This thread made me almost die laughing..wtf is that pic of the car doing here? Random.
Anyway, t3/t4 del sol, ANY turbo can be setup to run external WG, and who knows what this guy is running. He could also have a cheap ebay mani that will allow him to run a t25 and/or a t3 flanged snail. The downpipe would be just about the only thing needing a change in any case. But NT.
Anyway, save your dough and get the t3/t4 now, don't do this shit twice. Its hard enough to do it once and do it right.
