SC WTB 440cc injectors for Na-t

I don't agree with the killing the turbo's I've only seen that once.
My 91 aristo made 390 @ the wheels with a full exhaust on stock 440's no FPR/No fuel modifications at all. Plenty rich with ceramic twins @ 18-19 psi for about 5 years and 130,000 KM.
My 93 RHD rz supra made 404 @ the wheels with stock fuel system on 20 PSI for 3 years and 25,000 km until I sized a twin due to no BOV. (25,000 VERY hard KM, lapping the car every Monday for 3 summers)
My 87 supra with swapped 2jz aristo engine makes 430 @ the wheels @ 20 PSI and has been doing so for 5 years 30,000 KM
#1 the ceramics break only through stupidity and going super lean, have only seen one ever broken where the exhaust wheels where somewhere down the downpipe
#2 440's are really only safe to 400 WHP unless you add a FPR and turn up the fuel pressure
#3 Tuning and a wideband is ALWAYS suggested and do not go over about 400 WHP if you don't have a FPR and a supra TT pump or walbro 255
So where does this leave you? If you just want to run a good safe level, buy a modified ECU which add timing/fuel/ rev limit and removes boost cut. Set the boot to about 15 psi and slowly go up watching AF to ensure the computer's got your back.
Generally, I used a Emanage blue or ultimate to add fuel to the aristo ecu easily.
My mk3 is running 550s from a mk4 but since i'm running a e85 blend i'm already out of fuel trying to go any higher.
I do have a set of 440's somewhere i think if you are interested, i also have 3 ecu's 2 stock aristo 1 modified aristo.

Another option is a set of 02-05 Subaru WRX STI light blue injectors ($80-99 for 4).
They are 440cc, high impedence, 11mm, and don't require new connectors. They do require that the spacers be removed from the bolts that hold the fuel rail down.
I have them installed on my GE and am almost done with my GTE ECU swap.
I turned the key to the ON position to make sure that they work and confirmed that they are pumping fuel.

I was reading a guys build thread and he said that the wrx injectors would lean out way too early and he ended up going back to stock 330cc's and they worked way better than his wrx 440's. Let me know how they work, im super curious, thought about buying some pnp 440's from Osidetiger off ebay but havent pulled the trigger yet, especially since i just bought some 550's for my gte ecu swap and then realizing they were just out of the range of what the gte ecu and compensate for...

He was also running a stock GE pump whereas i'm running a Denso TT 280 LPH pump.
I researched thoroughly before I purchased them (Especially on the my.is forum) and everything else that I found was positive, BUT I will let you know how it runs this evening after I get it running. Only problem is that I don't have a wideband yet, so I can't give you AFR numbers.

Also, I think you have a obd1 2jzge so the 02-05 wrx injectors will work for you, but i have a 2001 vvti 2jz and the lower runner's are different post 1997, so i dont think the 02-05 injectors will work for me. Maybe another year wrx injector is a direct swap, but im not sure.
