Good Afternoon....

I hope this thread doesnt get flamed, but here goes.....

Id like to know the differences between an SI and an EX (1999)
Ive done a few straggled searches however there results varied...

Interiror aesthetic differences I can notice so far, like seats.....but what else?

And the head looks different as well....is the Block the same?...Please and thanks for your responses!

thanks
Mike.

no they are not the same. the si has a b16 motor dual cam vtec. the ex has a d16y8 single cam vtec. BIG differance.

yep! the motor is a hella big difference! DOHC motor

exterior: the front grill is mesh on a si rather than the standard honda grill, the side skirts are painted to match the car on an si, there is a front lip on an si, and there is a crome exhaust tip on the stock si muffler.

interior: the seats are different, the gauge cluster, clock, and all controls light up amber (I think) and I'm sure there are a few things I'm missing interior wise... I dunno? I hope this helps you out a little!

Hook a cracka up w/ some rep points!!! cya...

I better get some rep points for this...

comparison of 99/00 ex to 99/00 si

*The si has a stock front lip the ex does not

*The si does not have stock oem fogs (but they do look really good)

*The si has a black mesh grill the ex has a grill that looks more like this ==H==

*The motor(biggest difference) the head and block are both very different.
EX=D16y8 single overhead cam (with vtec) rated from honda at 127 hp.redline at 6800
SI=B16 dual overhead cam (with vtec) rated from honda at 160 hp.redline at 7400

*The sideskirts come painted body color on si, ex skirts come flat black

*The si comes with alloy wheels, the ex comes with hubbies!

*The si has an si amber lit cluster, ex lights are a greenish color

*The si only comes in 5 speed manual, ex available in automatic as well

*The si has a slightly different suspension from the ex

*The si has rear disc brakes, the ex has brake drums in back.

*The si headrests have a box hole in them, the ex ones are flat across.

*The si for those years had an exclusive color (not in ex,lx,dx,hx) electron blue pearl

*Badges different of course

*The actual design on the seats is different on the si

[B]There are probably other things but thats all I can think of right now. I know these becuase I got an auto ex and I could have gotten a si. I think about all those differences every day.

the SI motor is not only faster stock, it has ALOT more potential, its the B16, do a search

neksone

thanks....So I should look for a b16 swap as opposed to an "si motor"?
