Some assembly notes for these:
I have cut down one of the elbows, the end which goes onto the turbo adaptor. Have some gasket sealer/Tiger Seal or silicon (automotive not bath!) to "lightly" smear onto the ID of the adaptor, just a minimal smear to make a full seal as there's only 0.1mm tolerance to the turbo's Od - Too much and it will just extrude everywhere and make a mess. Also add some loctite onto the two grub screws when you screw them onto the turbo's intake. They will sit into the turbos groove on its intake.
Once you have fitted the adaptor to the turbo and tightened the grub screws (dont go daft they are only going into aluminium), then you can push over the cut end of the 76mm 90 bend. **I found it easier to assemble the parts with clamps fitted but not tight, and used washing up liquid on the hoses (NOT ON THE CUT ELBOW TO TIP ADAPTOR THO, IT WILL KEEP SLIDING OFF!!) so they can be adjusted easier to align everything nice. Once you have added all the parts and made any neccessary adjustments to the hoses and angles for your induction setup, you can then tighten the clamps.**
Where you may want or need to adjust the lengths of the silicon bends to suit your induction setup, I have found doing a hose clip up onto the pipe to act as a cutting guide, and using a very sharp stanley type knife along the clamps edge, gives you a nice square cut.
Open induction filter users will find the install straight forward, the OE airbox ones will need to trim hoses for the correct fitment.
Any questions please ask.
all the best
