Eh nobody seems to be answering this thread yet.must be sunday and everyone went out for sunday drive and i'm stuck in office working.hehe.
anyway if u r still with stock internals, keep the boost low.tune it properly and do frequent oil change.as for others must wait for the sifus to comment.
about air filters.i remember a few years back this guy with a silver top 4 throttle ask my mech about the power loss of his engine and when he opened up his hood,his open pod filter was so clogged up you cannot imagine.haha.either he drove in dirt road or his previous mech was an idiot.
I choose to use 4age sivlertop with addition of turbo charger. How to take good care of this type of combination. plz give advice
Use good synthetic oil.
Change oil more frequently.
Use higher octane gasoline.
Thicker head gasket to lower compression a little (4age engines usually are high compression).
Also, turbo timer to cool the off the turbo and to have oil properly drained out of turbo.
Basicly, The Engine Oil Is The First Thing u need to see, what grade u using ? hv u upgrade anything to ur engine beside turbo ? hv u change the piston ? hi or low compression ? dun boost too high if ur piston compression is hi, exp (13.1 > up) hv u change ur ecu cause original ecu will hv the limit and will lock the fuel when reach the limit. add fuel regulator . must hv oil press and oil temp meter with u. that`s my opinion, but the main thing is ur engine oil, becareful not to rev high and remember to change oil whenever its dirty already. scare the conrod bearing will damage.
make sure u install an oil temp and oil pressure gauge...
i prefer to cooldown my engine base on looking at my oil temp gauge compared to using a turbotimer to wait 30sec-1min just to cooldown... with the oil temp, u know how hot the oil is. normal driving should be 85-95deg for oil temp. if between 110-120deg ease off and cooldown the oil..
after hard runs, and ure engine oil is say 120deg... the turbotimer running for 2 mins also will not cooldown the oil to 95deg. u need to drive slow and let the air run thru your oil coolers etc to allow cooldown of the oil back to operating temps...
