I am planning on fitting GTR injectors to my 32 GTST but am having trouble chasing up a ballast resistor. I have heard before of homemade devices being made, consisting simply of 6x10ohm resistors. Has anyone done this or does anyone have any information? Also at what power level do std RB20 injectors need replacing? I have heard stories mentioning anywhere from 170-250 rwkw. I do not want to do them unnecessarily at this stage. I am aiming for 200kw

All you need to do is buys 6 high quality ceramic 7-10 ohm resisters from farnell and solder them in series with the injector driver outputs on the ecu loom. I did this for both my brother r32 and my r32 and neither have had issues.

I soldered the resistors just past the ecu plug in the cabin. Works a treat. Farnell resistors they are alot smaller than the jaycar ceramic ones so installation is easer and neater.

I'll look up the part number tonight and post it then.

Not actually in any mad rush now. Was planning to fit injectors before next tune but due to overspending on other items its not going to happen now. Aiming for about 200rwkw & a lot of people seem to be making that on stock injectors pretty easily... Like to keep things on the safe side but so will definitely keep it in mind.

im making 191rwkw, and have only upped my fuel pressure from 38psi to 50psi. i have seen the option 1 garage drift car make 228rwkw on standard injectors

only?? that means at 16 psi, you are running 77psi of fuel pressure, hope you have a good pump

Ive done the resistor mod, they are smalll small resistors that you solder into the line just before the injector, been running it for a while now with a drift day included and havent had one problem, simply threw them onto the common wire (white with black stripe), roy does a DIY on this forum....

You may aswell upgrade to gtr items now if your planning big mods down the track

$25 delivered VS $170 2nd hand is a big improvement

    • 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.
