stock injectors are usually good for about 150 - 160 rwkw i think.

The SAFC should be ok, it depends on how much power you want in the long run? a Power FC would be ideal.

Im not to sure about the GTR injectors.

RB25 turbo is a little bigger than a RB20. It makes more/the same power at lower boost.

Hope this helps, also try doing a search, this stuff gets covered all the time.

I think if you crank them up to 100% duty cycle standard injectors can be good for up to 180rwkw, ive had people tell me they are making over 200rwkw with the stockies but i don't really beleive that.

RB20 det uses top feed high impedance injectors whereas RB26 uses top feed low impedance injectors, so i think you can use them with a resistor pack or something.

rb25 turbo is substantially bigger than rb20 but if i were you id save my money and buy a brand new turbo. I mean ppl sell used rb25's for like $400+ and for around $1400 you can by a brand new, much better turbo, do it once do it right.

but yea, this gets asked all the time and has probably been answered in much better detail in another post so using the search button might be more helpful

the injector clips are also different between rb20 and rb26. had to buy bosch ones and put them in. also you may not be able to drive with just changing the injectors cause it will be putting alot more fuel into the motor. I had to have a heap of fuel taken out when I had mine installed.

ive personally seen stok injectors and pump do 185 at treads..

my mate has 210 treads stok injectors,remap and pump (other crap 2)

safc will be enough for injectors upto 440..any bigger need other fuel pc

the rb25 turbo is a gret upgrade,,but id buy it new..can handle more boost on the rb20 engine and makes the power much lower

rb26 injectors do need the clip change and resistor packs

RB25 turbo is alright to add as thats what i had last on my RB20det and got just over 180rwkw (If dyno was correct)

Its a good cheap mod to do as it will change the way the car feels with more top end and a little less spinning at bottom end as boost cuts in a little later

I heard a better mod is to add the ball bearing turbo from a S15 200sx but dont know anyone who has done that..

    • Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.
    • My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though. 
    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
    • BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
