no it wont

its not that important ( unless u start getting into serious boost levels )
the main reason pipes pop out of silicone joiners is because of pressure build up in tight angles and poorly made and poorly fitting pipes
u normally see it happen when u have a 90 degree silicone joiner coming right of the compressor housing because thats where most of the pressure will collect causing the silicone joiner to come of the compressor housing
in this case he has a 3 bolt flange bolted to his compressor housing and then a silicone joiner i highly doubt his going to pop his intercooler pipe apart from his silicone joiner

Im wondering if one the Hypergear Hi Flow T25's would be the way to go for my situation? seeing as my car is only a daily/streeter anyways plus cheaper and less messing about but with those , though if I would still need to upgrade injectors and ECU with a High Flow T25 then ultimately Im better off just going T28..

do this... no more loose bolts... ever Posted Image

Haha, love it. Tracking it on a rainy day would suck though. Considered welding a 90 degree bend to the tip and expanding the cutout to suit?

nah i havnt had it on the track like this yet. will be awesome to see its massive flames comin out though i cant wait. even if its pissin down on track day im not worried cause that piece of exhaust will be well in excess of 500 degrees celcius so water wont nearly reach the turbo. it will just steam up plus the exhaust is constantly blowing out there remember ;) if the windscreen gets too much shit on it (doesnt blow smoke so it shouldnt) ill just extend it up to roof height :)
i even have made a little cap for it for when it is parked in the rain... sounds awesome on my 8400rpm rev limit but!!!!

i used gktech braided lines as well they are awesome worth there weight in gold.

definately get it dyno'd in the near future cause you will run a bit too lean coming onto hard boost.

i reckon mine is just a touch more laggy but definately much more powerful all the way up to rev limit but mines a ca so compared to the sr i guess i would feel the lag more due to less torque from the motor.

some pics of my install (its a ca remember but shouldnt be that different)
after manifold install had this issue

i run 19psi and it hasnt come off yet so just cut the oil drain like i did

now another problem i faced on the ca is woth the standard turbo the wastegate pressure line is on the turbo itself. i didnt want to drill and tap the s15 turbo so using the BOV provision on my intercooler plumbing i done this and it works a treat

...and yet it happened to me. :(

You are however right in saying that a pop-off isn't guaranteed. I probably should have stated it 'was a possibility', as my pipe setup is a little different to factory.

All said, we don't know how good the final pipe setup will be, and a bead is good insurance. Something as simple as a mild flare using some vice grips works, and was my side-of-the-road solution.
Not like it costs anything, or takes special skills to add a small lip.

Ive emailed about and theres a Turbo mob over here in W.A who suggested a GT25 Turbo ,they are new units but cost $1200.00 not inc Gst!.

Ive looked a pics of this and other Turbo's and want to know this= on my Stock T25 Turbo and on the T28's the intake Snout prodtrudes right out of the Turbo and is angled,now on the GT25 plus many more; the intake snout is just a short prodtruding section sticking directly outwards? how do guys fit up the intake pipe to these??,I mean like will my stock rubber intake pipe fit on a GT25 and using the stock Exhaust Manifold too or do you need a custom intake pipe??..

buy these http://justjap.com/s...378&cat=&page=1
then any s15 turbo including the stock s14 or s15 t28 and use all your old turbo bits except the turbo oil dump pipe which you'll need to use a universal fitting and a piece of hose to your fitting in the block.

Thanks for the link ,but I was talking in regards to Turbo's with the intake snout section like this http://www.google.co...d=0CGoQ9QEwBjgK with no bolt on snout, how do fit up the intake pipe?,custom pipe or could the stock Rubber pipe still be used?

infact it is a brand new turbo inside stock housings.
Results from a customer with G1 spec high flow results based on a S15 T28 turbo on a Sr20det None VCT 180sx with Pump 98 fuel.
