ok i kno the turbo inlet hose wont make a difference on the stock turbo. but what if it is Ported and Polished?? and would a 3 inch be cool or would the regular diamater be better cuzz 3 inch might increase lag??
(by the way my friend put this on his mazda 6 n said he could hear the turbo spool like crazy. will i get the same results??)
No... it still won't make much of a difference. You need to understand how turbochargers work. They're basically vacuums and air pressure-izers in one.
Let me see if I can explain... imagine taking a deep breath through a small straw. How does it compare to taking one without anything in your mouth? It's harder, right? Takes a longer time to suck in the same amount of air, right? Same goes for turbos. It doesn't really matter what the velocity of the air is in the straw/inlet hose. It's the volume that matters. That's why the best setup (for performance) is to have no inlet hose, no filter or anything at all. No straw. That's why, if you're set on getting an inlet hose, I would recommend getting a 3" one.
There's no reason to get a 3.0" inlet if your turbo only has a 2.4" inlet... If you buy a turbo that has an 8cm inlet then go ahead and get the 3.0" but if you don't, there's no reason to go that big. it's overkill. I disagree that a small turbo will see any gains from this mod though. Larger turbos definitely (which is why they come with 8cm inlets) but not the stocker for sure.
No! You can't use a perrin 3" inlet. Those are only for turbos with 3" inlets. Stock is 2.4". If you get an aluminum inlet (APS or Agency power) it will be 3", but will still fit on the stock turbo with the included 3->2.4" adapter.
Btw the stock inlet has a larger inside diameter in some areas than most silicone inlets. This is why I recommend APS.
Oh god. I would stay away from the APS. I understand it's a wonderful piece and all it's pluses. But it was SUCH a nightmare to install. It took longer to get that thing to to fit in then it did to install the turbo, injectors, and whatnot. And we even had the intake manifold off when we installed it! APS comes with adapters so it can fit stock or 3".
ya c dude that's the problem i heard installation is a bitch. is it something u could do at home?? n that's y i was leaning towards perrin i heard it's easiest to install
It is prone to cracking/breaking including the nipples,it has a very small inner diameter.Any time you free up a restriction before or after the turbo faster spool will result.Same with upgrading the factory TMIC hoses.I'm not going just by Perrin's numbers either.Been tested alot on NASIOC.I use the APS inlet and love it compared to the silicone ones.Comes with a 3"-2.4" adapter for stockish turbos and a 3" for when you step up to the big boys.Takes me 30 min to install/remove.Like mentioned earlier,it's all about moving the PS line!
lol i want to be totally prepared for when i swap my turbo i want to get everything ready i'm only leaving out fuel injectors, rail, n pump untill i get my turbo. The IC is also on my upgrade list too. guess i'm going wit agency power thanks for everything guys
It's not that hard. I recommend you purchase some of those swivel-type extensions, they helped a lot. Take off the power steering pump. If you do that I believe you can slip the pipe on without even loosening the manifold. If not, then you will have to loosen it but you shouldn't have to take it off. It's more work, but imo it's worth it over the flimsy silicone ones..
One of the issues of SubieSport also proved upgrading the inlet hose (with a turbo setup) was effective using a dyno. The connectors on the stock inlet are surprisingly brittle.
Here are pics of my APS turbo inlet. Love it, like others have stated its actually a hard pipe not a silicone one. Its the biggest one on the market so far and is a quality piece. For installation I took off the intake manifold because I had to do my injectors anyway, you can try to squeeze it through but most likely you'll end up scrapping the crap out of it. Good Luck.
I don't know what your mechanical skills are and how patient you are. Changing a intake and installing side skirts is nothing in comparison to installing a turbo inlet, especially the APS one. (Silicone ones you might be able to squeeze through because its bendable) I would have a buddy or two help out and plan the whole day to get it done if your worried. From morning till night. It will be easier to get it on by taking off the intake manifold, some have been able to get it on without removing it, but it seems hard as hell and you would probably scratch it up as I've said.
ok so does anybody know if there will be any fitment issues with the APS turbo inlet hose and the SPT intake?? what sux is the APS is red n the SPT is blue...###
how does the sencor that connects to the new inlet hose connect?
