How much Kg's over stock motor can u go with aftermarket WITHOUT bracing?
This is an expensive question i guess because it would involve consultation with an appropriate engineer.
Its just you see people putting in heavier kombi gearboxes and kombi type 4 motors, which adds extra weight and i don't seem to see any extra bracing
fitted to assist the stock frame horns and what not in taking the load.
I'm just curious and am assuming that perhaps there migjht be some figure's or percentages used in the industry.
Any help is appreciated.
Regards,
Chris.

Chris ,
This will not need any engineering approval , but yes bracing the back end of the rear frame horns is a good idea especially as your car is an offroad
baja.
The easiest and cheapest way to do this on your car would be to run some 50 x 6 mm flat bar full width of your rear parcel compartment floor abve and
below bolted through with some M8 high tensile bolts , from the bottom of said flat bars run some 32mm erw tubing down to the tops of the horns , and
weld in place being carefull not to obstruct any other companent not yet in place .
Finally if it suits also tie these bars into the rear engine cage or mabey even keep them seperate from the upper body and just use the engine cage as
your support base , either way it will help greatly.

Thanks guys,
And thanks Andrew for the great detailed answer. I appreciate that. It would certainly add to the strength, and even if i run a stock 1600 type 1
motor setup, i will consider because the first 67' baja i had only had a 1300cc but still managed to have bent and cracked frame horns.
Thanks heaps.
Chris.
