weber 45s on a 318is

[AlpineAde]

some nice mods there

4.10 lsd i bet that took some finding

is it worth removing the heater plate????

mods ive done:

13 button obc (needs fitting)
map light mirror (needs fitting)
dye carpets dark grey
fit unworn tech 1 wheel
new bmw gear nob
new gear gator
get my 15" bbs refurbed with new center caps
de chromed leccy ariel
fit tweeter pods along with comps amp etc etc
fit tech 1 spoiler
clear side and front indicators
service

the list goes on

still got loads more to do

the plan is to spec it up as much as possible

To add to all the cosmetic stuff you've done/plan to do your car, sort the suspension and brakes first. Never mod for power first. That's going arse end first. And if you want cheap speed work on the power to weight ratio of the car. Loading it up with electric gizmos and body kit stuff adds a lot of weight and sucks performance out of the car. Taking a little weight out of the car is essentially free power. And you can't get cheaper than free.

Throttle bodies are a sensational thing and a joy forever but on a stock engine there really isn't much point. If you are after throttle response (and you will get bags of it form ITBs) have a think about a BBTB and porting the inlet manifold. Much, much cheaper and the throttle response is excellent. You'll get a few horsies, too. Match that with a chip and a free flowing exhaust and you'll be on your way.

anyone any idea on the price for new suspension bushes etc from bmw then

i recon the brakes may need doing after it being stood for 5-6 month, i would get some bmw items and renew the fluid, should give it a better feel

[GrindCulture]

Cotswold are only a few presses of the mouse away for a quote.

[Alex]

dont really want to bother them again

i keep asking for quotes and never end up getting anything

[Jon_Bmw]

If you find the part numbers it doesn't take them long to price it up.

[Alex]

what bushes etc would i need to overhaul everything and make it tight, anti roll bar, rear sub frame bushes,....????

would possibly lower it 35mm at the same time

[Dave_M3]

Rear subframe bushes
trailing arm bushes (even though they don't usually wear, you might as well do them when the rear beam is off)
Control arm bushes (E36 M3 eccentric ones)
arb bushes
arb drop links

Maybe H&R/Eibach or KW springs depending on what you want and if you could stretch to new shocks.


Should handle pretty nice with all those bits

[Alex]

bring on the summer, my pay goes up by nearly 50% too when im 18 too more spare cash for the e30

i dont want a harsh ride mind you

[AlpineAde]

Then just be sure to steer clear of coilovers and don't go mad with poly bushes and you'll be fine.

would only use genuine bmw bushes and dont fancy coilovers

[AlpineAde]

Like me! I find OEM bushes and a good spring/damper combo is perfectly acceptable on a car that sees a good deal of its time being street driven and only ventures onto the track a few times a year.

[Alex]

mine will be mainly street and the odd drive up the a66 / m6 once or twice a month

[Turbo-Brown]

Throttle body setups arn't cheap, £1700 potentially on a 4cylinder engine once you have considered custom management which it 100% needs. Its an investment that we may eventually do on the mi16, fancy making me a set Alex!?!

Like these you mean:



Pretty sure I've still got the drawings for them!

[hoshy]

. And you can't get cheaper than free.

You can if you sell all the extra stuff that you don't need and then your effectively being paid to make your car go faster

[hoshy]

Like these you mean:

Hope you plugged that coil pack back in at some point

[Jon_Bmw]

Mmmm, me want!

I'm shocked at the halfraud 'single' leads as well! Oh wait a sec, our king lead happens to be one.

Good point!

Aah that's why it won't run!

Those halfords leads are cack tis true, but seem to work okay. Just have to check the boots periodically for splits that's all

[monkey]

Yeah, just get a chip and sort the handling first. That's what I done along with a few gadgets.

so far... it's
Smoked Headlights
Smoked indictors and side side repeaters
325 oil cooler grille
Anthracite Sport check interior & //M seat pins
Tec 2 'wheel & //M gearknob
13 button OBC
Map light mirror
Rear blind
Power Flow backbox (Supersprint half system on the way)
K&N Panel Filter
M44 timming chain and S50 tensioner upgrade
Superchip and re-map
Heater plate removed
Z3M shortshift
4.1 large case LSD
Bilstein B8s
Eibach springs
M3 control arm bushings
E46 M3 Cab rear top mounts
E46 steering rack
Mintex pads,
Goodridge braided lines
Cruise-control
LED sidelights
4300K HID low&High beams
4300K HID fog lights
Now, it's time to go after that 100bhp/litre

So there's loads of little things you to do before you go in search of more power

Dave you say you put hids in your main beam lights have you had any problems with them as i heard that they arn't much good for main beam lights as the switching between hi and low shortens the life of the bulbs

So you want your M42 to go faster.........how about turning your M42 into a 2.1 stroker turbo!

The M42 is called the baby M3 engine and can be tuned a lot further than was BMWs intention and if you know what you are doin a lot cheaper than dropping in an M3 engine!

What you need is a BMW M47 diesel crank, con rods and race pistons.....oh and a turbo ....... OVER 200bhp and a lot lot more torque!

Check out what these guys are up to .....:

Who calls it the baby m3 engine?

Baby M3 is a pretty popular name for the iS so it logically follows that the engine could be referred to in that way.

[Alex]

another name is the poor mans m3

[ShepsEvo3]

Ooo... just seen this thread, how slow am I? lol

Actually, 45's would work on an 1800, especially a multi valved engine like the 318is, but everyone is right in this case, you will loose driveability. You will turn your current 3D igntion map into a 2D map also, unless you can hook up the standard TPS which is a throttle potentiometer on the M42, upto the carbs. Also, to keep the ECU happy, you would need to fit an intake temp sensor, which isn't a big deal. What faults the ECU will throw out with no injectors linked up I have no idea, not to mention the lack of AFM. Would put it into a limp home mode and the ignition timing would probably be retarded more then you would want by then too.

Having said this, if you can map the ignition, port the head, fit some lary cams and get the carbs set up properly ;) It would actually be quite a fun car.

It isn't actually that cheap a conversion either, so best to just remap what you have and be done with it.

There is so much in that statement that's just bollocks, in fact I'm not sure that there's anything that isn't.

You don't happen to write eBay adverts do you?

With that crank and race pistons with higher CR with nicer cams and a tidied head, you wouldnt need a turbo to get over 200bhp ;)

With a turbo, correct CR and cams with work on the bottom end too, you could easily double that figure.

I thought that exactly, if I built a motor of that spec I wouldn't be happy with anything under 300-350bhp.

But as for it being cheaper than dropping an S14 in, you've got to be joking right?

Well, whats an S14 worth these days? £1500-£2k, then the wire loom and ECU, add another £200ish, then there is the exhaust, etc. So close to £2750 I suppose at the max.

If you know an engine builder... I guess something could be built up for reasonable money.... but to Mr average it wouldn't be cheap.

[Dave_M3]

With a 2.1 M42 with proper race pistons coupled with a turbo and maybe a set of ITBs thrown in the mix, 600bhp wouldn't be totally unrealistic.

Why you would want 600bhp from a M42 in an E30 would be another question however

I reckon 180-220 would be just nice for an iS as an alrounder,
But after everything else is sorted.

No point in having that 4 pot handling if all the suspension parts are all tired and sloppy

RE: Monkey; Yeah, I fitted a kit from Evolve in the main beams too and although they do take abit to heat up on intial turning on from being off for a good bit and taking 2 or 3 seconds when after dimming for lines of traffic I find them great.

I have had them in for nearly 6000 miles now and they are showing no signs of burning out or becoming dull etc like I've heard people saying about fitting them in the main beams.
