ELO AGAIN. 3rd post in 10 minuts. LOL

Got another one, after installing my new pump WALBRO GSS342, i noticed that the car hangs at 1000rpm on the way down for a sec, and then drops down to 750 rpm.

I have only noticed this after the new pump. But it does not always do it, only sometimes.

It almost like when the fuel pump goes from full voltage to low voltage.

A simmilar thing happens when you blimp the throttel, as the fuel pumps kickins into high voltage, the car seams to flood a littel. I am going to direct wire my fuel pump so it is at constant voltage.

Has anyone have this, did a search but no good.

      Hi. Yeah thanks. Car is already at tuners and it staying there to resolve "many" issues they do not like. So it is in a good hands. Getting a good tune on that Nistune ECU too so the car would be good. Just needs a little tune up and love.

      Probably gonna remove manifold and turbo. I’m not sure if I can get M12 x 1.5 air tight. Could use high temp Loctite 246 or something similar, but I don’t know. Maybe it’s just best to remove everything again and weld an 1/8NPT on there instead.

      Yeah, saw the ratios, not impressed. Would like the punch I have in the first gears now. With those ratios it won't be the same.  Also want the h pattern gearing, or at least a quiet gear set that don't need to come apart for service each year. Looks like the only "reasonable" way Is a 8hp70 transmission, but where is the fun in that🤷‍♂️

      R34 4 door side skirt identification

      By nxh · Posted

      Hey mate, really appreciate the help. Have been looking pretty extensively myself and was certain they were retro fitted, but then ended up finding a 4 door with what looks like the same side skirts or at least the closest I’ve seen.

      Isn't there a PAR engineering gearset that has closer to stock ratios? And they claim they'll do whatever ratios you want.
