So from what I've been reading on the internet....it seemed as if all the 2JZ-GE were High Impedance + Side feed injectors. I pulled off the engine cover today to take a look. It seems like they are top feed?? Anyone more experienced take a look?

I mean they look like top feed to me. If they are in fact top feed...I'm thinking of buying a set of used low impedance top feed 550cc off a US MKIV Supra TT. Then run a resistor pack inline to raise the resistance(not completley sure if I can do that). It's a lot cheaper than buying a new expensive set of injectors

Anyways, here are some pix. Maybe you guys can help me determine if these are top or side feed.

High Impedance, as tested.

Ok, I just talked to my friend with a Mk3 Supra. He just did a 1JZ-GTE swap himself in his garage at home....so he knows a little more about this stuff than me

According to him the MK4 USDM TT's were side feed low imp 550cc. So due to it being side feed, those are no longer an option. He said the later year MK3's were top feed 440cc low imp. These can be bought for about $20 for a set of 6 and sent to RC Engineering to be cleaned/flowtested for about $25 a piece. Only problem is that they are still low impedance, but my friend says some guys just run resistor packs inline to raise the impedance and it works.

The third option he gave me was to use the RX7 injectors. 550cc high impedance top feed injectors. I think this might be my best bet, but it costs about $150 for a set of 6 rather than $20 ok, I'm just being cheap heh. I would also send this set into be cleaned/tested. But does anyone know for sure if the RX7 injectors will drop right in?
