f-max or drag turbo kit

i've been looking at turbo kits for my 99 b18b and have narrowed it down to these 2. f-max seems more complete. it seems that you don't have to buy anything else besides what they give you. the drag kit doesn't come with a turbo timer, or a compression lowering head gasket. what do you recommend?

You can get the drag kit with a turbo timer... or at least I did when I bought it a little over a year ago. The compression lowering head gasket doesn't though. Personally I'd say go with drag, but either one is good.
