yea there a bit of trial and error involved to fit it to a classic, maybe even the older classics could be more tricky, im not sure is the throttle body in same position on 94 as a 99... there an excelant intercooler, 400bhp no problem, think Andy F runs something like 450 or something for road use, be handy fit for someone that has newage wrx as i have no recirc valve, so newage owner could just use his re circ or dump valve on it.. mine has been around now for a while and came from a jap car that was in uk, so aluminium isnt mint in it, wouldnt be a show piece or anything, if it was going in a detailed bay i would probably polish up the aluminium, i payd 350 euro for this and found it hard to get one when i wanted it, used it and then went fmic
