ok..well got the driver side in, wasnt that hard until the bolt nea the beack of the engine was to get in and now my o2 sensors are way to short to plug up....is there a way to where i can splice them and add extra wire? or when i take my car to the exhaust shop for my Custom Y pipe they can extend them for me?
please let me know..thanks
randy
also i am starting on the passenger side right now...
im guessing the starter comes outt....
let me know guys QUICK

You have to do the splice on the PCM side wire... Don't cut the wires between the connector and the O2 Sensor.

 

starter off and alternator off

As far as the O2 wire. i cut some of the sheathing that kinda holds it with the other wires and then pulled some of the extra wire out so i could plug it in, then used electrial tape and put it around the sheathing (sp?) and was good to go

 

I extended the O2s themselves because I could not see a logical reason to hack up the harness itself, much easier to buy new O2s if it don,t work.
No problems so far, just take some time and do it right making sure your splices are good and wrap the whole shibang in convoluted tubing and it should be good.

 

i 've heard bad things about splicing into the wires on the sensor. I just bought some extenders they're pretty cheap.

 

i thought one of the O2 wires was air filled or something so it can always have an accurate reading to judge off of? cutting and splicing into it will ruin the ability to monitor properly, lol i'm sure someone can explain that better then me
just spend the $40 and get some extensions

 

ok...well i jsut learned that i REALY DO HATE LT1's and LT's...
didnt even get the ****ing pasenger side on and this is my 2nd day...took the valve cover off, i cant get it from the bottom because i cant get the car high enough....took out the motor mount bolt..plus i ran out of daylight...i wish it stil got dark around 8 or 9....well have n e of yall heard of putting the header in from the TOP? i think i can if i remove the heater core lines near the firewall!! if i remove those will it hurt n e thing?
oo also when i took teh valve cover off, they guy who had the car b4 me ran CASTROL in it..now there is GOOOOOO everywhere on the heads, looks sooo ugly...and im probably jsut going to buy the o2 extensions from thunderracing...will thsoe work for the o2's? please let me know guys

i think you will just need the pass. side extension my driver side reached. as for installing it, pull out the motor mount bolt and raise the engine a good inch or more, slide the header up from the bottom the collector should be where the starter was and with the engine up it will fit between the block and the frame into place. i took me two days to figure that out, it wasnt fun. and the car does have to be jacked up a bit to help the angle.

 

get that car as high as you can with blocks of wood or ramps/stands...whatever you have. The next part sounds bad but its real simple....

On the k-member (or cradle) there are 6 bolts that hold it in place, 3 on each side. Loosen the drivers side ones and completely remove the passenger side ones. Jam a big old crowbar and pry the passenger side of the cradle down, if you do all this and the starter is off, and you still cant get it in from the bottom...your out of luck. I wouln't even attempt to do it from the top.

edit: you need to have the pasenger side motor mount bolt out too, then jack up the engine as far as it will go (to the cowl, just dont force it and break anything.

well i did...but tom im just going to jack it up more with my jackstands and my centerblocks.....hope this will work...
thanks for the input, but yea i think my passenger side o2 sensor will connect but not the driver side...can i order extensions from thuinder racing?

Jack the motor up as high as you can, remove the alternator and the starter. Before you put the header in, re-route the ABS wheel sensor wiring harnesses, and wrap any wires that are gonna be close to the headers with heat reflective tape.

 

when we put the headers on my neighbors camaro (96 A4) we had to jack the motor up. The passenger side is a pain in the ****. The effort is worth the reward.

the O2 sensor thing, dont splice them yourself. get the extenders, we tried to splice them ourselfs (soldering and stuff) and it didnt work at all. Just buy the extenders and save money on tylenol.

 

i got the driver side in with no sweat...pretty easy...but the passenger side im about to do...i will let yall know after im done.
