STi Turbo VF48/VF39 on my 07 stg. 2 WRX- What do I need??

[chitownej]

Hey everybody!

I have an 07 wrx with about 86k miles. Im running a HKS TBE, SPT intake, and Dyno tune at 240whp/320wtq. Stock oem clutch, stock internals, stock TD04.

After discussing on here and with the tuners, the general consensus is that is you have an 07 Wrx you need these to support VF39,43,48 turbo...in addition to a TBE, and intake if already installed:
STi TMIC
Fuel Pump
Turbo inlet
Turbo itself
TUNE- dyno>street tune

Meth is simply another way to cool the air that gets put into the engine. It also increases the octane of the gas in the cylinders as the meth cools off in there. I would also suggest wrapping your downpipe and turbo to prevent heatsoking the TMIC. Meth does require tuning, so definitely budget a tune in there as well. Just make sure you either have a guage to tell you how much you have in the tank and/or a map tuned for when you don't have meth. Aquamist has an awesome meth kit that comes with a few failsafe features, so definitely check into them.

As far as tranny and clutch go, this depends on how you drive. Stock can always hold fairly well unless you like dumping the clutch at a stop, which would require stronger gears/clutch. Upgrading the fuel pump and injectors would be a good idea as well since you plan on getting a better turbo.

EDIT:
I would definitely do the 50/50 mix.

Thanks mr wrex! No I usually baby it for the most part....I never dump the clutch once yet.....
So what if I were to put an sti Turbo forgetting the meth
Besides sti turbo on an 07 Wrx with a TBE, what else would I need? I heard internals are same as an sti so is it a direct bolt on?

If you're doing the vf39, your stock injectors should be good.

Things you'll want/need to add:
1) fuel pump
2) boost controller
3)heat wrap

P.S. My name's also mike. Too many dam Mike's in this world

and at least an sti tmic. and you should also do a new inlet since you'll be in there.

Lol nice! And okay and heat wrap what the DP and UP? This is needed to keep the heat in right?
I don't need to upgrade bov, ewg at all?
And do I NEED a boost controller if I have a "conservative" tune?
How many whp/wtq should I be at with this setup? I'm already at 240/320 I wanted to get 300/350 and I hope I don't blow diff with that power :/


Anybody else input or confirmation would be a big help!
I want to do the VF48 instead of 39, I heard lots of problems with a 39, and being a college student I need a reliable car!
Sti tmic and VF48, plus walb. Fuel pump

Do I need the heat wrap and BC if its not a crazy summer tune? I'm going conservative so I don't blow it up!

I'm not too sure about numbers but if you hit more than what you want, just tune down the boost I wrapped my DP and UP to prevent heat soak along with getting a ceramic coating on them and although it's not necessary to wrap them, I highly suggest it. A new boost controller is always a good idea, especially if you want to go with the EWG setup. I am installing my EWG with the MBC + EBCS (aka Hybrid boost control setup) tomorrow and I have a thread around here somewhere with the different boost control setups. Get an upgraded BPV (not BOV) if you think the stocker may blow/leak. FYI, the EWG is always beneficial as it is able to control boost a LOT better than an IWG.

Here's that thread I was talking about:
http://forums.nasioc.com/forums/show....php?t=2417761
Page 2 is where I mention what parts I purchased to run my EWG setup as well as a clip of what my car sounds like with my pre-EWG mods

P.S. If you do wrap any exhaust components, they will produce white smoke for the first several heat cycles (aka running your car then letting it cool). This is normal, so don't get paranoid when it happens

Wrong.

Fuel pump isn't needed, WRX/STI pumps are the same. Boost controller is the same, doesn't need touched. Heat wrap would just be for fun.

OP, to go with a VF39 you would need only the turbo and at least an STI TMIC. Otherwise, you are good to go. If you go 16/18G you can get away with keeping your injectors and pump, but you want to upgrade if you do go that route.

Your wrx does not have STI internals per say. The only difference for 06 between the STI and WRX short block is the piston dish. So basically your pistons are different. Heads are different if you want to talk overall differences.

You do not need an up pipe AT ALL. Your stock one is by far good enough for what you want. The net gain is ZERO. It's not catted if thats why you wanted for "precautions."

I'm sure I missed some points, there was a lot of misinformation in here for what you originally asked. If you want reliable, stay with a VF turbo and simple tune. Meth will always run the issue of catastrophic failure to the motor, and an untuned turbo can do the same. You will not see 350 whp on any setup mentioned.

[Mr Wrex]

Hinshaw, you're wrong. I mentioned the pump in case he decided to go with something other than a vf series turbo and maybe a boost controller because I personally hate the stock one. Heat wrap is always beneficial, but I guess you don't think that so go enjoy your heat soak. OP also mentioned a few posts later getting an UP for an EWG, so once again your comment merits no valid info. Also, where'd you pull that info out from on meth? I'd like to see proof how a 50/50 setup can ruin the motor WITH a proper tune of course.

jet-hot thermal coating + wrap is the best way, so dont think heat wrap is the ultimate answer. What Hinshaw said is not wrong. to run a simple vf, that is all he NEEDS. Meth can go wrong at any moment. so many small things can go wrong, and if they do them boom pow engine.

You do realize I correct you about once a day right?

The fuel pump is fine for quite a few turbo sizes. I'm running an 18G on stock fuel pump with no issues at all. What is your experience on an 07 with the pump?

