2200 Sport Engine A must for the BMW Driving Enthusiast who wants an increase in performance at a cost effective price. The 2200 Sport Engine offers the following advantages: (Click on M10 Engine Spec Chart above, to see the Chart)
- A sizeable increase in performance
- Excellent engine longevity
- A modernized engine with many mechanical upgrades
- No lose in fuel economy
- Passes emission tests
- Smooth idle compatible with 2 barrel carburetors, tii Kugelfischer, Fuel Injection, C.I.S. or L Jetronic
- Little to no tuning required
2300 Rally Engine This engine is totally streetable but is designed for a more aggressive driving style. It is an excellent choice for hard street driving, auto crossing or driver’s schools. Displacement is increased by stroking the engine with a modified 2.3 liter/S14/84mm crankshaft. The total reciprocating mass (piston and rod assembly) is 4 lbs. lighter than a stock BMW M10 engine. Not only does the lightweight reciprocating mass help this engine to spool up quicker but it reduces vibration at high RPMs and adds longevity. This engine is generally meant to run with no air conditioning but for an additional $500, we can install the AC pulley. Currently our most popular engine, a great “bang for buck” designed for the week-end warrior who enjoys Driver’s School events.
2400 Rally Engine A lighter longer stroked crankshaft is added to this engine – the Evo M3/2.5 liter 87mm crankshaft. If you desire the Biggest most powerful street/track engine that we offer in an M10 Engine – this is IT! The 2500 comes with a broad power band. In a track event such as a Driver’s School, this engine spools up quickly and then pulls hard of corners as well as down the straight away. When on the street – it’s the hottest we make – Period!
ALL our Sport & Rally M10 Engines have the following mechanical upgrades —
- Machined and hand ported head with 21% to 24% flow increase.
- Surface Turbulence treatment to the Head reduces detonation, virtually eliminates head cracking, results in greater fuel economy and lower emissions.
- Sport Camshaft that offers good idle and driveability.
- Single Row Timing Chain for increased life and less parasitic loss.
- Rocker Arms: inspected and 30% stronger than stock.
- Lightweight “Bee Hive” Valve Springs & Retainers to reduce Valve Train load.
- Manganese Bronze Valve Guides for tighter valve stem – to guide clearance and extended guide life.
- Moly Top rings and 3 piece Oil Rings for good oil control & long life
- Rally Engines have special Heavy Duty Tri-Metal rod bearings.
- Blue Printed Oil Pump with bronze pressure relief valve sleeve or aluminum body oil pump. For greater oil pump life and improved oil volume.
- Horizontal Oil Baffle in the Oil Pan, to prevent oil starvation under hard cornering.
- Optional Windage Tray/Scrapper Bar for even more oil protection under hard cornering. Strongly recommended for Driver’s Schools. Additional $350
2200 & 2300 FI Engines These engines, designed specifically for boost, are capable of the high 200 and 300 HP range with as little as 10 – to 12 lbs. of boost. Built tough to take boost pressure and the additional heat and pressure generated in the combustion chamber. For example, from the Ceramic Coated piston through to the Forged Chrome Moly Crankshaft, these two are seriously beefed up. Both engines are virtually identical except for their stroke. The 2200 FI Engine has an 84mm Stroke whereas the 2300 has an 87mm stroke making it the most powerful M10 engine we offer. To avoid any confusion, Metric Mechanic does not sell the Boost System itself or provide the Tuner. We build the engines that can take it.
In addition to the above modifications and those included in our Sport & Rally Engines, all our Forced Induction Engines offer the following upgrades.
- S14, 84mm Chrome Moly Forged Steel Crank for the 2200 Forced Induction Engine or the 87mm for the 2300 FI Engine.
- Stronger “H” Beam rods 565 grams have 4 oil squirter grooves located at the big end to cool off the piston and lubricate the piston skirt.
- Special coated tri-metal rod bearings.
- Special Forced Induction Forged Pistons. Ceramically coated Piston Crown is 2mm thicker than in the Sport and Rally Piston.
- High Silicon Content Alloy (13%) for tighter cylinder wall
- clearance, greater ring and groove life, & minimize skirt scuffing.
- Lower placement of the top ring groove to protect the compression ring.
- 4mm oil ring for excellent oil control.
- Over-sized 23.5mm Wrist Pins, 115 grams.
- The oil pump delivers 20% more flow.
- All Forced Induction M10 Blocks are ultrasonically tested and hand selected for cylinder wall strength.
