i have a 2005 4dr civic si... is it the same set up in the engine bay as the Dx, Lx, Ex????

DumbasSi

They Si has VTEC with about 10 more hp then the other models. It probably has more standard features then the other models.Sunroof, power windows. locks, etc, nicer wheels.

so if i was to buy stuff for the engine, i should buy stuff the si and not the others

ex and si are the same model

but ya 7th gens have the same setup in the engine bay, just that the si/ex have vtec

good on gas / reliable

Jay P

yup


but IMO don't bother with performance on the d17 engines

save your money for a k swap or boost or both

you might wanna work on the suspension instead of engine mods first...

a CAI will make you "feel" faster for the cheapest of the 3 things (i/h/e)

Just to clarify things, if you are looking at parts in the US, Si means our SiR EP hatch so, it would be parts for a K20.

Our Si (sedan or coupe) are EX in the US.

there are EX in canada too...

in canada, there is just 1 extra trim level than the US

canadian stealerships tries to rip people off a little more buy having an EX and Si in which Si has the sporty stuff... EX has some sort of extra stuff over the DX/LX, but not the sporty stuff from an Si...

but i think later on EX are no longer EX, they rather make it SE

my friend drives a 97 EX 4dr i also got a friend who drives a 99 SE, both are the same haha... exchange the minor changeover of headlights and tailights, and front bumper and the climate control

I am not sure if you read the original post properly but the guy was asking about a 2005 Civic. A 7th gen Civic. As far as I know, there was never an "EX" trim level on a 7th gen offered in Canada. There was for the 6th gen and there is for a 8th gen but not 7th.

Also, with the 6th gen coupe, there was a version called an EX in the US which was equivalent to our Si so, what JPWEND!! ([US] EX and [Canadian] Si are the same model) posted was technically correct. All US 6th and 7th gen EX had VTEC.

Also, the '97 EX (the equivalent in the US was LX) and '99 SE were not exactly the same (of course I am not including the change points that were made on all the 99/00 from 96-98). The EX had power window but the SE had the manual cranks. The SE had keyless entry standard but the EX (even 99/00) had that as an option. There were also some other minor differences...

Generally, the "SE" versions are optioned up LX models....with some differences to the EX models.

excellent point...

suspension/brakes first...performance after

1sykcoupe

dont cheap out on suspension / brakes either. wait till u have the money to do it or dont do it at all.

i agree on the suspension part but not sure about the brakes as you guys mentioned. with no significant mods to the engine's performance, OEM brakes are still good...the car is not going any faster for it to need a brake upgrade imo.
