Your welcome. I like the mirrors on your Fiero.

[netjunkkie]

as far as i know they are stock 85 gt mirrors

[badassgremlin]

check ebay if u want u should check places that sell remanufactured engines

[Blue02R6]

I finally found a local place that will sell me a used 3.4 for $1400 or a reman. for $2200. They will do the convesion for $4000+ other parts. Thats more than I paid for my Fiero!

netjunkie your mirrors are painted the body color. Right? They were painted black from the factory, as far as I know.

[netjunkkie]

ya i had them and the mirror control painted same as car

[Blue02R6]

I found a Z34 lumina for $200 but it's in atlanta. They want $800 to ship it back here.

[Blue02R6]

I just thought I'd ask, anyone know what it would take to turbo a 3.4? I'd need a turbo, some custom exhuast and intake work, but what else? And how would i figure out the best turbo to use?

[LoW_KeY]

not sure.. haven't really looked around at DOHC in the fiero I was all set on the L67.. try http://www.dohcfiero.com ??

[Kameo Kid]

Are you still looking for NEW 3.4 DOHC ?? I may know where one is..

[Blue02R6]

Yes, but right now my money is very tight.
