Going to be installing and setting up this in Jon’s(DA KING) WRX in the next couple weeks when he finally drops off the car for work. Just going through all the parts now and inspecting everything for damage now. I’ll post more stuff/info on this as the project progresses.
Here’s a breakdown of the parts top left down. These are NOT all included in your typical RA gearset, you need to buy additional parts like syncros and bearings, etc. This also require complete disassembly of the transmission and setting up of the R&P afterwards, so heed the “Not for inexperienced” warning if you want to follow suit and do this yourself.
-main shaft with integral 1,2, and reverse drive gears
-3/4 driven gear
-4th drive gear
-4th baulk ring
-3rd drive gear
-3rd outer baulk ring, syncro, and inner baulk ring
-2nd driven gear
-2nd outer baulk ring, syncro, and inner baulk ring
-1st driven gear
-1st baulk ring
-pinion shaft support bearing
-main shaft taper bearing set and race
-main shaft forward support bearing
-3/4 selector hub and ring
-3/4 shift fork shaft

Only one straightcut gear pair in this set and that’s reverse, rest are helical. An upgrade in the name of saving the glass WRX tranny from grenading from the power of an 18G, another mod I’ll be fitting into this car soon Also reduces the ratio difference from 1st to 2nd improving acceleration. Gears are stress relieved and cryo’ed for a bit more strength and are a bit wider than the stock gears for more torque capacity.
My first '07 suby tranny, but not my first suby tranny at all. 5mt’s easier to work on than the STi 6mt due to their split case design.
325hp and 365tq on the stock wrx tranny might get a lil dicey… hes doing it as preventative maintenance. the RA gearset is tons stringer than the oem usdm suby gears for the wrx…
yeah i just read his build thread and thats a good amount more than stock so beefing up the tranny is definitly a good idea, i know it says a few weeks for this but when is it going to be fully finished?
Jon get back to me ASAP…where the fawk is 5th drive and driven gears??? I can’t remembered if you ordered this set with or without them??? Not in any of the boxes yet I have a spare baulk ring here? I know if you order the set of syncros it comes as a set of five but this still has me worried.
