White32gtst

Been Chacing a issue for a couple weeks now, my rb20det starts and idles no problem, but hasn't been able to rev past 3k after doing a few upgrades, 1000cc Bosch injectors, arp headstuds, 25 box, e85 non flex, 2 stage boost controller, and a few small others. Anyways, ecu is cutting out at 3k rpm, all signs pointed to afm (had a ebay z32 on it) checked the signal wire to ecu, not sending enough volts, tried a stock rb20det and rb25s2 afm, both wouldnt let the car start at all. Bought a z32 for it and wired it up, turned ignition to on position, afm was sending correct volts to ecu, turned key on and it started and idled fine, checked signal, correct voltage. Just before I could see if it would rev past 3k, it cut out. Now my earthing situation is gone weird, afm is getting voltage, both signal and 12v power grounds will only ground with the ignition on first click, second click it looses the earth, signal wire is sending nothing to ecu. Tried wiring the old afm back up, which It use to start and idle fine with, and it won't run and having the same wiring issues. Anyone have any input? I've pulled out the ecu to open up to see if I've burned something, haven't had a chance yet tho. Any input appreciated, thanks

Yeah I got absolountly robbed, cost $160 and looked online and its $80 straight from Walbro

Yeah I'm not 100% sure if it would, but that's what I read on here not long ago. Did you need to rewire for 341? Maybe rewiring might be the way to go

Yeah stock pump feels like it's coming to its end. I've researched lots about that rewire but apparently you can have problems with fuel over heating and evaporating

does anyone know what the best fuel pump upgrade for a 1993 r32 gtst would be, running GTR injecotrs. Placed a Walbro gss342 in it a few weeks back and I would fail under load, guys at autobarn said most people run them in their 32s. Just wondering which one is best that I don't have to rewire and run constant 14v to it.

Replaced ignitor pack and had no difference, looking at splitfire Coilpacks now hopefully that fixes it. I read on forums about people changing the injectors to GTR and no one seemed to have this problem, so I'm hoping It isn't that. I'll still be taking it to a dyno once I've got it registered in about a week or two to get a tune.

No It wasn't running great when I first bought it about 4 months ago and I've slowing been fixing it up. I thought it was the previous injector seals and leaking injectors that's why I replaced all of it. It seems to misfire only around 3-5k revs, just wondering where I should start looking at what the problem is coming from? I've heard igniter pack might be a good place to start?

can someone help with an issue in having with my rb20det, it seems to be struggling to go through 3000 to 4000rpm seems to be when it tried to hit boost, and then goes past 4000rpm fine hitting to 12psi. I've recently installed 32gtr injectors and ran individual resistors not sure if that would be an issue? Also I've tried fiddling with the boost tee and it doesn't seem to do anything even if I take the control screw right out? Could it be wastewater or the tee? Any suggestions on where I should start?

Hey just wondering if you've got a LH guard? Front bumper? And rio bar for sale?
