harry yarnell Posted January 28, 2020 Share Posted January 28, 2020 I've got the opportunity to pickup a'95 Riviera with the supercharger. Parts car. The thought was to transplant the engine ( or just the supercharger) into a Reatta. I know some on this list have done just that. I'm open to comments, and advice on this endeavor. I've done transplants before; 4 speed powertrain from a Corvair into a VW bus. 3800 powertrain into a Fiero. All run great, and like bats out of Hell Link to comment Share on other sites More sharing options...
padgett Posted January 28, 2020 Share Posted January 28, 2020 Whole car is best so you get all of the sensors, wiring, and computers. I may still have the program for a Buick L67 in a Reatta. Stock program and heads/injectors will run too lean up top. Also need s/c MAF. Others have done more recently. Link to comment Share on other sites More sharing options...
2seater Posted January 28, 2020 Share Posted January 28, 2020 I agree, the whole car allows for all the little odd stuff you may need. As for transplanting the whole engine or just the supercharger, it really depends on why the Riv is in the yard. If the engine is sound, it makes the most sense to transfer the whole thing. If the engine has problems then it may pay to transfer the top end to an existing LN3. I planned on doing a transfer to a fresh LN3 long block I have and I have a complete 95 s/c engine on the stand and am debating maybe resurrecting the s/c engine? In any case, when the engine was pulled for me by the salvage yard, they left the torque converter attached to the flexplate. When I checked the part number of the torque converter, I found it was compatible with the LN3 and 440T4 trans in the car. Sort of a bonus.

padgett Posted February 5, 2020 Share Posted February 5, 2020 And the 95 computer is programmed to use with an 91-on "E" trans. If a 440T4 or 4T60 probably best to copy the 95 engine maps onto a 253 computer. Link to comment Share on other sites More sharing options...
D-a-n-i-e-l Posted February 6, 2020 Share Posted February 6, 2020 The transmission and engine can be ran off the original ecm. Just expect to replace and upgrade your transmission shortly after. Link to comment Share on other sites More sharing options...
harry yarnell Posted February 6, 2020 Author Share Posted February 6, 2020 How about swapping out the proms? Link to comment Share on other sites More sharing options...

Two different programs/ECMs. All you need is a prom adapter and programing. Sinister performance does mine.
