E30 325i, what are some easy tunning tips?

[tcleyton]

Just wondering if there are any little tweeks one can make and where you would start if you had a standard engine to work with?

[MattTheHat325]

First thing to do mate is make sure the engine is bang on, fresh oil service, new filters, valve clearances spot on, injectors cleaned, make sure there are no splits or cracks in vacuum hoses and intake elbow, get any sensors checked out/replaced if needs be. This will be far more beneficial to your cars feel and performance than bolt on mods.

Once you've got it up to scratch the worlds your oyster really mate. How much do you want to spend? And what sort of use does the car get? road? track? etc

This covers it nicely..

Then this;

No really simple,cheap performance gains,exhaust manifold and aftermarket cams are available,and a capacity increase will help.

In general,every 10bhp from the stock 171bhp will cost about £1000....

[Speedtouch]

A chip will in most cases provide a useful gain in power/torque and driveability.

The ones I can provide give the following gains:

EcoTorq M20B25 Mild; 7-11bhp gain, significantly enhances the torque for driveability/improved fuel economy (expect at least an extra 2-3mpg average) and eliminates flat spots, also a 6900rpm rev limit. An ideal blend for daily motoring, also works well with automatics.

M20B25 Wild; 8-15bhp gain, up to 192bhp if combined with 268/268 cam, BBTB and six-branch as per Alpina C2 2.5 spec, 7000rpm rev limit. Best suited for fast road/track day use.

The chips are a doddle to fit (only takes half an hour at most) and is a cheap and easily reversible mod.

[snowmaan]

what sort of priceis the Ecotorq chip?

[Green]

M20B20 320i, M20B25 325i, M30B35 335i Mild/Wild & M50B25 non-VANOS ECU Chips, £35 posted. Note these are not Zone chips.

The mild and wild both make quite a difference

[Speedtouch]

what sort of priceis the Ecotorq chip?

Just £35 posted within the UK.

Not exactly true.

[daimlerman]

In general,every 10bhp from the stock 171bhp will cost about £1000....

Not exactly true.

Why not?

[bss325i]

In general,every 10bhp from the stock 171bhp will cost about £1000....

Not exactly true.

Why not?

Because you can get a 15bhp gain for £650 then another 10bhp on top of that for £800.

This is on the proviso that the M20B25 is in fine fettle.

[daimlerman]

So for £1450 you can get 25bhp?

That's not far short of my BALLPARK GENERAL fiqure,is it?

I see that you do not include the cost of your Viper chip in your 15bhp claim!

[Jhonno]

Your quote is £100/bhp

Barry's is £58/bhp

So a way off..

No its 25% short of you BALL PARK figure!

WTF are you on about viper chip?!

The PROVEN 15bhp gain is a BTB manfold for £650

The other 10bhp gain for £800 is for a cam (£400) and a remap (£400)

Don't be so bitter!

[daimlerman]

Don't be so bitter!

Wine drinker these days,bitter goes straight through......


So sorry,Barry!

BTW,you were done on a re-map at £400....

I was not "done" on anything as my car has not been remapped. The £400 was for 8 hours labor @ £50 ph. A time of which i was being generous.

The £300 Gunni charges is good value.

It also goes against your "£1000 for every 10bhp"......

[Simon13]

boring.................

Things like valve clearances and spark plug gaps all help with the running of the donk and can influence the idle/power delivery a little. All helps

[bss325i]

As was said in the second post.........

[Simon13]

50% there but no mention of spark plug gapping

[Dezzy]

Wash and polish your car.

Mines always faster when clean.

[bss325i]

Stripes make your car go faster!

[Simon13]

they cause drag due to the thickness of them.

[DanThe]

Fold the rear seats, fit a K&N and run on 1/4 of a tank with a pint of thinners every other day, dont forget to chip off all the crusty bits of bodywork

[bss325i]

But stripes give down force there for increasing your lap time!

[DanThe]

Ravs new excuse....

[bss325i]

Lol!

[Speedtouch]

Also fold in the door mirrors, which will save you approx. 0.00002Cd.

[Simon13]

its santa pod week and the fever of motorsport mods for the glory 1/4 mile times.

[DanThe]

Should I run 3 litres of fuel or fill the tank? Inflate the front tyres and deflate the rears? Or should I take the interior out and be a complete and utter hopeful?

[Brianmoooore]

The OP, a new member, posted a reasonable question in the appropriate forum.
tcleyton, I apologise on behalf of the E30zone team for the way your thread has degenerated, but we are a have a large membership, and in any large group of people, there will be a number of idiots and those who, usually mistakenly, fancy themselves as comedians.
To the guilty parties: Please go and play in an appropriate forum, such as Pub talk or the Kinderkarten.

[DanThe]

Boooooooo,,, Hisssssss,,,,,,,

[Simon13]

Lord give me strength.

[Dezzy]

Surely you want to decrease your lap time?

[bss325i]

Brian, the OP question was answered within a few posts at the beginning of the thread.

I guess someone as boring as you has no sense of humor. Or personality for that matter.

[E30BeemerLad]

Barry, kill the personal remarks please.
