Hey all, my mate has finnally got his R34 GT-T (very nice car to drive btw) and seeing as my car is going into the shop tomorrow for a NA-T conversion I was wondering what light mods can be made to this stock engine to at least keep our cars reletively on par (only going to run 5 psi on mine for at least a few months).

So would it be beneficial to swap out the stock ceramic turbo for a ball bearing one of equal or* greater size, and what can be done to give the RB25 the lowdown kick like the 2JZ (short of expensive stroker kits and twin turbo setups of course :)).

I don't really know a great deal about modifying Skyline engines so any help is appreciated :)

remember that because your converting from N/A to a turbo setup you can only run minimal boost.

as the compression from the NA motor will be way higher than the turbo equiv.

stick with the stock turbo and around 5psi or whatever the tuner is ok with.

you might find any more boost will kill the motor without compression change (ask the tuner).

    • 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 
    • 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.  
    • There's a good German place in Brisbane if youre up for the drive 😛
    • 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.  
    • 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.
