Title: serrated edge on my turbo
Post by: DR SCHNITZEL on January 12, 2009, 08:48:26 PM
You cant see it properly but there is serrated edge around  inside of the turbo, has it been modified in some way and what will the impact be of this if it has?

its a second hand hks to4r kit.

Yeah it spins now like dream dude the hot bit wasnt on tight thats all. should have a new oil feed for it tomorrow too.

Yes im talking about the compressor housing. the inner edge looks like its been crudely filed. ill post up a few more pics. its a hks to4r kit.

these pics show much better what im on about it looks as tho its been opened up for more flow!!!!:Hammer

looks like it\'s been machined down, but after a quick look on the Garrett website it doesn\'t seem like it would affect the turbo\'s performance? i may just be completely way off understanding turbo jargon, but seems to me that Garrett are saying housing size doesn\'t matter, only the trim.
