1976 320 A

[tlmitf]

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
half cage
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.


my builder is a pro but i need this kinda info.

thanks for the help.

bump. Can anyone help me with anything? its the small things that bring you undone in the end. any comments helpful or otherwise are greatfully accepted

[tlmitf]

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

[tlmitf]

the rotory will help with the weight distribution, and the builder im going to use has build both N/A and turbo race motor berfore.

this guy has made motors that run more than 100,000 HARD kilometers without many problems, just the usual issues associated with racing cars.

if he is so bad ass then why doent he know what diff to use and why are you putting a non-BMW motor in this thing. Are you really doing any of this stuff or tryin to sound bad for the guys on here?
