i thought you bought the focus and that you would never buy any car thats older then like 5 years old?

anyways back to the subject. the difference between the S13-S14 and S15 SR20DET is the hp and other random stuff

S13 red/black top= 205hp 205? tq. it has a T25 turbo good for a maximum of 250whp with all the supporting mods. it comes with 370cc injectors that maxs out around the same hp as the turbo does. has a high port head so it flows better then the newer SR's.

S14 blacktop SR20DET = 220hp 205tq. this one has a larger T28 turbo good for around 280-290whp. the engine is a different design, it has a different intake manifold, a low port head that doesn't flow as good, however it makes up for it by having variable cam timing which really helps downlow before the turbo kicks in. it still runs on the 370cc injectors.

S15 SR20DEt = 250hp 205tq. a real S15 with a S15 SR run's high 13's stock. it also comes with the larger T28 turbo but i think the wheel is made of a different material so it will spool even faster, it has 480cc injectors which are good for just alittle over 300whp. other then that, its basically the same engine as the S14 SR. it also comes with a 6 speed tranny.

they all fit the same but its easier to these engines into a 91+ body style 240. but even the 89-90 models are not hard since its practically a direct bolt in. only the accesories and certain lines don't bolt up quit right.

any of these cars can be made to go pretty fast. its really how much you want to spend. with a sentra or 200SX it has more of a sleeperness to them.
