no way...gsr has shorter gears, id go with the ls trans

Exactly. Shorter gears mean faster acceleration. The GSR transmission is pretty much a compromise between an LS and B16 transmission. Long gears being better for boost is a myth.

in my experience the gsr isnt as good as the ls. in a high hp fwd ap the longer gears help the car keep traction (not always). the car im speaking of is a 550hp car. it started with a gsr and pulled 11.4 @128 and with the ls it pulled 10.63 @136

( with a little added traction due to the gearing they were also able to add a little boost)

so if shorter gears are better for all applications why doesnt this guy get a b16 and get a shorter gear set? I never said that i though the gsr was a bad idea, just that i didnt like it. but i guess for a street car the gsr wouldnt be a bad idea.

92civicb18b1 · 02-28-2008, 12:10 AM

I can see a long argument if I put another 2 cents in. I'm fairly tired so I'll respond tomorrow.

LSD? Tires? Custom gear ratios for a purpose built race car? I sure know I'd go with those three over a stock transmission and more power. To each their own.

For the 90% of people who aren't building for much more than 300whp, the GSR is the best compromise of long gears and short gears. I kinda thought that was obvious for why I didn't recommend a B16 transmission. But, since it wasn't, many people feel that the B16 transmission is geared too high to use as a daily driver because of where it puts the RPMs on the freeway or highway. The long gears of the LS are good for gas mileage and top speed, but not so good for acceleration. So, you'd want to find a compromise that wouldn't require changing gears around inside the transmission. That would be the GSR transmission.

agreed

AWDrifter02 · 02-28-2008, 02:20 AM

i was actually told to do a GSR trans with a type-r final drive. is that a good idea?? and i was also wonderin if anyone had any tips because im putting it into an EF civic hatch and dont know how thats gonna work since the EF has a cable driven clutch. any help is greatly appreciated. thanks guys.

Not so true Scott. Depending on the turbo size he runs, if he is driving this car daily it would not be very enjoying to drive a turbo ls that will be spooling (depending on the turbo size) roughly around 3500-4000 rpm. For example, if he were going 80 mph in 5th gear with a gsr transmission, his rpm will be at 4,000. That would cause more wear on the turbo itself. Ive had both and I prefer the LS transmission especially for DD. Much better fuel economy and a more comfortable experience.

LS_VTEC · 02-28-2008, 05:01 AM

Now if he wants to race light to light or at the track constantly, the shorter gears are the way to go. For driving distance, its beat.

92civicb18b1 · 02-28-2008, 05:34 AM

I'm glad I came back with the responses I wanted to hear/ Now I don't have to start my argument.

I agree and disagree with ya LSVTEC, since I too have had both transmissions on my LST. My second turbo spooled up around 3.5-4k and I still recommend the GSR. The GSR was noticeably quicker. Sure I was in boost on the highway but the car was just faster and obviously had much better pull with the shorter gears which is what most people want.

The LS still just seemed too long to me, I said differently back then but that's cause I couldn't afford another GSR trans after the ring gear sheared off half it's teeth and I wanted to make myself feel better about having to have the LS.

LS_VTEC · 02-28-2008, 05:46 AM

Like I have said many times in the past, it is all about what the owner of the car wants. Fuel economy and comfort without having to be in boost in 5th gear driving @ 80mph, or more accelleration with shorter gears. Either way, your gonna go fast.

Blanco · 02-28-2008, 08:58 AM

If you want to sacrifce 1st-4th for a comfortable 5th, that's all on you.

What do you say to the person who has the GT28RS that's fully spooled by 2500rpm? Which transmission would be the best for them to keep them out of boost on the highway?

Compromise. You can't have your cake and eat it too, unless you feel like building yourself a custom transmission.

philyphreak2127 · 02-28-2008, 09:25 AM

Depends on the purpose of the car. If it is a drag car I would say si tranny, if it is an autocross car I would have to say gsr personally I wouldn't go with the ls tranny unless you want better gas mileage. lol if you want better gas mileage buy a d-series motor. lol

92civicb18b1 · 02-28-2008, 09:36 AM

if it's any type of race car te b16 tranny would be the best trans unless you're car has has enough power to top the trans out before the 1/4 mile is up or there are super long straighaways on the course your running.

Blanco · 02-28-2008, 09:43 AM

Coming back to this. I really don't see why people have such a problem with being a 4k at 80mph. Both my Si and 325i sit just below 4k at 80mph. So what? They aren't old school domestics with a 5k redline.

elvis8310 · 02-28-2008, 02:42 PM

Ok, I am building or my ls turbo a gsr trans with lsd and using the 4th and 5th gears from an LS trans that way I have the best of both worlds. I think this gives my the highway economy I want but the lower gear to tear it up with. If you got the money this is the way to go in my mind.

jtornado · 02-28-2008, 05:03 PM

What about in my situation. Ill be running Full 3" Ex. Garrett T3/60-1 .48 a/r and I wanted good fuel economy, not spooling on highway and good acceleration??? Elvis I think thats a good idea for my situation.
