Rb25de neo to rb25det neo

[Whiteysr34]

Hello everyone so I have a question about the rb25 engine. So in my skyline r34 gtt I have the rb25de neo engine but I want to get it turbocharged. What parts will I need to get for it to work properly?

A GTT is a turbo.  Is it really a GT, or has someone put an NA engine into a GTT?  The reason for asking/caring, is that it will have some effect on our answers.

Ya it was a typo I just noticed. It is a gt

You wanna put in a DET or add a turbo to the DE?

Add a turbo to a de

[GTSBoy]

A turbo, a manifold to hang it off, a new dump pipe and front part of exhaust.

Turbo oil feed lines and suitable source for the oil + return to the sump.  Turbo water cooling lines, with again, suitable source point and return.

Turbo inlet pipework.  New AFM (assuming you're sticking with stock type ECU - otherwise, you might be deleting the AFM).  New airbox/filter arrangement to suit whatever you choose there.

Front mount intercooler, plus pipework from turbo to throttle.

Bigger injectors.  Bigger fuel pump.

Suitable ECU.  Going +turbo is best done with an aftermarket ECU.  The DE ECU expects to see a boost sensor that you don't have and won't want, except to satisfy the ECU's demand to see it.  The DE ECU is not as well set up for a turbo engine.  I actually do not know if the DE ECU can even be Nistuned. I would assume it can.  You need to be able to Nistune it if you want to use a Nissan ECU.

Brakes.

And, the howto.  This has been covered many many times.  There are threads on here that you can search up on how to add turbo to RB25.  Look 'em all up.
