New guy to the GN world and had a quick question. Bought an 87 GN with 5051mi, high option slicktop car, GNX rep wheels, car has been sitting for 10 years, climate controlled but hasn’t been started. As such, I’m in for full fuel system, fluids, maybe gaskets/hoses. I want to bump up a few things while I’m in it, but conservatively and had a few questions.
Currently the car has:
-Stock turbo, but previous owner states the “hot side was ported,” otherwise stock motor
-38# Blue Tops
-Unknown cone style intake
-Accufab fuel pressure regulator
-MSD plug wires
-Unknown chip
-Unknown intercooler modification (looks stock but prior owner remembers having done something)
So far I have ordered:
-GN1 3” Dual Exhaust
-GN1 3” Downpipe (internal wastegate)
-GN1 3” Cutout
Here’s where I need some guidance:
-Want to bump to a Turbo Tweak 60lb injector and chip combo. Is 60 overkill and can he tune for my current setup, maybe ~17psi?
-I’ll be replacing the fuel tank, and Holley makes a complete EFI kit with a 350lph pump. Seems like good insurance but will it work with current setup or overkill and should just go with a smaller in tank?
-Should I replace the fuel pressure regulator considering I’m doing the full fuel system, and is there a preferred brand (accufab, racetronix, etc)?
-AC Delco R42 or R43 plugs?
-Gaskets needed if nothing is leaking?
-Going to flush and refill ALL fluids. Planning full synthetic for all, unless you recommend otherwise.
-Toyo R888R 255/50r16s seem to be all that fit
-Do I need a Scanmaster?
-Do I need one of those turbo saver oil feed kits?
-Anything else considered a must do at this point?
I know that’s a lot, I appreciate any and all advice, I’m reading a ton but it’s a little tough to sort it all at once. Just want to get her running smoothly, making a little power, I’d be happy to crack a 12.9 at this point. Down the road, may bump up to a TA49 and more like 20psi but not this year.
Thank you all!
