Hey guys, I own a '93 R33 GTS-T Skyline and have decided that this year I'm actually going to do something to it instead of just talk about it, haha... But what I want to do, I've only heard that it's possible... And I'm not 100% if it would... So if you guys know if it's possible and what I would need to do to make it work, feel free to throw in your knowledge please.

So here we go...

40' thou oversized pistons, H beam rods, RB26DETT crankshaft... That's the basics at the moment... Turbo is still unchosen and headwork will be done to what is needed. I've heard that this combination will stroke the RB25 to an RB26 or an RB27, but I doubt it personally.

I'm not after massive horsepower, I want a decent street car I can thrash at the track and come home afterwards. Like I said, feel free to throw your opinions at me. More help I get, the more knowledge I attain, the better I can make the car.

I will eventually be going down the RB25/RB26 stroke path later this year. This subject has been covered a little bit on the forums, please use the search function. You will also need to use RB26 Pistons along with the RB26 crank due to the extra stroke.

Any particular reason you want to go straight to 40' pistons? I would suggest going for 20' so if you ever have to rebuild, there is still enough material to remove from the bores, and pistons are readily available.

Using oversized pistons is not stroking a motor.

But bit of a thread dig there Abe :)

    • That still isn't a lot to go on. I don't have a Y50 Fuga Head Unit wiring diagram. I can say that a lot of nissans of that age shared head unit plugs, so if you are in Australia something like this would probably help: https://aerpro.com/app091# You plug that into the car loom, then either plug the head unit ISO into that (if it has ISO), or you buy and ISO adapter harness that you wire in. Bit of stuffing around, but once you have ISO its easy to change things in future.
    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
