ah right right, do gtr injectors fit in the std rb25 fuel setup and would i need an ecu if i upgrade them? i know that with the rb30's its u haveto change the ecu if u have the injectors. But im not too sure on the rb25 ecu.

According to HPI stock r33 injectors are only 370cc/min and as such run out of flow at around 200rwkw.

really???

i have about 200rwkw with standard injectors and the are nowhere near their max duty cycle...

i think they are only at around 70%...i thought 250rwkw was achievable with standard injectors??

also dont believe everything you read in magazines, rather talk to people with experience...

aren't SR20 injectors side feed as well?

Yes, SR20 injectors are also side feed. You will need to buy larger Sard/Nismo/Bosch/Denso injectors if you want an upgrade as there is really no standard injectors that are an easy side feed upgrade.

I thought I read S15 injectors (side-feed) were a straight fit on R33 GTST? They aren't 550cc but they are higher than r33 std 370cc, maybe 470?

Also GTI-R SR20 injectors are top-feed and some side-feed SR20 injectors are only 370cc so same as R33, so if you go sr20 make sure you get the right ones.

Well how much power are you chasing?

If Jetdat is right then you can get 250rwkw with std injectors.

The most i can get in standard from, standard being ecu, bottem end, cams. Maybe around 200 - 250 rwkw. Ultimately in the long run around 300 350 rwkw using a 35/40 and maybe rb30 bottem end rebuilt with steel rods and forged pistons and a good set of cams.

      Exhaust silencers/varex exhausts

      Curious to why you're not getting Jesse to do the exhaust, seeing that he has just done 2 GTRs with Aes valves.

      What extra parts are you thinking you'll need to run e85 compared to e30?

      I'm not aware of e30 in Australia, but I'm pretty sure e85 is still around. You really want a setup with an ethanol sensor so you can run any mix of ethanol depending on what you can access. Fuel Check NSW app shows 14 site in sydney metro with e85. What are you adding, will you put in bigger turbs too? Apparently the wastegates are pretty small and can't bypass enough as you run more boost.  I'm sticking to 1.3 bar with 98 on the standard turbos with my tune on advice from the tuner, and boost drops significantly in the top end; apparently larger turbos with larger wastegates are needed to get anywhere meaningful from there.

      Finding E-30 & E-85 in Sydney

      Hey Ppl,   I am about to tuned my Infiniti Q60 with E-85 and if you can tell me some location where I can top up my car that would be great.   But my other question, is E-30 available because this tuned requires less mods parts and any info you can offer would be greatly appreciated too!!
