i have a 87 turbo supra and i wanted to do a 1j swap on it but also was (thinking it would be cool to have a rhd mk3 supra). if i got a jza70 front clip could i just transfer over the wiring n engine or is there still a headache involved n doing a rhd swap plus 1j swap?

anyone who has done a rhd swap plz give me ur input.

Knew a kid in Arizona with an R32, he had to go through drive-throughs in reverse if he was alone...

On the original subject, I really hate to deter people from their dreams, but if you're even asking a question like this, "headache" is just the start of the long list of words you'd end up learning. ;)

I would say that if that's what you want to do then go for it. How ever there are options for how to go about getting a RHD MK3. You could buy all the parts needed and mod a LHD car to be RHD. You could buy a RHD front cut and strip both the the front cut and your supra down and cut out the fire wall from the LHD car and weld in the RHD fire wall. This would make installing the RHD parts much simpler as it would be like working on a "factory" RHD supra. You could also buy a RHD shell and save your self the trouble of converting the LHD shell. There was some one on this forum selling a RHD supra in Florida a few months back. Depending on how much of the work you can do your self will change the cost of each option. If you are a topnotch welder and are very good at both body work and automotive wiring then the welding on a front cut would probably be the cheapest option. However if you plan on paying a shop to do all the work for you then it might be cheaper to just find a RHD shell. No matter how you do it you should probably plan on spending at least $5000 on just having a RHD car.

$5000? I'd say that's a generously low estimate. Maybe if one were at the right place, right time, and already have ALL the tools and experience needed.... I mean a clip is going to cost you MINIMUM $2000. If you intend to have a shop do something like this, I'd say you're looking at least 100+ hours worth of time put into it to make it right. Considering most shops charge anywhere from $80-100/hour, that would add up FAST.

Better off finding a RHD car and finding a way to make it legal where you live. In Nazifornia? Good luck with that.

Holes have to be cut. Steering rack has to be changed. Dash and wiring have to be changed. Too much work for no gain.

Complete rebuild of the unibody... Not worth it.

Some cars it's easy as they share the same firewall for RHD and LHD, but not our car...

i say do it. you could probably import a shell and piece it together as a kit car and "probably" be able to register it. or if you have the skills doing the firewall swap would be your best bet as far as making it street legal. its been done alot with hondas

I helped a friend do this some years ago. It was not bad and the whole process took approximately 3 days. That was 3 days after we had all the parts from a JDM RHD car. The car was stripped down to a shell and all the wiring replaced, the firewall was cut out at the welds and the new one was welded in. We had to make a new mounting point for the accelerator as it was nowoutside of the firewall area that was replaced. Really it was not all that hard and the cost was maybe $5k when it was all said and done but that included the motor and trans. There were still pics on sf.com last I saw. Unless you have a contact in japan that can strip a RHD car then this would be an expensive and timely endeavor and with the exchange rate what it is now all parts prices form Japan have doubled since we did this.

Like I said alot depends on on how much you can do your self. However as other have mentioned where you live also has alot to do with how difficult this kind of thing is to do. I am lucky as where I live on a car as old as a mk3 supra you only need "A cleen title" to get it registered and some one to look at the car in the parking lot of there garage, kick the tires have you flash the lights and turn signals to get inspected. I often have to ask to have it looked over any more closely than that and then they just tell me if they found any problems, stick a sticker on and I pay and go. I know of more that one person around me who realized that as far as any one cares there no real difference between a JDM or euro car with a couple of key bits swaped on from a USDM rust bucket in a afternoon and spending big money and tons of time cuting up a JDM car and replaceing 90% of a USDM cars parts.
As an example let's use a RHD MK3 supra. There are USDM MK3 supras and where I live you can have a RHD car. So you buy a nice cleen usdm shell and a complete JDM parts car. You then strip them both down and weld the fire wall from RHD to LHD shell. You swap the dash and because the JDM cars interor is mint you swap the doors and complete interor. Then you swap the hood and hatch because they are in better shape. Then the shell get media blasted and painted a non factory color. Then you swap all the harness, both the engine and body and the JZ subframe and engine get swaped in. You happen to like the 89+ body so you swap the front bumper and front and rear lights. The brakes are replaced with willwoods and the suspention with coilovers and other after market parts. You go single turbo and are running on stand alone engine management. SO... what is realy left of the USDM LHD car? Not much, just a bit of unidentifiable sheet metal, and the car your left with has no matching vin tags to the title and has a weeker frame due to being cut and welded. So why bother if the car is FOR YOU? Buy a JDM car and a USDM rust bucket and behold, was that not the fastest and cleenst JDM swap your buddys have ever seen, it looks so cleen they would sware its a JDM car. Through any good parts from the USDM car in you shed so you can always say "look hear are the parts left from the swap". Rent a chop saw and cut up the useless rusted out USDM shell into small pieces and make a run to the metal scrap yard and get a few hundred bucks back. This car is safer due to not have to been welded back togeather and as long as ITS ONLY FOR YOU and you don't lie and try to sell it as something its not your fine. Don't try to say your new R34 skyline was your old Maxima, it wont work. But your Mistubishi GTO could have been your old 3000GT, get it. Wink Wink

