Hello,

I was wondering what kinda mods people did inside the 2.5 iron ducky engines to make them go faster? Im bored and got some $$ to burn .

Thanks

quack lowder.

Hooker Tri-Y Super Competition Header. Get rid of that dinky high school metal shop reject exhaust manifold. Years ago mine cost something like $200.

I have an MSD 6al and blaster coil on my DuckMobile. I dont know about better performance, but economy is pretty good. I added a "dual exhaust" v6 muffler to help with the sound, removed the baffle in the air intake. I have thought about taking the flow "wedge" out from under the throttle body to see if it gained any top end power, but I figure that GM must have a pretty good reason for putting it in there.

Hey, Racer 1...If you've got $$$ to burn, I need a loan! Seriously, if you want better performance, why not replace the 4 with a 6? Kick Hill sells the 2.8 and (supposedly) all of the change-over parts for less than a grand. Then you could rebuild the 2.8 into a 3.1 (or maybe 3.2...hmmmmm).

WKDFIRO,I already got the super comp tri-y's $230 from summit. I polished the TBI body on the inside.

Monkeyman,I thought about that but working on a 2.5 duck is hard enough I could just imagine a V-6 in there "HEADACHE" to work on.

I wanted some thought on how to squeeze out some EXTRA HP from inside the Duck make him fly alittle faster.

RACER 1
GET BEHIND 2.8 GT OR SE AND ASK FOR A PUSH OR YOU COULD LOOK FOR A CLIFF BUT THAT MAY SCRATCH THE CAR. WHAT I DID IS I GOT A CAM NEW PISTONS I HAD THE VALVE HEAD DONE NEW CRANK AND NEW MAINS ALSO THE HEAD WAS SHAVED AND NOW SHE FLY'S RIGHT.

Eddie--There's no need to shout. We're all friends here (except for that guy that ripped Tom off). In case you don't know, you are shouting if you type in caps.

sorry I did not know that some times I hit caps when I go to hit tab I work on a mac (G4) its not mine but ts nice and fast

hey eddie i got your part # for that header and the phone # you gave me did not work! could you check that # again and also i called summit and they said they had no such header called a tri y? i need to buy a header today or tomorrow so i can put my motor back together! were can i find one!
thanks

Set fire to the son o' a ***** !!!

Oh, sorry. I'm probably the wrong guy to ask about "the DUCK" at the moment. (check "mo' '88 Coupe problems" thread)

AAAAAAAAAAARRRRRRRGGGGGGGGGHHHHHHHHHHHHHHHHHH!

My G-D are you insane set fire to my DUCK. Shes getting old and needs some TLC'ing from the inside not lighting her on fire and sticking her on the dinner table for thanksgiving.

SloPonti I think it was #4208 hooker super comp tri-y I got mine from summit just tell them you have a 2.5 ducky motor in your Fiero.

did that header work with the OEM exhaust or did you have to make something.

Sloponti
its the right part number but I did call summit and they can still get for you .
by the way hows your car coming along I had to put mine on ice for little while Iam helping out my mom with some things right now. Eddie

the car is coming along fine and i have the new motor almost put together and the old motor almost out! i am trying to work on this exhaust stuff! i have the same question as the orge! eddie how did your header work with your exhaust? did you have to modify it and racer 1 how did yours work with the tri y header?
thanks for all your input! as soon as you guys answers the questions i will be on the phone and ordering my new header and exhaust based upon your answers!! i can't wait!!!!!

Eddie--no prob about the caps, but you really need a better computer (i.e. something other than a Mac). I know they aren't cheap, but you can get some good deals on them these days. I don't know what the difference is, but my brother-in-law is a computer programmer and he said that there are all kinds of probs with Macs. I've got a Gateway with a 550meg PIII myself and love it. It was a present from my wife for my birthday. Sorry to get off the subject. Just giving you my opinion.

My tri-Y header bolted right on all you have to do is weld it infront of the cat. Hooker also make a 4 into 1 design but it doesnt have the O2 sensor mount. http://fierorob.homepage.com/DSCengine8.JPG hope this works look up at the top on my website page here the tri-y goes straight out of the head then goes down.

Monkeyman, you wish windows was half the OS that's on the Macintosh. No I'm not starting a flame........ I use service and make my living of Wintel boxes. I've done so for Mac and Wintel since they wher both invented.

Eddies problem is caused very simply by the diferance in keyboards and some inatentive typing. It has nothing to do with the mac. If I moved you from a good IBM or Keytronic keyboard to the cheap slag that has buttons on most systems then you'd likely have the same problem. same problem moving from a cheap KB to a good one.

I only use IBM PC-AT & PS/2 style keyboards at home. I've put them on every machine but my girlfriends Compaq. If I use her machine, or one of the ones at work with diferant KB's I have to nearly relearn how to push even one button. allot of the stuff they push for keyboards these days should be trashed. Even some of the "ergonomic" ones bite. Yeah they are a bit more comfortable but they are built out of the same crud.
