Default Oil Pressure, Injector & Anti Roll Bar Query!!

Dear All,

My car is mivec 1.6 wira, just change to 1.8 block and overhauled... previously i m using 10/40 semi syn oil (Hi-force) and the pressure reading is between 4~9kg... now i m using 5/50 fully syn (Hi-Force), when i step the pedal till the end, the pressure is 11kg...

1. Just wanna double check, will it affect my eng rev like slow it down? or it is just a common reading? should i install a oil catch tank, just read it from some hong kong mag that it can reduce the oil pressure... true?

2. Another mech told me that my ori mivec 1.6 injector is not suitable as now became 1.8 block, he advise change to gsr injector with a emgine management system, he also mentioned that now my engine definitely not enough fuel, must avoid mivec open otherwise BLOW!!, really? one shop quoted gsr injector rm350, kinda expensive right?

3. Anti roll bar, or some said sway bar is controling body rolling left right while cornering right? but some people just said it doesnt serve this purposes??? As my car is ori 1.3, although i changed the rear chasis to mitsubishi, mech still told me that i cant install anti roll bar as my car doesnt have a so called "clip" what is that all about? does it mean that i can't install it at all??

huh..............!!!!!!!!!!!! what pressure is that.........over 120psi, abnormal pressure it's pressure relief valve stuck,,,, that's normal if the oil more thicker means resistance increase so pressre add on........but lubrication is fully at all.......if u is turbo charger engine dun try to use wide range viscosity engiune oil is will cook at turbo

1) oil catch tank can reduce oil pressure??... what kinda oil catch tank is that??...

2) yes... ur mivec 1.6 injectors would not be sufficient to support ur current 1.8 mivec setup... go for gsr injectors or perdana injectors... and yes, u need piggyback ecu such as safc or emanage to control the amount of fuel injected as ur injectors are larger now, ur stock ecu cannot support...

3) antiroll bar reduces bodyroll... means it reduces ur car from leaning on one side too much... antiroll bar reduces bodyroll... strut bars reduces bodyflex....
the clip ur mech mentioned is the bracket to hold the antiroll bar at ur lower arm bar... it is recommended to get the full set rear antiroll bar from wira 1.6/1.8 including the lower arm bar.... welding the antiroll bar to ur existing lower arm bar is not recommended

mivec injector is 240cc, and perdana also 240cc so no need to change to perdana one. the one u need is gsr 390cc injector (MUST install resistor pack - cost around rm30 at chop shops - if NA ecu runs turbo injectors without resistor pack, u will FRY ur ecu). u can find the gsr injectors for cheaps, especially gsr owners that upgrade to bigger injectors, sometimes u can get them for rm100 if u nego nicely.

anyway, what u mean by changing the rear chassis to mitsubishi? potong sambung the body ar?

at high revs if ur car feels jerky or not revvy enough, there is possibility that fuelling is insufficient...

best if can use fuel pressure gauge to measure...
