Why are you replacing the turbo at 100,000km (if that's genuine km)? If you want a bigger turbo you have to also look at intercooler, exhaust, injectors, fuel pump etc and of course an aftermarket ECU or a Nistune chip. The only coils I would suggest are OEM or Splitfires - and of course plugs while you are there.

The crank sensor is unlikely to need replacement nor is the sensor on the air intake (MAF sensor) but by all means replace the O2 sensor on the exhaust downpipe.

There is heaps of information in the Stagea (wagoneers) section especially in the DIY section.

Well if you are after a stock replacement it depends where you are - good idea to put your city and country at least in your profile. Most popular replacement that you can run with stock ecu etc is one from Hypergear (look up his thread and give him a phone).

Check the turbo for shaft play first. If that is OK, just fix the leak. If you want to go replacing the turbo, you'll be finding you need to do quite a few other things as well to make it worth it: exhaust, valve body upgrade if an auto car, FMIC, and tuning.

If you need to swap turbos without the supporting modifications, Id ask about turbos smaller than the 21U hypergear high flow unit. That will keep the engine response and power curve close to stock - something that is an important consideration for a daily driven, heavy vehicle.

Well I know hks do a 2.8l strocker its got the plate from khs under the hood saying it's a 2.8 with the engine builders name with 2.8l badges all over it probably got taken out before it come over and yeh I'm 99% certain its stock turbo seams like stock ecu a well so that points out it's not

Turbo is definitely leaking and has heeps of play in it I'm not going back to stock here is what I'm looking at 

6boost manifold twinscroll 

GTX 3076R GEN 2 (not sure what housings to get or if x2 waste gates is necessary )

225 walbro fuel pump 

550cc injectors 

Spitfire coils 

Trans cooker

Looking at haltech ecu or nistune 

forward facing plenum 

Pwr radiator 

Its automatic and its staying that way so I know I need to keep the power around 280kw and even then I'll probably kill it so what auto trans options do I have other then a rebuilding the current 1 any 1 put a 5 speed or 6 speed auto out of something elce onto a rb25?

    • I've unfortunately never been as they're on the complete other side of the continent and another country that isn't currently letting us in as easily as they use to. I even heard their stop signs over there actually say "Stop" instead of "Arret". If I decided to trek the 48h drive, I wouldn't know when or where to stop haha. Whenever I order parts from UP Garage, I order from Japan as it's cheaper. Same with GKTech... oddly enough, it's cheaper shipped from Australia then it is the US.  UP Garage Japan operates their US leg though, unlike Tomei. If Tomei JPN had the power to close down Tomei USA, I'm sure it would be done in a day. They're two completely separate entities. Tomei JPN messed up somewhere originally agreeing to its creation and got sacked big time. 
    • I asked someone about this and he told me about the Audi 1.8T engine. But I think it would be difficult to swap
    • I don't know that machine specifically, but I'd personally go for something with a little more kick than 130amp. Around up to 180 would be good. At the 6mm range, you're really pushing the machine hard and don't have a long period you can run for with out needing to give it a rest. Lots of MIG machines come with a regulator and hose. A lot will come with a starter roll of wire too, but it isn't too expensive to buy. I'd recommend NOT buying a massive roll too, as you don't want it sitting around FOREVER in the machine between uses and potentially going to shit. For thin sheet metal, get a roll of 0.6mm if you're doing over 3mm and above, switch over to 0.8mm wire. Even by 2mm you'd probably really want to switch. As for gas battle, it's all swap and go style now. You'll pay a bottle deposit, and then X amount to swap for a full one. I think it's like $200 or $300 for a D Size bottle upfront as "deposit", and like $110 to $150 per swap. My D size CO2/argon bottle lasts a fair bit of welding on the MIG. And I run an E size bottle on the TIG. For DIY MIG, stick with a D size bottle. If you really start to get into a LOT of welding and doing it really regularly, then upgrade. If you're like most DIY car guys, one D bottle will last you 2 or 3 years easily. I think I've been on my current bottle about 5 years. It is starting to get low, but I've been smashing it a lot more the last 6 months.
    • SR20s came with cars like the Bluebird and Primera, but the RB20 never came. The ones in Turkey were either brought in specially or from abroad. That's why RBs aren't as common as SRs. And if a part breaks or I need to replace it when doing maintenance, it's harder to find parts for RBs.
    • I would suggest equally difficult to find, perhaps edging to the SR. Turkey has almost exclusively Euro market cars, some Korean, few Japanese other than pedestrian shite. I guess they're probably losing the fight against Chinese shit like we are now too. I would vote for a BMW V8, found in a 540i in a wrecking yard somewhere in Deutschland (or possibly Albania).
