i already ordered a $300 used rear diff for r32, so i guess this is cheaper. i just want to know that incase the used one breaks too, should i upgrade it to a cusco 1.5way one? is it any good? for o2 sensors, can i buy 2 widebands and put them in? can they connect to factory ecu or do i have to get a aem power fc or some sort? thanks!

both battery and alternator is new, the mechanic checked my car said injectors are fine so didn't sonic clean them im installing the hicas lock bar either way, just want to know what do i do with the original plugs and hydraulic line. the diff oil was changed recently and its still making noise thanks

thanks for answering! for o2 sensors, i see 2 around turbos and i know theres one more around catback, which one should i replace or should i replace all of them? for hicas, i am installing the lock bar, but I'm not sure what should i do with those hydraulic lines, and can the whole system be removed completely? for rear diff, I'm hearing "thump, thump, thump, thump" noise while driving around 10-30km/h, any speed after 40km/h it turns into a whining noise. turning doesn't change the noise. while turning rear wheels by hand, i can hear something like metal grinding noise. a mechanic told me to shim it but i thought its not gonna last long so i ordered a used one. the cusco 1.5way cost around 1.5k,, is it a good upgrade? or should i spend money on engine? thanks a lot

can i just ask a stupid question, i never know r32s have g sensor, what is it for and where is it located? thanks

hello everyone, i recently got a 1990 gtr r32, and I'm having some problems with it. 1. extremly bad fuel consumption. my r32 can only do 3kms on 1 liter when I'm driving very gentle(shifting before 3k rpm). the car is slightly moded, according to the previous owner, the engine was rebuilt(with stock parts i think), kakimoto exhaust, custom turbo downpipes, apex intakes, boost restricter off, boost on 8psi, hks intercooler and stock turbos. after i got the car, i put new ngk sparks in, and found the tip on those sparks i took out are really black(fuel), so i checked injector, but they are fine. my question is will it be the o2 sensors, fuel pressure regulator, fuel pump or fuel filter? and will a flashed ecu do this?(previous owner don't know if its flashed or not) 2. hicas. the hicas light on cluster comes on after a few km drives on highway, but goes away if i shut the car off and start again. if i jack the car up right after the light comes on, both rear wheels can be shacked right and left by hand, almost like the hicas is not doing anything, but if the light is off, wheels are perfectly good. my question is whats wrong with my hicas? i already ordered the hicas lock bar, I'm gonna install it either way, but when installing, is it better to take the whole hicas system off from the car or can i just loop the hydraulic line? 3. rear differential. my rear differential makes very big noise when wheels are turning and i happen to find a $300 used one for r32 from getjdmcars.com, its not here yet, but my question is, does the differential on r32s break ofter? should i upgrade it to a cusco 2way or 1.5 way one? thats all questions i have now. thanks for viewing and answering.
