They should be pretty easy to make, just get right thickness sheet metal, cut to desired size,make a few bends, few coats of hi temp enamel, easy bake oven it and install.
This is for IC guys or/and others, I have seen some cut up SS pots(cooking) and make them fit over the turbo. Talk about DIY
Chatmanboy, Your paint is ok now but trust me with time and no shield, your paint will crack,fade in that area. If plastic emblems are melting above it, think of the paint. Underhood stock liner, we all know it doesnt last by inself. Out HA turbo heat will eat away at that in no time without a heatshield. Best bet is a Turbo wrap,homemade bigger, better Heat shield, thermo underliner.
The turbo wrap would work best IMO, since it does a few things, lowers engine bay temps, helps spool faster, Heat shield wrap around entire turbo. I don't think it looks nice but I plan to order one, what the hell.
