i own a R33 S1 GTST ..

boost is only staying at 4psi on the standard boost gauge in the dash..

i am installing an aftermarket boost gauge in tomorow, but just wondering because i have read elsewhere in the forums that after certain rpm ranges, it goes up to 7psi...

how comes my constantly stays at 4psi...?

can anyone clear this up for me?

thanks...i am going to try the boost soleniod DIY tomorow also, will this help?

maybe right now it's not grounded right?

anyone noticed the same problem before? just thought i bring it up in case there is a problem which can be fixed or something i should watch out for..

thanks in advance..

Tommy

    • Hi All, I'm based in Sydney and want to get hold of 4 stock R34 GTT wheel caps as pictured. Cheers
    • 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..
    • 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.
    • 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. 
    • Ah yep. I asked a auto electrician about getting a cheap rebuilt alternator vs a new one. He also said he used to it back in the day but it ended up costing similar to what a new one would and recommended getting a new one,.
