I have just rebuilt my standard turbo carb but when i took it apart there was no jet or needle! what is the best position 2 set these so that my car will run? The car is a 988 turbo using a modded standard head and a stock cam with an intercooler. the needle is a BDD |

Hard to say. But using the BDD, wind the jet right up to the top, then back dowm 2 1/2 turns.

Check that the actuator is shut.

i have blocked the plenum hole and that checked that the acuator is shut but still no difference! wat should the fuel pressure be at idle? could i have it set to low low so when it starts to boost there is not enough fuel?? |

Fuel pressure should be 3.5 - 4 psi at idle On 11th Feb, 2015 robert said:

If you look at the rear face of the carb. There is a small drilling on the right hand side near the bolt holes. Should be a matching hole on the planum. Make sure the gasket hasn't blocked it. On 11th Feb, 2015 robert said:

What turbo are you using? If something is worth doing, it's worth doing half of. |

And are you driving the car or just revving it on the spot? If something is worth doing, it's worth doing half of. |

Get it setup on a rolling road. you risk damaging it if you don't On 11th Feb, 2015 robert said:
