tegboy Posted March 26, 2002 Share Posted March 26, 2002 OK IM THINKIN ABOUT PUTTING A B-20 HEAD ON MY LS. I HAVE HEARD GOOD AND BAD THINGS ABOUT DOING THIS. IT SEEMS SORTA WEIRD SINCE IT IS OUT OF A CRV AND ALL BUT IT DOES HAVE BIGGER VALVES BUT I HEARD EVEN WITH THE BIGGER VALVES THAT THE B-18 WILL FLOW BETTER AND THAT THE B-20 IS A BIT MORE SLUGGISH. I HAVE EHARD OF A FEW PEOPLE DOING THIS AND IVE ALSO HEARD OF PEOPLE PUTTING THE WHOLE FREAKING ENGINE IN OR JUST THE BLOCK...BASCIALLY ANYTHING...BUT ANYWAY...IF ANYONE KNOWS ANYTHING ABOUT THIS TOPIC PLEASE SHARE YOUR KNOWLEDGE. THANKS A LOT. Link to comment Share on other sites More sharing options...
Trepid Posted March 26, 2002 Share Posted March 26, 2002 I don't know too much about the topic but I have heard that the B20 is a faster engine but it makes the car really heavy... you would need a turbo or something to get it over the lower rpms. I'm a civic man myself so don't take what I say to be the word Link to comment Share on other sites More sharing options...
Barbed_Elf3000 Posted April 25, 2002 Share Posted April 25, 2002 screw the b 20 spend the money on a gsr engine, as the other guy said the b20 is very heavy yo put in a tiny car like a integra Link to comment Share on other sites More sharing options...
theoverachiever Posted April 28, 2002 Share Posted April 28, 2002 First off, i drive a GSR and even with 4/2/1 headers, it has no bottom end...but wait till 5500 rpm and it will sing all the way up to its 8000 rpm redline. If you are more into bottom end i would recomend an ls/vtec aka frankenstein engine. It would be more reliable than a CRV-vtec as for the b20 was not built to handle vtec.-not that the ls was but from my experience it is a much more solid engine. With regards to weight, i doubt that the extra .2 liters will weigh the car down that much, and to tell you the truth, the "civic man" probably has no idea what the hell he is talking about...a b20 vtec will give you gobs of torque...more than a front drive car would ever need. as for his remark about "needing a turbo or something" any bonehead should know that a turbo doesnt spool up until higher rpms anyway so it wont do much to "get you over the lower rpms". Since you have an ls right now, i would recomend getting a drag turbo kit, for it will let you keep both the low end torque of an LS as well as plenty of top end. Also your ls has taller gearing than a GSR which would make it a great freeway racer if equiped with turbo. BTW, on your post you were asking about a "b-20 head on an ls"...i hope you intended to say b20 bottom end cause the head certainly wont do you any good. If you want to go to a real forum with people who actually know what they are talking about, i would recomend www.honda-acura.net Link to comment Share on other sites More sharing options...

I just got the B20Z swap in my 91 integra. Not to shabbie. But I need the high end. I might get the b16 head, and new pistons. what do ya think.

I might get the b16 head, and new pistons. what do ya think. ive heard both ways as far as the b20vtec goes. The other day i actually went down to WMR to get a b20/vtec put in my gsr --im 16y/o and my dad would have a fit if he saw an intercooler on the front of my car but when i got down there the guy talked me out of it. as far as power goes, you canot beat the crvvtec but if reliability is a major concern, ive heard that the crv engine cannot handle some aspect of vtec and for some reason that causes the engine to blow up...your call but the idea sounded real tempting when i first heard of it. Currently i have i/e/h/cat and ive pretty much run against a wall as far as cost v performance goes(turbo is not an option). If you have any ideas please let me know-im considering a stroker kit but im not sure where to get them and how much it will cost. Link to comment Share on other sites More sharing options...

