Default Critique my plans please…

I own a completely stock 2005 WRX (5 Speed) which is my daily driver and my goal is to make it into a much better daily driver. I really want to focus on quicker spool up and getting more overall power to the car. Here are my plans and I would love some comments/suggestions.
1. Cobb AP (with OTS Stage 2 map)
2. Borla Hush Exhaust (I want it fairly quiet)
3. Aftermarket Downpipe
4. Aftermarket Uppipe
5. Deadbolt Port and polished stock TD04 Turbo
Am I missing anything here?

get it protuned after your install for sure. The OTS maps are decent but won't compare to a good protune. Also might look into a slightly larger intercooler, that way when they protune it they can lean it out a little more and it still be on the safe side.

Sooooo....I'm planning on doing all of this in one shot. Am I wasting my money buying an Cobb AP unit if I know I'm going to Protune it a few weeks or a month later? Can they load the custom map on the Cobb AP?

imo, do it yourself and in steps.

1- AP stg1
2- up/tbe stg2
3- pnp td04 + protune


The AP comes preloaded with ots maps, they are ok. Protunes are tuned specifically for your car = more powar. There map's which the tuner will save on your AP and you/he will flash it onto your cars ecu.

You need an upipe for sure... Order one now. THe perrin is nice. The TXS is nice.

You need a downpipe for sure order one.

You need a good cat back. I like the greddy EVO catback. Its supported 500whp and makes very little noise. Greddy just filed bancruptcy.. Not sure if you can get one or not.

Tune next. Cobb AP2 with protune map.

Dont bother with moding the stock turbo. Trash it and install an EVO3 16G turbo, STI pink injectors or 06 to 07 WRX injectors, a walbro fuel pump, and a new protune. This wil get you a solid 100whp over stock and maybe 120whp over stock.

^^^^^

Clark, I'll agree with everything except your advice about the turbo.

The OP clearly states that they want quicker spool and to get more overall power. It isn't indicated if that's peak power or "under the curve" power.

While the E316G is the best all-rounder for a high-output USDM 2.0l setup, the spool will not be quicker than the TD04 < ---- nothing is.

The OP can't achieve both goals as stated -- extra power requires extra lag, period.

For lightning-quick spool and more power under the curve, nothing beats a p&p TD04 on a DD. There's a very slight overall power gain, but it's more about shifting the curve to the left. Just touch the gas in any gear, and you're gone. Not fast, but very quick.

If the OP can live with stock levels of lag, their best bet would be a p&p/coated SMALL 16G.

The Hush is NOT quiet....read the Exhaust FAQ for better options or get the Greddy EVO if you are lazy and don't want to compare as it is damned quiet. Clark and Spenk above offer compelling arguements...read them both carefully, but I'd still side with the route you already have mapped out. TALK TO YOUR TUNER about this route and see if he has any find tuning he recommends....read my Tuner FAQ for more prior to tuning help and information.

Thanks a ton for the replies! I have a few follow up questions.

1. Can all pro-tuners save a custom map to a Cobb AP? Both Version 1 and 2?
2. Reading all the posts seem to indicate that the Cobb Stage 2 map gives a nice extra punch all the way to redline, this combined with the Port and Polished stock TD04 seems like a perfect match without having to buy all the other supported mods for a bigger turbo. How many people have gone this route only to get bored with the overall power a few months later?

(1) Protuners are people trained by Cobb to tune your car, their "maps" are know as protune's. Those are saved to the AP. Version 1 & 2 are redesigns of the AP. 2 is just a newer model although it does have a few features the version 1 didn't have.

(2) stg2 is a nice bump from stock levels. Although a OTS stg2 map, with a pnp turbo eehh, you should get a protune to maximize your gains.
We can't tell if you will get bored with that setup or not, maybe go to stg2 and a protune first. Drive it for awhile and decide if you want to swap turbo's or not.

^^^^^^^^^Nicklz is correct.

Running a P&P TD04 with an OTS map is a waste of time and $$.

I went to S2 with the stock turbo, gutted UP and a shorty Crucial DP and was then protuned with 1-step colder copper plugs for some nice gains.

The following year, I finished my exhaust, and was tuned with the following:
Walbro pump
DW650 injectors (I'll go the 16G route, eventually)
p&p&coated OE exhaust manifolds, Grimmspeed coated x-over
APS inlet
PWR tmic
MBC
p&p&coated TD04

The car is a serious hoot as a DD, with the midrange power and response of a small V8. The low end and spool are simply rediculous, and the car still makes 13psi at redline.

Whenever I ride in a 20G or T3/T4 car and feel boost hit (usually at ~4,000rpm), I think, "Daaaaaaamn. I gotta get a Evo3 16G...right now!"

Then I get back in my car and realize that making useful boost from 2,000-7,000rpm with virtually ZERO lag is pretty cool, too. It's so smooth, you don't realize how quick it really is
