ok so I may as well make this clear to start with. I dont have a DSM. I do however have a turbo 4 cylinder car. its a 1987 XR4Ti. Not a whole lot of support for these cars so getting any help is next to impossible. So I figured the DSM club would be the next best place to come can;t really think of any other popular turbo 4 cars out there locally.
So anyways heres my issue. the car has a turbo 2.3 litre with a rather over worked Garret t3. theres no IC, no BOV, nothing. this is stone age turbo technolagy. Boost kicks in stupid late at around 3 grand red lines at 5.6 (yuck). but around 4.2 the engine sounds like it doesnt; want to rev anymore and all power just completely drops off. its as if I just drove into a deep puddle. So this gives me a power band of about 1200 RPM... kinda useless. So my question WTF IS GOING ON!? its suposed to pull to red line and it doesn't.
