60mm Throttle Body


what?
a small size of potato engine using a big 60mm throttle body? kinda retarded rite?lol..
its been a while i've been keeping this TB, waiting for the right moment to fit it. It started to rain after i removed 6 bolts to dismantle the intake manifold...darn...a lil bit delay...!!!,


i bought this TB which is for a Mitsubishi/proton 6a12, a v6 type engine. ISC is being removed and i've ordered a block off plate. the intake manifold is being bored to match the 60mm TB which COST ME A LOT than the price of that TB..!!!..talking bout aluminum stuff eh?..it wont be cheap, since i dun hv the proper tools to get it done by myself.


previously, i wuz using 54mm TB from a 4g93 motor, the response is great, everything is fine. jz i wuz keen to know if there is anything gain from a 60mm TB. so..the result..i lose the response..its not crispy as it use to be..3000rpm - 7500rpm is jz a flat response.. :(...but still, its untune, so will get it tune and hopefully the result will be better(maybe)..or..i'll jz revert back to 54mm TB.. :P
