Questions... help me out!

1) There was someone on here selling the center consul 1>3 gauge pod, i can't remember where to find it (searched but still no success). I want one so i can run a cd player!

2) I'm going to upgrade at least to a koyo aluminum radiator and B&M oil cooler, will i be okay with just the tmic for now (i have an '87 turbo)? I'm averaging temps around 93C cruising and around 110C when i'm going up some of the big hills around my house. I will be shortly making a long trip over to the east side of washington and need to know if i'll make it over snoqualamie w/o running ice on the tmic

3) Boost creep... running 3" DP and 3" corksport exhaust... I've been told that porting the wastegate is the way to go; but then i went to a local shop and they recommended an external dump tube. Any opinons?

1) Im positive that this was www.speedmachineperformance.com
2) The intercooler and radiator are not really related at all to coolant temperatures. The radiator cools engine temperatures, the intercooler cools intake charge temperatures. Upgrading one or the other will decrease temperatures to their respected areas of the engine.
3) An external dump tube? If anything, it sounds like an external wastegate. I would agree that an external wastegate would be much much better than the stock internal wastegate system, but unless you want to get a new manifold and turbo, its not going to practical. Porting the wastegate is the most cost effective way to eliminating boost creep. I believe the largest it can be ported (s4) is about 48mm's. Don't finish the porting project unless you do the maximum

1) 1FastT2 was selling console plates.

2) has been answered.

3) Port the wastegate and you should be fine, shouldn't need an external dump.

yeah just port the stock wastegate if you're not running an upgraded turbo. If you were using an upgraded turbo you would most likely have an external wastegate and not be asking this question.
