Now i know this is possible, but not too many celica's i've spoken to have gone through a full engine balancing, making the red line kick in about 9 ish and lift engaging the whole time (maybe flash the ecu to remove limiter)...does this sound at all possible?
i think its possible for the 2zzge to be balanced and made to spin 9k rpm,but a lot of shit has to be changed,like valves.springs,oil pump(stock oil pump is said to be weak and break under preasure),oil cooler(at hi rpm oil will foam)need head work(Intake
and exhaust ports as well,to help flow the massive amt of hi velocity air at 9k)the 4 age,the motor that the 2zzge is supposed to be replacing can spin 9k with little work so i cant see why the 2zz should not be able to do so!i dont think the stock ecu can provide the fuel and timing etc. for that hi an rpm though!might have to go stand alone.
btw.i have a gen 6 accel dfi racing series fuel management system for sale(used it on a celica with gnx motor)mint!
