Has any one seen the zoom artical on a ke20 corolla!!! its making some serious power its running1.38bar boost. why carn't an a12 match it?

thats because noone can justify spending huge amounts of money on a a12 motor to get that much power..... u give me an a12 ill put all my turbo parts on it and boost it to 1.38 bar and we will see if we can beat the ke20.......

boost is 1.24bar sorry. i am not up with cost but it seems easy enough the only work to the block is aftermarket rings and pistons so compersission is now 7.43, custom camshaft o- ringed after market pushrods an then shotpeened crank an rods the head flowed pretty well an then they slapped a hks turbo on it. is it expensive?

it starts to add up pretty quick.

The corolla engine is already a far more reliable engine than the A series from stock it was designed from scratch not a carryover from the mini like the A series is. However the A series has better head design for higher performance hands down. If the bottom end can be built right, the A series should blitz the K series engine in overall performance turbo or NA.
The same doesnt go for the L series competitor where in Puerto Rico the 3T series pushrods can reach 700hp boosted and the 3tg twin cam 12 valver can reach 800 plus.

i may be wrong in this case.... but a lot of magazine articles have 'estimated' power outputs..... dont believe everything you read

nope they dynoed this 4 sure. So does any have a guess how much boost a a12 can take with after market pistions( lowering compresion to around 8) an the same treatment to the rods an crank can take? a12's are cheap. don't matter if i kill a few
