Hi all.

Im just wondering what would need to be done in order to put a rb30 bottom on my rb25de neo head. I have addressed a few points below.

The reason why i started this thread was due to; most of the other threads related to this topic were unfortunatly trolls or didnt have any information in relation to cost and power gains

I know that selling my car and getting a GTT is a better option

but im an NA fan. :D

Easy to do.

Approx cost.

Parts needed.

Raising compression if need be or the best way to raise them.

Approx power gain.

All advice would be greatly appreciated.

Cheers.

Unless you want to spend a small fortune dont bother. Getting power out of a n/a isnt cheap.

Theres a guy on the r31 forums who had a worked n/a rb26 and spent a crap load, over 25k i think. He only got 170-180 rwkw. Considering what else you can do with that sorta money makes it a pretty stupid excercise.

Not saying it would cost anywhere near that but that just gives you an idea, it'd cost over 5k to get a decent n/a motor imo.

If you have a 34 you really need a turbo, there to heavy for n/a. Only cars close 1 tonne are good n/a.

Cheers for the help guys.

These damn p plate laws are so annoying.

Although i do understand why they are in place.

looks like im stuck with a slow na r34 for another 3 years because you have to be 22 to get off your p plates now :(

FML.

Cheers.

you do realise that putting a rb30 bottom end into your r34 would also be illegal?

if you want something faster than your r34, get a late model commodore or falcon and put a shorter diff ratio in it. won't be quite as good on the highway as it would be with the stock ratio, but round town it will be much faster.

or a 3.5L v6 manual magna. they will do the 1/4 mile in under 15 seconds (my last one did it in 14.8 with just a catback)

Damnit beat me to it :P

I know a way it can be done! :whistling:

But, expensive beyond your worst nightmare would be the first reason you wouldnt do it.

The second is what zebra said. Very smart move!

Third... save your money and survive your P's with the small amount of points they give you. The if you want something faster, just go and buy it once your off your P's.

the natro ones will beat a natro skyline, but that is beside the point. the main point is that the dash looks like the cockpit of a 1950's plane that has been butchered to fit in a car.

My na r33 smashed my mates na supra.

Damn their interiors are so damn ugly lol

    • 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.
