Hi peeps,
So I have a BMW E87 1 Series with a Toyota 1uz V8 manual swap which I want to know Turbo Charge. I am also from South Africa and finding info on Holset Turbos is impossible. I plan on boosting between 11-18psi
I have been doing some research but the information is contradictory so please can you help.
The Turbo I am buying is a HX55 which one I cannot tell you fetching it this week. I am paying 90usd for it and its in good condition
I am getting it for cheap and plan on rebuilding it and also adding a billet compressor wheel to also save some weight on it.
I am really stuck on the exhaust housing side as there is contradicting info this what I know just wanna know if its legit
*HX50, HX52 and HX55 exhaust housings are interchangeable
*HX40 housings can be modified to fit HX50's so surely I could get this to work on a HX55 ?
*aparently the hx50 or hx52 came with a rare housing of 14cm
*I have checked the A/R ratios and this is what I have found
6 cm2 = 0.41 A/R
7 cm2 = 0.49 A/R
8 cm2 = 0.57 A/R
9 cm2 = 0.65 A/R
10 cm2 = 0.73 A/R
11 cm2 = 0.81 A/R
12 cm2 = 0.89 A/R
14 cm2 = 1.05 A/R
16 cm2 = 1.21 A/R
18 cm2 = 1.37 A/R
21 cm2 = 1.61 A/R
I am looking for 1.05 A/R ratio housing for the HX55, but I have seen that a few people have measured these and the sizes from above is different. So now I dont know which one to choose.
I have also looked at this thread and it has given me even more A/R Ratios

Thank you for any assistance you can help me with
I have attached a pic of my car haha
