Hi all,

I was hoping that someone would know about the Stock engines that were put into the 98 and 99 Civic Coupe SI. I am in Canada so i assume that model corresponds to the canadian version. I was hoping that one of them has VTEC and DOHC technology.

Thanks for all the replies!

I think the 6th Gen Canadian Si equals the US EX. The Canadian SiR equals the US Si. The EX came with a VTEC SOHC and the Si with a VTEC DOHC.

what you want to exactly know?

US civic ex came with d16 127hp sohc with vtec-E (Si canadian)

US civic SI came with b16a2 160hp DOHC with performance vtec (canadian sir)

will the si motor drop into the ex. Yes. You can also drop in a integra gsr motor b18c1 with 170hp DOHC.

Thanks for all the replies. I believe it answered my question. I'm just worried that that i'm not getting what i paid for. Although i prefer to have DOHC engine but it's hard to find.

so the major upgrade from d16 & b16 is DOHC, 35+hp, and low end Torque right?? What about the redline issues, brakes, suspension as to how much i can push my car without many upgrades.(hopefully keeping it as much as possible Stock for now)

The sir comes with better suspension and brakes. There is a huge difference between the B and D series engines. If you can try to get a B series engine. A used USDM civic si goes for $4500-6000 US now. Its worth it pay the extra money for the SIR.

redline on the b16 is 8200rpm and i think the d16 is around 6800rpm.

...so u can basicly drop the b16 into the ex....with no problems?

its pretty straight forward. I believe you just need to buy b-series mounts. A experienced honda tuner can finish the swap in about a day. Just do a search on Honda-tech.com for more details.
