I have a 98 275 hp n* and transaxle for my 88 fiero. Design 1 sells a kit for $5000. Is there anything or anyone cheaper to do the install? Also looking for help on the computer and wiring harness.

Please... for the love of BREAD... Don't give design 1 your money! You can easily do it yourself for a lot less than that. I assume you are using the getrag 5 speed? There are a lot of writeups on this. Computer and wiring harness can either be stock ECM/diy harness (there isn't much "documentation" per se, but lots of people have done it, so you have plenty of references), Holley commander 950 (plug and play for $1500), and the Link ECM ($1300, you build the harness yourself).

Here's some links:

all have good info, use what you can. I'm sure Fiero STS can point you in the right direction if you choose to go with the stock ECM.

p.s. - sign up on fiero.nl ... you'll probably get more help there ;)
p.p.s. - nevermind the ".nl"... there's only one guy from the netherlands, the rest of us are from the US :p we're over 10,000 members now.

I'm in California and I don't think a five speed N* will be smog certifiable. I know that the auto adds 200 lbs to the conversion, but would be able to handle more hp if I modify the N* in the future. Yes I think $5000 is a lot for a kit to install an engine trans package that I bought for $1100, but it does look like a very complete kit and they did do the engineering. I'm hoping to find a kit that someone else bought and then changed their minds on, or some other more economical solution

In one of those threads I posted is my complete rundown (well... just about) for an auto install. I'd recommend sticking with the stock ecm then, you'll save about a thousand bucks, and be able to control your tranny. If you have the tools (like a welder, angle grinder, maybe a sawzall... you can put it together for about $2700 if you already have the engine and trans. I can guarantee you're not going to find a person who's given up the design 1 kit... If they bought it, it's probably going in. Although, there was a guy on fiero.nl who was selling his northstar project. I don't think he sold it... name was like seebee or something.
