D15b Vtec Wanting Turbo

By twc2010
- Sun Aug 08, 2010 3:39 pm #207966 I have a 94 civic dx with a d15b vtec motor. I'm just planning on 5 or 6 psi on my stock motor. Is that okay. If something happens to the motor I'll replace it with a d16z6. The turbo should still fit. I'm getting new injectors and fuel pump and am running a virgin p28 ecu that i plan to get chipped and tuned.

You ever consider a Jackson Racing blower instead of a turbo?

im running a jrsc on a d15b vtec on 8 psi....... AND I LOVE IT. the immediate boost is so much fun. sure you dnt have the high horsepower gains as a turbo but u have the reliability and dependability as a stock motor with no lag....... do it.

or you could pull the d15 right now for a back up motor incase you blow the z6.

also psi isnt relevant to the life of a motor. 6 psi with a gt30 would explode but 6 psi with a kkk wouldn't give you anything. (exageration for point of emphasis) motors break depending on horsepower not boost levels.

not wht i was sayin. its the setup if a supercharger that gives it its reliability. not the psi. :thumb:

jdm d15b vtec has d16 rods.
stock d16 bottom ends can take 220+hp.
if you want bigger numbers, vitara builds can take more than double that.
