I've read everywhere the ls tranny is low geared and to make it feel better going all motor you should swap it for a b16 or gsr tranny. I'll say it doesn't feel slow to me. I've driven an ex coupe civic and a crx both of which felt slower. Similar mods on all cars I'm just thinking of going for award with this tranny as it's just for me to enjoy no track time at all.

 

an LS trans has the LONGEST gearing of all b series. meaning the gears and Final drive have a higher top speed, but all-in all you have a slower acceleration. The reason the civic and CRX seem slower is because they are a D series motor, which have no power compared to a B series.

 

At most motor swap wise I'm thinking gsr or b20 but again I'm not going on a track. Is leaving the ls a bad idea given it will see a fair amount of highway time?

 

I don't see any type of question in your first post! If you do swap the engine go with the B20B, preferably a 99-00 year model. Reason being that it just feels better to drive, you can have fun driving the car and not have to completely thrash it like a B16A or B18C. I would suggest grabbing a GSR trans though, again for the same reason, being that the better gearing is more fun and it still revs low enough with freeway driving. Just my opinion from personal experiences.

 

Now see you suggest the gsr trans when the first two gears are the same size. I've done some research and on the street where my acceleration counts I've already got the same gears. As for the rest of the gears I'm not trying to race the car just enjoy it. Can you explain why the gsr trans is so much better.

 

3-5 I believe are a longer gear than a b16. making you have less RPM's while cruising

 

I'm not sure about the exact gearing but the GSR trans has a higher final drive, I believe it's a 4.4 where the standard integra trans is 4.1xx. I've driven both back to back and both with B20B's, the GSR trans feels better and every gear is closer and again, you can have more fun without getting crazy. Also the shorter gearing is easier to accelerate when driving normal and keeps throttle inputs lower, meaning slightly better MPGs if you drive correctly.

 

if you know transmissions(trans-axel in our case technically) you can swap in an ls 5th to increase the FD... there will be a notable drop tho so if you're under the 250whp club I don't recommend it if you're tracking at least. next but more costly option is the ITR(98+ spec) trans it has the tallest FD at 4.78 but I don't see them go for under $700 in good shape most ppl ask $8-1k

 

Thank you for the input I've never driven with that tranny

 

I have a gsr with a 98+ itr trans. driving at 60mph, I'm at roughly 3400 rpms. @70 mph I'm at 4000 roughly. it is SUPER short and unless you wanna hear your car scream the whole time your on the highway, I wouldn't recommend it.

 

isn't the usdm gsr even shorter tho(i have it) ? I'm at 4.5Kish at 110K/PH(70mph) and lets not even consider the ys1 lol



+i do have stretched tires/low sidewall tho i may be off in calculation+

 

@b_swapped93 I have an ls integra I have no thoughts of tracking at all. I love these cars just want a little more power. I've thought of the gsr or b20 swap simply to add a little and lower the mileage on the most important part of my car. I'm not trying to be the fastest acceleration wise out there. I spend a fair amount of time in this car on the highway. Whatever motor I decide it'll be all motor due to it's just for me. I'm trying to find out why swap to a b16 or gsr trans.

 

order from LONGEST to shortest is ( at least in Hydro trans)

LS
GSR ( USDM and JDM 4.4FD)
B16
Type R ( Usdm and 96-97 JDM 4.4 FD )
Type R ( 98+ ITR 4.7 FD)
Type R with 4.9 FD

 

then your best bet it a b20 with a gsr trans you do feel a diff between a gsr and ls trans.


@fliptard when you say a tallest to shortest FD doesn't that mean a higher number as in the top speed. Like 98+ spec it(4.7) is "taller" then it's "shorter" 4.4 FD brother.

 

An EX coupe has the same gearing as a LS and 13 less horsepower. So...yes...an EX coupe would feel slower. A CRX...which model? A CRX Si would probably be about as fast as a LS. Again, similar gearing and 34hp short. So....

What is your point? That lower gearing doesn't create faster acceleration? Have you ever heard of this thing called "physics"? Ever ridden a bike?

The B16 trans is way too much gear for the LS if it's a street car. But the GSR trans would be just right. It would make the car accelerate faster and stay in its powerband.

 

It sounds as if the gsr trans would be the most logical if at all. Giving me a little more acceleration without giving too much on the highway. Thanks guys for the input I appreciate it. Sometimes you just need actual experiences from someone to make up your mind.

 

There are some misconceptions in this thread.

DC2 GSR's have longer 2-5 gears compared to a B16/USDM ITR/95-97SPEC JDM ITR trans. ALL USDM Hydro B series VTEC transmissions have a 4.4 FD. JDM ITR 95-97 spec transmissions have a 4.4 FD as well.

The 98-01 JDM ITR trans has the same 1-3 gearing as the B16/4.4 ITR trans. But it has a GSR 4-5 gear. It has a 4.78 final drive.

Confused? Good.

The LS trans has a 4.2FD.

I believe all the 1st gears for any B series hydro trans (JDM or USDM) are all the same.

 

A GSR trans is a good match for a B18A/B or a B20 intended to be driven on the street.

It sucks for any NA B series VTEC engine, however. A B16 or ITR trans in a GSR is just right.

 

@b serious first I came on here to get some personal input from people that have more experiences with what I'm about to do so as to make an educated decision. I've done hours of research on this subject but in the end it comes to personal experience to make the judgement. But to answer your questions yes I've heard of physics and yes I've ridden a bicycle. Thank you for reminding me why I don't come on these chat rooms often as they're filled with people not trying to help but make themselves feel good.

 

I'm just over here like.....

 

I clearly gave you the most and most complete info. You're welcome. It's no wonder I'm #1.

 

Thank you to everyone that replied and didn't treat me as a misinformed teenager. I appreciate your input and everyone have a wonderful evening
