Looking for a t4 twin scroll exhaust housing and from what I've read the ATP 1.06 housing is prone to cracking.have they fixed this issue? Or there is some mystical 1.15 housing that I can't seem to find. Or Garrett makes a 1.00 housing but haven't seen much about how this does. Anyone have any thoughts

 

I have been running the ATP 1.06 for several years with no cracking.

 

Was the casting ****ty looking? All the stuff I can find is older threads and some of them said that ATP was going to re do the housing but can't find any info on if they have. The ones that said it cracked said the casting didn't look that great.

 

ATP redid the castings. The older stuff was terrible. I had a few crack.

Depending on the turbo PTE has some really nice housings. I have used both 1.15 and 1.32 housings and have been great so far. The design of them is much better then the ATP stuff. Its also more even between each volute and smoother.

 

It's going to be for a hta3582r
