tcd makes quality kits, but they are priced at like 55xx.. im in the same boat bro.. 95 m3 here too.
make the smart choice.. i cheaped out when turboing one of my 3 series' before and regretted it and redid several pieces of it more then once. just do it right the first time.
if you really are budget, get a quality (666 or TCD) manifold, quality name brand turbo, and a good source for tuning. the rest is easily fabricated.. but a good manifold and turbo and tuning is key to making the whole thing work well and reliably.
i was planning a garrett gt35r, Tcd cast manifold, and still havent found good source for obd1 motronic programming yet.
