you should perhaps narrow down what part of it you are looking for help with. all of it or parts. a google search will turn up quite a few threads on how to do it. not sure if I saved any articles or not. I did on a transmission swap.
I did one a few years ago along with a 4T60 swap (highly recommend the 4 speed auto). not a hard swap.
Good point. So I currently have a '88 Formula with 204K on the OD. The car is in fantastic shape. I am looking to restore some reliability in the engine and the 3.4L swap sounds like a home run. Doing some web research I can purchase a 3.4L crate for roughly $1400. I have a friend who is a trained mechanic that will be helping me with the project. Below are a few key questions.
1. I understand the intake will swap over, but there is a performance sacrifice do to restricted air flow?? I would like to retain the stock "FIERO" intake so it appears stock. Perhaps someone can chime in here.
2. What cam options are available?
3. My car features the 5 speed. Again, at 204K a rebuild would be in order. Are parts still available for these trannys?
4. Will the valve train be included in the kit above? It is a bit unclear.
well, first off you've chosen a later model motor which is a good choice but more complicated. The easy swap is a 1993-1995 Camaro or firebird 3.4. that's the one I did, the later 3.4's are a different animal. I'm sure someone will chime in with information about that engine swap.
General Motors made 3 different 3.4 liter V6 engines. The web page in the link doesn't specify which one you're getting.
That said, the easiest one to swap is the Camaro / Firebird version. It's basically an oversized 2.8 V6. And as such, it's almost a drop-in swap. You can read about that here: http://fiero34swap.eleventenths.org/
The other two engines are more involved to swap in, because they're very different from the 2.8 V6.
I am no expert...I swapped in a 3.4 out of a F-body a decade ago....A bit more power but at a lower RPM (This confounds the "Tonda" contingent) which means it is a monster off the line, but it doesn't like to wind up past 5000 with the stock >>Fiero<< intake.....The pinch point is just down-stream of the TB..The neck of the intake is too small just before going into the plenum. I am modding a spare intake with a piece of aluminum tubing that I am about to have welded in.
I have never messed with the cam...In fact I used the stock Fiero Injectors because the ones that were "Recommended" to me would not work properly with my 85 computer- supposedly the 88 computer can run the different injectors.
Get the Ram heavy duty clutch- I ate the stock-size clutch in a few years- And I am easy on clutches!
My 2600 lb 85 SE Getrag 5 spd gets to 60 in 6.5 seconds and thru the 1/4 in around 14.8 seconds...In a parking lot Gymkana it is just about the perfect amount (And delivery) of power.
On the stock intake, do a search for DAWG's INTAKE. Basically he opens ups the choke point and adds a bigger TB. Looks completely stock and provides better airflow for the engine. I have it on mine and it works great.
I didn't keep the 3.4 with 4T60 tranny car long enough to really see how much difference there was since I was able to pick up a 3800SC already swapped car but it was a very nice improvement. sounded nice.
I used a 262 cam (272 requires some machining), Dawg intake modification, 19 lb injectors, bored out TB inlet to match a machined TB done by Steve Monroe. better flowing cat. actually had a truelo intake and exhaust that I had not put on, sold those after I picked up the 3800SC.
I have a vehicle with a 3.4 push rod engine and a 272 cam (no machining that I am aware of) and also used the 19 pound injectors (Ford type). It took a lot of custom tune work to get the engine from pig rich with black smoke and little power to a nicely running vehicle with decent acceleration (0-60 in around 5.4-5.5 seconds). This specific engine has been further modified with a Truelo intake, custom CAI, and large diameter exhaust tubing as well as a turbo. It is a fun car to drive, but I would do another 3800 SC swap before I went the 3,4 turbo ($/HP).
Just finished 3.4 swap too (only need to iron out an exhaust issue) and here is all the link i read up and its a pretty straight forward plug & play. I initially use my stock 2.8 injectors but i was getting lean code even after sealing all the exhaust manifold leaks. Mind you the 2.8 injectors are old so they might not have slight clog/ less flow rate, a rebuild 2.8 injector might work. I went with the BMW #17 injectors instead of the 3.4 injectors since i didn't want it to run rich (california smog). Since i install it, no more lean code. All the links below really help me first time do any swap or taking out the engine. hope this help also from what i read before my swap, that you can't get crate 3.4(F marked engine) anymore but i could be wrong.
Only got about 100mi on it, still need to take it to a muffler shop and have it fix an exhaust issue. Other than that it drive like 2.8 but a bit more torque. Also when buying a re-manufactured engine read the warranty fine print carefully. I spend more time dealing with the warranty on my reman engine (ATK?LKQ reman engine, won't buy from them again, BS warranty) than the swap itself. In the end they claim it was my fault even though the head gasket was leaking before I start the engine. I didn't get a single dime from replacing the leaky head gasket.
