Frequenflyer,Greetings and Happy Holidays,
Very new here and to the Subaru world. I have owned a modded, 300 whp Mazdaspeed3 for the past 11 years that I still have, but just picked up a low-mileage '17 WRX Premium to daily drive. I have been reading through lots of these threads about mods and have gotten a good idea of what it takes to make a safe Stage 2, 310-330 whp in this car on 93 octane, but the ambigiuity for me sorta lies within "what order" should I smartly do these mods in. That seems to be what this thread is for. As with most people, I don't have the funds to go all out now, but probably willing to spend $500-1,000 at a pop every so often to get to my end goal. I am not including styling/engine dress up mods in this because that is mostly subjective and straight forward.
The suspension side of things seems straight forward and not much different than any other car I have modded. Springs, dampners, swaybars, endlinks and bushings. Any gotchas with this car's suspension? Priorities/concerns/avoids? Is a strut brace and pitch-stop mount worth it?
Moving on to the transmission, I plan on working on the shifter, whether it be with Perrin's products or a whole new assembly like the Boomba. It will probably be one of the first things I do since it won't require a tune and I can get my money's worth out of it every day even at stock power levels. Any suggestions on going in one direction or the other?
As far as engine mods go, I don't want to have to do things twice or spend more money later on because I was near-sighted and wanted instant gratification. Of course, I have never made that mistake before. As with some of my cars in the past, I have installed a mod and later thought, "I should have just spent a little more and installed the other mod I wanted to install while I was in the same area". There are just certain areas of an engine bay that are a pain in the nuts to get to and it helps to group mods, when able, in order of installation convenience though, obviously some of those will need a tune. I know some tuners out there like MAP offer OTS tunes when you buy their Stage packages, but once you start mixing part manufacturers you get into a grey area. I would rather not spend ginormous amounts of money on the dyno. I do have Cobb AP experience since it is what I have used for almost a decade now on my Speed3 with good results street tuning, but it appears to me the Soobies are a little more finicky with the quality of the tune.
So for the people who have done this many times before, in a perfect world, what would you do or what did you do that you would have done differently knowing what you know now? Why did you pick the Grimmspeed intake or EBC over the Perrin models, ect.?
Lots of holiday sales right now with the online vendors, so I am ready to get started. What I am thinking of doing to start things off are the Perrin rear shifter bushing, shifter stop and solid shifter bushing, along with a new shift knob. I'd also like to do their strut tower brace, 22mm rear sway bar and front/rear poly endlinks and finally their pitch-stop mount.
Thanks for the inputs!
The first item a purchased and installed on my 2017 WRX was a Kartboy Cable Shift Arm W/Bearing (P/N KAB KB-20-WRX) for about $112.00. It reduced the shifter throw by about 50% - well worth it. Then I went to a K&N Air Filter P/N 33-2304.
Enjoy your new ride.
