2.8 stroker works great..

[tntprocomp]

So I pulled the 2.8 from my Fiero..Put in 3.1 crank,bored 40 over and with higher compression pistons,444 cam and headers..Also ported and polished Plenum,runners and heads..The power increase was more than I planned on..I wasnt trying for a race car, just an improvement..For the low cost and not a bunch of time, it was well worth it..I jus wanted to post this for anyone else thinging of doing this..

Pics please. And thank you for building a not so loved engine. I sure miss my 3.1! I had big plans for that engine on the rebuild.

[tntprocomp]

Its actually still the 2.8 engine, just stroked with a 3.1 crankshaft..I like the reliability of the 2.8 intake system and gaskets so I didnt use any of that stuff from a 3.1..I will post a few pics..

Isn't a 3.1 just a stroked 2.8 anyway? Making this a 3.1 after all?

[Superdave]

Yep, 2.8's and 3.1's are the same block.. all 3.1's are stroked 2.8's.

Yes, plus a good performance cam and 40 over high compression pistons..Its around a 3.3 liter now..

compression ratio calc says 3206cc.

[tntprocomp]

So it is above 3.2...lol

Can those bores take .040 over and still last?

[Superdave]

Yep. not much more though.. i've heard of .060 after a very thorough inspection but at that point it's just easier to start with a 3.4 block.
