The Nissan SR20DET is a popular 4-cylinder JDM engine known for being the heart of the Nissan 180SX and Silvia. SR20DET engine swaps are popular in North America for 240SX owners.

Nissan SR20DET engine code:

SR - Engine Family
20 - 2.0 Liters Displacement
D - Dual Overhead Cam
E - Electronic Fuel Injection
T - Turbocharged

Nissan also produced a cheaper naturally aspirated (non-turbo) version of the SR engine called the SR20DE. The SR20DET engine replaced the CA18DET that originally powered the Silvia and 180SX. Different variants of the SR20DET engine have different color valve covers.

Red Top SR20DET (1989-1994) S13 Silvia, 180SX, Pulsar, Bluebird
Black Top SR20DET (1994-1998) S13 Silvia, 180SX
Black Top SR20DET (1994-2002) S14 Silvia, S15 Silvia
Silver Top SR20DET (1995-2001) Avenir

The SR20DET engine was first used in 1989 in the U12 Nissan Bluebird 2000SSS Attesa. From 1990 to 1994 the SR20DET was used in the Nissan Pulsar GTi-R (N14) but with a larger Garret T28 turbocharger. In both cars the engine is mounted in an East/West fashion but in the Silvia and 180SX the SR engine is mounted North/South.

Then the SR20DET engine was used in the Nissan Avenir in 1995, the Nissan R’nessa in 1997, and the Nissan Liberty in 1999. The S14 and S15 Silvia use a larger Garrett T28 turbocharger. The S15 Nissan Silvia Spec R trim level SR20DET uses a T28 Garret turbocharger with a dual ball-bearing center cartridge compared to the ceramic center cartridge present in the S14 Silvia. The Nissan Silvia was the longest running model to use the SR20DET engine.

can the sr20det engine fit in the mitsubishi galant sigma 2?

I couldn’t find any evidence of someone performing this engine swap, but seems to me there would be enough room in the engine bay for the SR20. Probably have to fabricate or weld engine mounts.

sure can fit a sr20det into a mitsubishi sigma but i’d go with a 4g36t out of a mitsu galant. 4wd stronger motor in my opinion.

HEY DUDE WOULD THE SR20DET BLUEBIRD FIT IN THE 07 NISSAN ALTIMA 2.5?? WOULD IT FIT TO DO THE ENGINE SWAP??

Tom, on August 5th, 2008 at 12:00 am Said:

I think SR20 would fit, but it’s going to take some fabrication to get that rear wheel drive transmission in there. I would buy a 240SX with the SR20 engine swap instead of destroying a new car. Cost would be comparable.

I’m going to put a turbo in my 240sx on its stock KA24DE. How many psi of boost should i use??

dan, on August 29th, 2008 at 6:35 pm Said:

what would be a good engine swap for a 97 200sx thats not too expensive?

Nick, on September 1st, 2008 at 9:20 pm Said:

Hey would a SR20DET fit into a s14 silvia without changing the engine mounts? if the engine originally was out of another car?
