For those on a tighter budget, the base Ford Mustang swaps the GT's 5.0-liter V8 for a 2.3-liter turbocharged EcoBoost engine that delivers a respectable 310 horsepower. While it may have less power than the GT, it's more powerful than the previous-generation V8-powered Mustang. If you want to extract more power from Ford's EcoBoost engine, Roush offers performance kits that provide a marginal power boost.

Alternatively, if you fancy getting your hands dirty and want to work on your own custom Mustang build, Ford Performance is selling a new "2.3L EcoBeast" short block crate engine that gives the EcoBoost Mustang V8 levels of power.

Retailing for $6,485, the 2.3L EcoBeast short block is available for the Mustang EcoBoost and Focus RS and features forged internals. Included in the kit is a deck cooling jacket insert for additional bore strength, a Callies forged crankshaft that is nine pounds lighter than the stock crankshaft, Callies Compstar H-beam connecting rods with ARP2000 rod bolts, and Mahle forged 2618 pistons that provide a 9.5:1 compression ratio.

The kit also includes an oil pump, chain drive, damper bolts, oil filter, and head gasket. If you want to install the short block in a Focus RS, the Mustang motor mount bosses can be removed.

Ford has tested the EcoBeast short block to handle up to 500 horsepower and 415 lb-ft of torque. The kit is compatible with 2015-2022 Mustangs with Ford's 2.3L EcoBoost I-4 and Focus RS models built between 2016 and 2018. While Ford's EcoBeast engine gives the base Mustang V8 levels of power, there is a downside, however.

Ford stresses the performance part is intended for "competition use or off-highway use only," making it unsuitable for public roads and highways since Mustangs equipped with the 2.3L EcoBeast engine may not meet emissions regulations in the US and Canada.
