Not sure, but I know it's not a T3 and it's definitely not the one you want! The photo's kinda blurry but an a/r of 89?! Wow! That's lots of air intake! Judging by the double outlet flanges, I'd surmise it's for a V8. Check
www.turboford.net in the 'For Sale' section and watch Ebay for the proper turbo.
