Hi lads my girlfriend bought an altezza few months back only had it 3 days when the belt broke causing 4 valves to brake its a manual altezza having no money to fix she left it... 3 weeks ago she decided to try get it fixed as cheap as possible we left it in to a shop to be skimmed and have the broken valves replaced but yesterday they told her they cant get the valves :angry: so i have been looking at getting just the head the only one i can find is an auto head, i know the valves are different but will the head just fit the same an be down 10 bhp or is it a complete different head, im going to collect it 2moro but dont want to be wasting money i dont have thanks James |

He asked if the auto head would fit even though it's a manual engine, the answer is yes it should fit. Don't know if it runs fine on the Manual ecu? Question is though, did the pistons and bore get damaged by the shattered valves? At the end of the day you can buy a whole engine for $1k why not do that and just throw it in? Could end up cheaper at the end of the day. And have you tried talking to xNickx to see if he has any valves in stock? |

I'd be very surprised if there was any difference between the auto and manual head. Generally toyota never make distinctions like this - it makes no sense. Please at least try to punctuate and structure your posts in here, it may 'only be an internet forum' but if you expect a considered answer - try proof reading your post before you 'add reply'. |

There are differences, Manual are titanium valves and bigger, with different cams too, slightly higher compression. Auto are Steel valves and smaller, slightly lower compression. They also have different rev limits. I think they done this to avoid the Auto versions being horrible down low, as the auto one does make its max torque alot earlier. |

There is a difference, Matt. The manual head has larger, titanium valves. They should be interchangeable. Not sure about the ECU though. I know Corey is running an auto head, but he is also running a Power FC |

Unfortunately sorry to say Matt they are different, ToyoDiy is a very old EPC system which can give wrong details (a huge headache for me!) SXE10 6MT Inlet camshaft - 13501-88570 Exhaust camshaft - 13502-88570 Inlet valve - 13711-74140 Exhaust valve - 13715-74140 SXE10 5AT Inlet camshaft - 13501-88560 Exhaust camshaft - 13502-88571 Inlet valve - 13711-88560 Exhaust valve - 13715-88560 The 5AT 3SGE also have a lower rev range and use steel valves where the 6MT uses taitanium. A few members (TurboTezza aka Corey) have opted to go for the 5AT head with the steel valves etc for their engines. |

Well that sucks, guess you better find a manual head. |

YEah Sorry Nick - I found other sources confirmed otherwise as well. What a PITA to have mech differences from auto to manual. |
