| I would like to give my 320i touring a bit (Lot!) more power. Would the 325i engine drop in without too much fuss or would i not notice much of a power increase? |

Not to difficult i shouln't think but i'd just but a 325i get all the extras that comes with one then and probably less problems. -------------

hello window man the fact that you have a 320 greatly simplifys matters. as the lump will drop straight in + plus theres no modifying of the loom. existing g/box can be used, ecu has to be swaped though. the power difference will be very noticable, as opposed to the 32o"s falt power curve. bags more torque too. |

Thanks for the replys! The reason why i do not want to buy a 325 is because i have done such a lot of work on my 320 also it is a manual which i seem to remember being quite rare in the 325 touring. I think i will start looking for a engine + ecu. Hopefully i will notice the power difference! Thanks ------------- Steve Lowe |

hello window man. i understand what you mean. its up to you what you want to do to your car. well worth doing though. where are you based by the way. the reason i ask this is because i break e30"s you see. and i can probably get all the stuff you need. ive just a an 89 325 come in but the engine is pritty much spoken for im afraid.
cheers mate. |

Check the gearboxes first. Some 320i used a Getrag 240/5 (early ones may even have had a ZF unit) while the 325i used a Getrag 260/5. I don't think they are compatible but could be wrong. If you do the change, also consider upgrading to front ventilated brake dics (if you don't have them) - you just need the calipers and discs. |

Thanks for the replys. jonb i live in Leatherhead in Surrey. Where are you? I think i will start looking around for a 325 engine in good nick as i would love to give it the extra umph. When i was looking around for my car i was told by a friend that had both models (320 and 325) and he said their was not that much difference in power but i think he must be wrong? ------------- Steve Lowe |

hello window man im in bristol. about 100 or so miles. ;( the power difference is very noticable, as theres a hike of about 50bhp. worth doing i think. |
