Just wanted to add that you will need a B series tranny for the swap and while you MAY find a good deal on a "nice" GSR tranny the chances are it has grinds, no LSD and needs a rebuild....if such is the case just go to
www.gearspeed.com....there is a redirect site to the Honda specific side but you will see a FRESH GSR tranny with CARBON COATED synchros and brand new seals etc...is 1195 + 300 core (try finding a broken GSR tranny for even 300...I cant) 1495 for like new trans with sweet synchros...add a nice LSD for just 700 and you have a quality setup for $2195 that will put a smile on your face
You can even have them drop a Final Drive in before they send it to you....just depends on your budget...open diff is fine if your on a budget but if you can spare the extra $700 for the LSD its worth it...its a Quaife type diff (not obx) and is way stronger than the stock diffs
I dont feel like buying used garbage and going through the hassle of reinstalling transmissions and axles and driving around with grinding synchros....bugs me
