Default Build Order Question.

I am slowly working my way towards stage 2 but had a question about build order. I'm already running stage 1 tune with an SF intake and recently ordered a Cobb uppipe and Turbosmart BPV. I was initially planning on purchasing a Cobb TBE/downpipe but I want to make sure I have all the appropriate supporting mods. I know I technically just need the downpipe to run stage 2 but I don't want to have any reliability issues. Essentially I want my WRX to be as close to bulletproof as It can be. I don't track the car, do AutoX or take it to the drag strip. Its my DD and that the way it will stay. Never been launched and no plans to see If I can rip the transmission out just yet.

I plan on getting a Grimmspeed or Cobb EBCS, Process West TMIC, and Crawford catchcan at some point. I would rather overbuild then worry my mods are going to create problems.

My question is...should I get the AOS, EBCS and TMIC w/ protune when I purchase the TBE? or would it safe to run an OTS stage 2 until I have some extra money to purchase these? Is all this even necessary?

I could buy everything at once but will require some extra time to save up that kinda cash and I'm impatient . Also anything else I should consider doing for safety's sake/peace of mind? I really don't want to worry about blowin a ringland or something but won't have the money for a built engine for the foreseeable future.

Please don't say "Pay to play, if you don't have $10,000+ laying around leave it stock"... that's not helpful lol

You could return the up pipe as it really does very little for you. (IE a few hundred RPM quicker spool on a good day)

You don't need to have an AOS during a protune. It would be a good use of money to protune with the TMIC and EBCS.

Thousands of people have run OTS stage 2 without a single issue for well over a decade, I think it's safe to say that it's safe.

Thanks for the quick reply. I realize I'm a little paranoid and a few of these mods are overkill but I'm glad to hear that OTS stage 2 is a safe option.

You can install the TMIC without tuning, but you will need tuning for both the EBCS and the downpipe. It would be worthwhile to do both of those at the same time.

I would recommend upgrading the fuel pump... it's not expensive and is easy to do yourself.

Somewhere down the line I would like to explore larger injectors and fuel pump so I can run E85. Would like to hold off until Cobb figures out this Flex Fuel thing there are reportedly planning, but since were on the subject what fuel pump would you recommend? I hear alot of talk about the Walboro 255.

Don't get an AOS unless you need it. If you have lots of blow by then get one, otherwise forget it. I didn't need one until I went with a built motor.

I wouldn't even bother with a dyno tune for weaksauce stage 2 tune, get an etune from someone who is known to be good and youll be fine.


Stage 2 or whatever you want to call it, just needs a better flowing DP and a tune. that'll be 90% of your gains. Toss on the ebcs while you're at it and if a new tmic makes you feel better get one of those too.

having the cash also helps, since these cars are turds until you spend some serious jack.

For your car, Walboro 65c.
