Hello frineds,
This is my car 1994 opel astra gsi ,
i bougth it 19.05.2007 when i bougth it it has only chip,ported polished gm head,filter and
i started to load it,
fisrtly i change my fuel pump.i bougth walbro fuel pump and second i enlarged throtle body on cnc(68.5mm) and the car goes very vell
after some time i build my engine and using high degree mechanical profile cams but they did not give much power and my second problem is rev limiter and i use Qrystal quartz for much rev the original is 11.8hz and i changed to 13hz and i can rev 8300rpm.
My old setup;
*wossner 12,5c/r 87.5mm pistons
*forged rods with arp rod bolts
*chip
*ported polished coscast head
*steel caps
*autosprint 285 degree cams
*mechanical tappets
*autosprint bronze valve guides
*autosprint double valve springs
*greedy emanage ultimate piggy back
*walbro fuel pump
*lexmaul intake manifolt
*68.5mm enlarged throtle body
*lexmaul 4-2-1 headers
*enlarged afm
*c20let
injectors@3 bar
*plx r300 wideband
*bcr7eix iridium plugs
*f20 4wd gear box(3.72 final ratio)
*2,5" exhaust
*obx oil catch tank
*cometic gasget(1.9mm)
*z20let oil pump
*turbonetics cam gears
*tx auto sport cranck pulley
this setup gives 205hp on dyno and 200nm torque but i did not do cam timing maybe it can give extra 5-6 hp my autosprint cams are regrind and they did not give much power and i bougth cams from SBD moto sport they are 305/295 degree and inlet 11.9mm lift exhaust is 11.6mm lift autosprints are 285 degree and 11.3mm lift but when i measure them autosprint lift looks like 10mm
now i install haltech e8 aftermarket ecu and 1 bar map sensor i dont need afm i think this gives me a much power when i install haltech i am using nearly 17-18 degree ignition advance but the intake sound increase i think aftermarket gives me a extra hp
now i am using multi coils ignition system with boch ls1 coils
i think if i will succesful on e8 tuning my target hp is 235-240 with lexmaul intake.
