2001 Porsche 996 LS1 Conversion Thread by 1dirtyZ

got to spend some quality time in the garage today 

first off i got the water temp adapter fitting back from the machine shop, this will enable me to fit the porsche sensor on to the LS engine's head :

also got the new shortened powersteering hose and installed that in , which fit great by the way , and i also mounted the pump and bracket to the head, but more on that later 

and the new trigger wheel came in today, just need to drill it and mount it then make a brace to hold the sensor :

after that i installed the sending unit gasket and tightened the retaining ring, so now i can call the fuel system completly done 

i also connected the tail lights and noticed that the work funny; as soon as you cycle the ignition the inner most light works and does not go off and they are very bright ( brake light ), if you turn the lights on the lights the center ones come on and when you turn the fog light on the outer most come on, but the brake pedal does nothing (could be that i didn't connect the switch ) .

can some one tell me the assignment of the lights in a turbo tail light? 

then i decided to start filling the cooling system and power steering ( bad idea ) coolant went smoothly with no leaks , and so did the powersteering up untill i started it and then it started leaking from the connection from gm line to the porsche line, specifically the porsche connection where the hose goes into the end peice . it seems that the engine fire ruined the oring that seals everything . i managed to fix the pressure side ( well at least i think i did ) but could not do so on the return side.

here is what i'm talking about :

anyhow , i started the car and it had its first little leakypoo

01.29.11

02.14.11

i didn't get to work on the car very much lately , been busy with the camaro and work and other stuff, but i did manage to mess around with the intake tubing for a change 

i decided that since this car will be N/A for the time being , then F/I once i get all the bugs worked out , why not build an intake tube that will work with both setups. i was planning on running one tube to the side and slap a filter on it , then i thought , why not TWO ! 

so the plan is to make a Y ( more like a T) right in front of the TB that branches tot he sides and goes where the intercooler outlets would be . and since there are no intercoolers , thats where i will run the tubes to and connect the filters at. this way , when i put the intercoolers on , its just a matter of connecting them to the intake tube 

anyhow , here is what i got done:

fist off i got a 3" dia. aluminum U bend and cut it in half , then scalloped the top part to but the two halves together:

i then fired up the tig welder and set it to weld alu. and proceeded to weld them up to make the Y :

and here's a close up of my handy work

and thats about it 

i think i still have to add a few bends so it better fits in the engine compartment , but thats for another day 

other than that , the battle to reclaim my garage from the mess i made is progressing well: i managed to clean half of it 

( it more like like an archeological dig rather than a clean up: i found stuff from '99 )

02.19.11

not much progress made , but i did manage to connect the alternator and now its charging but right now i have an issue with the alternator light ( charging light ) not going off in the dash : i know the porsche uses two wires tothe alternator : one is the charge indicator and the other is the signal , i tried connecting them and i still get the light in the dash ,,,, marky i need your brains 

another thing i'm messing with is the oil pressure guage in the dash; i can't get it to work from the schematics i have the sensor has two wires going to it : one is the pressure signal and the other is the pressure switch ( low pressure warning light) and the sensor is self grounding. why is not working ?

another thing that got me confused is the driver side window , the window rolls up and down ok but i can't get it go down all the way , it always leaves about an inch of glass showing when you roll it all the way down ( as opposed tot he othe side where the window goes down all the way ) . when you roll the window down all the way it hits a stop at the end of the rail, i know there is an adjuster screw on there but that screw is only for adjusting how far up the window goes. any insight would be helpfull 

other than that , nothing much going on , i'm going to remove the powersteering hard lines when i get the car on a lift again and solder on some propper JIC or AN fittings on there instead of the leaking ones i got there now. that should put an end to the power steering delima 

also on the to do list is the front main seal , which is still leaking ,,,, because i still didn't fix it

i thought about it , but there isn't any as far as i could recall. either way i'll be grounding the sensor tot he frame with a wire as soon as i get back into town .

and since i was on a road trip all by myself , i had alot of time to think and reflect on the project the only thing stopping me from driving the car around is the leaking front main and the power steering line , if i finish those i can drive the car and monitor how well the cooling system works and what not . 

so the plan now is :

- fix the main seal 

- fix the power steering hose 

then worry about the other stuff 

on a side note ,after reading a thread about it in the FI section , i ordered a set of stainless turbo headers for a ford 5.0 (cost a whopping $120 ) that i will be modifying to fit on this thing - talk about focusing on the current issues
