i just don't know about using PVC pipeing for a Turbo. the air going thru the turbo is going to get quite hot so for short runs it wouldn't be bad but for a long trip id be a little scared. from what ive read some were some pvc pipeing can give off nasty fumes when heated to much.
as for the rad cap its a little red neckish but i guess it will do what it suposed to.
