ls/vtec over b20/vtec??? no way

 

b20 has a84mm bore to where b18b does not , also the sleeves on the b20 are stronger

Um, no they are not.

 

b18b loves boost

 

i just swapped a b20 in my ek...i love the torque and am very pleased. 14.6 with 1 mount missing and 1 broken. i would go with b20 for sure

Actually, the sleeves in the B20 motor are weak. They break all the time when you high rev them. Get a good reputable company to sleeve the B20 block, port & polish, and you'll have a strong/reliable motor.

 

Are you going to boost it? If you are eventually going to turbo this new motor I would definately go with the b18b. Those motors make incredible numbers when turboed. The b20 is a better for all motor and boosting it would make me uneasy with the weak sleeves that were mentioned earlier.

actually my friend made 40lbs more torque when he swapped his b18 for a b20, so my b20 vote still stands

EDIT: this was for a turbo app

no way!!

B20 block with ITR head willl make much more power than ITR motor

 

Depends on what your plans are for the motor,
B20 is what I'm going with 6-7psi boost.
But an LS can hold up aa lot longer and lot more amounts of boost.Just check the FI forum.Good Luck.

 

my stock b20 ek woops on my friend's LS swapped ek every single time, you want torque...go for the b20!

 

If I was you I would go B18B w/Gsr head. B20 are good but they wieght a lot.

 

or straight LS sleeved, new rods and pistons like me....a dash of hondata to tune the biatch and some beefed up valvetrain. GE is sleeving my block for $850, i thought it would cost more.

So you are confirming that a b20 makes more power all motor like I said?

where do people get their info from hahaha

 

i lifted each one in turn and they both felt the same. but it was the b20 that broke my scale. I think it was the extra 5 lbs from the beefier valve cover. ahaha

d

 

all a b20 is a bored out b18b1. it has more displacement thus is better for all motor. if your turboing then the b18b1 is better.

first off your an idiot for makeing such a bold statement. Have you even done any reaserch in the b20? probably not, seening as how in stock for they suck *** when modifiing. there cyl walls can't handle high compression (most of the time anything above 11.8, will result you in with a cracked sleeve). also the compression ratio on that motor is soo low you expect to make 'made power' buy throwing an itr head on that which normally sees a full 1.5-2 points high in compression.

now im not saying that b20's are not a good motor but you just can't do much to them in stock forum. personally in stock forum the b18b has TONS more potential. with out haveing to modifi it. now if you want to the vtec route ill sggest you get a gsr motor and work from there. but i don't think you want to go that route, personally i wouldn't do the LS/vtec or crvtec, as i see them both being no more then shitty base for VTEC. if you want vtec get a gsr bore it out alil through some nice High compression pistons in there build the head and you will have something just as good with better reliablity then ls/vtec or crvtec. now im gona set back and watch all these guys say "ls/vtec" makes more power bla bla bla bla bla. ya whatever NO IT DOESN"T
