I agree with Chris.
Go for a set of Turbo Technics "stock replacement" type hybrids. These are the cheapest option T.Technics offer, definitely not any sort of stage 2 or 3 hybrids with enlarged compressor wheels or clipped turbine wheels. Ring them for a chat. I have had a lot of dealings with many many "turbo" companies in the UK and would recommend T.Technics and Universal Turbos. However I've never had Supra turbochargers from Universal Turbos.
These replacements are running on one of my cars and I have had zero issues with them (been on car for several years now, approx 22,000 miles). As I stated earlier at 1.3bar max, my EGT's have not gone above 800 degrees. Typical running at 1.1 bar daily max I don't see above about 760 (ish).
