993 engine manuel vs tiptronic
Hi
I am thinking about swapping an 3.6 engine in my 75 coupe (have done it before on another car). There is a 993 engine fs, but it comes from a car with tiptronic. Is the ecu different from the ones with manuel and can I use this engine and ecu(can it be chippet for a manuel trans if there is a difference)Is there any difference on the engine for manuel vs tiptronic? |

Mechanically speaking, it is the exact same engine.
There is a couple of things that are different, and if I am to swap a Tip engine in a manual car, it would take me 5 minutes to adapt. 1st thing is a cable that goes out of the engine wiring harness to the manual gearbox for the reverse gear signal. On Tiptronic, reverse signal is from lever. I happen to have this bit of cable if one day you need it. Second is a slightly small alternator belt, that you could swap for the manual belt. In Tiptronic, while you are on a stop in gear, rpm goes down to 600, so to compensate alternator speed, a smaller belt is used. To adapt a larger belt, you remove shims between pulley halves and you are done. But for the ECU, I am practically sure it communicates with the tip box Brain, so The ECU might be different. Have to check on the PET or parts catalogue |

ok thanks for your reply
The engine is for sale at a brooker with or witout the ecu, I will have to pay extra for the ecu so I could buy the engine and get an ecu for manuel else where. Is it the way to go or can the ecu be chipped to work with a manuel trans? |

This advice is worth what you pay for it but you are best off using the manual ECU rather than attempting a reprogram of the one for the automatic..

If I buy an ecu from a manuel, can I use the wiring from the engine or will I need to buy wiring from a manuel to ? |

The DME or ECU for Tiptronic is totally different from Manual. Buy a manual ECU.
The wiring is all the same. Engine harness is the same but missing one cable for manual transmission, I can send you the cable free, or you can buy a new harness for $120 ish It is the same harness for both tiptronic or manual. What price is the engine going ? do not go above 4 - 5 thousand $ The tiptronic engines are cheaper because a lot of breakers do not know that it is the same engine plug and play Last edited by geolab; 03-21-2012 at 04:23 AM.. |
