I did searching and came up with both opninions postive and negative. Would a B20b bottom end w\ a b16 head, be a good idea? And if so would it be ok to use the B16 tranny, or would an ls tranny be better??

 

Use a tranny calc.

Think.

But yes, other then milage b16 tranny is pretty much your best bet.

 

i heard to get the best out of a b16 tranny ur motor has to be able to be reved pretty high.....i'm not 100% sure if thats true though...

???

Misconceptions about transmission gearing always puzzle me. Having longer gears is better for boost, B16 trannys suck for ls motors, etc.

A shorter tranny is a shorter tranny regardless of your engine situation.

 

will the b16 tranny even fit on the b20 block?

yes it fits fine just like all other b-series tranny's . and shorter gearing is always the way to go unless you have a big turbo. you will always accelerate faster with shorter gears. why do you think they make 4.9 finals for type r's which already have close gearing

 

so the tranny i should stick with is the stock b16 one, i was thinking about switching the 5th gear w\ an Ls one so it is longer(for DD purposes), is there any other fabrication work needed to my car, sence i already had a B in there would it jus pop in ?

 

B16 tranny will be nice, but maybe something will a little taller gears like a GSR tranny would work best. b20vtec.com also has some fun info for b20s etc

 

B16 all the way

 

yeah you need a b16 tranny..the ls tranny is horrible with the b16 powerband.

fixed

it bogs my arpox 200WHP lsvtec down.

LS tranny isn't good for going fast.

Hmm aren't those statements contradictory. My B16 tranny works great on my LS.

I would go with the shortest gearing you can tolerate to drive on the street. You may want to run a b16 1-4 gears, but retain the LS 5th for cruising speeds.

FYI: I drove a b20 w/ ys1 short-gears on the racetrack. It was very nice. Didn't drive it on the highway though.
