I was asking for a opinion
Alright then: it sucks balls. It's a fine motor, but in an Integra it's like using the very best cordless power drill to dig for oil... it ain't gonna be quick.
Why? Well, why would you swap an 1834cc engine for a 1595cc one? Sure you'll be getting 20hp more due to the wondrous "VEE-TAK," but you'll be getting 13lb/ft less and that's... less... I'd rather have a big motor with lots of leftover potential, N/A/turbo/other, than a small motor that's already making 100hp/L. HP is simply torque*rpm/5252... it's a lot easier to make an N/A engine breathe better at high rpm than to create torque.
You currently have 124lb/ft @ 5200rpm according to factory specs, while a B16A has 111lb/ft way up at 7000rpm. Translation: peaky as hell, and nothing happens til you get there. I love watching B16 Si's and Integras autocross, because every straightaway is like, "bbbbrrrrrrrrrmmmmmmmmm-BRAAP!! *brake* *corner*"... they are teeth-gratingly slow until their half-second of VTEC glory, then hard on the brakes... it's genuinely painful (yet amusing) to watch. Doesn't sound like the hot-rod swap we all want.
Even in the 1/4 mile, where you should be in the magic VTEC range all the time, the B16 Civic Si (which believe it or not weighs the same as an LS) runs mid-high 15s... hardly any faster than an LS to begin with, and you'll be lagging hard below VTEC range. Mind you this is WITH the B16's WWWAAAAYYY shorter-geared tranny. Put that tranny on an LS and you'd probably get just about the same time. I should know, I've done it.
Sirfallsalot243 as you can see priced a B16 swap out at about $2200. Funny, since I've spent exactly that much on my all-motor LS setup including dyno time, a setup that the majority of the great unwashed in the "import scene" would say is worthless. What did I get for the same price? Well, more torque
at the wheels at 2800rpm than a B16 has
at the flywheel at its 7000rpm peak for one thing. Plus a solid +15whp up top, about
40+lb/ft more at a nearly 3000rpm lower peak and a far broader powerband, all while running 87 octane. No it's not the fastest setup in the world. But that's not what I was going for, and I'd rather have this than spend the same money on a gutless, 1/4-liter-smaller swap. Something that's not already close to tapped out, and that can only get out of its own way if it's above 5500rpm.
So there's the opinion you asked for, even though I've said it at least a half-dozen times here before. SHO's search function finds a way to hide things sometimes.
