Hi Guys, I know it is probably asked a bit but not easily found...

I was going to be putting an RB20det from my friend's car into my 180. This isn't going to happen in a hurry due to an issue with my mates replacement motor.

My question is this;

I have an R32 RB25DE lined up for $1000 (already have the box from it). Working within a close budget to what I was (1000-1500 to get it in after purchase of engine package) would I be better of going this way rather than looking for another RB20DET?

I know it is a good option if I spend some cash on the motor but I just really want it to be a step up from what it would have been with the RB20DET.

I have AN idea on what is required but it is an internet and hear-say understanding. I know that is all I will get here :nyaanyaa: but can anyone in the KNOW please confirm for me what I would need to do to get it up and going to a point that I could be safely and smoothly getting 180-200rwkw?

(GTST Injectors, GTST AFM, Manifold, R33/R34 Turbo, Turbo Lines, Dump Pipe, and ECU? - anything missing?)

I am not sure if a head gasket is required, what thickness and how much would I expect it to cost me to have fitted if required?

Another main question is would I run an RB20DET ECU? Does it plug straight in, and is it able to be tuned it to suit? (or is another ECU required)

Anything else anyone could help me with would be great so I can make my decision if to get the motor or not!

Any experence or results with this setup would be sweet!

Thanks guys!!

Todd

hey ask same question in na section its been cover lots and lots of times might get better answers, but here ya go

As for ecu yeh go the rb20det ecu should be fine and safe tune but to get 180-200 it would need to be rom chipped ie by dr drift or the likes, or get an safc, emanage or the likes,

You will also need a fuel pump, crossover pipe with bov and of course intercooler and piping, and front pipe. you shouldnt need an afm but mine blew when i did turbo conversion may have just been old cause no-one else who's done the conversion has had a problem.

Head gasket isnt required but with you will be limited with boost, on stock ecu i wouldnt go passed stock boost on a tuneable ecu it depends on the tunner but you should be safe enough to run 10psi, 12 max but i and most others wouldn't suggest over 10, boost will come on reallly early i think i get full boost at around 2000rpm on stock turbo

all the parts needed can be sourced as stock items and will run fine but to get 200 you would prob need some better than stock items ie front mount, exhaust, fuel pump ecu and mabye a fpr should get you there and it will be nice and torque esp compaired to an rb20.

Hope that helps your descision

cheers Jarrod

      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.
