quick engine ?

What's the difference between the 4g63 and the 420a? im looking for a engine for my 99 gs so any info would be wounderfull! thanks

A 4g63 will not fit unless you have about 7000 dollars to spend.

well that sucks lol.. are there any "better" engines than the 420a that i can put in that will fit?

the 420a is rated at 140 horsepower and is non turbo...it is what should be in your car.

The 4g63 is rated at 210 horsepower and is turboed...It belongs in the GST or GSX.

THe 420a is not a bad motor to put in you should check out the top page about turboing the motor. Sure it is not as powerful as the gst or gsx but it can beat most of the ricey cars you will find in town.

are you talking about if i turbo it or just do some mods.. about beating most of the ricey cars?

Well a turbo would be the fastest but if you add a few mods you should be pretty good.
