Turbo to induction filter hose
Turbo Mini Forums

Longtime lurker, first time poster. So be nice.

I’m struggling for space between the bulkhead, radiator hose, timing cover and everything else to fit a tidy induction pipe. I’ve got a 90deg silicone hose or a normal metro turbo style bendy pipe but I’m not convinced either will last. As it’s still tight and I’ve canted the engine over as far as I can.

I suppose the question is, if I drop from a 60mm to say a 50mm hose from the turbo inlet, will it affect the performance too much seeing as it’s an HIF44 carb?

You should have clearance, but then again where are you trying to duct to. My hose has an armored cuff so it's fairly larger od than the compressor inlet, but my air filter is under the inner wing so routing is easier than anywhere else in the engine bay

Own the day

Probably over thinking it. I'm running a 52mm tube from the turbo to a filter at the front and made 180bhp at 18psi.

There’s enough room if you make it. I have a 70mm hose on mine.

Do not til the engine forward.

Post a picture of either what you're trying to do, or trying to achieve with placement.

And pipe size in the atmos side, and boosted side do not correlate. Keep it simple and keep the hose the same size as on the turbo inlet itself.

I've done the same, 90 degree silicone then a 45 degree joiner to the air filter. I never got on with the convoluted pipe stuff, always ended up with holes and tears.



This probably shows it better..

Thanks for the suggestions, I’ve got the original T3 set up along with a silicone 90 that I’m trying just to get passed between the bulkhead and it’s tight between there and the radiator lower hose and the actuator. I haven’t got as far as routing yet which I’m open to over the top of the thermostat housing or through the wing or just by the wiper motor.

I think I probably am overthinking it a bit but in the past I’ve had the convoluted tube wear and hole as it’s so tight.

I’m wondering if the bulkhead box isn’t over far enough. Will post a pic when I can.

I guess nobody makes the ERA mini turbo air filter enclosure anymore to fit the filter in the passenger wing area ?

It was a neat option

Yep mines practically a 90, very little chamfer. I’ve gone for a 60-52 90 deg silicone hose and it seems to fit nicely with an aluminium joiner. But, I wish I had that chamfer like you with that much room. Thanks for posting the pics all, been a big help.

If you want a filter for under the inner wing, just go visit your local scrapyard and find something suitable.
