"M50B28" refers to an engine created from M50B25 head with M52B28 block, or an M50B25 with M52B28 rods and crank. This produces an M50 that is superior in power to a stock M52B28 or M50B25.

==Intake==
The most basic build uses an M50B25 and replaces the stock crank and rods with M50B28 crank and rods. There are many variations upon this build and each will be outlined in the future as we are able to complete these pages.
For most Stage 0.5-1.5 M40, an upgraded drop-in filter is usually perfectly fine and offers a similar power gain to a full intake system. At higher power levels, upgrading the intake system will be more worthwhile.
 
==Exhaust==
The stock exhaust manifold is relatively good for OE. Upgrading this component is still a worthwhile investment, and can reduce weight, temperatures, and increase overall engine efficiency.
 
A cat-back exhaust offers the least gains in comparison to intake and exhaust manifold. 57-76 mm (2.25-3 inch) diameters are ideal, though there is minimal difference beyond 65 mm (2.5 in) diameter at lower modification levels. Please consider the weight difference to power gain and decide what works best for you.

Upgrades

Intake

For most Stage 0.5-1.5 M40, an upgraded drop-in filter is usually perfectly fine and offers a similar power gain to a full intake system. At higher power levels, upgrading the intake system will be more worthwhile.

Exhaust

The stock exhaust manifold is relatively good for OE. Upgrading this component is still a worthwhile investment, and can reduce weight, temperatures, and increase overall engine efficiency.

A cat-back exhaust offers the least gains in comparison to intake and exhaust manifold. 57-76 mm (2.25-3 inch) diameters are ideal, though there is minimal difference beyond 65 mm (2.5 in) diameter at lower modification levels. Please consider the weight difference to power gain and decide what works best for you.

Head

Camshaft

Read the camshaft page for more information.

Valvetrain

+1 mm oversized valves are a worthwhile upgrade. If you plan to rev high, the most important upgrades are valve springs and rockers.

Block

Pistons

Crank/Rods

Forced Induction

You can expect between 6-10 Hp per pound of positive pressure added for most forced induction setups. All M40 variants are able to handle 6-8 PSI relatively well without any internal modifications. With just ARP head studs and a quality head gasket, an otherwise stock M10 can handle 12-15 PSI relatively well.
