I should have specified my Fiero is not a Fiero duke block, but a Super Duty 4cyl. However, there is not a whole lot of difference between an s10 2.5 duke and a pontiac 2.5 duke. Same design really. S10 block just has a little stronger mains and thicker deck I believe, and starter bolt holes on the opposite side. Fiero 2.5's like to grenade if you push them much past 125hp. With a marine crank or SD4 crank and a stronger head and internals s10 duke will put up with more. as you see in this vid

Fiero is a 2.5L Pontiac Iron Duke ... S10 is a chevy 2.5L ..... two very different animals!!!

230 hp? really?

[SPARKPLUG910]

Lol im going to talk my lil bro intotrying this for his Fiero haha

im going to throw a 3.8 in mine it would be a fun experiment

I have one of these SD4 motors in my Fiero. For an early 80's 4 cyl these motors are very impressive. Consider these motors have been built to over 300 HP naturally aspirated. That is more HP than Mustangs, Camaros and Vettes made during the same 80's era with V8's.

That is comparing a race 4cyl vs. stock V8's, but still....

i want one just like it , 2.5 chevy race motor for my s10. Where????

[jacktheripped]

Ok, where did you get the oilpan? is it a stock one you modified?

[TALLSACKwithoutLOVE]

@Spiegelmeister if it is, then its not out of a fiero

[vidsharing10101]

a 2.5 can be built to have some power. roller lifters,sealed power makes good rings,get some good bearings and polish the intake and exhaust on the head and use good head seals/valves .check out my build videos on here

Shweeeet. Pontiac SD4. Bolt that into a Fiero, give it the balls to go with the looks.

[Spiegelmeister]

thats a pontiac not a chevy..sigh

[kovu86]

my 86 S-10 has the 2.5L in it and pull a 16 foot car trailer with my Fiero on it to the strip from time to time and never have a problem with power, granted I converted to a tall ratio overdrive 5 speed and have 4.10 gears in the rear end

[holymuledeer]

How the fuck can you get 230hp out of a chevy 4cylinder. Fuck sakes I have the same god damn motor in my s10 right now and im getting 120hp from it. The only way I could think of you doing that is slamming thousands of dollars for performance parts. These engines are known for lasting long, not going fast. I guess what i'm saying is i'm jealous. hmph.

[asuwolfram]

Gotta love noisy, old 2.5L engines =)

[frosty9595]

Carbed 2.5L engine putting out 230hp? That pretty damn good even by todays fuel injected standards.

[danaandbillsmith]

I have an 89 s-10 with a bad 2.5 .... how much would it cost to make a good performer maybe 125-150hp? because at this time I can't find parts for it... like steel cranks, rods, heads, intakes, I know I can get a cam. Any leads  will be a big help to me. I do have headers and a 700r4 for a V-8 swap but we just put a 383 in my brothers s-10 jimmy and he spent $7500.00 on it (but its NASTY!!) and I don't want to get that deep in it

[seriouslybeach]

is that the super duty 4 cylinder? i've got one w/ 500hp. u know where i can find out more info about it? im tryin to sell it

[dtpchilli4life]

I was contemplating building my motor in a similar fashion.. But I think a rebuilt 4.3 would be a better investment.. If you have the money to do this though, why not? I've never heard such a mean sounding 4 banger haha awesome.

[jacktheripped]

@robert30319 10038470 It's for the Super Duty head and says only but it's easily modified to fit

[robert30319]

[Green88S10]
