I have a 2004 TSX with a blown motor. It also has parts missing. I can get a 2006 engine. I am looking for Information to see if everything will work\fit so I can do this. Wiring, ECU, everything. Any information would be appreaciated.

Are you the original owner of the car? If not, how long have you had it? How did the engine blow?

No, I just bought the car. The Motor was worked on by an idot who caused all of the problems, which inturn did all of the damage to the motor.
Repairing the present engine, is not an option because I don't know what's there and what isn't.
I can get this 2006 motor which only has 66,000 miles on it, ifit will work.

I am not sure and don't quote me on this but i believe there are very minor differences between the 2004 and 2006 engine. The 2006 only produced about 5 to 15 extra horsepower. But the outside dimensions are probably the same. You need to confirm this with a knowledgeable party. Good luck.

Boulder TSX

The 2006+ engine produced 13 extra HP over the 04-05...due to a number of changes, none of them adding any extra dimension or size to the engine. Sounds like you might need the larger diameter exhaust tubing, as well, But I don't see why it wouldn't work.

From Road & Track magazine:

Breathing changes for the car's 2.4-liter i-VTEC inline-4 are numerous. On the good-air side, bigger-diameter tubes in the intake ducting and a larger throttle body (from 60 mm to 64) are good for a 15-percent flow improvement alone. The high-rpm intake cam lobes are ground with more lift and duration, coupled with an increase in intake valve size (from 35 mm to 36).

Spent gases exit more easily too, thanks to a larger header downpipe, a high-flow catalytic converter and slightly upsized tubing aft of that. Even airflow beneath the pistons is optimized-the block is drilled longitudinally just below the cylinder bores to reduce cylinder-to-cylinder pumping pressures.

These changes make for an especially strong-running engine, at least at high revs...205 bhp at 7000 rpm, and 164 lb.-ft. of torque at 4500. Compare this with last year's TSX (200 bhp/6800 rpm; 166 lb.-ft./4500 rpm) and you'd have every right to say, "So what?" Yet 2006's ratings are obtained using the new SAE J1349 standard (see Tech Tidbits, November 2005) that yields somewhat lower numbers. In an apples-to-apples comparison, Acura people tell us, the new powerplant is about 13 bhp stronger.

04-05 Diagnositics and Troubleshooting is different than 06...this uimplies computer and other changes. I doubt the swap is worth the trouble...the wiring harness is different too.
