What is the difference between Honda Accord and Acura TSX 4 cylinder engines?
A friend of mine recently bought a 2004 Honda Accord coupe with the 4 cylinder engine. I was very surprised that the Honda Accord now has a Dual Overhead Cam. It said 2.4 DOHC on the engine cover.
Is this the first time that Honda Accords sold in this country have DOHC?. I thought it was just reserved for the Acuras that were sold in this country.
Also, it seems that both engines are 2.4 liter engines. How does the TSX engine generate the extra 40 horsepower?
I would think that additional 40 horsepower makes very little difference in acceleration from a dead stop (at least initially). At highway speeds is where I would think it makes a difference. Am I wrong on this?
I will be getting a car this year. I am constantly switching between the two. I would get the Accord if it wasn't for that Hideous instrument cluster with that Huge speedometer. It looks so cheap. The TSX instrument panel is so much nicer.
Thanks for any responses.

I'm doing an educated guess here:
1) Higher compression (I'm not sure about this)
2) Advanced timing (thus requires premium)
3) Different intake and exhaust
4) Tuned for premium gas, etc.
5) Higher RPM redline.
EDIT:
Extra facts
Accord, TSX
1) Compression = 9.7 vs. 10.5
2) Mileage = 26/34 vs. 21/29
So overall, I'd say the TSX is dumping more fuel into the engine with better airflow and exhaust.
