You are right the 34 will come on later and make more power. There does not seem to be a huge market for the VF35, due to the VF34 being so popular. I think people dont even take this turbo into consideration when thinking of upgrading. The 34 is bigger, but the 35 still packs a good punch.

It is a good turbo and will cost less than the 34, purely for popularity reasons. Its a great street turbo IMO. I have attached a LINK to my thread from the Verso tune. The dyno charts from the stock STI dyno run & overlay of the Verso tune done. The stock run was at 1.2 ish bar, after the tune it was @ 1.6 bar.

You can see it comes on hard and fast and has great low - mid range grunt but dies off at the top end. This is exactly how it felt to drive. You were needing to change gears at about 6500 rpm, as from about 6000 onwards you could feel the pull drop off. This was at the drags of course

The VF34 would move the chart lines to the right a bit & it would get you another 45 ish hp running the 1.6 bar boost pressure.

The VF35 is just a idea I threw out there, as not many people think of it. I am not talking it up, I am just stating the facts, that it is a good, low cost turbo for an upgrade to a WRX.

Is THIS not a TMIC on the Vortex?

^ now i regret not buying your 35 you sold yours for $370, sounds very cheap or is that what they are worth?

also the 34 is ball bearing where the 35 is not im sure when reading the turbo sticky?

I guess they are only worth, what someone is willing to pay. I still think you will be able to pick one up much less than a 34. That is if both turbos are in identical condition of course.

There was a 35 on another site only a few days ago. They were asking $700 for it, but it had only done 15,000ks or something. Its sold now, not sure what he ended up getting for it.

35 has thrust bearings and 34 is ball bearing. The 34 is without a doubt better than the 35. But people seem to overlook the 35, its still a good low - mid range turbo.

Better stop blabbering on now in this guys thread....

Cool, thx for the info. Well this is going to be my first turbo engine and i don't really want to go with cams, mods $1000 turbo's, 1.6 bars of boost, Power FC, etc and all this really great but expensive gear.

What i really wanted is just above normal, maybe a slightly bigger turbo, better ECU like if possible a plug and play STI one. I definitely don't want to blow the engine.

FMIC basically because i also don't think a top mount will fit under the bonnet.

5. CAI, goes without saying really

6. Boost controller. This is a must for low end pull, with any turbo you choose.

8. Higher rating (opening pressure) waste gate actuator. HKS have a 1 bar one that would suit you I think.
Could you explain to me what is a TBE and CAI?

Without going with all the good mods you suggested and staying pretty much stock, is a boost controller and a higher rating waste gate actuator necessary?

Would a cat less 3inch dump pipe be a good idea for me?

Oh so CAI is basically a pod filter and the end of a pipe that replaces the factory air box and is place somewhere where it gets cold air?

Thought of using a WAIC off an RS? Don't you have one laying around the place?
Would be about as efficient as a stock TMIC without the lag of the FMIC.
