So ma m8 has just built ma cvh turbo there with new acl shells and re ground crank ..i had had some very low miles pistons and rings so just used them..he used the inlet wich was on the zvh that was removed .. He took out the beige injectors and put blues bk in and removed chip just to run it in but when he starts it up its just constant revving up to 4000 and thats not good for a new built engine ? just fishing for some ideas He done the usual checks..air leaks etc..unplugging tps and idle valve but no joy

anybody any ideas ???

Air leak on the inlet somewhere?

id say same as studabear... does the car run when you unplug the idle control valve or cut out? if it runs its an air leak... my car done it a while back a pipe had come off the throttle body

Yeah still runs when disco icv ..prob is leaving it reving the tits off its sell to find the prob.....

definatly air leak on the inlet somewhere... just check pipes for splits or to see if ones popped off i know on the rs2000 engine its somtimes down to the o rings on the injector rail
