Improve RS2 intake/exhaust

[EspenW]

when at 4k upwards theres lots of air flowing far too fast to gain temperatures from warm engine parts. same principle appllies with cone filters.

That is interesting information, indeed. So if the air is moving so fast at 4K+ that it can't absorb thermal energy from hot engine parts, it is also unable to lose thermal energy to cooler engine parts like an intercooler?
Will a cone filter always provide more power than an airbox above 4K?

The stock rods can work with RS2 setup, 3" full exhaust without cats, MRC high boost remap, RS2 replica EM, wagner IM and intercooler kit? Or it can be bended?

How much power and torque can I obtain with this improvements?

There are plenty of tuned RS2s out there with standard RS2 engines, the RS2 rods are the same as S2 ABY/AAN and they don't bend. It's up to you what risks you take, if you're rebuilding the bottom end then replace the rods, if not then just be a little careful that you don't go too far. I know David MidnightblueS2 is running K27? turbo with standard rods, it's just been mapped to be on the safe side.

What folks would say something about DBR hand made intake manifold? Apart from price.

[MarT2]

Ported and Polished head is agood plan too

In what consists a ported and polishead head?

Expensive and there are other options. Repo and Carsten both have reverse intake designs.

Ported and ploished head will increase flow, also cams with bigger lift.