This will not work every where and don't be a stupid dick and start selling JDM converted cars on ebay. This is a little loop hole that might help you to get the car you have wanted for years for your own enjoyment. And if you do this and do something sutpid and it blows up in your face don't blame me for it, I am just posting info I have learned from people I know. This is also helpfull if you are buying a suposidly legaly Inported JDM car as it would be something to watch out for so you don't pay big bucks for something you may or may not be able to use.

it can be done, but for the cost, would be cheaper to sell your LHD supra and buy a RHD by the time its all said and done. bout only think you will be able to use from your LHD dash is the ashtray...........

I did it in my spare time and it took me about a year to get it all correct (still a work in progress). It cost me about 5k and I did all the welding myself. My LHD car I got for dirt cheap with minor issues and a blown engine. I got the front clip from a guy in Miami on a deal because he wanted it out of his yard. There are still a lot of things to consider... . You won't be able to use your LHD wipers, so you will have to drill out approximately 100-150 spot welds on each cowl and then reweld them in after taking the glass out. You don't have to do anything to the unibody as it already has the indentations for the steering column in the engine bay. You will need the RHD crossmember, steering rack, front body harness and inside fuse/ relay boxes (both sides), and depending on if you want A/C you will need to be able to salvage the RHD air box from behind the dash. I'm not trying to condone doing this, just saying there is a lot of work involved. The wiring side of things has gotten a lot better since 05/06 when I did mine so you shouldn't have a lot of issues locating what you need to get the car running as long as you have the patience to sit at the computer and SEARCH for it and not just post a question on here like you are the only one with this problem... But if you are going to do it remember once you start cutting, you are past the point of no return. Good luck!

You know, I kind of want to do this to my car, the wipers on our cars wipe a part of the window that I never look through (the top) but leaves the bottom half dirty still. The passenger side, oh so clear... I wish the blades were flipped.

I know that we did not do this. The firewall swap facilitated the mounting of the wiper motor and it was just a matter of attaching the linkage to the RHD wipers. I just saw the car again on Friday and I know that the only part welded in was the RHD firewall. I can appreciate the time it would take if you did not have all the parts from a RHD vehicle and were piecing things together. My hats off to you because I know it would have been ten times more difficult if we did not have the RHD wiring to drop into the LHD chassis.

Would it not make more sense to just buy a jdm car by way of Canada? I have heard of people doing this, its a car landed in Canada, already has a north american VIN and then u just import from Canada. You could get a whole running car for less then chainsawing up your car to get something close.

I am all for cool ideas, but one also has to factor in the high cost and PITA factor.

I'm not sure how you did this without cutting into the cowl as the wiper motor is bolted to the cowl right above where the LHD brake booster is, hence the reason for removing the cowl. Wasn't easy for sure... And honestly I only took it out of the RHD vehicle and didn't install it in the other as I was planning on moving to Florida and didn't have to deal with anything more than rain at times. Plus, I am not really a big fan of driving in the rain so if it is raining too hard I just jump in my truck.

You might have got me there. My recollection of events might be too foggy. I didn't do all the fab and the swap took less then a week about 6 years ago so I apologize. I know that the firewall was removed below the pinch weld so I guess I shouldn't speak with so much confidence on the subject. From all the work it seems it would take to complete I am almost positive we didn't do it this way though.
