7M-GTE Supra injectors drop-in to the CA

[Wreckless]

Cheers, I'm a Mk3 Supra owner from NM and I've been doing a lot of reading up on the CA18DET to help with a swap for my friend.

I spoke to a couple of you CA18DET guys over AIM (you guys rock) and discovered that MK3 Supra Turbo's (7M-GTE engine) use 440cc top feed oval plug low imp. injectors. According to what I've been able to turn up, this would make them a drop-in upgrade for anyone not wanting to drop $400+ on a set of injectors. 440cc injectors should bring a 4-cyl like the CA to the 300-320 rwhp area safely, a little further if you wanted to push your duty cycle.

I'm not sure if anyone's already discovered this, just thought you might like to know.

Edit: On a side note, the CA18DET also uses the same Fram oil filter as the 7M-GTE, the 3614. Kinda funny

very interesting...

thanks for the info:D

SWEET!!! friend just got a mk3 supra and is getting a 1jz installed... FREE INJECTORS FOR ME!!!!

Good info. I know where there are a couple in junkyards. Hmmm....

[dareo]

that sounds cool, it looks like Supra injectors and a Big T28 would be some low budget 300whp. I might have to do that if i go the cheap route on my CA.

Plus buying a used set of 6 gives you two spares, when the used injectors have problems.

Sweet! Does an upgrade like that require ECU reprogramming?

[Xero]

yes...larger injectors always require an adjustment to the ECU, however the MAF sensor COULD be hacked (use the search function for "hacked MAF" in the KA-T section)

I used MKIII injectors, fit right in, but the plugs are different (re-wire them)

I am going to try to use injectors from a 4g63. They are 450cc. I will let you know if they work.

450cc injectors from a talon are goin into my motor soon as the eproms get here.

i was wondering if it did fit. sorry for bringing up a dead thread, but i've asked on other forums and no one's tried it yet.

[mikesim]

can anyone help me out?

[DSMs_Suck]

are ca stock injectors low or high impedance...

Cause i know the 7M-GTE injectors are the nippon-denso 440cc LOW imp.

CA injectors are 370cc top feed, low impedance.

from what i've read, the GT-R 440cc injectors swap right in without any extra work. but who has a GT-R and doesn't need their injectors?

[DSMs_Suck]

If they are indeed LOW impedance then try turbo 4g63 (DSM) injectors. Those are nippon-denso 440cc low impedance, top feed, with rectangular connectors. Plus a set of those things costs like $50 or so from any DSM guy that is upgrading.

my only issue is on the silvia forums i went on they said the o-rings may be a different size. if they don't fit perfectly, you'll have a leak, or u swap rings. i just wanted to know if anyone's tried it yet. that's all.

I guess i will be the first to try the 4G63 as quite a few people here are selling them, some even complete fuel rail and cut harnesses.

[WeldingHank]

i was under the impression that CA18DET injectors were high-Impedence.

nope.
