Still flying at 30,000 feet! Expecting to survive more than a single pass down the strip at over 12 psi on a 5m is gonna require a programmable stand-alone ECU and major mechanical modifications in the neighborhood of many, many thousands of dollars, especially if you don't have the mechanical skills to do it all yourself and have to pay for all the services. A couple of guys on this forum do the 7m-gte swap as sort of a side business and they'll run you $5000 to $6000 US to swap in a freshened, but bone-stock 7m-gte, which is nearly minimum wage considering the work involved. From there you can follow at your own pace the typical upgrade path of the many mk3 owners learning as you go. Turbocharging a 5m at any level is really something that ought to be left to those who revel in the do-it-yourself automotive hobbies and who chalk up every little unforeseen necessity and minor disaster as merely the cost of their education.
