SBC SINGLE TURBO PROJECT

Re: SBC SINGLE TURBO PROJECT
Do I “Need” a kill switch if I relocate my battery?
I may go for a test n tune once in a blue moon, but don’t plan on running it competitively.
The first diagram is the way GM has it
The second is what I planned on doing? (For simplicity sake)
This works doesn’t it?

Re: SBC SINGLE TURBO PROJECT
Well upon further investigation….
looks like if it’s relocated anywhere there has to be a kill switch to run at the track (test n tune or not)
and with that a sealed battery box. No questions asked…
damn, back to the drawing board

Re: SBC SINGLE TURBO PROJECT
So all my stuff came in…
Mounted the kill switch like LB9GTA
Already ran the battery cable to the front where I’m gonna have a positive bulkhead and tie in with the existing cables.
Gotta run the 4 gauge wire from the alternator to the kill switch

Re: SBC SINGLE TURBO PROJECT
K, power wires have been run back n forth.
Just gotta make terminal ends in the back, the front is done.
Another quick question…. I wanna keep my oil cooler and was gonna run 5/8” heater hose but can someone tell me where the coolant was coming from and going to as far as the passenger side plumbing goes .
Getting closer…..

Re: SBC SINGLE TURBO PROJECT
Mounted the Moroso battery box in the hatch.
Made terminal ends on all the wires in the hatch and connected them.
Battery positive and alternator power wire to one lug on the kill switch and the other lug goes to the positive power bulkhead on my driver fender.
Whew…. Still gotta install
Coolant lines from oil cooler
Vacuum lines
Boost gauge
Power to starter from the positive bulk head
MAP
Passenger PVC to catch can
Put the Wideband O2 in.(just a hookup)
Then EBL Flash P4
Plugs and wires/timing
Sooooo close

Re: SBC SINGLE TURBO PROJECT
Well the plugs and wires go in pretty good… if hours is good 🤣
After a bunch of fighting with the lack of space I bit the bullet….
Gotta unbolt the driver side from the head and v-band to get #1 spark plug in, but it might have gone in easier without the header wrap. Either way I feel like the wrap is a necessity so…, it stays
I hate the way the HSR fuel rails fit around the distributor, I might try to route it from the front with the crossover in the back…
I pulled the cap and it looks like I got rough timing ready.
Wires routed this way for now…
Vacuum and boost lines are done.
Still gotta run a line for the boost gauge but the T fitting is already in place. I’m hoping that I can reuse some of the transmission temperature gauge wires that are there so maybe it’s partially done (wishful thinking)
Street Lethal helped me out with a few EBL specific questions I had, like where do I wire the MAP sensor, repining and MAF delete….Thank You
This is way more work than most people are willing to tackle….
The only way I would have attempted it was with TGO!
Thank you to all that have helped me along the way…
Almost ready

Re: SBC SINGLE TURBO PROJECT
Try Accel shorty plugs, not cheap but. I have to pull the down pipe to install #5 every time and the shorty plug (a 526S for vortec heads) gives me some clearance. And yep, Rob/Street Lethal is the guy for sure, I'd still be choking in fumes in the dark ages without him...

PS just saw your pm now, glad you got the MAP sorted.

Re: SBC SINGLE TURBO PROJECT
OMG, didn’t realize that the EBL needed a NB o2 signal so I bought an OEM o2 sensor and welded in another bung. I thought that it would use the WB somehow….
Not to difficult at this point but it meant that I had to take the downpipe off again (won’t be the last time, I know…) and unwrap the fibreglass wrap, weld and re-wrap… ugh
With the exhaust out of the way I was able to finish the heater core/oil cooler lines and get the wire loom relocated up and on the fender so I could pull the MAF wires out.
I also took the opportunity to wrap the heater lines in foil to protect them from heat and figured I would do the same to the downpipe to protect me from fibreglass hair 😝 and the turbo blanket went on…

Re: SBC SINGLE TURBO PROJECT
I took a few minutes to post a YouTube video on my page “Sammy’s Garage”
The sound is bad, but I know why… (GoPro was in a sealed case….)
and I lost a bunch of wiring and battery box mounting video… 🤷♂️ Ugh
Over the last week or so I was able to delete my MAF and re-purpose a few of the wires for the MAP Sensor. I got a 5v power from the TPS Sensor.
So the MAP now has a vacuum/boost reference. The boost gauge needs to go in and a few pin relocations for the EBL ECU
Then taking care of the laptop and software before I can start it…

Re: SBC SINGLE TURBO PROJECT
Looks like I’m gonna need help with the EBL install.
I was gonna add the comm port to the smaller connector A1 but it’s already full. 🤷♂️
So I go check out what’s in A1 for a 1989 5.7L TPI ECU and it looks like it’s power for my fuel pump relay

Re: SBC SINGLE TURBO PROJECT
BIG Thanks to BobR from DynamicEFI
I have a much better understanding of what it takes to do a EBL conversion…
I thought it was just a few pins…(3) but I was wrong 🤣
I’ve just purchased a EF Connector
I’m gonna start labelling and removing pins from the connectors to reorganize them into their eventual locations.

Re: SBC SINGLE TURBO PROJECT
I really should sign in more often, sorry about that. I just come in and read posts, never think to check my pm's. Glad to hear you're taking a stab at the repinning. I also realized after reading the above you have a P4. I have the Flash 2, it seemed much easier to repin but it's the same process. Deep breath and one at a time. it'll work out great. Just wait till you get on the boost...

Re: SBC SINGLE TURBO PROJECT
OMG!!!!
After it was all said and done ….
It looks like the Ignition control module took a dump…
No spark…
Tested the coil it’s good
Need a new ICM
My luck….
Like brand new
Unbelievable

Re: SBC SINGLE TURBO PROJECT
that pic brings back memories. when i got my car, it had an ANCIENT Accel DFI (early 90s) in the factory location, and it used an adapter harness between the dfi and factory wiring harness, and that is where the wires would be switched around to the appropriate input. i had that thing out quite a few times changing pins around....

Re: SBC SINGLE TURBO PROJECT
K, I’ve got a faulty MAP sensor (was reading 12 lbs boost with the engine off 🤣(funny, not funny)
I’ve ordered a new one and spark plugs as well… the current plugs have to be super fouled by now…
back to the drawing board
