1995 saturn mod
ok. my first issue.. this car was complete crap when i got it.. its a 95 sw2 now basically a sw1.. since i had a 97 engine and 95 auto trans from my 96 sc1 that ran, car was wrecked and falling apart... anyway after i swapped to single cam got pcm. i was getting 33 mpg with a blown up dohc. now 22 mpg with sohc, i'm confused.. no check engine light...
now i've modded the intake to reroute between radiator and exhaust manifold using a 1994 saturn dohc intake.. they were changed in 95. moved IAT to where it sucks in air. keep it warm.. disconnected o2 sensor.. i was told when sensor warms up it mostly only goes by that.. . i'm also planning a mod on the fuel pressure regulator.. at no throttle theres more vacuum pressure.. i'm getting a vacuum ''check valve'' and a vacuum ''tank'' and i'm going to hook it to the regulator. to keep low psi. this is experimental so i'm not sure if it'll work right. had a thought of connecting MAP sensor in that as well. might put a 110 ohm resistor in place of IAT
