One of those eBay electric superchargers would work very well for this purpose, but you really only need it when the car is sitting still or creeping in traffic.

Rather, heat shields are a much simpler solution.

 

I didn't have any heat shields with my T2 conversion stuff that I bought recently, so just how much of an air gap do you recommend for the heat shield? Also, which items need it? I'll look into the FSM tonight when I get home to see what the stock ones cover, but in case you have any other recommendations for additional items for heat shielding, I'd like to hear it.

 

1/4 inch is fine. The manifold, turbo and downpipe should be shielded.
