Have any of you heard or tried this?

Have any of you heard or tried this mod yet, the jdm GTO MR gears some how you can switch the usdm 6spd gears to the jdm gto mr 6spd gears. Well to know what I am talking about the people at 3si.org are talking alot about this mod and it really helps them out. I have also got a question I have a 92 vr4 with a 5spd right well Could I switch to a 6spd transmission? and do the gto mr gear change while I am switching out the trannys? Go to the 3si.org to see what I am talking about its named If you don't have the MR gears yet, get em!

Yes, it has been discussed on here before:

"As far as I know, it can only be done on the 6spds, but all you need to do is get ahold of a 5spd rear and the front differential JDM* ring and pinion gears (through Kormex) All in all, they say if you can drop a tranny on your own, and are comfortable with working on one, that you can do this for around $300...the advantage being:

1) The MR runs 12.8ish in the 1/4 stock...it's only differences are the gearing and some weight savings...so the gearing contributes almost a half second difference in ETs.

2) For those with higher trapping cars, who need to shift into 4th near the end of the 1/4, this shorter gearing allows you to get more 'ummphh' out of 4th, so that it is a help, not a hindrance.

Here are the threads:

Just wanted to share, as it offers another option to those whose who have/will have issues with shifting into 4th in the 1/4, rather than retuning your ECU to 8k rpms."

As I said in that quote, I think it can only be done on 6spd trannys, but yes you could swap the trannys. If you check out 3si, there are swap guides available as well.

As far as I know, nobody on here has swapped in the JDM gears yet, but I know I have been considering for the future.
