Evo X Shortblocks
"Since I didn't have 5th and 6th gear, I was forced to use 3rd and 4th the entire race. Which forced me to constantly bounce it off the Rev limiter at nearly 9,000-9,500 rpms for 5-8 seconds... 3 times a lap. Now I know that MAPerformance has a great rep with building Evo X blocks, but I thought for sure the insane abuse I put on the motor it was going to blow for sure. I was absolutely dumbfounded that it didn't even so much as show 1 count of knock the entire two days of beating the ever living shit out of it. If you would have heard me driving you'd swear I was actually TRYING to blow the motor! Huge Props to Darton, MAPerformance and BC for the kick ass motor !" -- Jeremy Rohrs, South Side Performance on EvoXForums.com

Included Services
- Engine blocks visit our hot tank before and after machining for a clean, 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 a three step honing process utilizing a 4B11T specific torque plate to ensure roundness. Our three step honing process 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.
Core Exchange Program
Our stage 1 shortblocks do not feature an overbore as the stock sleeves get too thin for our liking at .020" over. As such, we require that your core be in pristine condition so that any defects or blemishes in the cylinder wall can be removed in our honing process. If your core is not acceptable we can either build from a new OEM shortblock or build you a stage 2 shortblock that features aftermarket sleeves.
*Please note that all core exchanges must be able to be reused in order to receive a refund on your core charge.
Shipping
Please note that this item does not qualify for free shipping. Shipping methods and charges will be determined when the service is completed and can range from $200-$300.Stage 2 - Rated to 800+whp
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 650whp you need one of these!
Disclaimer
MAP recommends a maximum bore size of 89mm. The 1mm difference in the cylinder bore results in a mere .05L displacement differential, but allows for a future overbore to 89.5mm or 90mm potentially saving thousands of dollars should a failure occur for whatever reason.
2.0L Features & Benefits
