Hahaha. Once the trans is finished up ill get a video. Hopefully mid next week. Trans is in just need to get the converter bolts in, connect the lines then connect them to the cooler. I Also need to attached the upper rad hose and plug the fan in.

Trans is all finished up. Lines are ran and connecter, dipstick is in, wiring is all done and connected. Hopefully I can get a driveshaft made up this or next week. Should have my buddy coming for the cold side in a week or two. Cant wait to get it down on the ground!

Well not much to update on, been real busy in the yard.
I got the driveshaft in. Stock one actually fit with a conversion joint! Score for this season. Next year im sure ill be stuffing a 9" in so Ill get a moly shaft made.
Exhaust is almost finished, just need to connect the DP to the wheel area. I also have most of the cold side all mocked up ready to be welded. My friend says Friday he is coming over to weld it.

Although it doesnt look like much this was huge progress this weekend!
Cold side is done and all bolted on. Hoping to finish the exhaust this week its really close. Once the exhaust is finished up I should be able to take it for a drive!

Re: Project Déjà vu- 87 Z28 5.3L Turbo
Well the exhaust is almost wrapped up! Downpipe is now vbanded and currently dumps straight down next to the starter. Need to make a few more Pie cuts and it should be all finished hopefully tonight. Actually looking like if I get someone over this weekend to bleed the brakes and maybe put the hood on that I may actually be able to take it around the block. Still have to add in the 4l80e code to the trans then modify the shift tables which I still havnt read up on yet.

Re: Project Déjà vu- 87 Z28 5.3L Turbo
Hey Jay, looking good bro. Is there a reason why the blow-off valve is so close to the compressor? Just asking because that is the first time I've seen anyone put it in that location. By the way I'm no turbo expert, just learning like everyone else!

Re: Project Déjà vu- 87 Z28 5.3L Turbo
I debated it as well. The purpose it to protect compressor surge so it makes sense to keep it as close to the turbo as possible so any air traveling through the intercooler and piping is accounted for. There are TONS of debates on ls1tech, yellowbullet etc on where the should actually be placed. That is the theory I found which made the most sense. Front what I have found is more tuner's and supra guys run them there. My old car I had one before and after the IC.
If I have any issues Ill just add another lol

Re: Project Déjà vu- 87 Z28 5.3L Turbo
Well I havnt updated this much as I havnt been working on the car much. Working on the yard/patio too much on my off days.
I did move the car out of the garage to wash it. Its having a hard start issue. Seemed fine before the trans went in. Now all of a sudden its like 3-4 tries cranking for 4-5sec each. However once it is warm it fires instantly.
It does run pretty smooth though. I did get a log when I got it running and it is showing issues with 3-4-6 coil communications. I didnt have those prior to putting the trans in since I logged it then and had zero codes. Not sure if when i pulled the wires apart to put heat sleeves on did it or not. I may toss some stock wires on and see or switch around the coils. I even went back to the old T56 tune to see since it wouldnt run for more then 5 seconds with the 4l80e tune in. My buddy said to see if i have the VSS' backwards. Im fairly certain I plugged them in right.
Im gonna grab 20L of 91 octane tonight to fill the tank up just to rule out that. The tank was fairly low and just old 87.

Re: Project Déjà vu- 87 Z28 5.3L Turbo
Its a bummer but ill get it ironed out. In the mean time plugging away at small jobs. Last night I tossed the air damn on, put the side gfx brackets in, worked on the gas pedal and got it set for the LS1 cable and I made a Bracket to hold the PCM, which I noticed the blue connector was half out! Also filled half the tank. So when I get home im gonna try again and see. Im starting to wonder if I pinched the Cam wiring when the trans went in.

Re: Project Déjà vu- 87 Z28 5.3L Turbo
I think i got it for the most part figured out. I yanked the downpipe, pulled the plugs that were giving me coil issues. Cleaned them, installed the wires (im thinking they wernt on snug) car fired right up. I waited about 5 min and tried again with success. I suppose the real test will be when I get home. I got a quick log out of the car and pulled fuel where it was idling.
Down to only the P0342 Cam circuit low code now. I'm glad I basically put everything that can be in the way of the cam sensor, in the way LOL
I also seem to have a hung up idle or there is some sort of warm up being added to the desired idle. I was getting an idle of 1450rpm. I have it set for 1100 then ramps down to 800 when "warm"
I cant seem to get my damn Speedhut tach to work either. The Tach output on the PCM is fried (was like that when my buddy had it) so i tapped into a coil wire but im still getting no reading. then when i hook the resister/power to the signal wire the needle jumps all over the place.

