Hi, would it be worth the $800-900 to invest in a B16 gearbox and some 24.5" slicks +few hundred or should i just continue running my LS gearbox and 22" slicks? And put the extra cash elsewhere..

Plan on making somewhere in the mid-high 300's with a b18c and rods/pistons.

Wouldnt long gears and a smaller tire be almost the same as shorter gears and a taller tire?

Sorry for my ignorance if this is a completely stupid question

1. It's not a stupid question. If you are low on funds, this is a very important question to be asking.

2. It'll all depend on the setup and how you can get the car to drive. My brother's friend was running around 360 whp and an LS tranny, and I lent him my 22" slicks. And he did quite well. He wasn't spinning too much (1.7x 60's) and went 11.9s @ 117 all day.

But basically, to know if anything will help, you'll have to get the car out there and try out each. Or you'll never know truly what worked better.

Personally, I'd run a 23.5" slick and GSR tranny. Meet in the middle.

Thanks man, any idea on the weight of the car with driver etc.?

I will just get the setup tuned and dialed in see what i can do, then if i think it would benefit me i will drop in a b16 tranny (i have to stay cable) and see how that does.

Thanks.

 

just change the fd on the ls, to a b16 4.40 fd. simple cheap, and very effective! it would make your ls, feel a little more like a gsr

Damn am i ever a dumb ***.. I had a old cable B16 (J1) and 3rd and 4th were shot, so i got rid of it (traded it to the boss of my buddys shop after he mounted my slicks). Shoulda kepted it for the FD.. (kicking my own *** right now). The shop needed something related with the throwout bearing, then they scrapped it.

 

what code transmission are you running now(s1/j1/yi/s80/ys1,etc....)? what car?

 

Oh yeah. Do all LS's have the 4.2 FD or is it just the cable trannies?

I would take a guess that it was around 2450 w/ driver. But it's just a guess.

Yeah. I knew that. I just couldn't remember if all LS's had a 4.2 final drive or not.

 

All cable ls transmisions have 4.40 final drive. Honda/Acura switched to 4.26 in the ls. when they switched to hyro.

That tranny, as well as the SiR's Y1 LSD transmission have a 4.266 FD.

&lt;-- Has Y1 in all motor CR-X, wishing for 4.4 or 4.7

 

Well the transmission is from a 91 LS integra. Im usure of the code, its snowing and im too lazy to go look.

That should help you.. whatever one came from a 91 LS.

 

Something to think about, a taller tire will give you more sidewall. A tire with more sidewall will usually work better that a short tire.

you're wrong
he is right.. the cable 90-93 USDM RS/LS/GS tranny came with the 4.400 final.
Also, never refer to the tranny code.

the '94 and up RS/LS/GS has the 4.266

true, i was thinking of the jdm transmissions!

 

I'm gonna try and relate back to the original question of the thread.

Anyhow, from experience, you will be faster with the lightest wheel and tire combo. A shorter (or smaller) tire weighs less (in most real world situations). However, you may want to refer to the manufacturers specs for tire weights.

Now for your question about long gearing with short tires. This is definitely a good observation, and it's good that you ask this. If you can set your car up to launch with a short tire and considering that you have the proper gearing, then yes, you should be faster. Mainly, it goes back to tire weight, and a few other things. You wouldn't want to put on a tire that is heavier regardless of its height.

Now to wander off into the discussion about gearing. Normally, you will want to select a final gear ratio to achieve optimal finish line rpm. (For instance, if I am only going through the lights at 8700, and want to go through at 9700, I will obviously need a numerically higher final gear.). On the other hand, if my car is taking a dump on the launch or at the bottom of the gear changes, (or if it is sliding the clutch toooo much on the launch or at the bottom of the gear changes) then I will need to throw in a "shorter" (numerically higher) gearset. Another little piece of info you may need to know is that with a "shorter" (numerically higher) gearset, you will get into 5th gear sooner, which results in a higher finish line rpm.

Back to the tire. Run as small of a tire that you can get away with. This is to say, DON'T over tire your car. Been there! On the other hand, run as "long" (numerically low) of a gearing combo that you can get away with (In other words, you don't want your engine to just be screaming and not going anywhere). These things require lots of trial and error. They also require alot of launch data at the racetrack.

I hope this helps!

just my expierience. i had a b16a2 with bolt ons and a 75 shot with a 97 itr tranny 4.4 And on my 24.12 in tall street tire i had consistant 2.2 60's and on a 22 in drag radial and had consistant 2'3 60's. at that time i would just rev the car to 6000 and drop the clutch. lol i know better now. so i prefer a shorter tranny and a bigger tire.

 

Trial and error. It's soooooo much fun!
