Finally I have had my holset hx32w running on my 1jz vvti. I bind the eBay 44mm wastegate in favour for a turbosmart gate. It has now been on the rollers and I’m not overly impressed with what I have achieved if I’m honest. I’m on a 12cm rear housing. 3” downpipe and system. I made 463bhp at 22psi. Looks to come on boost at 4200-4500rpm Is there anything I can do to the turbo to make it perform better?
