no take off

[lilrogue78]

Hi I just got this 1992 saturn SL1 SOHC(which Sucks) I want a DOHC and am not sutre how hard it will be to switch over the mechanical part of the process would be nothing for me to do i can do all that stuff but what about the wiring harness?

anyway back to subject This car has shit for low end power and take off after about 3,000RPM she takes right off and will get therre quick i mean i can stop it to the floor with my E-Brake on and wont even squak ires on wet pavement and barely will on gravel but like a said after 3grand she kicks in descetly this car has been sitting for about 5 years the motor got messed up some retard ran it till the timing chain broke which bent a valve which i had to tear the head all apart to replace.... darn people.... but i put new gaskets in and a timing chain and shit and it runs good shake a little at low rpm`s doent seem to have a miss but just wont run right any ideas or suggestions are appreciated thank you

well its better off to buy the entire dohc engine and harness/pcm then to deal with modifying it. those sohc were tbi, and thats the main problem. also its not good to have the wheels spin in a saturn, it causes differential problems. but is it a standard or auto? you need to probably check into exhaust being plugged or a rich mixture, if everything else was fine. those tbi sohc are junk, they didnt have much of any power from factory.

Well i have a code scanner and i ran my data output and its steadily having a rich output also it is an automatic with the performance switch which i still have not figured wtf that does and i know it did sit for about 5 years w/o running at all so did that possibly mess somthin up? ihave never really been a saturn dude so i am still gettin into this stuff i have always been into chevy (cavaliers) or my good old Cutlass Supreme SL with the 3.1 so yea i miss the balls it had maybe its just me maybe it runs fine but i just feel it should have some kinda power even if it is under 3,000 rpms

for a DOHC swap - http://www.differentracing.com/tech_...dohc_swap.html

your SOHC auto trans will not work with the DOHC PCM

the PERF switch increases transmission line pressure, extends the shift points and raises the rev limiter.

your code scanner, does it have a actual display or does it flash the SES light?

did you allow time for the O2 sensor to warmup before checking the reading?

Sounds pretty normal to me for a 92 SOHC ...Did you time it right?, sounds like maybe you didnt? those things are dogs! but if its not timed right it wont run right even 1 tooth off will cause a problem, if the timing is right...only suggestion is to run the living crap out of it, they seem to run better when ran hard...dont forget to change the oil!
and check it often
