Hi all, I want to drop anywhere from 300 to 400RWHP in my 84 T.A but before I do this I want to know what the weak areas are of these cars (Where I will need to reinforce) Im good with welding and I also know someone who owns a car hoist so I can get under it easly.
Thanks in advance for any help!

 

Get subframe connectors.

 

where from and what do they do?

Is it posible to fab up something to go in there place since I live in Australia aftermarket parts for these cars is a IMPORT ONLY kinda thing and id have to pay big $$$ to get them.

 

yup do a search for homemade sfc's

 

Thanks, I just had a quick look.

 

Other common things are strut tower braces and steering braces. You can probably find a ton of pictures of strut tower braces on here, I'm not sure if you'll find any pictures of steering braces. They should be easy enough to fab up though.

 

You could fab up some sfc's with some 2 inch square tubing, hooking together the front and rear subframes. You may have to bend it some if you don't want to cut the floor for a straight shot through. You can weld the stock lower contol arms up into a solid box. A brace joining the front fenders together shouldn't be hard to work up. Also, adding poly bushings in place of the stock rubber bushings can add more responsiveness to the chassis at the expense of noise, vibration and harshness.

 

I have picked up a set of SFC's from someone here is Aus (yankeecarman from www.camaro-firebird.org) and im going over the body atm while the car is striped, Im replacing almost all of the firewall/drain area because of rust (from the RHD conversion). I have pictures on my www.84transamresto.blogspot.com sight.
Here is a pic of the SFC's

those look pretty slick!

 

Yeah they are very well made and bloody solid.

 

haha those SFC's could probably handle jet engine LOL dam .... But will the rocker ground effects cover them.

 

Any ground-clearance issues?

I don't know about the ground clearance with them installed, There is a Turbo Camaro owned by Droopz from Aus and he is using the same SFC's.

I havent heard any problems from him regarding to body twist or ground clearance tho.

 

Venom, those are some bad *** SFC. Yankeeman must have his hands full. What was the cost? Is there another way to get ahold of him aside from signing up for a membership at another site. I wonder if he would ship to the US.

 

There is a link under the picture (above) but here it is:

and here is his E-mail:
yankeecarman@yahoo.com.au
he will be able to give you all the info you need.

EDIT: cost was $400AUD+Shipping ($348.84USD).
Im droping an easy 400HP+ infront of my trans and i want to know the body will take a fue hard launches without twisting (more power to the ground) and these look like they will give the car what it needs to do this.

 

Hey I found somthing interesting while cleaning out the floor pan for a respray.
I removed all the body sealer (black) stuff that looks to be from the factory and i found a 3 to 4mm gap betwene the floor pan and the box frame under the door it looks only be joined where the seat rails go across from the center console, Is this ment to be there or not?
If it is normal it is no wonder these things twist so mutch when you put abit of power in them. Im going to get about 3 pieces of 1mm sheet metal @ 150x50mm slightly bent and weld it in over the gap on eatch side of the car to fix the floor to the outer frame for more stringth.
