i have a teg Ls i want more power and i was thinkin of a gsr swap too much $$ i was looking into the crv b20 and i hear it will be a cheap clean swap is it a worth wile proformance gain plus i still wont have v tech i need some advice

 

if you want more performance stick with the ls block and throw a vtec head on it

b20 swaps are cheap and make more torque, but the same amount of horse power as an LS, but the 1 piece iron sleeves are weak

if you take the money you have for the swap and invest in an lsvtec kit, vtec head of your choice and some arp rod bolts you wont regret it

 

yup what he said^ get a gsr ecu, GE LS-vtec kit off ebay and a stock vtec head and throw it on ur stock ls block and your set. all u need is arp rod bolts....the whole thing should only cost about about 600-800$ and u can finish it in about 2 days. youll be making about 180 bhp. i did it to mine and iv got 5,000 miles on it....still runnnin mad strong. good luck. BTW a b20 swap will only cost about 800$ but remeber its only makin 149bhp.

 

I have a B20b4 swap in my 95 se. I like the power I am getting and I plan on making it crvtec soon. I torque is nice though.

 

yea LS and B20 not all that much different. like every1 else says, get a VTEC head.. maybe down tha road throw some pistons and a different tranny in there too

 

Ok i dont know about everyone else on here who posted before me. but i actually own and use a b20 engine... infact i have two integras each with a b20.

it is a great replacement to the LS engine.
people say that they make around the same amount of horsepower at the crank

and they make almost the same amount of lbs in torque..... but you know what the difference is? all the b20s power kicks in a hell of a lot sooner than the b18bs power does....
and i mean a lot sooner.

i had a b18b with exhaust AEM intake, and dc port 4-1 headers.....(keep in mind that engine had 200k miles though) and when i replaced it with the b20 the b20 actually felt more powerful than that ls engine did..... and thats without the mods!

also the horsepower ratings people get for the b20b are with the b20bs intake manifold which is in no way a good flowing manifold for performance... when you swap it in you have to use an LS manifold which is one of the best flowing integra manifolds made. or you can use a skunk2 or skunk2 replica in which case youll make even more power.....

anyways down to the point

the b20 does make a good amount of power more than your ls engine does....

have you ever been driving in your car(back when it was stock) and as soon as someone heavy sits in the car with you, you can feel it when you drive cause you have to give it more gas?? well not with the b20.

the only downside is if you wanna turbo in the future.... because the walls of the b20 are kind of thin.... but as long as you replace the rods and pistons of your engine so you have a better rod ratio and you run relatively low psi with a good tune you should be more than ok.
