The stock plastics ones insight hair pulling to remove / install and they bend and give and that is with the subframe removed.

Yea my rear turbo pipe loosened up over time and it was a PAIN to try to even get that back on.

The word is that those are increased in ID at the inlet and outlet. I believe the inlet ID was specified and was quite and increase, the outlet ID (at the turbo inlet) was specified to be increased as well but a specific measurement was not provided. If that ID was increased sufficiently, then would be a great part to buy. If not, then total waste. From appearance alone it appears there was some significant increase so all should be well.

I mixed up In and Out in my description, sorry on my phone. The Inlet seems fine, the outlet is what makes them pointless, IMO. Again, WHY not just make the ID slip fit the stock gasket on the snout, WHY neck it down at at all? I'm just trying to understand the thinking there, if you are going to cast such a nice looking piece, make it flow as much as possible

Rob@RBTurbo · 01-28-2013, 01:42 PM

Nothing wrong with necking it down, provided the final ID spec is a good match for the compressor inducer. The jury is still out on the exact spec. Something tells me though that they did a good job optimizing them to the housings potential.

We can agree to disagree I guess, do not see why they would put that step in there. Just have the ID slip fit the snout gasket, no need for a step. As I said my opinion. They do like nice castings though.

Anyone running that intake kit? Isn't like $2,000 USD?

It is difficult to say from the photo. If you have an extra inlet tube you could look at your piece and the pic and try to guesstimate if the outlet id is larger than stock. Since nobody has measured / reported the diameter, I'm afraid it is not increased.

I am curious to see what happens with some testing with them. They look like they are well made

Rob@RBTurbo · 01-28-2013, 02:37 PM

Agree. Only issue was cost being astronomic.

I asked if its not possible to just cut off the ends on these pieces and use silicone adapters to connect and also make wider. Not a good idea ?

No Reason why it wouldn't work. Just don't like cutting up $2000 dollar castings. If the necks don't reduce much it would be pretty extreme to cut them off and use connectors. Has anyone actually texted the stock pipes and seen how restrictive they are or aren't?

I'm sure he meant cutting the stock tubes and saving the money.

Alpina_b3_Lux is running these. He says the outlet diameter is the same as stock.

This would make the most sense but I don't take anything for granted on these forums anymore.. hahaha

Well the OD diameter has to be the same as stock to fit the turbo snouts. But it looks like they did increase the ID of the inside opening. How much not sure

Rob@RBTurbo · 01-28-2013, 04:48 PM

I looked into making mold ends for the OEM tubes and weld/glue them to the original inlets to reduce the unnecessary and severe flow limiting taper. End result was a cost I was unwilling to stomach. It actually made the price from those other offerings seem much more reasonable. Great idea though if someone has some great connections in plastic forming.
