The hks ssq I got from my old mans scooby p1 lol I borrowed it it only hit limp mode once after that it was fine I'm only not running it now as I had to give it back . I had to buy a 25mm bung that was about £ 8 . I now have a different set up all together on my car and love the sound it makes its stupidly loud . Have a look in readers rides or a post called high temp paint in here I think
