Has anyone seen the dedicated turbo kit on E bay? says that it is made for the Fiero V6( not universal) I was looking for HP, but have no idea how to do a universal kit........... Price is a grand and change, comments from the knowledgeable people here would be appreciated!
Took a quick peek I don't see any kits as you describe. All need exhaust work/crossover/turbo mount fabricated and seem to have mostly cheap korean stuff provided?
But a link would help, maybe I missed the kit you speak of.
Listed as -pontiac fiero turbo system Description is follows
this is for a new custom turbo system for the 2.8 pontiac fiero it is a direct fit with everything you need to install it will also fit the 3.4
also if you want any part upgraded just ask i can replace any turbo with gerrett or turbonetics same as wastegate for an additional cost
kit comes with
t3/t4 hybrid turbo
custom header
8# internal wastegate
oil lines
downpipe
turbo specs are as follows
Stage-III Turbo Oil Cooled Only! Standard T3 4 Bolt Inlet Flange, Designed to fit most Aftermarket Mainfolds and OEM T3 Manifolds. 5psi to 20 Psi Peak Power Performance Output Capability Designed with a Standard 5 bolt T3 Flange Includes internal wastegate port (optional for use) Compressor Specs : 3" Compressor Inlet 2.130" Inducer 2.755" Major 2" Compressor Outlet T04B/T4 Type Compressor Housing Compressor .49 A.R. Compressor .50 Trim 8 Blade Type T4 Compressor Wheel Turbine Specs : T3 Type Turbine flange T3 5 bolt flange Turbine .63 A.R. 2.205" Minor and 2.570" Major Propellar T3 Turbine Housing 2.274" Outlet 12 Blade Type Turbine
Well I looked all of the info links and still have no idea .............. lots of discussion on whats in the kit and what isn't, did the individual from the forum ever post his results with the kit and was it any good?
I'm skeptical of doing a turbo without making changes to the ECM. The 1227170 ECM used on the 86-88 V6 cars doesn't support a knock sensor, so that rules it out IMO. I think the 1985 V6 ECM does support knock sensor but the factory didn't utilize it. Don't know if either of them has any issues with a 2-bar MAP sensor that a turbo tune would require.
I don't know which ECMs are best suited to a turbo, but a turbo build should probably upgrade it to something from the early 90s that has more speed, resolution, feature support, and present-day internet tuning knowledge than either of the stock Fiero ECMs. There was a Sunbird Turbo (4cyl) of course. No idea how suitable it would be, but I'm guessing a later ECM would be better.
Doesn't look like the kit mentions injectors - stock ones won't flow enough.

Since I am getting no where with this, how about High Performance Intake Manifold west coast Fiero's. As to the turbo..... one of the members supposedly bought one, and I am assuming that he installed it what was the outcome!

I am familiar with the guy that installed that kit. The results were not satisfactory but f he sees this I will allow him to speak for himself.

"My eBay turbo update. It's been about 10 months since I purchased the turbo kit and although it had issues it did work, and it made a difference in power but it wasn't perfect. It lacked the power it should have been producing, it had way to much lag and the turbo wasn't balanced properly and caused a minor vibration. For most normal people it would have been fine but I'm far from normal, a perfectionist with a little OCD, long story short... Every piece of the eBay kit is now in the garbage, I purchased a Precision 58mm billet Turbo and wastegate and had it installed on new improved header pipe and 3" V band stainless exhaust all custom made by AMS Autowerks here in NJ. Along with the meth kit it's now dialed up to 10psi and the boost is immediate, it feels smooth and strong and sounds even better then before. In short, you get what you pay for."
but that doesnt include all the tuning and working with the guy to get it right, also in that thread a guy said his came dented and damaged and was waiting a year for replacement. i thought about it myself but it doesnt seem worth it, better to scavenge a junk yard i guess.
For anyone wishing to add a turbo to their 2.8L or 3.4L P/R engine Fiero be advised that you will need a re-scaled timing table in the ECM and some new power enrichment settings to get it to work properly. Its a tricky tuning process that few have perfected. It's much easier to do this on an a PCM with an OBD II program already set up for boost. Bolting on a turbo kit for more horsepower is just not the answer. The tuning is critical.

That's the approach many here took, working with OE used parts you at least have the advantage of starting with quality and durability. Without explicit details and some proof, anything goes on ebay. I take it he has a manual shift car because there's no way a stock Fiero 3 speed auto is going to hold up to that power increase, at least mine never did beyond 2nd gear.
I cobbled together a T3 from a 1983 Ford Turbocoupe on a custom crossover manifold. The engine is controlled by a 7730 ECM running code59 with a 3 bar MAP sensor. Amazing power but as Joseph experienced it trashed my TH125c quickly.
I wouldn't trust Ebay with anything. Everything I purchased for my build turned out to be junk. Fuel pressure regulators, blow off valves, etc. Buy name brand and don't cheap out like I did. You end up paying twice as much.
