i jus installed an fmic and a boost controller, my car i an r32 gtst, with rb20det, standard injectors and pump, done 89,000 km's and the engine has been perfect for me besides having to change my fuel filter, but something strange is happening now since i put in my boost controller, was running fine on 12psi before it put it in, and with only and extra 1/2 psi it startes to wind slowly, then it clicks and then the power punches in, some times it feels like its not getting enough fuel too, jus wandering whether my pump cant handle the power or if its just out of tune, i plan on puttin in a walkbro pump asap, any other idea's?

What sort of boost controller?

Drop the boost back to 12psi and see if the car runs as it used to. If not then try removing the controller temporarily and see if it runs properly.

Just a couple of ideas before you spend the cash on a dyno run.

Is it spiking? It could be spiking causing a lean condition, resulting in the flat then kick feeling.

Thats if I've interpereted your post correctly.

EDIT: I still suspect the std pump is on its last legs. Being 10+yrs old and all.

At around 80,000km's my std pump was right on the limit at 12psi.

If you can find a cheap $35 power run then do it.. I wouldn't be spending $80 on a simple 1 minute power run. :)

That $80 can be better spent on a new pump, as after all... if you are like the majority, we all get the bug, end up dialing more boost, ecu, injectors turbo.. Money permitting of coarse.

I've managed almost 10k worth of mods in the last 2.5years while I've been studying full time at Uni. :P

6k was spent silly as I didn't 'really' need the rb30det as the rb20det was perfectly fine. lol

      While doing my tailgate struts I found some rust. Also replaced my bonnet struts. Such a cool satisfaction with that job.

      Should I use rust converter on this?

      By PranK · Posted

      So I removed as much as I could from both sides. The shop vac did a great job of clearing 99% of it. I got it all as clean as I could and then absolutely drenched the whole lot in the rust converter. Tonight or tomorrow I'll hammer it again. The cavity must be close to 400mm in length and surprisingly I was able to get it right to the back.  I'll quickly reassemble and then pretend I never saw it. I'll post pics (for me to ignore later) soon.

      Help Understand GTT Boost Setup

      By GTSBoy · Posted

      I have always resisted the urge to go silly. 8" wide wheels and street friendly spring rates? Check. (Let's not talk about the steadily increasing spread of spherical joints across my suspension!!) Stock turbo, run at 12 psi? Check. Lasted for~?10 years before it died. Highflow put on rather than seizing the opportunity to go G45. You don't need 300 rwkW, let alone the more massive numbers that seem to be essential these days, to have a car that is already way too powerful and fast for a streeter. ~250rwkW is fine. I've never exceeded 200, although I will sneak up above it if and when I manage to get my finger out and do what needs to be done to use the highflow's capacity. You don't need $10k worth of CF bits glued onto the outside. You don't need razor sharp ankle cutting front splitters. You don't need the car to be 2" off the ground. You don't need flawless paint, mirror finished wheels, brand new indicator lenses, etc etc. All these things just make the car impractical and will cause you pain when they get damaged, which is inevitable for a street car. A few nice additions are good. Good seats are good. A nice stereo is good. A/C is good! (46° on the road yesterday and my A/C is degassed again. Was moderately traumatic driving home!) The main reason I stick with a mildly modified old Skyline is that I have had it for >25 years, the mods are the rolling result of 25 years of things dying and being upgraded opportunistically, coupled with a few "just 'coz" ones. And I hate almost all modern cars. If I was a young buck starting out now.... I wouldn't bother. Cars have a few years left where there is any possibility of interest or fun. Thereafter there will be no such thing allowed or possible. Any time, money and effort spent now on a project would just be a waste.
