this is engine in car

 

here is a close up

 

this is the headmen headers and gas line made at earls in indy

 

gas line connected to top fuel rail

 

here is the bottom

 

this is the top radiator hose with 3rd gen radiator

 

passenger side. you can also see the heater hose comming of the fire wall.

 

here you can see power steering resivor and headers

 

95 corvette bellow if you want to keep factory air intake

 

this is other side view. you can see where i pluged the line that comes off the water pump on drivers side. for the lower radiator hose i used a universal. it fit good at the bottom part of the radiator. but when it connected at the water pump i had to cut about 2 1/2 off an old hose and slip that part over the pump and slipped the universal hose over it and clamped it down.

 

these are the heater hoses off the fire wall. the hose on the left goes connected to the front outlet tube that turns up on the water pump. the one on the right is the one that runs on the hard line and connects to the outlet that is side ways on the front of the water pump

 

Lookin good man, nice job. One suggestion though, host those photos somewhere because all but 3 are going to get taken down.

On another note though, do you have any photos of how you did the power steering?

 

yes i have pics on the power steering. but i have to make them smaller. i guess there two big and it won't upload. and i also have some of the other pics of the wireing but there out of focus. i used a disposable camara and it sucked. thats why i haven't posted them. why are they going to take the pics down?

 

Yeah they usually only leave up three if you post more than that as attachments. Check out ls1camaro.net, it has free hosting. Then you can post as many photos as you want to.

 

Your swap looks a lot like mine. Congratulations! Do you still have the part number for the corvette bellows. I think I may buy one to use with ram air.

 

Looks nice.

Admin has a little thing about no more than 3 attachments or something. Bandwidth. Rather, host them somwhere else like imagestation and link them or something.

 

nice looking swap, mine is about to be finished but the end result is a rats nest over top of it , not enough time at the current location to make it look pretty, but oh well. GOOD JOB !!!!

 

where did you get you fuel lines and fittings and how much were they?

 

Thanks. i didn't know about the pics thats cool anyway. this is the part # for the corvette bellow 25147192 duct asm. it cost me $56.85 tax included at the dealer. the fuel lines i got at earls in indy. they can make you any type black,braided etc. mine cost me $61.87 tax included. there number if intrested is 317-241-0318 got a quick question. i was checking the voltage on my throttle position sensor and it was reading 1.22 and as i open the throttle up it went up to 6.22 in the service manuel i have it says it should only go 4.5 to 5.0 volts the this mean the tps is bad?

 

no, it just means its no positioned correctly on the TB. If you look at it, the two mounting holes are slotted. Turn the TPS until you get the right readings.

 

Nice clean swap. :hail:

 

Congrats!!! Now...hows it run????????

 

well the car is not running right it still chokes when i give it gas. i cut the slots in the tps like you said and moved it close to the voltage which was at 6.30 to 5.33 but it wanted to shut off on me. when i started it the idle was real high. after i drove it for a while the idle went down. the rpm needle was going up and down like it wanted to shut off. so when i got to work i put it back where it was. the rpm needle still went up and down but not as bad. it was doing this before i moved it.

 

I don't think it was me that suggested the tps thing. Did you double check the spark plug wire routing?

 

no it was texaslt1 who suggested the tps. and as far as the spark plugs wires go they haven't been moved.

 

Got any vacuum leaks anywhere? Check the IAC?

Thanks for the tip on the corvette bellows, I think im going to do that but I need to find a dual snorkel setup.

 

no problem. what is the iac

 

Idle Air Control unit

Its right under the throttle body near the TPS.

 

Sounds like the opti is crapping out. Any codes?

 

What are your IAC counts at idle?

Anyways, my original intent in posting, I think you should consider swapping to a water pump from a caprice LT1. It will allow you to cleanup the heater core hoses and run the steamline from the back of the heads next to the intake on the passenger side to the expansion tank...then the bottom of the expansion tank can just feed back into your lower heater core hose through a T (just like the 94-96 Impala SS LT1 and Caprice LT1 and L99 engines)...the 94-96 caprice has a very similar engine bay layout to a 3rd gen in terms of where the heater core is and where the expansion tank is...especially when compared to a 4th gen which is very different. I think your swap looks great, it'd just look a little better with that water pump on the engine and the hoses routed a little differently. The caprice pump will have both heater core outlets on the passenger side of the pump where they are intended to wrap out around the belt and accessory bracket to real close to the expansion tank, then they both head back towards the firewall to the heate core, and like I said, one of them has a T with the hose from that going to the bottom of the expansion tank. The steamline from the back of the cylinder heads should just connect to the top of the expansion tank...GM had it go to the throttle body then the other side of that went to the top of the expansion tank...but you don't need to run hot coolant through the TB.

