I'm using a small turbo for a number of reasons. I am familier with the large turbo efficiency etc etc but I am also poor and can't afford a larger turbo, sc14 are hella expensive as well I couldn't find one cheap. I have spent $150 on the turbo setup thus far without including the stand alone which I can reuse on other projects. 100 of that was a good condition turbo, 20 on the manifold.
Plus Mine is an n/a engine with the high comp pistons so I can't run high boost so the smaller turbo won't be working to keep up, the only issue is the reduced flow at high rpm will mean there will be a high backpressure in my exhaust from the restrictive exhaust wheel meaning at 5500-6000rpm it will hit the wall. This car will be focused on rallying so a small turbo is perfect anyway because my only advantage thus far has been my cornering and corner exit speeds. If I get into a horsepower race I will lose, there are guys at my club running 400hp v6 supercharged engines, they are heavy though I brake then throw the car like a madman to keep up so if I had any hesitation I would be in the trees. Good stuff all the same though there are plenty of misconceptions about turbo setups out there and well researched info is hard to come across.
