What To Upgrade Next?
 
Hello there. I have a 07 WRX TR that is completely stock apart from CAI and Catback Exhaust. What would my next step be in upgrading performance? I'm a newbie so I need opinions.

Tune should of been done first!

After that a downpipe but you'll need a tune for that too so do it same time.

Pull the elbow off that CAI going into your fender and shove the filter onto the pipe instead. ;)

But seriously, get a ram air intake. It's not your intake's job to cool your air, it's your intercooler's. Make your intake unrestrictive to the turbo, and let your intercooler cool the hot air from your turbo.

Start searching EM (Engine Management) Its a must for these cars. Once picking it start working on other things for the car (i.e DP, bigger I/C, 3-port BCS) Check this link out:[url=http://forums.nasioc.com/forums/showthread.php?t=533787]Unabomber's Manifesto - NASIOC[/url]

Thanks for the advice. After all of those things are taken care of, some people tell me to upgrade to a bigger turbo. Is this the way to go? And if it is, what turbo would be best? I want to make around 350 BHP. Nothing to ridiculous but I would like to be faster than a stock STI

You won't be able to just slap a new charger on there and expect it to run like a bat outta hell.

Read Josh's (newtothegame) post and the link. Then come back.

Paul is very right in plainly stating you cant just put parts on the car and expect it to go. You need to research the parts, what works together and what doesnt, also understanding how it works helps alot also. If you have questions about it, read and search, and then come asking about clarifications or for other members personal experience(s). Many on here are very knowledgeable and have nicely modified cars.

Sweet! Thanks for the advice guys.

350bhp you can do with used STi parts. You'll need the intercooler and the turbo (vf39 or vf43). You'll probably want to purchase a fuel pump new, no point in getting a used one. You'll also need injectors, easiest way is to trade yours for some modded stockers. Add to that all the exhaust stuff (downpipe, cat-back) and a tune. You can even use the cobb AP as a tune for that setup if you buy the EXACT right injectors and ditch your intake.

newtothegame 01-05-2011 09:42 PM

Mosc is right about being able to use most the STI parts. Only suggestion I make is about the injectors. If you do happen to buy used ones, be it modded stock ones (I dont recommend) or actual aftermarket set, be sure to have them cleaned, inspected and flow tested. Wouldnt do you much good to buy some used injectors, install them, and them be faulty/junk.

i didnt see this added so ill do it.

i know you said you wanted about 350HP. my VF-52 has the same flow rate as an 08+ sti turbo. that being said right now im at 330HP and 360TQ with the following...

Pro tune
TurboXS CBE
Perrin light weight pulley
Invidia catless DP
TurboXS CAI
Gimmspeed 3-port EBCS
Walbro 255lph pump
NGK 1 step colder plugs
TurboXS FMIC
TurboXS RFL BOV
custom blow through
custom oil catch can venting both crank and valves to atmos
Grimmspeed EWG/Tial 38mm

im also still on stock injectors which are 565cc at 94% duty cycle. im saying all this because only being at 330HP my torque is 360, to me thats to much for your tranny. if you tried to go to 350HP your torque could be over 400TQ. 350TQ is a good max for your tranny with shifting very gingerly. your tuner can back down the torque low end and give you more top end HP but just keep all this in mind.

^He's talking BHP though, which would probably be in the low 300 whp area. Either way he's taking a chance with the stock transmission.

brfatal 01-06-2011 10:46 AM

350 bhp = +/- 270 whp

newtothegame 01-06-2011 11:47 AM

Which given that number the transmission will hold up just fine if treated right. You can still drive spiritedly and have fun with the car. Just no clutch dumps, and keep up on maintainance.
