres in the form of Toyos T1Rs etc on BBS 15"s

It will be every bit as quick or quicker as a standard 318iS in a straightline to about 80ish and in the twisties.
Z3 gear shift and a E46 rack if can be made fit with the M40 manifold would make the car feel great too.

oh right cheers man, il look into them,

[gareth]

there lies the reason we are all paying too much for car insurance! when YOU are uninsured and crash into anyone else, their policy will have to pay out.
if you do not declare the mods, you ARE NOT INSURED and with a load of stuck on tat, it's hardly going to be hard to spot.
