After 183K on my TSX, the engine needs replaced or rebuilt. I wanted to see if anyone has experience and can offer some sound opinions on the four options I've posted on this thread. I'm having it checked out this weekend so I should know more whether the problem lies in the short block or the cylinder head. My four options are to (1) rebuild the motor depending on the issues and cost, (2) purchase a low-mileage replacement motor, (3) consider an engine swap from the current K24A2 to the JDM K20A Euro R/Type R motor, or (4) sell the car as is and get something else to drive as my daily driver. I have another car but it's a weekend/track toy (2008 S2000 CR). I'm leaning towards rebuilding engine and making slight performance improvements with upgraded parts (e.g. high performance parts) or possible combining the K24A2 with the K20A2 cylinder head (from RSX Type S) for the ultimate K-series engine. I'm a bit reluctant to move away from the short block of the K24A2 that I currently have as 2006-2007years have the stronger crankshaft and reinforced rod bearings in comparison to the later model TSX's which I believe use the K24A4 (Accord) short block components. So the short block I have is the best offering in the K-series. The improvements can be made in the top end of the motor and still keep the integrity of the TSX K24A2 motor (also hate to lose the torque but really want the high revving K20A at 8,000 RPM).

Expert opinions or engine building experiences anyone?

 

 

What actually failed on the engine?
As a DD, unless you want it to be a project car, I'd swap for a new engine or get a new vehicle. Hard to be a DD if it's broken.

 

If you have a 6 speed....I would toy with it. Meaning create the K20/K24 motor and swap the gears to the SI with LSD.

 

I've done a replacement motor on another car once. The problem is: how long has that motor been sitting around? Even a relatively new one can get gasket issues by not being conditioned from running oil.

Unless the car is a classic or low miles on the transmission/suspension, it's worth it to me to get a car with less miles on those 2 areas.

 

183 K on the block? I'd be careful about fitting a new head onto a high mileage block. I tried that with an old Z car and blew the rings right out of it. (90 MPH around a highway bend, motor seizes up and rear wheels lock. 1/4 mile skid mark across the highway. LOL) New head= higher compression, Higher compression does not make for good news for old block. just My.02
