Water to air intercooler for 1kz-te - cheap ebay or high end kit?
Hi everyone, I have a 2002 hilux with manual 1kz-te turbo diesel. I want to add an in cabin Boost tee and do the potentiometer mod (link to reddit post) but before I do this I need to get an intercooler, I was looking at some ebay front mounts but I have decided to get a water to air intercooler. I am trying to decide between getting a $600 ebay kit (image 1) or a $2000+ propper branded kit like the PWR kit (image 2). Now I know the PWR kit will obviously perform better, but by how much, And is the increase in price going to be worth the increase in performance? These high end intercoolers like PWR are made for performance race cars, not specifically 4x4's so im not sure it will be necessary. I have seen a video of someone who put an ebay 4" × 8" barrel kit on their 1kz hilux and they said they did not notice am increase in power but did notice a slight increase in fuel efficiency (link to video). Will a longer barrel be better? I am looking at a 4" x 10" barrel eBay kit but I don't know what length is best for these engines. If you have any advice, knowledge or have done this in the past please share! Thanks
