Hey everyone, here's my 89 E30 M3 2.5. I've had the car for about 6 years now and it has gone from a regular M3 to a fire-breathing monster.

I'll begin with the motor. It started out as a 2.3 with 196hp, but it is now stroked to 2.5, and makes around 275hp. I'll just list the mods - it's a long one: E3 crank, Ross 11.25:1 pistons, Total Seal rings, Pauter rods, E3 AFM, E3 48mm throttle bodies, E3 injectors, Cosmo adjustable fuel pressure regulator, E3 header, Don Fields ported head, Schrick 284/276 cams, Turner cam gear, E3 valve springs, Titanium retainers, Turner 8lb flywheel, Sachs HD clutch. I just installed a new Raven exhaust system consisting of dual 2.5" stainless pipes resonators and mufflers (all straight-through) from the header back, giving me a very noticeable increase in power throughout the band!

Now that the exhaust system is done I am looking forward to my next engine mod, a Maxx Alpha-N intake system. This amazing unit consists of a piggyback computer system that ditches the AFM, leaving only an air filter between the outside air and my throttle bodies. This also uses a 2-piece carbon fiber intake chamber that reaches to the front panel of the engine bay to pick up its air from the bumper inlet. Giving around 30-40 hp This should bring me past the 250 rwhp mark, and over 300 crank horsepower out of my NA 2.5l 4 cylinder. Further down the road I would be able to change to wilder cams due to my increase in low-end torque, possibly a schrick set in the 320-305 range. The only thing left to do from there would be a custom ignition system, but I'm not sure if that is entirely necessary yet.

I have done extensive modifications to the rest of the car as well. I'll just list them off:

For my suspension I chose the Turner Motorsports J-Stock kit as it is a proven track system. It includes high-rate H&R springs and custom valved Bilstein and Rancho racing shocks. Suspension Techniques adjustable swaybars keep it level while adjustable camber plates and offset strut mounts make the front end bite. Aluminum rear shocks mounts, urethane and delrin bushings and all necessary e30 reinforcements help make the whole package drum-tight. The suspension definitely helps to keep all of the power under control, but the brakes needed some work too. I installed OE BMW rotors (cryo-treated by frozenrotors.com) and Porterfield R4 pads for friction. I also use AP 600 fluid and installed Fischer stainless lines and a 25mm master cylinder for better feel as well. That pretty much rounds out the performance mods.

Inside I started with the safety mods, I needed new seats badly so the stock Recaros were swapped for Konig SK5000 adjustable seats. Ultrashield harnesses keep me in place, and because of the harnesses I needed a rollbar, the 4-point from Autopower worked out well for me. I ditched the stock wheel for the nice E3 suede unit, and installed an E3 shift boot and e-brake handle to match. White-faced gauges with a higher 8000rpm redline were necessary for the new motor, although the 180mph speedo is a bit optimistic.

I have always been a car audio fan, so I couldn't leave it much alone. AT one point I had this huge system in there, but now it is out to make the car closer to a race car. An eclipse 8440 was the head unit now, with the Command control unit and hands-free navigation system attached. A Clarion VMA-7191 7" widescreen monitor sat in the front of the console, the pod molded out of bondo. Each door had Boston Pro 6.5-3 components in custom speaker pods that mount where the factory map pockets were located. You can see the wireless RF remote for my PS2, flushed in the front of the amp rack panel between the seatbacks. A JL Audio 300/4 powers the front 3-ways, while a JL Audio 500/1 powers the Alumapro Alchemy RX 12" subwoofer in the trunk, ported through the ski pass-through. You can see the custom M-colored vinyl in the rear amp rack cover.

Outside, the 18x8 M Parallels (OE on E39 740i Sport) are wrapped in 225/40ZR18 Toyo RA-1s to set off the stance and stick like mad at the track. The front bumper is a lightweight cover made by Vladen that uses an integrated Evo2 chin, attached to a carbon fiber front splitter. Then, a carbon fiber and urethane hood took 50 pounds off, as well as another 30 or so off the back with a carbon fiber Evo 3 replica wing. Carbon fiber DTM style mirrors saved a few pounds and look amazing (not in pics, sorry), and I used clear indicators and painted the taillights red as well as changed the emblems to red to finish it off.

As always, the M3 is a work in progress. This pic is from when I had the frontend, hood, spoiler and sideskirts resprayed. You can see the stock M3 bumper too. I actually drove the car like this for a week waiting for a part to come in to fix my 318 - Talk about a head turner! This car is an ongoing process, but besides the Alpha-N system and cams I can't see much else for it, but I'm sure I'll come up with something;)

And last but not least, my title as #1 ride:

Check out my garage, I have 3 other rides that are worth checkin out.
