They are the same with the exception of ECU, MAF, coil packs and external vs internal ignitor. The nitty gritty is all the same

Coil packs and water pump pulley look like S1. CAS looks like a S2 though.

Tps looks to be the type on s1

Tps does look like S1 from those pics. Take the accordion tube off the front of the turbo and take a pic of the compressor wheel. If the blades are single bladed then its a S2, if the blades are twin blade, then it's a S1 turbo. But from everything I've seen, looks to be a S1.

Thanks guys im at home now i have the car and parts at my parents house ill stop by tomorrow after work and pull the accordion tube off of the turbo and check and ill let you guys know what i find

that broken blue/purple plug is fast idle switch btw

that broken blue/purple plug is fast idle switch btw

Is this what causes the car to stall out when the rpms drop after going full throttle?
dreizm728
10-07-2013, 08:32 PM
Oh and is this also a distinctive switch determining whether its an s1 or s2?
ch1873857
10-07-2013, 08:41 PM
no s1 and s2 have the same aac valve. that is not what causes your stalling issue. a non recirculated stock or shitty bov will cause that.

i never use the fast idle because i dont run ac. it just kicks it up to 1000-1100 when the ac is kicked on. thats all.

non needed.

Everyone above saying S1 is correct. The CAS, the coils, the TPS and per your post the turbo are all S1. If you are looking for a ECU and are comfortable soldering some Z32 ecus will work if you rewire them and have them tuned. As for ignitor Z32s or any VG30DE will also work if you can find them.

Thanks its always good to know if i ever have a problem with mine I have the ignitor and an apexi pfc i currently have another rb in my s13 its an s1 thats the reason for looking for another s1 but due to my stupidness i locked it up by putting the wrong filter on so i pretty much have everything for it i worked for infiniti so i had a few foc filters laying around so i used it cause i didnt wanna spend $10 on a 55Y00 filter
