Okay so im deciding what turbos to upgrade to and want to know everyones opinion.

Im wanting twin high mounts and want to get around 500kw or more..my motor is fully built and just needs a few extra goodies.

Im running greddy t517zs atm and its got over 300kw on low boost.

Im looking at getting a set of greddy t67-25gs as ive heard really good things but want everyones input so please feel free to voice your opinion guys.

Thanks

On petrol, or E85? What is "fully built"? Please elaborate on specs, and the rest of the setup etc? External gates? GTX2867Rs are the first thing that come to mind on the assumption you will be running E85.

^ As above..

Also need to understand what your car is used for and what you expect out of it in regards to drivability. As much as I love twins, for big power like 500kw I would lean towards a big single like a PTE6466 or EFR9180.

Whatever you do, stay away from the T67. That thing would be nearly 20-30 years old by now (technology wise)

Sorry guys.. Motor has forged pistons, rods, big injectors, fuel rail, n1oil pump, nismo oil cooler, nismo intercooler.. Its on pump fuel ATM and plan to get cams, cam gears, e85 and a few other goodies.. I want 450-500kw and was thinking td06-20gs for it as i think running twin t67s will be too laggy as is purely for street use. If i run the td06-20gs.. I'm not sure as to run 8cm or 10cm??

Thanks

^ TBH, stay away from the Greddy / Trust turbos. They are laggy by todays standards.

Get yourself a pair of GTX2867R like Lithium suggested or a big single like a PTE6266, EFR8374, PTE6466 or even a EFR9180 (all in in twin scroll configuration for response)

swings and roundabouts...

1. do you really want 500awkw? if so (unless it's going to be a hard parker with a dyno sheet in the windscreen)

2. start saving for a new gearbox

3. cash in the rego, throw in a seat, cage and buy a trailer (because unless your looking to get more cubes, it'll be essentially useless on the street)

4. start saving for all the supporting systems (I'll guarantee your fuel system wont support 500rwkw, clutch, cooler, oil and breathing mods, diff/susp/brakes, ign system, ecu/tune.... )

and the list goes on into a big spiraling dark hole of time/money and sacrifice/compromise

Cheers

You should get close with GTX28's shoved into -5 housings, twin Walbro 460L, possibly 1400cc ethanol/methanol injectors (or just put 2000's in there)

The rest can be done on a surprisingly stock engine bay, but be warned, the 26 block is very weak up around that power. I would be going for an unmolested 3L block and not boring it out much.

Nah, 26 block is no stronger or weaker than a 30 block, do what everyone does and do a partial grout fill for ridgitidy.

If anything the 26 block has oil squirters and the block grove for extra mains oiling already there, i wouldnt jump to a 30 block just for 500Kw.

Good Oil pump is a must in any RB build as is oil control mods.

You can get 400-450Kw with a set of low mount -5 and E85....

Appreciate all your input guys..

I'm totally new to all this so i do appreciate all your feedback guys

To start with, be honest with yourself and really have a good think about what you want to get out of your gtr and how you would like to use it. Once you figure that out, you can start setting goals and planning mods/asking for advice for the best way to get the result your looking for.

Cheers

      Does RB25DE Neo lower intake work with RB25DET Neo Upper intake manifold?

      By R34_GT to Turbo · Posted

      Ok I get you. But isn’t the butterfly intake a headache with the +T?  see this is my plan so far but please advise me into the right direction.  Nistune Ecu, 1000cc Bosch injectors, TD05 or TD06 Kinugawa turbo using stock rb25det exhuast manifold, walbro fuel pump unsure of model I think it’s 450/460, spitfire coils and sparks to suit and a R35 MAF sensor and boost sensor.    I was thinking maybe do a cheap eBay plenum $400-500 or try find a stock det neo intake. I think I’d port match it so it’s getting the full capacity but open to advice please.  Thanks

      R32 GTS (RB20DE) Injectors Replacement

      The issue now is the 'fuel cut' while driving, and when it happend, it does not stall. This, I did not test the fuel pressure while driving as I cannot with a fuel pressure gauge. I do have Nistune logs, yes. I have also replaced the MAF Sensor.   Also related to the FPG Fuel Hanger – I just realized that I need a Deutsch Crimp Tool to crimp some cables for the FPG Fuel Hanger. Need to purchase additional cables as the kit only included 2, which are for the float. FPG has not responded to my emails so far since purchasing. I thought about taking it to someone and having it done professionally, but I am reluctant since everyone I took it to messed up in some way.

      The German place in Cabramatta was rock solid, fresh pretzel cooked to order back then. Then it went all quiet, after all the poker machines were removed, then I believe it closed for good. I did drive past the other week and noticed outdoor lighting a big screen, but no idea what is there now.

      R33 GTR running -9 with no tune

      By joshuaho96 · Posted

      Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.
