Can I jump on here also.

I'm doing a 3.4OHV implant.
Wondered what MPG change I might exspect from moving from the shot 2.8.
Any info there is on what to change in the prom or a copy of a bin for a 3.4OHV

can't help you on all of them but 3.4 dohc 91-93 200 hp@5500 200ft lb @4000 94-95 210/210 96-97 215/215
2.8 120 i think

quad4 lo version??? HOversion 170hp i think and w41 version 190hp.

3.4 ohv is hovering around 160 i believe.

i do not have any swap experience but easiest/cheapest to best power would probably be the 3.4 ohv. don't know if you can tell by the amount of information but the lq1 3.4 dohc is what i would prefer.

p.s. mileage also depends on what tranny you are using too.

it's dohcfiend my knowlege is limited but i believe there is quite a bit for it as it is a kissing cousin of the 2.8. not sure what the n/a record is but i would say you could proably coax 185 out of it without really going into the motor. this is assuming you start with the 160 hp version.

The aftermarket for the 3.4L pushrod is average. There are a decent choice of camshafts and valve train components, two aftermarket intake manifolds, (One is for a carb and the other is EFI.) Pistons need to be custom but are available.

Given the available parts, You could build a 3.4L pushrod up to have around 225hp normally aspirated and possible closer to 300hp with forced induction or NOS. Although there are aftermarket parts available to build up a 3.4L, They can get pricey. Aftermarket headers and performance manifolds run about $500 and up. The aftermarket EFI intake is about $600 and the carb'd intake with the 4-bbl carb and mechanical distributor (required) would cost about the same.

I built a 3.4L with a 4-bbl carb and it had about 230hp. It was fun, but a year later I pulled it out and went to a V-8. (my budget grew very large so I was able to do the V-8 swap where before, The 3.4L was a lot easier to do on the smaller budget.)
I sold the 3.4L to another member who has been enjoying it for over 3000 miles now.

My advice to anyone looking at engine swaps is to first determine your budget, how much power you want, and how the car will be driven. Then look for an engine swap that fits. The thing is a Fiero is a very versitile chassis and so far almost every GM engine has been put into one. I also would recommend looking locally for Fiero's with engine swaps and getting rides in their cars. Each engine style/swap has a different "feel" to it. So if your looking for a huge low end torque monster a V-8 might be a better choice for you, on the other hand a high reving 3.4L DOHC might be more to your liking. Your preference on how you want the car to act is a big factor on which swap you want to go with. There is no "best" swap as each person has their own preferences.

Building a 3.4L pushrod with all the aftermarket parts might cost the same or slightly more than just dropping in a 3.4L DOHC and you'd be at about the same power or installing a 3800 supecharged engine might cost a little more but you get a 50-70hp increase. The 3800SC engine has been getting into the 30 mpg range so that may also have an effect on which engine you decide on.

good suggestion oreif. i totally forgot about the l67. which has a very large aftermarket following. also if you can afford it speed is very good for these too. 13.1 bone stock i hear.
