91 civic si

[Stacygifford]

OK, some of you guys may have seen my other car thread "The Joker"
Within the next week and 1/2 or so I will be buying a 1991 Honda civic si hatchback! While I know it is not the most fuel efficient vehicle, I came across it for less than $1000....

My dad's friend owns a wrecking yard and it was repossessed. So that's a big win for me!

I know a lot about the D series Honda engines, however I don't know much about the B series engines, other than they make a "lot" of power , at least compared to the other options Honda has.

This car does have a b-series in it, by looking at the picture he sent me, can any of you tell which engine it is?

It could be a B18B (integra ls) as it does not have VTEC. But because it looks like factory engine mounts and not moved from original location I bet it is one of the ZC motors from the D series (early integra).

There looks to be a sticker of some kind on the boss where the engine type stamp lives. Take another pic, just to the left of the exhaust manifold, further down. There's a flat boss on the engine case that should have a stamped engine type on it.

It's definitely a swap; the US-spec 91 Si came with the D16A6 motor originally, which is SOHC.

That's a dohc ls swap you could do a drop out and sell it for the car price most likely.

It was a Canadian car

I know it looks just like the b18 in the 96 integra
And if I'm not mistaken the zc valve covers don't have the horazontal lines on them

Ah, the DOHC ZC appears to have raised areas fore-and-aft across its valve cover!



So yeah, I'm betting a B18. Possibly a B16? A look at the boss on the front side of the motor would tell.

I am glad to know its not the zc... if it is the b 18 I plan on installing some adjustable can gears, chip the ecu and see how much mileage I can squeek out of this thing! The car is in elpaso.. if I get it I will be going down there next weekend! Hopefully

not the B16 or B18C. Those have VTEC cast onto the valve cover and a cover over the spark plugs. It does look like a B block. I'm just surprised the mounts look original. I thought B blocks needed to custom mounts in that generation. Also looks to small to be the larger B20 or F blocks.

Probably a B18B from the 96+ Integra LS.

Sorry, it took so long to get back on here! but i got the car for $1000! here it is.

I drove it home from Elpaso to Lubbock and got 27 mpg the first half of the trip. 31 the second half. (75-85mph then 50-65) It does have some issues... third gear is COMPLEEATLY gone... trans rebuild kit is $275. might slap in a higher final drive gear in it while Im in it.
It has a Hondata ecu
Skunk2 Pro intake manifold (factory throttle body)
4-2-1 header (should help low end torque)
It is a B18B1

HELP!!! I don't know what trans it has!!! the I.D. sticker is gone i know it is a cable trans. a y80 or s80 come factory on a b18b1, but there hydro... the YS1 is cable... but I am lost.
