wat is wrong here

[214kka-et240sx]

ok i have a ka-et set up and it runs good but for some reason it stops pulling and high RPM like btw 4500 and 6000 when i run on freeway but it has good tuorqe so is it my engine or is it my turbo cuz the first time i ran my car when i finished the set up i ran a STI WRX and i kept up with it and now it it beats me by a little bit maybe by half a car so is it me or is it how my car is or could it be how my SAFC is set up help me out

p.s i am running on a t25(z32 turbo) so is it turbo or fuel that it needs

How many lbs you running.Checked your compression? Maybe fuel injectors are clogged a little maybe you got a leak in a vaccum line somewhere.Multiple possibilities.As for the race.Either your clutch could be slipping.You've lost skill shifting or your friend has gained skill at shifting.

i think its your turbo because that size of a turbo shouldnt be making much power at that high of a rpm. slap on a bigger turbo and see

[214kka-et240sx]

will it's not really skills of drive it's just goin striagt so i think yea it's turbo

[Florida240sx]

Well as long as you are accelerating wheter straigh or turning I would hope that you shift so maybe shifting skill has been improved.That's why I beat my friend's 240 who has mods and I'm stock with a 300lb sound sytem.

Mine dose that too in that RPM range your gonna need cams to get a torque feel up there I think its just the stock cam grind / not liking to rev up / longer rods but thats just my guess.

A Z32 turbo is extremly undersized...does your boost drop off in the higher rpms? Those turbos'a aren't much good in the form of twins on a 3.0, so 1 is just two small for a 2.4.

Holy Grammar and Spelling BATMAN!

That turbo is too small, and that STi is slow.
