1.8 20v SMIC?

What size is the core? You need to maximise that, particularly if youre not going for a bigger turbo.

Also, you can't compare the perv turbo power produced to the derv one as a benchmark for how good it is. The perv turbo will be producing a hell of a lot less charge temp as the turbo is way better sized for the application. A t2/k14 by comparison is running outside its efficiency almost as soon as you play with it, hence the charge temps jump very quickly, and heatsoak is far more pronounced...

Another thing to factor in is that almost any intercooler set-up will support a singlle 220bhp pull on the dyno, provided the dyno fans are good and it's not sat there heatsoaking for ages. It's being able to support that power without it heatsoaking for even a 5minute hard drive that's the most important thing to look at too...
