What better (and cheaper for building turbo) engine for turbo 10 PSI?

1) F22B (prelude si 96year DOHC comp.ratio 9 160hp)
2) F22B (accord wagon SOHC comp.ratio 8 145hp)


thx

 

i will use JDM engine

 

generally the lower the compression ratio the better for turbo

 

DOHC or SOHC - is not important?

 

not as important as compression ratio, the lower the compression ratio the more boost you can run safely

 

ok thanks.
for turbo, maybe not need swap my F18B (sohc without vtec 125 HP 16.8 kg*m / 4500 comp ratio 9:1) on F22B (sohc 135-145 hp)?

 

i'm not all too familiar with the F18 as it was never offered in the US and isnt a popular swap(dont know anyone who has done that swap in the states) but i would say you could prob save some money and just boost that and not do a swap.

 

on f18b sohc without vtec EXHOUST is 4:1 on F22B 4:2:1
on odometr 262000 km maybe need swap? )))

engine work perfectly

 

the exhaust manifold really doesnt matter if your turboing it as you would need a turbo manifold. and perhaps just rebuild it, would still be cheaper than a motor swap

 

thanks
