Sport vs "base" 1.5T?

[zx2down]

Has anyone found out what exactly the difference is?
I see people saying that the two have different engine codes. Based on that it seems that the difference should be more than just a bit of ECU tuning as that would have no reason to be a different engine part number.

I believe the only mechanical difference is the exhaust and the necessary modifications to accommodate it. That's where the slight power boost comes from.

Otherwise it's all aesthetics/trim differences.

Unless the header is different I'm not sure why that would still be a different engine code.

Shouldn't be any difference motor wise besides the exhaust. Other than that it's wheels and a lot of body stuff.

Transmission and Longblock have the same part numbers between the two model trims. I would imagine it is just software, CVT paddle shifters, and exhaust that is different. Mechanically, it looks the same.

CVT transmission also says P, R, N , D, S on sport, where other CVTs have P, R, D, S, L

and a pair of paddle shifters~~~

Springs (and maybe sways) are also different. I think the Sport trims ride a half-inch lower, and am pretty sure the springs are stiffer, although I haven't seen any spring rate numbers yet.

Just to clarify, I'm talking about the engine only. I saw it mentioned they are different engine codes, but if they are identical engines there would be no need for 2 codes.

Well for the hatch I know the suspension is tuned differently paddles exhaust and the steering ratio also make it different those were a big reason why I chose the hatch sport . Along with the wheels I believe helped even more power shouldn't be a difference am wondering if the tune for the hatch is differently cause the car drives amazingly on 93 they should dyno all three to see if there are any differences in dyno sheets and the way they make power. Cause when I drove a civic EX-l coupe I did not get the excitement of when I drove the hatch. Also wondering why hatch has N instead of L.

Probably just because the Sport engines are done in the UK and sold in different markets. Honda has always had some varying engine codes for different markets despite engines being virtually identical or even complete different. An example of this is the K20A3 and the K20A4/K20A6...virtually identical motors but different engine codes in different markets in different cars. Maybe has something to do with the type of fuel that the engine is able to utilize? Who knows...

Honda has also done some wonky stuff, for instance the K20A is a code that's used for 2 completely different engines, one that has ~210-220hp and another that has 160hp (in fact I think it's the same engine as the K20A3 in the base RSX).

Wouldn't put a whole lot of thought into figuring out the nuances (if any).

Thanks for the lesson, seem to me they would do that. Would suck wanting to buy a 220Hp engine and ending up with a 160Hp version.

Yeah I remember when I was contemplating an engine swap in my EP3, looking at K20A engines.

It's pretty clear which engines are from the Type R (red valve cover, aluminum IM and price); but I could see if someone didn't know a whole lot could get bamboozled by the lower price on the lesser K20A (JDM base RSX).

It was all about the letters and numbers after the K20 as each one was a different code. You had A A1 A2 A3 A4 A6 C1 in the new type-r C2 in the current base models Z1 Z2 Z3 and Z4. That's a lot of different codes for different cars and output variations of the K20.

If you're really interested, here's the info on the 1.5. https://en.wikipedia.org/wiki/Honda_L_engine#L15B7

Mine isn't listed. I have a L15BA (182hp)

I'm guessing it is still incomplete as it is wikipedia.
