For some reason z20LETS make insane torque with maps and clutches cannot cope and a consequence is poor standing quarters and traction particularly in the wet. My friends Phase 3.5 was insane in the wet to the point he had to get the switch to turn it off when ever it was damp. | |

It seems to be the case on most new turbo engines that dump valves are a no-go. | |

Depends how much he wants to spend. It's easy to get alot of power out of them. | |

My mate has just bought an astra mk4 SRi turbo, Z20LET, same as the astra GSi and is about to buy a bailey dump valve, why does he need to be warned mate? Do they mess up the engines? | |

Regal have just released a tubular manifold which is flanged for Garret GT series turbos, but they say it's only for use with forged pistons and steel rods :o | |

VXR turbo is only about £600 IIRC. That and a map (so im led to beleive) is aroun d £270 as long as your exhaust fuelling and injectors etc are up to the job. Oh and a larger SMIC or FMIC is needed. | |

courtenay or regal for ideas but would personally get or do most of the stuff yourself if you can | |

My computer illiterate mate has bought an Astra GSi turbo (MK4 shape) and is looking to have a slight play with it. |
