Vf22

Alright I just ordered a VF22 sti pinks and a fuel pump...

1) Does any one know where i can find some install instructions for this stuff, i wanted to see how hard this install will be.
(could it possibly be worse than an up pipe?)

2)when tuning for this turbo should i start with the TXS utec stage 4 map and parameters and tune from there? How bad would it be to use the stage 4 map with out adjustments to the fuel and timing?

3)What kind of boost should i tune for with this turbo?

4) any ideas on 1/4 mile times and whp #'s?

on the install part of things . . .

The injectors shouldn't be too bad, you could do this in your garage.
When I installed my up/dp I actually pulled the turbo, not that difficult, but most important
IMMEDIATELY after you install the turbo do a coolant flush. THis will eliminate air in the system, otherwise you will have problems, I know this from experience.

And the fuel pump, you should check if you have to drop the rear diff to get to it, I am not sure either way.

Along with whp . . . you should be around 300wph or more depending on the computer management . . . quarter mile . . . approx. 12.##, you should be running in the 12's now.

I hope that helps!!!

later

you can do all those installs at home pretty easy

the hardest part about the injectors is getting the protective covers off from around the rails and them...

the fuel pump is between the the backseat and trunk on the passenger side

the turbo is pretty self explanatory just make sure you prep it before you start driving it and have all new gaskets

You will be safe with 18psi on that turbo...just don't do 18psi everywhere you go

lol what the hell does that mean? Isn't 18 conservative, i mean thats definatly not the sweet spot of that turbo is it? i would think like 20 would be an awesome place to tune to, maybe 21

I was thinking of his engine too...the EJ20 doesn't like doing 20psi all the time..18 psi is safe and still fun...but 20 would work...the gas pedal is the best boost controller

the EJ20 can handle 20psi but not all the time..I have seen the intake manifold separate from the block at 24psi...and I have seen many a Rods/Pistons/blocks destroyed from boosting too high for too long...honestly it is all in how you drive the car..I personally run 19psi daily on 91 oct and 23psi on 105 oct...take into consideration that 19 psi is only hit a rare occasions when playing and 23 psi is only hit rarely when I am racing....then on top of that proper maintance needs to be done

i really think you could run the car all day long on 19...i mean i know that you're with momentum turbos or whatever and im sure that you have plenty of experience but the ej20 is pretty strong and 19 isn't that much boost

You dont think 19 is a lot of boost on 91 octane??

Edit: I think I understand what you meant now....the block itself can handle a lot of pressure but the stock internals can't and the intake manifold will separate from the block under very high boost conditions

No, noone has any idea because noone knows how it will be tuned. Don't take the whole "x number is safe" thing, because you could melt a piston at 18psi or if you get a great tune (either do it with someone who knows how with a wideband or get it dyno'd) you could run 22psi all day long.

PSI doesnt mean much, its really about the state of the tune and the integrity/strength of the motor. Most know that the EJ20 can hold 350whp or so pretty reliably and I doubt that on pump gas -- regardless of what psi you run -- you will be putting down more than that.

So... after everythign is installed right (please make sure you listen to the above post and install everything correctly and PRIME the turbo) get it tuned to a level you and yoru tuner feel comfortable at. If that is only 18psi on pump, or 22psi on pump its up to you as long as you feel ok with the tuner. Ive run 20+ on 91 octane with a good tune for a long time and felt fine about it. As said 1 billion times, the tune is most important... not what psi, what HP or any of that.

well who the hell tunes without a wideband or on a dyno lol

i think with a good tune the wrx will run 20 all day long on 93 which is what we have here in NC

i mean i've been tuning DSMs for a long time now with just SAFC IIs DSMLink so i know what a good tune looks like

i mean i wasn't talking about just turning up the boost lol
