chances are you are running lean at the moment. there is no need for a set of gtr injectors till you are running 190 rwkw. but at 160rwkw your standard fuel pump is struggling and should be replaced.

if you are not going to run anymore boost than what you are already running then you will get little or no performance gain from injectors.

but you should get a fuel pump for safety.

I have the same mods (NO FMIC though) and my car makes 165rwkw @ 0.7Bar.

Yet i have a fuel pump and also a chipped ECU.

My suggestion would be to get the fuel pump also as they help more than most think.

I'd say you'd be looking at 180 -190 rwkw with a tune and pump. My chip gave me 11rwkw!!!

how much power can u get from a high flowed turbo on an Rb20 then?? i wanna get to around 240rwkw....what would i have to do to get me there without replacing the turbo again... i thought if you got adjuctable cam gears and a fuel system upgrade you can reach this goal pretty easy

I have a GTR fuel pump in an R32 GTST, it sorta bolts straight in. It is bigger in diameter so you have to modify the rubber bottom mount, plus I fitted a stainless screw clamp around it and the bracket just to be sure. :rofl:

Cheers for that SK! Sound easier than fitting an aftermarket job.

I assume the 32 & 33 GTR pumps would externally identical. For $100-$150 would it be a worth while upgrade for someone chasing less than 180rwkw?

    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always! 
    • Yeah mate, never miss it.
    • Any going to watch World Time Attack at SMSP this year?
    • Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
