quick question people as i have heard so many diffrent answers to this one.
how much can you push a standard ej20 engine i no that the gearbox is a weak point but what could you push out of these engines without changing pistons ect

dlatch

from what i have seen 350bhp seems the absolute tops powerwise and if well looked after.

obviously standard clutch/gearbox's may be on limited life when dealing with that amount of power.

I asked Andy Forrest this question at the begining of the month when having my car mapped. Around 400bhp was his answer providing you dont do 1/4 miles or track days.
He run his 440bhp Impreza on standard internals for over 2 years.

a piece of string and how long ya want it

dependants all depend on the manner ya drive it and the map of said engine .

ya stole it and drove it .hmm not long i guessing

ya got so much torque it spins the top of a milk bottle at 20 paces .hmm gearbox not long

ya a tight git and use d ****e oil and dont change it much .even less than it took me too write this


i not up on the engine code ya gave me .but i guessing as it been said here load s that a closed deck block will maybe take all of the above a little longer than a open

petrol also will be a added factot

lol there so may ifs buts maybe with a open question that we dont wana add any more in case ya sue our ***

madmooro

also how long ya want it too last before the said comes and takes ya wallet for a ride ??

C.J. on here runs just over 400bhp on std internals new age wrx 5sp is maxed out at this and due to go bang. Sti stronger as is the 6sp box.
