Ok so i installed it today and started the car.... Runs relatively smooth for maybe a second then puts/coughs and dies unless i get on the gas. Pressure tested from the end of the rail (t piece off adapter in end of fuel rail) and got a reading of 30psi. Adjusted the reg up and down and could not find a sweet spot where it will idle at all.

The reg had been used only for testing on a mates gtr. Only for half an hour. Is it possible it was damaged?

Anyway im changing the fuel pump tommorrow to a walbro and see what happens.

Is there any common mistakes of people dikn these up?

Cheers guys

Nah, theres some issue it seems with the ecu. On ignition the fuel pump ir running at 12 volts, builds and holds fuel pressure then after a min voltage drops to around 5.5v. A mate tells me suby's have this issue and they earth the fuel pump to the body thuss running 12 v continuose flow. We shall see as this does not seem common on r34's

      Need AC Compressor for R32

      Haha im flattered! Although my poor boat is collecting dust in the garage, as it hasn’t been driven in like 6 months. I forgot the to put the trickle charger on too, so the battery is likely toast now.. I have the frenchys kit. It is fantastic. My only gripe was that the hard lines from the firewall needed some tweaking, however, this was mainly due to my specific turbo and dump combo. The weight and size packaging is much nicer too. I think I have some pics on my build thread somewhere.. my justification for the kit was more “why not” I had gone to the trouble to modernise just about every other part of the car..

      Does 98ron contain ethanol?

      By GTSBoy · Posted

      Actually, ethanol has probably never been cheaper, on a tax free basis, than petrol. With fuel excise being what it is, and only being levied on the hydocarbon component, not the ethanol component, and ethanol for non-drinking purposes not being subject to liquor excise - E85 was cheaper, but not because the combustible liquid itself was particularly cheaper.

      Will I Need A Retune After Cahanging My Catalytic Converter ?

      By Murray_Calavera · Posted

      Maybe? If changing the cat to a higher flowing cat, caused the turbo to spool more quickly, and those areas of the map had not been tuned for the boost level it is now seeing, then yes you would need a re-tune. How dangerous it is running without the updated tune would depend on how far out the tune is with the now higher boost levels, how the engine protection has been setup, is the ECU compensating with a wideband sensor, is the boost control closed loop blah blah million other things... But yeah having said that, I wouldn't be surprised if changing out the cat for a high flow, in say a full 3" exhaust, made no noticeable difference at all.
