question...if you hate honda's/ or various other cars with variable valve timing why not just get a weinkl/rotary? try keeping the front springs stiffer then the back springs since it is a fwd car i personally like the car to be very responsive in weight shifting so try setting the spring rates to 13/12 and fidget around with the bound and rebound settings until you get what you want. and then use the camber,toe angles to get your desired speed around corners.
as previously stated the vtec basically gives you the low end power(tq) not really the high end. most race ready honda's that go up to 10k or over usually have a hollowed out camshaft and are labeled vtec killer camshafts due to it getting rid of vtec. but on production model cars vtec is helping you more then you can imagine. and if you find yourself falling behind due to lacking of top speed being an fwd just get some NOS and a large turbo you should keep up just fine.

i 2nd that opinion
VTEC is anything but what qksl2 wroteACTUALLY, he is on the right track.
VTEC allows extreme power output & smooth driveability on small displacement engines. Without VTEC, you'd have to use either one cam profile or the other, or a mix of the two.
There are aftermarket roller rockers available that effectively disable VTEC but locking the center rocker (the one the VTEC lobe rides on) to the outside ones. VTEC is always engaged. All that means is that it runs on the high profile all the time. The advantage in a race-only application is that it slightly reduces valvetrain weight when you get these rockers.
It is because of VTEC that a stock integra type R is able to make 80% of its peak torque at 2000 RPM.
I would be sure to buy the racing flywheel & clutch... high revving engines shift much faster in GT4 when those items are equipped.

lol i'm a moron? um alright yea some camshafts are made so it's there isn't vtec. b/c of vtec it opens up to allow more airflow but if you do this lets say at around 2000-3000rpm all your hp/tq is pretty much shot hence why you don't put your vtec controller down that far in real life. some of the info isn't exactly right b/c of me generalizing it so much. so yea i'm terribly sorry but what i am saying is true.
(btw i kept it civil and didn't start some e-thug fight lol)

http://www.leecao.com/honda/vtec/index.html (pretty picture )
there's a definition on how it works. in a pretty picture for you all to follow as you can see vtec is basically a system that opens and closes valves at different rpm's to either allow or restrict the amount of airflow into your engine. so on a high performance race only engines there is no "vtec". b/c there is no need to waste time on waiting for your engine to be switching to and from the low and hi lobes. since you want to only be on the high lobes. this is why as previously stated the integra type-r is able to achieve roughly 80% of it's tq at 2000 rpm.

NOTE: I UNDERSTAND THE VARIABLE VALVE TIMING MOTORS. I APPRECIATE THEM FOR WHAT THEY ARE WORTH, BUT HAVING TO USE A CAR AT 7, 8, 9 THOUSAND RPMS IS PRETTY ANNOYING!!!!!!!!!!!!! I DON'T CARE HOW GOOD IT IS. I KNOW IT IS A GREAT TOOL. I WAS JUST SAYING KEEPING YOUR CAR AT A REDICULOUSLY HIGH RPM CAN BE SOMEWHAT HAMPERING TO A LAP TIME ESPECIALLY AT THE TIGHTER CIRCUITS!!! ALL I NEEDED FROM YOU GUYS WAS A GOOD WAY TO TUNE THE CAR. INSTEAD, I RECIEVED THAT INFO FROM THE GUYS @ ISLAND MOTORSPORTS. THANKS FOR ALL YOUR INPUT THOUGH.

i needed i honda for the type R race. thanx for the tip about the rotary motors, but im not a fan of those either (no torque to speak of) now im not starting ****, but thats waht i think. please no one give me a diagram of how the wenkel works. i am very knowledgable (apparently i cant spell though) in the ways of internal combustion motors.
👍 Jonerz 👍

Oh?
Jonerz
Uh, if you say so...
Ha just givin' you a hard time... but no, if the car only had one cam profile, (the agressive one that gives it the top end), without the variable valve timing, lift, & duration, it would be undrivable at low RPM - not just bad fuel economy, but no power.
As far as your original question - the only way to significantly increase its midrange punch is via forced induction. Get a stage 1 turbo - it'll spool quick, and give you some balls in the middle of the RPM band.

just get nos, and use it you whoop up most of the competition on high end get a ton of a-spec points rather then spending a ton of money and losing a-spec points by doing NA or adding a turbo. to each his own. lol sorry i was just stating why vtec was good an bad but was then deemed an idiot. as for dialing try these settings out i haven't tried them up yet but theorhetically they may help
SR 13/12
bound 9/7
rebound 5/5
cambers 2.5/.5
toe 0/1
stabilizers 5/5
tcs at 4 or 5 pending on HP
and tranny set to which ever track you're currently racing.
hope this helps to your initial post.
also the racing chip is supposed to raise the rev limiter, make the fuel maps more aggressive. and usually typically lowers the rpm point in which all the intake valves open.

i haven't play gt4 in a long tme and i jsut had it for like 4 weeks but yeah i'm only like 9.11% done but i can tell you about vtec engines because my cousin jsut put in a japan verson vtec in his civic and the diff between the vtec in amerca or canada is that the japnese vtec give out about 170 hp and the ameracian verson give out about 140 hp so if you put in an new intake and change the headers you should ride smooth
oh and add twin cams or racing cams stage 3
