I personally would not touch TD with a barge pole, that turbo was fine on my car and was sold to johnsy as so (cant remeber it being cracked but hey ho they are all like it) my car ran 420bhp and 380lb ft of torque on it! without issue, i have had bad experiance with TD and there expert rebuild's (one of which failed very quickley), i now use owen developments and they are far better in every way, just bolt it on and enjoy it ,it will work well up to 450ish bhp. it is about the best turbo for linarity you can fit to these cars. ps it will sound like a jet engine straped to the car when on boost and 1.5 bar is it's sweet spot.