Well seems to be running and idling great now! The cam sensor must have been something in the pigtail. maybe they were not tight enough etc. Now I just need to work on the fueling/spark. The timing is a bit much for an ls6 cam. Im hoping on the weekend sometime Ill take it around the neighbourhood.

SWEETNESS! Looking forward to results. Go easy on the timing now if running pump fuel, REAL easy.... like 8 and bump it a little at a time, but you already know that dont ya?
20lbs GO!!!

Re: Project Déjà vu- 87 Z28 5.3L Turbo
Ya only plan on starting with 4psi and working on the tune slowly. I doubt it will see the track this year. Easy to get greedy with boost! my buddy was spiking 24psi on pump 91 on his forged 370 (the tune im using as a base) No wonder why he kept melting down cylinder heads LOL

Re: Project Déjà vu- 87 Z28 5.3L Turbo
From my homework it sure seems that PSI isnt nearly as dangerous as too much timing with sbe stuff and boost, ESPECIALLY with a tight cam like stock or LS6 etc.

Re: Project Déjà vu- 87 Z28 5.3L Turbo
Went for a 5min drive and still cant wipe the smile off my face! only saw like 1.2psi but I wasnt out to tune or beat on it, just making sure it went through the gears and drove fine.
Drove amazing. Shifted great, made awesome BOV sounds lol. Actually amazed how loud a GT45 is. Sounds similar to a billet turbo.
Only issue is I still do not have power steering! Pump doesnt whine or nothing. I had the car on stands, moved the tires lock to lock like 30-40 times with the car off and at least that many times with the car running. I know If I turn the wheels by hand I can hear bubbles in the steering box. Not sure if maybe one of the orings is allowing air to seep in? No leaks etc. Im running a 4th gen upper rad hose cooler as well.

4th gen pump? Notorious for over heating and blowing fluid out with the divorced reservoir/pump arrangement. Mine whips it up like butter if its filled to spec.... If I fill it RIGHT to the top it seems okay. No leaks either

Re: Project Déjà vu- 87 Z28 5.3L Turbo
Well ordered up the metric oring to AN adapters for the power steering. Hoping they make it to my house by the weekend. Doubt Ill be that lucky. Looks like the line that comes out of the box to the resevoir (or in my case the cooler) has a very very small leak. doesnt seem to be enough to make a mess just enough to make it a bit wet. My guess in it is pulling in air there and causing an air pocket trapping the fluid from moving. I ordered all the fittings (box and pump) but will probably just make the one needed line for now since its a low pressure line. If its fixed up by the weekend I will get a video.

Re: Project Déjà vu- 87 Z28 5.3L Turbo
Just noticed the other day I never really posted a finished pic. A few unfinished things but for the most part done. I have my new power steering line ready to go for when the AN fitting comes in. Summit seems to be taking forever to ship to Canada. Generally I ship to Detroit and take the 10min to go pick up my parts but it wasn’t worth it for $25 in fittings.

Re: Project Déjà vu- 87 Z28 5.3L Turbo
Power steering works!!!! After changing the lines, trying to bleed just the box, then the entire system twice. I decided to order a new pump. Well upon pulling the pump all apart so I had my core with me for exchange I happened to look at the feed tube from the reservoir to the top of the pump. Well the guy I bought the accessories from put a 1/2" or so rubber cap in there so nothing would get in! So thrashed and got everything back on, pressed the pulley back on etc. Fired the car up BAM steering works!
Hoping to get some footage of the car this weekend for you guys!

Re: Project Déjà vu- 87 Z28 5.3L Turbo
I doubt it will see any track time or a dyno this season with the stock rear. If anything just a street tire pass. Pretty busy with a newborn so the car will just be for random friday/sat night blasts around town. We have one local dyno, unsure if it is even open any more. It use to be owned by friends. Not sure where it has gone since.
Plans next winter is to get a 9" and some billet specialties or RT'S depending on what my winter budget allows lol

Re: Project Déjà vu- 87 Z28 5.3L Turbo
That's essentially what I've built mine for. I'm getting a little tired of searching for E85 stations however. I may switch to 93/Meth inj. I had some really good luck with the black Friday deals as far as large purchases go. Bought my 9" housing with free shipping and 10% off. That's what I would do to save you a few loonies! Haha

LOL loonies. Ya I probably will do the same. Last black friday I saved a fortune on my gates and injectors. Money was at par also which helped. As of now with our dollar so low I wont be making any big moves lol
Plans is a Back braced Quick 9", Yukon Aluminum center, 3.25 and debating the locker or tru trak 35 spline. 90% street driving tells me tru trak, wallet tells me locker lol

That's essentially my exact specs except a moser back braced housing and 3.50 gear. I run my car 95% street driving with a spool and 35 splines. No issues, drives fine. I do have a 28x10.5 on it though.

