Right hand drive conversion

How difficult/expensive would it be to convert a Q4 155 to right hand drive? I am thinking the 4wd will probably make it go from a difficult to impossible job - but any thoughts??
I like the idea of a Q4, but no chance for a left hand drive on the road (legally) here (New Zealand)....

Re: Right hand drive conversion

wow, what a tough law to have

would be such a big job - not something I would like to do - I guess the steering and interior is a standard swap, but the braking system and clutch hydraulics would be very very hard unless you rigged up a fancy system, a bit like dual controls in a learner drivers car

Re: Right hand drive conversion

Interesting question.... Not based on any knowledge of the floorpan on the LHD Q4...but until someone puts me right, I'd make a guess that the pressings are going to be very similar to the RHD version of the same model year 155...so conversion shouldn't be that difficult. At a guess, if I was doing it, I'd start with the Q4 plus a comparable year model RHD car as a donor for all those odd bits of linkage, trim etc that you'll need. Worst case on the brakes & clutch and you'd have to fit someting like a Tilton (or Wilwood) floor mounted pedal set and re-plumb accordingly.

Like I say, interesting question.

Possibly pertinent is that the RHD conversion for Integrales was always regarded as pretty straightforward apart from sourcing a suitable steering rack. Seem to recall 'people' saying that the feel was never right due to different rack ratio though.

...right, that should stop the web forum from moaning I haven't posted lately.......

Good luck...and go for it!

Re: Right hand drive conversion

Cheers for the comments. As it turns out, you can't import 155 into NZ and drive them on the road. Apparently they are death traps! Japanese imports are OK - go figure!

I think the only way it can be done is to put the Q4 running gear into my "road legal" 155 (which is an 8v). I can see it getting very hard very quickly. Might be a nice hobbie for a few years though!!

I have also the same query regarding rhd conversion. I live in Australia and planning to convert my car into a right hand drive. I think this would be a nice place http://www.americanautomotiveaustral...rsion-process/.

I can't see why it would be all that difficult. If you have a LHD Q4 and you have a RHD 155, then all you have to do.. is put the Q4 mechanicals into the RHD car. The brakes, steering, throttle cables, bonnet catch cable etc. are all going to be in the right place already. The Q4 lump can't be much bigger or clunky than the v6 lump or the diesel that they managed to put in there too... so it'll fit for sure.

The floorpans are going to be identical. On my old 33 P4 the difference was that the propshaft and the 4WD gubbins was in the channel used by the exhaust pipe on the 2WD jobs... so the exhaust had to work its way around it and it was lower than the 2WD... but exhaust is easy.

Rocker on the 16V (longitudinal mount) might foul the brake servo... but the servo is right at the back of the bulkhead, tucked under an indent in the bulkhead..... so it doesn't strike me as being "in the way". It'll be a piece of cake. AR uses a lot of the same parts across the range, let alone across one model..
