pdXammo Posted October 19, 2019 Share Posted October 19, 2019 Here are pics of what I have for breathing on my new project. I hear the stock setup is actually quite good but, I haven't got those pieces to work with. With what you are seeing here how would you proceed? I likely will end up in a stage 2ish build and looking at a vf52. Link to comment Share on other sites More sharing options...
pdXammo Posted October 19, 2019 Author Share Posted October 19, 2019 I was thinking the grimspeed CAI, It seems to be well thought out and received. Link to comment Share on other sites More sharing options...
pdXammo Posted October 19, 2019 Author Share Posted October 19, 2019 Also, what is that little black device above the inlet in the second pic? Is that the stock TMIC? Link to comment Share on other sites More sharing options...
awfulwaffle Posted October 19, 2019 Share Posted October 19, 2019 (edited) I would leave all of that alone and spend your money elsewhere. That's a fine intake for stage 2, and I don't think anyone here will tell you that a GS CAI will be dramatically better than the K&N you have on there unless you're going for more power. . The little black device in your second shot is a 3-port electronic boost control solenoid (EBCS). The stock TMIC is what you have in your 3rd picture. That is worth upgrading depending on how much boost you intend to run. Plenty of people run the stockers with stage 2, though. They just tend to start leaking at the joint between the side tanks and core if you run too much boost, but that area can be reinforced. Look up the 'bulletproof stock TMIC' threads.

shralp Posted October 20, 2019 Share Posted October 20, 2019 Stock intake is totally fine for a VF-52, (and in fact you can start inviting boost creep with an aftermarket CAI until you bump up to a bigger turbo). Best to get a dyno tune at some point to ensure that the tune can be scaled to a non stock intake. I'd also suggest spending your money elsewhere at this point Link to comment Share on other sites More sharing options...
Nonamedude Posted October 20, 2019 Share Posted October 20, 2019 Yep better tmic or at least the bulletproof mod. I think leaks are common around 17+ psi. That intake is fine though save the money and put it into the intercooler or tune. I'm assuming it's tuned right now? Did you just get the vehicle? Cobb AP? If it's not you need a tune with aftermarket ebcs has been my understanding. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...

I am doing some minor things then running it to a shop for a full diagnostic. If it's in good health I'll add some things and get it tuned. If not I'll start righ away on a 257 Link to comment Share on other sites More sharing options...
Tehnation Posted October 21, 2019 Share Posted October 21, 2019 (edited) leakdown and compression test are a must! Yea judging from the setup, whoever owned it didn't know much. They shoulda bought a tmic before an intake. For stage 2, 1 or anything, you should get an uncatted uppipe and 3" downpipe with 3" to 2.5" adapter if you want to keep stock exhaust, then an aftermarket tmic. all that stuff is useless(intake, tmic and vf52) without the 3" downpipe, thats step one!

Tehnation Posted October 21, 2019 Share Posted October 21, 2019 take a picture of the downpipe, so we can check if its aftermarket or stock! And take a picture of the uppipe so we can check if the previous owner swapped out the catted uppipe, if its stock uppipe that shit needs to go in the trash immediately! the catted up pipes will discharge shrapnel into your turbo and then into ur engine which will KO everything!

Tehnation Posted October 21, 2019 Share Posted October 21, 2019 (edited) If you have some $$$$ get the Grimmspeed tmic! your intake is already aftermarket cai so there is no point buying another. Also check up and research what people are saying about that perrin turbo inlet pipe, here or on nasioc, because there have been issues with soft/silicone ones collapsing in on themselves under vacuum, so only a handful of turbo inlet pipes are actually "good".

Tehnation Posted October 21, 2019 Share Posted October 21, 2019 (edited) don't worry , we'll set you straight! Also look into getting a fuel pump, i recommend the aem 50-1215. Edited October 21, 2019 by Tehnation Link to comment Share on other sites More sharing options...
boxkita Posted October 21, 2019 Share Posted October 21, 2019 Not a Honda. Intake is the last thing to upgrade not first. Finding a good tuner is worth more than any stack of parts. Build my car Boxkita Track days Link to comment Share on other sites More sharing options...

