serious2a Posted July 19, 2014 Share Posted July 19, 2014 Hi, I have two 19J engines, each with different sized turbos fitted. One has a Garret with the following numbers on it :- BC2 M27 A/R 48. The other has an Airesearch (amalgamated with Garret, I believe), turbo but I cannot find any numbers on it. I need to know which engine has the correct turbo on it and a part number would help in this respect. The two turbos are of different sizes. The Airesearch (smaller) turbo is fitted to engine No.19J149620. The engine number has been obliterated from the other engine (for reasons unknown !). Hope someone can help me resolve this question, Thanks in anticipation. Quote Link to comment Share on other sites More sharing options...
Phil Hancock Posted July 19, 2014 Share Posted July 19, 2014 AFAIK the original fit was a Garrett. Quote Link to comment Share on other sites More sharing options...
western Posted July 20, 2014 Share Posted July 20, 2014 there are 2 LR part numbers STC99N = New turo assembly STC99E = Exchange turbo assembly maybe one of yours was a Exchange item, parts book does not give any further details of turbo maker or their part number Quote Link to comment Share on other sites More sharing options...
serious2a Posted July 23, 2014 Author Share Posted July 23, 2014 Thanks, Guys, for replies. I contacted my local Land Rover parts supplier with the STC99 Number and they confirmed this was indeed the number in their parts book. Unfortunately they were unable to tell me any details about it - what years it was fitted, size, etc. so I'm still in the dark. I had read on some forum about another turbo number - ETC6878 and I mentioned this to them and after a bit of digging they found it in their books but could tell me nothing about it. The odd thing about it is this - the engine with the smaller Airesearch turbo on it looks original and undisturbed whereas the other engine with the bigger Garrett turbo on it has new bolts fitted which would lead one to guess that it might have been changed at some stage. So, I'm still left not knowing which of my engines has the correct turbo on it. Any guidance as to where to turn next would be much appreciated. Thanks again.

western Posted July 23, 2014 Share Posted July 23, 2014 suspect it was a pre 1988 turbo fit as that engine was ypdated in '86 IIRC. Quote Link to comment Share on other sites More sharing options...