You hate the stock one? Great. Does it do the job? Absolutely. A 3 port would be slightly beneficial for everyday use, and if he eventually gets an EWG. For his original question asked, it would mean nothing. From this thread, it's clear the OP doesn't know what he really wants.

I never said heat wrap wasn't beneficial. My entire exhaust system to the catback is completely wrapped. My intercooler even has reflective heat tape on it. Don't try to tell me about these cars, I've rebuilt enough, tinkered, and read enough before you joined to understand everything. In many threads you spout off a good bit of info that is wrong, while you will admit you are still learning, you still have a lot to go. But if you want to keep comparing e-peens pm me.

[Mr Wrex]

Keep telling me how my opinions and personal observations are wrong. It's quite entertaining

[HinshawWRX]

U mad? Yea, u mad.

Simple FACT: For VF39 you only need the turbo and a tune.

[chitownej]

guys guys, you're here to help me not fight! jeeeeez! Come on now!

I want to go with the turbo setup instead of the meth, just screw meth inj. all together, too many problems I think.

So if I have an 07 wrx, HKS TBE, SPT SR intake, dyno tune now.
If I want the VF48 turbo(Less shaft play, doesnt crack as easy, correct?),

I just get the TMIC, good dyno/street tune and ill be okay?
I think the main internals are good enough to support this basic upgrade...I would get the sti turbo, NOT a 16G or 18G at this point, Im thinking the 48.

I would probably get a 3 port boost controller from the tuner before the tune, install it then tune.

I know Id need a better BPV since the turbo will be pushing more psi, thats assumed. What do you guys reccomend in terms of a bov or bpv. I had an HKS SSQV on my bugeye but I think it was a f'in knockoff because it just didnt work right hard to explain, sometimes it like fluttered and fell off, etc

I wanted to get the uppipe just to have the entire exhaust flow being 3" throughout, and stock Up's arent good for the turbo some people say...

So with a VF48, TBE, intake on, I need sti TMIC and dyno tune? with a 3port BC

You can't have an opinion on facts. the facts are the facts. i don't get it.

[jayman4312]

The stock up is fine on your car, it is catless. they arnt good on 2002-2005 wrx.

keep the stock bov, hks bov is a piece of garbage. stock will work fine.

Have the tuner put on a 3port if you can afford it, it is a good upgrade.

you just need the turbo and an sti tmic. your internals are fine for a much bigger turbo than a vf.

THIS is what I was looking for!! Thanks jayman, what part of chicago are you in? Im in St. Charles, do you go to 6star? Andy and brian do my tuning there, So I literally only need VF48, STi TMIC, and a dyno tune? Thats what I figured, but I will ask them to make SURE. Might get a new bov since the sound is good, not pos HKS though, tial or something probably
thanks any other confirmation would be nice on this!

You have a metal BPV stock, if for whatever frankenstien reason it were to start leaking, look up the 2 cent mod where you essentially hit it with a hammer, then put it back on. 02-07 BPV's rarely leak or fail. You won't be pushing near enough pressure to cause an issue with it.

If you want a BOV for sound, you're doing it wrong.

If you already have a tuner, call them instead of making the thread and ask them since they will know 100% and not give you 5 different answers.

So lets recap, in order for this to work you need:
-Turbo (VF39 or 48. Honestly doesn't matter which. 39's aren't bad at all, and a bit cheaper)
-STI TMIC or nearly any aftermarket TMIC
-Tune

What you do not NEED:
-3 Port BCS (can throw one on if you REALLY want it)
-Fuel Pump (Same thing, only if you want it for poop and giggles)
-Injectors (Useless at this stage)
-Magical Unicorn dust (overpriced)

sounds gooooood to me! Cant wait! I heard VF48 is much more reliable though! Im gonna get sti TMIC with the 48 probably then dyno tune....

ALSO-- Will I ruin my rear diff, clutch, or trans with this? Ive got 5 speed on an oem clutch, stock diff and trans obviously...

any appx's as to what I should see with vf48, tmic, dyno, tbe, intake? My buddy said 300whp/350wtq...Im at 240/320 how it sits just with intake and tbe
Mike

Get a vf 39 or 43. You will need some kind of boost control, ask you tuner what they prefer, a fuel pump, and at least an sti tmic.

I recently did a vf43 swap and made 290wph/345wtq on a mustang dyno.

You can find my graph in Cobb's database. I'll pm you the link if you want.

[HinshawWRX]

Guessing WHP output is useless. Wait until you get it tuned and see what you make.

And also guessing what you may or may not ruin is useless. The transmission is based on your driving habits (and those of the previous owner if there was one). Clutch is dependent on wear and habits. The rear diff is actually really strong, and you shouldn't see any issue from it accordingly.

For reference I' running a semi built motor, 18G turbo, stock transmission, and only an upgraded clutch because the stock wore out. No issues.

I live in brookfield, so not too far from you!

Talk to dewey at 6star, he knows his stuff. thats a good shop, listen to what they tell you.

[Dave D.]

Sti intercooler and splitter, VF39,tune, and you're ready to have some real eye-opening fun after that TD04.

Ill check online thanks though since all synod and tuners do their work a little differently! Thanks
Mike

[chitownej]

Kaufman: nice ill give em a call now to confirm
Dave & hinshaw: cant wait! I didn't know it would be this simple! lol

I never dumped clutch or launched and never will! I baby my car really and have only raced once since I bought it a month ago, clutch seems very strong and so is diff and engine. Should be fine, ill go stg 2 clutch when this poops out
