I suppose that the reason why people opt for LS tranny’s is not just to help them manage their engines huge torque during the gear-changes, but to also keep their engine out of boost while cruising. See, my car is highway driven at about an average of 70 miles a day. I travel, normally, on the interstate, but there is a 55mph highway route that I could take which would take only slightly longer to arrive at my destination. The fact that my car travels sooo far everyday, makes turbo’ing it less favorable to me. I just feel that alot of those with turbo cars, have another car that they can drive, or another car that gets them back and forth. It seems hard to rely upon a turbo beast for everyday use.
Anyhow, the thing is, we all know how high of rpm an S1 B16 cruises at, so this should present potential problems for me with my combination, right? I mean, some people are almost getting into full boost at just over 3500 rpm’s. I would hate to be cruising at full boost. WTF?
Or should I just get a larger A/R turbo, which takes longer to spool, and one that lets me use the high rpm advantage that my B16 gives me?
While typing this, I have this feeling that :nobody: LOL
Boost is throttle related, and has little if any at all to do with the transmision. Short geared transmission (i.e. B16’s) are torque multipliers so the LS transmission has nothing to do with “maintaining there engines huge torque.” The reason people often think the LS transmission is “better” is because it helps with wheelspin where the shorter geared just makes it that much worse. They also follow the biggest myth of all which is “longer gears allow you to stay in boost longer!” Stay away from all that bullshit because you will end up with ALOT of false information. All 100% complete honesty, it comes down to preference in driveability. Do a search and you will find some pretty good arguments on this subject.

You can be at redline and still be in vacuum…
Depending on what you plan to do with the car, generally you want the shortest gearing possible where you can still maintain traction, but not shift into 5th gear. Or if you do hit 5th, make sure you’re trap speed allows you to wind out a good portion of it.
On my 450+whp car I am running the JDM J1 tranny. even shorter gearing the the JDM S1
You say that your car has 450whp, but is it a daily driven car like mine will be?
Makes me wonder if I should buy another car just to get me back and forth, and leave my integra parked. The biggest thing for me is reliability. That’s what’s making my decision, not the overall fun of a turbo car. I’m trying to be smart about this.
I daily drive my car with 450+whp. It’s is 100% street car. I drive to the track, race, and drive home. I race on the tires I drive on the street
Tchleung, are you having to constantly work on your car? I mean, 70 miles a day on average is what a turbo setup would have to go through. I’ve just never owned a turbo car. I do know a sh#t load about turbo setups, but I have never had one of my own.
By the way, I really appreciate your reply’s, and your info is definitely valid for this thread.
P.S.- There is a T3/T4 turbonetics turbo that I can get really cheap, along with alot of other stuff.
Well I do constantly work on my car, but it’s not maintenance or because things are broken. I am cosntantly building and upgrading things. But other then that. No I never have any problems with it. But then again. I did build the engine myself and tune it myself so I know everything about the car and setup. Just keep up with your oil changes. I have a tendancy to check my plugs, coolant level adn condition and oil etc etc and quick visual inspection of everyhing once a week. Cause, I do bag on it pretty bad. :rockon:
