help! need info on m20 conversion into RHD '02

hi newbie here... (and this site is the best thing ive ever seen in my life i might add...)

i have a beautiful de-rusted and repainted empty engine bay just waiting for my '90m20 2.5litre engine (67k+cam) to be popped in.

but i am unsure of what is the best way to go with brakes given that the existing set up was twin circuit with remote (passenger side of engine bay) boosters (non tii struts).

1. will the engine clear these if i stay with them? will it clear one of them?

2. are the volvo calipers everyone talks about twin circuit? ie. do they have two lines going to them?

3. with the '77 320i vented rotors, should i use just the discs, or the entire hub?

any help would be much appreciated!

anyone else down under attemted/ing this conversion?

Have you checked the clearance between your

steering box and exhaust manifold? This is usually

the limiting factor in RHD engine swaps. It was

one more reason for to get an e21 rack and pinion

conversion for my M2 project.

RE the servos - I've changed mine for the slightly

larger e12 units (more reliable) and mounted them

as close to the chassis rail as possible - M3

engine's considerable air box clears them now, so

I think you should be OK with a bit of jigging about.

Good luck! Nick

hmmm thas a very good point nick, thanks for bringing it up...hehe just one more spanner in the works!!

does anyone have any specific info regarding the m20 straight six and RHD steering setup?

incidently, i do have a complete rack&pinion setup (+new seals) from an e28 323. could this be used if necessary?

baring in mind, ive just rebuilt my steering box and i would rather avoid the extra work if possible.

cheers

Regarding Q2: yes - the girling calipers from 240series volvos for ventilated disks. You'll also need 1977-1982 323i or 1977 320i rotors and 1980-83 318i hubs.

I have spoken to a brake fella about removing the two remote boosters and replacing it with one. He advised me to get a PBR VH44 booster and he can re-plumb the lines.

Thanks a lot for your help.

With regards to the PBR VH44 brake servo; is that a BMW part number?

Cheers

fitted to some OZ cars - or so the brake fella said. I'll try to find out what they are fitted to and let you know.

Cheers

Thanks mac... i should be able to find it, and i think it might be the way to go- free up engine bay space and all that.

thanks for your help
