E30 318iS Tuning(need 180bhp)

When i said non of the M3s made 100bhp / litre i was only thinking in terms of E30.

Many of the UK spec E36 M3 Evos don't actually make the quoted 321bhp. Apparantly this is due to a revised manifold shape to accomodate the steering column on RHD cars, which isn't ideal for cylinders 4, 5 & 6.

Alright m8. 

'fraid not Paul. It was a modified M88 engine with 2 cylinders removed like Sohlman sez.

If i remember correctly, the mpg gauge and speedo are connected and not the rev counter therefore the fuse associated with these should be OK.

The haynes manual for the E30 has pretty good circuit board schematics so you could possibly trace all the electical faults back to a relay or the like. 

Have you updated your speakers as well as the stereo? if so did you have the square pioneers fitted on the parcel shelf and what did you replace them with?

Hey Bob,

The block was from the M10, and the head was from the M88/S38 engine designs.

I just finished fitting my new stereo / speakers.

The original speakers were the pioneer ones (13cm front / 16cm rear ).

I replaced them with 13cm Infinity Kappa Components in the front and 16cm Infinity Kappa 2way coaxial in the rear and it sounds great. Better than my las car with half the speakers (E30 has good acustic dynamics).

Just need to find a place to hide 2 x 1" thick power/earth cables through to the boot. Any sugestions please as i don't want a bulge under the carpet.

Hi all,

I am new today to the boards.  I have a 318iS L 1994.  I have 18" 's on the car ond the look the b***ox.

See ya around

Hi all,

I've had my E30 318is since April 1997, and I'm thinking it's time for a change - if only because I want an E30 in Lachs Silver as opposed to Diamond Black !

I've been thinking about either a mint, original and un molested 325i Sport, or a similarly mint 320is. (I favour the latter for rarity) It's a shame thought that the 320is doesn't have the distributorless ignition system of the 318is, as the latter gives a spark that (in theory) is 3 times stronger than a conventional system. 

I've been reading the pages in the forum, especially on the subject of chipping and wheels / tyres.

Firstly, I looked at the possibility of chipping my 318is. There are performance chips, available from people like Superchips, or Van Aaken Developments, but also "drivability" chips from Star Chips, available through Brodie Britain Racing, in Brackley, Northamptonshire (01280 702 389). Theses chips are designed to flatten the torque curve, making the engine more flexible. This means more torque in the lower part of the rev range, giving better more consistent acceleration throughout. Also they decrease fuel consumption, and also stop the 318is's annoying habit of holding the engine speed at or around 1000rpm while coasting, until the car comes to a halt, when the engine speed returns to normal idling.

Now you may not get a significant increase in power, but they do mean that you no longer have to push the engine speed as high to get maximum torque - and it's torque that makes a car accelerate as opposed to power.

Secondly, on the subject of wheels and tyres, my 318is has the 14" BBS Cross-Spoke alloy wheels, and over the years I've run a number of makes, including Yokohama, Continental, and currently Fulda. My point is that 195-65 / 14 is an unusual size, but I havent found that I'm limited only to budget tyres.

Finally, has anyone here imported an E30 320is ?

I did think about getting someone to find and import one for me, but it seems that the cost of that is more than the cost of the car itself !

Does anyone have any ideas about where to start looking for one ?
