86 GT LSX Turbo Main Build Thread

[BlueCoupeRedVert]

Have not done much testing.. No fuel smell from open headers.. No spark from pulled plug touching block.. Will check voltage later and jeremy is bringing a node light over.

[KBScobravert]

Are you getting constant 12v at the injectors?

Where does it come from?

Does it fire a node light?

How do know you aren't getting injectors to fire?

Everything is done... But no start. Have fuel pressure..but injectors are not firing and no spark... Pretty sure computer is coming on.. Bluetooth odb2 port reader is getting an ecu signal and some sensor readings... Hoping noe at this point, James can save the day.,lol

Keep updating your thread. I'd like to see what you end up with.
I'm probably looking at another $3k in turbo stuff.

Will do. Hopefully tomorrow Ill start getting the 302 that's going in shortly undressed and cleaned. Changing cams, rockers, springs, etc. Id like to have it in by the end of the month, and I think I've got most everything I need to do that.

goin for 5.8ohs?

I'll be lucky if it spins the tires lol

The internet builders are quick to throw out the $3-500 pick & pull 4.8\5.3 LS motor, trans, harness stuff. No one seems to remember that it doesn't fit the chassis, electrical, fuel, cooling, or a\c system at that point. It's a real eye opener when you actually start putting a car together and open a parts catalog or start ordering parts online. $ adds up in a real hurry. Congrats on making some progress and sticking with it.

Maybe i should give him an invoice for my time and labor..lol
Hoping it will be ready to start this Sunday evening

The ecm side of the neutral safety runs through the MLPS (range sensor) on the side of the transmission and the trans harness wiring. As far as going from the ignition switch to the starter, you could bypass it, but it's a nice safety feature and would take minimal wiring to have it functioning in my opinion

Yeah, I could plug it up easy with the stock harness. My ignition to starter is independent of the ls harness so that isn't an issue. Just don't really want to spend the $50 (on the module) if I don't need to.

I'll get with you very soon - need vats gone.

Do you have to run a neutral safety switch on a 4l60e or can you tune out?

it definitely adds up fast. i took my running/driving/racing ls-coupe and decided i wanted to do some "upgrades", i don't even want to add up everything, but i think i blew my budget about 4 hours into the deal.
