WRX Tranny

but does the cryo treating they do on the RA gears do anything for thier ability to handle a bit more power? curious

 

I wasn't aware that RA gears are cryo treated. If that's the case, then you might as well just get a set of '04+ gears and cryo treat those.

Yes, cryo treating will help strengthen them.

 

oops, not cryo treated, but micro polished....through rallispec. sorry

Only Rallispec RA & STi gearsets feature the REM isotropic superfinishing process (micro-polish) now treated entirely in-house. ISF provides substantial benefits in terms of reducing gear tooth friction and eliminating surface imperfections (stress risers). REM ISF is used extensively at the highest levels of motorsport (F1, WRC, Nascar). Our real world testing has shown huge improvements in reliability far beyond any other surface treatment we have tested.

 

Upgrading your WRX gears would be ideal if you bought PPG's or the new gear set in the process.

Everything else is a waste ie: RA gears and cryo treating....

 

thats funny, i raced a firebird with NOS (at the track)* 2 weeks ago and he was wishing he didn't. i had 3 car lengths on him in 60ft.

 

DUDE edit your post, nobody needs to know WHERE you raced the fool.

 

LOLZ....thank you

 

it was in an underground parking ramp durning the wee hours of the morn in Tokyo

 

Completely and utterly true.

The 6mt has gears almost twice as wide as the 5mt, with a better tooth profile. I like it, and it shifts like butter.


PPG's are a phenominal gearset as well. Better metalurgy and a tooth profile that keeps the force more normal to the tooth throughout the mesh of the gear.



Those two are the only options, imho, for upgrades. Everything else is a waste. If you don't believe me, call Andrewtech and ask them how many broken RA, micropolished, cryoed, '06+(or whatever) trannys they get in. I really want their 6mt dog gearset, but they $10k is a little out of my budget right now:eek3:

 

Sorry to hijack the thread, but is there a site or resource I can use to see exactely what 6-speed trannys will work with my 2004??

 

All will work, its just a matter of getting the other parts to retrofit it. I can make a list if you want

 

heck ya!!!! thanks a ton.

i really would love to buy the ppg gear set, but contemplating on it since the sti swap wouldn't be much more

 

5mt has better gearing, throw ppgs in and it would make a perfect, near bulletproof setup.

 

true, but let's say I end up pushing 400 at the wheel. will the case hold the torque? also, the r160 will explode, won't it?


bugeye386- very sorry to take over your thread....boot me if you want.

 

^ Also true. There has been a lot of debate on this topic, but its all BS.

 

+1. the 6spd have what a 3.70fd or a 3.90. I must insert that 4.44 is FTMFW! (4.11 is also good) My ideal setup is the V6 JDM STi 5spd 4.44FD LSD and DCCD. :drool: (maybe ppgs if the stock Ra gears break)

 

I love the 4.44 FD in my Baja Turbo 5mt in the '02 WRX. Its held up really well to "stage 2" STI power levels but I don't drive it like a ham fisted, knuckle dragging, mouth breather.

My ratios are almost identical to a '04 USDM 6 speed which I like but I wish I had a sixth gear for highway cruising because 80 is the new 75mph. I think a 6 speed is in my future though.

 

^^^ what do you mean you had??? dont you still have it?

 

BACK ON TOPIC... for Alex's(bugeye35whateverTF)....ALEX you are worrying too much, you guys the car is basically stock, the vf39 upgrade, the kid can drive a stick, and he doesn't drag it....HE IS JUST FINE!NOW GO BUY THE DAMN CAR

 

haha. Thanks Will. I know ill show it to you next week...
