i have a 91 integra with a b16 swap thats chipped and tuned with the HONDATA 100 software. its great off the line and around town but in 5th gear at just over 100mph im a 6000 RPM. any trans ideas like a 6 speed or anything i can do to drop the RPMs at high speeds?

You can change the 5th gears to the LS longer ratio.

i hate asking stupid questions but what does LS mean? is it a kit or can i buy a trans that has LS gearing?

The Acura Intergra LS model has a longer gear ratio than the B16. You can install the two fifth gears from an LS to lower the RPM in 5th gear and keep the close ratio 1-4.

i visited the website and was looking under the custom gears section. is this where i should be looking and if so which application would be good for me? i noticed last evening i was at 3500RPM at 60mph in 5th gear. i dont know if that info will help steer in the right direction of what to get but i thought i should provide it. thanks for the help. also is there a complete trans i could swap to?

ok. so im probably gonna replace the whole trans. 3rd gear grinds alot when im going into it. so what trans should i get that will bolt right up to the b16 and into the car without modification?

There should be a gold or white sticker on your transmission with the OEM ID serial number. If it is a 88-91 cable B16 it will have code S1/Y1/or J1. You can install a USDM 1990-1991 Integra LS transmission with longer gears code S1 or A1. If you have a cable 1992-1993 B16 it will have a white sticker code YS1 and you can install a USDM YS1 1992-1993 Integra LS cable transmission.
