    Hey, not long joined up here..

    Ive got a mint condition E36 M-Sport.. which i previously before being had been looking for a M3 bud hadnt found the one i wanted I.e MEGA CLEAN!!

    so i got the M-sport instead and will have funds soon enough so as a still cant find the M i want i have been thinkng of doing it to my current car as the shell is mint..

    What is all involved in doing so ?

    Or im thinkng of just going out and buying a E46 m3 instead..

    Thanks Roddy.

    it is possible but its a big job
    as well as the usual engine, gearbox rear diff etc you will have to weld in strengthing plates on the shell (i think you can get these from bmw though)
    you will have to make sure you get the ecu, ews and the keys from the same car or it wont run as they are all coded, you will need to do a bit of modifying to the wiring harness to get everything to work as well
    speak to forum member RYM he has done this exact conversion on a 1992 318iS and into 325tds touring also he is a wealth of knowlege on this conversion

    Thanks buddy,

    I have a fair idea how to go about it as ive done a few engine conversions on other cars, get the usual problems like coded keys and such like,

    So not realy much more work than normal to any other car i wouldnt think..

    I will give him a shout tho and pick his brains about the conversion.

    thanks

    Can't really help on the technical side. But I would rather engine swap into a mint car instead of sorting out a bucket with body work issues and god knows what else wrong. The pros of the the swap as well is that you can make sure everything is working and in tip top condition at the time of the swap.

    Hope that's of some use mate.

    Unfortunatly mate there is lots of cars as clean as yours......but 10/10 for self pride.

    Bit of info:

    This topic has been discussed on many occasions which is why a "Sticky Thread" has been created.

    An engine conversion is often the Best Value For Money when trying to squeeze more hp under the bonnet of your BMW..


    What engines produce good horsepower???

    Here are figures for the E36 3 Series to give you an idea of power increases.

    MODEL YEAR BHP

    316i 1990-98 102
    318i 1990-98 115
    318is 1991-95 140
    318tds 1995-98 90
    318ti 1994-96 140
    320i 1990-96 150
    323i 1994-98 170
    325i 1990-94 192
    325td 1993-98 115
    325tds 1993-98 143
    328i 1994-98 193
    M3 1992-95 286
    M3 EVO 1995-98 321


    What parts are required?

    There are factors to consider when choosing a replacement engine.

    Firstly you need to know if the car you have and the engine you have chosen has EWS.

    What is EWS?

    See the attached document here...... EWS.pdf

    If your EWS systems match then the parts you require to get the engine working will be:-

    Complete engine

    Engine loom

    ECU

    If your car is EWSII you will need additional parts:-

    As well as those listed above you will need... Transponder key, ignition barrell and EWS module. Your car will normally have EWS is it is a 1996 Y.O.M (year of manufacture) or later..


    Other considerations:-

    When increasing the cars performance you should consider the uprating of:-

    Braking System

    Suspension

    Prop, Differential, Drive Shafts, Bushes and Engine Mounts.

    What if the EWS systems are different?

    This is a common mistake.

    I performed an engine conversion on my own 1992 318is 16v Coupe.

    I replaced the engine with an EWSII 1995 3.0 24v Motorsport engine.

    Here are the parts I had to replace to overcome the problem...

    Complete Engine
    Engine Loom
    ECU
    Complete Car Loom
    EWS Module
    Transponder Key
    Transponder Ring
    Ignition Barrell
    EWS Transmitter
    Steering Column
    Brake, Discs, Pads, Calipers and Hubs.
    Suspension (318is struts pushed the front wheels too far towards the front bumper)
    Gearbox
    Prop
    Differential
    Diff Housing
    Engine Mounts
    Chassis Reinforcing plates for Gearbox and Diff housing
    Exhaust Manifold
    Exhaust System
    Drive Shafts
    Suspension Bushes

    When replacing a 4 cylinder engine with a 6 cylinder you will also need to replace the instrument cluster.


