There is nothing wrong with my vf40 but when I go stage 2 in November I want the most I can get out of it. For half the cost of a brand new vf52 he can sell me a vf46 with a custom wheel.

This is what he has said about it. The advantage is that the billet wheel is about half of the weight of the stock cast wheel, so it will spool quicker and then pull harder when it does spool and the combination is very nice and works great with stock fuel system. You can definitely get a higher dyno number with either of those as well as a higher fuel bill every day you drive it LOL but you'll lose at least rpm on spool quickness. Sooner rather than later, your fuel injectors will begin to lose their efficiency from being run on such high duty cycles to try to keep up with the turbo and your fuel pump will be working much harder to keep up, which will shorten the life and require replacement sooner too.

As you know, when these are in good operating shape, even stock, they are pretty darn quick and fun to drive. The custom will enhance that a lot, especially if you're going to Stage 2 with it and you won't be disappointed. Spools up at aboutboost is on before 3k, sometimes sooner depending on what gear the trans is in.

My tires, though they are good, can slip mid-corner when suddenly on-boost before the 5EAT "Nannys" me back into traction. A mph pull can pin me and a passenger to the seats every time, and that's what makes it all worth it. On stiffer suspension, I expect this effect will be a bit more dramatic. I'll keep you posted. Do I want that? Not really. Seriously, on a good day, this car can scare me on an open on-ramp as-is, and I'm probably barely over 12psi on a Stage 2 tune. I haven't looked at the boost levels lately, lol.

It sounds like a great upgrade for me since it will spool faster than a 16g, or vf40 for that matter, and can handle more boost then the vf40 I assume.

I will be bulletproofing my TMIC which I know none of you think is worth anything, but doing so will keep it happy up to 20psi from what I've read of people who are actually using this mod. I don't plan to upgrade the fuel system. I just want a peppy stage 2 daily driver. This sounds like a good ticket. I am ignorant of the performance of the vf Is this general kanene politicale party mp3 download upgrade or more a sidestep?

Used the search and the numerous threads, but didn't quite get the answers i was looking for. As I've now claimed the lib as mine, the tweaks have started and the vf46 is up for a swap. To what I'm not sure hence the question. I see a lot of vf52 upgrades and many happy. Though i suspect that one of the reasons this upgrade is and became so popular is it's relative cheaper price second hand than getting new but also as it's an oem part.

As this will be a new turbo, the price difference is negligible but concerns are about driveability are. Nearly all the threads and opinions all over are based in a manual car. Autos seem to a different pool. Basically, the car is a well looked after specBk, tuned, oil change at every 5 since new. Parts list waiting to go on are PW top mount, invidia dump, 3 port, dw65cc, panel filter and hopefully some sti quads.

Car has been great and reliable.

Or if anyone has other suggestions. I've got a pierburg 3-port waiting to be installed, as well as an intercooler spray kit.

The VF52 probably has a bit of headroom in it at those levels which is good, you don't want to push a turbo too close to its limits. Matt has done the original tune and I very happy. Car drives super well and logs clean. Took a week to want more powaa Just want to up it some Pm coming re meeting up.

Turbo: STi/WRX VF Series Turbocharger breakdown:

Then consider a turbo upgrade. There are limits in the stock systems eg injectors etc so do the research and plan mods within those limits or carry out the required upgrades to support your intended outcome. Subaru FSM, parts, procedures and diagnostics Google this Forum Addicted to corn juice My FrankenStien build thread here: viewtopic. I've not heard of this happening with a stock Lib inlet but its something to consider along with a silicone TB hose.

They are available for stock inlet diameter or bigger turbos. They resist collapsing and smooth the inlet airflow, the latter being the primary reason a tune even on stock is required. Maybe a 3port too? But I'd do the pump and get started tuning first. Yes it would apply - support is a good thing. Support it first for safety and reliability. I'm supporting the stock stuff first then ill consider the bigger upgrades.

There's plenty to gain and yes ultimately the vf52 is a stock turbo with a slightly different design providing a little more top end.

Upgraded Billet Compressor Wheel VF48 Turbo Review!!!

During a 3rd gear pull, Bruce eventually pulled away from me as we reached the rpm range. We were somewhat surprised. Similar supporting mods, my lib is heavier being a wagon In normal driving its all about bottom end, thus I'm not really in the market for this upgrade unless mine fails.

Drive a good Lib for comparison. My lib went from being average and unpredictable to rather awesome. But it took tons of research, diagnosis, repair and modification.
