GSR Trans + LSD + Carbon Synchros + Rebuild kit and you are set! The LS is a tad to long and with the 4.27 final drive you compromise a lot of acceleration speed. The GSR 4.40 and shaft gearing ratios are a perfect boost combo.

For the LSD, look into an M-Factory unit. The prices on them are affordable and we have a great track record with them. Not one single issue! The Quaife is also a great unit as well as the Wavetrac. They all work great from our experiences and we have installed hundreds and hundreds of LSD's over the years. I have tried them all and don't have a single complaint.

 

I tend to agree, and I've had about 10 or people use these setups only to experience problems in the longer run. (They were the BIG thing in '07) There's no need for this stroker kit for ANY reason. Stick with the stock crank and get the aftermarket rods and pistons for under 500whp, or sleeve the block for 500whp+. That money could go to better parts for the turbo setup itself, and is of much better value than that "stroker kit"..

 

STOP THIS MYTH ALREADY!!!

 

this thread made my head hurt.

 

Depends on the driving you are doing. The GSR trans is better for street driving and time attack or auto cross type racing. For drag racing I like the Ls trans with LSD. B16 and Type R trans are way to short for boost but great for all motor. This is just my personal preference. In my EG with boosted LS I was running consistent mid 12s Best time 12.48 and I was trapping in 4th gear. When the LS trans lost second gear from track abuse I got a GSR and was trapping in 5th gear with pretty much the same times, mid 12s. A good friend of mine had a boosted EF with a B16 and with the B16 trans he would nearly run of gearing redlining at 8k, he was running in the low 12s on street tires. His fix was a LS FD and he put a LS 5th gear in for highway driving but I never saw the car run after the LS FD so I cant say what is did.

 

After saying that, I'll leave you alone. But please understand, you are not accelerating any faster with that transmission on ANY platform. As long as you're understanding that part, and keep that as a personal preference, I think everyone should be happy with that statement.

Glad you cleared that portion up

 

i recently experienced a b18b integra making about the same power as me and i was amazed at the difference in acceleration between his ls and my gsr. gsr for the win all the way. its almost as if im making alot more power than he is.

 

 

lol is he jerking off?? i must have missed that smiley.

 

i would rebuild the trans to handle the 600+

 

i missed this one too lmao.

im almost scared to say it since its almost everyone is at the point of flaming the op for the stroker kit... but.... my build is almost exactly the same as yours. except i dropped a nice amount in a dart tall deck block to keep r/s ratio in check for more reliability if there ever was such a thing once you get over 500hp lol.

i would check out driveshaftshop and mfactory for anything trans and driveline related.

i know going with an ls non vtec will not yield as much power, but some of us either like to work with what we have... or like me like to take a motor with a disadvantage and take it to a whole other level. not many vtec hondas around in my area are making 300+ hp so if i only hit 400 in mine i would be happy, but my goals are alot higher.

 

Oh yeah totally agree that acceleration is not really effected. But my times where since it takes time to shift to one more gear with the LS trans I was consistently more than a few tents faster than the GSR. But of a DD car on low to mid boost GSR trans+Qualife LDS FTW.

 

No, I am saying that acceleration is greatly affected. I'm leaving you alone because of the fact that you're stating its a personal preference.

 

Yeah I would have but I was in need of a trans right away so I could keep racing and not have to drop out of the event that weekend. The LS trans lost second while in the middle of a competition and I was doing pretty well so I wanted to stay in and a friend told me I could use his GSR LSD trans.

 

With an LS tranny, it feels like you're going faster and you're in boost longer because you're putting more load on your motor. Just think of it as riding a bike, with taller gears you're working your *** off to get to a certain speed while shorter gears will get you there quicker with less effort. There's your explanation of why you're in boost longer.

Another thing too is, when I built my 400whp LS running 93octane, I ran crower 404s and not the turbo cams. My compression I believe was also something like 9.8:1. Port/polishing the head along with cam timing makes a world of difference as well has having properly sized piping and exhaust. I'm sure I could have hit 600whp easily had I had the chance to run 110+ octane gas before it was stolen.

 

LOL@trapping the 1/4mi in 5th gear...

 

If drag racing is all one cares about.

 

I SMH at some people in here.

 

I like your analogy. And the reason I think that the LS trans will be better is because a 300hp honda is like having an amateur cyclist riding that bike you spoke of but my 600+ honda will be like having Lance Armstrong on said bike. So the gears will essentially be easier to go through considering how much stronger my rider is.

 

When you've run both like many of us here, you'll know the differences. good analogy, but not the most accurate one.

 

GSR trans with LS final is my favorite. Its a ton better then the straight LS.

You can make alot of a power on an LS head. Dont fall for the VTEC head is "required" to make the power. At 15lbs on E85 with my stock port LS head I'm probably around 450-460.

 

How big of a tire are all the gsr trans/ls motor people running?


I ran a stock sized DOT slick on my ls-turbo hatch and was going into 5th gear a little after the 1/8th mile (7000rpm redline).

If you aren't using a gsr/b16/etc. redline (8000-8500), I would not use a gsr trans. Obviously pending tire size.

 

gsr tranny/24.5 slicks/quafe/cuff/carbon synchros

19psi at 580whp went 144mph

27psi@650 went 150+

car is tuned out to 34psi and 757whp
