Attention: TDR Forum Junkies I just got a new turbo to go onto my truck. I am trying to figure out what size exhaust housing is on it. This is a new housing. It does not have the markings on it like the orginal one on my 93. The casting number is 35619-410 on the exhaust housing. There are a couple of other numbers on it to. just below the casting number is a 129. There is another number right beside it. It is a two degitt number. I can make out a 1 but the second number I can't make out.
I am hoping someone knows what size it might be. If it is a 18 cm I'll just throw it on and not worry about breaking my old one apart. This is a H1c model turbo also.
I could find any info over on holset website.

On the outlet side it has HOLSET 18. 5 CM and below that is 3519-410 there are some numbers on the other side of the casting, but I can't see them too well. When you take your old turbo off the truck, just put the exhaust housing next to the new one and compare the size. If it's a 21cm you'll be able to tell because the inlet passages will be taller and fatter, not by much, but enough that you can see the difference.
