I have collected quite a few bookmarks, thought it would be handy for anyone else interested in proven modifications for the 2.5L Duke. I have given credit to all the original sources, if you prefer I pull this data down or have any other concerns, please do not hesitate to contact me.

Also, to all the old schooler's, please feel free to add or provide any additional data that will be of some use. I know the common question is "why go to all the trouble and expense when you can just drop in a swap with more power per dollar" For me that's easy, I like to do things different, want to preserve my car as close to original as possible. And it's just plain fun doing things differently.

I appreciate this board, all the information provided to me, and the deals made in the Mall that's making my project possible. If we were all the same, life would be boring.
Worst case scenario, if it all implodes, there's always an Ecotec waiting in a JY somewhere nearby.....

Without further delay, here's my site: fiero151

I know some of you old timer's are sitting on a treasure trove of data, thoughts, ramblings etc.
Please share so it's not lost. Full credit given, PM me if you have something to share.

Later I will expand it with SD4 data

Actually the Iron Duke performance tips shown on Iras website were written by and credited to S. Joe Wynman of Patterson NJ about 12 or 13 years ago when he was president of the now defunct Tri-State Fiero Club.
Ira may have followed Joe's plan in his performance Duke build. IIRC, Ira was happy with the result, his engine stayed together but he apparently received an offer for the car that he couldn't refuse and sold it years ago. If you want something different this type of build may be what you are looking for but it may be the ideal mod for those that want a bit more zip and wish to keep the stock appearance of their Fiero for car show competition. I believe that the 120HP Duke claim may have been an estimate.

Here is my 2cents .... instead of spreading the data all over the WWW why dont you do an "Iron Duke all you wanted to know" thread here.... that way the data will never be lost in the years to come. I have seen MANY good websites disappear into interweb oblivion because of lost interest. I would suggest concentrate the data here on PFF and then you can spread the word via links.
I commend the hard work you are doing....
regards
Danyel

Good point, but I did choose the Wordpress format since it's stable and has longevity. I'll figure a way to funnel it back through the board.
Also will have a plan to pass the reigns if need be. Thanks for the feedback!

I was under the impression that the Crapler/AMC 2.5 was an entirely different engine, even though it uses the same bellhousing.

One thing I did to my stock duke was drill out the cap over the fuel pressure regulator adjustment screw and turn up the fuel pressure a few turns. This is something I found by searching the archives here. It helped throttle response

I notice that the Jeep engine is already rated at 120 hp. I wonder if anyone has put one in a Fiero.

The 2.5 used in the later jeeps is an entirely different engine. It would be almost impossible to put one in a Fiero. As a matter of fact, it is impossible to put one in a Fiero.

I was looking through the website and noticed the picture of the 552 casting head. That is a picture of the head I bought off of Ebay for $79. That head is now on my '84.

Yep, seller in Indiana? very nice guy if so.
I hope the buyer of my Fiero takes my advice, goes this route.
Looks like they'll continue where I am leaving off.

most of this thread is pretty much guesswork and misinformation, just scroll down till a guy named stroker s10 starts posting, its longwinded and on a s10 forum and there is a buttload of information.

Thanks Josh, that's definitely "Top Ten" material. I wonder if I can get in touch with him, I'd like to include his info for archival.
Unfortunately, I will be leaving the Fiero community soon, but would like to pass the torch. Anyone want to take over the Wordpress blog, keep it up to date?

I can add stroker's info, it will remain up until Wordpress pulls the plug.

I updated my page with strokerS10's invaluable wealth of info. Long winded and read, but worth the effort for those after something special and money to burn.

I'd like to clear up some more misinformation and maybe someone will correct me if I'm wrong. Only VIN R blocks will work in a Fiero. VIN E and A blocks from S10 trucks do not have an opening for the side mounted water pump.

welp, There was a great fiberglass forum, that everyone posted all types of great info on, as they always "assumed " it always be on the web..
only way to get to it now is the internet wayback machine
http://web.archive.org/web/...fiberglassforums.com

so spreading the info to more than "just" one site is a good idea.
