I need to replace the turbo on my '99 V70XC AWD automatic with the 2.4 l engine (code B5254T). Can anyone tell me what the difference between the 13G and 13T are? I am getting conflicting answers as to which turbo is correct--the Mitsubishi TD04HL-13G or the 13T? According to one dealer the Volvo OEM part code is 8601692 which should be the 13T but I've found the same part code with a 13G. What's the difference? And can I upgrade only the turbo to a more higher performance unit without having to do any modifications? Does anyone know a really good rebuilder? Also, I'm a newbie when it comes to the pros and cons of the low pressure turbos vs the high pressure turbos. My V70XC seems to be down on power--or at least what I am expecting from a turbo-powered engine. I never feel any boost or experience any turbo lag, but the dealer "supposedly" looked at it when I had the recall replacement of the throttle body done and pronounced it healthy. Is this because the turbo is a low pressure unit? What settings in the ECU mod should I pay attention to? I also have noticed more white smoke from the exhaust than usual but not clouds of it--usually upon idling and acceleration. Any suggestions here? THANKS VERY MUCH!!

i have used cherry turbos who have rebuilt both of my R's turbos. good work and fast turn around time. the no lag is because of the low pressure turbo. you will need to find the R version of your model and start swapping, but i am not sure about it working on your 2.4 since the high pressure turbo is a different engine. best to leave it as is and if poss, sell it and get an R. easier and cheaper.
