Got my r33 gtr tuned yesterday and was suprised at how much power i made....

stock rb26 motor with r34 n1's etc.....i made 314awkw with 85% injector duty cycle...i fitted cam gears but they werent tuned at all.....now im thinking i wasted time buying them....

mods:

044 pump

exhaust and dumps

555cc inj

arc panel and box filter

r34 n1s

stock internal motor

bleed valve for boost

in and ex cams

apexi powerfc and h/c

I was told to get an ebc next time to hold the boost better, and also get bigger injectors for more power.

What do you guys reckon?

ps boost comes on the same time as the factory ecu did, and that was better than with stock turbos i had prior so im happy there....

What boost is at peak power? that being you said boost tails off hence get an ebc to hold boost better. ;)

Hey i dont mean to change the topic too much but does the apexi avc-r have the same feature to stop the boost dropping off at high rpm? I know the e-boost 2 has a RPM Compensation Feature but i wasnt sure if it's common amongst other electronic boost controllers.

I personally don't like the eboost. They always seem to break.

The avcr is the most customizable boost controller of which when tuned by a novice performs poorly which is why some state its crap. Get the avcr on a dyno with some one who knows them and they are an awesome boost controller with a massive range of features.

BUT.. the Greedy Profec B ebc is a great cheap ebc. if boost is tailing off you can dial it in so that it holds boost at higher rpm. if its creeping you can attempt to dial it out. But usually if it creeps (boost goes up with rpm) usually its a mechanical problem (poorly designed dump or wastegate)

      I used "different strokes for different folks" quite pointedly as honestly, there is no wrong when it comes to choosing what you like.  I always day dreamed about flappy paddles with fast shifts in a sporty RWD Turbo and to me the sound and feel of it cutting through gears in a steady stream is exciting, engaging, and keeps the car better balanced - I *also* like h-patterns, but I find them more engaging and fun in a nice hoonable peaky NA thing.  Type-R Integra/old school NA rotary, things that are raw and need all the rpm where picking the gear and getting it sky high is part of the engagement of the whole thing despite the fact that they probably need closer ratios and faster shifts even more than a 3l turbo thing haha

      If I wasn't allowed or really had the desire to visit China it would probably fit in my carry on, but I have no desire, Japan would be nice during Cherry Blossom time though I might need to chat to Jackie about that, that should actually be an easy conversation though as she is currently talking about another cruise, cruise ship to Japan, a week in Japan to see the sights, then cruise home I may even be able to find those OEM NC Recaro seats over there that I cannot find here 馃

      What do you mean?  In between the two I shared?  They're the same boost   This will be insane.   A mate has a GTSt with a 9:1 RB30/25 with Tomei 256 cams and a Borg S362SX-E that is already a beast from the basement but has a stock 5 speed and will probably get a ZF8 one day.  After the G35 900 RB26 setup I'd be lying if the topic of "Wtf would a divided G35 be like on this thing?" idea hadn't come up - you'd definitely want a wide boost control range setup with it, as even with the less responsive and potent S361 we're having to ramp boost in from very low levels in the early gears.

      ZF8 is faster, wider ratio spread, better in every way. I do not dispute this. But I have brain damage and I want the feeling of shifting gears. To me the extra work is fun, but I daily an automatic and in the US like 90+% of cars are automatic so a manual transmission is an "exotic" experience. If I want an automatic I've driven an F80 M3 with DCT more than a few times and it's incredibly capable but it's emotionally vacant to me.
