S13/S14/S15 SR20DET

Looking for an easy upgrade path for your S13, S14 or S15 SR20DET Nissan Silvia? Look no further than NZEFI.

Stage 1 210-225rwkW (approx. 280-300rwhp)

Full 3#8243; exhaust system from dump pipe back

S2 R33 RB25DET air flow meter (optional)

Apexi Power Intake air filter (bolts directly to AFM without an adaptor)

MGP front mounted intercooler kit

Walbro 255L/hr fuel pump

Upgrade to S14/S15 T28 turbocharger (S13 only)

Upgrade to 440cc/min or larger fuel injectors (S13 S14 only)

NGK Spark Plugs #8211; custom gapped

HKS EVC-S electronic boost controller

Retune factory SR20 ECU to suit modifications

Stage 1 represents a substantial upgrade over stock and makes the most power that is possible reliably with the factory  S14/S15 turbocharger.

Stage 1+ 210-225rwkW (approx. 280-300rwhp)

Full 3#8243; exhaust system from dump pipe back

KN 3#8243; pod air filter with AFM delete pipe

MGP front mounted intercooler

Walbro 255L/hr fuel pump

Upgrade to S14/S15 T28 turbocharger (S13 only)

Upgrade to 440cc/min or larger fuel injectors (S13 S14 only)

NGK Spark Plugs #8211; custom gapped

Link G4 plug-in ECU

IAT sensor for Link G4

XS Loom for Link G4

Electronic boost control solenoid for Link G4

In-cabin boost control knob or hi/low boost switch for Link G4

Retune Link G4 plug-in ECU to suit modifications

Stage 1+ does not make any more power than Stage 1 as the power is limited by the factory turbocharger. However, Stage 1+ will suit customers who are planning on chasing much larger power figures in the future. The fitment of a Link G4 during the early stages of modification makes future retunes easier and less expensive.

Stage 2 270rwkW (approx. 360rwhp)

Stage 2 uses all the same parts as Stage 1 but adds the following:

Genuine Nissan Z32 300ZX AFM

550cc/min side feed fuel injectors

60mm throttle body (required for S14/15 only)

HKS SQV3 BOV (plumb back recommended for best drivability)

Garrett GT2871R turbocharger

Retune factory SR20 ECU to suit modifications

Nissan Silvia

Stage 2 retains a near stock appearance in the engine bay while releasing substantially more power from an internally stock engine.  Turbocharger lag is increased slightly over Stage 1, but with all the new found midrange and top end lag wont be an issue.

Stage 2+ 270rwkW (approx. 360rwhp)

Stage 2+ uses all the same parts as Stage 1+ but adds the following:

550cc/min side feed fuel injectors

60mm throttle body (required for S14/15 only)

HKS SQV3 BOV

Garrett GT2871R turbocharger

Retune Link G4 plug-in ECU to suit modifications

Stage 2+ retains a near stock appearance in the engine bay while releasing substantially more power from an internally stock engine.  Turbocharger lag is increased slightly over Stage 1+, but with all the new found midrange and top end lag wont be an issue.

Stage 3+ 300rwkW (approx. 400rwhp)

While the stock engine internals can handle Stage 3+, it is important to have a tight engine in good condition before upgrading to this level. If your engine isn#8217;t in top condition to start with then we advise that it is rebuilt before attempting Stage 3+. If there is a possibility of moving to stage 4 later then upgraded engine components should be used in the rebuild.

Please contact us to discuss this in more detail.

Stage 3+ builds on Stage 2+ but gets even more serious with the following components:

SSI exhaust manifold with external wastegate modifications by NZEFI

Tial 44mm wastegate

Greddy plenum

Tomei fuel pressure regulator

Retune Link G4 plug-in ECU to suit modifications

At this level, you#8217;ll be glad you invested in a Link G4 as this has many features that are lacking on the stock ECU.  We consider Stage 3 to be the upper limit when using 98 Octane pump fuel and stock engine internals.

Stage 4+ 370rwkW (500rwhp) or more

The GT2871R will need to be upgraded at this point and don#8217;t even consider trying to make this kind of power on a stock engine.  Please contact us for more details so we can discuss your individual goals and requirements.  We have customer#8217;s with SR20DETs making over 800hp at the wheels so rest assured, we know exactly what it takes to make big power figures from these engines.
