BMW build

[vince]

Last week i picked up ( from ebay ) a modified Haynes chassis powder coated in KTM orange , it has been modified to take a BMW 18i engine with a five speed Getrag gearbox to a BMW diff with IRS , the hubs and brakes are also BMW units utilising a five bolt fitting ,

it came with a standard ford steering rack which i have refurbished and reassembled ,

the engine is full FI , but i'm thinning of converting to carburettors from a CBR600 or something similar , my only issue is the HT coil distribution , so at the moment, the FI is intact , more research required.......

anyone else have a Bimmer powered car ?

Why do you want to put it on carbs?

with the bits that came with the chassis , i have mocked things up to check for fit, and to get the prop shaft measured

the engine fits quite nice

and the manual 5 speed box is also a good fit,

i hope no one can see anything drastic with the setup


as for carbs, well , it would be a challenge, but thats what i like, and it would also do away with a lot of electronics, and give a little more BHP i'm told ?? but sorting the HT distribution will be the worst part ?

the original builder had different plans for the steering rack mount, so for now its not fitted , but i may well stick with the normal mounting method

i also bought a set of new wheels today , BMW of course,

Carbs may give a little more BHP,

But may also give lots less, run badly, use more fuel, be less driveable, harder to start.

You sill still need a ignition control system as well.


I would only consider it if.

1) Going from a single carb
or
2) The stock ecu setup has a complex imobaliser.
