well the other day i met up with some buddys for a cruise around town, it was basicly a 240 mini meet with my FC tii and my friends 20 Valve 86 as filler, all the 240's had a sr20, or a rb26 with blah blah blah, anyways they were fast, i basiclly burned 2/3 of my full tank in bout a hour, need less to say i was mashing the fun peddle for quite a while... and i noticed that when it hit 6000 rpm there was a slight hesitation, i know that this problem was in the 3rd gen but i never heard of it in a 2nd gen?

i did a search, didnt find much can anybody help me out?

 

well, 3000 rpm hesitation is pretty common, and the cause of that is usually bad grounding, so you could check that out i guess.

 

well when i did my tune up and block off plates done the 3800 hesitation went away, now its 6000 rpm... whats going on?

 

I've got the same but on an NA. I think my problem is exhaust restriction.

 

Clogged fuel filter or air filter maybe. Maybe your injectors are getting maxed out or something. Have they been cleaned recently?

 

You're running full exhaust with no FCD???


-Ted

 

replaced fuel filter last last time i changed the oil, just finished the TID so its a new air filter, i just put in injector cleaner when i filled up!... ????

 

yes i am

 

I also have the same problem but on a n/a like imischeifin. Its very quick though it dosent lag as long as it did when I had the 3000 one. I have basicly the same mods as you apexdrift except I have msd,msd wires, K&N cone, and some mapping changes. Do you have your air pump, acv, ect.....? o yea you have a turbo nevermind.

 

Hmm - Intake & exhaust mods - with no fuel mods, boost gauge, ported waste gate?

Hesitation? - maybe boost creep & lean out..

Sounds kinda like the same dumb thing I did.
Lots of fun, but really hard on the motor.

A rebuild or J-spec is in your near future.

 

its not ported, and no fuel mods, but yeah i got the boost guage and i jsut noticed last night that im boosting 10PSI so would this be bOOst creep?...

i never cosidered it until last night! OMG what do i do?...

 

ok the more i think bout it, its not boost creep, because my boost guage stays at 10... cold the problem be jsut leaning out?...

 

um yeah. I'm an NA guy and I know that. check out the archives. get a walbro 255, get 660 or 7~something CC secondaries, port your wastegate, and a tough clutch are all in order.

 

oh and I could do all of that in one day 'cause I'm bad and all. oh and I have to same damn problem with my NA only its at 5,000rpm. my injectors are all junkyard pieces so I am gonna have em cleaned. none of my garage cleaning methods have worked so I have sent some off to cruzin.

 

I was going to say VDI~5800rpm, but then realised it was a turbo...

 

I sprayed mine with brake fluid cleaner, probably didn't do much. Oh well, at like $2 a can I'm not losing much.

 

keep this up and you're gonna need a rebuild soon.

running full exhaust and intake, your secondaries will max out and you're going to lean out your engine. spitting fire?? thats a good indication. be smart and do some fuel mods.

 

no fire spitting....(yet)

so what fuel mods would be in order?

 

hello?!~
anyone?

 

look earlier on the thread dude..... something involving a pump and secondary injectors...

 

my car is doing the same thing i think just after 6000 RPM's, in first and second theres slight hesitation, when i shift it sits me back and its only some of the time. some of the time its fine and i shift at the buzzer. I have no mods but a racing beat cat-back, whats wrong???
