nice so far-- i have a 84 930 and its getting tired a LS conversion would be nice..

 

Your build helped inspire mine. Thankyou

Of course your is more complex with the wiring, and I've paid a shop to do most of my work.

 

your facebook link is dead

 

cartel, "just do itttt! "

metalman , the link doesn't work

and now that i look back at it , it was not that complex after all . guess it was intimidating at first , but now its more like cutting a connector here , splicing into a few wires her and BAM! you're done

 

did i also mention that the short block is now a longblock
i just need to slap on the rear cover and call it done !

 

i have 2 LS conversions in progress now-- thats all i need is to rip apart the 930 as well

but it would sure be a fun car with 500hp and not worrying about the pancake motor cost to rebuild!

 

Weird, I have it set to public.

 

cartel , listen to that little voice in your head !

metalman , that looks killer , what rear subframe are you using?

 

Thats a narrowed Vette C5, 997 trans, one off adapter, LS4 engine.

 

Kick *** build!

 

progress report !

dropped the car off at a buddy's shop to have him tune the idle surge, calls me up after a few hours telling me it made 378 to the wheels !! and that it idled quite nicly and pulled real smoth and hard .
he then proceeded to tell me that it was not what he expected from a 6.2 and l98 heads ,,,, to which i replied that is was the "***** 5.7" that i built ages ago with 5.3 heads that were somewhat ported ( read porthed a few ports , got bored, decided that those would do ) . needless to say he was surprised

he just has to do one more thing with the cold idle , and then he will add some more timing cause he thought this was the other motor and only put in 22 deg of advance .

sooooo if you figure that it made 378 at the wheels , at the flywheel @ 15% loss that would come out to be just under 435 , which is higher than the output of the original porsche engine of 420 . but that is not my target , i want 420 to the wheels!!!!

anyhow i'm waiting for the guys to send me a video of the runs so i can post it here .

 

Very nice, glad to see it coming along well!

 

progress !!

well i guess i have a few milestones to celebrate
after dynoing the thing ( will post the vid soon ) i took the car over to have the AC done. i dropped the car off at a well known shop and told them "fix it " the guys did a great job, and the owner recomended a different style compressor than the one i got , so i went with it and he did the necessary fabrication to the compressor mount as well as cleaning the whole system before installing the new lines.

well after that i took the car over to the upholsterer for covering up the rear shelf area and fixing the airbag cover, which they did quite well!

i already put a few fun miles on the car for "testing " reasons
and just been finishing a few little things here and there since i'm a bit motivated now , i already jacked the rear up and went under the car to see where a small water leak was coming from , turned out to be a loose clamp on the heater hose. also insulated the ac lines coming out of the compressor because of their close proximity to the headers and muffler.

there are a few issues i have to take care of now , first off the rear cover release isn't working , i remeber fixing it with the old harness but i'm not sure what i did so i guess i have more wire tracing to do

also noticed that the AC belt is off one tooth , so i have to realign the ac bracket to get it in line.

another thing i have to do now - which is quite new for me since i never worried about the AC system in anyof the conversions i have done before - is wire the ac signal to the pcm to bump the idle when on and turn the fans on too.

and a bit of bad news to report , i think all the "testing" is taking its toll on the clutch: i think i smelt some roasted clutch today

anyhow, the list of things to do for now is :

- snap pics
- trace latch release wires
- wire ac signal and check
- install rocker panels
- remove whats left of the old stereo
- take car over to get new nav/stereo system installed
- take it to get detailed inside

 

Im getting anxious. I have been reading this since the beginning of your project a couple years ago. Good luck!

 

more updates

i did snap some pics :

here is how it looks after painting the wing and bumper:





and here is the interior work they done at the upholsterer, airbag cover mounting :



how they mounted the DME and fuse block tot he shelf:



and how the shelf looks installed :



and how it all looks whith the carpet installed :




i also fixed the rear hatch release , turnes out it wasn't getting a positive signal (the release switch up front just grounds the circuit and actuates the release) because the positive signal comes from the spoiler ( retracting and extending ).

also checked the AC signal wire and spliced into it and connected it to the LS PCM , now when ever the AC kicks in the RPM should bump up and the fans kick in ( i say should cause i still need to to adjust the AC on idle parameter )

and i finally got around to installing the rocker panels , which i forgot to take a pic of


so right now the dwindeling to-do list is as follows :

- ac bracket alignment
- remove old stereo unit
- take car to get new stereo unit installed
- detail inside of car
- tune ac rpm and more timing
- check why pass low beam not working
- rear wheel alignment
- check speed sensor wiring ( i think i have the brake wear and speed sensor wires confused)

 

well not much to report but i did put some more miles on the thing and thought i'd share my first ( well sorta first) impressios of driving the thing.

first off the car rides smoothly , it soakes up bumps and imperfections nicely which really surprised me. and i really like how it pulls under WOT .

-the throttle pedal is a bit on the heavy side - no wonder since the cable is about 4 yards long and snakes its way around the car body. this coupled with the small flywheel and huge *** cam i have in there make for some interesting slow launches from a dead stop.

-the thing needs more low end torque just off idle , the 5.7 engine and huge cam ( something like 24x duration and 64x lift ) and low mass flywheel and clutch make moving from a stop a bit difficult , you need to spin the clutch a bit to get it to move without bogging . i guess that the new engine combo shouldn't be as hard to launch as this given the new cam ( cheater cam ) , bigger cubes , and a heavier clutch (dual disk setup).

- car has an issue with ideling with the AC compressor on: as soon as the AC compressor cycles on the engine dies due to the load it places on it , when crusing or on throttle its not an issue just when ideling. i still didn't mess properly with the tune to try to fix this , but i did raise the "ac on" idle speed which didn't help. i'm sure messing with hptuners for a bit will have this issue sorted out.

- the exhaust is a bit on the loud side for what i have in mind - its perfectly ok by muscle car standards - but i would prefer it to be a bit quieter. there is a droning sound , which happenes to be the loudest sound the exhaust is when cruising around 2000 rpm , but i quickly dies down when you pass 2300 rpm. guess thats the price you pay for a free flowing exhaust .
i'm not worried about it right now since the new engine will have lower compression and turbos to muffle the sound even more.

- i still have to get used to driving such a small car !

- steering is on the heavy side , its totaly managable being without power but i'm starting to like the idea of turning the wheel with one finger

- i also found out the horn only works with the ignition OFF , and as soon as you turn it on you get nothing ?? more wiring to trace i guess

- i finally washed the car and cleaned the inside a bit ( wiped it with a damp cloth ) and it looks better than before i did find out there are a few dings in the pass side sail panel ( around the rear window) that i need to have removed , but thats on the might-do-some-time-in-the-distant-future-list

 

Awesome progress!! Where's the dyno video and vids of you doing a WOT pull on the road?

 

first 1/4 mile test

 

You my friend are an inspiration to all of us DIY guys.
