Aye, that sounds right to me, and your picture is what I was trying to get at but it didn't really work, hehe Of course you'll need some short lengths of hose to connect the breathers up but need to know what size (inner diameter). You could maybe get away with using the original piping and chopping it to fit, since your alloy t-piece will be in about the same place as the crankcase breather that might actually work. Saves you buying any extra piping, etc Just need to check the original pipe work will fit over the outlet of the alloy t-piece.

so you know when im getting measurements, say the outlet for the t-piece is 50mm. If i get a plastic t-piece, does that want to be 50mm aswell, or a bit bigger?

were getting there mate

If the inner diameter of the pipe is 50mm (which it won't be but for arguments sake ) then the t-piece needs to have an outer diameter of 50mm. They are usually barbed in order to give a tight fit.

last thing then, does the piping go over the t-piece or inside it. not the outlet bit, the main part?

The alloy goes inside the silicon When talking about solid pipes (alloy, steel, brass etc) the diameter given is (more often than not) the outer diameter. When talking about flexible pipes (silicon, rubber etc) it'll be the inner diameter. Occasionally it's the other way around (PC watercooling being one example) but for cars that's a general rule.

right okay mate thanks a lot

Will get on with ordering and no doubt more questions will probably pop up lol

confused yet again.

Here are measurements:

Outer crankcase breather: 24mm.
Inner crankcase breather: 20mm

Outer manifold breather: 12mm
Inner manifold breather: 10mm.

That's fine, but the outlet on the alloy t-piece can only be 25mm and no smaller on their shop.

And, the plastic t-piece will need to be 20mm to fit on the alloy outlet, and the crankcase breather at the other end.

Also, the biggest plastic t-piece they do is 10mm outer diamter.

Something is a miss here.

F***, i wanna get it ordered

Dom

Haha that would look extra tidy

Nah seriously this is driving up the wall

The 25mm outlet on the t-piece will be fine, once you've got your jubilee clip on the crankacase breather side it'll make a fine seal. I'd get this - should be exactly what you need

Don't forgot you'll need about 25cm (if that) of 25mm rubber hose to connect the crankcase -> plastic T -> alloy T and a length of 12mm rubber hose to go from the plastic T to the inlet breather, maybe about 50cm.

So just to clarify:
1x 70mm/60mm 90 degree reducing elbow
1x 70mm alloy T-piece with 25mm outlet
1x 70mm 45 degree elbow
1x 25-12-25mm plastic t-piece
70mm cold air feed ducting
Length of 25mm rubber hose
Length of 12mm rubber hose
4x25mm Jubilee clips
2x12mm Jubilee clips
1x60mm Jubilee clip
4x70mm Jubilee clip

Phew

How tidy would it look if the crankcase breather pipe didnt exist lol.

The question still remains, why does that GSR only accomodate the bloody thin one.

Either way, im getting ordering!

I think the GSR outlet is actually a 25mm, and it probably came with a t-piece and the associated piping. Probably.

If you want any assistance getting it fitted let me know

Will do mate, thanks a lot. Got there eventually!

The 45 degree 70mm is £20 :O

On £45 and thats just 45 degree, 90 degree and plastic t-piece!

WORD OF ADVICE TO ANYONE PURCHASING FROM AP: ring them before purchase! a red, 70mm - 60mm silicone 90 degree reducer = £19.60 + £1.95 postage.
Rang up: he gave me a product number and same product just different name + £16.00 free postage

use viperperformance its a lot cheaper - silicone hoses are not 'cheap' items

thanks a lot! im up to £63 quid here.

any ideas where to secure the hosing etc? or just use existing air bracket
GymJunkie: £16 for 45 degree silicon hose, nearly £30 on viper

Click to expand...

I just checked their prices and Viper are more expensive than ASH. The only thing that'll need bracketing anywhere is the BMC itself as it's quite heavy.

yep okay mate £70 in total

what type of rubber hose is it btw?

im guessing its air line, but thickest is 13mm
