On stand-by…

Eventually the new built block will go in. This along with Ferrea components up top, Boundary oil pump gear and PPG 1-4 gearset. Not trying to make huge power, reliable power is the overall aim. Been running the MHI drop-in turbo for about 3/4 of a year with no issues whatsoever. Would like to have it properly tuned by Derek once everything is in place, versus the MHI basemap included in HONDATA’s maps.

Cannot really review the block as it sits waiting, just glad to have it in my possession after about 4.5 months, no fault of TSP or CSS, cranks were just not readily available. Definitely looking forward to the more robust components.

Would definitely recommend for your big power goals

3k into the new motor and I'm loving it :)
I run a gtx2860r @34 psi with meth injection and I lost the stock motor in August. Twostepperformance was quick to help and get all my questions answered. At the end of the day I decided a built block was my best option. I intend to push this beast into the mid 400s for power, and the block shouldn't break a sweat.

Please note, there is currently a 8-10 week build time on orders that do not supply their own crankshaft upfront, but only a 6 week build time on orders that do supply their own crankshaft. Also, shipping costs are now included in the price of the shortblock assembly.

This package includes the following:

  • New bare block, crankshaft, and trigger wheel from Honda
  • Saenz or Brian Crower Rods
  • JE Forged Pistons (factory Si compression ratio is standard)
  • Cylinder Support System
  • Bore, Hone, Jetwash, Micropolish, and Assembly of Shortblock
  • Oil Squirter Blockoffs
  • Balance of the rotating assembly (Optional)

This shortblock is built for up to 600whp (see details below) but we expect it would hold much more. There have never been any reported failures.

Customization is available. You can save $800 by supplying your own bare block and crankshaft as a core. Alternate components can be used, if desired. Please contact us, if interested in a further customized build.

Due to aggressive pricing, discount codes may not be used on this product. TSP Reward codes are accepted.


GUARANTEE: If you crack a sleeve within 1yr at or under 600wHP we will reimburse the full price of the CSS process. 

1) Customer must provide us with the vehicles set-up, a dyno sheet and tuner info.

2) Guarantee does not cover cracked sleeves due to catastrophic failure (i.e. dropped valve, broken rod ect)
