Quad 4 swap (lot of pics) (Page 1/31)
sardonyx247 JUN 19, 04:54 AM
I am swaping in a Quad 4 DOHC High Output 2.3L into my 87 base couple daily driver.
I thought I would share the tons of pics I have and info.
The reason I am doing a Quad 4 is that I have 2 1/2 H.O. engines and I want more MPG than the duke has. (I am getting 30MPG now) plus double the HP is not bad either. I also got a whole Quad swap from Fierobsessed (his swap thread can be found here http://www.fiero.nl/forum/A...060811-1-039415.html ) I was going to do a turbo Quad swap back in 2003-2004 but I got my GT and, well, just kept working on that. Now that my GT is turbo charged I figured I would get back to my quad swap in the quest for MPG. And with the clutch going out on my duke I figured "what better time"
I do have to rebuild the quad and use the best parts of the 3 engines I have. I also allready have 2 full gasket sets. Being a quest for MPG means I want to spend as little $$$ as possible on this swap.
I started to tear down the engines 2 days ago and have spent most of my free time working on them so pics may/will come slowly.
So here are some pics to start untill I get more time to post. I am going to be posting TONS of pics as there is not enough Quad 4 swap info on here.




Cleaning up the engine that came out of Fierobsessed's Indy









Lots of close ups of the engine sitting on the cradle, different angles, to make sure I can get it all back together, and to show how everything fits.







Here is the \/ \/ \/ Indy it came out of

I'm with you. That's some nice engine pr0n!

Such a tiny engine for what it can do.

I knew a guy who had a quad four Fiero but I never rode in it. He reported that the power band down low felt exactly like his Duke but as soon as the revs hit 3000 RPM the power came on fast. I don't believe that he was getting better gas mileage than a Duke a something like 35 hwy mpg. I've heard of Duke owners with the 5 speed Isuzu's getting 39 to 40 hwy mpg. Good luck with the swap.

Time for more pics.

More pics before dissambly.








Exhaust, I don't know if I will use it as it is LOUD. Not that I mind loud but I allready have a loud Fiero.



What a great stock manifold.



Water pump is tucked in there good.



This coolent pipe ws moddified for the 84', I will just use a stock un modded one for the 87'
as the heater return ties into the coolent pipe on 87's



Broken wire on the alt I need to fix.



A/C compressor, I will have to make up new A/C lines as you can see the oil filter is in the way of useing stock Fiero lines.





Engine grounds.



The starter is also tucked in there, but at least it is on the intake side.
