yet another turbo vg
#3
i think its someone we know on the org, just not sure who. i've seen somebody just paint the interior of the engine bay that color while keeping the rest of the car a different color. im guessing the outside of the car isn't blue?

Probably cause you can manually adjust the timing, unlike the VE

I have the Z31 manifolds but opted to make my own 1 7/8's stainless steel manifolds.The heads have been ported and polished. It's got Ferrea 1mm oversize stainless steel valves,370cc injectors, Z32 MAF, JWT S2 cams, JWT springs, and JWT ECU. The turbo is a GT30r dual ball bearing turbo.

Wouldnt those still just be exhaust manifolds? I thought with headers all of the pipes are the same length as to create an equal pulling force. So if i was told right with my theory then those wouldnt be headers correct?

manifolds are generally cast iron. those would be considered headers. they make equal length headers and they make non equal lengths...but still they both are headers.

do you have an auto or 5spd trans and who beefed it up what did they do

Those pics are all from when the car was getting worked on. The y-pipe doesn't hit the x-member when the engine torques. I also had the x-member reinforced b/c i've seen a few people on the org that have broken them N/A. I don't have #'s yet, i'm working out a few kinks in the system. When it's cool it hauls a**, but when it warms up, it doesn't run as well. I've changed out the TPS, Knock sensor, tried a different MAF, but i still can't figure out the stumbling at high RPM when it's warm. I might have to do an MSD Ignition setup. On cool runs i've run from 8.5 up to 17.5lbs of boost without any signs of detonation. At 15-17.5lbs, even from a roll, it's still lights up the tires. I'm really testing the limits of this so-called "Beefed up tranny." Hopefully i'll have everything worked out within the next couple of months, so i could post some #'s. It sux not having a day off since new years, lol.

Subs, I had the transmission rebuilt twice(it messed up a year after the first rebuild), so the second time i spent extra money for a higher stall Torque converter(2800 stall), valve body job, and a few other things, hopefully it will hold up(I really doubt it, but we'll see). If not, i'm going manual.

are these so called air/fuel gauges running off narrowband (non fivewire) sensors because if so there idea of rich could still be very lean since a narrowband sensor only reads down to 14:1 A/F which is still very lean since a turbo car need to be low 12s if not 11s
heres a graph of a narrow band sensors output which explains it all
as you can see a narowband sensor does not know the difference between 10:1 A/F (to rich) and 14:1 A/F (to lean)
so with narrowband sensors your pretty much running blind (there useless) except when tunning for best gas mileage

Thanks for the the advice, hopefully i'll get this figured out soon.
