Hi ive stuffed my engine and gettingi it rebuilt. Am using metal head gasket , forged pistons, 660 injectors, fuel reg bigger turbo that starts making 0 psi at about 3 and full boost by about 4000 rpm. I am also getting new valve springs, cam gears etc. I am also planning on using a stallie for my car that locks at about 2800rpm. and was wondering could i get a lower rpm stallie and better set of cams to give me a bit more mid range torque? if so what type? I have looked at the tomei but they dont seem to suit my needs any ideas thanks ?

by the way im aiming at about 280-300 kilowatts at the wheels. this turbo can get that at around 18 psi

What turbo?

Honestly, stock cams are the best for your setup if you want response and mid-low end etc.

you'll get far more gain spending the cams money on beefing up the auto/shift speeds and so on.

Its a hypergear atr43g3 turbo and i am thinking of getting a stage 2 shift kit for it as well. Thanks for the input after looking on the net and around i think stock cams may be the best idea.

just by reading the forums regularly, people steer clear of using aftermarket cams for the rb25det, the cost benefit ratio isn't good enough, stock cams are seem perfect for a street car/occasional track, people have easily got upward of 300rwkws on stock cams.

unless you want you car lumpy at idle with less low down torq :S

And good luck getting 300kw through a stock auto with just a hi stall (sounds more like a more-stall to me though). If you are seriously aiming for that sort of power (which I doubt it will make through an auto) you'll need a built box! Look into KEAS gear - or even MV autos in SA.

Lumpy idle and low down torque lover signing in (260's :) )

IF you are deadset on getting cams, I wouldn't want to go further than drop in 256's.

not through an auto it wont, and even with a manual box you will be needing a fair whack more than 18psi

Obviously this is depending on dyno and conditions, but keep in mind that assuming what I have is actually a g3 and not a g2 (performs like a g3 but I swear I ordered g2, not like it matters...), then he should see 300rwkw with 20psi max. On ESP's dyno I made 294.4rwkw on 15.9psi so 18psi same conditions would easily net me 300rwkw on their dyno.

I wouldn't be surprised if it's a happy reading dyno, but I'm fairly sure that it reads almost the same as Autotech as well as Ultimate Tunes.

Obviously this is different given he wants to make it through an auto. Might as well go with a 3076r or 3082r

Looking into hyper gear threads this power is achievable with the turbo that i have mentioned at that boost. Also i did mention using a built auto ( shift kit ) etc with the stall etc. so anyone commenting please read the whole thread :)

We did read your thread - a shift kit and a stall is not a built auto. Its an auto with a shift kit and a stall. Good luck making 300rwkw with your stock auto.

    • 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.
