1JZ Swap... right hand drive conversion?
 

Well I have made my desicion and I decided that this summer the supra is gonna get the 1jz. I however have read that you need to lengthen the wiring harness by 3 feet. I realized that if I buy a front clip I basically have the resources to swap the motor and do a full RHD conversion. This would also eliminate having to lengthen the harness. Do you guys think that I should lengthen the harness or just convert to RHD? I mean it should be fairly simple. The only difficulty would be drilling the new holes for the steering and the pedals. Let me know what you guys think.

:umno: OR :bow: -------> RHD 1jz ??

Anyone?? How hard is it to do a right hand drive swap. Wouldnt it be better to just do the RHD swap then to cut and mess with the harness?

yeah it probably would be easier to buy a front clip then having to cut the harness.

i know... you should just buy a rhd 1jz powered supie! man id love to have a rhd car but to convert mine one would be way to difficult for me to do... id say just lengthen the harness if you are set on doing it

Sadly, there is a lot more difficult tasks than just drilling new holes for the steering and pedals.

For one, you need to swap out the RHD rack and pinion for the steering, you'll need to drill new holes for the brake master cylinder, brake booster, and clutch master cylinder, redo the door harnesses if you want the master window switch on your side, drill holes for the ebrake and cable, change the center console out, drill new holes for the dash board, and put another dashboard in. Thats just a rough list. It's not even the correct way. The correct way is to cut off the firewall and weld in the RHD firewall.

isnt it illegal to have a rhd vehicle here
cuz all rhd imports from japan have top be converted to lhd

Legal...
 

I dont think its ilegal... And if it is, then pull me over.. I dont care. I just rather have to convert to RHD instead of messing with the harness.

its not illegal... look at all the rhd cars that have tags... skylines, imported supras, etc...

im not tryin to be a smart ass here
but a friend of mine imported a skyline here
and thety made him convert it into a rhd b4 he could even get it licensed
and legalized

im not an expert when it comes to car beaurocracy but
i have seen rhd vehicles with tags
but i know it cost a crap load more money to get it

my opinion:
check state laws first
see how much to convert it into a rhd
what it needs to get legalized

see how much to extend the harneses

and see which one is more cost-effective

probly depends on states and everything but when the car comes over you need to get the emissions changed over so that is street legal but i dont think they can make you convert your car to lhd if the car was manufactured that way? then again im not the smartest person when it comes to cars and emissions seeing how my car hasnt been inspected sence last year in jan! lol

oh, they made him convert his r34 to a lhd vehicle

That sucks but truthfully i would just like to drive one lol not own one and i think i would just extend your harness for the 1jz probly the easyest way to go.

no man, i said this b4 , what sucks is the fact that he never let me drive it not even once
sure i got somewhat a lot of speeding tickets
thats just proves that i can drive at high speeds right? lol

but idk about the 1jz
yes it might not have the HG problem but

smaller displacement?
then you got the twins, i know its nice to say that u got twin turbo
but is it really worth-it?

i mean u can get the same numbers with the 7mgte anyways
if its done right

I can live with a smaller eninge that pushes 60more hp then the 7mgte there isnt much that could touch it beside what injectors and everthing does that use and is the exhuast on the 1jz 2.5 or a full 3in with high flow cats? that makes a big diff your be at 300hp before you relized it lol

still, witht the money u spend on the ijz putting it in

would be enuff to make a 7mgte run about 400 hps
this is where the $:HP ratio comes into play

The reason for doing the swap...
 

I know its more cost effective to just upgrade the 7m but I at the moment have low compression numbers on all 6 cylinders.. If I wanna do any type of racing im gonna need a better engine or rebuild the one I have. Since I need to replace the one I have, why not just swap in the 1j while im at it?

I have a new question that you guys might be able to help me with. I just found a rust free supra 86.5 n/a. With only 79000 miles on it. Would the 1jz bolt right in to this car? With a 89+ cross member and motor mounts offcourse. Because If this is the case I am not gonna spend the $800 to fix the rusty rear panels on my car... I will just sell it and buy this one. I feel that its a better canidate for the swap... Anways I might have a 89 turbo supra for SALE, with 136,000 miles, 5 speed, interior is almost a 9/10,its got the blue cloth interior. Car runs fine just has that idle issue at times which im going to fix before its sold. If you want to race this thing I suggest you refresh the motor. I drive it 50 miles every day and it runs fine. I would like to get $3000 obo. I havent completely decided on this it will depend on how good this other supra is.

