Hey all I'm weighing transmission options here. I am just wondering experiences and opinions. I am making 651whp on my b series setup.

I have been using simply a 4.4 ITR transmission with the only mod being a Speedfactory Scha

Recently I have a sheared a 4th gear, put a gsr one in for the meantime, then broke the diff. in the burnout box.

I'm weighing my options as far as what I should do to be cost effective yet somewhat reliable. I also need to be able to do ~150 in 4th.

My options that I have come up with are:
Keep my itr gearset
Get a handcuff
CC'd syncros
GearX 4.06 fd
Mfactory or Quaife helical lsd.
Torco RTF fluid

Or:
Use a GSR trans
CC'd syncros
Handcuff
Mfactory or Quaife helical lsd
Torco RTF fluid

Or I could save a good while and find a dog box.



I really don't want to go the dog box route so I'm wondering what your experiences are on the stock gears with a handcuff on roughly this power level.
Do you think it is just pointless to do one of these other transmission setups or do you think it will hold for a season or so?

I drag race it maybe once a month and street drive it maybe once a week.


In for your opinions and insight.

Thank you.

Save and get a dogbox...

Fwiw, i trapped closed to 150 before using ctr gears with mfactory 4.0 final drive no cuff...

Good to hear.. Do you guys street drive at all?

Wow.

Wonder how that same setup would do around the 800whp range.

I've been debating on a dogbox setup. I'm glad this post was made.

One of my friends trashed like 5 stock trannies w/LSD last year at a little over 750whp. They'd last a little longer with the cuff in but every one of them eventually **** out 4th gear..

Made 630 on a dynojet. Bone stock gsr trans stock diff oem honda fluid and a comp stage 5. 30 hits last season. Pulled it apart last week to do a Mfactory diff and a twin disc and the thing looked perfect. Lets see if she can go another season.

Get an Albins syncro set if its a street car. you WILL break ANY OEM gearstack at that power if youre putting it down and beating it regularly. Period.


You dont NEED a dogbox, syncroed is fine... Look to the Albins. Its a nice piece. You wont dent it at 650

Yep. I have the same setup and it has been used in my 400whp build, my 620whp build, and last years 738whp build. I will use it again this year as well. I made about 14 passes on it last year and alot of hits on the street. Its obviously on borrowed time, but it has worked for me.
Lol but Jason drives like a maniac! Haha

^troof. Hahaha

Sanman, what kind of weight is that CRX? Weight of the vehicle and overall tire height has a ton to do with this as well. All are factors in the stress on the transmission. Friends want me to take them for a pull on the highway in 4th and 5th. I have a full weight LX sedan. Add another 200lbs from a buddy, that puts me rolling at ~3000lbs. Not good on a stock transmission. Want that thing to last me for at least another season.
