what about a full Cometic multi layered steel gasket set.

Full set for intake, exhaust, head etc. Cometic Street Pro - http://cgi.ebay.com/ebaymotors/Cometic-Street-Pro-Top-End-Gasket-Kit-R33-RB25-RB25DET-_W0QQcmdZViewItemQQhashZitem3efbaa0556QQitemZ270510196054QQptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccessories

no issues then running 18psi, right in the turbo nice-zone :)

same injectors, similar mods, gt3076r IW, chip+piggyback, 250kw@wheels (auto awd)

really an 040 isnt big enough???

mines flowing enough to feed 550cc injectors without a fuel reg or rail pressure bump and Im sure Ive read it can supply larger injectors too.

A fuel pump flows more fuel at a lower fuel pressure. Increasing the fuel pressure above standard will only make the fuel pump run out of flow quicker.

I would put a factory airbox on it with a panel filter.

So you already have the 4bolt dump pipe? That is handy!

Injectors: From my car I can extrapolate that if you want to run 11.5:1 on standard pressure then you'll only get ~250rwkw. If you bump up the pressure a tad and are willing to run to 90% duty then you'll get a bit more, perhaps 280rwkw. So they are borderline, but SHOULD be just enough. They are 450cc btw and allow a lovely idle.

Tune at 1.1bar and be happy - get a hand controller to self adjust the part throttle.

Then buy tyres in bulk.

I disagree with the factory airbox, you will loose a signifant amount of power. Its criminal on a 3076 imo. If you are certain on keeping the factory airbox then at least upgrade the intake piping to 3" metal. Someone on here had one made up and it was quite expensive as it must join the airbox at exactly the right location.

You will gain power with a 3" metal intake and pod (preferably shielded) when above 250rwkw.

See the quoted post above regarding those small injectors. It is criminal using such small injectors on a 3076 turbo, it will limit you. Otherwise, get a smaller turbo. No point having a large turbo running low boost and relatively low power.

Sell your current injectors and upgrade to larger ones, shouldnt be more than a few hundred changeover and then you will never have to worry about it again. You can then allow your turbo to do its thing, even run E85, or up the boost if you do an engine build one day etc etc. Not to mention it is safer to run injectors less than 80% duty cycle. Sell you fuel pressure regulator and put it towards the injector upgrade instead.

I would have to recommend getting at least 600cc injectors if you want to run pump fuel

and larger again if you wish to run E85 as others above have said and you shouldn't have

any trouble with larger injectors with a good tuner. have a look at deatchwerks in america

for larger injectors especially with the current exchange rate.

Whats your radiator like? A Gtst running 300kw makes a bit of heat esp. on a hot day. I'd get it serviced and cleaned [or new whatever you decide]. I'd even consider an oil cooler kit as well.

And you will want a boost controller, a dual solenoid one is the ducks guts.

But your setup is the basis for a lot of fun............

^^^ not essential at the very minute but top recommendation in future.

I would replace your 'cooler core mate, dont worry about the plenum. Browse the ForSale stuff for a Jap-brand second-hand one.

+1 for PFC hand controller!

      This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.

      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.

      Jacks that fit under GTR lips that can reach the subframe?

      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.
