Rally is a ton of fun. I'm still running TSD rallies though, haven't got the funds to run a Performance Rally yet. Some of the events like the one pictured from last weekend are a ton of fun anyway, a couple hundred miles through the woods on all dirt/sand roads in the afternoon/night with lots of opportunity to drift and muck about without wrecking your car

I like RallyCross too, I have some excellent videos I'll be putting online of some great RallyX events..
My intake is a wonderful 2.25" mandrel bent piece acquired the ghetto-fabulous way. $2 at a junkyard. That's right, many old school turbo Volvos used this piece as an I/C pipe
The I/C piping is all custom, I bought from another GVR4 owner when he wanted to go larger. I'm running a Starion FMIC which hasn't really proven to be much better than stock SMIC.
I'm still running a stock 1G MAF system but I have a neat little BOV check valve that lets me vent to the atmosphere but prevents rough idle and that nasty super rich condition when you shift with a secondary 1-way valve and a small diameter return back to the intake. Another New England Club DSM trick. I want to upgrade to a 2G MAF at some point for better flow, and I have an S-AFC already so it should be an easy swap.
