Gts-4 Motor Conversion

[stump_69]

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!!

R33 GTS4 engine swap to turbo

try using the search function next time.

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 ) . 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

Yeah I'd be a putting boost controller on anyway so I'd do it at the same time, so I'd just get a r33 25det computer and I'd be set?

Thanks for your help mate

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.

will be a stright swap mate, sump and all

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.
