trouble is, that review is blatanty written by some bandwagoner whos never tried one tho, esp as used the famous pic thats been round the internet for years and you dont even see that turbo for sale anyhow.
saying stuff like "most petrol application turbochargers are watercooled,none of these are(costs too much) and they don't feature integral wastegates(to complex-too expensive to manuf.)" is not just total shite (ie tons of modern turbos arnt water cooled), but not even correct (ie i actualy have a water cooled, internal wastegate, ball bearing cored turbo, that was made in china, in a box down the workshop)
there tons of companies making these turbos in china, some may be shite, but most arnt. if they ever were, seems like it, theyve learn from their mistakes and realised they better off making decent ones, as it still costs fuck all at their labour rates compared to ripoff UK etc.
i know for a fact more than one tuner in the UK (non cossie) that sells and uses "chinese" turbos under their brand name with no issue.
i also know for a fact Holset have tested the copies of Holset turbos these factorys make, and found they perform pretty much identically, tho generally arnt quite as well made, but considering the money, the off the record comment is, they suprisingly good.
its the knack of knowing WHICH ones is the issue.
most people in this world consider a "T4" to be pretty much all the same type of turbo.
hell, technically my GTR turbo is a T4, and its rated to over 900bhp...
