2.4L Features & Benefits

The 2.4L configuration is our bread and butter. It utilizes a 100mm crankshaft, larger bore, and 6mm taller deck to increase displacement substantially.

Included Services

• Engine blocks visit our hot tank and then proceed to rust removal before receiving a coat of black high temp engine paint for a finished appearance.
• Crankshafts are never cut / turned and receive a micro-polish treatment and balancing specifically for high performance applications.
• The machine work process starts with an overbore utilizing a 4g63 specific torque plate to ensure roundness. The overbore is followed with a three step honing process that is finished with a plateau hone for the absolute best cylinder wall finish and ultimate ring seating.
• The last step in the machining process is resurfacing. We pride ourselves on the surface finish (RA) we achieve as it is of the utmost importance in regards to head gasket sealing.

Included Components

• ACL Race series bearings (King XP Series Bearings are also used when applicable)
• ARP Main Studs (We check for out of round and line hone if necessary)
• Forged I Beam Connecting Rods
• Forged HD Series Pistons

Options

• Crankshaft: We use standard size OEM crankshafts most frequently as we have not had a crankshaft failure to date. However, we realize that cores are hard to come by and there are weight advantages with some aftermarket crankshafts so we will happily build your shortblock accordingly!
• Oil Pump / Balance Shaft Elimination: Have us install a brand new OEM front case / oil pump assembly and balance shaft elimination kit for just $500 additional.
• Rods: Please note that Manley rods require extra labor for clearancing and therefore add an additional cost.

Core Exchange Program

If you want to expedite the process we do have a core exchange program available in which we will use our block and crank to get started. If you would like to take advantage of this program there is a core charge which will be refunded when we receive your original block and crank and verify they are in good, usable condition. You can also simply purchase the block and crank from us for this amount by simply adding the core exchange program to your purchase without the intent of sending in a core replacement.

We won't settle for anything less than the best when it comes to our engine builds. We utilize quality components along with specialized machining and assembly techniques for each individual platform to ensure the best possible performance. If we see a gap in regards to acceptable product offerings on the market we often times develop our own like the Ultimate Duty Connecting Rods. We thoroughly inspect, blueprint, clean and assemble our engines in a clean room and most of the machine work is performed in house to satisfy our stringent requirements. We have had great success in building countless motors for every imaginable application from the weekend warrior to the all out race car.
