if you upgrade the cam and uprgrade valve springs and all that stuff....how high can i rev the d16z6? would i need to upgrade some of engine block stuff too?

 

call the manufacturer of the parts you are looking to install . they designed it so they know what it can take .

 

thanks..i will definitely do that...i want to take out my power steering cause its leaking somewhere, all i do is cut the belt and unbolt it off the engine right?

 

some say to leave the lines on the rack and run a reservoir to contain fluid , but ive gone 5 years on a pwr steering rack with the lines removed and no problems.

i removed the lines completly off the rack and everything out of the car . takes 5 minutes . once you remove the lines though , SLOWLY turn the wheel to remove the fluid in the rack... or you'll have fluid shooting all over the place if you go fast.

 

ok ill try that in the morning. thanks bro. and i have one more question lol sorry. Is the jdm d15vtec cam an upgrade compared to the usdm d16z6vtec cam?

 

the heads and cams are identical on a jdm d15vtec and z6

 

oh ok...people seem to "brag" about havin a jdm d15b so i was just assuming there was something different about it. thanks for all the help i appreciate it!

 

its basically the same engine , but with 1.5l and slightly higher compression . it has 5 more hp and a shorter stroke . same bore size for both engines. nothing special about them , but make for a decent replacement if your looking for a stock swap in your car for cheap.

 

im pretty sure the D15B cam is different then the Z6 ive heard of a few people who have put them in Z6's and had a noticable power difference

 

I put in a zex stage 2 cam with valve springs with a stock bottoem end... it makes power all the way to 8k, and handles it quite well
