What options do you have to make the stock 4 cylinder fiero at least as fast as a stock v6 fiero.
Are you able to drop any other HO 4 cylinders in the car without chaning the tranny, wiring harness, and the ECM.

How much work is required to drop in a v6 engine from another fiero?

Any bolt on mods such as intake or exhaust to gain enough HP?

You need 140 hp to catch up to the V6's.

There are lots of threads on the forum. Run some searches.

There are guys with Quad 4's, Cosworth Vegas, and Superduty's.

Try searching 2.5 or Duke. You'll come up with a ton.

I could keep up (keep up as opposed to pass up) with the GTs (at the time, very stock before the 3.4s) in my club when I first joined.

A search about them would also have my comments on replacing the starter every 6 months....


...but it was worth it!

Cut the Cat off, K&N filter, Remove the A/C belt, Comp Cam, and Roller Hydrolic Lifters. That will put you over the 140 hp mark and you will out run the stock V6 Fieros. Want to go faster yet. Put on the Holly Throttle body, Get the new Intake Manifold, and header, and Port and Polish. with all that you should find a little over 200 HP, After that it starts to get real expencive.
