Hey guys, I've got a r33 series 1 gts-4

And I'm looking to put a turbo motor i'n it, from what I've been told I'll need a stagea motor.

I Just wanted to know if I'll have to change my loom?

And if i buy a motor, loom and computer package from a stag

It would mean the computer would be suited for an auto?

Meaning i would need a manual computer from an r33?

I also was told the sump would be different, I'm Just trying to figure out what i need to do, any help is appreciated!!

RB25(4WD) stagea motor. Its just a turbo gts-4 engine so it will fit no problem

and also RB26 will fit in no problem but with more parts needing to be changed ... obviously

It will work fine with the loom you have now but not very tidy, they are different looms. You will spend more money keeping your old loom because you will need a boost controller or you will be stuck at about 6 psi. But if your looking for over 200kw + in the near future then your going to end up with a boost controller anyway so fit it while you have the easy chance.

You can use a r33 ECU being a manual because stagea manuals are pretty rare or even a 300zx ECU with board modifications and NISTUNE (good power :thumbsup: ) . It all depends on what you want to do.

The sump is not a problem. Its the same on a stagea as a GTS-4

In the end you could use the ECU you have now aswell. Just saying you can use any ECU but because they have different features E.G. a r32 GTS-T one would be fine but you wont be able to have VTC.

Best thing for you to do is look into a AFM tuneable ECU or even better a MAP-able ECU as they are a lot more fun.

what is a map able ecu, like a Power FC? also would you just suggest a r33 GTST loom and a power fc to match?

Yeah it just needs to be a ECU for series 1 or series 2 specific if hes leaving it stock or it will idle wrong and wont rev over 3000rpm. The wiring hardness's are also series 1 or 2 specific but not so important if the differences are turbo and NA (already stated those above).

A power FC is a ecu that can tune itself around sensors like the AFM etc etc, so if you want to change things like BOV,Injectors etc etc you can work around stalling isues and other things like idle and tune the car but because your using sensors to do it you have a limit to power and how well it really works. With a MAP readable ECU it reads manifold pressure basicly its a better way to calculate everything, way more power, way more accurate and dont need to use things like air flow meters.

    • Power is fed to the ECU when the ignition switch is switched to IGN, at terminal 58. That same wire also connects to the ECCS relay to provide both the coil power and the contact side. When the ECU sees power at 58 it switches 16 to earth, which pulls the ECCS relay on, which feeds main power into the ECU and also to a bunch of other things. None of this is directly involved in the fuel pump - it just has to happen first. The ECU will pull terminal 18 to earth when it wants the fuel pump to run. This allows the fuel pump relay to pull in, which switches power on into the rest of the fuel pump control equipment. The fuel pump control regulator is controlled from terminal 104 on the ECU and is switched high or low depending on whether the ECU thinks the pump needs to run high or low. (I don't know which way around that is, and it really doesn't matter right now). The fuel pump control reg is really just a resistor that controls how the power through the pump goes to earth. Either straight to earth, or via the resistor. This part doesn't matter much to us today. The power to the fuel pump relay comes from one of the switched wires from the IGN switch and fusebox that is not shown off to the left of this page. That power runs the fuel pump relay coil and a number of other engine peripherals. Those peripherals don't really matter. All that matters is that there should be power available at the relay when the key is in the right position. At least - I think it's switched. If it's not switched, then power will be there all the time. Either way, if you don't have power there when you need it (ie, key on) then it won't work. The input-output switching side of the relay gains its power from a line similar (but not the same as) the one that feeds the ECU. SO I presume that is switched. Again, if there is not power there when you need it, then you have to look upstream. And... the upshot of all that? There is no "ground" at the fuel pump relay. Where you say: and say that pin 1 Black/Pink is ground, that is not true. The ECU trigger is AF73, is black/pink, and is the "ground". When the ECU says it is. The Blue/White wire is the "constant" 12V to power the relay's coil. And when I say "constant", I mean it may well only be on when the key is on. As I said above. So, when the ECU says not to be running the pump (which is any time after about 3s of switching on, with no crank signal or engine speed yet), then you should see 12V at both 1 and 2. Because the 12V will be all the way up to the ECU terminal 18, waiting to be switched to ground. When the ECU switches the fuel pump on, then AF73 should go to ~0V, having been switched to ground and the voltage drop now occurring over the relay coil. 3 & 5 are easy. 5 is the other "constant" 12V, that may or may not be constant but will very much want to be there when the key is on. Same as above. 3 goes to the pump. There should never be 12V visible at 3 unless the relay is pulled in. As to where the immobiliser might have been spliced into all this.... It will either have to be on wire AF70 or AF71, whichever is most accessible near the alarm. Given that all those wires run from the engine bay fusebox or the ECU, via the driver's area to the rear of the car, it could really be either. AF70 will be the same colour from the appropriate fuse all the way to the pump. If it has been cut and is dangling, you should be able to see that  in that area somewhere. Same with AF71.   You really should be able to force the pump to run. Just jump 12V onto AF72 and it should go. That will prove that the pump itself is willing to go along with you when you sort out the upstream. You really should be able to force the fuel pump relay on. Just short AF73 to earth when the key is on. If the pump runs, then the relay is fine, and all the power up to both inputs on the relay is fine. If it doesn't run (and given that you checked the relay itself actually works) then one or both of AF70 and AF71 are not bringing power to the game.
    • @PranK can you elaborate further on the Colorlock Dye? The website has a lot of options. I'm sure you've done all the research. I have old genuine leather seats that I have bought various refurbing creams and such, but never a dye. Any info on how long it lasts? Does it wash out? Is it a hassle? What product do I actually need? Am I just buying this kit and following the steps the page advises or something else? https://www.colourlockaustralia.com.au/colourlock-leather-repair-kit-dye.html
    • These going to fit over the big brakes? I'd be reeeeeeeeaaaall hesitant to believe so.
    • The leather work properly stunned me. Again, I am thankful that the leather was in such good condition. I'm not sure what the indent is at the top of the passenger seat. Like somebody was sitting in it with a golf ball between their shoulders. The wheels are more grey than silver now and missing a lot of gloss.  Here's one with nice silver wheels.
    • It's amazing how well the works on the leather seats. Looks mint. Looking forward to see how you go with the wheels. They do suit the car! Gutter rash is easy to fix, but I'm curious about getting the colour done.
