IMO your high gears are gonna put a strain on the motor in the long run. what are you lookin to do with this set up? racing or DD? LSV? need more info but the ls is a low revving motor and the b16 trans is a high revving tranny.

Sell the Si and get a GSR tranny. 5th gear is sorta low, but I was still able to get almost 48mpg on the interstate and I get about 37 city, with having a little fun. Get a quiet exhaust and you'll be good. You do about 3000rpms at 70mph.

shortest gears in any b series tranny. good for racing not for daliy.
if you put a ls 5th in the b16 it will do really good, and still have those short gears you want.
my buddy has one on his ls, and it sucks, i wouldnt reccomend it.

37city!?!? the fing crazy, i think i bearly get that on the highway!

WHat if I built The b18 to rev higher? Wouldn't I just need lighter valves and valve springs?

its the valvetrain. But it wont just let you rev as high as you want. But you can get like 1k more out of it at least.

^^ not only that. the rotating assembly is also the problem.
ls nor b20s were ment to rev 7000+
i have seen a ls spray its guts all the street due to the fact he turned a stock ls at 7900rpm.

^^why?? inless you bulid it your not going to gain anything.
ls is not a high reving motor, and makes almost no power in the high rpm range like the vtec b series engine that were desgined to rev over 7k rpms.
your wasting your money inless your going ls vtec.

B18 or B20=recipe for disaster with higher revs. get higher revs by grabbing a set of aftermarket rods

You're matching a gear set to an engine that is entirely mis-matched. The LS is a longer stroke, lower revving engine which makes more torque down low and less power up top; therefore, it has a longer geared transmission.

The B16 on the other hand is a shorter stroke, torqueless, high-revver. It is matched to higher gearing in order to utilize its revs and mask its lack of torque. Putting the B16 transmission on the LS is going to give a snappy low end yet fall off in the upper RPMs. Highway driving is going to yield more stress and less gas mileage as well...

because a built motor is a whole different game. It would have to be fully blueprinted weighted and balanced.