You mention a "drag turbo Kit" in your message and I was wondering if you could help me by explaining what exactly this is. I am not really a die hard car person and have only begun to regain an interest in cars because a lot of my friends from school are now into it, and that is pretty much all they talk about. Everyday they are discussing terms or codes for different engines, and I am left clueless as to what they are saying. My friends are so into the integras and civics that they can tell the difference between different cars, just by looking at the side moldings or the wheel lugs. These guys are so in love with their Japanese imports that they once drove through a parking lot and tried to guess every single civic and integras model without looking at the emblems, and the scariest thing of all is that they got most of them right. Just the other day two of my friends were having a heated debate as to which model acura my friends shifter comes from, and my other friend was so convinced that the shifter came from an RSX that he bet ten dollars on it. The shifter however actually comes from a TL, and I am still left absolutely clueless as to how they know this. So if you can please help me out by describing what a drag turbo kit is, I will be able to hold a conversation with my friends, at least for a little while.

Maybe if you take a chill pill once in a while and not take your japanese imports so seriously then you might be able to pass the age of 20 without an ulcer!

You must be pretty well off to afford that kind of awesome machine! Nah, just joking. However maybe you should take more time to concentrate on more important things such as school and going to college because odds are, your grades are probably taking a beating with a GSR sitting in the driveway.

theachiever Posted May 8, 2002 Share Posted May 8, 2002 hi everyone. I myself a B20 in my civic w/ a gsr head. it super fast. I think the b20 w/ the gsr head is great...but i dont no wut the hell ur talking about putting a b20 head on an ls. thats dumb. Thats just putting a non v-tec head on bigger motor. a b20 head on and ls motor is pretty much te same thing as a nomal b20. Wut i think u should do is put a gsr head(that has v-tec) on ur b20(that has more displacement)in ur ls... otherwise just dont touch ur motor cuz ull break it.

TrueSi Posted May 12, 2002 Share Posted May 12, 2002 hey The underahiever a drag generation turbo kit is a kit thats almost a complete bolt on that includes turbo,interculer,bov,fittings, etc. as far as generations that only means the size of the turbo the bigger the generation is the more boost they can produce they also spoil much sooner. too bad a Drag Generaion III would run you about 3g's Link to comment Share on other sites More sharing options...
Suprafast Posted September 6, 2002 Share Posted September 6, 2002 A friend and I are doing a swap right now in a 2000 civic ex. We are putting a b18 with a t4 and a 50 shot in this week end. he had a sohc d16y7 but with the swap there are many problems as far as mounting goes.. anyway on to the subject. the guy that we get our engines from has a b20 block with a GSR b18 head. Needless to say that thing moves for a honda. He barks in 4th gear (all motor). So i would go with that.. Just my 2 cents... Link to comment Share on other sites More sharing options...
EGRacer Posted September 10, 2002 Share Posted September 10, 2002 go wit a b20 blcok and itr or ctr head. personally i go wit itr head. it will move liek mad fast Link to comment Share on other sites More sharing options...
Toda Party Posted September 13, 2002 Share Posted September 13, 2002 CTR and ITR head are the same thing Personally, i'd do the CTR head since the cams are a bit more aggressive. Link to comment Share on other sites More sharing options...
EGRacer Posted September 14, 2002 Share Posted September 14, 2002 yea but i mean not always. ive seen an itr and ctr dyno at way totally differnt hp and trq with the exact same mods Link to comment Share on other sites More sharing options...
Toda Party Posted September 15, 2002 Share Posted September 15, 2002 Obviously every single head is different. ITR and CTR are both PR3 casts. They have the same valvetrain, same t/b, intake manifold, and port/polish job. The difference is the cams. And that's why u see them dyno at different hp and tq numbers Link to comment Share on other sites More sharing options...
EGRacer Posted September 16, 2002 Share Posted September 16, 2002 tru thanks also for the extra info cause i wasnt really sure why they were so different but they littlest thing can change a whole motor Link to comment Share on other sites More sharing options...
