sorry if you guys have already cover this topic but somehow i searched everywhere and nothing came up for me.. i was wondering which tranny would be better for me to get on my B20V if i wanted to get good time at track and still do good on highway/topend races.. please help bc i am almost done with my build and need to figure which tranny to get

 

bump.. gsr or si tranny for b20v???

 

because of the torque the Si would be a very good candidate on this one if you are going to be racing it quite often.. but the highway is always going to have the rpms up.. the Gsr is a great transmission for all around.. it's good to run on the highway plus you can still run good times... I would go with the Gsr tranny just because you are wanting a good Highway tranny too..

 

anymore suggestion?? if not im going with this brothers idea of gsr tranny being more versatile.

 

I would go Gsr over Si(sir here in canada). Had the si tranny to built ls and was a pain on the highway, unless you get a ls 5th gear in your si tranny.

 

im not worried about getting good gas mileage on highway.. im looking for power on highway lol.. i dont want to go 110mph and be on 5th gear already while everyone else is still on 4th and creeping pass me bc thier 4th gear is still going and making power.. MAYBE change ls/gsr 4th and 5th gear into b16??

 

Then get the Si. Or even better the Type R with OEM LSD. The Type R has the same gear ratio as the Si.

DON'T EVER put a GSR 4th. I did that mistake with my Type R transmission on my B18C5. I switched back to the Type R/Si 4th and gained .1 on 1/4 mile.

I got a RS 5th.

If you're looking for top speed and are not affraid about gas milleage I suggest you to get the GSR 5th. The Si might be too short, the RS is too long, you'll have an incredibly high top speed, but no acceleration.

 

Get a c5 LSD tranny if you have the extra money,best all around.

 

You can't swap just 4th gear out.. the JDM Type R tranny comes with LSD and a 4.78 final drive and the gears if you have the cash this is the way to go .. the Si and Type R will both end up being really short and you'll run like 130 topped out, but you'll get there really quickly.. If you are considering building a tranny, then I would say Si 1st-2nd, Gsr 3rd-4th, and LS 5th

 

ok this sounds reasonable and seems to fit what i want xD.. thx ALL for your opinions

 

i think ppl exaggerate the b16 tranny on the highway... at cruisin yes its higher rpm's but it just gets my car moving quicker on the highway. ive taken my b16 tranny past 145 mph so its not a top out issue. ide go b16 especially if ur doing alot of track runs. ive recently put a type r 4.7 final in it and love it even more.

 

My buddy had a complete b16 swap running a p30 in his hatch and topped out at like 126 mph.. I have a b16 with a Gsr tranny behind it.. but i'm not saying it's a bad tranny to put in it, I mean it'll probably be one of the best ones, I was just stating the Gsr or so because of cruising at 80mph the rpms would be at around 4.5-5k rpms... 00b20vtecoupe.. that is a very nice coupe in ur avatar man.. nice job on that one..

 

im running a b20 with a b16 transmission with an lsd installed... it's great in the city but it eats gas on the highway... no complaints though... if it wasn't for the lsd i would have prefered a gsr transmission

 

I run a B20 with a B16 tranny.... it is a blast but sometimes i wish I has a GSR

 

from best to worst I would pick

1)the 98 itr tranny with ls 5th
2)the lsd b16 tranny with ls 5th
3)the gsr lsd tranny stock
4)the b16 non lsd with ls 5th
5)the gsr non lsd tranny stock
6)the b16 non lsd tranny stock
