(NA) SR20DE with aftermarket turbo? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I have a question for you, zilvia denizens...

There is a 240sx for sale near me that has a naturally aspirated SR20DE motor with an aftermarket turbo fitted to it.

Other than the turbo, are the parts generally interchangeable between SR20DET's and the NA SR20DE? I would guess that if they SR20DE required specifically different parts, they would be more expensive to procure.

Any insight on this idea?

what parts are you talking about??.. When it comes to water pump, oil pump, timing chain. yes. dizzy, cap and rotor will come from the nissan NX.

dont confuse it with the infinity G20 or the Sentra SE-R. the motor is the same (SR20DE) but cap and rotor are bigger than the RWD SRDE

Well, for instance, he has a GT35R turbo with custom header, downpipe and exhaust, but I am not sure if that is because the turbo did not come with those parts, or that a kit for an SR20DE does not exist. If I needed to replace any of these parts, having them custom made again could end up being more costly for me.

(I am not as well versed in these subjects as I'd like, so please, bear with me.)

Anything SR-DET fits DE when it comes to turbo manifold. You can slap an OEM manifold and a T25 and call it a day. As for the oil feed, they might've routed it how you would with KA-T's.

Understood! Thanks for your insight.

Remember DE are 9:1 vs 8.5:1

But othe than that, most parts interchange
