yeah, so that will be the Legacy (aka H6) setup after you get the bracket...that will give better balance...definitely help reduce your front nose diving upon braking. I can't wait to throw on my brembos...not looking forward to installing the larger brake cylinder, though.Idaho wrote:No, just the damn stock setup with stainless lines all the way around now. I did get some Hawk HPS pads for back there though. I have some old school legacy GT rotors which I got from the dealership to put back there. Same size, just vented for a bit better performance. Unfortunately I had the luxury of finding out that the rotor is actually barely too thick for the stock bracket.... So I have to get me a new bracket off some legacy or what not from a junkyard to get that setup going. Should be decent once I get that going.
A rather interesting turbo pick. I can see getting a TD05 18G (7cm or 8cm) but a TD06? That will spool pretty slow and the 40lb 18G wheel isn't great at the top-end, unlike the 44lb 20G. If you have some time before you install, I'd say have a 20G wheel installed or swap the TD06 for a TD05. Here's the problem: On the 2 liter the TD06 won't reach full spool until around 4,500 RPMs which leaves you just 2,500 RPMs to enjoy the rush. You will likely get similar power output as my TD05 (8cm) 18G but at the expense of lower torque and slower response. Not trying to dump on your choice, especially if you got a deal, however, there is probably a good reason you don't see too many folks running those turbos on 2 liter WRXs.Idaho wrote:Well, just pulled the trigger on a TD06 7cm 18G with a PnP and only 15000 miles. Found a killer deal and figured it would be a fun upgrade!
Really? that seems like such an odd thing to do. Your going to swap fenders, hood, scoop, bumper, lights and grille to look like a bug eye? Don't get me wrong, I love my bug eye, but I that seems like a big investment for a regressive look.Idaho wrote:Going to be swapping the front end out for an 02 bugeye front! Always had a special place in my heart for those front ends. Plus, be able to have the option of a nice lip or two now along with some projector headlights.
There is some benefit to bigger front calipers and rotors. The initial bite and hold on larger brakes (such as Brembos) is noticeably better than on the stocks. If your trying to scrub 30-40 mph in a hurry the fronts do most of the braking (close to 85%). The larger fronts will make a big difference in that case. The problem lies in balance. In a straight line the larger will be better with all other things being equal (rotor thickness, venting, same pad material and wear, etc.) However, the difficulty comes from trying to balance front to rear bias, weight transfer as well as traction to the drive wheels. On a FWD car the fronts are pretty much all that matter. The rears can help keep the rear planted but by and large they are not doing a great deal to help "stop" or "steer" the car. A RWD it is far more tricky. An overly biased front braking system can cause a RWD car to become very tail happy in any braking situation as the weight transfers from rear to front. Add steering into the mix and it gets even more complicated. AWD cars are a mixed bag and there are very few hard and fast rules that will apply to all makes and models. The WRX is an interesting case in point, the Brembo package on the STI is significantly larger than on the 02-05 WRX. The front Brembos are 326x30 vs the WRX 294x24 (over 10% larger and 25% thicker) the rears are 316x20 vs. 266x10 (nearly 20% larger and twice as thick). Draw what conclusions you like. The STi may be more rear biased based on it's dif, and perhaps the larger rears help balance that.Mr Kleen wrote:Overpowered front brakes can actually increase your stopping distances. a lot of the science behind building a good brake system is counter intuitive. Grassroots Motorsports and Car and Driver both ran articles about upgrading brakes in the past couple years.
I hear you, price was the reason I picked up my TD05-18G 7cm as wellIdaho wrote:Yes, price was a large factor in choosing the particular turbo.
600 shipped for that turbo which has already had a port and polish with only 1500 miles just seemed too good to pass up really.
Unfortunately with the TD06 choice at the time of purchase I didn't have many resources to get a second opinion on the matter. Nasioc is always there, but that place is a cluster crap of opposing opinions that often blocks out much of any useful information.
As for the front end, surprisingly a sedan guy wants to swap. So I'll get flared fenders which is what I was after anyways...
I've found a few threads on doing the swap, basically just stripping everything down, drill out the spot welds with a spot weld bit, swap cores, swap headlight connectors, and the re-attach all.
Are you certain yours isn't just a TD05 compressor wheel in a TD06 housing? I know they do those for cheap...but some say you get a little better power out of the larger housing but still get the quick spool of the 05 wheel. Any pics?
