Decision help for my Fiero - V6/60.

[caffeine]

Modified wiring and brackets does not have to be a hack job, even if its done yourself. And it's not like they're difficult modifications either. A full 3x00 swap in a Fiero could easily be done in a weekend or two if all parts were collected ahead of time.

Adding nitrous is definitely not stock-looking.

Edit: the OP was originally complaining about the lack of top end power, which several have said could get even worse with iron heads and more displacement.

drilling a new pattern on a bracket is not.

also, he hasn't stated a specific power goal, but it doesn't change the fact that it would be easier to reach on a 3x00.

That poor Fiero... Clearly he doesn't care about his car- he's using a Fram.

which is why I said hidden. its not hard to hide a nitrous kit. Especially since a fiero has a huge intake tube and filter canistor. Not hard to hide it at all.

With the high-grade of todays morons, I don't think it's a joke...

Like I said before, poor Fiero....

No one saw mine on my 3400 engine till I pointed it out... Obviously now with the direct port system I'm making that's just impossible to hide... lol Unless I get all new nozzles that will fit under the plenum... lol

the fuel rails will make that damn near impossible...

Where can you hide the nitrous bottle though? I'm not sure my bottle would fit in the front compartment even.

[3400-95-Modified]

the fuel rails will make that damn near impossible...

1" plenum spacers open up a lot of space under there...

and yeah with a Fiero I guess hiding the bottle is a bit harder... mine was just in the trunk.

I was going to do the same on my 3500, but the 3/4" spacer still didn't alot enough room over the rails, and put the UIM in the decklid...

[3400-95-Modified]

Yeah I still don't know for sure if my hood is going to clear the 3100 plenum... I'm hoping it will. If it doesn't, I do have some wiggle room in the spacers that I could machine off to make clearance... but I have to watch everything else to make sure the nozzles don't run into something.

Please listen to these guys on here they are right !! I have a 86 z24 that had a iron head 2.8 in it , extremely similar to your fiero. The 2.8 blew a head gasket and I feel it's just as easy to pull the motor,i did. Just happened to find a 3.4 from a firebird at same time. I got it for 50 bucks! I asked questons on here & pennocks and read every thread i could read .Well here's the point,EVERYONE told me to skip the 3.4 & just swap in a 3400.I didn't and went the easy & cheap route. 1- it was easy 2- looks completely stock 3- does have gobs more low end torque. Even though it is quicker, it's not that much . Would Ido it again? Absolutely NOT!!! And when I done swapping a 3400/282 into my 93 gr am I'm tearing the Z back apart & dropping in 3400/3500 hybrid. Whatever time @ money it takes extra WILL BE WORTH IT! A car that's fun to drive and doesn't fall on it's face is great!!

This topic is going good but haven't seen any posts from the creator 82-T/A since the first page. Guessing after reading all the opinions and advice, he's either scared of the idea now or seriously thinking it over.

My personal experince, I've done stock 3400 swaps, 3400 with Fiero timing cover & accessories, & helped out with a 3.4L swaps (one currently in progress). If 82-T/A is looking to get more HP but keep the stock look, I'd find a F-body 3.4L engine to start off with. By the time you finished modding the 3400 block to except the 2.8L heads, you HP will drop enough to be comparable with the 3.4L block. Fiero intake is 52mm?? I think, but the intake bottle necks to 43mm before opening up again. It will be alot easier to install, most complicated part would be drill new holes in the block to relocate the started to the other side for Fiero use and Rodney Dickman sells a kit to help out those who need the help. I'd say there are a few more choices & places where you can by a cam for the 3.4L, though the 3x00 is becoming more available. I had my stock 2.8L cam regrind to match close to the comp cam 262 & still use stock pushrods. I have a friend building a 3.4L for his Fiero just for the sake of looking stock & little more HP. It is the best way to go for stock look, but if you want more power, boost it after or go with a bigger motor all together.

2nd 3400 we did, an 87 Fiero timing cover & accessories was used to keep a stock look (87/88 timing cover can only work for this mod). Mods to the timing cover & dog bone bracket was needed to make it work. It's probably the closet I've seen to a motor swap that almost looks stock.




First swap we did, I left the motor completely stock, OBD1 computer and it dyno'd 175hp, 206 ft lbs at the wheels. On the highway I was getting 6-7L / 100kms (not so much now after modding the motor but still under 10/100km) one thing with this swap, do NOT use the stock Fiero air intake canister, build a 3" tub & put a cone in the fender well. That stock air intake set-up starves the motor. After doing my mods to the motor & installing it in another Fiero temporary, I put the stock system on and it dyno'd 160hp at the wheels Took it off the next day & installed the cold air intake. Motor's back in the proper car again, but hasn't been dyno'd since.

My current set-up



Hoping all the info in this 5 page thread helps you out 82-T/A, in the end it comes down to your own decision what you want to do. I've got a completely stock low milage 4.5L Allante V8 sitting on a dolly waiting patiently to go into a Fiero one day. I know I can get a lot more power out of a 3x00 swap, but it's the idea I have in my head that I want to build it one day. Guess you can say it would be more for show then go, but still a hell of a lot more go then the 2.8L.
