i really love my r33,

its fast good response, but it just seems to be crap in the top end around 5000rpm... just flatens out, i think the power curve would look like this

_

thats what it feels like, even on 14psi, i hit max boost quickly and it just stops pulling, compared with my old cordia whitch seemed to have a long lasting pull all the way to redline,

is this a normal thing?

also i installed an air/fuel meter (tomei) and its saying @ idle upwards of 16:1 afr on boost it drops to 14:1 and wont go down from there... then off boost climbs back up, i reset my ecu and it stayed in 14.1:1 - 15.5:1 afr. but slowly its climbing back up.. im gonna dyno it to see if its right... what can be the causes????

15:1 afm while driving on boost??

Mate your engine will be ***ed if it isent already running that lean.

And you are running 14psi through the stock cooler and you live in NT??? r u crazy?? the intake air temp much be sky high and apart of what is causing your lean out. Jap cars aint designed to run in such hot conditions like in NT. Get yourself a big fmic or drop the boost down to about 10psi max in that heat and get it checked out or you are gonna have a blown engine very soon.

    • This is a recipe for disaster* Note: Disaster is relative. The thing that often gets lost in threads like this is what is considered acceptable poke and compromise between what one person considers 'good' looks and what someone else does. The quoted specs would sit absurdly outside the guards with the spacers mentioned and need  REALLY thin tyres and a LOT of camber AND rolling the guards to fit. Some people love this. Some people consider this a ruined car. One thing is for certain though, rolling the guards is pretty much mandatory for any 'good' fitment (of either variety). It is often the difference between any fitment remotely close to the guards. "Not to mention the rears were like a mm from hitting the coilovers." I have a question though - This spec is VERY close to what I was planning to buy relative to the inboard suspension - I have an offset measuring tool on the way to confirm it. When you say "like a mm" do you mean literally 1mm? Or 2mm? Cause that's enough clearance for me in the rear :p I actually found the more limiting factor ISNT the coilover but the actual suspension arms. Did you take a look at how close those were?
    • @GTSBoy yeah sorry i know thery are known for colors bud those DBA are too in colors 🙂 Green will be good enough for me  
    • That's my life. Past-Duncan has a lot to answer for
