Its the 87-88 performance rebuild kit from the fierostore

I think it should work wouldnt it, or are these pistons going to be to small for a 3.1?

 

Going by Fieros only having a 2.5 or a 2.8 engine and you having a 3.1...no.

I bought my kit for my 2.8 from them. Lots of options to build yourself a strong engine, and reasonably priced.

 

You can use a 3500 FWD crank and have the rod journals turned down from 2.499" to 1.999" and you will have a forged crank

I have two if you want one $75 plus shipping (has 23,000 miles on it).


The 2.8 pistons will not work in your 3.1. The pistons will stickout of the block because the wristpins were moved to allow the same rods to be used in both engines (and allow the longer stroke).

 

If you hang on to that till after I get income taxes (or my bonus check from work, which ever comes first) I'd be quite interested and willing to pay some more if you can have it machined and then sent out (I dont know of or trust any machine shops around here)

 

I cannot, for the life of me, figure out why anyone would rebuild a 2.8. Look at this first:

It would replace your 3.1 as well. Or, you could do this one:

I can't believe that once you add machine work in, you could do better with that kit listed above...

 

I rebuilt my 2.8 for $800, including all the machine work. Shipping is another $165 to my place on that engine, for a total of $1052. I could do better than that even if I had to buy the parts to be machined.

 

But all of those parts are NEW. I can't see beating a new engine for less than 900 bucks. With warranty, I'm sure the shipping is extra, but I see people routinely pay hundreds at the machine shop.

 

I'm not rebuilding a 2.8, i'm rebuilding a 3.1 and was going with forged internals so as to add boost. I've already bought a 3.1 from hawks now I'm just trying to find a source for forged pistons, and I saw those at the feiro store and figured it was worth a shot. for 1800 bucks i expect more than 194 ft/lbs TQ...

I'm looking for at least 250TQ to the wheels when its all said and done. i'm hoping for 200+ wheel HP also. (nothing insane, I'm looking to rev to 7500RPM but if the parts to do so come cheap enough then I'd like to have them so I know I can rev to 6500 consistently.)

 

Both are gone since the post, but I should be getting more soon. Send me a PM when you are ready and I may have another in stock.

Most NAPA's are a trustworthy machine shop.

 

I think what people were trying to say is that that kit is or the 2.8 v6 and the pistons are different. You probubly already know that by now, I just thought Id throw it out there anyways.

 

Yea I figured that part out I'll definitely take you up on that here in month or so. (if sales stay good I should be getting a 450$ bonus.)

 

Damn, pm me as soon as you get one firebird.

Demonknight- you can't use the probe pistons unless you have them milled down to fit. Not sure how much you'd need to mill it cause I don't have the piston specs. Someone in germany did basically the same thing to a set of flattop 2.8 pistons to fit them into a 3.1 a while ago. He only had to mill them down .1325" and I would imagine the probe pistons would'nt be too far off from that.

 

by probe do you mean feiro? (or did I completly miss somthing lol)

 

No, they are modified forged Cosworth/Ford pistons

GM is not the only one to have the same bore and pin height.

 

Probe is the manufacturer.

 

I feel dumb now, I thought you ment a ford Probe car.. the later ones look awsome I test drove one, but it just didnt feel right.. ya know what I mean?

 

Yep, I'm not a fan of fwd either. Ironic that ford has their own 60 degree v6 they put in the probes. The vulcan v6's are based off a diesel block though, and don't have nearly the part selection you do with the gm 60 degree.

 

is it possible to replace a 3.1 with a KLZE 2.0?

 

Why would you want to do that???
I do not approve of this move or the thought of it.

 

Why would you do that?

 

torque? fuel economy?
