I've got a vRS and the boost pipes have packed up so I'm choosing now to remove it. 

I don't want to be spend ridiculous money, I'm just doing this before a remap. I want to keep the EGR and ASV (I'm going to black and ECU map it out).

I'm only wanting to push 170-180bhp. What would anyone recommend. The Darkside seems to be the best but I can't justify 750 quid for it.

You can get that with a generic map, standard SMIC and a Swiss cheese job on the inner arch.

from my understanding I thought it was 160 standard map and 170 with an intercooler. 

Is the intercooler the first bottle neck?

No, it just heatsoaks quicker.

Yes and no; at 180bhp (dyno measured) you start running into heat soak with the SMIC and a solid RH inner arch. The Swiss cheese won't give you more power but will stop the heat soak.

How far can you get with just a stage 1? Celtic tuning claim 180? Anything else that I’m better off doing before the remap? 

Get a Seat Sport style one if you're so keen on an intercooler. It's a proper pig to fit proper but it'd be the best bang for buck.

Ebay or wherever will sell knock offs. An intercooler is an intercooler, darkside is seat sport style iirc but with some brackets welded on.

 

My 2 cents is that your standard intercoolers probably got some leaky pipes at the age of it, and being a plastic intercooler could well be leaking a bit already.

They're all the same dude, about 165 BHP, the numbers are marketing drivel, it could be stage 7 for all I care, if you're on the standard turbo then there are two maps available, torque limited for high mileage clutches or the full monty.

Torque fella, this is NOT a petrol engine, big intercoolers won't make moar powah without bigger turbos!

But it will reduce heatsoak on those lovely summer days just around the corner.

Thank you global warming. 

Diesels on boost a lot more than an equivalent petrol so heatsoak should be more of a concern, am I right in saying that?

Heatsoak in a diesel reduces torque, in a turbo petrol it can lead to detonation, diesels like hot air, petrols hate it.

On the BLT engines theirs a map that reduces boost based on intake temps. If I remember right once you start going past 70c intake the boost starts to reduce which in turn will reduce how much fuel is injected as they are both linked.

 

The ASZ ecu map doesn’t really have that map configured as the smoke map is based on the MAF sensor. On the BLT the smoke map is based on the MAP sensor.

 

on a stock car and map one third gear WOT pull will see you into the 70c intake temps. I once’s logged intake temps around Oulton part and it was at a constant 70-80c which in return reduced the boost pressure based on the above info. Mine was an ASZ but I switched the smoke map over to be MAP sensor based.
