I've been doing a lot of research through the archives on PFF, and I'm at a cross roads. I'd like to get more power out of my 3.4PR and I've come to the conclusion:
1. Do I get a trueleo intake (I'm having a hard time finding one, or I miss out on a sale) and do a 7730 + DIS swap; OR 2. Do I CARB it.
If you were to ask me, ....right now, ....to make a choice - I would choose carb. I've never had experience with one, which is why I'm drawn to it. I would like to be unique with this car - there is only one other person I know of (in Ontario) that has a carbed 2.8/3.1/3.4 and that's Arns85GT. From the forum posts in the past, it looks like a very doable swap.
I'm also looking at cleaning up the engine bay - i hate all these vac lines.
I think a turbo would be a great solution to more power. You'd still get good fuel efficiency and you can get a greater range of adaptability for the power level you're looking for. It isn't a very unique solution though.

Good luck!
I have thought of a turbo - it is a good solution, and it's been done before many times on here. I do like the sounds of a turbo too
But it's not unique. When I say unique, this is what i'm talking about:
The Fageol 60 degree supercharger, from searching the forum, tend to starve the 3.4L air-flow at higher rpms - that is OK with me. Most of my driving is around town. I'm not looking for a quarter mile car, I like power in the lower rpms. Plus it requires a carb conversion to work, which is ok with me.
Now finding one is a different story - there is one for sale on the 60degreeV6 forums, but no lower intake to mount to the 3.4L. It would be tough to source one.
It is not a plug-in-play kit, it would require some fabrication. One member on this board has done it in a 88 with a 3.4L - he said it was great. I've tried contacting him to get his thoughts, but no luck
If I were you I would definitely go the carb route. When I was building up my 3.4L (before I decided to go with an L67), I found that the easiest and most affordable (believe it or not) way to make power out of that engine was with a carb setup. Get the Edelbrock lower intake manifold (p/n 3785 & 3789 http://www.edelbrock.com/au...y/performer-v6.shtml ), and a Crower Hi-Draulic Hauler (p/n 03050 http://www.crower.com/chevy...6-hydraulic-cam.html ). There's a few carb options, but it depends on how high you want to rev the engine. If you're not concerned with the upper rpm range (this cam has a 6500 rpm redline), then the Holley 390cfm carb should be fine (p/n 0-8007 http://www.holley.com/0-8007.asp ). If you want to be able to take the engine past 6000 rpm, then you may want something larger, but there are many options. Personally I think that the trueleo intake is a little strange looking sitting in the fiero engine bay, but some people like it. With that setup, if you were to get the heads ported you could definitely see over 200whp. Just something to think about.

I'm still on the fence about it. I've been watching a thread with the eBay turbo setup, and it's sparked my interest in doing a turbo.
I'm kind of partial to the way my engine bay looks now, and I'm hesitant to change it. While I was out doing measurements last night on spacing for a turbo, i took a pic...
Fyi, those blue wire looms are going bye-bye. They were originally installed by the guys who did my car, and they don't match anything. complete eye-sore...
IMO, bright colored wire loom just adds to the visual clutter. Black wire loom should look much better.
Completely agree. With most engine bays, the intake, valve covers and headers should be the center of focus. A blower/supercharger or a turbo helps too....
....I wanted to keep fuel injection, and do the 7730 swap for this below....
It took me quite awhile to find one of these – almost 8 years. Fortunately a local guy in the greater Toronto area had one and the kit only had 1,500km on it.
This is the (now defunct) RSM kit. It includes the bracket, pulleys (plus custom aluminum crank pulley), belt, piping, silicone couplers, blow-off valve, and the supercharger. The main unit is a Vortech V9G.
It is currently setup to produce 10psi of boost – I’m going to dial that down to 6-8psi for longevity of the 3.4L

Sorry, been really busy with work and family time. It's been too cold lately to work in the garage. However I did get around to installing the Fiero Warehouse spoiler I ordered back in October.
Installing this spoiler was pretty straight forward. The instructions were written on it – measurements were made on the deck-lid and a silver sharpie was used to mark the points for drilling.
Once everything was lined up, the deck-lid was sanded down and epoxy was used to secure the spoiler. Heaters were used to help the epoxy cure because the temperature was around freezing.
Don't busy it up with more than 1 tone on the outside. you just unbusied the interior, for goodness sakes.
if I had to choose a color for it, I'd say pearl white, (think caddi white) or the new corvette blue. that would be awesome. but definately don't busy it up with a two tone or something, it's not 1987 anymore

Interesting suggestion about the caddy pearl - i have thought about that before. But gold is the colour of the engine bay, and I would like to continue that theme to the exterior.
I have to disagree with you on not going two-tone because I have the Fiero Warehouse nose. It is inherently "droopy" with a single colour scheme - I have seen Fieros with one colour and I do not like the look at all. The nose looks like it's driving the car into the ground.
FieroX has the same nose and he did a two-tone orange/black paint job - it looks fantastic, ...and it hides the "droopiness".

What do you think?
I went turbo on my 3.4 it woke the engine up. I was running 10psi with no issues. I built a motor to run 18PSI daily but never got it back in the car before I sold the car. Here is a video of the car through 3 gears. Warning I spent 5K on motors and turbo set up doing the work myself to get it right.

I'm working full time and getting my degree (part-time) at the same time. So between family life, ...working, ....putting in a patio and 60ft stone walk-way at the front, ...and schooling over the summer I have been quite busy.
Not much time left over for the Fiero. I have taken her out for a few spins over the summer - but I did not document it here.
But not all is lost:
1) I purchased a lambo door kit (Jesse's version) 2) I have begun testing the paint for the Fiero.
I'm doing it in Rustoleum. Before you start hating, do a search on Google.
Carbon mist metallic and Champagne metallic.
4 coats of colour. 2 clear UV coats. Wet sand. 2 coats clear UV. Wet sand. 1 coat clear. Wet sand. Rubbing. Then polish to a shine.
Sorry everyone, it has been a busy year so far. I've been occupied with a lot of house projects this spring and summer. the winter was so brutal (and long) up here that i didn't have a chance to tackle the car from nov-march.
I'm going to try and work on the Fiero this fall. I have the lambo door conversion, a new set of headlights, and a few fiberglass pieces to install. I want it painted next spring so I can enjoy it for the summer.
I want it back on the road, then I'm tackling the ECM conversion and the supercharger.
Sorry for the lack of updates. I've just had other priorities that keep coming up.
I've contemplated selling the whole project, but I just can't bring myself to do it. i've put too much time into the car.
P.S. - i switch my web server around in November, and I just noticed all the pictures had broken links in my thread. I went back through each page and corrected the pic links.

Just take it easy mate. Myself had the same problems and also feeling guilty that i didn't got around to go further with the build of my fiero. Now, i dont mind people asking why its not finished yet. I see it as a hobby and a hobby may take as long as needed, its a HOBBY. So, from the other side of the pond i wish you the best and just hang it there.
Just saying!
