Induction Kit for a ’96 323i Coupe

Actually, I'm older and wiser in the bimmer world since that was posted - differences between the E36 323i and 325i are as follows:

1   323 has an Aluminium block, 325 has Steel block

2   323 has restricted throttle body and traction control thingy

3   323 has single tail-pipe exhaust, 325 has twin

4   323 has a taller gearing ratio, meaning a higher top speed but slower acceleration

5   ECU Mapping

And that is where the 22 bhp diferrence comes from, bearing in mind that they are both 2494cc, 24 valve 6 potters!!!!

I thank you

hi m8 , sorry all about the 2 posts but it didnt show up at first so i rewrote it .

the throttle boddies are the same size on all models 320, 323, 325 , 328.

so is the air filter box on all models including the m3 as i gave my new air filter to my m8 with a m3 and worked perfect.

i have a k&n filter that is for the 325 that was in my 320 for about a month b4 i sold the car that will fit yours, you can have it for a tenna m8 looks unused.this gives about and upto 5bhp ,i used a m3 air conversion on my car, the part from the airbox to the front grills plus a tube down to the brake air cooling vents on the bumper,genuine part from bmw. doubles the air intake.

the chip is different as this is the part that controls fuel air mix,rpm etc.so just get it chipped as a 323 and gives you about 10-15 bhp and about 10% more torque

exhaust ,,, you gonna like this, easy.  the system is the same for the 320 and 323 , but  if you get a 328 cat and back box from a breakers , check probes are in the same place as yours , bingo straight swap as the headers are all the same size, you get better flow though the twin cat and twin tail pipes .you should get around another 4 to 8 hp from this too .

just to round it up

airbox 5 bhp  exhuast say 5 hp to be realistic and chip say 10 hp =20bhp plus if you use super or optimax even better.

and all this looks like when you buy the car. mine was still under warrenty

Cheers Skull,

That's interesting, I read on a thread on here that the differences were the throttle bodies, exhaust, chip and the block was steel not alloy.

What do you reckon?

If one were to fit an induction kit to presumably increase the volume of air entering the manifold, would that not lean out the mixture if it were not corrected ?  AND ........how would one correct it in a '93 325i coupe ?

The ECU can cope with any increase in air flow from fitting the kit. It's often recommended that following fitting of a kit, you disconnect the battery for ~1 hour and then reconnect it which triggers the ECU to 'relearn' it's engine ensuring there is no lean running.

Yello,

Yep, I paid £40 odd for a set for the better half's 'scort.

Cheers Malc............

Yello,

This link shows the EBC range of pads for cars.......  I've used the 'Greenstuff' pads before and they are just great.

Cheers Malc.................

Sorry about the bad writing before; very poor Rich...

Thanks for the brakes info Malc; not heard of EBC HH sintered pads.  Can you tell me more?

Anybody else any ideas????

Short answer seems to be that they don't really know.  Partly due to the fact that there aren't that many paople out there with our enigne, and the ones that do don't know the specific differences.

A firend of mine used to work for BMW and was a bit of a tech ehad.  I'll see what he knows when I catch up with him next and let you know if I get anything useful.

So suggestions to the floor.  I have a totally std car on 15s.  Apart from removing the bootlid badge t'other day!  Sbtle performance mod suggestions anyone???  I want to improve my front brakes to, but at a budget(!)  On suggestions as to what performance brakes and pads I should using and what costs?  The Demon Tweeks catalogue just loses me on brakes y'see.

Yello,

Newbie question alert !

"Although the engine is apparently the same as the 325i for which there is an induction kit available, Demon Tweeks tell me that their must be differences, or the manufacturers would sell a kit for the 323i".

I'm trying desperately to find out what difference there is between the E36 325 and the E36 which means that we "only" have 170 bhp and the lucky 325 owners have 192bhp.  Same engine capacity etc.  The 323 is newer and "detuned".

So it SHOULD be easier for us to tune our 323s in the first place.  But 323s are neglected over the 325 for tuning parts generally.  Is it a question of ECU mapping or something else?  Any ideas Grimesj, or anybody else???
