HI marcel does the engine look like this-
or like this-
The first one is a 1990 and the second is my 1993 tpi. The best thing to save is as much of the wiring harness as possible. Every thing else is easy. When your ready to start the swap I can help you work out the problems. Just work on one problem at a time and try to think anything that you are doing now that could cause problems latter. |

Blair..... question! what year and make was the engine used for your swap? I just picked up a complete 1991 buick lasabre limited with 123,000kms with a pristene 3800 v6 series one and a 4t60 all running. Going to start tearing apart this week. Any secrets/suggestions? Planning to keep all running gear together for a fiero project.... Still need a reasonable fiero though Marcel |

Drove the car on the road for the first time last night. I had to put gas in the tank so I could make it to Dales alignment on sat. Needless to say the car doesn't track vary well yet. I had no problems with the engine or trans. The overdrive gear has the car purring quietly at 80km but when the car is floored you can hear it! ( from about 3 miles away.) Acceleration is just a little better than a 3.4 but it's way better than the 2.5L the car had. I still have some minor electrical problems in the dash to tweak out and I may need to think about a bigger muffler. All in all I 'm happy with the way the swap went. |

Think cleaner,faster,and better on fuel. I put my 283 up on Craig's list for $1,300 just to blow it out the door. I will be selling my hp 2.8 for $2,ooo or so. A third of what it cost me but the 3800sc will be in the car permanently! When it starts to seem slow I will just bump the hp up. |

Heres a pic of the rear of the motor showing the crossover pipe. The exhaust exits on the right between the #4 and #6 cylinders.

Blair from the looks of your exhaust you must be using the stock 3800 crossover pipe to join the 2 banks. I would like to see a shot of the upper side of the exhaust system. It looks like it is something similar to what GM did on the 4.9's.

In BC only 88 Fiero's are required to have a cat converter. The 2.5 4cyl that was in the car runs even when new, much dirtier than a newer 3800 motor. From an emissions standpoint the 2.5 and even the 2.8 from a lesser standpoint were a really bad design.

How are you going to get away with not putting a catalytic converter on it? Reducing emissions is a good thing

Crossover pipe? Cat? What is in the pics is the whole exhaust. The engine is from a front wheel drive car so the manifold exits in the rear. Installing the exhaust in the way I did significantly lowers the heat in the engine bay. The engine also breaths better even with only one tip. Infarct it may breath too good for the tune ports fuel calibration. On a side note, I had a stumble when the engine was revving up so I installed a new mass air flow sensor and wow. It now has some attitude. Here is a pic of the left side of the exhaust without the tip on.

I used a modified Fiero exhaust hanger to support the system on the right side. On the left I cut the clamp off and welded a 2 1/2" clamp on. The pipe is wrapped with exhaust wrap between the engine and muffler to control heat in the packed engine bay.

The exhaust system is built and installed in the car finally. I made it from 2 1/2" mandrel bent pipe and a Moroso spiral type muffler. The whole system is the shape of a saxophone and not much bigger. I ordered a stainless steel Bora twin slash cut tip to keep the 2m4 look but the engine sounds more like a v8 than a Duke.
