ok im finishing up on my boosted b16 build and need a little advice... i have crower valve train dual springs and chromoly retainers already in but i got blox dual springs new in box no retainers yet so im just wondering go with used crower springs with new retainers or new blox springs with new retainers thanks

 

I personally am weary about putting used internals in my car

 

titanium retainers may be lighter but are very brittle and can crack. i always liked oem steel retainers

 

thanks for the tips im goin with the blox dual springs crower chromoly retainers crower stage 2 cams obx tubular manifold garrett t3/t4 .50 trim crower 1mm oversized standard comp valves eagle rods ross 81.5mm pistons 8.5:1 compresson stock crank cometic head gasket vibrant thermal 3.5in str8 back exhaust skunk2 proseries intake manifold and 68mm throttle body with chipped p28 in JDM B16 in an EG hatch any clue how much power i could throw down??

 

stupid question but i also have venom 400 performance control module and MSD SCI-L would those help or should i work without them

 

known good working, quality parts that have lots of life left are fine to reuse. Would you toss your OEM crankshaft since it's used? Would you toss a JDM motor since it's used?

To switch out Crower springs for Blox makes no sense.

I assume the control module and MSD are both ignition parts, and in which case, don't bother. You don't need aftermarket ignition stuff until you start going for like 600-700hp.

 

never said i was tossing them out just have bare si head and couldnt figure out whether i should go with the blox i got new in box or the crower... decided on crower any idea how much hp stock b16 sleeves with .5mm bore would hold??
