Carlton603 Posted March 14, 2016 Share Posted March 14, 2016 Hi all, My OEM turbo inlet is torn and has accumulated a fair amount of oily residue where it meets the compressor. The local dealership quoted $138 for an OEM replacement, and I have found Mishimoto inlets for around $190. My car has a stock VF40, with stage 2 mods and tuned by Granite State Dyno. I will be replacing this on my own soon, but have a question. Is there any "real" benefit to the Mishimoto (or other aftermarket inlets) or should I just stay with OEM? My gut says OEM, what do you think? Cheers! Link to comment Share on other sites More sharing options...
Max Capacity Posted March 14, 2016 Share Posted March 14, 2016 I went with OEM. Check on line pricing from one of the dealer vendor here. It was in May 2012, I think I paid like $90. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.

seanyb505 Posted March 14, 2016 Share Posted March 14, 2016 General consensus here is stay with OEM for stage 2. I paid 96 shipped last month. Link to comment Share on other sites More sharing options...
Carlton603 Posted March 15, 2016 Author Share Posted March 15, 2016 Thanks for confirming, I was leaning towards an OEM inlet so it is good to know I was on the right track. I found one for $98 shipped to NH, I'll be ordering soon. Can't wait to see how much fun it will be to install Link to comment Share on other sites More sharing options...
baconbits Posted March 15, 2016 Share Posted March 15, 2016 If you stray from OEM (all it does is more boost noises), get the AVO for the 05-06 cars and *not* the Perrin. My Perrin one is probably 1/2" too long on the turbo side which makes everything up front a bit more difficult. The worst bit is that the BPV connection spigot is 2-3" further forward which is how the 07-09 Legacies and the 08-14 WRX are, but Perrin lists it as fitting 05-06 Legacies too. It does but not well. Getting the old one out is by far much more difficult than getting the new one in, at least when it came to my particular install. Some people fight for hours trying to get it on the turbo with 17 screw drivers and picks... I didn't need any tools and it took not even 5 minutes all 7 times I needed to pull it off because I forgot clamps or to connect PCV hoses or whatnot. The silicone inlets are much stiffer which makes twisting and aiming them much easier to get it over the lip on the turbo. Link to comment Share on other sites More sharing options...
fahr_side Posted March 15, 2016 Share Posted March 15, 2016 I keep reading it's not possible to install an OEM inlet with the manifold in place. Anyone actually done that? Obligatory '[URL="http://legacygt.com/forums/showthread.php/2008-gh8-238668.html?t=238668"]build thread[/URL]' Increased capacity to 2.7 liters, still turbo, but no longer need spark plugs.

Hirschman Posted March 15, 2016 Share Posted March 15, 2016 I keep reading it's not possible to install an OEM inlet with the manifold in place. Anyone actually done that? I R&R'd mine with the manifold in place. I did have the turbo off at the time, so that may have made it easier although I don't see any reason why the manifold needs to come off. I was swapping a stock intake for a stock intake by the way. Link to comment Share on other sites More sharing options...
Max Capacity Posted March 15, 2016 Share Posted March 15, 2016 From what I've heard about installing the others it's still might be easier to raise the manifold at the TGV's to head or TGV's to intake. I think total hours to do the job may about the same ? I have lifted the intake to replace the O-rings in the car and then removed the whole intake at the TGV's to head for the short block. Granted that was on the engine stand, but once you bite the bullet to do this job, and decide what your going to remove, buy the new gaskets... Can you lift the manifold enough with the fuel lines attached ? They are not that hard to remove from the shock tower. Disconnect the big electrical connector Disconnect the turbo cooling tank hoses some vacuum lines, may be ? Can you lift the manifold enough to slide it out ? May lay the PS pump to the side ? May be BMB or covertrussian will chime in soon ? 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.

Lafta Posted March 15, 2016 Share Posted March 15, 2016 This turbo inlet.....Is it a part that wears in time, and needs to be replaced, and or are there other factors at play which necessitate replacement earlier? Or? thanks! Link to comment Share on other sites More sharing options...

I do love more boost noises, but can't justify spending another $150 if I don't have to. I keep reading it's not possible to install an OEM inlet with the manifold in place. Anyone actually done that? I searched a lot before posting, and this seemed to be the most informative "How To" (http://legacygt.com/forums/showthread.php/install-avo-turbo-inlet-hose-204330.html) and it suggests removing the 8 IM bolts so it can be lifted but not full removed from the engine. I will try my best to document my install in case it can be of help to others. Another question, should I be replacing the IM gaskets if I end up removing the bolts and lifting it/moving it around?

Or? thanks! In some cases yes, the heat and the oil vapors attack the rubber flex section at the turbo inlet. I'm thinking your ok for awhile yet, if your turbo ever needs replacing, than may be think about the inlet. When I replaced my turbo at 142,000 miles I put a small cut in the end of the hose trying to line up the turbo. That's when I figured out to bolt the turbo to the up pipe. I replaced the inlet 12,000 miles later when I did the short block. You should just go back to skiing and not to worry so much LOL 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD).

Yes, replace any gaskets you loosen, its cheaper then having to go back in later because the $10 gasket leaks. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs.

I am not sure if it is considered a "wear item", however, they are known to get covered in oil which causes the rubber to soften. Combine that with heat from the turbo and they can develop tears, which is where mine is at the moment. Try to visually inspect where the inlet meets your compressor, and see if there is a bunch of oily residue built up in that area. May give you an indication of the condition of your inlet.

freddy31 Posted March 16, 2016 Share Posted March 16, 2016 I did a misimoto a few months back. Pulling the intake was a pain but made it easier to install. It's large so you have to watch putting everything back together hoses get tight and I had to re-route a little. I hope it outlasts the stock and it does sound good.
