how hard would it be to change an 87 camaro sc nose to a 87-92 z28 nose and 91-92 g-fx? and about how much would it cost?

Check out Hot Rod.com. they just printed an article about puting thos G-effects on and convervting the nose. But it was an earlier Z28. If you cant find it hollar back.

Its really easy if you know what you are doing. I've done the swap to my 85 SC a few months back. The pic in my sig has the Z nose on it,but I had the ground effects off at the time.One thing you will have to do is drill holes into your car so they can bolt on.

I have an 85 camaro do i need to replace the front nose and rear bumper in order to put 91-92 GFX's on?

IF you want the whole thing to look right you will need to put a 85 and up Z28,IROC,88 SC,or 89 and up RS nose on the car and a rear bumper from any of those cars. If you leave your 85 SC nose on the car the front of the car wont seem right, the gfx's will be lower than the 85 sc nose. The rear bumper will not meet the rear quarter panel gfx's right. The nose and rear bumpers are a direct bolt in for your car.

Here are a few pics of my friends 86 Camaro,

Nice pics Zepher. I'm wondering what the MK4 Supra in the background is running?

Before the downpipe and exhaust, I ran a 13.22 @ 107mph in the Supra.
Should be mid to low 12's with the exhaust and downpipe and fuel controller. Got 53 RWHP just by tuning the fuel curves on the car, it was running so rich.
303RWHP with downpipe and exhaust.
356RWHP after adding the Apex-i SuperAFC and leaning out the mixture. We were running 16-18psi of boost.