    Where can I obtain the parts I require?

    http://www.beemer-redeemer.com/index.html
    http://www.bmspares.co.uk/
    http://www.fabdirect.com/index09.htm
    http://www.quarrybmwspares.co.uk/
    http://www.m3spares.com/

    These Breakers were not listed in any particular order... Contact them all to get the best qoutation


    What do I need to consider?

    Most importantly........... COST!!!

    Is it cheaper to buy a more powerful car?

    When I was asking for information on my conversion on other less informative forums I was disgusted to hear "Just go and buy an M3"

    They were missing the point, my car was already completely modified. It had been featured by PBMW magazine and Redline magazine and was just in need of extra hp!

    There was no way I was going to consider selling my pride and joy that I'd spent many thousands on just to buy a bog standard M3 and have to do it all again.

    I'm sooooo glad I found the parts donor car (a damaged E36 M3) for £1800. The problem was that a parts donor doesn't give you all the parts you need and causes further costs.

    My car has cost me thousands of pounds more than it's value but i'm happy. It's unique and to me that's what modifying is all about.


    Yes... I could have Turbo'd or Supercharged my original engine but it would have cost me thousands more and probably still wouldn't get near to the 286 normally aspirated horses that I have galloping under the hood!


    I hope this helps you guys (and girls) and I certainly hope it reduces the number of questions we have regarding this conversion..

    PS Information is available on how to get around the EWS system but it will not be posted willy nilly for all to see. It will be disclosed to only those that are in Dire Straits AND genuine modifiers

    But I don't want to go to the trouble of an engine swap! What other modifications are possible?

    There are a variety of modifications that can performed on your existing engine in order to gain extra BHP and torque. But when you are starting out with an NA (naturally aspirated) engine (e.g. non turbo) the gains are minimal in real world terms.


    Modifications Include:-

    Air filter replacements and Induction kits (the merits of these are dubious and we would not advise removal of your stock BMW airbox or filter...as performance can and does suffer)

    Performance Exhausts - Always a good option

    ECU chips/remaps - if done by the right person/company, a very good option for more power.See the ECU forum for more detailed info.

    Supercharger/Turbo's - See the relevant subsections for these conversions. But beware, they are EXPENSIVE and for a lot of BMWs a lot of custom fabrication and parts making is needed, hence the high cost.

    Electric superchargers and 'power valves' - ONLY mentioned here to warn you NOT to buy or fit these complete junk items.

    The BMW is very well catered for by aftermarket manufacturers. The problem being that the gains expected and the gains acheived are more than often not matched and cost per hp is much lower in many cases to drop a larger sized engine in.

    Beware though, unless an engine swap is declared to your insurers (and the DVLA) you will effectively be driving uninsured and should the worst happen (and you kill or maim someone) you will be in a whole world of pain (and prison). The same goes for some modifications if undeclared.

    i had looked and did search's i couldnt find nothing on this forum mate thanks,

    as for how clean my car is, im not just saying that because its mines ive never physicly seen one in as mint condition as mines even at shows.. hence why i dont want to buy a M3 on a L plate for example that needs rear arch work and such like,

    What EWS's system would be on my M-sport?

    Thanks for the info..

    Your car is a standard 318iS with some bits and pieces on, so it will have the standard 318iS EWS.

    You will need to purchase the whole list of things RYM put:

    Complete Engine
    Engine Loom
    ECU
    Complete Car Loom
    EWS Module
    Transponder Key
    Transponder Ring
    Ignition Barrell
    EWS Transmitter
    Steering Column
    Brake, Discs, Pads, Calipers and Hubs.
    Suspension (318is struts pushed the front wheels too far towards the front bumper)
    Gearbox
    Prop
    Differential
    Diff Housing
    Engine Mounts
    Chassis Reinforcing plates for Gearbox and Diff housing
    Exhaust Manifold
    Exhaust System
    Drive Shafts
    Suspension Bushes
