change your engine AND dont waste your time

or u enjoy conrod shooting out from your block?

so much effort on it..and stock 92 mivec or 93 dohc will still pass u like u never existed..not need to say gsr

the risk of getting conrod flying out...plus higher fc than gsr when using afc to tune fuel..

1 week = 3days car in workshop, 3days on the road, 1day being towed

all this happen to my fren who bolt on his 93 na

if not for the performance why u want bolt on? for saving the earth?

oh ya..not yet finish..enjoy the tok-tok-tok-tok con rod bearing sound

having oil in ur radiator is fun too..good luck getting that head gasket changed

i am just saying what is happening in the real world

good luck getting pwned by kancill tebo with ur 4g15 bolt on

in sabah, they used to run 4G15 tebo with AE92 4AGZE MAF ecu

change to 4agze cam angle sensor, injector, maf, coil pack, throttle position..

it can detect boost and inject the correct amount of fuel unlike 4g15 na ecu

those stock NA ecu can never read boost..above 0psi it will all go hairwire because it was never design to read above 0psi and it doesnt have map for above 0psi

what piggyback like safc do it to make them see less pressure..and by fitting in large injector you have some margin of tuning

let say for example stock injector is 150cc, you change it to 200cc which is a 33% increase in size, we assume fuel pressure can be maintained, you will need to set the fuel correction on your safc to run -33% on all rpm for it to inject SAME amount of fuel as stock.

so when running boost, the safc fuel correction can be change to higher value such as -20% -10% 0% so on depend on rpm and boost. this can effectively inject more fuel on 100% HI throttle because u know when the boost come on..let say 3krpm..pretty much consistent

but have you think on half throttle? high load low throttle? low load high throttle? low load low throttle? daily driving condition? the fuel is not accurate at all because boost doenst kick at 3krpm all the time under these condition..yea i know can set the LO throttle correction but still it is inconsistent

another point is, by reducing fuel (because u have switch to bigger injector, safc tell ecu the engine are on low load) from MAP/MAF sensor..most ecu automatically add ignition timing..as stock ecu doesn't read above 0psi..it wont reduce timing as boost come

big timing + boost + inconsistent fuel = ??