IF YOU WOULD LIKE MORE DETAILS ON CAR PLEASE PM ME AND I WILL BE GLAD TO ANSWER YOU QUESTIONS.

boy, oh boy. if we're going to have a 1JZ vs. 7M "discussion", can we try to keep it knowledgeable?
BICPerformance.com sells 1JZ motor mount adapters for 89- crossmembers, so you can bolt a 1JZ into the 86.5 chassis without problem. If that 86.5 Supra is nicer than yours, then by all means get rid of yours in favor of that chassis.
The problem with converting to RHD is not simply drilling new holes, I wish it was that easy.
Basically, if you have to ask how hard it is, it's too hard.
You're going to need to drill out all the spot welds on the firewall, and transplant the RHD firewall into your LHD chassis.
Its' not easy.
RHD cars aren't illegal, anywhere.
If anyone hassles you, tell them that the car was used as a mail delivery vehicle for a while, and that you bought it second-hand.
Nobody has to know, and nobody has the power to make you change it to LHD.
By all means, check your local laws, but the last time I called my local state police, they had nothing on it. They just wanted to know why I wanted to do such a thing, and a couple of them wanted to see it when I was done... lol
I never did it though. It's not worthit from my POV.

thanks for the info..
 

Thanks for all your input guys. It helped alot. I think I will do the RHD conversion. But have decided to take welding classes first... If I am not ready by summer time I will still do the 1jz swap without the RHD conversion. I will post some pics up for your viewing pleasure if I do attempt it and am succesful. I really dont want to butcher a perfectly good supra so I am gonna learn to weld and do body work first. By the way anyone got a BVSV Charcoal canister sensor?? It has two vaccume lines running to it.. Its close to the front of the car by the intake side. Please let me know if anyone has this! This is whats causing my rough idle at times..

I Would just reccomend buying a RHD supra directly from japan.. after all, it only cost 6.5k for mine landed to my door. lot less hassle, 100% authentic :)

That is where state laws come into play. In Canada it's easy, but in the states, theres a lot more work involved.

I wish I could import...
 

Trust me I already thought about that... But it is very difficult... I would probably spend around 11,000 including car cost to get it here....

in my opinion it would just be easier to extend the wiring harness because if you don't and you go with the front clip there will be welding and drilling and such but if you just lengthen the harness there is only cutting and soddering. i did that with my JDM 7m and i'm not sure about 1Jz but to me it just seems simpler to make it longer

MY car...
 

Anyone interested???

Rhd
 

To do the RHD swap correctly,

Things you will need:
-Half Cut, When looking for one make sure to ask the person you are buying it from to send you pictures of the half cut and dash so you know you are getting one with usable part.
-Door harnesses, switches
-Rear Main Harness, seems like it would be easier to slice the harness, not true, just bye one and you will love yourself for it!
-Center Console
-E-brake and cable.
-everything else is included in most half-cuts

You will need to completely disassemble the entire front half of your car and the entire half-cut all the way down to nothing including the windshield(you will break it) you will also need to take out the seats(fron and rear) and all interior panels so you can access the rear body harness.
Then you will need to start drilling. You will need to drill out something like 200 spot welds(I tried to use a special drill bit but just kept burning it up) some of them will be hard for you to find. You will need to cut out some welds as well. You must do this all around the firewall because you want to take it out as a complete unit. and it will be a pain. be sure to remember what parts you are using... you can hurt the firewall that you are taking out of your car but you do not want to hurt the metal around it. With the Half cut you can hurt all the other metal but you do not want to bend the firewall. When you finally have the firewall out i found that using an engine lift while putting the new one in my car way easier than trying to hold it there while welding.
You must weld everywhere that you cut. Top side and bottom side. then paint and put undercoating on.

then you simply put all the RHDs stuff on and leave the lhd stuff off.

This is a PROJECT!!!! not just something you will do in a day. You will spend hours just drilling hole after hole. you need to be care full not to mix the parts. There will be parts everywhere. If it were not so expensive to import them i would most definitely suggest importing one. But, with that kind of expense if you really want to have one doing the swap is the way to go but just know you are getting yourself into a Ton of work. It will take you longer to do than you thought. and when you are trying to get specific parts from japan it can take months.

Sorry i am kind of a rambler

Way to revive a almost 4 year old thread

Nothing wrong with a bump if you're adding good info.... actually if the thread isn't huge and already full of bad info, it's beneficial as it reduces the amount of weeding through posts someone who is searching will have to do and it reduces the demands on site resources.
