So, like many of you I have an R33. Like many of you I have a return flow (Cooling pro stealth to be specific).
Like many of you, I dream of 300+ Kw. I have the supporting mods for it, I have the turbo for it. I have a good tuner, good injectors, good ECU and a healthy engine.
What do?
There seems to be four options.
1)
The easiest option. A return flow cooler kit. Usually Blitz or Cooling pro. Both appear to get massive pressure drops at the core and tao from hyper gear recommends not running them for anything past 250kw (I think it was 250??)
2)
Top to bottom style. No off the shelf kts for a skyline but requires minimal piping to fit. Piping is shorter than return flow. But how is the pressure drop? is it better? I have read a few good things, but still not a lot of info.
3)
A "same side" cooler with one end take with inlet and outlet. I imagine the end tank has two separate chambers? This means that the air has to go all the way through the cooler twice effectively to go out the outlet?
4) *No image*
Home made return flow. 2x 90 degree bends at the far side and a long pipe. Better flowing? longer piping? gooooood? bad?
What is the best NO CUT option for those of us who just can't cut up a daily that won't pass an engineers cert (Damn air bag!)