FWIW, if you look at a 94 Caprice or Impala SS, you will see slightly different routing, (extra hose from the top of the expansion tank to the radiator) but GM had a recall on the 94 setup and all replacement parts for 94's as well as factory setups on 95's and 96's are laid out exactly as I described above.

 

part number of that upper hose or car it was made for?????????????pls car,year and engine size ....THANX!

 

sounds like it could either be IAC or Opti. The TPS was definitely part of the problem if you were getting 6+ volts from it. But I would check all of your wires, all the plugs, make sure the IAC is functioning correctly, and see if you have any trouble codes.


Mike - I definitely like what you posted, I'm going to have to check into that.

 

Easy way to check opti is see if you got spark coming from the coil. If so, that can be ruled out. Check to see if the opti is giving spark to the plugs.

 

thanks i'll check the iac. but i don't have a way of checking my codes because i spliced the tan aldl wire from lt1 engine harnes to the organge wire of my camaro's aldl port. is there away i can check it?

 

Not sure, I scan mine using datamaster. Me or texas could hook you up. If I were you I would definatley invest in a cheap lap top if you don't have one already and buy a cable so you can scan your own vehicle and even tune it.

Would grounding the ALDL work still? I have never tried it.

 

did you use your third gen port or the forth gen port? and did you hook up your wires the way i did?

german-sport the hose your asking about is a 93 z28 top radiator hose

 

I kept the original thirdgen ALDL port. I only wired 2 wires from the pcm to the port, one labeled "DATA" (which may be the tan, been a while since I looked) and another for the ground. I imagine if you did both the troubles codes will still work as long as you wired the "service engine" light to the PCM. Something I didn't do.

 

yea thats the one i have hooked up also. and i don't have the service engine light hooked up either. i might have to do that.

 

I've never hooked mine up. but I usually have my computer hooked up to it about 75% of the time I'm driving it when I'm home, so its not that big of a deal.


and I also kept the original ALDL connector, just rewired it.

 

just finished taking off the iac. i cleaned it off with carb cleaner (only the spring and stem). it had carbon build up on it. it was pretty stiff when i pushed it in and pulled it out. but i put it back in. i might have to change the tps and iac. just to be safe. did you just wire up the tan off the lt1 to the orange wire of your cars aldl?

 

The opti can still thow a spark when it is not functioning correctly. The engine will often stumble and misfire when running. Your best bet is to figure out a way to pull the codes.

 

The wire you connect the tan wire to is M in this picture (on the back of the ALDL port of course). You also connect the ground to the one right above it. I don't remember what color it is and im in my boxers not about to go outside and check .

 

Very true. I had installed my Opti about 10 degrees off (don't ask) one time, and it still ran, really ****ty, but it stumbled real bad down low and and had a bad miss up high

 

when i drive the car it run's ok. no stumble or miss. it only does it when i take off from a dead stop. i can't punch the gas pedal. when i do try to spin the tires i can't just punch it. i have to rev up the rpms higher then normal. when it sits idle the rpm needle moves down a little.

 

actually sounds to me like a MAF problem. one of the wires broke on mine and it would stumble and die from a stop, but once you were moving, it ran decent, still not perfect but it ran. Might want to check that.

 

Unplug the MAF, should run off speed density then. If it runs fine off the MAP then its the MAF. Good way to tell.

 

i thought the maf was the problem. i bought another maf and tried it and it did the same. if i unplug it run's with no stumble and when i plug it back up it stumbles again. and thats with both maf sensors. but i'll look at the wires on the maf to make sure that nothing is broke or cut.

 

Something wrong with the wiring getting to the MAF then.

 

i checked the wires and there ok. so i'm stuck again

 

:hail: sweet.
