Turbo inlet, which one should I get?


Recommended Posts

I need to replace mine asap regardless of the best reccomendation. I had a turbo coolant leak so the plastic looks beat up and while changing the Purge Valve I found out one of the vacuum lines to the inlet was already broken, but taped over. It's been that way for years

 

I was thinking of the Mishimoto one because of the metal nipples on for vacuum lines and what not. Is that one better? Should I just go with my original choice of Perrin?

 

Lastly, is this relatively easy to self install? I have to go to a Subaru shop anyways to add saggy butt spacers in the beginning of June, but could always push forward my appointment.

 

Lastly, thanks in advance to everyone who comments.

I went with the perrin simply because I got a deal on it at the time. Like with any slightly larger inlet, its a pain to get it installed. On the perrin, the bpv hose nipple is slightly off since the hose is made for the 08+ wrx, and the 05( I think 06 too) GT have it a little different, which I solved by getting a venair bpv silicone hose. If you dont care about having aftermarket stuff, and want an easier install, just go with OEM, having cool aftermarket stuff is neat, but having a vehicle up and running with minimal downtime is cooler :cool:

That's what I'm thinking. I'll be calling and going to the dealer tomorrow.

Is this thing a nightmare to install from what I've heard?

 

I'm going to install my new intercooler next weekend and I already figure this is going to be easier with that off.

Its not a nightmare per se, but it definitely feels more difficult than a plastic tube should be to wedge in there, also depends on how big your hands are. Definitely IC off is necessary, for the bpv hose an pcv valve hose at least.

Installing an intercooler is child's play compared to to turbo inlet. You are in for a fight. You might want to get an ancillary hose kit and replace as many coolant and vacuum lines as you can stomach.

 

I bought a cheap silicone inlet for a wrx off eBay for 50 bucks, and it has metal nipples (not really a big deal imo) and it works fine with a little creative vacuum routing. Wasn't a big deal as I got the complete hose kit from the guy in Washington on the boards here.

 

If you want fast and easy, just go oem, if you want cheap and taking care of other issues while you're toiling in the engine bay, do what I did

Sounds like this is a bit of a challenge. I look forward to it. I should be fine hand size wise. I changed the purge valve down there and only took off the alternator cover.

 

Anything else I should know or be aware of?

I went with OEM and had the intake manifold off when I replaced mine during the engine rebuild.

 

Look at lifting the intake from the Heads. While your there tighten the car line clamps under it. They can leak in cold temps.

 

Get new gaskets for the TGV's to heads, have the black o-rings at the intake to TGV's been replaced with the new larger orange ones ?

The inlet is a F-ing PITA :lol; do yourself a favor go to the parts store and buy some 1/8 and 1/4 inche hose (4 feet of each) and the T and I barbed fittings and the worm clamps. If you dont want to touch the IM you may want to extend some of the lines for your own sanity. ON my LGT the BPV hose was the worst!

 

Mark the hoses with a paint pen or similar to keep track of them, I lost one line in the process of installation under the inlet caused me to over boost, traced it from the cold side and found it loose under the inlet. I extended all the lines by 6 or 12 inches for the next time around the BPV you will have to put the inlet in half way get the hose on tighten the clamp then push it on the turbo, make sure you have a pick set or at least a 90 deg one to fit the rubber lip onto the turbo this requires you to push the inlet while working the lip VERY VERY ANNOYING :lol: Some folks mix up soap and water and spray the inlet to ease this process, spray the tubro and inlet the water dries.

 

Took me 4.5 hrs to do this and only 93 minutes to change the clutch!

I don't get why everyone has so much trouble with these, it was fairly easy for me, heck I even retrofitted an STi Perrin inlet, and still wasn't that bad.

 

So much room I could sleep there, but seriously LGT's have much more room then STI's do, I could fairly easily stick in a 3" pipe.

We can't all be badasses Covert. That said the Perrin inlet took me about 4 hours to install, mostly due to me trying to reuse the Subaru clamps with the wrong tool. With the right tool... Maybe 2.5hrs start to finish for a shade tree mechanic.

I would think that removing the PS pump and laying to the side would help, may be the alternator too.

Took me an hour and half to get the engine out, seriously probably took me two+ hours to get the inlet out. All those clamps and wire connections underneath are terrible to get to. Not to mention, if you need the car same day, buy extra breather and vacuum lines. The rubber turns to hard plastic over time with the combination of oil and heat. One of the rubber breather lines snapped right in half when I tried to remove it.

I also seem to recall it didn't take to long to remove the intake manifold when I pulled my engine out.

 

I seem to recall, the turbo coolant tank comes off, the big electrical connector on the right shock tower, the fuel lines from the left shock tower, tmic, ground wires on the ground bar by the back of the left head, then the bolts at the TGV's to heads. (trying to recall how those grounds are routed, may be then can stay on)

 

Then lift the whole intake assembly.

Sitting here I'm debating whether it would just be easier to pull the intake manifold? I've done NA Subaru manifolds and they aren't terrible as long as you just disconnect the big engine wiring harness vs all of the little connections. Of course, it's really easy to miss one coolant line...

Man, all of the other posts almost make this look too scary to attempt. I got the new OEM inlet today and I like the tip on how to get it on the turbo with a 90° tool. I'll keep that in mind.

I'll also start early with a fresh pot of coffee just in case I have to take a short walk to the parts store.

Soaring, how'd it go?

I'm in the middle of doing the Perrin inlet and a billet turbo install. I'm just waiting for a new oil line kit to arrive before I finish the job.

My inlet was in very good condition, I thought it was cracked but it was just some flap that positions the worm clamp for the turbo side...

I knew that removing the IM was the right way to go, so I did:-)

SPeC.B_MaZTer, I got as far as I could from the front by the airbox. So, not really far and I'm figuring that what you did is easiest. I'm going into a subaru specialist in June, I'll just have them do it. I know what is and isn't in my reach.

I can't get to the three connections closest to the turbo. The clamp for the BOV isn't facing up like I expected. Nothing I have can get to it. I did find another vacuum/air leak with this thing. Is it direction specific? It's on two short hose lines above the purge valve and behind the alternator.

I'm only bumping to have found out this is the filter for the Manifold Ambient Pressure sensor and can also get clogged and worn out. I put in new hoses for it since one became so brittle it cracked in half. Time for another trip to the dealer on Monday.

Yeah that sounds about right. :spin: Mine dry rotted i replaced it, did not see any arrows on the unit, did you have hose on hand? small worm clamps?
