what would be the best engine swap for my 86 duke? i have been kinda leaning towards the 3800 because of its pretty decent mileage and good horespower for its size. and it seems like a common swap. what would you guys recommend? im just getting ideas so i can start looking for a "doner " car.

That is the L67 or 3800SC you spoke about in your first post. Honestly, it's not the easiest. I have yet to find an "Easy" swap. Remember you are going from a factory installation to a custom installation. You will have many "Custom" parts or fabrications involved. From the research I have done (since I too have the same car and want an engine swap) the 3.4PR is the simplest. Again, my research and I have not done this. Those of you Fiero geniouses can elaborate on that.
However, I am looking toward a 3400 (most likely candidate) or a SBC 327. I can get my hands on both motors for around $300.00. Just determining the best fit for my application is the hardest part!
Your not going to find an easy swap per say for the duke. if it was a V6 you could drop a 3.4 in easley but it being a 4 there is going to be some rewiring for F/I

The easiest swap is the one you pay someone else to do for you.
A lot of the challenge of a swap will depend on your skills. Are you good at welding and wiring? Do you know how to program a ECU? Do you have the tools needed to pull an engine and/or rebuild an engine?

You could swap in a 2.4 Quad. Thats a nice little 4 banger and even better with a Turbo. I haven't seen anyone swap in one for a while now.
does that engine have more power than the tech4 ? if so how much more? what car used it? sorry for the questions lol im just currious now i have never heard of that swap

i am okay at wiring programming i know nothing about really. and yes i do know the basics of how to pull and rebuild an engine. but that is all the point of my fiero :P i bought this car to tinker with and enjoy it and learn things along the way so ya the easiest swap would be to pay a proffessional to do it but then i wont learn anything other than how much it cost to pay them to do it :P witch i can imagine would be a pretty obscene amount haha. it is an option to pay someone but i would have to ship my car away, (no one in my area can do swaps really) and i dont have the money to pay for one at the moment. i just want to buy a car from the wreckers with an engine i can tinker with and maybe one day make it work and get it into my fiero once my duke dies on me but i do understand what your saying

This link has got the answers for you. I think its a bad a** little four banger. One day I will have a Fiero with this engine and a 5 speed in it.
sweet ill check it out! thanks. and i have the 5speed duke on my 86. do you happen to know if the tranny from the duke will fit the 2.4L?
I believe it should. But if you find a car with the 2.4 Quad in it and it has a 5 speed, use that 5 speed instead, its a better match for the Quad and its more durable, Rodney Dickman carries the kit for it to work in a Fiero. Drop this in a Fiero and you will be all set.

dude this engine sounds so bad a$$! 250hp i believe it says for a turbo on the engine is pretty good for one version of the quad 4. i think thats awsome. ill deffinitly look into this engine more but i think as of now its getting to be my top pick for a swap reading about it

do you have a link to the kit to make it all work in a fiero? is it on Rodneys web page?

Rodney's kit is for the 5 Speed Tranny out of the Quad 4 Donor car. The transmission is different as far as linkage and slave cylinder goes, Rodney's kit solves that. Its the FWD Getrag Kit.

Its not going to be the easiest, but there ain't many around anymore. Here is Some Reading for ya....

Keep good fluids in it and probly will never die Unless you consider a timing gear failure dying

so true. come this spring she is getting all new fluids! it does not leak any fluids witch is awesome. or burn any even better. and ya i have heard they are great reliable engines if you treat them right they will treat you right so i will for sure keep up on it and keep her as long as i can!