I did the spool think on my last iroc and refuse to do it again lol.
Well just got in from a 30min cruise. Ripped around with the wife and scared the **** outta her in low boost lol. Super rich WOT. Of course my laptop died as soon as i hooked it up. Im gonna have to get an inverter.
Everything checked out great.
170ish max ECT
170ish trans temp
190ish Oil temp
48psi oil pressure idle hot
100 degree iats
Only issue im unsure is when rolling out of first at like 5% throttle i fet a slight shake/screech. Really hoping it isnt trans related! fresh rebuilt and new tripple disk converter.
Ill get it back out this weekend and get a video.

Well just got in from a 30min cruise. Ripped around with the wife and scared the **** outta her in low boost lol. Super rich WOT. Of course my laptop died as soon as i hooked it up. Im gonna have to get an inverter.
Everything checked out great.
170ish max ECT
170ish trans temp
190ish Oil temp
48psi oil pressure idle hot
100 degree iats

Re: Project Déjà vu- 87 Z28 5.3L Turbo
Well drove it around last night and finially got my laptop to connect. Damn windows 7. So this morning I took her to work! Said to myself, only one way to find out if its ready! Drove mint. Pretty well a 10 mile drive mostly county roads but was nice to see everything logging good. I think the exhaust if giving some false knock. I see 4 degree's right away which was kind of expected with the exhaust touching the frame rail.
The chatter sound is there there. Definitely from the converter. Im thinking it may be locking all the time. I tried manually locking it cruising but didnt notice a change. Gonna see if there is a PID i can log to see when it locks. Maybe I will snip the wire after work and see. The 4l80e wiring had me a bit confussed bc I started from scratch and some of the colouring was off to what the diagrams showed. Maybe the TCC is wired wrong. Or even the TCC relay I wired is wrong! (literally just though of this while typing). Thirdgen is the opposite signal as LS stuff so i had to feed the PCM negetive instead of positive. Maybe it didnt work? Worth yanking the relay for now to see.

170*F ECT sounds great. What are you using for radiator and thermostat? I have a stock IROC radiator and stock vette thermostat in mine. I am normally around 195*F when driving, and it will get to 205 after extended low speed driving or idling. It seems to be more RPM related than ambient temp related.

Stock 1987 Rad and stock Single fan with a 160 degree stat. I did see a spike this morning in the drive thru up to 220 degrees. May have a small air pocket still. As soon as I touched the gas it instantly dropped to like 180, then when I hit the road doing around 50mph it dropped down to a solid 164-168 degrees all the way to work . Mind you it is only around 55 degrees here in the morning. We still havnt seen our normal humid summer yet. That will be the real test. We get lots of 95 degree feels like 125 degree days in the summer lol.

Never thought I'd be back on this forum. How's it going Jay? This car looks amazing. I've sold off all my Mustang stuff and I'm debating another 3rdgen, lol! After seeing this clean example it might have swayed me enough to go out and grab one. The stance of your car is great, would you be able to PM me the details about the suspension? I should have just kept the 87 I bought from you and finished it. Hindsight, lol!

Re: Project Déjà vu- 87 Z28 5.3L Turbo
Thanks Steve! Gotta get back into one. Maybe ill sell you this one too LOL
So for a small update. I have the tune pretty well dialed in. However that trans sound is still there. Seems more prominent after doing a pull. I decided to yank the trans to check the flywheel bolts since I forgot to grind the powdercoat off the TCI unit. After I got the trans out of the way I checked the bolts and the seemed fine so I doubt it will fix anything. Im gonna drop the pan and check the filter and make sure my dipstick is reading correct. Then if the sound is still there I will be going to my trans builders place. He told me to bring it by on the weekend.
While its up in the air I will do my 70km oil change too LOL. Figure you can never be too safe with a unknown shortblock. Figure since the first few pulls were in the 9.0 AFR range I may as well dump the oil for some fresh stuff. Will be sure to update by the weekend. Maybe Ill get a passenger soon for some video

