Invidia will have the upper turbo one in the box. You will need a 3"-2.5" exhaust adapter if using stock exhaust which comes with the gasket. They are sold at Import image racing.

better sealing ability due to the lack of 4 crappy rubber o-rings. add the sti manifold with some phenolic spacers to help reduce heat soak, but the wiring B.S. would steer me away. you'll need an sti turbo, and intercooler to go with it. or if you get a fmic, you'll need custom pipes setup. like bren said, it's alot of work for aesthetics.

[slightlymodified]

Yeah that seems like alot just for that. A-powdercoating we will go! Lol

It's not metal, you can't powder coat it.

quick question.....if i have a Scanmaster O2/Knock censor could that be robbing my signal from my OBD port? i have a scan tool and it reads no signal, also i took the car for an inspection and was told the car wont communicate with the emmissions test....thanks

I have no idea what a scanmaster02/knock sensor is, but if it tampers with the ODB2 signal or splices in wiring wise, of course itll be a problem.

Any Idear what type of gas mileage I should be experting from a tuned 05 LGT auto with a AEM cold air, up pipe back exhaust and turbo inlet.

It seams that my 2002 vf22 wrx (270-300whp) gets beter MPG then my wifes LGT (220 whp).

OK. LGT got 22.6 mpg last tank.

wrx like 24.6 mpg

[bubbahotep7]

How much torque can the STI transmission handle? I see these dyno graphs with 365-385WTQ with bolt-ons...

or is it more likely that the 08+ engine will go boom first at these hp/tq levels...which brings me to my second question:

At what point is a piston upgrade recommended? When you upgrade the turbo? Do power levels achieved w/ just turboback, intake, headers warrant upgrades to the internals?

(All this considering a conservative tune)

Stock transmission is good beyond where many wont push it. Pretty bulletproof till the mid 10 second 1/4 mile or lower. Clutch will start to give out at 440wtq on our dyno given it is in good shape.

Motor: less is more some are flawed / fatiqued already before their build. Pre 07 STi motor seemed to be more stout and go till around 400whp on a dynojet style dyno. 08+ sub 375whp to be safe.

I'm curious as to what I would need to do to set my car up in limp mode. Someone backed into me a few weeks ago and I will be dropping my car off at a body shop to be fixed.
This will be the first time the car has been out of my care and put into the hands of someone else (besides Bren) and having read a couple horror stories about mechanics and
random joyrides, I would not like to become one of those statistics.

[BG @ BrenTuning]

Connect a solid vacuum line from turbo to wastegate, itll run 10-11 psi, so they can't really boost it.

[shamankjm]

Specs: 08 WRX with Ingen CAI (was told it was a special edition or something), turbosmart BPV, Megan catless DP, Gimmick turbo inlet, street-tuned to 19PSI

Issue: when accelerating into boost, there is a fluttering noise; boost is not affected, the car still pulls, but the noise bothers me.

someone told me that it is just turbulence from the intake, but I figured I would ask the guru.

i read in some earlier posts that someone was having some similar issues; however, he had different mods that included a FMIC, which I do not have.

ideas? concerns

thanks in advance, Bren.

19psi is a little much for the stock intercooler and overly aggressive for a stage 2 car. We actually had a car come in similar setup recently and it made MORE power and torque at 17psi.

In the cold winter, you will hear the turbo flutter/wg/surge in the low rpms during boost. The noise is especially heard through the inlet/intke.

well ill be coming to you in the spring once i upgrade to a VF52...

but until then, am I doing any irreparable damage? perhaps I am misremembering; perhaps it was 16psi

Bren, Mike (WRX swapped Green TS you road tuned) is looking into building a 2.5 liter engine to swap in to his car. He would like your advice concerning which heads to use on the 255 block.
His options are:
1: pay 400$ plus shipping two ways to have EQ tuning machine his 2.0 heads to match the 2.5 block
2: Pick up a set of used 255 heads and plug up avcs for about 500$

Both options look to be about the same price, so which do you think would provide better results?

He plans to use ACL race beaings and NEW 257 pistons in the 255 block, Is currently picking up a set of DW 650's, and is looking for a VF39 in decent shape to finnish this build.

Any other suggestions? (Particularly on what turbo to use for an auto-X build with this set up)


He already has
-Walbro 255
-Custom FMIC with auto water sprayer
-turbo inlet
-SPT intake
-TGV deletes
-Reverse mounted intake manifold(shorter fmic piping)
-EBC
-Catless UP
-bellmouth down (catted? well it was... but he has a tenancy to spit flame)
-2.5" mid
-Prodrive axleback

[BG @ BrenTuning]

Either works, a EJ255 longblock is probably easiest bolt on and go. Plus AVCS down the road.

