I Disagree. I done conversion (Turbo Bolt ons) to my 4.0 BA Fairlane Ghia , You see A xr6t is not & will not be A Fairlane hence me doing this.I wanted to mix prestige/Luxury with some performance. In your case well xt is basically the same just a pov version Eng/Drive line/Interior. But The experience & knowledge you gain doing the conversion is great also fun "At times" so I say go for gold mate ! All up my Ba Fairlane Conversion after the list I will put below where installed by myself & mate's plus Flash Tuner Plus custom Dyno Cost $2,500.00 Not bad for A now Fairlane Ghia with 285rwkw (safe-tune) on 98RON Turbo Exhaust - Ebay $80-100 TMAP2 Sensor - $110 Delivered (Ebay) The Std cold/hot piping/Cross over & Std Ic (Intercooler) Generally like the turbo exhaust come all together - $80 Look around boost Cruising/Ebay/classifieds for your turbo & Manifold & Dump - generally they can sell as package " Turbo - Manifold - dump pipe" $500 - $600 The Std Plenum you can ether take out the butterflies & use it or find yourself A turbo one with out them "I have seen people with the STD NA Plenums when doing this conversion" They say it adds extra Torque. - $Time You Can keep the Factory ECU but in doing so you must run a manual Boost controller. Boost controller $50 AutoBarn. Also you will need to drill & Tap into the sump to add your oil return line. M8 for tap 10mm for hole. $15 -$20 Oil feed line. I got mine custom made $100 Oil feed line. Brass T $10 Water return line I got A brass T & taped into heater rubber hose = $25 Water feed line I taped into thermastat housing NOTE : Tap under housing as it isn't free flowing above housing. I used 1/8" tap = $8 Also NOTE: When fitting the TMap2 Sensor Reverse wires *** 1 , 2 , 3 , 4 *** *** 4 , 3 , 2 , 1 *** I may have left out A few bit's & pieces but this is the bulk of it. : Say $1000 - $1200 Flash tuner SCT2 - $600 Includes Generic Tune to get you to the dyno SUB TOTAL $1200 Flash Tuner $600 = $1800 + Then all you will need is A custom Tune.
