small update, I have the exhaust on and the undersealing finished but i'm still working on the problem with the revs not building,if anyone has an stock ecu for an english spec s14 id be interested in it
So i've tried three different MAF's and a different ECU in the silvia and there doesn't seem to be any difference the engine revs to about 5000 and wont go any higher,i was wondering would in be an earthing problem as i have a small black wire with a small black box on it left over from when i swapped engines
if anyone has any suggestions as to what could be wrong i'd really appreciate it
without having had a look through all of this...youve changed the fuel pump right?
In the process of putting a walbro into it now but I didn't think that would make a difference?
