Hey guys...some of u know that I'm doing a v6 swap into my 4cylinder fiero...I just thought I would give an update every once and a while to tell u how its going. I'm going to start taking pictures so they'll be up soon but for now I'll let u know what I'm doing and please give me feedback. thx. I own a 1984 2M4, 4speed. Now its way to slow for me. so I bought a 86SE Parts car. With a v6 in it. The plan is is to put that v6 in my 4cylinder car. Now I have heard alot of stuff on how hard it is because its an 84...I'm going to do it anyways because I know it has been done and can be done. anyways so far I have taken the v6 engine out and am totally stripping it and rebuilding and probably adding a stroker kit and maybe boring it out...so it will either be a 3.1 or a 3.4...haven't decided yet. So far I have the engine off the cradle on a desk with the oil pan off and I'm getting ready to take the pistons out. the cradle is almost bare and is almost ready for painting and new bushings...thats my progress so far...thx for the space...

Sounds like you're on the right track. I did this conversion on my '88 coupe. The difference is worth every single trip to the parts store, every swear and cut!
It took my mechanic a very long time to do the conversion, but he did take care of me for the long wait. If I could figure out the PIP I'd show everyone!
My mechanic said the worst part was either the V6 fuel pump, or the throttle cable. We didn't swap radiators, and mine has never gotten hot.
Hey! Thx guys for all the reply's...ya I'm loving it so far and learning so much...I'm following the hanes manual and learning along the way...I've taken quite a few mechanic courses in skool but nothing that got this indepth. And no I'm not boring it out to 3.4...I'm boring it out 30 over to 3.1 and then puting a stroker kit on therefore making it a 3.4. And then offcourse redoing most of my engine with performance parts or whatever...I'll start taking lots of pic's so I can show u guys the progress visually...
Anyways thx again for the feedback!

I do not believe so...do it the other way...put a crankshaft on from a 90 transport van with its 3.1 engine and ours becomes a 3.1 because of longer piston stroke. Now just bore out the engine 30 over and were at a 3.4(3.899).

trust me, look it up. the crankshaft will bring it to 3.1, but boring it over isnt gonna bring you to 3.4. i believe that will either bring you to a larger 3.1, or maybe a 3.2. i just dont want you to be dissappointed when you find out later.
It was done...I saw it on a recent meet with my club...bored and stroked to 3.4...it was an indy car but with a v6 in it...could it be possible? I dont' think this guy would lie...

Sure a V6 indy is possible. I forget who it was but at the Dutch Classic II there was a fellow with a fastback turbo Indy, basically he customized it the way he wanted it. There was no stock V6 Indy. You will still have a 3.1 or 3.1+a few cc. The 3.4 is a different block with a larger bore, I believe if you bored out a 2.8/3.1 to the bore of the 3.4 then there would be no clyinder walls left. (that would be good no friction at all oh wait you still need compression! Seriously before you tear apart the 2.8 check it out maybe it does not need rebuilt
O trust me ...she needs rebuilding...and she's already torn apart...well nwo I'm thinking of a different stradagy...another guy in my club is looking into a turbo design so if I stroke my engine to 3.1 then completly redo my valve train with performance parts and performance pistons yada yada yada...I'll probably get around 195hp???? and then if turbo goes threw...well...say good night...
It is possible to make a 3.4 out of a 2.8 block a company is already doing it. They refuse to sell the kit only a long block for the 3.4 version. Something about having to test the 2.8 block vigorously if you make a 3.4 out of it. Here the 2.8/3.4 stroke block is on ebay: http://cgi.ebay.com/ebaymotors/aw-cgi/eBayISAPI.dll?ViewItem&item=600289228
Gizmo...the project has slowed down alittle bit because of the winter conditions here...and budget...I still need to get the block diped and then I'm going to start rebuilding it..my goal is to have to done by april...hopefully it will happen...and the main plan I'm going with right now is to stroke it to 3.1 then turbo it.

I have an 85 2m4 that i am going to stick a 6 in. I am thinking about going with a carb so i don't have to mess around with all the computer crap. Don't have a block yet i am going to go get it as soon as i get my tax chack!!

Hey Lance, are you rebuilding in your garage or are you doing it at school? Also, if you bore out the engine to a 3.1, won't that (get ready for a engineering term I learned in school) Compromise the structural integeraty, giving you a powerful engine, but limiting it's life dramatically?
Hey Jesse!!!!! Never knew u were on here... I'm not actually boring my engine out now like I said in a few posts up...I'm going to stroke it to 3.1 and then put a turbo on...my goal is around 250hp. Then we'll see who's the king at budwiser park...
