Honda 1.8L B18C Shortblock by MAPerformance

Years of experience and hundreds of successful builds have given us a pretty good idea of what these motors like! If you plan on making over 300whp safely you need one of these!

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

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 block and crank. You can also simply purchase the block and crank from us for this amount by simply adding the core exchange program to your purchase and noting that you will not be sending in your own items.

H-Beam rods are sufficient for most applications. If you plan on making more than 650whp we highly recommend selecting the sleeved option as that includes I-Beam Connecting rods.

Our pricing assumes that you will be sending us your block and crank for this service. This means that we will wait for them to begin working on it! Please note that all core exchanges must be able to be reused in order to receive a refund on your core charge.
