silicone intakes... YES/NO? what brand should i get?

Hi people

Im pretty sold on the idea of getting a silicone intake pipe for my v7 sti as iv heard the factory one is restrictive and is prone to cracking. im after something robust (none of this collapsing drama)... At the moment im leaning towards the AVO intake, its got wire reinforcing and runs from afm to turbo. good or not? any one had experience with one of these.

If anyone can recommend any would be great... or just lend some good advice >>>>LINKS<<<<<

Im going to install a GFB g-force II EBC at the same time. apparently with intake and EBC i should see some better consistency in my boost levels and hold a higher PSI high end?? and i will get gotasuby to check the tune after installation.

Current mods for reference

- 3"tbe

- DW200 fuel pump

- gotasuby tune

Would a Perrin one be cheaper? http://perrinperformance.com/i-13323994-turbo-inlet-hose-for-2002-07-wrx-2004-15-sti.html

Possibly, i do like the perrin stuff, seems to be good quality,ill look into the price differences. i like the avo because it replaces the afm to intake elbow, extra bang for $$$$.

looks like your sold on the avo its good cause of your reasons stated Tomei make some that are good

Whoops! Missed that extra part. I'd say do it and let us know

I think they work , although I found the biggest gain was from replacing the pipe between the AFM and the under manifold section.

There are some one piece ones around , they go straight from the AFM to the turbo in one piece.

# edit , helps if i read your whole post fiirst , definately go for the AVO 1 piece.

That's the typo Hunter is wanting to get

I picked mine up from STA parts over by auckland airport for about 250 for both under manifold and airbox to under pipe. No issues with collapsing, but yeah these are a c**t to fit

The tomei breaks down to make fitting easier, I'm in the boat that it doesn't need changing till ya upsize ya turbo the pipe in between the afm and under pipe is more effective back to back between 2 V7 sti's mine and a mates he had bugger all gains by going with the full sillicone under pipe and me rolling with the hks intake kit with the standard plastic pipe.

He might have spooled a bit faster (not much) but we put it down to EBC's with his beingn ewer gfb g force 2 and mine being a hks evc4

People make big power in the uk with stock pipes but if i had a big turbo in stock location i would definitely do it. Stock ones break far too easy now theyre 10- years old.

I bought mine from scarles for $250, was a waste of mine it collapsed under boost.

I bought a Samco one from trademe a few years back for $180, luckily for me it hasn't collapsed under boost.. but then again 10psi on a TD04 isn't much.

Unsure of overall quality but there are a bunch on TM for less than anything from Redline or Scarles. thinking of picking one up for myself soon.

god you must have a crappy airfilter . that is a decent vacuum

There was a thread up on nasioc that had some vac pressures at turbo inlet. That combined with a ****ty filter could cause it. Jgm had a youtube vid up showing it as well cant remember what filter that had. **** news cancer got hin he was an asset to 22b.

Minaj was one of those big hks foam types iirc.

cheers guys. Collapsing is something that im concerned about as im running 20psi (falling to 16 at redline) on my vf30... im definitly not going to buy something cheap, think the AVO (if i can find one) or the tomei look the go at the moment. Hopefully with a good intake pipe and GFB EBC ill be able to hold that 20 all the way.... then my engine is maxxed (on safe tune...)

I dont think ill install it myself as iv heard its a damn right *****, so i think ill just pay and get a expert to install it.

Here's some pics of the M&H pipe through STA parts, about $130 delivered with CS discount. 4-5 nomax layers and a very solid pipe. Pic's courtesy of ADIKT on page 6 of my single turbo conversion thread:

i bought a cheap trademe one for my last build and it never had any issues.. didnt have a brand on it and just bought another cheap one hopefully this one doesnt colapse

+1 for the m&h ones from sta, was running ~220kw at the wheels @23psi boost on a tuned v7 with vf30

obviously no issues with collapsing then? that all im worried about! you use a EBC to get it to that psi? M&H ones sound great value!

I am running 23 psi on the stock v8 STI inlet without issues. Also I know so many people running that kind of boost levels for years on the stock inlet without any issues. I wouldn't underestimate them.

holding 23psi to redline?

Na, 23 psi mid range and 17 psi up top on VF37
