Hello
I have recently decided to build a turbo buick 3.8. I currently have a n/a 3.8 block from the early eighties out of a pontiac grand prix. Can anyone tell me if there are any differences in the block, heads, crank, or rods.
Thanks

If your thinking about building a '86/'87 style motor then all the parts are different...

Actually i wasnt thinking about the year model, i just wanna know if there are differences in the block, crank, heads, and rods from a n/a 3.8 to a turbo 3.8. I am totally new to buick v6s so bear with me. i want to build an engine capable of low to mid 11,s
Thanks

Not worth it in my opinion. If you are starting from scratch buy an '80s 4.1 from the junk yard for $200 and build one of those. At least you will get the correct crank, rods, heads ect. You'll end up with a non original motor either way, but you'll have 21 more cubes and unshrouded valves. powersix

The only reasonable way to the low 11's is the 86/87 configuration. What year block do you have? an 86/87 109 N/A block will be the correct block, heads, rods, but you will still need a crank, brackets, intake, ecm, wiring harness, etc.

It is probably cheaper to find an actual complete TR motor for $1-2K with all the pieces then starting at ground zero and trying to piece one together.
