Gearbox troubles!!!
Hi all
Just had my car remapped with all my new stuff on it but the gearbox has gone again! The problem is it must be running about 340bhp @ 1.4 bar and has destroyed 3rd gear. I need a stronger box than the sti2 (MY96) has but the problem is it has 4.1 diffs and all the later sti's have 4.4 diffs...my question is...WHAT IS THE SOLUTION???! (without spending a couple of g's on a 6speed)
Many thanks
Stuart

the 4.44 diff is lower geared for more acceleration.................the higher the number the lower the gearing...............
as steve says, easiest is to build a later type box with your diff ratios to suit....

Don't you think andy should personally pick up and deliver my gearbox and diff to me?

I have the same problem with mine 3rd gear went two week after it was mapped to 1.3 bar! Mines a uk box tho, but am after a stronger replacment box, I really didnt wana go down the six speed route mainly because of cost but its looking like the best option for the long run.
Any other ideas on what to change it for instead of the six speed???

Just thought i would update the thread. My sti6 gearbox, 4.4 rear diff and new exedy organic clutch are in and it is really great. It is a bit tight at the moment and i am running the box/diff in gently before using boost.
My thanks have to go out to David @ API for supplying the parts and with such helpful service too
Also have to thank Andy F for the great mapping (smooth as anything btw andy) and also for the help with information (although he did break the damn thing! LOL). He has been great no matter.
Here's to many years of no trouble!

PS David, love the longer 5th....makes the cruising so nice now
