jdm 7mgte to U.S. specs

[shaeff]

it's ok. it happens! just keep everything you learn in mind before you post, that's all.

apology accepted.

you need to swap the oil pressure sending unit because the JDM one measures differently than the USDM one. (metric v.s. standard) the EGR is needed to make your car legal for emissions, if they have it in your area. there is no emissions testing where i live, so i get away with no EGR.

which temp sensor are you talking about? the water temp sensor doesn't need to be changed, as the "normal" mark is just half way on the gauge, there's no numbers.

take care,

so your temp & cold start sensors in the thermostat housing don't change in 89?

Hi guys, I'm new to this forum. Lemmie get this straight. Basically in order to do a JDM 7m-gte swap into a USDM chassis you would need: LHD Throttle body, pre '89 ECU, JDM harness, coolant hoses, vacumn lines and misc. sensors? This sounds like a pain in the ass. Mabye I'm uninformed about the JDM 7m-gte or something but, whats so special about the this motor? Wouldn't it be easier to run a USDM engine?
I just recently bought an '88 MK3 roller and the engine is locked up. The guy said it developed a rod knock and eventually spun a bearing. I havn't opened up the engine to have a look yet. I'm considering a new motor and wondering if a JDM would be worthwhile since I may be able to use some parts form my US engine. Sorry to Hijack this thread beear with me guys, I'm 16 and this is my 1st car, I bought it to gain some mechanical experience and have some fun... safely of course. THanks.

no, you'd need the wiring harness and ECU (turbo) that matches the yearspan of your CHASSIS. (87-88 or 89-92) you don't need any sensors if you don't mind splicing on a few different connectors. the "special thing" about the JDM motors is that they SUPPOSEDLY have between 30-40k miles on them. it's really a crapshoot. the ONLY reason i got a JDM engine is because i couldn't find a USDM one.

if you have enough money to buy a JDM engine, then you have almost enough to do a rebuild of the one currently in your car. you never know if the new engine has the same problems as the one you have now. it's a crapshoot. if i were you, i'd rebuild what you have now.

good luck,

thanks for understanding. after my one post i kinda lingered around and was looking at stuff and saw the wealth of knowledge some of the guys here have, and then i read supra centrals post and understood why i was treated the way i was. ill try my best to be up to those standards.

as for the jdm engine, i got one because the head i had was warped and the block looked to be cracked.

upon reading the thread about how to talk to the oldschool fellas i see i may have underminded you guys and apologize. i was being lazy to your standards and also apologize for that. i also apologize for being rude too everyone i was rude to... i only felt i was being picked on but i now see i wasnt. im sure this post wont have another flicker in any of your minds but id just feel better knowing id apoloagize. i am greatful for the help. i have been reading up on the other threads and older threads trying to understand why it is i need to swap the oil pressure sender, egr, temp sensor. thanks again for the help and again im sorry for underminding you, being lazy, and being rude

That's ok man...Shaeff said it all
No harm, no foul...in fact, I think you're showing a lot of character...you are welcome here in my book.

holdon im confused, do i need a new HAC sensor? if im not swapping the ecus and harness do i need to replace the HAC sensor? all i plan on doing is swapping clips off the jdm harness to my 87 harness. thanks guys

if you're running an 89+ ECU, it has an internal HAC, if you're not, then you'll need an HAC sensor.
