I've completed my NA-T conversion for around £1200 + road mapping. The car drives great, i havent had it on a dyno but judging by the cars i've had a play with i'd say its a good 380BHP @ 6PSI boost. I looked into the TT transplant but remember your only getting a stock engine, to get close to the power i'm running you'd need to go BPU which will prob be around £1500 extra for a decent exhaust, FMIC, etc. For me it was a no brainer £3500 for a BPU TT transplant or £1200 for a bolt on 380BHP done in my garage at home without ramps or powertools! Its the white Sup in the DEC issue of Japanese Performance. Scott
