I plan on cramming a 800 horsepower engine into a fiero I know I will have to build a transmission to handle that I am just curious if anyone knows a good way to reinforce the body of the car itself to handle that kind of power I have heard people say it can get a little wiggly around the 350 mark

Could you do us a favor? Stop making new threads about the same subject and ADD to one of your existing posts?
You keep making threads about a fantasy build that may never come to fruition so why not have all the questions in 1 thread?[This message has been edited by IMSA GT (edited 02-19-2025).]

GM designed the space frame for 700 HP.
Add a full cage with front and rear ties, probably needed for class racing anyway.
You'll never get that much power to the ground.

You'll want to define what it is that you want. 800 horsepower is a great number, but is it the number you're interested in, or the performance you're interested in?
Remember that the Fiero w/ a fully loaded V6 is a 2,800 pound car. In 1995-1996, the C4 Corvette weighed about 3,400 pounds and put out 330 horsepower. What I mean is, if you want a LOT of performance, you don't need 800 horsepower... you probably only need like max 500. It has less to do with the frame, and more to do with the fact that it's a really light car and it can be difficult to get the power to the ground.
Being a mid-engined car, it's designed more for handling. But, it's rear wheel drive so when you accelerate hard, the weight will shift to the back giving you better traction. Me personally, I think 800hp is shooting for too much, you won't be able to make use of that much HP. Even the Dodge Hellcat or Wildcat has a difficult time making use of that kind of horsepower, even with traction control (which effectively limits that horsepower until it can maintain traction).

Experiments in even small doses; LSD is an extremely potent mind-altering substance...

Come on, don't be mean guys... we've all been there. None of us were born with all the wisdom of what should be. It's exciting to think about the possibilities. We don't want to be negative... we want to support and help him refine his goals to something that's realistic and results in a happy experience.

From personal experience, I can attest that 400 rwhp is quite a handful in a Fiero.

I bet many members put posters on their bedroom walls as a kid, with stunning hyper-cars and jaw-dropping bikini-cladded supermodels with matching high heels....
However, when moving from childhood into an adult, these fantasies {which were way out of reach} fade; and reality sets in with a more sober, realistic perspective.
Perhaps, Josh86gt is still more in the former, than the latter... [This message has been edited by Vintage-Nut (edited 02-20-2025).]