[vtwrx04]

Looking for suggestions for my new 2012 WRX. My initial thoughts were to just do a divorced catted downpipe with stock exhaust. My reasoning is most of the aftermarket exhaust are loud and expensive for only a gain of maybe 5-10HP. I've considered equal length headers, but again, I'm not sure if its cost effective. My goal is fast spool and maximum torque as opposed to max HP and high rpm. I also need to know if I should buy an Accessport or if you use a different method of tuning. Could you also PM me some pricing for a tune.
Thanks

Can you speak towards reliability of a revtronix chipped 91 legacy ss? It has a front mount, td04, wrx injectors and some 3" exhaust. Also nrand new short block with 12k miles on it. I know the 5 speeds held some good abuse back then. Owner said it made 211/270 before the chip and should be making 240/290 now.

But I don't know enough about them to know if its a time bomb or halfway decent.

Hi Bren! I have a 2011 WRX with a Cobb catted DP and Perrin CBE that you tuned: http://vtboost.com/forums/showthread.php?t=16250&highlight=i8ur911. In the tuning notes you commented that the BPV was weak and leaked at 18 psi and audibly squealed on the dyno. I replaced the oem BPV with a Forge recirculating unit and still heard the leak. I replaced the oem throttle body hose with an AVO silicone hose, hair spray and T-bolt clamps and the leak is finally gone.

Question: Because the engine was tuned with a boost leak that is now fixed do you recommend a touch-up tune immediately for max safety? Also, I'm planning to replace the Perrin axleback with a stock sti axleback and retain the Perrin midpipe. Retune? I've read that the oem mufflers are not very restrictive.

Thanks!

Bren,

Hi Tom,

In the factory tune the AVCS is not optimized and the timing strategy is based around the extra lean fuel delivery at peak torque. By addressing this correctly there is a LARGE gain in power over the whole midrange - something we are quite good at:devil:. With those tunes the boost pressure increases from 14.5-15 to 17.5-18 an overall delta of 3lbs and after 5800 they nearly taper to the same curve +1psi or so. You will notice the top end gains aren't nearly as severe.

Next tune we will show you how our tuning/ignition changes actually make power while leaving the stock boost table as a case study. :D

Meth systems need failsafes, and none of them are perfect. So, if you can't have your meth injection system fail in one way or another without it being a huge problem for you (the car is your only car, daily driver, etc.), you should probably not install one.

Invidia dp
FMS Catback
KS Tech intake
Grimmspeed EWG up with dump tube
Stock vf40

Here's the question. I plan to swap out the turbo at some point which is why I went EWG but as it stands I have the block off plate on the Up. Would it be benificial to install the EWG before a tune with the above listed parts or keep the plate installed untill I go Stage 3?
Anything else in this list you would recommend before a tune on the stock turbo?
I'll be taking the car to you to be tuned.
Thanks for any input!

fuel mileage will go down the pooper!

I disable CL in my car all the time. Usually when I am verifying that my MAF and injector scalars are correct. It's also an odd way for me to tell if I have an unmetered air leak.

I'd love to do a EWG VF40. Sounds like fun. Anything to let it breathe will make more power. But it's your choice to tune twice (with a break given 2nd tune of course). You have all the basics covered - great setup.

When you use a boost leak tester, don't you have to plug off most of the vac lines? Half of the leak checks I see say to do that, and the others make no mention of vac lines at all. :lol:

Yes and no, inlet boost test in small time amounts will show you the leak far before the evap sensor starts howling. :)

Those numbers look good for e85 but the 92 numbers fall way back. Everything Ive seen for a 20g-xt comes in more like the e85 numbers on the dom1.5. What didn't you like about them? Do you think the 8CM 68HTA could get close to 400wtq on a 2011? Synergy 20g?

Bren, whats your feeling on straight water injection on a tune originally not done with water?

Would you see any gains (or losses) with only water injection, no tune? And, is it safe (aside from freezing in the winter)?

Does it matter if the car is MAF based or SD based fueling, how the water injection will react in reguards to AFR?

Also, I assume if you add 50/50 meth/water, the car will run rich without tuning for it, and what issues could that cause?

[Kojak77]

Bren- Do you tune C6 Corvettes?

[BG @ BrenTuning]

Bren, whats your feeling on straight water injection on a tune originally not done with water? Not sure I'd bother since the octane properties of meth make it worth the hassle - pure water not so much.

Would you see any gains (or losses) with only water injection, no tune? And, is it safe (aside from freezing in the winter)? From testing: very little knock suppression on an already good 93 tune.

Does it matter if the car is MAF based or SD based fueling, how the water injection will react in reguards to AFR? Yes it matters.

Also, I assume if you add 50/50 meth/water, the car will run rich without tuning for it, and what issues could that cause? Correct, so you should be tuning for it not just slapping it on. Consult with your current tuner.
