Wrong. There is no difference between the USDM and JDM injectors nor is there any difference with those from other markets.

Yellow topped injectors are N/A from pre89 model MKIII Supras and Cressidas. Green topped are from Supras sold in '89 and thereafter. The pre89 injectors (yellow are low impedance and require the use of a resistor pack which is found on the drivers side wheel well. 89+ injectors are high impedance. The upside to having pre89 injectors is that the GTE (all years) used low impedance injectors, so, if you're going to add a turbo to your N/A and plan on keeping the N/A electronics you may drop in GTE electronics... no can do if you're 89+.

Sheesh.....

EDIT: also of note is that if your vehicle has one color and the other vehicle has the other the wire harnesses are generally NOT compatible... you'll need to swap your old harness over.

Oop......I stand corrected.

Thanks CRE....

hey so i've had a jdm engine installed by a motor shop here in ottawa and i have some interesting questions, first of the car is a 89(newer style) but the engine that i acquired is from a 91 auto jdm, now it's been running fine until i decided to check up on my vacuum lines, for sum reason my bvsv(whatever that is) is not on my thermostat housing but rather an electronical device is in it's place? all pictures i have ever seen indicate there should be some vacuum lines there, the company custom build a wiring harness for me as it was chopped near the block. but i still have the 89 ecu in the car and as mentioned you guys were talking about the different impedence injectors on each model, is there anyway i can check if my setup is ok. thanks for your time

The JDM 7M's have all the same equipment except they do not have the EGR system (they should have kept it as it creates lower combustion temps and thus you can apply higher boost and advance the timing even further without knock!) and I believe the oil pressure sender is different. If you don't have the BVSV or charcoal canister I highly recommend you repair/restore that system. It serves a few purposes, the pressure regulation helps prevent the fuel pump from caviating (deteriorating) and also from working harder than it needs to.

The sensor locations didn't really change just one spot was added.

Here are most of the ventilation and vacuum hoses; the only ones you probably aren't going to have are the couple used for the EGR system.

EGR; if your EGR system is present you'll see these components and you'll find the vacuum lines in the first diagram above.

If your sensors are in different locations you need to make sure they're all at least on the correct side of the thermostat.

The injector impedence is an N/A only thing... unless you're putting N/A injectors in a GTE it has nothing to do with a GTE their injectors were the same. NOTE: If you are, for some bizarre reason, wanting to install N/A injectors in a GTE you need the YELLOW topped (see: low impedance) injectors.

Post some pictures of the things you have questions about and I'll see if I can be of assistance.

thanks for some of those helpful hints, well all my vacuum lines are hooked up except for in the picture you can see that i dont have a bvsv with two vacuum ports, instead rather it has an electrical plug. the vacuum line has simply been directed to the charcoal canister from the port on the metal line coming out parallel to the intake. could this possibly be because it's a 91 engine? and also i haven't tested the wires but i assume they are operational even considering im using a stock ecu. and i apologize if it's a fuzzy picture shity camera.

also just to note its near the bottom left corner. and ive have the vacuum line unhooked atm. but not to deviate from that too much my turbo shaft snapped leaving the turbine i think(whatever the exhaust side is) freely bobbing around making a wicked noise. basically the internals exploded sending most of my oil and coolant into the exhaust. so far i have rerouted the coolant lines into each other and connected my maf sensor inline to the throttle body directly. it is all running very well except for a minor leak from putting a custom made elbow to route the oil back to the pan. i can beef it up with bigger parts but what i wanted to know is would it be bad if i blocked the turbo oil lines off with a plate. i havent done it cause i figured it would mess up oil delivery and pressure.

The thermostat neck you have installed apperas to be either a pre89 or N/A version (I can't remember which vehicles those were for... The were on ALL 89+ GTEs though, I know that to be a fact); it's hard to tell for sure.. crap angle cut it off i the pic. If so it has only two ports and thus those idiots saw fit to simply delete the BVSV... it's not the cheapest part and it is essential. Running it off straight vacuum will increase the wear of the fuel pump's impellers.

The turbo's oil supply may be capped, plug the drain too. The coolant line MUST continue, don't cap it. Gut the internals of the turbo if you're going to be driving like this for a while, if any small bits were to get sucked into the intake you can do MAJOR damage in less than one second. Fortunately the IC will act as a filter to a digree, but you need to gut the turbo and thoroughly flush the IC and intake piping asap.
