IS is a coup, both both have i6 engines around 190 HP, however the 328 has much more torque. The 325 was produced from 92-95 and has a 2.5L engine. The 328 went from 96-99 with a 2.8. Appearance differences include body colored bumpers and rocker panels, as well as more rounded kidney grills on the 328. The interior of the 328 has digital climate control wherease the 325 had manual.

the bodies are the same, they are both two doors, the 325 is a 2.5 liter inline 6 cylinder, the 328 is a 2.8 liter inline 6 cylinder, the 325 has 189 hp, and the 328 has 190 hp, but the 328 has about 17 lb/ft of torqure more than the 325 i believe, the 328 is the faster one, but other than that they are very similar..

thanks guys...which has more of an aftermarket?
does the 328 weigh more? it sounds like the higher the numbers go for models, the more plush the interiors get...lol

OBDI will give you slightly more tuner options. Cosmetics are virtually the same. The cabins of the 325 and 328 are also virtually identical.

not sure about the head, but just so you know, you can get a 328 and convert it to a obdI. I actually dropped a 328 engine into my 325is and with a few mods (including the obd1 conversion) it has much improved performance over a 325.....

thats not necessarily a bad thing. the non-vanos 2.5L's are the only 2.5L that can be bored to fit M3 pistons (86mm), it has dual valve springs, the valve stems are 1mm longer, and the valve seats are 32.4 exhaust and 28.8 intake (where as the vanos engines are 28.8 exhaust and 26.8 intake). you can also put the exhaust cam on the intake side and buy only one aftermarket cam to give you M3 spec cams. so with the non-vanos you have the potential to build a relatively cheap 3.0L S50, plus there have been some known cases of vanos failure, which is just another thing to break.

Sorry for being a little off topic guys/ girls.

well basically all you need is to have it bored out to 86mm, use M3 or custom pistons, get a 3L crank, and 3L rods. that will give you a very potent 3L, but there's some more stuff you need to turn it into a US Spec S50

edit: this only applies to non-vanos engines since vanos blocks cannot be bored to 86mm to accomodate M3 pistons.
