Trying decide between ppg or six speed

Looking into building trans on my 2011 wrx cause I'm at my power limit now. Like ppg cause get keep my upgraded clutch and flywheel but like the fact that I've seen 500 hp subies on stock sixer.
Any suggestions cause I can get both from rallispec same price

Something is wrong with your estimates if you're being told they're the same price. The 6-speed is a much more involved swap and will cost considerably more.

I would advise the following "stages" for any WRX guy, see where you fit it:
Stock-stage 2: stock clutch, stock transmission
stage 2 with a blown tranny: stock clutch, upgrade the gears only
turbo upgrade: STi 6-speed. But first, sell the car and buy one with the "STi" option package, will save money.
Track monster: PPG dog 5-speed. And a trailer.

In other words, I would not get an upgraded 5-speed for a daily driven car.

EDIT: I am well aware that the statement of "If you want a WRX with a bigger turbo, buy an STi" is an unpopular statement amongst WRX owners who make up the majority of this forum but in my opinion, it is the correct recommendation. The WRX is well spec'd for it's price and is a lot of fun at stage 2 for a daily driver but it is not as cost effective a platform to go much beyond that on. You will save money in the long run starting further along on the STi rather than the WRX. The WRX's "mod path" should be pretty short IMHO. Now, if you go so far with it that you are replacing everything then I would start with neither. I'd get an impreza body and go nuts from there. WRX owners tend to spend a lot of money upgrading drivetrain components that are already included on an STi.

So uh, which is it? A open differential or Viscous? They're two different things. I think what he's trying to give you is a crap upgrade. Just the gears...while you keep the crap 2011 WRX differentials.

WRX diffs
Front is open, center is viscous, and rear is open.

STI diffs
Front helical limited slip, DCCD center, and Torsen rear

The new 3rd Gens got crap differentials and gained VCD and TCS.

I guess you're in it for a lot of money already. I would ask how much you intend to drive the car. If it's more than 3000 miles a year, I'd say get as close to a full STi driveline as you can. If you are not driving it much, I'd probably go with a PPG helixical cut 5-speed with a stock 5th gear.

My 03 WRX brochure says, "Manual transmission models have a viscous-coupling locking center differential." It also says,"WRX models have a viscous limited-slip rear differential." What year did the WRX loose this?

All right, where is the distributor cap? I need to find the #1 plug wire to hook up my SUN machine.

08 and up lost the rear limited slip diff in WRXs. The STIs are all decked out in the differential department.

There's a lot of wisdom in this advice.

There's nothing wrong with daily driving a WRX with upgraded 5 speed gears. I have Albins helical gears in my car and I can barely hear them whining when I'm just cruising around town, but to me, it's an extremely pleasant sound. I envy those who have super whiney straight cut gears. Bite the bullet, upgrade your gears, and enjoy peace of mind. It sucks being broken down on the side of the road - been there several times

Mind me asking what power you are pushing on those gears and for how long thanks
