Default b18 lsvtec vs. b16

hey whats up guys, im new to this forum. my name is nic. Just got a general question, because i cant make up my mind. i have an eg hatch...and plan on going direct port nitrous...but i can't make up my mind on and engine. I was thinking either a b16 or lsvtec b18. Can you list all the plus's and minus's of each...i have a fair amount of general knowledge on both, but dont know alot of the technical stuff. thanks

B16
pros, you can throw right in and very reliable.
cons, not much torque.

ls/vtec
pros, a lot of torque and more power
cons, unreliable if not built correctly

If you build the ls/vtec the correct way, it will be reliable, but will probally end up costing more than a b16.

I'll add that if you have any type of forced induction on the ls/vtec--traction issues will occur if on the street w/ street tires.

B16's never have traction issues, which is a plus when coming outta the hole. Even under boost, 3rd,4th,and 5th gears are rock solid traction. (in most cases)
If you use the b16, I would make sure my gearing in the tranny was as short as my budget would allow, while using the LS 5th gear for cruising. B16's are good w/ higher revs, almost as good as any if you know how to stay up in the RPM's.

LS/Vtec is expensive to make reliable..but it will most likely be more fun, since the torque is usually a monster compared to the B16a and B18C.

lsvtec has to be build like a precision motor, or you will find yourself in alot of trouble. basicly the lsvtec is the b16 with more displacement equalling in more torque, but if you find yourself not that prepared onto getting the lsvtec built right, b16 might be your way

lsvtec is the way to go imo but you do have to build it correctly. it will make more tourqe than a b16. However b16's are easy to install fairly cheap to fix and they are reliable.

Never heard that. Any other threads with proff?

Also, I've been reading a lot abot the tech side of motor becuase I'm building a b20vtec setup. To start, the b16 is about as perfect as you can get for rpms. It has a 1.75 r/s ratio that allows it to rev all day without fail. Simply put, you can beat the crap out of them with no problems.

A b18b with some kind of vtec head on it isnt as reliable as say a GSR. This is also due to the r/s ratio. Its not quite as dramatic as it is in a b20, but it still is there. IM NOT saying that you can rev your b18b bottom to 8k. You can, infact people do it all the time without complications, its just HOW OFTEN you do it. A b18b doesnt have a block griddle, which also plays a part in the reliability factor.

Case and Point: A b16 is a great motor to beat on, but does not offer much power. LS/VTEC is a hard thing to do and take a lot of knowledge and experience to do the right way, not to mention money. If you arnt that experienced in motor work, i'd drop in a b16, and then go about studying engines. It'd be a real bummer to spend that much money on something and then have it blow up on you.

Go ahead and read that ENTIRE post. It'll help get your feet wet on the whole process.

Torque is what accelerates the car. I am pretty sure you will be happy with a ls vtec motor; the frankenstein motor is more than a decade old, it's nothing new. It has been built by many people and works great in drag and road course races. The reliable issue all comes to the person who knows what they are doing and builds the motor according to specs. And if rod stroke ratio discussion comes about, well if the rod ratio isn't so reliable how come honda built a 2.4l monster with a long stroke of 99mm with 1.54 ratio as the ls vtec then? Think about that.

Fair enough..I was really speaking about high boost applications and large sprays, something like 150 or bigger. I'm just saying that in high hp applications, the ls/vtec setups make way more torque than a b16, which at some point will hurt your traction some. I in no way mean to offend you guys, just telling the OP that the ls/vtec will be a totally different experience if done right, and his issues will not be the same as the B16. W/ the B16, his issue will be lack of torque, w/ the LS/Vtec, his issue could be traction.

If it's crazy for me to say that lots of torque will result in tirespin, then perhaps I will backtrack my previous post. Not trying to argue. After all, I did say that the LS/Vtec will be more fun either way, simply because it will have lots more torque, which will result in a faster car all else considered constant, like traction.

I'm not trying to post BS, I'm just stating that 300ft/lbs torque takes much more skill to utilize in a FWD than 200ft/lbs in a FWD. That's basically all I'm saying.
Here's a few posts regarding all that power you guys swear is undisputed. https://honda-tech.com/zerothread/1846195
Yes, more torque is better. Get the B16 and study up great amounts on the LS/Vtec setup, do your homework. Start building the LS/Vtec the right way, and don't hurry yourself, just take your time, using all of the good stuff. Then you will have a very good build, and if your engine builder is experienced, it should be reliable too.

but traction in 3rd 4th and 5th gear isnt great traction. short geared transmissions wont keep you in vtec and boost for longer periods of time like the ls transmissions would

the shorter gears will get you into the high mph however

longer gears will keep you in consisnat boost and vtec

not like boost shift boost shift like you do with the b16 tranny

just look at the nissans and supras all of their gears are longer for great period of boost to rpm powerband range

Maybe I'm reading wrong, or I'm completely retarded. A tranny such as the b16 tranny, or the gsr tranny is MEANT to keep you in vtec. Thats why they're orignally found on motors that came stock with vtec. The ls tranny is geared longer because it comes on a motor that wasnt really made for high performance applications, its geared to be an economy motor. make sense?

The ls trans is good for high boost application though, i wont argue with that. The gears in a b16 are much too short to be pounding a lot of hp through. you'll find yourself loosing traction, and like you said. however, with a n/a ls/vtec setup, you wont have to worry about that unless you do some serious engine work and tuning.
