im doing up my 76 320. im looking at 250 - 300rwkw.
this is going to be a track/road car.
the plan is...
around 400 - 500 hp under the bonnet.
move the motor as far back as possable
convert to manual
coil over suspention
slicks for the track work.
keep the 2L 4 cyl
what i want to know is...
which diff is going to fit in the cradle, and hold up to the punishment.
which box should i use.
i have the injected head on the carby bottem end, and i want to switch to a twin cam head, which one?
any suggestions for turbo sizing.
i have had a rethink. i know this wont go down to well.
Im going to put a 13bT under the bonnet, with a FC3S 5 speed.
i just need help with the diff, the only ideas i have is trying to adapt a R32 rear cradle to fit, or a 9". i want to keep the IRS though.
sorry i cant offer any info but are you sure you want to go rotary? In my years of road race and Auto X i have found the rotaries always had issues especialy when modified...just a thought i think you were on the right road with the 2 liter
