Default Vf22?

Yes, I have done the search. I have done the search many times. You should try doing a search on this to get an intelligible answer. The search is your friend. The search loves you. Kill the search! I mean, give it the shocka! No, um, anyway...


OK folks rather than ask about just a turbo, I'll ask about a package of parts.

For my 06 FXT, I'm in the same boat with the 06 WRX guys not 100% knowing what size injectors we have (it is believed they are 550cc). I'm equipped with the following right now: TurboXS stealthback with cat, STi axleback, AP on stage 2.

Looking to add: VF22 or other turbo, large TMIC (like TurboXS or Helix, for example - I want larger than the STi TMIC), Walbro 255 pump, and a Protune for pump gas and race gas.

What I'm trying to do is simply get into the 12s in the quarter mile on pump gas and hopefully mid 12s on race gas. I'm looking for opinions here in TX since the experience base with the weather will be a factor. Is this feasible?

I'm also not 100% sure which way to go on the turbo and the amount of boost to run. A lot of the vendors are pointing me to at least a VF22 for a turbo and either a FP green or TD06. I'm guessing this would also mean bigger injectors. But then there are guys like HK Phooey running a VF30 and ripping well into the 12s with a "too small turbo" on his wagon.

Advice and opinions welcome. And I really did a search but the advice was never backed up with any results that I could find - seemed like a whole lot of opinion.

Thanks in advance.

Skip the vf22. It's cheap for a reason. The same reason vendors are trying to sell it to you. They are trying to get rid of them because nobody buys them. There are some people on this board that have them and like them...it's not a bad turbo...there is just much better out there right now.
I recently did a tune on a vf 22 equipped car and it was real nice, but he spent like $600 in mods to it like wheel clipping, coatings and p&p. For the money he spent, an 18G would have been a better choice on a 2.0L. If you want 12's in a FXT I would say the 20G or Green are the best choices. External wastegate is also something I believe in...you can recirculate the dump if you want, but I like to atmosphere vent them. A big top mount is a must( I prefer not to cut the bumper for a FMIC, but that's just me) and water/alcohol injection will make it really nice. 650's should be enough injector, but if it's the same price, go a little bigger in case you want to go bigger on the HP in the future.

TD05-16(or 18)g or vf34...

the 22 barely makes any more power than either of those two, and has much worse spool up...

as far as injectors, no clue...

You need a catless uppipe, and I would junk the STi axleback for a better flowing one... it makes a lot bigger difference than you think, especially with a bigger turbo and a tune...

hope this helps...

Whoa..I missed that mod...Danz right. That thing is a bottle neck. I saw that in person on the Dyno. This guy picked up 25ish whp after swapping his exhaust at the axle back to a Nurspec or something. He had a 3" turboback on his STi fitted w/a stock sti axleback. ( Not that I recommend the Nurspec..I had one...toooo loud for a daily driver, but you get the idea)

i know you probably dont want to introduce another turbo, but what about a ej5-40t. the thing would have virtually zero lag on a 2.5 block and it supposedly flows the same, if not a bit more than a 16g. that should get you into 12's fo sho.

It is a great budget turbo...but I think there are better options out there for his application.

That's a pretty nice unit on 2.0L...not much lag at all.
I've never seen one on a 2.5, although I bet it would be a good combo.

i run a 22 and im debating whether or not to run NOS in the low end to spool the turbo. i would get a 34 if i were to start from scratch. ball bearing > sleeve bearing

Not true, I absolutely want to see everything out there. The 40t looks like a very good turbo and is reasonably priced for the CFM (580). Thanks for hte heads up - as the title implies, I'm new to the Sub crowd but have been around other makes for a while and certain two-wheeled varieties.

I have a used wet kit if you decide to go that way.

VF22s are without a doubt the best IHI has to offer. They may be older technology, but means nothing when it comes to actual real world performance.

Ignore what these people are saying abotu bad spool, they simply have never seen one set up properly. My 2.0 WRX with a VF22 hit 14 PSI by 3k and 21 PSI by 3500, and thats not that uncommon. The 22 has a larger exh housing than the 34/39 which is a VERY good thing on the subaru motor. Due to this, it carries more boost to redline than a 34 or 39, which means more power at the top end where subaru motors desperately lack it.


Not to mention that since you have a forester, you have a 2.5l motor. The VF22 is the smallest turbo that I would consider putting on a 2.5. I am only running the stock 39 on my STI because I dont have the money for a 20G right now. Even a TDo5/16G is really not enough for these motors, you should be looking more at TD06/18Gs for a worthwhile upgrade.

Honestly the problem with your car isnt the 22. Its the setup/tune. There is no reason anyone needs assistance to spool a 22 if its set up correctly.
The difference in spool between a well set up 22 and a well set up 34 is about 100rpm.

You want a spoon to stir that up with, Danz?

There was only one guy complaining about the spool of a 22 in this thread.
It's just a matter of personal preference, I guess. Like I said the 22 is not a bad turbo for the price. I just think the 18G, 20G and Green are better choices for a 2.5. The 22 'fits' in the car better than the FP units, but that is about the only place where I would say it excels over them. The 22 is much laggier to full boost than a 34 on a 2.0L, regardless of who tunes it....but we are talking 2.5 here so that really doesn't apply...and I'm not in the mood to argue.
Even Davenow agrees that the 20G is a better unit for the 2.5, or he would be saving up for another 22, wouldn't he?

i was just messin' with dave... since he's a yankee and all...

from what i've read, the 16-20g are all good turbos for the 2.5 as long as you go with the td06... supposedly the 05 is more prone to compressor surge...

but iirc if you go with a td06, you need new injectors...

From what Jarrad told me, new injectors aren't required with a TD06-18G. 20G and larger, yes. My $.02.

Odd... i think you would be running too much turbo then... because a td05-16g can't run to it's capabilities on stock injectors, but it isn't too far beyond... I don't see how a 18g wouldn't be way beyond maxing out the injectors...

The 18G would work w/ 650s, but they would be maxed out at around 21 psi...If you wanted a race gas or alcohol map w/ more boost, the injectors would be too small...in my opinion.
