Mate of mine dropped a R32 RB20DET in a Z31 with little dramas, so i'd be putting in a R33 RB25DET or if you have the funds RB26DETT.

erm their still turbocharged, i need an n/a engine, have you not heard about the ban on turbocharged cars for P platers? ;)

well if ppl say a rb20det can fit into a z31. then i highly doubt there will be much trouble putting a rb30 in (i'm sure someon on the 300zx forums has done it, and if not just measure it all up and that will give u a fair idea, u'll probally need custom engine mounts, but thats no big deal. better still while the rb30 N/A is in, save ur cash for a rb25 head and all the works to make a rb30Det for when ur off ur p's. beats any rb26dett!! :boobies2: :D

btw if u posted this up in the general tech section u'll prob get more replies....

Nissan 200ZR was Z31 chassis with RB20DET engine:

Most RB engines available have the sump bowl in the wrong place to drop into a Z31 chassis - the sump bowl is at the front in RB engines used in Skylines, but Z31 needs a rear bowl. Changing the sump is an option, but finding a rear bowl RB sump is not that easy.

Since you want an NA RB30, your best bet would be to get one from an MQ Patrol (I think that's right). These have a sump with the bowl at the rear, but its fairly deep so probably need some mods to fit. These are a carburetted engine (RB30S), but it would be a simple matter to bolt on the EFI gear from a skyline engine (R31). Bonnet clearance might be an issue as the RB30 is a fairly tall engine compared with an RB20 - fitting a twin cam head to an RB30 block actually lowers the overal height a small amount.

Yes you can fit an rb30 into a z31 things you will need are ( 200zr X-member, series 1 rx7 engine mounts and a modified front sump which will need to be made to clear the power steering lines and will need to get new power steering lines made due to power steering pump is on the other side of the motor will need to make radiator mounts due to the rb30 the original radiator won't fit also will need to run electric thermo fans too and also will need to make up a new radiator top line to have the filler neck high due to on the vg30et the filler neck is on the radiator and also on the rb30s it's on the radiator for the gearbox will need to make a gearbox mount and get a custom 1 piece tail shaft made too ) there is more like wiring but that's the easy part that's what I have done to make an rb30 fit into a z31

    • 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.
