right he was the problem ,i needed a large turbo with quick spool ,for air effiency which they don't make , as this turbo is/or was a geniune garrett gt40 4intake , problem was the hotside it was too laggy due to size of I , 1.14 t4 twinscroll , so after searching for another hotside//but smaller they don't do one , so next option chop the buggar , yes its cast , but its cast steel with nickel contnt so can be welded ,,, so after chopping a large area off , and useing spring high tenile steel 5mm thick ,i knew it would work but how well was another story , anyway 4 hours later , it was time to try , bare in mind ,when first fitted I had major turbo lag and showing 5000rpm before boost came in , after customizing the hotside I'm in boost at 2600rpm ,lol with no surge and will pull clean to 30psi , mental , but I dearnt risk trying to tunie anymore as I'm on stock headbolts lol ,, no point in buying exspensive pistons/rods/bolts etc , long as its tunied its fun ,,, its when you get greedy and go that bit more then somert jumps out of the engine ,pmsl ,,
