Grunta, I'm not sure about the ECU on the GTT vs NA on the Auto models. From my understanding you still need to run engine management? Someone might want to clarfiy that.

How much are RB25DE's worth for resale? I'm just thinking what the cost for you would be to Buy half cut, deliver it, remove old engine, install new engine, then whatever else still needs to be done after that; vs keeping your engine, even still removing it and doing internal engine work. I'm not sure exact costs, but would that not be rather close to that of complete engine swap? A rebuilt GT-V I think would be better than simply swapping over for a DET, if you're looking at removing the engine.

havent you forgotten to list pistons ? you need low compression pistons, otherwise using the standard high compression pistons that NA's have will just F*&k ure engine VERY quickly.. although i h

i have a 1993 r32 gts with a rb20det conversion. i bought it this way so i dunno whats been done. power seems sweet up until 5000rpm, where it seems to hit some flat spots in power from there onwards.

hey i just though i would go back a little bit and add something in, in relation to drilling the oil return line into the block a way of getting around this would be to buy an oil cooler and run the o

Well I'm almost ready to have it all put in!

Just waiting on FMIC and catch can to arrive, then need to try get a factory BOV or cheap but good plumback and pod filter.

I also believe that I will need a silicon aftermarket or factory induction pipe that goes to the turbo inlet...or can the factory one be modified to suit?

Also any recommendations for tuning places? I think Robin said he usually sends them over to APC, something close to slacks creek would be ideal to get it all done together.

How driveable is an RB25DE+T without having the tuning and timing adjustments done straight away?

^ driving it straight away without any tuning or timing would be highly not recommended.

ecu will be running nuts with all the extra air & shiet coming thru..

will a stock manifold from a R32/33 fit on a R34 neo?

Yeah the figures can add up quite quickly, but it depends on where you get parts from. Keep a look out on ebay as well, I've seen some R34 Neo model turbos going recently, and even saw a set of neo injectors listed at $20 starting! Check the for sales here as well, always bargains keep coming up, and on NS.

I decided to see how I go with a Monsta Performance Delta Fin Intercooler. They sell on ebay for $350+$54, but lately they've done some starting at 1cent. I didn't have much luck the first time fighting over it in the last minute, but second time around I picked it up for $252 plus $54, for a full kit. For what it's worth I'll see how it goes.

I'll probably get it done at PerFourMance motorsport in Slacks Creek, pretty sure there's tuning places around there, it's like performance heaven down there lol Hopefully getting it from workshop to tuner won't be too much of a problem then.

Robin at Perfourmance said he usually sends them over to APC, which is about 1.9kms away. Then again, a brief search spat out some not so favourable results, so now I'm really not sure of where to go.

I'm still getting to know the places around Brisbane to get work done, so I'm really open to suggestions. I don't want to break the budget in labour, but I'd rather spend a little more if I need to and get quality work done..specially when it comes to the tuning of a RB25DE+t

I'm probably going to proceed with the conversion either before or after xmas. I want to take a trip back down to the Gong for xmas though, so that's why I'm thinking after xmas. Though I've got pretty much everything in or on the way except for a BOV and pod filter, so knowing me I'll get impatient and just get it done with :D

I've been thinking of options with exhaust as well, contemplated the idea of having a 3" mandrel bend (or 2.75"??) made up with resonators and a GTR Muffler if I can get hold of a cheap one. That way I can keep the factory look and stay quiet, and I figure that the GTR Muffler should flow well enough for my needs. I'm not sure what the weight would be like though compared to an aftermarket S/S.

^ thanks nate dawg.

other things im getting are brand new; fuel pump, intercooler,exhaust etc

No worries man

I picked up my Walbro GS342 on ebay for $145 posted from http://stores.ebay.com.au/PERFORMANCE-WORLD-STORE:

http://cgi.ebay.com.au/ws/eBayISAPI.dll?Vi...em=320308878704

They are super quick with postage. I bought it on a sunday, had it delivered to work, it was on my desk when I got there!

As for intercoolers, I got one of these Monsta Intercoolers on ebay http://stores.ebay.com.au/MonstARetailCentral.

For the price I'm willing to see how they go:

http://cgi.ebay.com.au/ws/eBayISAPI.dll?Vi...em=220294349334

They do one listing at a time starting at 1cent. Or you can choose the buy it nows, works out around $400ish posted. I got mine $304 all up in the end, it's a bit of a fight bidding for it in the last few minutes though.

Exhaust, unless you can pick up a second hand one, just get a custom one made up. Mr XTC might have a 3" catback for sale if he doesn't give in to doing the turbo conversion :/

      Rv37 400r questions

      By elir32 · Posted

      Hey guys. I have a 400R on its way to Australia from Japan currently and have a few questions I’m hoping others may be able to help with.   Wondering if anyone here has had any luck getting the Sat nav unit to work in Australia!? Assuming the Stereo is as simple as a band expanded and tv won’t work?  Seeing as they’re based off a Q50 which is Aus delivered is there any way to link that system to the nav? Nav modules and head unit are different part numbers and appear slightly different at the rear with plug ins etc. can I put my xtrail sd card into the rv37 and will that convert the maps or update to Australian? Has anyone got any advice here?     also has anyone fitted the factory remote start and Security system once it’s landed in Australia? I put an enquirey to Nissan Japan in via a third party, and they suggested it needs a Nissan Japan dealers device to setup and couldn’t guarantee if one here could do it or not. They can supply and I can physically fit it but to setup I would need a dealers device. Any information here would be appreciated also. I’ve seen one here with it fitted already prior to leaving Japan at a dealer/inporter, so clearly passes compliance and works when fitted Japan and doesn’t need changing here.      also, does the tyre inflation sensors work here? Does anything change with them when the vehicle arrives? Where are they actually situated? I’ve read they have batteries and they need to changing at times and seems like resetting involves the nav system?    any help here would be appreciated and any other aust specific information to help would be great. Looking forward to see what the current generation skyline is like and eager to see how many of the gadgets can be utilised here.  Thanks in advance

      Do need to take it with a pinch of salt. One of the adapter failures, they clearly had setup issues with the flywheel.  One of the slipping ones I spoke to and it was pretty clear the throwout was riding, rather than fix, just swapped to a new clutch.    These clutches are being put in anything from 5k offroad 4x4 beaters, GR yaris, 500hp commodores to 1200hp barra monsters. Bound to be some issues in some of them when they are not a simple bolt in affair due to the changes in height.    There is a lot going on in this picture and unless I did the job myself no way to tell what really happened.

      R34 GTT Battery Relocation To Trunk

      By NZ-GTT · Posted

      I did this mod in 2019  You just have to modify the top bracket of the ABS/TC/Fuel Pump Control ECU so it sits more upright and closer to the back seat and run a good quality positive battery lead from the engine bay, the negative lead i just bolted down to the body in the boot.
