i had no reliablilty issues with my ls/vtec.

stock block
gsr head
type-r valve train
and DC 4-1 headers

that setup was redlined everyday for 6-8 months. (with no problem) Then i junked the headers and replaced them with a greddy 18g setup. which also was redlined daily for about a year. (buy redlined i mean 7800 rpms. even though ls bottom ends can not rev that high and still be reliable )

It never leaked oil or smoked one bit. That is a year and a half of constant redline. I have a few people on IA that can vouch for how harsh i was on the setup! It ran fine till the day i pulled/sold the motor and shell. (sold it to buy a 240, now selling my twoforty to buy another integra lol)

To all the people that say it is not reliable maybe you should find a new engine builder/buy better quality parts! thats my
