  • 1986 BMW E30 M325i - S14B23, M3 interior, M3 suspension

    This thread will serve as a guide on how to not only ruin a perfectly original and rare car but also a reminder to build a car of your dreams.

    Background

    This is my 1986 BMW E30 M325i. In right hand drive countries, BMW released these special models to fill the gap that was created as a result of the left hand only E30 M3. In the United Kingdom they received the 325i Sport, in Australia we got the 325iS and South Africa was blessed with the 333i, 325iS Evo I & II. New Zealand was delivered with a car was was marketed as a M325i and like their UK brothers, the early model sporting the Mtechnic 1 body kit was sold for only a very limited few months before being replaced by the horrid Mtechnic 2.

    Summary

    In my years of E30 ownership and hording, i was fortunate to obtain a 86,000km S14B23 out of a 1988 E30 M3. Since then i had always imagined what it would be like if BMW had created a early model 320iS with the Mtech 1. This small dream has since become a reality when i acquired this factory built M325i. It had absolutely everything, shadowline trim, black headling, houndstooth interior, limited slip differential and the beautiful mtech 1 exterior. I had spare g265/6 gearboxes from old E28s that i had parted, a Z3M diff cover, E30 M3 houndstooth interior and also a small diameter 370mm Mtech 1 steering wheel. Yesterday I acquired a genuine E30 M3 cluster and a full E30 M3 suspension to convert the car to 5 stud like the SA 325iS Evo's.

    Now that we have absolutely everything ready to go, im ready to document this build and i share it with a community that will appreciate this build.

    Here is some of the parts that will be installed.

    One of the first modifications I did was installed the E30 M3 euro front grill which which has a larger opening to allow for more air to reach the intake.

        Hi,
        Interesting project look forward to see how it is coming along, did you find all the parts in Australia or did you import them.

          Wow look's exactly as my 86 M-tech 1 did way back when reason for my screen name. Really liked the ROW body styling vs NA big bumpers. Look forward to more updates.
          Who knows where I'll be, changes from day to Continent.

              I've been fortunate to find the majority of parts locally, which isn't usually the case. Loom and ECU I sourced from America and both M3 Interiors I actually flew over to Auckland for a few hours and collected myself! The car was already exported to Australia in the early 2000s and the motor came out of a car in Sydney that had an Evo spec motor replacement.

                    Making some more progress with this build. I sold my S14B23 as I was fortunate to find a completely rebuilt S14 stroked to 2.5L using the Turner Motorsports kit. Head has been ported, oversized valves and 48mm throttle bodies. This motor needs a set of hot cams, a CF airbox and a stand alone ecu before I can have it installed.

                        Nice, I like the concept here. Not sure I agree about MTech 2 =). I am looking at picking up an M20 MTech 1 in the near future - I do like em

                          LOL yeah I am with you I'm not sure I can get onboard about the "horrid" MTech 2 body, I happen to like it alot more than the MTech 1 myself, but I may also be biased

                            My 2c worth also - keep the M20 and bits if you can - it's nice to have the option to revert to original, and a nice 2.8/9 would be a lovely little MTech 1 road car (even more similar to the 325iS).
