sort of engine swap

[68cougar]

I am picking up a 84 bronco ii this weekend with blown head gaskets on the 2.8. i also have a lead on a 1990 2.9. i was wondering if i can put in the 2.9 and just swap over the intake and various stuff from the 2.8 to the 2.9 or is it too different of an animal?

One is carbed, the other Fuel injected (all 2.9s are FI)

So Im not thinking there is much you can swap. This actually just came up a few weeks ago, try using the search you might find it

Nope. Won't work.


I must be in a good mood today. I didn't mention "search" in this post.... Damnit. Now I did.

I know one is carbed the other fuel injected. I was wondering if I could use various parts off the 2.8 like intake exhaust off the 2.8 to the 2.9. I did use the search feature, I always do hence the low post count. I always try to look up the answers to my questions before I ask, but when I look up on my phone it looks on the internet not in here.

Carbed and FI have entirely different intakes... As one doesn't have a carb sitting ontop of your engine.

Exhaust is probably different, because the engineers would design what works good for the engine then make exhaust to fit, not the other way around I would think.

They are not the same engine family, no you can't do that. There are a few similarities ( trans bolt pattern ) but not what you want to do.

Thanks for the info guys.

I should also mention the exhaust manifolds are very different. The only way one could get a 2.9 to work where a 2.8 once was, is to get a MegaSquirt ECU and a harness from DIY Autotune. At least that is what I would do. I would do it to my 2.3 in my '86 except for one small matter, money. Otherwise, I would MegaSquirt all my vehicles. Tune it up from any laptop.

<edit> I forgot to mention get the 2.9 "Y" pipe for the exhaust. </edit>

I would never waste my time and money on a megasquirt for a 2.9L. I would just throw a stock harness and computer on it. (and call it the scrap guy to come haul it away. )

If you get a 2.9 harness and ECU, you can bolt it in and go.