I thought that wasn't until like 20+psi that anything had those issues? The new perrin are mesh reinforced so you might be able to squeeze it some. If not you can always do some cheap mods to resolve that issue if worried. Not sure it'll be a problem on a vf52, not until after upgrading fueling at least.

Tehnation Posted October 21, 2019 Share Posted October 21, 2019 Your probably right, but then again vf52's or any stock 2.5 turbo can push 20+ psi on right setups. Link to comment Share on other sites More sharing options...
Nonamedude Posted October 21, 2019 Share Posted October 21, 2019 Fair enough. I'm armchairing it honestly. Mine doesn't even run and I've got no experiencing. Just soaking in info. It's certainly worth checking into but you're heading the right direction. And like boxkita said, find a good tuner. And certainly get a leak down and compression test. I wish I had, might have saved me $1k in towing from Kansas to Utah. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...

Finding a good tuner is worth more than any stack of parts. very true! basic setups can be done by an etune i'm assuming. But intakes sometimes make things wonky as well as bigger fueling if not done in person/ on dyno. But etuners have come a long way. Any good dyno tuners in Washington?

After 15years + , folklore still drives builds. I spent the weekend with a 400hp sti using a Perrin intake. I didn't see it collapse. There's other stuff that fails, most of it cheap knockoffs. Quality goods well maintained fail only under extreme circumstances. "I heard" or "I read it on FB" generally originate from someone who hasn't a clue.

boxkita Posted October 21, 2019 Share Posted October 21, 2019 Several local tuners exist. Spending the money is usually the problem. Bringing a stack of random parts and asking for a miracle is usually where things start to have issues. Build my car Boxkita Track days Link to comment Share on other sites More sharing options...
pdXammo Posted October 21, 2019 Author Share Posted October 21, 2019 Great advice guys! picked up some injectors and a rebuilt vf52 from another semi-local member today. Also grabbed some Work wheels. I'll get the testing done this week and see how deep this rabbit hole goes, Link to comment Share on other sites More sharing options...
Tehnation Posted October 21, 2019 Share Posted October 21, 2019 I just think its better to know the situation of your parts before moving ahead. I see a red flag when someone puts on a silicone turbo inlet on a stock turbo, brand wasn't the issue, there was no need for it, or the intake, so I would question everything. The op didn't buy all this stuff, it came with the car I'm assuming. All I can say is research needs to be done, otherwise he wouldn't make a post about getting another intake, when he already has a k&n short ram intake. Thats an old design, and i don't know anything about perrin so i'm assuming thats an old design as well, it is an 05. Its better to know exactly what you have.

Tehnation Posted October 21, 2019 Share Posted October 21, 2019 what size injectors? are you considering running e85? Link to comment Share on other sites More sharing options...
pdXammo Posted October 22, 2019 Author Share Posted October 22, 2019 I don't know if I've ever seen e85 sold, never looked either though... Have some id750 topfeeds from another member. last unresearched buy but, I think it was a sound one. Link to comment Share on other sites More sharing options...
shralp Posted October 22, 2019 Share Posted October 22, 2019 The 750’s should be fine as long as they are within spec for flow and will allow you to max the potential of the VF52 when paired with a better fuel pump, (of course you’ll need to swap to top feed fuel rails now) Link to comment Share on other sites More sharing options...
pdXammo Posted October 22, 2019 Author Share Posted October 22, 2019 I got them from another member who stated low mileage so they aught to be good. He referenced having them cleaned which I will. He talked about an adapter, was he meaning change rails? I'd be inclined to go new rails than adapter if this is the case. I've got a thread going about this engine which has become a tire discussion lol but, you have some ideas about fuel rails and fuel pump? Link to comment Share on other sites More sharing options...

On fuel rails I've seen suggested running to the junkyard and getting oe ones from an 08-09 lgt or certain year sti. Don't remember the year. You'll also need top feed tgv. There were some for sale in the forums, or the aforementioned junkyard. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