Re: Project Déjà vu- 87 Z28 5.3L Turbo
Well took it out for a good while on Saturday with some 90* temps. Everything was great. So great that when i went to my trans guys place the entire way there then to my friends place the car trans or whatever it is didn't make a single noise. Drove with the trans guy for around 10min doing all slow speed stuff and nothing. Then I leave my buddies house after a few hours and the sound is back. WTF.
Currently debating rear ends 8.8, 9" and tire/rim combo. My idea was to stick with a 4th gen spec'd rear end so I could keep the ZR1s for a street setup but I do not like the look of the RT-S rims on a 4th gen rear as you lose the dish. I may still do 4th gen spec and Billet specialties street lites since they look "okay". Lots to think about!

Re: Project Déjà vu- 87 Z28 5.3L Turbo
Well took the car to a local show in town and got some great feedback from people. Amazingly a lot of older guys loved it and had tons of questions. Now I am very torn on what I want to do with my rear end and wheel choice. I was pretty well set on going back to a 3rd gen or narrower rear, selling my ZR1’s and getting with billet specialties or Weld RT-S 15x10 and 17x7’s but I had so many comments on how good the car looks and how no-one ever expected a turbo LS to be under the hood. Now im debating just get a 4th gen length rear and toss a Drag radial on my current wheels. Im still trying to find a unicorn (16” ZR1’s for a slick) but that seems like it’s never gonna happen.
BTW the trans is STILL making that noise and it is definitely narrowed down to only happening during 140-160 degrees trans temp. The car show followed our local parade in. As soon as the trans got to around 140ish temp it started making that slipping/chatter/grind sound. So it looks like my trans guy may have to come to me bc when I get to his place the trans is already around 170s and there doesn’t seem to be an issue then. Seems odd to me that only during a range it happens.

Re: Project Déjà vu- 87 Z28 5.3L Turbo
Awesome to hear that the ride is up and running! I can't think of anything that would cause the sound. Is is something that you could get a sound clip of? Does the does the sound create any harshness or vibration to transmit through the drive train and into the cabin?
I also contemplated a long time before I pulled the trigger on my rear width. I settled on the 3rd gen width as it would allow me to get some dish with some lower offset wheels. Also the benefit of not having to run spacers up front was a major factor. Granted, I had to pick up another set of spacers to run my C5 Z06 wheels, but these are temporary and I hope to get some proper wheels before long.
How is it running? Do you have any finished under the hood pics?

Re: Project Déjà vu- 87 Z28 5.3L Turbo
ya you can feel it in the car when it starts to shake/grind. It has to be something 1st gear related at a certain temp. Same RPM at like 10mph in 2nd gear is perfectly fine. I had all last night to myself and probably should have taken it to the trans guys place.
Yup thats the kicker, I want a dished wheel so bad! and really wanna part ways from the adapters, even though they havnt caused issued. Debating the CCW Classic or Weld RT-s or Weld S77B's but its a big pill to swallow. Billet specialties Street lights are priced pretty good, but im still not 1000% sold! Im sure thats the route I will go.

Re: Project Déjà vu- 87 Z28 5.3L Turbo
I really dont want to go over $1500, but give or take is fine. Im debating buying the fronts first, then waiting out on what im gonna do with the rear end then purchase the rears then since they are a bit cheaper.
Racestars- $900ish for 15/17
Billet specialties Street lights- $1100-1200 for 15/17
Weld RTS S71- $1700ish 15-17
Weld RTS- S77b- $2000ish for 15-17
CCW classic 2 piece is also in the $2000 range.

Re: Project Déjà vu- 87 Z28 5.3L Turbo
Starting to lean towards converter issues. I have been in contact with RPM Transmissions (who supplied the PI triple disk) Shane there was saying it could be due to the fact that triple disks can be noisy and I have a quiet car. I would like to think its an issue as you kinda feel it slip. Brought a buddy for a sold 2-3 rip yesterday. I must say for 6psi the car moves real good. Shifts nice as well.
I have also contacted Precision Industries and the guy I bought the converter off. Maybe they can transfer the 5 year warranty over to me since i bought it brand new from the guy. I may toss my buddies stock 4l80e converter in just to make sure. If its solves the problem, I may just finish the year off with that in the car and send the PI back to them to look at and have it restalled. I found out it was spec'd for a 427lsx blower car so its really tight on my 323ci turbo setup.
