Project E46 M3: Part 18 – Project M3 vs E90 M3 V8

By Pablo Mazlumian

We were pleased with our S54 3.2-liter in stock form, and the goal was to bring it up to V8 M3 performance. Was a 12% power improvement and 90-lb fat reduction enough? Find out inside! We test them to speed and in the quarter-mile. We also compare them from 30-100 MPH in third gear to compare low- and mid-range torque for you track guys! And why not--we even throw in a Mustang GT 5.0 in there...


 

Project E46 M3: Part 17 – The preferred exhaust setup and more AEM tuning by MKC

by Pablo Mazlumian

Life would be a lot easier if we'd stayed with the stock headers, but when we tested our VAC headers in Part 3, the increase in power was too much to let go. Since then, we've tried different header-back systems but they either were too loud, droned at low RPM, or didn't fit all too well. Today, however, we think we've found something that works great and doesn't break the bank. Dynos graphs and video clips inside!


 

Project M3: Part 16 – Koyorad All Aluminum Radiator Installation

by Pablo Mazlumian

Until now, Project M3's benefitted from increased power, braking, and handling performance, as well as nice improvements to the interior and exterior aesthetics. But keeping things cool under the hood is something we haven't touched on yet, and we do so today with an all aluminum radiator from Koyorad!


 

Project M3: Part 15 – More Exhaust Testing and Weight Reduction

by Pablo Mazlumian

We test a new exhaust system and drop some weight in the process. We've got dyno graphs and videos in this one. Plus, we check out dad's new 8-Series BMW and drastically change its looks with a simple wheel upgrade. Check it out.


 

Project E46 M3: Part 14 - Short Shift Kit and Lightweight Clutch Testing!

by Pablo Mazlumian

We not only install one of the best short shift kits money can buy, but also test a lightweight clutch and flywheel--on the dyno! How often do we see publications spending the time doing that? Does it make a difference? We answer that here, plus we check out a supercharged E46 M3 racer that rolled into Modified by KC's shop that day!


 

Project E46 M3: Part 13 - Lightweight clutch and flywheel, and more!

by Pablo Mazlumian

Our E46 M3 is really coming along. In the power department, in order to get significant gains we're pretty much at a point where we either need to get into the motor, or go forced induction. However, a clutch and flywheel is one way we can get more out of the already existing power. In the next two parts we install and dyno test a Clutch Masters FX400 clutch and lightweight flywheel, and show you several other products we used to drop more weight for additional overall performance.


 

Project E46 M3: Part 12 – Whiteline Front Control Arm Lower Inner Rear Bushing, Alignment, and Tumbler Switch fix

by Pablo Mazlumian

It’s hard to believe that nearly an entire year has gone by since we’ve last updated Project E46 M3. The car's been running great, and the 320-plus WHP normally-aspirated S54 six-cylinder never ceases to amaze. This time we enlisted Whiteline for its drop-in, lower inner rear bushings for the front control arms, and performed a quick fix to the steering column. We also got an alignment at a very unassuming shop with interesting machines inside! Take a look.


 

Project E46 M3: Part 11 – Castro Motorsports Intake Manifold Installed and Dyno Tested!

by Pablo Mazlumian

We install and test the Castro Motorsport CSL-style airbox on the dyno with video clips of the new sounds.  We also get to check out a couple more of Modified by KC's projects, including one of the baddest BMW 335s in the country!


 

Project E46 M3: Part 10 - Exterior Upgrades For A Cleaner Look

by Pablo Mazlumian

Take a look as we enhance our E46 M3's appearance with a new carbon fiber splitter, carbon fiber rear diffuser, and a plethora of underside neon lights! (think about what day it is before you flame us).


 

Project M3 Part 9: Simple Interior Upgrades

by Pablo Mazlumian

A big part of the driving experience is in your surroundings inside the cabin.  With about an afternoon's worth of work, we show you how we tastefully transformed the look inside Project E46 M3's cabin.



 

Project M3: Part 8 - Dealing With The Dreaded EML Light

by Pablo Mazlumian

If you've ever had the yellow EML light come on, it usually has to do with the drive-by-wire system.  In Project E46 M3's case, every time it came on, it would stall the car and render it useless unless you knew what to do to reset it.  Check out what we did to get the car running tip-top again.


 

Project E46 M3: Part 7 - Magnaflow vs. Corsa Cat-back Exhaust Systems

by Pablo Mazlumian

We install a Magnaflow system in hopes to quiet the car down a little further, given car's cat-delete setup.  Find out how the test goes--with video included!


 

Project E46 M3: Part 6 - We install the AEM Infinity Engine Management System!

by Pablo Mazlumian

At the heart of any engine is the engine management system.  We install AEM's latest and greatest and are blown away not only by the performance, but by all of the features that transform this car into so much more!


 

Project E46 M3: Part 5 - Bigger Brakes all Around

by Pablo Mazlumian

In Part 4 we witnessed an aesthetic transformation and a dramatic improvement in all performance categories, especially braking.  Going from 60-0mph in 10 less feet, or experiencing a 0.14G improvement in deceleration, after all, is hardly going to go unnoticed.  What will go unnoticed--until pad failure or fluid boil--is the increase in heat throughout the brake system, which we tackle next!

Project E46 M3: Part 4 - Improved handling, acceleration, braking and looks!

by Pablo Mazlumian

We test a wheel and tire package with eye opening results!  The M3 is now quicker, handles better, stops on a dime, and also turns more heads.  Check out our numbers!


 

Project E46 M3: Part 3 - Headers, software, dyno testing and more!

by Pablo Mazlumian

Aspiring to achieve 100whp/liter from this 3.2-liter, we put more performance upgrades to the test on the dyno and in real world performance situations.  If you like dyno graphs, acceleration times and videos clips, this is a must read!


 

Project E46 M3: Part 2 - Cat-back Exhaust and Pulleys

By Pablo Mazlumian

In our quest for an all-motor 100whp/liter, we install and dyno test a cat-back exhaust and under drive pulleys from industry leaders.  How much power do you think these upgrades provided our M3?


 

Project E46 M3: Part 1 - Dyno and Acceleration Testing

By Pablo Mazlumian

It's raining BMWs at MotoIQ all of a sudden.  Introducing our next project, a 2002 E46 BMW M3 with a six-speed manual gearbox, and an engine rated at 333 bhp and 262 lb-ft of torque from the factory 3.2-liter inline-six.  It's dirty but it's also silver so who cares.  In Part 1 of our project we take our bone stock M3 and already start running it through a series of acceleration and dyno tests in hopes of extracting a normally-aspirated 300 whp from the 8000 rpm 3.2-liter.
