Default aftermarket turbo inlet hose, solid intake elbow, intake... will something break?

will be running an ARC air induction box, zerosports intake elbow, perrin turbo inlet hose... basically replacing everything that had an accordion on it. with everything being rigid with no flex... will something go bad/break?

The Perrin inlet hose that I have is silicone....and IIRC the Zerosports piece has a silicone piece included in it somewhere...
SO....I don't think you'll have a problem....unless it's your wallet being real thin after buying all this stuff...

well... my zerosports elbow has only the w silicone hose connectors but there is still hard contact between the pipe openings... my arc is in transit to azscoobie for dyno testing... i'm shopping around for an inlet hose and was looking at a used perrin.

who makes the best inlet hose? sti? perrin? samco? prodrive? turboxs? does it matter?

You could get an MRT or AVO(they are identical) and not use the Zerosports at all...
The above are one piece units which replace the elbow as well as the rest of the inlet.
I, personally, would prefer this option.
There should be no 'hard contact' between any of the elbow pieces when everything is installed correctly.

AVO was a bitch to install. I think mine may have been molded wrong 'cause I had to cut the nipple for the PCV off the AVO hose and move it where it wouldn't rub against the intake runners (drilled a new hole and used some epoxy to hold the plastic nipple). If you use a regular hose clamp on the turbo side of the hose, make sure you fold the end over with your screw driver after you tighten the clamp. Mine kept loosening up and the hose almost slipped off the housing on several occasions. BUT.. it's a much smoother path for the air to travel and if you already have a free flowing intake system (Rampod Unifilter or something to that order) you'll notice a "smoother" sound during spool up. I love it and I'd recommend the AVO/MRT style.. hopefully no one will have the problems I did.

what about the intercooler hoses? are they as important as the inlet hose in terms of airflow/vaccum/etc? can't afford to buy everything at once... going at it a little bit at a time.

I don't know about the other aftermarket TMICs.. but the Hyperflow came with new silicone hoses. So if you plan on dropping the grand for a different intercooler.. it MIGHT come with them. The intercooler hoses might be considered MORE important since they'll suffer from positive and negative pressures. Personally I don't think any of these hoses are too important unless you're running higher than stock boost or you're digging for every last bit of bolt on power. Some write these upgrades off as preventative maintainence..

Maybe you should wait until you have enough loot to buy ALL of the hoses.. I'm 99% sure you've gotta remove the IC to install the intake hoses.. and of course you need to remove it to install the IC hoses. I remember the chicken little's screaming how important it is to change the intercooler hoses 'cause they'll leak or crack, but I don't recall hearing any actual failures.

Try finding them used, too. There's gotta be guys who went from TMIC to FMIC who are selling some silicon IC hoses.

The only thing I noticed about running silicon hoses is it's much harder to get parts on and off, there's no accordion to flex in the I/C hoses, or the intake hose (goes from the airbox to the inlet pipe.), this last one making it a royay battle anytime I have to do anything that requires moving the airbox...

I haven't heard of either.. but everyone still says it CAN happen! Do YOU want to be the one stock on the side of the road with no tools and a broken car!?! I'll bet your answer is "no", so you should invest in some expensive silicone hoses!

I doubt the plastic hoses would collapse or blow off due to vacuum or boost.. the silicone would be just as likely to blow off, too.

I have ripped my turbo inlet and a few others numerous times. Its a piece of crap and not flexable at all.

I have also blown it own numerous times with high boost pressure.

This has happened to MANY MANY people.

The stock inlet hose is not made to handle high HP apps and high boost.

BT: You will be fine. Nothing will break at all.

Finally some testimonials reassuring my suspicions that I did NOT waste money on expensive intake and IC hoses.
