roger, given what i read about these engines ( i don't recall if it is the 3.4 or the 3.6) ,,, its just a matter of time

 

How's that rear quarter attached? These cars need more curve like the classic 911's (964/993) and I've been looking at aftermarket wider quarters but I wasn't sure how much bode work is involved.

the whole rear quarter is one peice and is welded to the pillar.
i know there are companies that sell conversion kits ( from 996 to 997 - or wide body kits) but they are pretty involved when it comes to installation cause you will be changing the whole back side of the car .

 

Thanks. I assumed it was fairly traditional. It's not uncommon to see air cooled cars with different quarters. From pics online it doesn't appear that the factory turbo or GT cars have that much wider or flared quarters.

Thanks for the response.

i guess you can really tell the difference between a turbo/gt and a regular 996 if you look at them from the top or back side by side .

 

 

Yeah, I see your point. Thanks for digging those up, I didn't know the difference was that drastic.

Well I got my car today, it's in pretty good condition considering what I paid for it. I was happy to find the engine ECU still in the car and that all of windows, sun roof etc work when I hooked up a battery. Even has the CD changer still in it.

Aside from the fab work to mount the engine, I think the main challenge is going to be wiring up the gauges and climate control. Were you going to use the GM a/c compressor, or mate up the porsche unit?

 

Yes !!!

 

LOL 1dirtyz, is that middle pic a picture of a plastic model GT2?

 

LS1-450 ,,,,, no,,,, its the,,, uuuhhh,,,,, its the chinese export version! - they're pretty lax when it comes to details

well brian , where's the build thread ??? you know the project does not exist if there are no pics of it

do you have all the ac controlls inside? if so , just put the GM compressor on there and hook it up to the porsche A/C compressor plug ( you're going to need a GM plug off course ) and just make a pair of A/C lines to route to the compressor ( porsche is in the upper passenger side of the car location while the LS1 is on the driver bottom). that way you don't have to mess with anything else

as for the mounts ,,, you can do one better : use the stock mounts ! just make the plates that bolt to the head like i did and have them bend back a bit and weld them to a tube that bolts to the stock mount ! ( kinda like the mounting ideas i had)

does it still have the tranny?

 

moving on ,, i got some work done last night
i finally got the dash brace out ,,, after many nights and days un bolting and un screwing and looking for hidden bolts and screw , i finally got the dash out , and i have enough bolts and nuts and screw to re build the titanic

here is the after math



and here is what i got out



i was happy i was done with removing it ,,, but then i realized something !! the damn thing is identical to the new one except for the clutch pedal bracket and bolt!!! i could have just bought the bracket, pedal, and a few other dodads and just bolted them to what i had and be done with it ! i guess is should have researched ( and poked my head under the dash ) a bit more



another point in the project i reached and was postponing is the gas pedal deal; the porsche uses a pedal unit that bolts to the ground , and has a cable that runs out of it and up into the dash ,,, which is fine till now and looks promising ,,,,, untill you find out that the cable is only about a foot long and ends under the dash at the TPS sensor !?? why wouldn't you just incorporate the sensor into the pedal assembly ??

here is how the pedal unit looks like :



it basically has a cam inside that the cable runs over , then goes out to the sensor , which has another cam and the cable is attatched to it :



at this point i don't know if i should keep this unit or go with something different , the problem with this unit is that it does not have that much travel , which leads me to think it won't open up the LS1 throttle all the way . on the other hand , it would be nice to keep it and keep the sensor working , and find some way to use them both so i can retain the stock tps signal for later use , plus this being an automatic car before, it had the benifit of a kick down switch built in to the pedal ! you never know when that will come in handy ( finger is pointing to it )




either way the cable routing is pretty straight forward , from the throttle body it will go back and up into the hump behind the passenger seats ( there is a hole already there- just above the intake manifold) and work its way on top of the driveshaft tunnel ( and under the carpet ) towards the shifter , then goes through the center of the dash anturns into what ever solution i come up with for the pedal


anyhow , i'll keep banging my head till i find a solution cause only then can i bolt up the dash .



furthermore, i installed the steam vent tubes on the engine , i'm planning on running two vents ( front and back ) and have them tied together and connct to the puke tank. the reason for that it that the engine sits pretty flat if not tilted backwards ( think hard acceleration ) and having the vents plugged just seemed it would cause steam pockets, so i used two cross over vents front and rear.


i also got the ATI balancer in finally and plugged the oil sensor hole in the block , and bolted in the porsche oil pressure sending unit on to the remote filter thing ( sorry no pics ) and got the shortened thermo. housing inplace , and finished the driver side coolant tube , here is a picture of the finished product in place :



up next on the list :

- figure out the throttle cable/pedal delimma
- once that is done , bolt the stupid dash back in place
- connect the vent tubes together and tie into the expansion tank
- clean and install the intake, fuel injectors, and rails
- finish up the coolant hoses.

 

IMO, that's the correct call on the vent tubes. It can be difficult to get the air out of an LS block & near impossible without the heads vented.

If you ever decide to use an Accusump (pre-oiler), that plugged stock oil sending unit port is a very handy place to hook it up.

 

Are you using a cable operated throttle body or drive by wire? If DBW, why not use the GM throttle pedal.

 

going with the cable throttle , less hassel than the wire pedal and that is how i ordered my harness ( starting to think that throttle by wire might be easier now ) .

 

Wow that's one crazy build! Awesome work!!! Can't wait to see it run!

 

Then I would assume that the stock throttle pedal wont work. I would think that an earlier model (or aftermarket) cable capable throttle pedal will be necessary.

 

the stock one might work if you modify it a bit , i'm just worried about how much travel it gives.'i'm going to fix it in place and properly mesure how much the cable moves and see if i t can work with the throttle i have.
if it doesn't work out , i already have my eyes on this as a replacement :

its lokar's eleiminator pedal unit , real clean instalation and is somewhat adjustable .

but that has to wait for a bit since i'm getting real busy with the camaro cause of an upcoming race this week .

 

More good progress on yours!

Here's my little gem, love the wheels lol! At least I'm all set with spare tires.





I'm running a g96 (non turbo) trans and will be using a KEP adapter. The adapter for this trans is quite a bit more expensive than turbo version because of the lack of a starter boss on the bellhousing. I think it will live with the stock hp/tq of the ls1 as long as I don't beat the hell out of it

The guy at KEP said there is supposed to be a 996 at SEMA with this version of their adapter kit and GM's e-rod crate engine package so it sounds like this may become a popular swap.

I've been looking at some wiring diagrams and didn't see a crank sensor for engine RPM, maybe I missed it. Which sensor are you going to use for this?

 

Great car love the color too
