I believe it's closer to 6500, check your ECU maybe you have a D15B8 ECU (P05) running your engine.

Jimster480

It should be around 6500, as its powerband doesnt even peak until 5900.

i have a virgin p28 in it! was gonna go mini-me.but im pretty sure itll stop at about 5500. ill ty and upload a video of it today. could it be off if my speedometer is wacko?

talonboy1991

are you throwing a cel with the p28? the ecu you need for a b7 is p06, youre redline on a p28 should be like 7500

ej1619

yeah it its throwing a cel. cause its for vtec right? if i were to put on a vtec head it would go away?? and ill up load a video

talonboy1991

its throwing the code for the vtec sensor and yes you could do a z6 head swap but its alot more than just slapping it on you would need to get a new timing belt and replace all gaskets you encounter pulling the old head off and you would also have to have your ecu chipped and tuned (something few people do on mini me builds) because the d15 pistons create higher compression than the z6... the easier route would be to just put a p06 ecu back in or get the p28 chipped to a p06

Jimster480

your probably hitting the cut becuase its a p28 and you dont have VTEC. I know some Virgin ECU's dont let you rev past the VTEC engagement point typically if VTEC doesnt engage. Because my friends CL had a issue with the solenoid and his would hit a "rev limiter" at about 5400 or so because of the VTEC.

ej1619

i dont think the ecu has to do with it cause i had a p06 in it befor the p28 and it was the same way? video on youtube -is my rev limit normal

Jimster480

Well there is really no reason for it to hit it there unless your tach is just off by alot. What does it read @ idle?

ej1619

at idle its fine around 1000

Jimster480

you should idle from 700-800

ej1619

jus went out and checked. you were correct, right about 800

Jimster480

well then your tach isnt off, so it is for sure hitting the limiter at the wrong RPM. Especiallly if you put it on a P28 and it doesnt hit the non-vtec cut, it should go to 7200RPM because thats the redline on a Z6.

ej1619

Yeah that's what I'm sayin! So any ideas on what to do or what the problem could be?

JDMxTai

Uhh... could be dizzy or tps.

I have never heard of a stock rev limiter being 5600 maybe the car has an issue and the previous owner had a chip installed with that limiter set.

JDMxTai

It's a virgin p28........
It cuts off at vtec so its problem with vtec

ej1619

but it did the same thing befor the p28

ej1619

nothin? anyone?
