Power

Intercooler should be swapped as well when going to RS2 power levels imo.
Also, Jamo is right. Fitting a proper exhaust manifold does wonders for spoolup time.

I have a bit different car, but by fitting a proper manifold my turbo started spooling 400rpm earlier...
Full boost in 2nd gear by 3000-3100 instead of 3400-3500, makes it more responsive down low as well.

Jamo:-

Si already had the remap in his previous post

Where's that?

I saw he had driven a 350 bhp car but didn't have one as his car was on 280 bhp homefry type chip

Rusty:-

I added the quote to clear it up but you must have missed that. Si had remap on his to do list, I added some other things.

Also Si, you'll want to look at the fuel pump and regulator depending on how high you go.

So an RS2 EM would be a good starting point then?

Price progression:
1. Ebay RS2 replica (cheapest, 180 pounds or so)
2. Used RS2 manifold
3. Wagner tubular, but probably better to use a cast manifold...
4. Wagner cast

Unless you're planning to run over RS2 power levels or have lots of money, I don't see the use of getting 3 or 4.
I run an ebay replica myself, as do lots of people over here and none of us have had issues with them cracking...
