What is this ST tool you speak of? I just lost my TOB again, so I'll be doing this work soon.. For the second time...

No. A 16g is bigger than a vf52. You need at least a fuel pump, and even then you have to taper boost to redline because the injectors are maxed. Also, since you have a 5eat you'll need the valve body mod. I wouldn't say that you should go with a rebuilt 40, as they are unreliable. Why not look at a vf52?

This is exactly why I'm looking at the 16g. I just finished most of the reliability mods to prevent starvation, now I'm looking to do the turbo and my block should be safe for awhile.

I'm in for the 16g, I just have to finish my supporting mods and figure out how to pay for the dang thing without pissing off the fiancee:lol:

No.. You pull the rods, grind everything down, and seal with JB Weld.

For your first question, you should get a tune... I know of people running a 16g without one, but I can't see it being a good idea. Not sure if you'll see an increase in power, but I can say that you won't take advantage of the turbo without one, and I will speculate that it is dangerous to boost without it.

Nice. I'd like to swap out my VF40 (going on 100k mi.) and go to either a 16g or 18g. Probably won't happen for awhile though

Fulton, are you running an 18g or a 16g?

Here's my bug.. 15months and she's already giving me grey hair.

My daughter is 14months, and she does the same thing. She only calls her momma when she needs something/falls down/is hungry. It's fun to ask her to say momma and get a "daddy"

Good to know. What size injectors are suggested with an 18g? I'll probably just do the fuel pump with the turbo, but the injectors will have to wait. I know that I'll want more power down the road, but I can't justify pushing over 300whp until I can afford to swap the tranny. An 18g should be able to get me to a reliable power level w/o going outside the turbine efficiency. Plus, bigger is ALWAYS better, right?

That's kinda what I was thinking. I'm not against upgrading injectors, it just won't be anytime this year... probably next spring.

Is it possible to run an 18g on stock fueling if the tune is mild? Say 18psi? I don't mind a little lag, and I like the idea of giving myself some headroom if I want more power down the road.. which is inevitable. a FP will likely follow the turbo, but I don't plan to swap injectors for awhile. If not, it sounds like the 16g is my best bet.

Subbed... On a fence between a BNR 16g and a VF52. Also lusting at the 18g. The deciding factor is how many additional mods to support the new turbo. The 16g/52 seems like the best option because I can still run stock fueling.

Trying... They were both sedans; one identical to mine, and one that was slammed on rims. Both gorgeous. I just want to meet up with some more owners and figure out what everyone is doing. It's nice to see STI's and such, but I'd like to see more of the same platform.

Understood; I'm planning to swap it out for peace of mind. When I go VF52 I want to make sure that my system can take it without issues. I'd hate to drop the cash on a turbo upgrade then chase failures for the next month or so.. More of a preventative approach. Noted; At what point is the EBCS required? Hence, my question to the OP in the first thread, "did you read the turbo wiki?" There is a TON of useful information there when it comes to questions like these.

I'm planning to bulletproof mine (Thanks BMB) in prep for a vf52. As my car sits right now, I'm pulling roughly 240g/s with a stg 2 tune on a vf40. I know its fairly inaccurate to base hp from g/s, but its the only estimate I have. That said, I should be putting down somewhere close to 270whp. If you're planning a turbo upgrade, you should make sure your engine can handle it by buttoning down all of the failure points through the system. IE the tmic (will leak over 17psi), bpv (may or may not leak at 52 boost levels), fuel pump (so you don't risk running lean by not being able to supply enough fuel). I've also heard the turbo inlet should be swapped out, as well as oil supply lines, and an EBC will help control boost. You can upgrade the turbo without doing these things, but you risk boost leaks, etc, and run the risk of detonation. IMO, its not worth the risk.

Do you have an aftermarket tmic or bpv yet?

My point was just that hp numbers are deceiving.. there may be guys with 40s putting down 52 numbers, but I'm not sure you can expect reliability.. Why push a small turbo so hard when you can push another turbo to the same power level without stressing it?

Fyi.. you're not stage-2 if you have an upgraded turbo..

Why focus on the numbers, then? Why not instead focus on what's needed? You need a tmic if you don't already have one, and you might as well get the fuel pump. You're not going to flow enough through the 40 to utilize the headers or intake. If you're targeting 300whp, a 40 won't get you there. Plus, in order to get close you are pushing more boost than your turbo would like to see.. did you read the turbo wiki thread?
