Well at 7000 miles the poor tuning finally caught up with me. Cracked ringlands on all four pistons....but I've got some new ideas in mind now. Going to put an unmilled head on and run 10psi through a DSM T25 turbo. Probably an OBD-1 swap in the future too...stay tuned!


Destroyed ringland:



Piston to valve contact:

Been awhile since I've updated. Currently brainstorming out a D16Z6 turbo build with MrCooper from http://civic4g.com. It should turn out to be a pretty nice build, hope to update with photos and part info soon!

Honda D15B2 Specifications

The Honda D15B2 is one of the most common engines built by Honda. It came in the USDM 4th generation Civic DX hatchbacks, DX sedans, and LX sedans. Also came in the 2nd generation CRX DX's. It shares many similarities with the D15B1 and D15B7's also.

In stock form, it produces a meager 92hp. Great for fuel economy, but bad for performance. Surprisingly enough though, the engine can be built to perform quite well without the use of forced induction or nitrous. There are many options for this engine, everything from upgraded OEM parts to aftermarket parts.
