Id like a fast street car but a daily aswell looking for 400hp maybe abit more but want to stay on pump fuel Will the gt3582r turbo be a good choice cheers for any professional info.

I put a 3582R on my RB30 Stagea but used .63 rear for max take off (heavy wagon) but would have preferred a .82 for a little more grunt on the track. Today I would use a modern turbo. Unusually a Wellington workshop did a back to back comparison on the same car (Skyline with RB30) and got the following results:

.63 rear at 18 psi = 350kw

.82 rear at 18 psi 375kw

I would suggest the .82 for you as it would be easy to get 400kw out of it and for a street car would drive better than with a 1.00 rear.

PS just noticed you only want 400hp not kw. You will do that with a GT3076 easily.

Thanks for the reply and your comments. What rev range will the gt3582r start spooling

This is with the .63 rear on my car -with VCT, Link ECU, mac valve, 50mm Synapse wastegate, Sinco manifold :

i have a borg warner s300sx with a .91 twin scroll housing on my rb25/30, and am getting a bar at 3700ish rpm, it makes 500hp on 14psi on pump gas.
 
and cost less than 1k NZD landed

What website was that

a 8375 s360

Did the physical bulk of this unit cause much packaging/fitment issues?

What manifold?  Pics would probably tell a lot for people contemplating the same unit.

Nah it's not too bad, I am running a sinco twin scroll manifold for a rb30, they make the collector lower for the 30.

A walk around of my setup.

 

i tried to add a pic, but for some reason its not loading :/

    • 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.
    • 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.
