Hi guys, this is my first post in this forum and i hope that u guys can help me.

Im BOB..and i would like to ask some question to u guys.

Rb20 are using top feed,high impendence, 270cc injectors

4G93 are using top feed, low impendence, 450cc injectors.

RB26 are using top feed, low impendence, 440cc injectors.

am i right??

Did some research, most of the RB20 owners fit in the RB26 injectors with resistor pack.

But, I found some article in other forums mentioning about fitting in a 4G93 turbo injector in an RB20.

My question is, can i use the GTR resistor pack with the 4G93 injectors??Or i have to use the 4G93 resistor pack??

I hope everyone in this forum could help me...........

Thank you in advance........

Standard rb26 yellow top 444cc injectors are 2.0 omega resistance. Yellow top 4g63 injectors are 2.9 omega resistance.

So I probably wouldn't use a standard GTR resistor pack, although you would probably find it would work OK. Best thing to do is go down to dick smith and purchase the correct individual resistors and wire them inline just above the plugs on the live 12v side. If you take those figures down to dick smith they can even look up the resistor colour coding for you and let you know which ones to purchase.

That will cost you about max $4 plus its more accurate. A resistor pack will cost you atleast $150 from a GTR.

    • My hold point for future mods is that I want a OEM detachable hard top first, but, finding one is a pain, MX5 Mania are looking for one for me, but, as hens teeth are more common, finding one in Australia is proving problematic  I can get a OEM one from overseas, hell, you can still get new ones in 'Merica, but, shipping is a absolute killer and I cannot justify the cost, or the risk of it being damaged during transport As for the aftermarket hardtops, whilst they do the job of being a hard top, and are fine for a track car, they don't seal well (read: leak like a sieve in the rain), and you need a plastic/poly rear window, plus they are a bolt in option only and not made to be easily removed I liked how the hard top on my NB could be fitted, and removed, by myself, in less than 5 minutes I know it sounds bad, but I'm waiting for someone to write off a car with one so I can swoop in on their pain, it will go to a good home though, so my guilt of this is tempered
    • I’ve got one on mine and it’s fine, 
    • No, you don't want to plug the vacuum line, as that will turn that side of the booster into an air spring and probably make it feel worse. I'm not saying that the GTR master itself doesn't need a booster. I haven't paid attention to the GTR one to know what size it is cf the non-GTR ones. But when you think about it - they have to do the same job, which is to move a little slave piston a few mm to do what it is supposed to do, and that final action is the same on all the cars. So, it is very unlikely that the GTR MC is any different than the others, because it has the same pedal stroke and the same output requirement. The booster just makes it feel easier. I'd suggest you probably have an actual hydraulic problem. It's totally common on these old shitboxes.
